Instructions for use

 

Use

Cycloidal pin gear reducer adopts the principle of cycloidal pin tooth meshing and planetary transmission, so it is usually called planet cycloid reducer. Planetary cycloid pin gear reducer can be widely used in petroleum, environmental protection, chemical industry, cement, transportation, In textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction, power generation and other industries, as a drive or reduction device, the machine is divided into horizontal, vertical, double-shaft and direct-connected assembly methods.Its unique and stable structure can replace ordinary cylindrical gear reducers and worm gear reducers in many cases. Therefore, planetary cycloid reducers are widely used in various industries and fields and are generally welcomed by users.

Conditions of Use

1. Cycloidal pinwheel reducers are allowed to be used in continuous work situations, while allowing both forward and reverse rotation.Some models of cycloid reducers only allow one-way rotation.

2、输入轴的转速额定转数为1500转/分,在输入功率大于18.5千瓦时建议采用960转/分的6极电机配套使用。

3. The working positions of the horizontally installed cycloid reducer are all horizontal.The maximum horizontal tilt angle during installation is generally less than 15°.When it exceeds 15°, other measures should be taken to ensure adequate lubrication and prevent oil leakage.

4. The output shaft of the cycloid reducer cannot be subjected to large axial force and radial force, and other measures must be taken when there is a large axial force and radial force.

lubricating

1. The horizontal cycloid reducer adopts oil pool lubrication under normal conditions, and the oil level can be kept in the middle of the oil sight window. When working conditions are bad and the ambient temperature is high, it can be lubricated by circulation.

2. Cycloid pinwheel reducer generally chooses 40# or 50# mechanical oil lubrication at room temperature. In order to improve the performance of the reducer and extend the service life of the cycloid pinwheel reducer, it is recommended to use 70# or 90# extreme pressure gears. Oil, lubricating oil should be reconsidered when working under high and low temperature conditions.

3. The vertical installation of the planetary cycloid reducer should strictly prevent the oil pump from cutting off the oil to avoid damage to the parts of the reducer.

4. When refueling, you can turn the breather cap on the upper part of the seat to refuel.When draining the oil, turn the drain plug at the bottom of the main seat to drain the dirty oil.There is no lubricating oil inside the reducer when it leaves the factory.

5. New oil should be replaced for 100 hours after the first refueling operation, (and clean the internal dirty oil), and then continue to work afterwards, and replace it every six months (8-hour work system). If the working conditions are bad, the oil change time can be appropriately shortened. Practice has proved that frequent cleaning and oil change of the reducer (such as 3-6 months) play an important role in prolonging the service life of the reducer.Lubricating oil should be replenished frequently during use.

6. The factory-made reducer has been greased and replaced every six months.The grease adopts aluminum disulfide-2# or 2L-2# lithium-based lubricating grease.

installation

1. When installing couplings, belt pulleys, sprocket and other coupling parts on the output shaft of the cycloid reducer, direct hammering is not allowed, because the output shaft structure of the reducer cannot withstand the axial hammering force. You can use the shaft end screw hole to screw the screw into the coupling piece.

2. The shaft diameters of the output shaft and the input shaft are matched with GB1568-79.

3. The eyebolts on the reducer can only be used for lifting the reducer.

4. When the reducer is installed on the foundation, the elevation of the installation center line of the reducer, the levelness and the relevant dimensions of the connected parts should be calibrated.The concentricity of the calibrated moving shaft should not exceed the allowable range of the coupling.

5. When the reducer is calibrated, it can be carried out with steel spacers or cast iron spacers. The height of the spacers is not more than three, and it can also be carried out with a contract iron, but the reducer should be replaced with flat spacers after calibration.

6. The configuration of the cushion block should avoid causing deformation of the machine body, and should be arranged symmetrically on both sides of the foundation bolts, and the mutual distance can be sufficient to allow the water slurry to circulate freely during irrigation.

7. The irrigation of cement slurry should be dense, without bubbles, voids and other defects.

Glossary

Reduction ratio: the ratio of output speed to input speed.

Number of stages: the number of sets of planetary gears.Generally, the maximum can reach three levels, and the efficiency will be reduced.

Full load efficiency: the transmission efficiency of the reducer under the maximum load condition (the output torque is stopped by failure).

Working life: The accumulative working time of the reducer under rated load and rated input speed.

Rated torque: the torque for long-term operation allowed by the rated life.When the output speed is 100 rpm, the life of the reducer is the average life. When this value is exceeded, the average life of the reducer will be reduced.The reducer malfunctions when the output torque exceeds twice.

Noise: The unit is decibel dB (A). This value is actually measured when the input speed is 3000 rpm, without load, and at a distance of 1 meter from the reducer.

Backlash: The input end is fixed, and the output end rotates clockwise and counterclockwise. When the output end bears plus or minus 2% of the rated torque, the output end of the reducer will have a slight angular displacement. This angular displacement is the return clearance.The unit is "minute", which is 1/60 of a degree.

The following are some of the transmission ratios listed:

Six common sense

1. Large transmission ratio

  摆线针轮减速机具有更高的速比,一级减速时传动比是1:7到1:87;两级减速时转动比为1:121~7569,还有更高的三级减速,客户也可以根据自己的情况选择此类型。

  2. High transmission efficiency

  Cycloidal pinwheel reducer because the gear tooth surface meshing part adopts rolling meshing, there is no relative sliding on the gnawing surface, and the general efficiency can be more than 90%.

  3. Convenient maintenance

  Models below #6125 use high-grade fats that do not require meal protection.

  4. Small size and light weight

  The cycloidal pinwheel reducer adopts the principle of planetary transmission, the input shaft and output shaft are on the same axis, and it is unique in that it is directly connected to the motor, so that its model can be as small as possible.Therefore, the cycloid reducer has the characteristics of small size, compact structure and light weight.Compared with the ordinary two-stage cylindrical gear reducer, the volume can be reduced by more than 2/3; the weight can be reduced by more than 1/3.

  5. Convenient disassembly and assembly, easy maintenance

  Due to the reasonable structural design of the cycloid reducer, simple disassembly and assembly are convenient for maintenance, the number of parts used is small, and the lubrication is also very simple.

  6. Long life and low noise

  Due to the principle of planetary transmission, the number of teeth of the pendulum needle is large during operation, and the overlap coefficient is large. The overall machine body operates in a balanced manner. The main parts are precision ground after quenching with bearing steel, and the wear is minimized, so The noise emitted during operation is low and the service life is long.

Torque calculation

 

Torque of cycloid reducer=9550×motor power÷motor power input revolution×speed ratio×use efficiency (65%-75%)

Oil spill handling

 

In the gear box, bearing box, thread seal, mechanical seal and other parts of the cycloid pinwheel reducer, due to the long-term high-torque mechanical movement, the gear box meshing gap becomes larger, causing greater noise and equipment vibration.In addition, the sealing part has been operating at high speed and high temperature for a long time, and the oil leakage of the sealing part sometimes occurs.Due to the serious oil leakage during equipment operation, which brings many disadvantages to safe production, the traditional method requires a long period of shutdown to disassemble and replace the sealing gasket and treat the joint surface. In order to achieve effective treatment during equipment operation, traditional methods cannot be achieved.In the 21st century, the method of adding new lubricants can be used to solve this problem. Among many materials, the better application effect is Metre Super Sealant & Lubricant, which has super self-lubricating performance and reduces the gap between the meshing parts. , Effectively alleviate the problem of equipment noise and oil leakage at the dynamic seal part.Super lubricant is an oil additive that will not pollute or deteriorate the oil. It can solve the hidden safety hazards in the production without stopping the machine and save the company high maintenance or replacement costs.

Common malfunctions

 

In the long-term operation of the reducer, failures such as wear and leakage will often occur. The most important ones are:

1. Wear of the bearing chamber of the reducer, including the wear of the housing bearing box, the bearing chamber of the box bore, and the bearing chamber of the gearbox

The reducer is one of the main equipment of the enterprise. Once the matching clearance occurs during the operation, it will cause serious damage to the transmission shaft and gears, causing a major shutdown and production accident, and the enterprise will suffer huge economic losses.Once the bearing chamber of the reducer is worn, the replacement cost of the parts is high, and the manufacturing cycle is long. The general repair method is to disassemble and repair the welding, machining or reaming and inserting the steel sleeve, which is time-consuming, labor-intensive, and expensive.Western countries mostly use polymer composite materials to solve the wear problem of the reducer bearing chamber. Among them, the better application effect is the Mega Wah series, which has mechanical properties and good plasticity, which greatly shortens the repair of the equipment while ensuring the normal operation of the equipment. Time creates huge economic value for the enterprise.

This type of problem is generally difficult to repair and solve with repair welding technology. The weldability of cast iron is not good and it is easy to cause more serious secondary damage to the parts during welding, and the replacement cost is high and the time is long.The unique compressive strength, good plastic deformation and super machining performance of Mega Wah polymer composites show fast, convenient and durable characteristics when repairing such problems, saving companies a lot of valuable downtime. And it enables the company to learn a new set of repair and maintenance technology, and when it encounters a similar problem again, the company can solve it on its own in the first time.

2. The shaft diameter of the gear shaft of the reducer is worn, and the main wear parts are the shaft head, keyway, etc.

3. The bearing position of the drive shaft of the reducer is worn

4. Leakage on the joint surface of the reducer

In view of the wear problem, the traditional solution of the company is repair welding or machining and repair after brush plating, but both have certain drawbacks: the thermal stress generated by the high temperature of repair welding cannot be completely eliminated, and it is easy to cause material damage and cause the parts to bend or break; However, electric brush plating is limited by the thickness of the coating, which is easy to peel off, and the above two methods use metal to repair the metal, which cannot change the "hard-to-hard" coordination relationship. Under the combined action of various forces, it will still cause re-wear.For some large bearing companies, it is impossible to solve on-site, and most of them have to rely on outsourcing to repair.Contemporary Western countries mostly use polymer composite repair methods to deal with the above problems, and the most widely used are the products of Mega Wah technology, which have super adhesion, excellent compressive strength and other comprehensive properties.The application of polymer materials for repair can avoid disassembly and machining. There is no thermal stress for repair welding, and the repair thickness is not limited. At the same time, the product has the retreat of the metal material, which can absorb the shock and vibration of the equipment and avoid re-wearing. Possibly, and greatly extend the service life of equipment components, save a lot of downtime for enterprises, and create huge economic value.

For the leakage problem, the traditional method needs to disassemble and open the reducer, replace the sealing gasket or apply sealant, which is time-consuming and laborious, and it is difficult to ensure the sealing effect, and leakage will occur again during operation.Mega Wah polymer material can treat leakage on site. The material has superior adhesion, oil resistance and 350% stretch, which overcomes the impact of reducer vibration and solves the problem of reducer leakage for enterprises.
