　　XNUMX. Purpose and scope of application:

　　The product can be applied to mechanical transmission in metallurgy, mining, transportation, energy, building materials, light chemical industries and other industries.The scope of application is as follows:

　　Generally equipped with Y series three-phase asynchronous motor, the input speed is 1500r/min, and the motor installation form is B5 or B35;

　　For installation at a position where the horizontal output shaft or the downward inclination angle is not more than 200:

　　The ambient temperature is -40-45 ℃.Below0 ℃The lubricating oil should be warmed to0 ℃the above.Higher than45 ℃At the same time, it should be combined with the thermal power check, and the corresponding cooling measures should be taken.

　　XNUMX. Model and mark of reducer:

　　The marking code of the reducer includes the reducer model, nominal center distance, nominal transmission ratio and nominal input power.

　　Markup example:

　　11: Nominal input power Pi=11kW

　　31.2: Nominal transmission ratio i-31.5

　　140: Nominal center distance a=140 mm

　　TY: Coaxial hardened gear reducer

　　Fourth, the size of the reducer:

　　The outline dimensions of the reducer are shown in Figure 1, Table 1, and Table 2.

　　Note: For those with a negative sign in the table, the value is the length of the motor recessed into the reducer.

　　Five, the carrying capacity of the reducer:

　　The nominal input power of the reducer calculated according to the mechanical strength P1.See Table 3

　　按机械强度计算，选用系数K-1.5、2、3时的配用电机功率Pi，见表4、5、6

　　The nominal thermal power PG1 and PG2 calculated according to the maximum equilibrium temperature of the lubricating oil, see Table 7

　　Sixth, the selection of reducer

　　1. The carrying capacity of the reducer is limited by both mechanical power and thermal power. Two power meters must be passed at the same time when selecting.

　　Several coefficients selected:

　　1.1, working condition coefficient KA (table 8)

　　1.2, safety factor Ks (table 9)

　　1.3. Ambient temperature coefficient f1 (table 10)

　　1.4. Load factor f2 (table 11)

　　1.5. Nominal power utilization factor f3 (table 12)

　　XNUMX. How to use simple options :

　　Due to the complexity of the above-mentioned selection method, the following simplified method is proposed for users' reference.

　　For general importance, select a reducer with a small batch and continuous transportation: uniform load K=1.5: medium impact load K=2; strong impact load K=3.Determine the selection coefficient K, and select the reducer from Tables 4, 5, and 6 according to the input motor power and the required transmission ratio i.

　　The reducer selected according to the above K value can no longer be checked for other items.

　　For reducers used in large quantities or important occasions, in order to better balance reliability and economy, please provide detailed supporting technical parameters and contact our company's technical department for selection.

　　XNUMX. Lubrication of reducer:

　　1. Gear lubrication and reducer cooling

　　Usually gears are lubricated by an oil sump, and the reducer is cooled by natural ventilation.

　　When the working equilibrium temperature of the reducer exceeds90 ℃, Or the carrying power exceeds the thermal power P. , Can use circulating oil lubrication (cooling), if the oil sump of the reducer is large and there is space, it can also be cooled by adding a disk-shaped pipe circulating water in the oil sump.

　　For the reducer that has been stopped for more than 24 hours and must be started with full load, circulating lubrication should be used, and circulating oil should be passed before the machine is started, so that the oil supply is normal before starting the main engine.

　　For a machine that has been stopped for a long time but can be started with no load, it should be rotated for a few minutes under no load to make the gears and bearings fully lubricated, and the machine can be operated with load only after it works normally.

　　The amount of oil lubricated by the oil pool, and the oil level should be as high as the oil standard.

　　The amount of circulating lubrication oil is generally not less than0.5L/kW, or calculated by heat balance and bonding strength.

　　When using oil pool lubrication, L-CKD320 (or VG320, Mobi1632) extreme pressure gear oil can be used.

　　When using circulating lubrication, L-CKD320 (or VG220, Mobi1632) extreme pressure gear oil can be used

　　2. Lubrication of bearings

　　When the reducer gear is lubricated by an oil pool, the bearing is lubricated by gear splash oil. When the reducer is cooled by circulating oil lubrication, the bearing is also cooled by circulating oil. At this time, the oil inlet and outlet holes of the bearing need to be provided to fully ensure the lubrication and lubrication of the bearing. Oil circulation.Lubricating oil is the same as gear oil.

　　Nine, installation, use and maintenance

　　1. The axis of the connection between the output shaft of the reducer and the working machine should be coaxial, and the installation error should not be greater than the allowable value of the coupling.

　　2. When gears, sprockets and other transmission parts need to be installed at the end of the output shaft, the following method should be adopted during the design and installation of the transmission system: the direction of the resultant force acting on the reducer should point to the foundation.

　　3. After the reducer is installed, the oil sump of the box body must be filled with suitable lubricating oil to the height specified by the oil standard.The middle engraved line on the oil mark is the horizontal installation position, and the upper engraved line is the installation position.After oil filling, it should be operated without load for a period of time, and it can be put into normal operation after confirming that the operation is stable and without oil leakage.

　　4、首次注入的润滑油需在运转300-600小时后更换。此后，每运转1500-5000小时更新一次，具体时间应根据工作环境而定，但最长更换时间不应超出18个月。在换油时应同时清洗磁性油塞。

　　5. During operation, if there is a sudden increase in oil temperature and abnormal noise, stop and check immediately.It can be put into operation again after correcting the fault.
