1.1 Precautions before installation

Assembly and installation work must be carried out carefully by trained and qualified personnel;
The manufacturer is not responsible for any damage caused by incorrect assembly and installation;
In the planning stage, sufficient space should be reserved for the reducer for future maintenance and repair work;
Be sure to prepare suitable lifting equipment before starting assembly and installation work;
If the reducer (motor) is equipped with a fan, there should be enough space to be able to suck in air;
The description on the nameplate of the drive is consistent with the on-site power supply;
The transmission device should be intact (not damaged during transportation or storage);
Confirm that the following requirements have been met:
For standard reducer: ambient temperature 0°C~+40°C
No oil, acid, harmful gas, steam, radioactive objects, etc.;
For special types: the transmission device is configured according to environmental conditions;
For the worm gear reducer: the reducer with self-locking function cannot be used
Excessive reverse external moment of inertia is applied to avoid damage to the reducer;
In order to ensure good lubrication, the installation position specified in the order must be observed;
Be sure to pay attention to the warning and safety signs of the reducer (motor).

1.2 Preparations before installation

Use commercially available solvents to thoroughly remove preservatives, dirt or the like on the surface of the output shaft and flange;
Note: Do not immerse the solvent on the sealing lip of the oil seal, otherwise the solvent may damage the oil seal;
If the reducer is stored for more than 1 year, the service life of the lubricant in the bearing will be shortened;
If the filling is mineral oil or synthetic oil (CLPHC), and the filling amount is consistent with the requirements of the installation position, the reducer can be operated at any time in this case.However, check the oil level before starting;
In some cases, synthetic oil (CLPPG) is added, and the oil level is higher. Correct the oil level before starting.

1.3 Installation of reducer

The reducer (motor) can only be installed on a flat, shock-absorbing, torsion-resistant support structure according to the specified installation position; the bottom of the box and the mounting flange cannot be tightened at the same time during the installation process to avoid mutual competition;
When using bolts or foundation blocks to fix the reducer (motor) on its concrete foundation, there should be a suitable groove to accommodate the reducer (motor);
When installing, please check whether the amount of oil is consistent with the installation position. If the installation position changes, please adjust the oil amount accordingly;
Install a straight-through breather or open the breather to transport the rubber ring;
Do not hit or knock the shaft end;
The vertical installation of the motor should have shielding measures to prevent foreign objects or liquids from intruding (rain cover C);
When installing the junction box, make the cable inlet point downward.

1.3.1 Installation of solid shaft reducer (motor)

Install and fix input and output drive parts (such as coupling parts, etc.) on the shaft of the reducer;
If these parts need to be pre-heated before installation, please refer to the dimension drawing in the coupling file for the correct mating temperature;
The misalignment of the shaft may be caused by assembly or actual operation (such as thermal expansion, shaft deflection, insufficient rigidity of the frame, etc.);
For the permitted alignment error of the coupling, please refer to the manual of the corresponding brand coupling;

Permissible misalignment error

The centering should be carried out in two axial planes that are perpendicular to each other.Straightedge (radial misalignment) and feeler gauge (angle misalignment) can be used for alignment;
Unless otherwise specified, these parts can be preheated by induction heating, or by burner or in a heating furnace.

1.3.2 Installation of hollow shaft reducer (motor) with flat key

The end of the solid shaft of the working machine should be equipped with a type A flat key in accordance with the first part of DIN6885 standard, and there should be a center hole in accordance with DIN standard 322 DS (threaded) on its end surface;
Check the hollow shaft of the reducer and the solid shaft of the working machine for damage to the shaft seat and edge parts; if necessary, repair and clean up with suitable tools;
Install the reducer with nuts and screws, and the reaction force is provided by the hollow shaft of the reducer;

1 Solid shaft of working machine 2 Reducer hollow shaft 3 Flat key 4 nut 5 screw 6 nut 7 End plate
1 Solid shaft of working machine 2 Reducer hollow shaft 3 Flat key 4 nut 5 screw 6 nut 7 End plate

In addition to the nuts and screws shown in Figures 1 and 2, other types of devices can be used, such as a hydraulic lifting device.

1.3.3 Installation of hollow shaft reducer with expansion plate

The end face of the solid shaft of the working machine should be equipped with a center hole conforming to DIN standard 322 DS (threaded);
Install with integral bushing;
Install the reducer with nuts and screws; the reaction force is provided by the hollow shaft of the reducer;
Install with loose bushings;
Push the loose bushing onto the solid shaft of the working machine, use a positioning device to firmly fix it in place, and then pull it into the hollow shaft of the reducer along the solid shaft of the working machine (refer to Figure 1 and Figure 2) ;
The outer surface of the hollow shaft of the reducer can be greased on the position of the shrink disk seat;
Tighten all the fastening bolts one by one in order, and tighten all the bolts after several cycles;
Tighten the fastening bolts until the front sides of the inner ring and outer ring are aligned.
