In the planning phase, enough space should be left for maintenance and repair work of reducer in the future;
Before starting the assembly and installation work, must prepare the appropriate hoisting equipment;
If reducer (motor) is equipped with a fan, then you should leave enough space for it to inhale air;
Actuator nameplate instructions should conform with the power supply;
Gear should be intact (not damaged) in the process of transportation or storage;
Make sure following requests have been meeted:
For standard reducer: environment temperature 0 ° C ~ + 40 ° C
No harmful gas, steam, oil, acid, radioactive objects and etc;
For special type: transmission device is configurated based on environmental conditions;
Worm gear reducer: not applicable for self-locking reducer;
Apply too much adverse external moment of inertia, so as not to damage the reducer;
In order to guarantee good lubrication, must comply with the location requirements of order installation;
Be sure to pay attention to speed reducer (motor) warning and safety sign;

1.2 Installation preparation work

Use solvents to remove the flange, dirt or analogues on the surface of shaft and preservative;
Note: do not make solvent into oil seal's sealing lip, otherwise the solvent may get damaged on oil seal;
If the reducer is stored more than 1 year, the service life of bearing lubricant will be shorten;
If refill mineral oil or synthetic oil (CLPHC), and the amount are in conformity with the requirements of the installation position. The reducer is able to run at any time in this case. But, still have to check the oil level before starting;
In some cases, the filling is synthetic oil (CLPPG), oil level should be higher and correct oil level before starting.

1.3 Reducer installation

Reducer (motor) can only be the installed according to the rules on flat, vibration and torsional support structure; During the installation process, cabinet foot and flange can't be tighten to avoid competing at the same time;
When using bolt or foundation block to fix reducer (motor) on the basis of concrete, there should be suitable grooves for reducer (motor);
When installation, please check whether the oil quantity is consistent with installation location, if the installation position changes, please adjust oil;
Install cut-through ventilator or turn on the ventilator transport rubber ring;
Don't crash and tap on the shaft end;
Vertical installation of the motor should have coverings to prevent liquid or other things to getr in;
When install junction box, make sure the cable service entrance point down.

1.3.1 Solid shaft reducer (motor) installation

Install and fix input and output drive components on the shaft of reducer (such as the coupling parts, etc.);
If these parts need to preheat before installation, please see the coupling in the file size figure about the right temperature;
Shaft's unmatching may be caused by assembly or actual operation, such as thermal expansion, the deflection of shaft and insufficient stiffness of frame, etc.);
Coupling permitted misalignment ratio refers to the corresponding brand coupling instructions;

Permitted misalignment error

Misalignment should be done in the two axis perpendicular of the plane. Can use the ruler (of the radial) and feeler for misalignment;
Unless otherwise specified, these components can use induction heating method to preheat, can also use burner or heating furnace.

1.3.2 Hollow shaft reducer (motor) installation

Work machine solid shaft should be equipped with the first part A flat key that comply with DIN6885 standard type, and there should be 322 DS type (threaded) center hole on its surface according to DIN standard;
Check if the reducer hollow shaft and solid shaft work machine have shaft seat and edge part damage; If necessary, use right tools to repair and clean;
Install reducer with nut and screw , the reaction force is provided by reducer hollow shaft;

1 Work solid shaft 2 Reducer hollow shaft 3 Flat key 4 Nut 5 Screw 6 Nut 7 End plate
1 Work solid shaft 2 Reducer hollow shaft 3 Flat key 4 Nut 5 Screw 6 Nut 7 End plate

In addition to those nuts and screws shown in figure 1 and figure 2 , you can also use other types of devices such as a set of hydraulic lifting device.

1.3.3 The installation of Hollow shaft reducer with swelling

Work machine solid shaft should be equipped with 322 DS type (threaded) center hole that comply with DIN standard;
Use integrated bushing for installation;
Use nut and screw to install speed reducer; Reaction force is provided by reducer hollow shaft;
Use loose sleeves to installation;br> Take loose bushing on machine solid shaft, use a positioning device to firmly fix it in place, and then along the working machine solid shaft pull it back into the hollow shaft of the reducer (refer to figure 1, figure 2);
The outer surface of the hollow shaft of reducer can add grease on the contraction of the disc position;
Fasten bolts in sequence one by one, make sure all bolts are tightened;
Tighten the bolt until the inner ring and outer ring are in alignment.
