1. The machining surface on the two bearing bases is on the same horizontal plane, the center spacing tolerance is 1mm, the longitudinal centerline non-parallelism deviation is 0.5mm, and the horizontal centerline deviation is 0.5mm per meter.

2. The spherical contact surface of the tile seat should be uniformly angled; Not less than 1-2 points per 50X.50mm2; The contact surface between the hollow shaft and the tile should be 90°-100° and not less than 2 points per square inch, and the gap between the journal and both sides of the bearing is approximately the same.

3. The mating surface of the cylinder flange and the front end cover should ensure good contact, no gaskets are allowed, and the tolerance of different shafts of the two hollow shafts is less than 0.8mm. When the ring gear and the cylinder end cover are connected and corrected, they should be firm and thrust, and the positioning pin should be applied, and the radial swing of the ring gear should not be more than 0.5mm, and the axial swing should not be more than 0.84mm.

4. The end cover should be installed first when the liner is installed, and the cylinder liner should start from the population and be carried out according to the assembly requirements, and the screws should be evenly tightened and should not leak. The rubber liner must not have gaps, and the gaps should be blocked with a sponge.

5. The center line of the pinion should be parallel to the center line of the big gear, and its deviation per meter should not be more than 0.2mm. The tooth top gap is 1/4 modulus, the tooth side clearance is 1.06-----1.8mm, the tooth surface contact area is not less than 50% of the tooth length, and the tooth height is 40%.

6. The transmission coupling of the reducer, motor and transmission shaft should maintain a high degree of coaxiality, the different axial degrees of the centerline should not be greater than 0.3mm, and the inclination of the centerline should be less than 1/1000.
