What are the inspection standards for the connection status between the motor and ZSY200-50-3 gear reducer

The inspection standards for the connection status between the motor and ZSY200-50-3 gear reducer should be developed around three core dimensions: coaxiality accuracy, fastener tightness, and operating state parameters. The specific indicators and requirements are as follows:

1. Accuracy standards for coaxiality and levelness

Radial runout tolerance: The radial deviation between the motor shaft and the input shaft of the reducer is ≤ 0.05mm (use a dial gauge to evenly take 4 measuring points on the circumference of the coupling, and take the maximum deviation value).

Angular runout tolerance: The angular deviation of the coupling end face is ≤ 0.03mm/m (based on the coupling diameter, the difference between the end face measurement points and the diameter ratio must meet this requirement).

Base levelness tolerance: The longitudinal and transverse levelness deviation between the motor base and the reducer base is ≤ 0.05mm/m (tested with a frame level or electronic level).

Adjustment requirements: When the accuracy exceeds the tolerance, it is necessary to adjust it by adding or removing metal shims. It is strictly prohibited to use cutting or tapping the shaft end to forcibly level it.

2. Inspection standards for connectors

Coupling components: The elastic column pin/plum blossom elastic body has no aging, cracking, or deformation, and the clearance with the pin hole is ≤ 0.1mm; the coupling bolts are complete, and the tightening torque meets the specifications (such as M10 bolt torque of 40-50N · m, M12 bolt torque of 80-100N · m, please refer to the equipment manual for details), and the bolts have no slipping or shear deformation.

Flat key and keyway: The fit between the key and the shaft groove, as well as the hub groove, is a transitional fit with a clearance of ≤ 0.1mm. The key is not loose, worn, or deformed, and the keyway has no broken edges or rust.

Anchor bolt: The bolt is not loose or corroded, and the tightening torque meets the design value (M16 bolt torque 180-220N · m). The bolt and nut fit without slipping teeth, and the flat washer and spring washer are complete and not faulty.

3. Operating status monitoring standards

Vibration index: The vibration speed of the coupling part is ≤ 2.8mm/s (in accordance with ISO 10816 equipment vibration standard), there is no obvious abnormal shaking, and the vibration frequency does not have significant fluctuations synchronized with the speed.

Temperature index: The temperature rise of the coupling, motor bearing, and input shaft bearing of the reducer is ≤ 40 ℃ (relative to the ambient temperature), the maximum working temperature is ≤ 80 ℃, and there is no local overheating phenomenon.

Noise index: There is no periodic impact sound or sharp whistling sound during operation, and the noise value is ≤ 85dB (detected at a distance of 1m from the equipment).

4. Protection and Coordination Surface Standards

Coupling protective cover: The protective cover is intact, firmly fixed, without looseness or deformation, with a gap of ≥ 20mm between it and the coupling, and without friction interference.
