What are the reasons for the high temperature at the bearing end of WPWDKS80-60-1.5KW worm gear reducer

The reasons for the high temperature at the bearing end of WPWDKS80-60-1.5KW worm gear reducer are as follows:

1. Lubrication issues

Insufficient or excessive oil level: Oil level below the minimum mark or above the maximum mark will cause an increase in frictional heat.

Deterioration of oil quality: Oxidation of lubricating oil, mixing of impurities, or mismatched viscosity (such as not using 220 # extreme pressure worm gear oil) will reduce the lubrication effect.

2. Bearing malfunction

Bearing damage: direct increase in friction coefficient caused by peeling of raceway, fracture of cage, etc. (normal 0.001, can reach 0.01 or above after damage).

Improper pre tightening force: Over tightening (heating>20 ℃/h) or over loosening (axial displacement>0.1mm) can cause abnormal heating.

3. Installation and Load

Installation deviation: shaft misalignment exceeds the tolerance (>0.1mm) or coupling misalignment is poor, resulting in additional torque.

Overload operation: Continuously exceeding the rated load by 1.2 times, resulting in a sudden increase in bearing temperature.

4. Cooling and Environment

Insufficient cooling: scaling and blockage of the cooler or fan failure, resulting in decreased heat dissipation efficiency.

High temperature environment: When ventilation is poor or the ambient temperature exceeds 40 ℃, heat accumulation accelerates.

5. Other factors

Tight oil seal: The interference between the lip and the shaft exceeds 0.3mm, and the friction coefficient increases from 0.05 to over 0.2.

Manufacturing defect: Worm lead error>0.02mm/100mm, resulting in insufficient contact between the meshing surfaces.
