What are the preventive measures for oil leakage at the joint surface of ZSY gear reducer

The preventive measures for oil leakage on the joint surface of ZSY gear reducer mainly include optimizing structural design, strengthening sealing treatment, and standardizing maintenance operations. The following are specific solutions:

1. Ensure the machining accuracy of the joint surface

The flatness and roughness of the joint surface should be controlled within a reasonable range (such as flatness error ≤ 0.1mm/m) to avoid sealing failure caused by deformation or poor processing. Castings should undergo aging treatment before manufacturing to eliminate internal stress and prevent deformation during use.

2. Set up return oil groove and annular oil passage

Design an annular oil return groove on the dividing surface of the box, and ensure that it is connected to multiple oil return holes, so that the lubricating oil splashed onto the inner wall can quickly flow back to the oil pool, reducing the accumulation at the joint surface.

3. Using high-quality sealing materials

Apply liquid sealant or anaerobic adhesive to the joint surface instead of traditional gaskets to improve the sealing effect. For areas with large gaps, a combination of sealant and gasket can be used.

4. Keep the ventilation hole unobstructed

Install a ventilation cover or plug at the top of the reducer to ensure pressure balance between the inside and outside of the box, preventing oil from being squeezed out of the joint surface due to increased internal pressure. Regularly clean the ventilation holes to avoid dust blockage.

5. Standardize assembly process

Thoroughly clean the joint surface during assembly, remove oil stains and old glue; The bolts should be tightened evenly in diagonal order to avoid deformation caused by uneven local stress.

6. Control the oil level within the standard range

The oil level height should be between 1/2 and 2/3 of the dipstick to avoid excessive oil filling, which may cause an increase in internal pressure and lubricant overflow.

7. Regular inspection and maintenance

It is recommended to replace the seals every 2000-3000 hours of operation or annually to prevent leakage caused by aging; At the same time, regularly check whether the fastening bolts on the joint surface are loose.
