Description

Lengthened oil leakage prevention ventilation cap structure

Technical Field

The utility model relates to the technical field of breathable caps, in particular to a lengthened oil leakage prevention breathable cap structure.

Background

In the running process of the gear box, when the gears are meshed to move, the lubricating oil in the box body can be driven to be accumulated to the ventilation cap due to the limitation of the internal space of the box body in the gear box with compact internal structure, and the whole length of the conventional ventilation cap is too short, so that accumulated oil does not have a buffer space. The function of the ventilation cap is mainly ventilation and pressure regulation, and mainly solves the problem of pressure rise in the gear box caused by oil temperature rise. When the oil temperature is too high, the accumulated oil at the air permeable cap can flow out of the box body along with the air pressure at the air permeable cap. This results in a large overflow of the pressurized oil.
