Description

Technical Field

[0001] This utility model relates to the field of gearbox breathing equipment technology, and in particular to a gearbox breather and a tracked harvester. Background Technology

[0002] The breather is an important component of the gearbox. When the gearbox is operating, the temperature rises, causing the air inside the gearbox to expand. The breather expels the hot air from the gearbox, balancing the pressure inside and outside the gearbox. It also prevents oil leakage from the split surfaces of the gearbox housing and the seals on the shafts.

[0003] Currently, the mainstream breather on the market is a vent plug structure, which is directly installed on the gearbox. Under conditions such as high-speed operation and tilting of the gearbox, lubricating oil inside the gearbox is prone to splashing out, affecting the overall feel of the machine and causing lubricating oil loss.
