Title:
PRESSURE RELIEF COMPONENT, GEARBOX AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/193062
Kind Code:
A1
Abstract:
A pressure relief component (100) for a gearbox (200), comprising: a gas-permeable film (101) arranged adjacent to an internal chamber (201) of the gearbox (200) for receiving lubricant and adapted to allow passage of gas but prevent passage of the lubricant; and a fixing member (102) arranged on a side of the gas-permeable film (101) away from the internal chamber (201) to hermetically fix the gas-permeable film (101) in position, the fixing member (102) comprising a through hole (1023) for the gas passing through the gas-permeable film (101) from the internal chamber (201) to escape. With the pressure relief component (100) comprising the gas-permeable film (101) and the fixing member (102), during the operation of a gearbox (200), gas within the internal chamber (201) can pass through the gas-permeable film (101) and escape to the external environment. In this way, the pressure within the internal chamber (201) can be maintained at a relatively low level. This ensures the sealing system of the gearbox (200) works within a safe pressure range, thereby ensuring the effectiveness of the sealing system and improving the reliability of the gearbox (200).The disclosure also provides a gearbox (200) and a robot.
