Title:
A REDUCER AND AN INDUSTRIAL ROBOT
Document Type and Number:
WIPO Patent Application WO/2021/081864
Kind Code:
A1
Abstract:
A reducer (100) comprises a casing (2), a low speed output part (3) coupled to the casing (2), a high speed input part (4), and a blocking film (6). The high speed input part (4) is coupled to the casing (2) and comprises an input shaft (41). An internal space (5) is enclosed by the casing (2). The low speed output part (3) and the high speed input part (4) are filled with a lubricant. The input shaft (41) comprises a channel (42) communicating the internal space (5) and an external environment. The blocking film (6) is arranged on the input shaft (41) to block the channel (42) and is permeable to air and non-permeable to the lubricant．In this way, the influence of the lubricant on the vent capability of the film could be reduced, such that the internal pressure could be released in time. An industrial robot comprising this reducer (100) is also provided.
