Title:
OILED HANGING PULLEY
Document Type and Number:
WIPO Patent Application WO/2024/031748
Kind Code:
A1
Abstract:
Disclosed in the present invention is an oiled hanging pulley, comprising a pulley body; and an oiling mechanism, which moves along with the pulley body, wherein the oiling mechanism oils rolling surfaces of the pulley body when a position change occurs; and the rolling surfaces comprise surfaces of rollers of the pulley body and guide surfaces which come into contact with the pulley body during sliding. The present invention can solve the problems of sliding smoothness and short service life caused by the wear between the hanging pulley and a sliding rail, thereby omitting existing methods for treating the wear; and it is not necessary to remove the hanging pulley or the sliding rail or change the hanging pulley or the sliding rail, such that the wear caused by large quantities is reduced, and steps are reduced, thereby reducing the workload. After oiling, the wear of the rollers and the sliding rail is slowed down, so that the roller and the sliding rail can still slide smoothly after being conventionally worn.
