FOREIGN-MATTER INTRUSION PREVENTIVE DEVICE FOR SLEWING DRIVE

摘要

PURPOSE: To simplify a constitution for preventing the intrusion of grease in a slewing drive and to obviate the damage of a pinion gear and a ring gear even when a component is slipped off. ;CONSTITUTION: A seal ring 28 is fitted to a driving output shaft in adjacency to a pinion gear 24. A ring cover 31 made of a rubber is fitted onto the outer circumferences of the mating contacting sections of the seal ring 28 and the pinion gear 24. A projecting section 31a and a lip section 31b are formed to the ring cover 31, and a bundle wire 32 consisting of a flexible material such as the rubber, nylon, etc., is wound between the projecting section 31a and the lip section 31b, thus fixing the ring cover 31.;COPYRIGHT: (C)1995,JPO
