Title:
LOAD HOLDER FOR KEEPING HIGH LOAD PARALLELISM AND BEARING
Document Type and Number:
WIPO Patent Application WO/2020/063467
Kind Code:
A1
Abstract:
A load holder (30) for keeping a high load parallelism, comprising an annular holder body (31) as well as pre-tightening pieces (32) and gap retaining pieces (33) which are mounted on the holder body (31). The multiple gap retaining pieces (33) are arranged on the inner or outer annular surface of the holder body (31) along the circumferential direction of the holder body (31); the outer circumferential surface of the holder body (31) is provided with multiple limiting holes (312) arranged at intervals in the circumferential direction of the holder body (31), and the inner wall of each limiting hole (312) is fixedly provided with at least one pre-tightening piece (32) for elastically pushing a load (40) along the circumferential direction. The load holder can ensure that an axial high-precision parallelism of loads is kept in the entire transmission process, thereby avoiding noise, vibration, damage and the like in a device operation process to the maximum; the loads arranged axially are in a high-precision axially-parallel state with respect to an axial lead, and the loads can be in free rolling and rolling transmission in a gap between a driving wheel and a driven wheel, thereby greatly prolonging the service life of a bearing.
