Title:
RACK GEAR MOUNT STRUCTURE AND RACK GEAR
Document Type and Number:
WIPO Patent Application WO/2020/008604
Kind Code:
A1
Abstract:
In this rack gear mount structure for mounting a rack gear (7) on a rack mount surface (8), a rack body member (11) of the rack gear (7) has a plurality of long grooves (13) formed therein. The grooves (13) divide the rack body member (11) at predetermined intervals in the longitudinal direction (11a) thereof other than in a portion of the rack body member (11) in which a rack tooth row (12) is formed. When the rack gear (7) is fastened and fixed to the rack mount surface (8), the rack gear (7) is mounted to the rack mount surface (8) in a state in which deformation of the rack gear (7) is completely corrected by the fastening force applied to the rack gear (7). The rack gear (7) can be plastically deformed by applying a large external force thereto and be machined with excellent accuracy and assembled on the actual machine with excellent accuracy without performing a process for removing deformation in the rack gear.
