Title:
回転駆動装置
Document Type and Number:
Japanese Patent JP7464379
Kind Code:
B2
Abstract:
Provided is a rotation drive device (1), which has a driving-force transmission mechanism (7) configured such that a drive transmission member (9) provided on a driving shaft (8) and a disk-shaped driven member (10) attached to a main shaft (4) are directly or indirectly engaged with each other and which is further configured such that an increase in diameter of the driven member (10) due to thermal expansion can be suppressed as much as possible. The driven member (10) includes an inner ring (11) attached to the main shaft (4), and an outer ring (12) attached to the inner ring (11) by shrinkage fit and having an engaging groove (13) formed to be opened on an outer circumferential surface (10b) thereof. The inner ring (11) is formed by a low thermal expansion member, which is an alloy having a thermal expansion coefficient of 5×10-6/K or less. The outer ring (12) is formed of a hardenable iron-based material.
