Title:
ROTARY ACTUATOR
Document Type and Number:
Japanese Patent JPS60102862
Kind Code:
A
Abstract:
PURPOSE:To improve the rigidity of a bearing by supporting a rotational shaft to a housing by a bearing set in which a plurality of bearings are laminated. CONSTITUTION:Two bearings of the same size are laminated axially to construct stationary and free side bearing sets 10, 11. These sets 10, 11 are bonded at the outer races of the bearings to the housing 1, and at the inner races to a rotational shaft 2. These sets 10, 11 are desired so that the types, size and radial gap of the two used bearings are equal. The sets 10, 11 increase in the rigidity and the mechanical resonance point of a rotary actuator is heightened.
