Document Type and Number:
Japanese Patent JPS6170222
Kind Code:
A
Abstract:
PURPOSE:To prevent movement and abnormal vibration of a bearing, by a method wherein a small size part is formed to a projection part protruded from the end, on the side reverse to an engaging part, of the support body of the bearing of an electric motor, such as hot water circulating pumps, and a lock member, engaged with the small size part, is engaged with the end, on the side reverse to engaging part, of the support body. CONSTITUTION:Water sealing members 7 and 9 are engaged with a step outer peripheral surface 6b of a bearing support 6 on the side reverse to the load side and a step outer peripheral surface 8b of a support body 8 on the load side. Small parts 11a and 12a are formed on a projection part from the forward end surface of the step outer peripheral surface 6b of a cylinder bearing 11 and a projection part from the forward end surface of the step outer peripheral surface 8b of a cylinder bearing 12. Inner peripheral surfaces of annular locking members 21 and 22 are engaged with the small parts 11a and 12a. The outer peripheral surfaces thereof are formed in a size larger than those of the step outer peripheral surfaces 6b and 8b, so that water sealing members 7 and 9 are prevented from disengagement from the step outer peripheral surfaces 6b and 8b, and the outer peripheral surfaces are threadedly coupled with the forward end surfaces of the step outer peripheral surfaces 6b and 8b.
