FIELD: transport. ^ SUBSTANCE: invention relates to electrified railway transport and may be used in contact suspensions anchored by weight compensators. Proposed chain hoist comprises two interjointed suspensions and wheel with hub arranged the between. Wheel hub is mounted on support surface of antifriction bearing. Said antifriction bearing interacts with working surfaces of aligned grooves of chain hoist suspensions. Bearing assembly is made up of two combined bearing modules fitted on journals of spacer sleeve arranged in said grooves of suspensions and provided with flange arranged at its center, as well as tubular sections formed at sleeve faces to extend beyond suspensions clearance. Every bearing module comprises plain bearing and radial and face sliding bearings arranged on plain bearing inner race surface. Note here that every said module is fitted on aforesaid spacer sleeve as far as it will go to sleeve flange surface. ^ EFFECT: perfected design. ^ 7 cl, 4 dwg |
