BAIL COMPENSATION JOINT FOR RAIL VEHICLES

摘要

A bail compensating joint may include a threaded push rod, a ratchet in threaded connection with the push rod for rotational motion thereon, and a helical joint including a first bearing and a second bearing mounted on the ratchet for facilitating rotation of the ratchet. The second bearing is supported by an annular composite race member formed by a metal annular inner race member joined with a resiliently deformable annular outer member. In another embodiment of the bail compensating joint, a pair of spherical joints is disposed on opposite sides of the ratchet, the spherical joints supporting the respective first and second bearings.

主权项

1. A bail compensating joint, comprising:
a push rod; a ratchet associated with the push rod for rotational motion thereon; and a helical joint comprising a pair of bearings mounted on the ratchet for facilitating rotation of the ratchet, the helical joint further comprising:
a first bearing supported by an annular inner race member and an annular outer race member, the annular inner race member having a first side seated against the ratchet and an opposing second side defining a race track for ball bearings of the first bearing, the annular outer race member having a first side engaged with the ball bearings of the first bearing to permit angular movement of the helical joint; anda second bearing supported by an annular composite race member formed by an annular inner race member joined with an annular outer member, the composite race member supporting the second bearing with the annular inner race member thereof engaging the second bearing and defining a race track for ball bearings of the second bearing, and the annular outer member of the composite race member formed of a resiliently deformable material.
