Abstract

A combination of parts cooperating with a wheel supported on a shaft by bearings in which there is a lock nut threaded on said shaft into a position for accurate adjustment of the bearing means of the wheel in combination with a lock ring for locking said nut in an accurate position and in combination with accurately formed retaining and mounting ring whereby a sensor for sensing the action of a wheel under braking conditions can be mounted on said nut in a position adjacent to the end of the shaft with the sensor being concentric and axially aligned.

Claims

1. In combination with a means for mounting a rotating part and bearing means on a shaft whereby the rotating part and bearing means may be accurately adjusted and in combination with a sensor for sensing the function of a part related to the rotating part, the combination including:

a. a shaft on which the rotating part and bearing may be mounted, said shaft having a threaded portion;

b. a nut on said shaft having threads engageable with the threads on the shaft and having annularly arranged serrations;

c. removable nut holding means engageable with said shaft so that it may have but one circumferential position and having annularly arranged serrations engageable with the serrations of said nut whereby said nut may be held in a predetermined rotational and axial position and upon removal of the nut holding means, may be moved into different circumferential and axial positions and held in such other positions by replacement of said nut holding means;

d. nut holding retainer and mounting means mounted on said nut for holding said removable nut holding means in holding position with respect to said nut;

e. securing means for securing said removable nut holding and mounting means in a concentric and axially aligned position with respect to said nut and the axis of the shaft on which said parts are mounted; and

f. a sensor mounted on said securing means.

2. A combination as defined in claim 1 in which said removable nut holding means fits into a recess in said nut, in which the serrations are circumferentially arranged thereon to engage serrations in said recess and in which said removable nut holding means is held in a precise circumferential position by an inwardly extending key which extends into an axial keyway formed in said shaft.

3. A combination as defined in claim 1 in which said nut holding retainer and mounting means has an annular projecting lip and in which a mounting body of a sensor is secured against an end face of said nut holding retainer and mounting means and is engageable with a cylindrical surface of said lip for mounting said mounting body in an exact concentric and radial position.

4. A combination as defined in claim 3 in which the mounting body of said sensor is secured to said nut holding retainer and mounting means by a securing plate and in which the attachment is effected by relative rotational movement between said nut holding retainer and mounting means and said mounting body.

5. In combination with a wheel mounted on bearing means on a shaft whereby the wheel and bearing means may be accurately adjusted and a sensor for sensing the functioning of brake means associated with said wheel, the combination including:

a. a shaft on which said wheel and bearing means are mounted, said shaft having a threaded portion;

b. a nut on said shaft having threads engageable with the threads on said shaft and having an annular recess surrounding said shaft, the outer annular surface of said recess being formed with annularly arranged axial serrations;

c. a nut lock ring positioned in said recess and having means cooperating with said shaft so that said nut lock ring has a fixed circumferential position and in which said lock ring has external circumferentially arranged serrations engageable with the serrations on said nut in the recess thereof whereby said nut may be held in a predetermined rotational and axial position and upon removal of said nut lock ring, said nut may be moved into a different circumferential and axial position and thereafter held in such new position upon replacement of said nut lock ring;

d. a lock ring retainer and mounting ring secured to said nut in a substantially exact circumferential and axial position, said lock ring retainer and mounting ring holding said nut lock ring in said recess and also acting as a mounting means whereby said sensor may be mounted on said nut in exact concentric and axially aligned position; and

e. annular recess and projection means cooperating between said lock ring retainer and said nut and concentrically arranged with respect to the axis of said shaft, said parts cooperating to hold said lock ring retainer and mounting ring in an accurate circumferential and axial position.
