Definitions

  • the spline wear gauge disclosed herein comprises several forms which may be utilized for gauging external or internal splines.
  • Each form comprises two gauge members having circumferentially spaced spline teeth, the teeth on one of the members having an addendum longer than the teeth on the other of the members.
  • the members are rotatable relative to one another so that when they are brought into position adjacent the spline being gauged and rotated relative to one another, one of the members contacts the spline teeth of the spline being gauged at a different position when the other of the members. Any wear on the teeth will be evident by a relative rotational movement that is shown visually by a dial indicator on the gauge body.

  • the problem to which the applicant's invention is directed may be better understood by describing a portion of a workpiece W having spline teeth T, the wear of which is to be gauged.
  • the surfaces S of the teeth which are normally hardened wear, the wear occurring because of the intermeshing of the teeth of the spline with the teeth of a mating spline member.
  • the surface S wears in use with respect to a portion of the tooth near the base thereof S".
  • the splines conventionally have convolute configurations in accordance with generally accepted standards wherein the shaped portion of the teeth extend radially beyond the pitch diameter to insure good tooth contact throughout.
  • the portion S" is of correct configuration and therefore the displacement angularly between the surfaces S" and S is a measure of the wear on the teeth.
  • the wear is measured by providing two gauge members 20, 21, that are coaxial and have teeth 22, 23, respectively, the addendum on the teeth 22 being shorter than the addendum on the teeth 23.
  • the gauge members 20, 21 which normally have their teeth axially aligned are brought into position adjacent the spline of the workpiece W which is to be gauged and they are rotated relative to one another, the surface of the teeth 22 will engage the surfaces S and the surface of the teeth 23 will engage the surface S producing a relative displacement between the two members 20, 21 as a measure of the amount of wear of the spline teeth.
  • the gauging members 20, 21 are mounted in a body 25 that includes two sections 26, 27. As shown in FIG. 5, gauging member 20 is telescoped within an opening 27 in body section 26 and a screw 28 extends through the gauging member 20 into engagement with an opening in the body section 27.

  • a pushing gauging member 32 is rotatably mounted in a cavity 27a in body section 27 and in fixed gauging member 20.
  • Gauging member 32 includes spline teeth 33 having a length substantially equal to the length of the teeth 22, namely, having a shorter addendum.
  • pushing gauging member 32 includes a radial projection 34.
  • Projection 34 extends into a cavity 35 of a slide 36 that is adapted to be moved transversely in an opening 37.

  • the position of the slide 36 is controlled by a knob 38.

In the position shown in FIGS. 1 and 3, the pin 39 maintains the slide 36 and, in turn, the pushing gauging member 32 in a centered position wherein the teeth 33 of the pusher. are axially aligned with the teeth 22, 23 of the gauging members 20, 21.
  • a spring-loaded ball 41 is, urged by a spring 42 against a notch 43 in the periphery of the movable gauging member 21, thereby tending to center the gauging member 21.
  • a spring-loaded detent ball 44 in the knob 38 is adapted to engage selectively openings or recesses 45, 45a, 45b in the body section 27 so that the knob can be rotated in one direction or another bringing the detent 44 into engagement with one of the openings 45a, 45b.
  • the pin 39 is displaced causing the slide 36 to become displaced to the right or the left, as viewed in FIG. 3 against the action of one of the springs 38b, 38a.
  • the gauge further includes a dial indicator 46 of conventional construction having a plunger 47 that is adapted to engage a pin 48 on the movable gauging member 21 and move therewith to indicate the relative displacement of the gauging member 21 with respect to the gauging member 20.
  • the spline to be gauged is brought into position with the teeth of the spline being gauged adjacent the teeth 22, 23, 33.
  • the knob is then rotated in one direction or another to bring the detent 44 into engagement with one of the openings 45a, 45b depending upon which side of teeth are to be gauged for wear.
  • This moves the slide 36 through pin 39 yieldingly urging the pushing member 32 through one of the springs 38a, 38b and projection 34 against one surface of the teeth of the spline being gauged.

  • a first tubular gauging element 54 is fixed to the body section 51 and extends axially therefrom. The end of the section 54 is provided with circumferentially spaced spline teeth 55.
  • a second tubular gauging member 56 is rotatably mounted within the tubular member 54 and has radially extending teeth 57 adjacent to teeth 55.
  • a third pushing gauging member 58 having teeth 59 is fixed by a pin 59 on a rod 60 which is concentric with the members 54, 56 and extends axially through a space 61 in the body section 51.
  • a bushing 62 is fixed on the rod 60 and is journalled in an opening 63 in the body section l.
  • Bushing 62 includes a radial projection 64 that extends into a cavity 65 of the slide 66 that is mounted for transverse movement in an opening 67.
  • springs 68 interposed between the projection 44 and the end of slide 66 yieldingly urge the pushing gauging member 58 toward a central position with respect to the cavity.
  • a knob 70 is journalled on the housing section 52 and is provided with an eccentric pin 7l thereon that extends into a slot 72 in the slide 66 to control the position of the slide.
