Mechanism for maintaining contact between the driving side of torque transfering surfaces of a first rotatable member and the driven side of matching torque transfering surfaces of a second rotatable member
Abstract A mechanism for maintaining contact between the driving side of spline teeth of a first rotatable member against the driven side of matching spline teeth of a second rotatable member including a coil spring carried by the rotatable second member. One end of the spring has a first tang formed thereon which engages in a hole formed in the first rotatable member and a second tang formed on the other end of said spring engaged in a hole formed in a washer having teeth formed on the inner edge thereof engaged with the splines of the second rotatable member when the washer is rotated relative to the second rotatable member one or more splines of the second rotatable member from static condition of the spring thereby torsionally loading the spring. The spring is compressed longitudinally of the second rotatable member as it is loaded and the spring is secured in place upon the second rotatable member by means of a lock ring in engagement with a circumferential groove formed in the splines of the second rotatable member.
A mechanism for maintaining contact between the driving side of the torque transmitting surfaces of a first rotatable member against the driven side of matching torque transmitting surfaces of a second rotatable member comprising: (a) said first rotatable member having an axial hole with internal splines on the surface thereof forming torque transmitting surfaces, (b) said second rotatable member having elongated splines extending axially on the outer surface thereof forming torque transmitting surfaces in engagement with said internal splines, (c) a helical coil spring encircling said splines on said second rotatable member, (d) means connecting one end of said coil spring to said first rotatable member, (e) a washer having teeth formed on the internal edge thereof engageable with the splines of said second rotatable member, (f) means connecting the other end of said coil spring to said washer, (g) means for preloading said spring including said washer freely rotated on said second rotatable member to torsionally load the spring for engagement of the teeth of the washer with the torque transmitting spline surfaces of said second rotatable member with the spring torsionally loaded.
