Abstract

906,778. Universal joints. GAR WOOD INDUSTRIES Inc. Aug. 4, 1960 [Aug. 20, 1959], No. 27042/60. Class 80 (2). [Also in Groups XXVIII and XXIX] A pair of universal joints 172, 174 connected by a splined shaft 170 are used in a pump (see Group XXVIII) for drivingly connecting a drive shaft 42 to a rotatable cylinder block 60 and to a rotatable swash plate 150 which is tiltable about an axis at right angles to the drive shaft axis. Joint 172 has an inner member 176 integral with shaft 170 and provided with convex teeth 175 in radial alignment with straight teeth 181 within a recessed portion 50 of shaft 42 so that member 176 can move axially relative to member 50. Driving balls 178, located between grooves 177 and 191, have centring balls 171 on either side which ride on a surface 185 of a retaining ring 183 and on a surface 187. Joint 174 has an inner member 186 splined on shaft 170 and provided with convex teeth 188 which engage concave teeth 194 on component 150 to hold inner member 186 against axial displacement. Driving and centring balls are also employed in joint 174.
