Abstract

A flexible and separable drive coupling, which is adapted for constant velocity motion transmissions, is disclosed and shown in Figures 1A and 1B. The coupling 1 consists of slotted drive and driven coupling barrel assemblies 4 and 5 respectively, which can be replaced using a set screw (not shown) independent from the drive shaft 2 and driven shaft 3. A spring-loaded intermediate shaft 6, with dowel pins 7 and 8 that are pressed into the ends of knuckle joints 9 and 10, respectively, is captivated in the drive end of coupling assembly 4 by spring clip 11. Dowel pins 7 and 8 slid within barrel slots 13 and 14, respectively, to compensate for axial and angular misalignments of up to k .12m and f

SEPARABLE DRIVE COUPLING WITH IMPROVED LOW FREQUENCY MOTION QUALITY(Cont'd)

A flexible and separable drive coupling, which is adapted for constant velocity motion transmissions, is disclosed and shown in Figures 1A and 1B. The coupling 1 consists of slotted drive and driven coupling barrel assemblies 4 and 5 respectively, which can be replaced using a set screw (not shown) independent from the drive shaft 2 and driven shaft 3. A spring-loaded intermediate shaft 6, with dowel pins 7 and 8 that are pressed into the ends of knuckle joints 9 and 10, respectively, is captivated in the drive end of coupling assembly 4 by spring clip 11. Dowel pins 7 and 8 slid within barrel slots 13 and 14, respectively, to compensate for axial and angular misalignments of up to k .12m and f 6.3 mili-radians. Coil spring 12 surrounding intermediate shaft 6 is held in place by front and rear spring retainers 16 and 17, respectively, providing a positive bias for engagement. Driven coupling barrel 5 has ramps 15 on its inboard end to facilitate engagement with biased intermediate shaft 6, when driven assembly 5 is engaged.
