Abstract
1376398 Breaking pieces J HOCHREUTER 25 Aug 1972 39681/72 Heading F2X A shearing pin safety coupling for connecting two shafts comprises two parts 3, 4 formed with external flanges 18, 21 having bushes 19, 26 distributed around them and axially aligned so as to hold shearing pins 20. The flange 21 has an integral annular projection member 23 overlapping the flange 18, with a facing ring 24 attached to it by screws 25. On the cylindrical inner face of the projection formed by member 23 and facing ring 24, and on the cylindrical outer face of the flange 18, there are provided bearing surfaces in the form of ball-bearing races 27, 28 of V-shaped (or, alternatively, semi-circular) cross-section which hold a set of ball bearings 29. If the shearing pins 20 break during operation due to the permissible torque being exceeded, the ball bearing comprising the races 27, 28 and the balls 29 prevents axial separation of the two coupling parts 3, 4. In addition, insofar as the balls 29 lie without play against the two pairs of inclined surfaces in the ball races 27, 28 any radial movement between the coupling parts 3, 4 is also precluded. At high rotary speeds, such movements could result in correspondingly high eccentricities and centrifugal forces. The bearing is provided with a grease or oil filling which necessitates an appropriate sealing. For this purpose, the mutually-facing end surfaces of the member 23 and the facing ring 24 are formed as an endless rabbet 30, a sealing ring in the form of a lip 31 is provided between the facing ring 24 and the flange 18, and an O-ring 32 is provided between the member 23 and the flange 18. Each coupling part is formed at its outermost end with internal toothing 1, 2 meshing with crowned outer teeth 5, 6 formed on a shaft hub 7, 8. Each hub 7, 8 has a groove 9, 10 for the reception of a plate spring to ensure positive connection with a drive shaft or driven shaft. In an alternative embodiment (Fig. 2, not shown) a similar shearing pin safety coupling is described formed as a claw coupling.
