Shaft with universal joint for drive of farm machinery - has fork with end sections having cross-piece mounted and drive shaft connected by claw coupling

摘要

The shaft has a fork on the end of each section in between which a crosspiece is mounted. The fork end of the driving shaft (14) is connected to the shaft by a claw coupling (17). When the angle between driving shaft (14) and driven shaft (15) exceeds a certain angle, scales (25,26), which are mounted on the ends of the shafts, engage with one another and dis-engage the coupling (17). ADVANTAGE - The transmission of torque is interrupted when there is a danger of damage to the drive due to a large angle between the shafts.
