Rotary universal joint, especially for excentric screw machine.

摘要

The lubricant inlet (44) and the air outlet (54) each has a cavity (48,58) flush with each other and extending radially through the toothed ring (26,26'). It opens into a lubricant duct (50,60). Two teeth of the outer toothing (28) are removed to form lubricant ducts with a depth less than the height of the teeth in the outer toothing. The torque-transmitting couplings have an even or uneven number of teeth. The ball cup (22) is connected to an internally toothed ring by at least two adjusting springs (30).
