Isolator shaft transmission to signalling switches - has cam disc with levers fixed to shaft and receiving plate fixed to switch shaft

摘要

The levers are fixed to a cam disc on the shaft (2) at an angle of about 190 deg. The operating shaft of the signalling switches has a receiving plate (11) for pins (7, 8) at the lever ends. When the shaft rotates one of the pins enters into a slot (12, 13) in the plate (11) and rotates it. The transmission ratio between the cam disk and receiving plate is greater than one. The pins may be adjusted in a slot at the free end of the lever to compensate manufacturing tolerances.
