Abstract
A torque transmission control device, coupling belleville springs which sandwich friction discs interposed between plural input discs and output discs in a housing. These members are pressed together by a friction adjustment screw set in a desired position to prevent a drive torque, exceeding a predetermined value, from being transmitted from an input to an output. A cap is provided with a rotation limiting opening to fit a protrusion on the friction adjustment screw and with stopper recesses for engaging protrusions formed on the housing to prevent the friction adjustment screw from rotating relative to the housing. This ensures that the predetermined torque value adjusted by the friction adjustment screw does not change during use.

A torque transmission device comprising
- coaxial rotatable input and output members interconnected by a torque transmitting clutch resiliently biased into engagement to transmit torque from the input to the output member, means for adjusting the resilient bias of the clutch to limit maximum torque transmission by the clutch to an adjustable desired maximum value and releasable retaining means for retaining a desired maximum torque transmission limit during the transmission of torque from the input to the output member;
- a housing having a first end and a second end, the first end defining a cylindrical cavity with the output member therein and means at the second end for connection to a rotary power source;
- wherein the means for adjusting the resilient bias of the clutch to limit maximum torque transmission to a desired maximum value is a pressure adjusting member located in the opening of the housing;
- the pressure adjusting member has a bore which accommodates the output member;
- and
- the pressure adjusting member has an axial projection extending outwardly from the housing with the bore extending therethrough.
A torque transmission device comprising:
- coaxial rotatable input and output members interconnected by a torque transmitting clutch resiliently biased into engagement to transmit torque from said input to said output member;
- a housing having a first end and a second end, said first end defining a cylindrical cavity with said output member therein and means at said second end for connection to a rotary power source;
- a pressure adjusting member, located in the opening of said housing, for adjusting the resilient bias of the clutch to limit maximum torque transmission by said clutch to an adjustable desired maximum value, said clutch comprising at least one friction disc interposed between a plurality of input and output discs, and each disc having a central bore and being positioned coaxially with said output member within the cavity, and belleville springs being axially positioned along said output shaft so as to sandwich said plurality of dics between then;
- releasable retaining means for retaining a desired maximum torque transmission limit during the transmission of torque from said input to said output member;
- said pressure adjusting member having an external screw thread which engages a corresponding thread in said housing to provide said adjustment;
- and
- said pressure adjusting member further having a bore, which accommodates said output member, and an axial projection extending outwardly from said housing with said bore extending therethrough.
