A torque limit for interconnecton with a pair of coaxial shafts includes a stack of friction and separator discs alternately splined to drive shaft and to a housing affixed to a driven shaft. In a first embodiment, an annular ring receives a plurality of spring pistons for forcefully engaging the discs with each other. An inner separator disc is secured to an end of the drive shaft and an end plate is fixedly secured to the housing, such plates being in frictional contacting engagement with each other. With the inner disc being affixed to the drive shaft, restricted from both lateral and radial movement with respect thereto, bearing and spline corrosion and wear is minimized such that repair and maintenance costs are significantly reduced. In another embodiment, the discs are interposed between a pair of end plates fixed to an input hub. A bearing is interposed between one such end plate and an end plate of the output hub. The end plate of the output hub is fixedly secured to a stationary end friction plate. A plurality of torque pins interconnect the pair of end plates of the input hub and interconnect separator plates of the disc stack. A plurality of spring cup assemblies within the disc stack define the characteristic break away torque.

A torque limiter, comprising: a first shaft having a housing fixedly attached thereto; a second shaft; a stack of friction and separator discs alternately connected to said housing and said second shaft, said friction discs being axially movable with respect to said second shaft, but radially restrained; an annular ring received upon a first b earing on said second shaft at a first end of said stack of discs, said annular ring maintaining piston means forcefully engaging said first end of said stack and urging said discs into frictional contacting engagement with each other; a first plate fixedly secured to said second shaft at a second end of said stack, said piston means urging said stack onto said first plate; and an end plate secured to said housing and received upon a second bearing interposed between said end plate and said first plate.
