Recommended Torque Limiter Specifications

Torque limiters shall be a ball-detent type which transmit torque through balls retained in detents against adjustable spring pressure.

The design of the torque limiter shall be such that when torque exceeds a pre-set value the balls will leave their seats and roll free to provide complete disengagement of the driving and driven components. The device shall not incorporate friction plates, and resetting will be by a simple manual push or blow from a soft hammer with torque setting remaining constant within plus 0% to minus 10% after each disengagement and resetting.

The ball detent, as well as all parts which are heavily loaded, shall be hardened to a minimum of Rc 62. The torque limiter shall be totally enclosed and suitable for indoor/outdoor dust tight applications. With all external parts made of steel or ductile iron with suitable seals for abrasive dust environment. These parts will include hardware, module carrier plate, detent pocket plate, gear coupling and safety element modules. Release torque must be adjustable with provisions to make the adjustment tamperproof. Torque limiters will be preset by the manufacturer.

The working safety element components including plunger, detent pocket, flanged bushing and thrust races will be made of D2 steel and through hardened to Rc 62 minimum. Balls shall be of chrome-alloy steel hardened to a minimum of Rc 62. Torque limiter models submitted must have been successfully applied in mining applications for at least three years in order to be considered.

Recommended Torque Limiter Specifications

Torque limiters shall be a ball-detent type which transmit torque through balls retained in detents against adjustable spring pressure.

The design of the torque limiter shall be such that when torque exceeds a pre-set value the balls will leave their seats and roll free to provide complete disengagement of the driving and driven components. The device shall not incorporate friction plates, and resetting will be by a simple manual push or blow from a soft hammer with torque setting remaining constant within plus 0% to minus 10% after each disengagement and resetting.

The ball detent, as well as all parts which are heavily loaded, shall be hardened to a minimum of Rc 62. The torque limiter shall be totally enclosed and suitable for indoor/outdoor dust tight applications. With all external parts made of steel or ductile iron with suitable seals for abrasive dust environment. These parts will include hardware, module carrier plate, detent pocket plate, gear coupling and safety element modules. Release torque must be adjustable with provisions to make the adjustment tamperproof. Torque limiters will be preset by the manufacturer.

The working safety element components including plunger, detent pocket, flanged bushing and thrust races will be made of D2 steel and through hardened to Rc 62 minimum. Balls shall be of chrome-alloy steel hardened to a minimum of Rc 62. Torque limiter models submitted must have been successfully applied in mining applications for at least three years in order to be considered.
