摘要

Designers are constantly facing the challenges of packing more and more functionality into ever-smaller spaces whilst improving power and performance. Mechanical overload protection for drive train systems has long been desirable but in the past has required bulky and expensive slip clutch mechanisms. Tolerance Rings have traditionally been used to compensate for machining tolerances or differential thermal expansion effects but developments in Tolerance Ring technology outlined in this paper are enabling them to be more widely used as simple, low cost, non-destructive overload protection devices. The principles of Tolerance Ring design are outlined, along with an explanation of the factors affecting resulting design parameters such as assembly force, radial load capacity, spring compression and slip torque. Examples of successful overload protection applications are detailed, from the appliance and automotive industries.
