Abstract
A torque limiter includes an input shaft connected to a driving source, an output shaft connected to a driven load, a shaft sleeve, and an adjustment mechanism. The input shaft includes a positioning post. The output shaft includes a resisting post. The shaft sleeve includes a cam surface and a resisting surface, and defines a cam groove in a periphery. When the driven load is in a predetermined torque range, the positioning post is engaged in the cam groove, the output shaft is rotated by the input shaft and drives the driven load. When the driven load reaches overload torque amount, the cam surface moves relative to the resisting post, the cam surface is separated from the resisting post, such that the input shaft is separated from the output shaft. Thus, the output shaft and the driven load are protected from damaged by torque overload.
