Abstract

The invention discloses a mechanical quantitative adjustment torque limiter, and belongs to the field of torque limiter mechanical equipment. At present, most mechanical torque limiters do not have the function of quantitatively adjusting and limiting torque according to scales, the torque setting can only be obtained through tests, and operation is inconvenient. The invention provides a mechanical quantitative adjustment torque limiter which is characterized in that an input end flange (7) is coaxially arranged in a disc body of a torque setting drive plate (1), an output shaft (3) is coaxially mounted at the position of a middle hole of the input end flange (7), an input end rolling bearing (15) is sleeved at the input end of the output shaft (3), and an output end rolling bearing (4) is sleeved at the output end of the output shaft (3); and the input end flange (7) applies or eliminates limiting torque to the output shaft (3) through each guide column (19) and the friction column (6) sleeved on the guide column (19). The limiting torque is set through simple operation, the principle is simple, complex debugging work is not needed, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to a mechanical quantitative adjustment torque limiter. Background technique [0002] The main function of the torque limiter is overload protection, also known as torque limiter, safety coupling, or safety clutch, which is a component that connects the main machine and the working machine. , it limits the torque transmitted by the transmission system in the form of slipping, and restores the connection when the overload situation disappears, thus preventing mechanical damage and costly shutdown losses. [0003] At present, most mechanical torque limiters do not have the function of quantitatively adjusting the limited torque according to the scale, and the torque setting can only be obtained through experiments, which is inconvenient to operate. In addition, there is also a torque limiter with a scale, which has many operation steps, complicated debugging process and inconvenient use. Contents of the invention [0004] The pu...
