Lever hoist wire rope testing project

The lever hoist wire rope test project, the design of the mechanical efficiency is reflect the force transmission system quality and the manufacturing quality of a project. Lever hoist industry, this project has discussed proposed hoist equipment, measurement techniques and special test bench test method, but because of its precision is not high or testing difficulties to unity and promotion. This paper introduces a method, which can conveniently and accurately calculate the chainb lock hoist wire rope mechanical efficiency. One of the chain mechanical transmission parts. Each section by the roller chain plate, sleeve, and the shaft pin pin (chain), etc. Vice many chain transmission in drilling equipment, such as the diesel engine and car, winch drive and drive wheel, etc. Its advantage is to transfer power without sliding, under high-speed and two axis center distance can be very big. Drilling equipment used in the chain of sleeve roller chain, there are more than three row and double row row, such as mechanical upload using chain. Made of metal small ring together like a rope.
