A winch clutch with wear compensation function and using method thereof

Abstract

The invention relates to a winch clutch with a wear compensation function and a using method of the winch clutch. The winch clutch comprises a decelerator main shaft and a roller, wherein the decelerator main shaft extends to the middle part of the roller; a plurality of mobile friction plates are uniformly fixed on the outer side of the decelerator main shaft; static friction plates arranged alternatively with the mobile friction plates are uniformly fixed on the inner cycle side wall of the roller; an oil cylinder fixedly connected with the roller is arranged on one side of the decelerator main shaft; a piston capable of axially sliding along the decelerator main shaft is arranged between the oil cylinder and the static friction plates or the mobile friction plates; a pressurizing space communicated with an external oil inlet passage is formed between the piston and the oil cylinder; the piston is connected with the end face of the decelerator main shaft by a spring. The winch clutch with the wear compensation function disclosed by the invention is simple and reliable in structure and convenient to use; the wear of the friction plates can be compensated at any time within the stroke range of the oil cylinder; the size of pressing force can be changed through controlling the size of an oil feed pressure.

Description

Technical field [0001] The invention relates to the field of clutches for winches, in particular to a winch clutch with wear compensation function and a method of use thereof. Background technique [0002] Winch, a light and small lifting device that uses a drum to wind a steel wire rope or chain to lift or haul heavy objects, also known as a hoist. The winch can be used alone or as a component of machinery such as lifting, road building and mine hoisting. It is widely used because of its simple operation, large rope winding volume and convenient displacement. Mainly used in construction, water conservancy projects, forestry, mines, docks, etc. for material lifting or flat towing. [0003] In the traditional structure, the compression force between the dynamic friction plate and the static friction plate of the winch is mostly produced by the way of compaction by a disc spring. When clutching is required, the hydraulic oil cylinder enters the oil to pull the spring and release the...

AI Technical Summary

Problems solved by technology

Since the spring pressure has been set at the initial assembly, but after a long time of use, the friction plate wears out, and there is a gap between the dynamic and static friction plates, which cannot be compensated, and the spring pressing force gradually decreases. Finally, due to insufficient pressing force, the friction The friction force of the sheet is not enough to overcome the torque generated by the load, so it is easy to slip when the winch is working

At this time, it is necessary to dismantle the whole machine, replace the friction plate, and adjust the spring pressure. The service life of the whole machine is not high, and it is time-consuming and labor-intensive.
