Transmission mechanism of winch

Abstract

The invention provides a transmission mechanism of a winch. The transmission mechanism comprises a left shell, a right shell, a motor, a hollow winding drum, a left support plate, a right support plate, a short shaft, a long shaft and a speed reduction assembly; the short shaft penetrates the left support plate, and the outer end of the short shaft is connected with a left gear; the left gear is in power connection with an output shaft of the motor; the long shaft penetrates the right support plate; the inner end of the long shaft and the inner end of the short shaft are located in the winding drum and are in power connection through a shaft connecting sleeve; the speed reduction assembly comprises an auxiliary shaft, a right gear, a brake gear, a ratchet wheel and a spline hole shaft; the outer end of the long shaft is provided with a spline engaged with the brake gear; the auxiliary shaft is sleeved with the ratchet wheel, and the ratchet wheel freely rotates; the right shell is connected with a pawl abutting against the ratchet wheel; the auxiliary shaft is sleeved with the brake gear, and the brake gear and the auxiliary shaft are in threaded connection; the inner end of the auxiliary shaft is provided with a spline engaged with the right gear; the spline hole shaft is sleeved with the right gear, and the right gear and the spline hole shaft synchronously rotate; and the inner end of the spline hole shaft stretches into the winding drum, and the spline hole shaft and the winding drum synchronously rotate. The long shaft and the short shaft are hidden in the winding drum, the structure is compact, layout is reasonable, and the occupied space is small.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and relates to a transmission mechanism of a winch. Background technique [0002] Hoist, also known as winch, is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. It can lift heavy objects vertically, horizontally or obliquely. At present, the electric hoist is the main one, which can be used alone or as a component in machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large amount of winding rope, and convenient displacement. Widely used in industrial and mining, metallurgy, lifting, construction, chemical, road and bridge, hydropower installation and other lifting industries. [0003] The transmission mechanism of the traditional hoist is complicated, such as the transmission structure of the hoist disclosed in the Chinese invention patent [Patent No. CN2019211...

AI Technical Summary

Problems solved by technology

It can be seen that the above-mentioned transmission mechanism has many gears, and worms and screws are also provided, which leads to many and complicated parts and takes up a lot of space
