Embodiment Construction

[0026] The technical solutions of the present invention will be clearly and completely described below through specific embodiments in conjunction with the accompanying drawings.

[0027] refer to Figure 1 to Figure 3 , The present invention provides a silent winch, which can be used to lift or pull heavy objects by retracting and retracting steel wire ropes or chains. This application document takes the operation of retracting and retracting steel wire ropes as an example to illustrate the structure and principle of the silent winch. The silent winch includes a supporting system 10 , a transmission system 20 and a braking system 30 . The supporting system 10 is used as the supporting structure of the entire silent winch for supporting the silent winch. The transmission system 20 is arranged on the support system 10 to be operated to realize the rope receiving or releasing operation. The braking system 30 is disposed on the support system 10 and is used for braking to stop ...

Abstract

The invention provides a noiseless winch. The noiseless winch comprises a base, a transmission system and a braking system. The transmission system comprises a transmission shaft, a windlass assembly and a first gear. The transmission shaft and the windlass assembly are both arranged on the base, the first gear is connected to the transmission shaft through threads, and the first gear is engaged with the windlass assembly. The braking system comprises a second gear and third gears, the second gear is arranged on the transmission shaft in a sleeving manner and located on one side of the first gear, and a gap exists between the first gear and the second gear. The first gear and the second gear are selectively locked in an attaching manner so that rotation of the first gear and the windlass assembly can be stopped. The third gears are fixed to the base, the third gears are provided with one-way bearings, the one-way bearings are arranged on the third gears so that the third gears only can rotate in one direction, and the second gear is engaged with the third gears.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a silent winch. Background technique [0002] At present, manual winches on the market mainly include transmission shaft assemblies, pinion assemblies, pawls, ratchet assemblies, pawl shafts, torsion springs, and other components such as washers, nuts, and bolts. The pinion gear assembly is installed on the transmission shaft assembly and engaged with the ratchet assembly, so that the transmission shaft assembly can drive the pinion gear assembly and the ratchet assembly to rotate clockwise and counterclockwise. The ratchet is fixed on the ratchet shaft and can be engaged on the ratchet teeth of the ratchet assembly. During the rope receiving operation, the transmission shaft drives the pinion gear assembly and the ratchet assembly to rotate. When the ratchet assembly rotates, the pawl will engage and be inserted into the ratchet teeth of the ratchet assembly. This process will generate a lo...
