Winch

Abstract

The invention discloses a winch. The winch comprises a motor, a transmission shaft, a drum wheel and a gearbox. The drum wheel comprises a pipe part and a connecting part. The winch further comprises a first inner bearing and a second inner bearing. The first inner bearing and the second inner bearing are provided with bearing inner holes respectively, wherein the bearing inner holes are connected to the transmission shaft in an extruding manner. The winch further comprises a first outer bearing and a second outer bearing, wherein the inner side of the first outer bearing is extruded on the outer wall of the pipe part, the assembling end of the gearbox is connected to the outer side of the first outer bearing in an abutting and pressing manner, the inner side of the second outer bearing is extruded on the outer wall of the pipe part and the end edge of the opening end of the pipe part, and the assembling end of the motor is connected to the outer side of the second outer bearing in an abutting and pressing manner. By means of the winch, the waterproof sealing performance of the motor and the gearbox can be improved, and equipment performance is improved; connecting performance of the motor, the drum wheel and the gearbox is improved, the pressure of the motor and the gearbox is relieved, and efficiency is improved.

Description

Technical field [0001] The invention relates to the field of outdoor first aid equipment, in particular to a winch. Background technique [0002] The winch in the prior art mainly has the following defects: [0003] 1. The lubricating gear in the winch is generally solid lubricating oil. Because the gear of the winch will move the lubricating oil to the side during operation, it will cause insufficient lubricating oil on the gear, causing the gear to become hot, affecting the performance and life of the equipment. [0004] 2. When the user uses the winch in an outdoor off-road environment, there will definitely be mud, mud, sand and other debris. These debris can easily enter the gear, stick to the lubricating oil, or enter the motor, affecting the performance of the equipment. [0005] 3. When the above problems occur, the user must remove the entire winch from the car, and then disassemble the entire winch, then disassemble the gear and clean the impurities and old lubricant with d...

AI Technical Summary

Problems solved by technology

[0003] 1. The lubricating gear in the winch is generally solid lubricating oil. Since the gear of the winch will drive the lubricating oil to move to the side during operation, it will cause insufficient lubricating oil on the gear, causing the gear to become hot, affecting the performance and life of the equipment

[0004] 2. When the user uses the winch in the outdoor off-road environment, there will definitely be muddy water, mud and sand and other debris

These debris can easily enter the inside of the gear, stick to the lubricating oil, or enter the motor, affecting the performance of the equipment

[0005] 3. When the above problems occur, the user needs to disassemble the whole winch from the car, and then disassemble the whole winch, then disassemble the gears, clean the impurities and old lubricant with diesel oil, and then apply new ones. Lubricant, and finally the whole winch can be reassembled and loaded into the car

It is cumbersome to replace the lubricant in the existing winch structure, and the factory usually does not recommend the user to disassemble the winch, and the maintenance cost is also high

[0006] 4. The transmission shaft will shake in the gearbox, which will increase the pressure on the motor and the gearbox, and the gear will rotate with the direction of the transmission shaft, which will affect the efficiency of the gear
