a winch

Abstract

The invention discloses a winch, a motor, a transmission shaft, a drum and a gear box. The drum includes: a pipe part and a connecting part; the winch also includes: a first inner bearing and a second inner bearing, and the first inner bearing and the second inner bearing The inner bearings are respectively arranged to extrude the bearing inner holes connected to the transmission shaft; the winch also includes: 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, and the gear The fitting end of the box is pressed against the outside of the first outer bearing, the inner side of the second outer bearing is squeezed on the outer wall of the pipe part and the end edge of the opening end of the pipe part, and the fitting end of the motor is pressed against and connected to the second outer bearing. outside. The winch implementing the present invention can enhance the waterproof sealing of the motor and the gearbox, improve the performance of the equipment; enhance the connectivity of the motor, the drum and the gearbox, reduce the pressure on the motor and the gearbox, and improve efficiency.

Description

Technical field [0001] The invention relates to the field of outdoor first aid equipment, in particular to a winch. Background technique [0002] The winches in the prior art mainly have 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-mentioned problems occur, the user must remove the entire winch from the car, and then remove the entire winch, then disassemble the gear and clean the impurities and old lubrican...

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
