Description

Technical Field

[0001] The invention relates to the technical field of gear assembly, in particular to a tool for assembling gears. Background Art

[0002] Gears are wheel-shaped mechanical parts that rely on the meshing of teeth to transmit torque. Gears can achieve functions such as changing speed and torque, changing movement direction and changing movement form by transmitting with other toothed mechanical parts. Due to the advantages of high transmission efficiency, accurate transmission ratio and large power range, gear mechanisms are widely used in industrial products. Their design and manufacturing level directly affects the quality of industrial products. Gear teeth interlock with each other, which will drive another gear to rotate to transmit power. The two gears can be separated, and chains, tracks and belts can be used to drive the gears on both sides to transmit power. With the development of the times and technology, the advancement of science and technology has also promoted the technological advancement of gear assembly tooling.

[0003] For example, the Chinese patent with the publication number "CN209035916U" discloses "a gear assembly tool", whose main structure includes a gear mounting seat, a second hydraulic cylinder, a U-shaped guide rail, a latch push rod, a clamping block, a latch through hole, a latch installation slot and a latch. The gear assembly tool, through the second hydraulic cylinder, pushes the latch push rod to move through the latch through hole provided on the clamping block, and pushes the latch in the latch installation slot into the latch hole of the gear on the gear mounting seat for fixing, avoiding the traditional manual latch fixing of the gear, greatly improving the efficiency of the gear latch fixing, and facilitating the gear assembly tool to achieve the purpose of high latch fixing efficiency.

[0004] Obviously, the above-mentioned gear assembly tool can only assemble gears in the external environment. For places where real-time installation is required inside the box, the above-mentioned gear assembly tool cannot be used, resulting in a large limitation of its use place. Manual assembly is performed using a hammer and an iron rod. The hollow end of the iron rod is put on the upper end face of the gear, and then the hammer is used to knock it, so that the gear is knocked into the shaft body to achieve assembly between the gear and the shaft body. However, this method consumes a lot of manpower and has a relatively low work efficiency. Summary of the invention
