[0002] A gearbox is an important transmission device widely used in the mechanical field. Its core function is to change the speed and transmit torque through the meshing of gears with different numbers of teeth. During operation, the power input shaft drives the driving gear to rotate, and the driving gear meshes with the driven gear, thereby transmitting power and adjusting the speed. Gearboxes have many advantages; they can convert high-speed, low-torque power into low-speed, high-torque power according to actual needs, to meet the working requirements of different mechanical equipment.

[0003] The gearbox housing is a key component of the gearbox, acting like a robust "protective shield." Its main function is to house and protect internal transmission components such as gears, shafts, and bearings, providing them with a stable working environment. Existing gearbox housings, to ensure their sealing and structural strength, often use a large number of bolts to assemble and fix different parts of the housing, and some housings are designed as a single piece. This makes disassembling and opening the gearbox housing cumbersome and complex, resulting in difficulties in opening the housing during maintenance, increasing maintenance complexity and affecting maintenance efficiency.

[0004] Therefore, a detachable gearbox housing is needed to solve the problems mentioned in the background art. Utility Model Content

[0010] As a preferred embodiment, the rubber pad is arranged in the groove.

[0011] As a preferred embodiment, two rubber pads are arranged symmetrically.

[0012] Compared with the prior art, the detachable gear box shell has at least the following beneficial effects:

[0013] The adjusting assembly is used to press a certain amount of liquid into the cavity of the rubber frame, so that the rubber frame is expanded as a whole, and then the side wall of the expanded rubber frame is tightly pressed on the four side surfaces of the cover plate, so that the cover plate is fixed in the opening end of the gear box shell, and the gap between the cover plate and the inner side wall of the gear box shell is fully sealed, so that the cover plate seals the opening end of the gear box shell, when the gear box shell needs to be maintained, the adjusting assembly is arranged to release the expansion of the rubber frame, so that the cover plate can be easily removed from the opening end of the gear box shell, so that the opening end of the gear box shell is opened, and the inside of the gear box shell is maintained, and the cover plate is removed, and the plurality of screws are repeatedly assembled and disassembled, so that the sealing and covering efficiency of the cover plate is improved, and the subsequent maintenance is facilitated.
