[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine, and plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator.

[0003] The existing rigid shell includes an upper shell and a lower shell, which are usually assembled into a box body. When assembling the box body, an external lifting device is used to lift the upper shell to the top of the lower shell and assemble it with multiple bolts;

[0004] During the use of the reducer case, the transmission shaft on the gear reducer rotates for a long time in the case and will continue to generate vibration, causing multiple bolts between the upper shell and the lower shell to be subjected to vibration impact for a long time, which can easily cause the bolts between the upper shell and the lower shell of the case to loosen, affecting the tight installation effect of the upper shell and the lower shell. Therefore, an impact-resistant reducer case is proposed. Utility Model Content

[0012] Beneficial Effects

[0014] Beneficial effects:

[0015] The utility model is installed on the first connecting plate and the second connecting plate by means of multiple bolts and U-shaped frames. The U-shaped frame will limit the longitudinal direction of the first connecting plate and the second connecting plate, and the bolts will limit the transverse direction of the first connecting plate and the second connecting plate, which can well improve the impact resistance of the first connecting plate and the second connecting plate. Moreover, by inserting the mounting plate into the mounting groove and the limiting groove, the transverse direction of the first connecting plate can be limited again, and the card block is inserted into the card groove to limit the longitudinal direction of the first connecting plate again. By doubly supporting and limiting the longitudinal and transverse directions of the first connecting plate and the second connecting plate, the impact force of the vibration between the upper shell and the lower shell can be well reduced, and the impact force of multiple bolts on the upper shell and the lower shell can be effectively reduced, thereby ensuring the firmness of the installation of the upper shell and the lower shell.
