Description

Technical Field

[0001] The utility model relates to the technical field of reducers, and in particular to a reducer for an industrial robot. Background Art

[0002] Industrial robot reducer is a basic mechanical transmission device widely used in industrial robots. Its main function is to match the speed and torque between the prime mover and the working machine or actuator, thereby achieving efficient and stable mechanical transmission.

[0003] Industrial robot reducers generate a lot of heat when running under high load. If this heat cannot be fully dissipated, the gear temperature will increase significantly, which may cause gear deformation. This will not only shorten the service life of the reducer, but may even cause failures and cause unnecessary losses. Summary of the Invention

[0004] The purpose of the present utility model is to provide an industrial robot reducer to overcome the above-mentioned defects in the prior art.

[0005] An industrial robot reducer includes a lower case, an upper case, and a heat dissipation assembly. One side of the lower case is rotatably connected to a rotating shaft 1, and a bevel gear 1 is mounted on the rotating shaft 1. The bevel gear 1 meshes with a bevel gear 2 on a rotating shaft 2 rotatably connected in the lower case. The rotating shaft 2 is also mounted with a bevel gear 3, and the bevel gear 3 meshes with a bevel gear 4 on a rotating shaft 3 rotatably connected in the lower case. The upper case is mounted in the lower case, and the heat dissipation assembly is arranged on the top of the upper case.

[0006] Preferably, the lower box body and the upper box body are connected by a plurality of bolts.

[0007] Preferably, the heat dissipation assembly includes a heat dissipation plate and heat dissipation fins. The heat dissipation plate is arranged on the upper box body, and a plurality of heat dissipation fins are provided and arranged in multiple rows on the heat dissipation plate.

[0008] Preferably, the distance between two adjacent heat dissipation fins in the same row is 5-10 mm.

[0009] Preferably, the heat sink is provided with arc-shaped grooves between adjacent rows of heat sink fins, and the diameter of the arc-shaped grooves is 15-25 mm.

[0010] Preferably, the heat dissipation fins are 20-35 mm in height, and the tops of the heat dissipation fins are provided with arc-shaped chamfers.

[0011] Preferably, the four corners of the heat dissipation plate are respectively provided with connecting ears, and each connecting ear is connected to the upper box body by a screw.

[0012] The beneficial effects achieved by the utility model are:

[0013] In this application, the bevel gear 1 on the shaft 1 drives the shaft 2 to rotate, and the bevel gear 3 on the shaft 2 drives the shaft 3 to rotate through the bevel gear 4 on the shaft 3, thereby reducing the rotation speed and increasing the torque. The heat generated during the operation is dissipated through the heat dissipation plate and several evenly distributed heat dissipation fins on the heat dissipation component, thereby improving the life of the reducer. At the same time, the heat dissipation component is installed on the reducer in a detachable manner, thereby facilitating the disassembly and assembly of the heat dissipation component.
