Description

Technical Field

[0001] The utility model relates to a reducer housing, belonging to the technical field of reducers. Background Art

[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. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery, and the reducer housing is the outer shell that seals the connecting shaft inside the reducer.

[0003] There are still some problems with the existing reducer case during use. When the reducer runs for a long time, the temperature inside the reducer case will gradually increase. Since the reducer case is a closed device, the heat inside it is not easy to dissipate, which affects the normal operation of the reducer. If the heat dissipation holes are directly opened, the dust from the outside will continuously enter the interior of the case through the heat dissipation holes. At the same time, during operation, the friction between the connecting shafts will increase, and lubricant needs to be added. Utility Model Content

[0004] The purpose of the utility model is to provide a reducer case. The utility model has a simple structure and is easy to use. When high temperature is generated inside the case, the heat dissipation inside is automatically processed. When the temperature returns to normal, the heat dissipation holes are automatically blocked to prevent external dust from entering the inside of the case. Lubricant can be automatically added to the inside of the case to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Furthermore, the air inlet pipe is located inside the chassis body, and the return spring is symmetrically distributed between the moving plate and the inner wall of the operating box.

[0009] Furthermore, the heat dissipation holes are evenly distributed in the inner wall of the chassis body, and the guide rods cross the inner wall of the operating box.

[0010] Furthermore, the shielding plate is movably connected to the top of the chassis body, and the area of ​​the shielding plate is larger than the total area of ​​the heat dissipation holes.

[0011] Furthermore, the extraction pump is electrically connected to the power box through a wire, and the extrusion rod is located outside the elastic switch.

[0012] Furthermore, one end of the extraction pump away from the conduit is located at the inner bottom of the lubricant box, and the spray cover is located inside the chassis body.

[0013] The beneficial effects of the utility model are:

[0014] (I) The utility model is provided with a chassis body. When high temperature is generated inside the chassis body, the heat inside the chassis body will enter the elastic airbag inside the operating box through the air inlet pipe. At this time, the elastic airbag will expand under the action of thermal expansion and contraction, thereby pushing the movable plate inside the operating box. The movable plate drives the guide rod to move, so that the guide rod drives the shielding plate to move on the top of the chassis body. At this time, the heat dissipation holes can be leaked to dissipate heat inside the chassis body. When the temperature inside the chassis body returns to normal, the elastic airbag inside the operating box returns to normal. Under the action of the reset spring, the movable plate drives the shielding plate outside the guide rod to shield the heat dissipation holes again, thereby preventing external dust from entering the chassis body through the heat dissipation holes.

[0015] (ii) The utility model is provided with a chassis body, and a lubricant box is fixedly connected to the outside of the chassis body. When the movable plate drives the guide rod to move, the guide rod drives the extrusion rod to move. At this time, the extrusion rod will squeeze the elastic switch on the outside of the power box, so that the power box is energized. Then, the power box and the wire are used in conjunction to start the extraction pump on the outside of the lubricant box. At this time, the extraction pump will drive the lubricant in the lubricant box into the inside of the chassis body through the spray hood on the outside of the conduit, thereby lubricating the connecting shaft inside the chassis body, thereby achieving the effect of automatically adding lubricant.
