Description

Technical Field

[0001] The utility model relates to the field of gear boxes, in particular to a gear box for a planetary gear reduction motor. Background Art

[0002] Currently, a Chinese utility model with the announcement number CN214092963U discloses a vertical planetary gearbox, which relates to the field of transmission technology. In response to the problems of existing vertical planetary gearboxes, the following solution is proposed, which includes a gearbox body, a placement opening is opened on the top outer wall of the gearbox body, mounting grooves are opened on the outer walls at both ends of the placement opening, the inner walls of the mounting grooves are threaded, a box output cover is installed on the top outer wall of the placement opening, fixing grooves are opened on the outer walls at both ends of the box output cover, and the fixing grooves are connected to fixing bolts, which are threadedly connected to the mounting grooves, a mounting hole is opened on the top outer wall of the box output cover, an output shaft is rotatably connected to the inner wall of the mounting hole, and a fixed spline groove is opened on the outer wall of the output shaft. By opening a fixed spline groove on the outer wall of the output shaft, the utility model can facilitate connection with other instruments, improve the connection between instruments, and improve efficiency. A sealing gasket is installed between the gearbox body and the box output cover to prevent leakage of lubricating oil inside the gearbox;

[0003] Although the existing gearbox can improve the side sealing effect by adding sealing gaskets, there are still other problems during use, such as the lack of exhaust and oil return function. When the internal temperature of the gearbox rises after a long period of operation, the volume of the box body remains unchanged due to gas expansion, and an exhaust port needs to be opened on the top of the box body. Although the opening of the exhaust port can balance the internal pressure, the lubricating oil in the box body is easily sprayed out from the exhaust port along with the air due to air pressure, resulting in waste of lubricating oil, poor safety, and no height adjustment function. When there is a difference between the two ends of the gearbox and the shaft after it is fixed, it is necessary to temporarily add a fixing bracket to the bottom of the box body, which is time-consuming and labor-intensive, and increases the installation burden of personnel. In order to solve the above-mentioned problems, we propose a gearbox for a planetary gear reduction motor. Utility Model Content

[0004] The utility model aims to provide a gear box of a planetary gear reduction motor, which solves the problem that the existing gear box does not have the exhaust and oil return function and the height adjustment function.

[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: a gearbox of a planetary gear reduction motor, comprising a box body, a bottom plate is provided at the bottom of the box body, a support plate is symmetrically welded on the top of the bottom plate, a threaded rod is symmetrically welded on the surface of the box body, two sliding grooves are provided inside the support plate, the other end of the threaded rod extends to the outside of the support plate and is threadedly connected with a fixing nut, a fixing seat is bolted to the surface of the box body, a first exhaust channel is provided inside the fixing seat, two through holes connected to the first exhaust channel are provided on the surface of the box body, two second exhaust channels connected to the first exhaust channel are provided on the top of the fixing seat, and a fixing cylinder is threadedly connected to the top of the second exhaust channel.

[0006] The above technical solution can provide a height adjustment function, is simple and convenient to operate, is conducive to the connection between the gearbox and the external shaft, and reduces the installation burden of personnel. At the same time, it can provide an exhaust and oil return function to avoid the internal lubricating oil from being discharged outward from the exhaust port, reducing the waste of lubricating oil and having high practicality.

[0007] The utility model is further configured as follows: a mounting hole is opened on the top of the base plate.

[0008] By adopting the above technical solution, the provision of the mounting holes makes it easy for personnel to install and fix the base plate with screws.

[0009] The utility model is further configured as follows: the threaded rod and the fixing nut are both made of stainless steel.

[0010] By adopting the above technical solution, the threaded rod and the fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0011] The utility model is further configured as follows: the box body is cast from alloy steel.

[0012] By adopting the above technical solution, the box body has good wear resistance and impact resistance.

[0013] The utility model is further configured as follows: an oil-proof and breathable membrane is bonded to the interior of the fixing cylinder.

[0014] By adopting the above technical solution, the oil-proof and breathable membrane is provided, which can not only prevent the entry of external dust, but also achieve the purpose of ventilation.

[0015] The utility model is further configured as follows: a limiting ring plate is fixedly sleeved on the surface of the fixing cylinder.

[0016] By adopting the above technical solution, the fixing tube can be limited by the provision of the limiting ring plate, thereby preventing the fixing tube from being screwed in too deeply during installation.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The utility model first fixes the base plate in the specified position with screws, and then loosens the fixing nuts with tools after the base plate is fixed. After the fixing nuts are loosened, the box body is lifted upward. When the box body moves, it drives the threaded rod and the fixing nuts to move together. When the box body is lifted to the appropriate distance, the fixing nuts can be tightened again with tools. It has a height adjustment function, is simple and convenient to operate, is conducive to the connection between the gear box and the external shaft, and reduces the installation burden of personnel;

[0019] 2. The utility model, when the internal pressure of the box is too high, the gas and the sprayed lubricating oil will enter the first exhaust channel through the through hole, and the lubricating oil will release the force and flow back into the first exhaust channel after being sprayed, while the gas will enter the second exhaust channel in a flowing state. The gas entering the second exhaust channel will be discharged to the outside through the oil-proof breathable membrane to equalize the pressure. It can have the exhaust and oil return function, avoid the internal lubricating oil from being discharged outward from the exhaust port, reduce the waste of lubricating oil, and has high practicality.
