Description

Technical Field

[0001] This utility model relates to the field of planetary carrier technology, specifically a brake planetary carrier. Background Technology

[0002] The planetary carrier is one of the main components of a planetary gear transmission. The planetary gear shafts or bearings are mounted on the planetary carrier. The structural form of the planetary carrier largely depends on its intended use, the manufacturing method, and the assembly conditions of the planetary gear reducer. A reasonable planetary carrier structure should have small external dimensions and light weight, ensuring uniform load distribution between the planetary gears and along the meshing tooth width. It should also have good machining and assembly processes, enabling the planetary gear transmission to have high load-bearing capacity and low vibration and noise. Traditional brakes often use planetary carriers that are bolted for installation. However, bolts are prone to corrosion, stripping, and damage during use due to vibration, affecting subsequent maintenance and repair. Furthermore, because they are often open, external dust and other foreign matter can easily enter the planetary carrier, affecting its use. Therefore, we propose a new type of brake planetary carrier. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a brake planetary carrier. The planetary carrier is installed by using spring contraction to insert the insert block into the insertion hole, which solves the problems of corrosion, stripping and damage that are easy to occur with traditional bolt fixing. At the same time, the cleaning brush can clean the dust and foreign objects on the surface of the planetary gear to prevent them from entering and affecting subsequent use. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a planetary carrier for a brake, comprising a base frame and a top frame;

[0005] Base frame: The top surface is uniformly fixed with fixed columns at the center, the surface of the fixed columns is provided with mounting grooves, the bottom surface of the top frame is uniformly provided with mounting blocks corresponding to the positions of the fixed columns, the mounting blocks are inserted into the mounting grooves, the surface of the top frame is uniformly provided with shaft holes at the center, the top surface of the base frame is uniformly provided with shaft grooves, and the inside of the fixed columns is provided with fixing units.

[0006] It also includes a planetary gear shaft and a planetary gear assembly. The bottom end of the planetary gear shaft is installed corresponding to the shaft groove, and the planetary gear assembly is rotatably sleeved on the outer side of the planetary gear shaft.

[0007] The mounting block is inserted into the mounting slot to install the base frame and the top frame. The planetary gear shaft is installed inside the shaft slot, and the shaft hole is locked at the top of the planetary gear shaft to increase its installation stability. The planetary gear assembly on the outside of the planetary gear shaft meshes with the external gear to facilitate the use of the subsequent brake.

[0008] Furthermore, the fixing unit includes a pull plate, a plug, a limiting plate, a handle groove, a spring, and a socket. The spring is fixed inside the mounting groove, and the outer end of the spring is connected to the inner side of the pull plate. The top of the inner side of the pull plate is provided with a plug. The limiting plate is fixed in the middle of the mounting groove. The outer side of the pull plate is provided with a handle groove. The socket is opened on the surface of the mounting block. When the pull plate is loosened, the spring retracts, allowing the plug to be inserted into the socket to solve the problems of corrosion, stripping, and damage that are common with traditional bolt fixing. The handle groove also makes it convenient for personnel to pull the pull plate during subsequent maintenance.

[0009] Furthermore, the fixing unit also includes a limiting groove, a limiting post, a locking block, and a locking slot. The limiting groove is formed on the bottom surface of the planetary gear shaft, the limiting post is fixed inside the shaft groove, and the limiting groove and the limiting post are inserted into each other. The locking block is installed on the surface of the planetary gear shaft, and the locking slot is formed inside the shaft hole at the position corresponding to the locking block. The limiting post is inserted into the limiting groove, and the locking block is engaged in the locking slot. This can lock the position of the planetary gear shaft to prevent accidental rotation during subsequent use.

[0010] Furthermore, the planetary gear assembly includes an external gear and an inner ring. The inner ring is fixed inside the external gear. The external gear is made of high-strength steel, and the inner ring is made of aluminum alloy. The high-strength steel used for the external gear enables the planetary carrier to withstand large loads and impacts, while the aluminum alloy used for the inner ring also gives it good thermal conductivity and strong corrosion resistance.

[0011] Furthermore, it also includes a T-block, a cleaning brush, and a T-slot. The T-slot is formed on the side of the fixed column. The T-block is installed on the surface of the cleaning brush. The T-block and the T-slot are slidably installed. The T-block is inserted into the T-slot to install the cleaning brush. This can clean dust and foreign objects from the surface of the rotating planetary gear to prevent them from entering and affecting subsequent use.

[0012] Furthermore, it also includes a sealing gasket, which is bonded to the top surface of the fixed column. The sealing gasket is made of rubber and can prevent loosening at the connection between the top frame and the base frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This planetary brake carrier has the following advantages:

[0014] 1. By loosening the pull plate to retract the spring, the insert block is inserted into the socket, which solves the problem of corrosion, stripping and damage that are easy to occur with traditional bolt fixing. The handle groove also makes it convenient for personnel to pull the pull plate during subsequent maintenance.
