Abstract
Description
Technical Field
[0001] The present application relates to a highly sealed gearbox housing. Background Art
[0002] The gearbox is also called a transmission. It is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in a fixed or step-by-step manner. The transmission consists of a speed transmission mechanism and an operating mechanism. A transmission housing is generally installed outside the transmission. The main function of the transmission housing is to support each transmission shaft, ensure the center distance and parallelism between the shafts, and ensure the correct installation of the transmission housing components and other components connected to it.
[0003] In order to reduce the wear of parts and power loss caused by internal friction, lubricating oil must be injected into the gearbox housing, and splash lubrication is used to lubricate the working surfaces of various gear pairs, shafts, bearings and other parts. In order to prevent oil leakage, the gearbox housing and the gearbox connection will be sealed, but the common sealing method is to install a sealing ring or apply sealant at the connection. The position of the sealing ring is fixed. When the bolts on the gearbox housing are loose, the sealing ring will also be loose, and leakage will occur immediately. After tightening the gearbox housing, the oil stains on the surface of the housing need to be cleaned, and the sealant seal will affect the disassembly of the gearbox housing.
[0004] Therefore, it is desirable to provide a highly sealed gearbox housing. Utility Model Content
[0005] In this embodiment, a high-sealing gearbox housing is provided to solve the problem that when the gearbox housing becomes loose, the sealing ring will also become loose, resulting in immediate leakage. After tightening the gearbox housing, the oil stains on the surface of the housing need to be cleaned, and the sealant seal will affect the disassembly of the gearbox housing.
[0006] According to one aspect of the present application, a high-seal gearbox housing is provided, comprising a housing body door leaf, a plurality of mounting holes being arranged at the outer end of the housing body, and a sealing ring being arranged at one side of the housing body opening; characterized in that the high-seal gearbox housing further comprises:
[0007] Telescopic structure, the side wall of one end of the shell body close to the sealing ring is provided with multiple groups of telescopic structures;
[0008] The sealing ring is fixed to the telescopic structure through the fixed structure.
[0009] Specifically, a fixing frame is fixed outside the sealing ring, and the fixing frame is consistent in size with the shell body.
[0010] Specifically, one end of the sealing ring close to the shell body extends to the outside of the fixing frame, and the outer wall of the sealing ring outside the fixing frame is slidably connected to the inner wall of the shell body.
[0011] Specifically, the telescopic structure is arranged inside the side wall of the shell body, and the telescopic structure includes an installation groove, a limit rod, a spring and a mounting plate. The side wall of one end of the shell body close to the sealing ring is provided with multiple installation grooves.
[0012] Specifically, the inner side wall of the installation groove is fixed with a limit rod and a spring, the spring is sleeved on the outside of the limit rod, the other ends of the limit rod and the spring extend to the outside of the installation groove, and the outer ends of the limit rod and the spring are fixed with a mounting plate.
[0013] Specifically, the fixing structure includes a second mounting groove, a second limiting rod, a second spring, a second mounting plate, a slot, a clamping block and a fixing plate, and the second mounting groove is symmetrically arranged at both ends of the first mounting plate.
[0014] Specifically, a fixing plate is fixed to a side wall of the fixing frame corresponding to the mounting plate 1, the mounting plate 1 is embedded in the fixing plate, and the mounting plate 1 and the fixing plate are engaged with each other.
[0015] Specifically, the inner wall of the second installation groove is fixed with a limiting rod and a spring, the second spring is sleeved on the outside of the limiting rod, and the other ends of the limiting rod and the second spring are both installed with a mounting plate.
[0016] Specifically, an end of the mounting plate 1 corresponding to the mounting plate 2 and close to the spring 1 is vertically provided with a slot, and one end of the mounting plate 2 passes through the corresponding slot and extends to the outside.
[0017] Specifically, a clamping block is fixed to one end of the second mounting plate away from the second spring, a clamping slot is provided in the fixing plate corresponding to the clamping block, and the clamping block and the clamping slot are engaged with each other.
[0018] The benefits of this application are:
[0019] 1. A telescopic structure is provided on the side wall of the shell body, and the telescopic structure is fixed to the fixed frame on the sealing ring through the fixed structure. When the gearbox shell is connected, the fixed frame is fixed to the gearbox cover, and then the shell body and the gearbox cover are fixed by bolts. When fixed, the spring 1 is compressed, so that one end of the sealing ring is slidably connected in the shell body, thereby sealing the shell body and the gearbox cover. When the shell body is loose, the sealing ring will also rebound outward under the action of the spring 1. Since the sealing ring has a movable length in the shell body, it can always play a sealing effect. When it is loose, oil leakage will not occur immediately, so there is no need to clean the shell body.
[0020] 2. By connecting the fixed frame on the sealing ring with the telescopic structure through the fixed structure, and by pressing the mounting plate 2 toward one side of the spring 1, the spring 2 can be compressed to separate the card block from the card slot, and the fixed frame can be removed, thereby disassembling the sealing ring and facilitating the replacement of the sealing ring.
