Description

Technical Field

[0001] This invention relates to bearing housings, specifically an end bearing housing and its mounting structure. Background Technology

[0002] Railway grain hopper cars are specifically designed for transporting bulk grain. The top of the car has a loading port, and the lower part of the car is funnel-shaped.

[0003] Traditional roof opening and closing mechanisms have drive shafts located outside the vehicle body. To adapt to the new roof opening and closing mechanism with the drive shaft located inside the vehicle body, and to achieve rain and dust protection at the location where the drive shaft passes through the vehicle body, a sealing end bearing seat is required.

[0004] The existing end bearing housings cannot meet the requirements for dust prevention and sealing. Summary of the Invention

[0005] The purpose of this invention is to provide an end bearing housing and its mounting structure, which solves the problem that existing end bearing housings cannot meet the requirements for dust prevention and sealing.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An end bearing housing includes a housing body and an end cover. The housing body is connected to the end cover, and a bearing is engaged between the housing body and the end cover. A bushing is provided between the bearing, and the bushing and the bearing are located in a mounting groove in the housing body. The housing body, bearing, bushing, and end cover form a labyrinth structure, achieving a sealed isolation between the inside and outside of the bearing housing, thus achieving waterproof and dustproof effects.

[0008] Furthermore, the seat body is connected to the end cover by screws, facilitating the assembly and disassembly of the seat body and the end cover. During installation, the bearing and shaft sleeve need to be installed into the seat body first, and then the end cover is installed to secure the bearing.

[0009] Furthermore, the connecting end face of the seat body is provided with a sealing gasket, which is used to seal and block the gap at the connecting end face.

[0010] Furthermore, the sealing gasket is a rubber gasket, which has the advantages of pressure resistance and good elasticity. Similarly, the sealing gasket can also be made of other materials.

[0011] Furthermore, the seat body is provided with an inner sidewall protrusion, and the inner end face of the end cover is provided with an end cover protrusion. Both the inner sidewall protrusion and the end cover protrusion fit against the side of the bearing, and the bearing is secured by the protrusion structure.

[0012] Furthermore, a bearing is provided on both sides of the bushing.

[0013] Furthermore, the bearing is equipped with a sealing ring, which can further improve the axial sealing performance.

[0014] Furthermore, the bearing is a deep groove ball bearing.

[0015] An installation structure for the aforementioned end bearing housing includes an end wall, a housing body connected to the end wall, and a bearing mounted on a drive shaft. The end wall is used to install and fix the housing body, allowing the drive shaft to extend into the end wall.

[0016] Furthermore, the seat body is connected to the end wall by bolts, which facilitates the assembly and disassembly of the seat body and the end wall.

[0017] Furthermore, a sealing gasket is provided between the seat body and the end wall.

[0018] The beneficial effects of this invention are:

[0019] 1. The labyrinth structure formed by the bearing body, end cover, bearing, and bushing improves the sealing performance of the bearing body and prevents dust and rainwater from entering the bearing housing, thus effectively preventing dust and rainwater from entering the bearing housing.

[0020] 2. Using deep groove ball bearings with sealing rings can prevent dust and rainwater from entering the bearing through the shaft end, effectively preventing dust and rainwater from entering the bearing.

[0021] 3. A sealing rubber gasket is used between the end wall and the bearing body to prevent rainwater and dust from entering the vehicle interior through the gap between the end wall and the bearing housing.

[0022] 4. The above three measures effectively prevent dust and rainwater from entering the vehicle interior, thus preventing food contamination.

[0023] The aforementioned main solution of the present invention and its various further alternative solutions can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed by the present invention; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding the solution of the present invention, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected by the present invention, and will not be exhaustively listed here.

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] Example 1

[0029] refer to Figure 1 and Figure 2 As shown, an end bearing housing includes a housing body 1 and an end cover 2. The housing body 1 is connected to the end cover 2 by screws, facilitating flexible assembly and disassembly between the housing body 1 and the end cover 2. A bushing 4 and a bearing 5 are provided in the mounting groove at the center of the housing body 1.

[0030] The inner sidewall protrusion 11 is integrally machined inside the seat body 1, and the end cover protrusion 12 is integrally machined on the inner end face of the end cover 2. Both the inner sidewall protrusion 11 and the end cover protrusion 12 fit against the side of the bearing 5, so as to realize the engagement of the bearing 5 between the seat body 1 and the end cover 2.

[0031] A bushing 4 is provided between the two bearings 5. The bearing is a deep groove ball bearing with contact rubber seals at both ends. The inner side wall of the housing body and the bearing, the bushing and the bearing, and the bearing and the end cover protrusion form a labyrinth structure to prevent dust and rainwater from entering the bearing housing through the shaft end, thereby effectively preventing dust and rainwater from entering the vehicle interior.

[0032] The connecting end face of the seat body 1 is provided with a sealing gasket, which is a rubber gasket 3, to ensure the sealing of the gap between the seat body and the end wall.
