TECHNICAL FIELD

[0001] The utility model relates to gear box bearing structure structure and other related technical fields, especially a new type bearing sleeve structure for gear box. BACKGROUND

[0002] At present, two bosses are arranged outside the two ends of the bearing bush in the gear box, and then the bearing bush is buckled on the box body through the two bosses, but this way is troublesome to install the bearing bush and the box body together. UTILITY MODEL CONTENTS

[0003] Therefore, in order to solve the above problems, the utility model provides a new type bearing sleeve structure for gear box, which comprises:

[0004] The box body, the bearing bush, the shaft and the bearing are arranged.

[0005] The inner wall of the box body is provided with a groove in the circumferential direction, the outer wall of the bearing bush is provided with a boss in the circumferential direction, the box body is installed on the bearing bush, and the groove is matched with the boss.

[0006] The bearing is installed in the interior of the bearing bush.

[0007] The shaft is installed in the interior of the bearing.

[0008] The boss is away from the two ends of the bearing bush.

[0009] The boss is close to one end of the bearing bush.

[0010] The longitudinal section of the boss is rectangular or trapezoidal.

[0011] The longitudinal section of the groove is rectangular or trapezoidal.

[0012] The above technical scheme has the following advantages compared with the prior art:

[0013] 1. The device is simple and concise, so that the overall processing time is effectively shortened when the box body and the bearing bush are processed, the production efficiency is significantly improved, and the processing time in the production cost is reduced.

[0014] 2. The bearing bushing of this device can be firmly fixed axially to the housing. This fixing method is not only simple, but also better ensures that the bearing bushing remains in the correct axial position during the operation of the housing. This avoids problems such as accelerated wear of components and equipment failure caused by axial displacement, thereby extending the service life of the equipment and enhancing the stability of equipment operation.

[0015] 3. The fixing method of this device makes the entire gearbox more stable during operation. This stable operating state helps to reduce the occurrence of loosening and damage of parts caused by vibration, shaking and other factors. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of a novel bearing sleeve structure for a gearbox according to the present invention.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] The structures, proportions, and sizes illustrated in the accompanying drawings are solely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0020] like Figure 1 As shown, a novel bearing bushing structure for a gearbox according to a preferred embodiment is illustrated, comprising: a housing 1, a bearing bushing 2, a shaft 4, and a bearing 3.

[0021] The inner wall of the housing 1 is provided with a groove 6 in the circumferential direction, and the outer wall of the bearing bushing 2 is provided with a boss 5 in the circumferential direction. The housing 1 is installed on the bearing bushing 2, and the groove 6 matches the boss 5. The bearing 3 is installed inside the bearing bushing 2. The shaft 4 is installed inside the bearing 3.

[0022] In actual use, a boss 5 is arranged on the outer wall of the bearing bush 2 in the axial direction, and a groove 6 is arranged on the box 1 in the corresponding position, so that the bearing bush 2 can be stably fixed on the box 1 in the axial direction. This fixing method is not only simple, but also can better ensure that the bearing bush 2 remains in the correct axial position during the operation of the box 1, thereby avoiding problems such as accelerated wear of parts and equipment failure caused by axial displacement, thereby prolonging the service life of the equipment and enhancing the stability of the equipment operation.

[0023] The utility model further has the following implementation modes on the basis of the above:

[0024] Further, a novel bearing sleeve structure for a gear box, wherein the boss 5 is a certain distance from both ends of the bearing bush 2.

[0025] Further, a novel bearing sleeve structure for a gear box, wherein the boss 5 is close to one end of the bearing bush 2. Specifically, in the present device, the boss 5 is close to the lower end of the bearing bush 2.

[0026] Further, a novel bearing sleeve structure for a gear box, wherein the longitudinal section of the boss 5 is rectangular or trapezoidal.

[0027] Further, a novel bearing sleeve structure for a gear box, wherein the longitudinal section of the groove 6 is rectangular or trapezoidal. Specifically, the shape of the groove 6 is matched with the shape of the boss 5, so that the bearing bush 2 can be fixed on the box 1 in the axial direction.

[0028] The above is only the preferred embodiment of the utility model, and does not limit the implementation mode and protection scope of the utility model. For those skilled in the art, it should be realized that any equivalent replacement and obvious change obtained by applying the contents of the utility model specification and drawings should be included in the protection scope of the utility model.
