Description

Technical Field

[0001] This utility model relates to the technical field of bearing testing devices, specifically a bearing mud testing device for bearings with protrusions on oil seal covers. Background Technology

[0002] The sealing performance of bearings is a crucial factor, especially in harsh operating environments such as mud, dust, and water. Particulate matter and moisture in these environments can easily penetrate the bearing, leading to wear and damage, thus affecting bearing performance and lifespan. Some bearings have raised oil seal caps; currently, there is no suitable mud testing device. Therefore, it is necessary to design a device specifically for testing the sealing performance and durability of bearings with raised oil seal caps in mud environments to meet current usage requirements. Utility Model Content

[0003] This invention provides a mud testing device for bearings with protruding oil seals, which can solve the problem that existing bearings with protruding oil seals cannot accurately simulate the mud environment encountered by the bearings in actual use due to the lack of matching testing devices, and thus cannot truly reflect the performance of the bearings under complex mud conditions.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mud testing device for bearings with protruding oil seal caps, comprising a base plate as a support platform for the entire testing device, ensuring the stability and safety of the device; a mud placement tank, positioned at the upper front of the base plate, used to hold mud to simulate the working state of the bearing in a mud environment, with a vertically arranged column at the rear of the mud placement tank, the column being fixedly connected to the base plate; and a bearing fixing assembly, vertically movable and positioned directly above the mud placement tank, used to place and fix the bearing to be tested, with a main shaft vertically arranged on the upper side of the bearing fixing assembly, a drive device on the upper side of the main shaft, and a mounting plate at the bottom of the drive device. A connecting flange is inserted at the rear end of the mounting plate. The connecting flange is sleeved on the column and can slide up and down along the column for adjustment. The bearing fixing assembly includes a first cover plate connected to the main shaft. An auxiliary protective cover is sleeved on the outer periphery of the first cover plate. The lower end of the auxiliary protective cover is connected to an integral cover by a first fastener. A hollow receiving cavity is provided inside the integral cover. A second cover plate is provided in the middle of the lower end of the integral cover. The receiving cavity between the first cover plate and the second cover plate is used to place the bearing. The bearing fixing assembly can firmly fix the bearing with the protrusion on the oil seal cover to prevent it from moving or falling off during the test. It can realistically simulate the working state of the bearing in the actual mud environment, thereby providing more accurate sealing performance and durability test results.

[0005] Preferably, the receiving cavity is provided with a fixing shaft for fixing the inner ring of the bearing. The fixing shaft is used to fix the inner ring of the bearing to ensure that the inner ring and the fixing shaft move together during the test.

[0006] Preferably, a mud stirring plate is detachably provided at the bottom of the second cover plate. The side of the mud stirring plate extends outward and downward. A second fastener is provided in the middle of the second cover plate. The second fastener passes through the mud stirring plate, the second cover plate, the fixed shaft and the first cover plate in sequence and is connected to the main shaft. The mud stirring plate is used to stir the mud to simulate the mud flow state in actual work. The second fastener connects the bearing fixing assembly to the main shaft.

[0007] Preferably, at least one rubber ring is provided on the outer wall of the fixed shaft, the inner wall of the overall machine cover, and the outer wall of the auxiliary protective machine cover. This design is simple and increases friction.

[0008] Preferably, a first clearance groove is provided on the lower side between the auxiliary protective cover and the first cover plate, and the first clearance groove accommodates the protruding part of the bearing oil seal cover.

[0009] Preferably, a second clearance groove is provided on the upper side between the overall cover and the second cover plate, and the second clearance groove accommodates the protruding part of the bearing oil seal cover.

[0010] Preferably, the drive device is a motor, and a speed regulator is provided on one side of the mounting plate. The speed regulator is electrically connected to the motor, the motor provides power to the bearing, and the speed regulator is used to adjust the speed of the motor.

[0011] Preferably, the base plate is provided with support feet at the four lower corners and handles at both upper ends for easy handling of the tooling.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] With its simple structure and convenient operation, this device realistically simulates the working state of bearings in actual mud environments. Its simple operation process and efficient test design enable it to quickly complete mud tests on bearings, making it suitable for rapid testing needs in large-scale production. It can solve the problem that existing bearings, due to the protrusion of the oil seal cover, lack a matching test device, making it difficult to accurately simulate the mud environment encountered by bearings in actual use and thus failing to truly reflect the performance of bearings under complex mud conditions.
