Abstract
Description
Technical Field
[0001] This utility model relates to the field of sprocket shaft assembly technology, and in particular to a testing device for sprocket shaft assemblies. Background Technology
[0002] The sprocket shaft assembly is a core component driving the chain movement in fully mechanized coal mining equipment. It is widely used in scraper conveyors, transfer conveyors, and other similar equipment. As the head / tail drive core of scraper conveyors and transfer conveyors, it undertakes the critical tasks of power transmission and material transport. The performance of the sprocket shaft assembly directly affects the operation of the entire scraper conveyor system; therefore, performance testing of the shaft assembly is extremely important.
[0003] Existing sprocket assembly testing typically employs a test bench. The sprocket assembly is mounted on the bench and rotated using a motor or other transmission device. Since the sprocket assembly is internally lubricated, rotation is used to detect oil leaks. However, in actual testing, the following drawbacks have been observed: First, the need for clamps or brackets to secure the sprocket assembly makes installation and disassembly inconvenient. Second, during rotation testing, excessive oil leakage sometimes occurs, and at high speeds, oil can splash out, contaminating the working environment.
[0004] Therefore, it is necessary to propose a testing device for sprocket shaft assemblies to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to address the issues of inconvenient disassembly and potential oil leakage and splashing that could contaminate the working environment in the existing sprocket shaft assembly testing process, and to propose a new testing device for sprocket shaft assemblies.
[0006] To solve the above-mentioned technical problems, this utility model provides a testing device for sprocket shaft assemblies, including: a wall platform, a functional groove on the front side wall of the wall platform, a transmission device installed in the functional groove, a support platform on the lower side outside the functional groove, two support frames fixedly spaced on the support platform, the sprocket shaft assembly being installed on the two support frames, its outer wall being close to the front side wall of the wall platform, the transmission device being connected to the sprocket shaft assembly via a transmission belt, a connecting frame on the upper side outside the functional groove, the connecting frame being hinged to an arc-shaped cover, the arc-shaped cover being installed on the outside of the sprocket shaft assembly, its bottom end abutting against the support platform, the arc-shaped cover having two sets of upper and lower symmetrically arranged upper and lower latches, upper and lower latches being detachably inserted into the upper and lower latches respectively, the upper and lower latches being located separately on the upper and lower sides of the sprocket shaft assembly.
[0007] In a preferred embodiment of this solution, the transmission device includes a motor, which is fixed in the functional slot. The output shaft of the motor is connected to the rotating wheel, and one end of the transmission belt is sleeved on the rotating wheel and the other end is sleeved on the sprocket shaft assembly.
[0008] In a preferred embodiment of this solution, the support frame includes a support rod and an arc-shaped frame, the arc-shaped frame being fixed to the top of the support rod, and the support rod being fixed to the support platform.
[0009] Implementing this utility model has the following beneficial effects:
[0010] The testing device for this sprocket shaft assembly uses a support frame, a wall platform, an upper clamping bracket, and a lower clamping bracket of an arc-shaped cover to enclose and fix the sprocket shaft assembly. When testing is required, simply place the sprocket shaft assembly on the support frame and secure it using the wall platform and the upper and lower clamping brackets of the arc-shaped cover. Assembly and disassembly are both convenient. Furthermore, the arc-shaped cover prevents oil leakage from the sprocket shaft assembly from splashing during testing, making it more environmentally friendly. Attached Figure Description
