Description

Technical Field

[0001] The invention belongs to the technical field of gear box production, and in particular relates to a device and method for detecting the stamping resistance of a gear box housing. Background Art

[0002] The function of the gearbox housing anti-stamping performance testing device is mainly reflected in the evaluation of the strength and durability of the gearbox housing. The gearbox housing is the installation basis of the gear transmission system, and its performance directly affects the stability of the gear transmission and the performance of the overall device. Specifically, the testing device simulates the stamping environment in actual work and applies a certain pressure to the gearbox housing to test its anti-stamping ability. In this process, key data such as the deformation of the housing under pressure, the generation of cracks, and the fracture strength can be obtained. These data are crucial for evaluating the quality and reliability of the gearbox housing. First, sufficient housing strength is a prerequisite for ensuring smooth gear transmission. If the housing strength is not enough, it is easy to crack, break, or deform and twist as a whole when under pressure, which will cause the position of the central axis of the transmission shaft to change, thereby affecting the normal meshing transmission of the gears and making the gear transmission device lose its efficiency. Secondly, through the anti-stamping performance test, the defects or deficiencies that may exist in the housing during the manufacturing or installation process can be discovered in time, so that corresponding measures can be taken to improve it. This helps to improve the overall quality and reliability of the gearbox and reduce downtime losses and maintenance costs caused by housing failure.

[0003] The existing gearbox housing anti-punching performance testing device has shortcomings when used. First, it cannot realize the rapid reset of the drop hammer; second, it cannot realize batch testing of the gearbox housing. Therefore, it is necessary to optimize and improve the existing gearbox housing anti-punching performance testing device. Summary of the invention

A sliding groove is opened at the center of the driven sprocket to facilitate the passage of the cross bar 405, and the inner wall of the sliding groove is provided with a convex key that is inserted into the keyway.

[0038] In this embodiment, the cross section of the clamping convex roller 407 is an ellipse, and the ratio of the major axis value to the minor axis value is 1.5 to 2:1.
