Description

Technical Field

[0001] The invention belongs to the technical field of gear box detection equipment, and in particular relates to a gear box rollover test bench. Background Art

[0002] Gearbox test benches are usually used to test and evaluate the performance and reliability of gearboxes. These test benches can simulate parameters such as load, speed, temperature under actual working conditions to ensure that the gearbox can operate normally and meet the design requirements under various working conditions. These tests usually include durability tests, load bearing capacity tests, impact load tests, etc., which help to discover potential design defects or weaknesses in advance and ensure product quality and reliability.

[0003] In the prior art, a Chinese patent with publication number "CN220863786U" discloses a gearbox test bench. The beneficial effect achieved by setting a size adjustment device on the operating table is that there is no need to change the mold. Only by adjusting the size on the test bench, gearboxes of different sizes can be tested. It is suitable for testing gearboxes of various sizes, which solves the problem that most gearbox test benches are currently limited to the type of molds and can only test gearboxes of fixed sizes. If you want to test gearboxes of different sizes, you need to manually change the mold on the test bench, which not only wastes time but also may be difficult to find a mold that matches the required gearbox.

[0004] However, the above device still has the following problems during implementation:

[0005] When the gearbox is connected to the output device, it is often equipped with a connecting flange to fix the output position and maintain the stability of the axial transmission. However, when the gearbox is docked with the output end of the output device, it is necessary to manually use hydraulic equipment to lift the gearbox and adjust the angle of the connecting flange to keep it matched. However, there is a lack of stable supporting structure during adjustment. The volume and weight of the gearbox are very heavy, and it is easy to tilt or even fall during adjustment.

[0006] To this end, we provide a gearbox flip test bench to solve the above problems. Summary of the invention
