Adjustable over-torque protection structure for high-speed heavy-load shaft system

Abstract

The invention belongs to the technical field of mechanical transmission equipment, and particularly relates to an adjustable over-torque protection structure for a high-speed heavy-load shaft system.The adjustable over-torque protection structure comprises an outer transmission shaft system, an external connecting bearing base, an inner transmission shaft system, an adjustable over-torque protection pin assembly and an anti-flying pressure plate, wherein the outer transmission shaft system with an inner spline interface structure is connected to a high-speed heavy-load planetary gear box; theexternal connecting bearing base is connected to the box body of the gearbox; the outer transmission shaft system is connected with the inner transmission shaft system through the adjustable over-torque protection pin assembly; and the anti-flying pressure plate is connected to the inner transmission shaft system through a bolt. After the structure is adopted, the number and the structures of theover-torque protection pin assemblies are changed, so that safety, during operation and test, of a test part and a matched tester can be improved, and extreme load of safe operation can be obtained.The adjustable over-torque protection structure has the characteristics of being high in working rotation speed, compact in structure, high in universality, quick and reliable in dismounting, and effectively avoiding the test part damage risk.

Description

Technical field: [0001] The invention belongs to the technical field of mechanical transmission equipment, and in particular relates to an adjustable over-torque protection structure for a high-speed and heavy-duty shaft system. Background technique: [0002] The output shaft of a certain type of high-speed heavy-duty planetary gearbox test piece (hereinafter referred to as the test piece) has the characteristics of large transmission power (20000Kw) and high output speed (8000r / min), and the test piece is in the research and development stage, and the structural maturity is poor , so its reliability is low, resulting in low operating safety of the test piece and its supporting tester. In order to improve the safety of the test piece and the supporting tester during the running test, and to obtain the ultimate load for its safe operation, it is necessary to add a flexible structure that is easy to assemble and disassemble and has an adjustable load-carrying capacity on the t...
