The invention relates to the test equipment field of components of an automobile speed changer, more particularly to a rapid test and running-in system for a flexible driving element utilized by a buncher. According to the invention, a problem on low productivity can be solved, wherein the low productivity is caused by tedious installation of a metal tape or a driving chain product of a buncher during testing and running-in processes and long loading and unloading periods of workpieces during the testing and running-in processes. Four conical disc shafts are installed on a rack of the system; that is, the shafts of conical discs are installed on the rack; besides, each the two shafts are arranged coaxially; conical surfaces on the conical disc shafts are opposite to each other; and the coaxial conical disc shafts are connected though a key or in a special-shaped shaft-hole connection. Moreover, the coaxial conical disc shafts are connected by a ball key having a retainer through a ball; each pair of coaxial conical disc shafts is respectively engaged with a conical disc or a conical disc shaft through one or a set of coaxial gears, so that it can be ensured that each the two conical disc shafts make synchronized rotations; and between each the pair of coaxial conical disc shafts, at least one conical disc shaft is connected with a hydraulic cylinder that is capable of carrying out reciprocated driving movements at an axial direction. According to the invention, the system is mainly applied to production and a test of a metal tape or a driving chain, wherein the metal tape or the driving chain are utilized by a buncher.
Description
Technical field: [0001] The invention relates to the field of testing equipment for automotive transmission components, in particular to a fast test run-in system for flexible transmission elements used in continuously variable transmissions. It is mainly used in the production and testing of metal belts or transmission chains for continuously variable transmissions. Background technique: [0002] Cone-disk continuously variable transmissions are widely used in vehicles, construction machinery, agricultural machinery, power generation equipment and other industrial fields, and metal belt continuously variable transmissions are most widely used in the automotive field. The metal belt, the core transmission part, is a flexible metal closed-loop element with high tensile strength. [0003] In the research and development and production of metal strips, testing and running-in are important links to ensure quality and working life. However, due to the closed-loop geometric chara...
