Blade is out of shape oscillating tooth gear mechanical infinitely variable speeds implement

A few days ago, company of transmission of a civilian battalion of Beijing develops a CVT successfully to be tasted newly (blade is out of shape oscillating tooth gear mechanical infinitely variable speeds implement, HN-CVT of abbreviation oscillating tooth) . Chinese machinist Cheng learns infinitely variable speeds implement point out in the attestation report of professional committee chairman Professor Zhou Youjiang in oscillating tooth HN-CVT, this transmission realized real significance to go up " type of clench the teeth infinitely variable speeds " , belong to brand-new notional high-power is efficient and mechanical infinitely variable speeds implement, the innovation that is pair of traditional gearshift theory is outspread. After Wang Shengtang of secretary-general of society of Chinese gear major has seen prototype, say, the change of this kind of structure, will from go up at all solve power of automatic transmission drive the issue with small, small efficiency. Current, CVT product basically applies on lesser power car, and oscillating tooth HN-CVT carries metal tape of synchronous tooth form and drill dish on can change continuously unit of diameter clench the teeth, the tendency drive of will traditional CVT turns into drive of tine clench the teeth, improved CVT drive power and efficiency greatly thereby, have high speed nicety not to have physical characteristic of pulsatile constant power. Although a few infinitely variable speeds that limousine car place uses implement already represented current international most advanced technique level, but still belong to awl dish style of pressurization attrition drawing drive of infinitely variable speeds, fail to break through traditional infinitely variable speeds truly implement congenital technology protective screen. The power index of the 3rd acting prototype had exceeded oscillating tooth HN-CVT international index double above. The principle prototype of oscillating tooth HN-CVT has been in Beijing international car was exhibited 2006 on appear, having trial production now. CNC Milling
