Recently, in Chongqing development of new and high technology, the hyperboloid helix gear that senior engineer Cao Derong develops wins national patent. This product applies to the long-range drive rear wheel of of all kinds car. Compare with product photograph with current place, its sex price rises significantly than having. The tine of hyperboloid helix gear is on section hyperboloid " double Qu Luo comes back " . Hyperboloid helix gear deputy by coincide of on part double music two straight generatrix. Because its are straight bus and central line crisscross, line of 2 rounds of centers also crisscross, so, gear of double music helix can have crisscross axis drive. Current, there still is real hyperboloid gear product on the world, gear of helix of more incomparable curved surface, use extensively at the accurate hyperboloid gear of car rear drive only, not be right helix gear wheel, however curve gear or cycloidal gear. Accordingly, its create difficulty big, quality assures very hard. The hyperboloid helix gear that Cao Derong develops makes rear drive smooth and breathed, at the same time 3 tine go to clench the teeth 4 tine, suit burden, suit dynamical drive, have optimal oil the model forms a condition and but high speed, and make simple, precision tall. Contriver is special on current equipment jacket tool, development gives experimental unit, efficiency and precision are very tall. 1/3 what its produce cost to be less than accurate hyperboloid gear. The noise source of the car basically comes from gear. Current, take accurate hyperboloid positive drive advocate action point still depends on position of axle. The car needs to reduce position of axle, so that get off on people. Cross-country car needs to lift position of axle will raise cross-country sex. The production technology of gear of accurate hyperboloid helix is gotten greatly than vertebra gear difficulty much, the gear of accurate hyperboloid helix that uses on the car especially, need precision achieves clench the teeth of gear high quality, odd precision working procedure should raise 3000 yuan two cost. If use hyperboloid helix gear to replace gear of accurate hyperboloid helix to replace gear of accurate hyperboloid helix, although the 1/2 of the deputy to hyperboloid helix gear person that the cost after reaching helical gear to refine entirely also has thereinbefore only. The foreign country invests business not less to use this technology of purpose. CNC Milling
