2 、當輪齒在節點嚙合時，隨著轉速或載荷的變化，齒面摩擦系數並非呈單調變化，而是存在極值點;節點嚙合處的齒面摩擦系數很小，其數量級為10一， ，因此在做齒輪強度設計時，忽略齒面摩擦力的影響是有理論根據的。The main research results are as follows : the friction contact between teeth in the tooth - locked quick closure device is studied, and the simulation is made to the contact conduct between the teeth utilizing the face to face contact model with contact element and coulomb friction model, the whole finite element model of tooth - locked quick closure device is created
