And application of automobile transmission shaft
 Hits:       Date:13-03-23
Generally include a by sliding fork and spline shaft of sliding splined, in order to realize the transmission length change. In order to reduce sliding splined shaft axial sliding resistance and wear, sometimes to spray phosphating treatment or nylon spline tooth layer; Others in the grooves in the needle roller, roller or ball bearings rolling elements, to rolling friction instead of sliding friction, improve the transmission efficiency. But this kind of structure is relatively complex, high cost. Sometimes to have a serious impact load of transmission, but also adopts flexible shaft. Splines on the transmission shaft should be lubricated and dust control measures, spline tooth gaps with keyway shoulds not be too large, and should be in accordance with the corresponding tag assembly, so as to avoid the wrong destroyed the dynamic balance of drive shaft assembly.
The shaft length and Angle and their variation range is determined by the auto layout design. Design shall ensure that the shaft length is maximum, the spline housing and shaft with sufficient length; And at length at the top the most hours not die. Shaft Angle directly affect the universal joint cross shaft and the size of the needle roller bearing, universal transmission efficiency and the life of a spider spinning inhomogeneity.
Around the drive shaft in different host products supporting the use, working environment is more complex, such as temperature, humidity, water, steam and dust, sand, oil, acid, alkali, corrosion medium, salt water, radiation, etc., is to choose the coupling must be considered one of the important factors. For high temperature, low temperature, oil, acid, alkali medium work quality, unfavorable choose by the general rubber for the elastic component material of flexible coupling, flexible coupling should choose metal elastic component, such as the diaphragm coupling, snake-like spring coupling, etc.
