Design can directly influence the quality of industrial products with manufacture level.
Gear is main basic transmission element in automobile industry, and the quality of gear directly affects the noise of automobile, put down
Stability and service life.Gearbox gear is the important component of automobile engine, for changing engine crankshaft and power transmission shaft
Speed ratio.Gearbox gear in the course of the work, by the contact passing power of the flank of tooth, two flank of tooth in contact process is engaged,
Existing rolling also has slip, larger compression and frictional force be present.
But two phase gears the flank of tooth in contact process is engaged, particularly in this high-speed overload of gearbox
Gear drive in, because the frictional force between mesh tooth face is larger, relative velocity is big, causes region of engagement temperature high.Typically can be
Lubricating oil is scribbled on gear, makes to form oil film between the flank of tooth, reduces abrasion.But because the friction between mesh tooth face causes temperature mistake
Height, and easily make deterioration of lubricant, it is impossible to gear lubrication, make the abrasion between the flank of tooth more serious.
