直齿轮的总效率通常是根据三种类型的功率损失:齿轮啮合、轴承和间隙或者搅拌阻力。一般计算假设外啮合的齿轮效率是E=0.98,内啮合的齿轮效率是E=0.99。但是基于这样的假设,计算功率损失会导致设计中在计算其它系数时的大错误。齿轮的啮合效率可以从下式计算得到
The total efficiency of spur gears is usually based on three types of power loss: gear meshing, bearings and clearances or stirring resistance. The general calculation assumes that the external gear efficiency is E = 0.98 and the internal gear efficiency is E = 0.99. But based on this assumption, calculating power loss can lead to big errors in the design of other coefficients. The gear meshing efficiency can be calculated from the following formula
