目前,一般工业用的齿轮制造精度较低,工作时,齿面接触不良,使用寿命短。此外,由于装配精度和工作时齿轮等变形的影响,即使加工精度比较高的齿轮,在满载工作时,齿面的接触情况也会产生变化。因此,要求齿轮在满载下工作时,达到全齿均匀接触,使工作载荷在齿面上均匀分布,一直是国内外齿轮行业所难以解决的问题。 At present, the general industrial gear manufacturing accuracy is low, work, poor contact with the tooth surface, short service life. In addition, due to the assembly accuracy and deformation of gears and other work-time effects, the contact condition of the tooth flanks will change even when the work load is high even though the gears with high machining accuracy are used. Therefore, when the gear is required to work under full load, it reaches the uniform contact of the whole tooth, and the work load is evenly distributed on the tooth surface, which has always been a difficult problem to be solved by the gear industry at home and abroad.
