用碳钢或合金钢制造的齿轮,其齿面硬度可分为软齿面,中硬齿面和硬齿面三种。我厂产品所用的齿轮决大部分为硬齿面齿轮。硬齿面齿轮在热处理过程中不可避免的要产生热处理变形,由于变形造成齿轮副运转噪音大,传动效率低,使用寿命短。为消除热处理变形,提高齿轮精度,一般采用珩齿或磨齿的方法进行热处理后精加工,珩齿工艺的加工效率较高,齿面质量也较好,但它对热处理变形的纠正能力差,因此难以有效地提高齿轮精度。齿轮选用磨削工艺生产效率低,加工成本高,磨削后轮齿表面产
Gear made of carbon steel or alloy steel, the tooth surface hardness can be divided into soft tooth surface, in the hardened and hardened three. Most of the gears used in our products are hardened gears. Hardened gear in the heat treatment process inevitably have to heat deformation, gear deformation caused by noise, transmission efficiency, short service life. In order to eliminate the deformation of heat treatment and improve the gear accuracy, the general use of honing or grinding method of heat treatment after finishing, honing process of higher processing efficiency, tooth surface quality is better, but its ability to correct heat treatment deformation is poor, So it is difficult to effectively improve the gear accuracy. Gear grinding process used in the production of low efficiency, high processing costs, after grinding the gear surface production
