新齿标“JB 179-81”规定:齿形误差在齿顶或齿根处偏向齿体内,国产锥面砂轮磨齿机,只能磨标准渐开线。其理论齿形误差为直线,在齿顶或齿根的实际误差偏内或偏外,各占一半。故按新标准检验时,磨齿不合格率可能占一半,而成为生产的关键。对一般齿轮,迫切需要找到一种稳定磨出2～3微米凸形齿的措施。生产实践也证明,采用修缘齿形、挖根齿形、凸齿形,可以提高传动质量,减少振动和噪声,但也迫切需要解决修缘齿形的磨齿。
The new gear “JB 179-81” provides: tooth-shaped tooth or tooth root at the tooth root bias bias body, the domestic conical grinding wheel grinding machine, can only wear standard involute. The theoretical tooth profile error is a straight line, half of the actual error in the addendum or tooth root, or half of each. Therefore, according to the new standard test, the failure rate of grinding teeth may account for half, and become the key to production. For a general gear, there is an urgent need to find a way to stabilize the convex teeth of 2 to 3 microns. Production practice also proves that the use of repair tooth profile, digging root profile, convex profile, can improve the transmission quality, reduce vibration and noise, but also an urgent need to solve the edge grinding tooth.
