Analysis of the tooth trimming amount of the pinion


For high-speed herringbone gears, the normal gear tooth shape and tooth direction are not trimmed, and the pinion tooth tip trimming is conducive to the smoothness of the motion. Both ends of the herringbone gear teeth should be trimmed with necessary teeth, and the trimming amount can be Determined by deformation calculation.
The tooth direction trimming amount on the pinion torque side should be larger than the non-torque side, and the tooth direction trimming can eliminate the eccentric load and improve the contact accuracy. The machining process of the pinion is relatively simple, and will not be described here, as long as special attention is paid to the accuracy of the grinding and the accuracy of the dynamic balance.
Since the large gear is a welded gear, the glass screen printing machine is important for high-speed gears to ensure the machining accuracy and deformation.
The processing technology of the welding gear is more complicated. The specific processing technology is as follows: the ring gear (35CrMo) and the wheel hub (35#) are forged by vacuum degassing and refined steel, and the ultrasonic inspection is performed after roughing the vehicle (defective equivalent Before the installation, the roll engagement test should be done. The ferrous sulfate heptahydrate is used for the roll meshing on a dedicated counter-rolling frame, mainly checking the contact area of ​​the gear pair.
