    升降机齿条加工要点须记住

    来源:http://www.jnzkjx.cn/ 日期:2020-07-28 发布人:kaizejixie
    齿轮加工通常都使用滚齿机和插齿机来工作,对于调整维护方便,对于大规模的生产来说生产效率就会偏低。后来对于滚刀、插刀刃磨后的再次涂镀技术的产生,可以使得刀具能够明显地提高使用时间,能够减少了换刀次数和刃磨时间,提率。在剔齿过程中,径向剃齿技术有很大的优势,包括效率高,设计齿形、齿向的修形容易实现。
    Gear processing usually uses hobbing machine and gear shaper to work, which is convenient for adjustment and maintenance, and the production efficiency will be low for large-scale production. Later, for hobs, inserts after grinding again coating technology, can make the tool can significantly improve the use time, can reduce the number of tool change and grinding time, improve efficiency. In the process of gear picking, radial shaving technology has great advantages, including high efficiency, and the modification of tooth profile and tooth direction is easy to realize.
    在热处理过程中齿轮要求使用渗碳淬火,这样才能保证其良好的力学性能。对于热后不再进行磨齿加工的产品,稳定可靠的热处理设备也是必须具备的。磨削加工过程中,主要是对经过热处理的齿轮内孔、端面、轴的外径等部分进行精加工,以提高尺寸精度和减小形位公差。
    In the process of heat treatment, the gear should be carburized and quenched so as to ensure its good mechanical properties. Stable and reliable heat treatment equipment is also necessary for the products that are no longer grinded after heat treatment. In the grinding process, the inner hole, end face and outer diameter of the shaft after heat treatment are mainly processed to improve the dimensional accuracy and reduce the geometric
    tolerance.

    齿轮加工主要是控制齿轮在运转时齿轮之间传递的精度,比如传动的平稳性、瞬时速度的波动性、若有交变的反向运行,其齿侧隙是否达到要求范围,如果有冲击载荷,应该稍微提高精度,从而减少冲击载荷带给齿轮的破坏。
    Gear processing is mainly to control the transmission accuracy between gears during gear operation, such as transmission stability, instantaneous speed fluctuation, if there is alternating reverse operation, whether the backlash reaches the required range, if there is impact load, the accuracy should be slightly improved, so as to reduce the damage of impact load to the gear.
    如果以上这些设计要求比较高,则齿轮精度也就要定得稍高一点,反之可以定得低一点。但是,齿轮精度定得过高,会上升加工成本,需要综合平衡。(齿厚)偏差等级也是设计者综合具体工况给出的等级,精密传动给高一点,一般机械给低一点,闭式传动给高一点,开式传动给低一点。
    If the above design requirements are relatively high, the gear accuracy should be set a little higher, and vice versa. However, if the gear accuracy is set too high, it will increase the processing cost and need comprehensive balance. (tooth thickness) deviation grade is also the grade given by the designer according to the specific working conditions. The precision transmission is higher, the general machinery is lower, the closed transmission is higher, and the open transmission is lower.
