作者曾提出新的环面蜗杆传动,即在滚齿机上用球面砂轮磨削环面蜗杆时增加一个螺旋运动,使母面成为圆弧螺旋面,并以平面二包磨头的基础作了大圆弧半径的接触线分析,制造了二包蜗轮副用于拉丝机的主传动上,通过研究用环面砂轮磨削面蜗杆,同样可得到这种传动;并解决了一包传动的母面蜗轮的通用滚刀齿形问题-圆弧螺旋面蜗杆,在本文中除讨论该传动副的接触线,诱导曲率和润滑角外,将研究用滚刀的加工方法、滚刀齿形成形原理及环面蜗杆的双面磨削法。 相似文献

The synthesis of cylindrical worm gears is considered, in the case where the generating worm consists of standard worm cutters for cylindrical gears. Standardization of the dimensions of the initial and generating worms simplifies the manufacture of worm pairs and increases production efficiency by reducing the range of gear-cutting tools. 相似文献

Worm reducers with a double enveloping toroidal surface are a new type of reducer with higher wear resistance and longer service life. A series of contact fatigue tests of worm pairs has been carried out on a microcomputer-controlled test stand of closed power flow type, using an incremental method of increasing the load. During the test, the worm tooth flank completed 2.2 × 107 cycles, and the worm gear tooth flank 1.1 × 106 cycles. Meanwhile, the state of the flank was duplicated by means of a chemical film. This paper discusses the whole process of the occurrence and development of surface cracks as well as the formation of fatigue peeling. It should provide a reliable basis for definition of the law of fatigue damage of the worm gear tooth flank. 相似文献

A worm and worm wheel gearing is widely used in a geared motor unit for the convenience and safety of an automobile. For mass
production of a high quality worm, the current rolling process is substituted with the milling process. The milling process
offers comparatively accurate machining quality and high production capacity for worm manufacturing. Moreover, since the milling
process enables the integration of all operations of worm manufacturing on a CNC lathe, production efficiency can be remarkably
improved. However, there are several important factors to be considered for producing high quality worms such as cutting force,
tool-workpiece interference, and others. Planetary milling and side milling are generally applied to machine worms. In this
study, the cutting characteristics of worm machining on an automatic lathe are investigated for two types of milling processes
and those processes are compared with each other. A tool-tip trajectory model based on tool-workpiece interaction is proposed,
and then tool-workpiece interference and cutting force are simulated with the model. The simulation results are verified through
numerous experiments. The experimental results show the cutting characteristics of each milling process and the efficiency
for mass production of a high quality worm.
