The ball caged constant angular velocity universal joint with dividing rod is used in the front driving axle of tractors and automobiles. The angular velocity non-homogeneity of the universal joint depends upon the parameters of dividing rod. Presently no literature states how to determine the optimized parameters theoretically. The existing method is to give these parametersa, b. m a series of ratios, such as m/a, m/b, experiments, are made according to these ratios and the experimental results are described in curves. The method mentional above lacks theoretical basis.Now we have sdved the problem with the theory of approximation in this paper. It also deduces the satisfying relations between these parameters.

The deviation of teeth-thickness and the centredistance is referred to as the foundationof compute backlash in mating gears. Thus, we shall be led to consider the motionin circumferential clearance, which is meant arc on the pitch circle between the non-working flanks when the working flanks are in contact, and. to analyse the processin meshes of mating gears. First, let us only consider the deviation of teeth-thickness.In this case, it corresponds to the pure rotation. The planetary gear in this instantlooked as if it fixed on the eccentric and there is not relative motion between them.Therefore computing backlash can be achieved according to common method. Secondly,let us consider computing the backlash only produced by deviation of the centredistance.In this case, first, derive the theoretically formula for compute the backlash incircuferential clearance on external spur gears in mating, and then on planocentric. Inplanocentric, the motion in its circumferential clearance is co responding with the rotationof its driven eccentric shaft and pure translation of planetary gear along with its center.

The plane enveloping worm gearing of hydrostatic lubrication is a new type of worm gearing. It can be applied both to the graduated mechanism of heavy gear machine tool and to power drive in Some situations. Applying relative theory of gear engagement and hydrostatic technique, this paper expounded the engagement conditions that is required to realize hy- drostatic lubrication of the plane enveloping worm gearing, and suggested two methods of determing parameters of the place of pocket according to these conditions, that is the nomogram methed and the methed of shape and place of second kind side curves. Begin with analy sing guide normal curvature in normal direction of contact line of tooth flank as well as its variation, the tooth flank near the contact line on worm was proximately processed to sim- ply research to properties of hydrostatic film. On the basis of the above, this paper through determing seal side place of film introduced conception of efec- tive loading area, and researched pressure distribution and loading capability as well as rigidity of hydrostatic film. Take the fixed restriction as an exam- ple, some main equations for performing design and study of hydrostatic lu- brication have been given. Lastly, the subject of drive continuity under hy- drostatic lubrication was discussed and verified. In the paper, author calculated same practical examples and enumerated partial results.

液体静压润滑平面包络蜗轮传动是一种新型的蜗轮传动。它既可用在大型齿轮加工机床中作为分度机构,又可用于其它场合作动力传递用。本文运用齿轮啮合原理和液体静压技术的有关理论,阐述了为使平面包络蜗轮副实现静压润滑其啮合性能所必须满足的要求,提出了根据这些要求来确定油室位置参数的两种方法:“线图法”和“二界曲线形位法”。为了简化对齿面间静压油层性质的讨论,文章还从分析齿面间沿接触线法线方向的诱导法曲率及其变化入手,对接触线附近的蜗杆齿面作了近似处理。在此基础上,通过对封油面边界位置的确定,引入了有效承载区的概念;研究了静压油层的压力分布、承载能力及刚度等性能参数;并以固定节流形式为例,给出了进行静压润滑的设计和研究的几个主要公式。最后还对静压润滑状态下传动的连续性问题作了讨论和验证。文中,还结合具体实例进行了计算,并列举了部分计算结果。其方法可供设计或进一步研究时参考。
