[摘要] 齿轮减速器是各种机器中广泛采用的重要部件，其主要功用是减速增力（降低转速，增大扭矩）。为使机器具有良好的性能，齿轮减速器正向着大减速比、高效率、小体积的方向发展。
目前的少齿差行星传动装置仍存在如下问题：
（1）转臂轴承承受很大的动载荷，寿命较短；
（2）由于其上的一对行星齿轮仅实现了静平衡而未能实现动平衡，因而当输入轴高速转动时，其支撑轴承上将有较大的周期性变化的惯性力偶作用，导致产生振动；
（3）因行星齿轮只有两个，且为避免出现过大的振动，行星齿轮一般设计得较薄，因而其功率分流的效果仍然较差，承载能力受到了限制（目前国内产品最大传递功率为45kw，国外最大为100kw）;
(4)尽管孔销式输出机构为目前公认的最好机构，但在冲击力较大的场合常出现销套被挤破的现象。
现在提出的动平衡少齿差行星减速器是一种完全平衡的行星减速器，并具有合理的输出系统，可以克服现有少齿差行星减速器的上述缺点。

DSL-60-50 transient equilibrium with small tooth difference reduction gear design
[ABSTRACT]: The speed reducer gear is the important part which in each kind of machine widely uses, its main function is decelerates increases the strength (despinning, increases torque). In order to enable the machine to have the good performance, the speed reducer gear to is being big let down, the high efficiency, the small volume direction develops.
The present with small tooth difference planetary transmission device still had the following problem:
(1) rotary arm of force bearing withstanding very big moves the load, the life is shorter;
(2) because an above pair of planet gear only realized static equilibrium but has not been able to realize the transient equilibrium, thus worked as when input axis high speed rotation, on its strut bearing will have the bigger periodic variation inertial couple the function, caused to have the vibration;
(3) because the planet gear only has two, also for avoids appearing the oversized vibration, the planet gear general layout thinly, thus its power divergence effect was still worse, the bearing capacity has been restricted (at present domestic product biggest transmission power was 45kw, overseas most greatly was 100kw);
(4) Tubal hole sells the type output element the best organization which recognizes as at present, but often appears in an impulse bigger situation sells the set the phenomenon which crushes.
Now proposed the transient equilibrium with small tooth difference planet reduction gear is one kind of completely balanced planet reduction gear, and has the reasonable output system, may overcome the existing with small tooth difference planet reduction gear the above shortcoming.
[Key words]: reduction gear rotary arm of force bearing with small tooth difference the planet gear
