Worm and worm gear transmission is composed of crossed helical gear transmission evolved. The small gear indexing on the cylindrical surface of wound for more than a week, the pinion shaped like a screw, known as worm. The big gear called worm. Worm worm gear worm shape according to different can divide: cylindrical worm drive Globoidal Worm Gearing, and conical worm drive of three types. If the worm indexing cylindrical surface of the bus is changed to be a circular arc, so that it is partially encloses the worm, the worm so called globoid worm gear, meshed with the worm gear called globoidal worm and.

Worm gear and worm by crisscross shaft helical gear transmission of evolved. Small gear teeth in dividing the YuanZhuMian around a week or more, such small gear appearance like a screw, called the worm. Big gear called the worm gear. Worm worm gear and worm shape according to the different can be divided into: cylindrical worm transmission, curve worm transmission and cone worm drive three types. If the worm dividing YuanZhuMian bus bar instead of circular arc form, make be worm gear and part of the cover, the worm called curve worm, and engages the worm gear and worm called curve.

齿轮是直接接触物体、操作成双,传递,实现运动和部队形成一个旋转的轴轴到另一个人,或从一个滑板(架),通过对预测先后从事叫作齿。齿侧面。对齿轮的接触表面必须对齐牙齿以这样一种方式是积极的驱动负载传送;也就是说,必须不取决于摩擦接触。如图所示,在治疗身体的直接接触,这要求正常的表面可以通过一种关键性轴驱动或者跟随者。当它被称为直接接触物体、摆线针轮和渐开线齿形提供一个积极的动力和一个统一的速度比;如下。、共轭行动。基本关系。齿轮副中较小的一个叫做齿轮、大一些的齿轮。当齿轮是在驱动轴上的一对充当一个减速机;当齿轮传动是一种速度,这对搭档增氧机配件。齿轮更常用于降低它的速度比增加。如果一个齿轮的牙齿旋转有N在N转每分钟,产品N * N帽子维每分钟“牙齿”。这种产品都必须是相同的交配的成员获得了合作伙伴,如果每一个齿齿轮形成交配当它经过的地区的齿啮合。共轭齿轮为各种类型、齿轮比和速度比都是给定的比率的齿数齿轮的齿数齿轮。如果一个齿轮的牙齿和一交配100插有20起,这个比率是100/20 = 5。因此齿轮旋转速度的五倍,无论作为齿轮的齿的速度。他们的观点被称为场上的接触点,因为它位于线的中心,它是唯一的在哪个点上齿侧面有纯滚动接触。在不平行轴齿轮,non-intersecting也有沥青圈,但其rolling-pitch0fircle概念不在于有效。 主要是由齿轮类型确定处置之轴;
