19、.1 Abstract: The important position of the wheel gear can't falter in traditional machine and modern machines.The wheel gear mainly install the direction that delivers the dint at the principal axis box. The passing to process to make them can is divided into many model numbers, used for many si
20、tuations respectively.8.2 Key words: Wheel gearIn the force analysis of spur gears, the forces are assumed to act in a single plane. We shall study gears in which the forces have three dimensions. The reason for this, in the case of helical gears, is that the teeth are not parallel to the axis of ro
21、tation. And in the case of bevel gears, the rotational axes are not parallel to each other. There are also other reasons, as we shall learn.Helical gears are used to transmit motion between parallel shafts. The helix angle is the same on each gear, but one gear must have a right-hand helix and the o
22、ther a left-hand helix. The shape of the tooth is an involutes helicoids. If a piece of paper cut in the shape of a parallelogram is wrapped around a cylinder, the angular edge of the paper becomes a helix. If we unwind this paper, each point on the angular edge generates an involutes curve. The sur
23、face obtained when every point on the edge generates an involutes is called an involutes helicoids.The initial contact of spur-gear teeth is a line extending all the way across the face of the tooth. The initial contact of helical gear teeth is a point, which changes into a line as the teeth come in
24、to more engagement. In spur gears the line of contact is parallel to the axis of the rotation; in helical gears, the line is diagonal across the face of the tooth. It is this gradual of the teeth and the smooth transfer of load from one tooth to another, which give helical gears the ability to trans
25、mit heavy loads at high speeds. Helical gears subject the shaft bearings to both radial and thrust loads. When the thrust loads become high or are objectionable for other reasons, it may be desirable to use double helical gears. A double helical gear (herringbone) is equivalent to two helical gears
26、of opposite hand, mounted side by side on the same shaft. They develop opposite thrust reactions and thus cancel out the thrust load. When two or more single helical gears are mounted on the same shaft, the hand of the gears should be selected so as to produce the minimum thrust load.Crossed-helical
27、, or spiral, gears are those in which the shaft centerlines are neither parallel nor intersecting. The teeth of crossed-helical fears have point contact with each other, which changes to line contact as the gears wear in. For this reason they will carry out very small loads and are mainly for instru
28、mental applications, and are definitely not recommended for use in the transmission of power. There is on difference between a crossed helical gear and a helical gear until they are mounted in mesh with each other. They are manufactured in the same way. A pair of meshed crossed helical gears usually
29、 have the same hand; that is, a right-hand driver goes with a right-hand driven. In the design of crossed-helical gears, the minimum sliding velocity is obtained when the helix angle are equal. However, when the helix angle is not equal, the gear with the larger helix angle should be used as the dri
30、ver if both gears have the same hand.Worm gears are similar to crossed helical gears. The pinion or worm has a small number of teeth, usually one to four, and since they completely wrap around the pitch cylinder they are called threads. Its mating gear is called a worm gear, which is not a true heli
31、cal gear. A worm and worm gear are used to provide a high angular-velocity reduction between nonintersecting shafts which are usually at right angle. The worm gear is not a helical gear because its face is made concave to fit the curvature of the worm in order to provide line contact instead of poin
32、t contact. However, a disadvantage of worm gearing is the high sliding velocities across the teeth, the same as with crossed helical gears.Worm gearing are either single or double enveloping. A single-enveloping gearing is one in which the gear wraps around or partially encloses the worm. A gearing
33、in which each element partially encloses the other is, of course, a double-enveloping worm gearing. The important difference between the two is that area contact exists between the teeth of double-enveloping gears while only line contact between those of single-enveloping gears. The worm and worm ge
34、ar of a set have the same hand of helix as for crossed helical gears, but the helix angles are usually quite different. The helix angle on the worm is generally quite large, and that on the gear very small. Because of this, it is usual to specify the lead angle on the worm, which is the complement o
35、f the worm helix angle, and the helix angle on the gear; the two angles are equal for a 90-deg. Shaft angle.中文譯文:1 什么是減速器 減速器是一種動(dòng)力傳達(dá)機(jī)構(gòu),利用齒輪的速度轉(zhuǎn)換器,將馬達(dá)的回轉(zhuǎn)數(shù)減速到所要的回轉(zhuǎn)數(shù),并得到較大轉(zhuǎn)矩的機(jī)構(gòu)。 1.1 減速器的作用 1.1.1降速同時(shí)提高輸出扭矩,扭矩輸出比例按電機(jī)輸出乘減速比,但要注意不能超出減速器額定扭矩。 1.1.2 減速同時(shí)降低了負(fù)載的慣量,慣量的減少為減速比的平方。大家可以看一下一般電機(jī)都有一個(gè)慣量數(shù)值。 1.2 減速器的種類 一
