随着高速链传动技术的不断发展,新型汽车,摩托车发动机越来越广泛的应用了齿形链条,高速时,采用齿形链比采用滚子链条和齿形带具有明显的优点,但是由于存在“多变效应”减少瞬间啮合冲击和减轻传动过程中“多边效应”减少瞬间啮合冲击和减轻磨损,降低噪音的新型齿形链条。变节距齿形链条也称HV无声齿形链条,其铰链机构采用的是滚销式齿形通常有链板和滚销两个主要元件组成,他们和渐开线链轮一起,组成了链传动装置。从HV齿形链的动态工作过程出发。论证了HV齿形链条变节距原理。啮合特性,研究了HV齿形链轮分度圆的确定以及链轮的齿形与加工,以期为变节距齿形链传动的理论研究和生产应用提供参考。
变节距齿形链轮的特点
1,链轮齿侧工作齿形采用渐开线。
2, HV链轮是负变位量很大的变位齿轮
3,和渐开线齿轮相同,HV链轮存在基准齿形。即其参数仅与名义节距P有关。和齿数无关。
4, HV链轮是切顶式。
5, HV链轮的工作齿面是淬硬齿面。
1, HV齿形链传动区别于标准齿形链传动。有三个主要元件:链板滚销渐开线链轮。
2, HV齿形链条与链轮的啮合过程类似齿轮和齿条的啮合过程。啮入啮出过程平稳。
3,由于HV齿形链条的变节距作用,在与链轮啮合过程中,链条横向变动可减少到最低成
4,链轮的分度圆直径取决于名义节距,滚销结构参数和链轮齿数。他是链条传动计算的基
5, HV链轮是负变位量很大的渐开线齿轮。其变位量大小取决与链轮和链轮的定位尺寸。
6, HV链轮基准齿形仅与名义节距有关。而与齿数无关
无声链条的主要特点:
(1)噪声小齿形链(常称为“无声链”)是通过工作链板与链轮齿的渐开线齿形啮合进行传动,因此与滚子链和套筒链相比,啮合噪声较小。
(2)可靠性较高 这是因为齿形链的链节是多片式结构,当其中个别链片在工作中遭到破坏时,并不立即使整根链条断开,从而能使人们及时发现并更换。同时,与相同节距的套筒链和滚子链相比,齿形链传动更紧凑,如需增加承载能力,齿形链传动只需在宽度方向上增加较小的尺寸,而套筒链和滚子链传动则需增加链条的节距或采用多排链
(3)运动精度较高 这是因为在直板滚子链中,由于铰链的磨损,使其内节和外节的实际节距逐渐不同,外节节距变得越来越大,从而降低了运动精度。而齿形链各链节的磨损伸长则相对均匀,因此保持有较高的运动精度。
根据导向分:内导的齿形链条和外导的齿形链条,内外复合的齿形链条 配套齿轮
无声齿形链条的分类:
1,无声齿形链条
2,哈瓦无声齿形链条
3,单轴无声齿形链条圆柱和扁轴
4,无声齿形链条内接触和外接触内导向或者外导向
5,无声齿形链条有的带异形片
6,无声齿形链条有直背的和弧形背的
flat key slot high-speed silent chain tooth-shaped chain matching all kinds of tooth number high-speed gear
Silent conveying chains provide a smooth,durable,flat conveying surface that operates with less vibration and velocity variation than other conveying products.Chains are manufactured from hardened steel components,making them long lasting and tolerant of elevated temperatures.They are available in a variety of standard widths and constructions or can be easily buit to suit a specific application. Linked and pin with a special treatment ,So it has highly wearable and strength to pull and can provide more stable use effects and long usage life,all of the of these products as your demand.
The width of silent chain can from 50mm to 500mm.
Two pin silent chain can provide better use effects and longer usage life than single pin.And with protection plate can offer more safety protection for the product.The chain gear tooth chain Xiangjie: also called silent chain, the chain is a special heat treatment process, and solves the problem that the domestic heat
You can pack the factory.
Do not pass the processing problem, chain plate adopts special steel chain forging and heat treatment, the thickness of 0.2mm, hard, soft, this
The treatment process, to solve the high hardness, hardness of small fragments. Processing, do not wear problems, the use of Zhou Qishou
Life greatly extended (under normal use 3-5 years) according to the central distance of two kinds: 12.7mm, 25.4mm.
Application: the tooth chain has generally matched with the ranks of machine, bottle conveying machine manufacturers.
Detection of the tooth chain: tooth chain we produce have been running for 24 hours in the bottle conveying machine, to be qualified, only
Toothed chain is an important mechanical basis for a wide range of applications, mainly used in high speed, heavy load, low noise, large center distance conditions, the transmission performance is better than that of tooth belt, gear and roller drive, to become a large number of industries preferred form of transmission, can be divided into internal meshing gear the chain meshing form, outer meshing silent chain and the inner and outer meshing silent chain, the inside and outside the compound meshing noise minimum, is the most widely used.
Silent chain (gear chain drive) is an efficient, stable, drive economy. Its transmission speed and capacity are more than the chain belt and other types of silent chain. (toothed chain transmission) of low noise, small vibration, high transmission efficiency of more than 99%. The standard of silent chain chain and sprocket variety, so silent chain drive collocation is flexible, which can meet the different needs of different conditions
The chain shape of silent chain, in order to reduce the stress concentration degree, prolong the fatigue life, enhance the tensile strength of the chain. Stamping technology innovation bring pressure area each link can increase the bearing area. That links at reduced pressure, greatly reduce the chain in the process of using all stretched rate. The link is through shot blasting treatment to increase the fatigue strength, and surface consistent effect.
Silent chain and sprocket is designed to conform to the ASME standard profile using.RP series SC series with the transmission ability of silent chain two times, it can transmit more than 35 meters per second speed and more than 1800kW. When you need to load in the narrow space of high-speed transmission of high load when RP series of silent chain the transmission system is often the transmission type often used.
