齿形链是由一系列的齿链板和导板交替装配且销轴或组合的铰接元件连接组成,相邻节距间为铰连节。根据导向型式可分为:外导式齿形链、内导式齿形链和双内导齿形链。

齿形链又称无声链(SilentChain),属于传动链的一种形式。我国的国家标准为:GB/T10855-2003《齿形链和链轮》。齿形链是一种应用广泛的重要机械基础件,主要用在高速、重载、低噪音、大中心距的工况下,其传动性能优于齿形带传动、齿轮传动以及磙子链传动,以成为众多行业首选对传动形式之一,以啮合形式分可分为内啮合齿形链、外啮合齿形链和内外复合啮合齿形链,其中内外复合啮合齿形链的噪音最小,应用也最广泛。

主要特点:

1、噪音小 齿形链是通过工作链板与链轮齿的渐开线齿形进行啮合传递动力,与滚子链和套筒链相比其多边形效应明显降低,冲击小、运动平稳、啮合噪音较小。

2、可靠性较高 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影响整根链条的工作,使人们能够及时发现并更换,如需增加承载能力只需在宽度方向较小尺寸(增加链片排数)。

3、运动精度高 齿形链各链节磨损伸长均匀,可保持较高的运动精度。

齿形链条主要应用范围:齿形链主要应用在纺织机械和无心磨床,传送带机械设备。
