The utility model relates to a pressure synchronous belt transmission device with small tooth difference, which belongs to the field of transmission machinery. It is composed of input shaft, input shaft bearing, synchronous pulley, synchronous belt, positioning ring, positioning shaw, wheel cover, output shaft, body, etc. The feature is that the synchronous pulley is supported on the eccentric bearing of the input shaft, the synchronous belt is bonded with the positioning ring and fixed on the body. The number of teeth of the pulley is less than one to several teeth of the synchronous belt. It is located in the synchronous belt and intermeshes with each other, thus driving the synchronous pulley to roll along the inner circumference of the synchronous belt. The output shaft rotates through the output mechanism. It is simple and reliable, compact, light, balanced and silent. Its transmission efficiency is over 95%. Its cost is less than that of the existing ones. Cycloid needle wheel and worm drive are reduced by 1/3 to 1/2. The synchronous belt does not need lubrication. It is easy to replace and has longer service life. It is widely used in mechanical transmission collar with large deceleration ratio (including precision without backlash). Domain.

加壓同步帶少齒差傳動裝置
:本專利屬于傳動機械領域,具體涉及一種同步帶與齒數比同步帶少1至數齒的同步帶輪。構成的一種新型的同步帶少齒差行星傳動。
技術介紹
:帶傳動歷史悠久,帶傳動具有振動小、運轉平穩無聲,很大的中心距也能實施傳動。減振、不需潤滑、傳動帶容易更換、制造簡易等一系列特點,迄今仍是一種重要、應用比較廣泛的傳動方式。這種傳動中同步帶傳動,除上述特點外,還具有帶長度不變,傳動比恒定,結構更緊湊。效率高的性能,但制造安裝中心距等要求較高,所能達到傳動比有限,一般i<10,不能適應需要更大傳動比的要求。
技術實現思路
:本專利技術的目的是:以普通標準的同步帶與比帶少1齒至數齒的同步帶輪,組成特定的加壓同步帶少齒差傳動裝置。使其既保持同步帶傳動平穩、無聲、高效的特點,又能實現很大傳動比、結構更簡單、緊湊,應用范圍更廣。本專利技術解決其技術問題的具體方案是:(圖1)(圖2)(圖3),普通同步帶(2)彎曲呈圓環形。同步帶外周圓柱表面與定位圓環(3)粘接固定,裝在機體(10)中部。定位圓環(3)底部以定位肖(14)與機座(11)連接固定。機體(10)一側,裝有輸入軸軸承(13)及其支承的輸入軸(6)。平衡配重(15)。輸入軸(6)一端偏心輪(偏心距為e)外圍,裝有軸承(5)及同步帶輪(1)。同步帶輪齒數比同步帶(2)齒數少1齒或數齒。兩者模數、周節相同,彼此嚙合,但嚙合直徑尺寸公差,有一定少量過盈配合量δ(圖3),裝配時通過輪蓋(4),螺栓壓緊,使內部同步帶輪對同步帶在嚙合區加壓。相應形成1齒或數齒差具有微量彈性變形的、少齒差內嚙合齒輪付。機體(10)的另一側裝有 ...
