Simple understanding of the classification of the synchronous belt
Simple understanding of the classification of the synchronous belt
同步帶在我們生活中已經比較容易的見到，而對于它的一些簡單分類很多非業(yè)內人士也不太清楚，下面就給大家簡單的介紹一下同步帶的分類。
Synchronous belt to see in our life is relatively easy, and for some simple classification and many of its non industry also not too clear, here we give a simple classification of the synchronous belt.
同步帶因牙齒則可以分為梯形齒和弧齒兩類，而其中的弧齒又有三種系列，也就是H系列又稱HTD帶，即是圓弧齒，S系列又稱為STPD帶，即是平頂圓弧齒，和R系列，也就是凹頂拋物線齒。
Synchronous belt with teeth can be divided into two kinds of trapezoid and arc tooth, and arc gear which has three series, the H series is also called HTD, is a circular arc tooth, S series is also known as the STPD band, is flat circular arc tooth, and R series, is a concave parabola tooth.
則梯形齒同步帶有分為單面有齒和雙面有齒兩種，簡單的稱為單面帶和雙面帶。而雙面帶又按齒的排列方式分為對稱齒型（代號DA）和交錯齒型（代號DB）。對于梯形齒同步帶則是有節(jié)距制和模數(shù)制兩種。在我國則是采用的是節(jié)距制。并根據ISO 5296制訂了同步帶傳動相應標準GB/T 11361～11362-1989和GB/T 11616-1989。對于弧齒同步帶，它出了齒型是曲線型外，其它的結構都和梯形齒同步帶大致相同，帶的節(jié)距相當，齒形也比較高，齒根較厚和齒根圓角半徑等都比梯形齒大。當帶齒受載后，分布的應力狀態(tài)也比較好，能夠平緩齒根的集中受力，從而提高了齒的承載能力。所以，弧齒同步帶比梯形齒同步帶傳遞的功率大，并且還能防止嚙合過程中齒的干涉。同時由于弧齒同步帶的耐磨性能比較好，工作時噪音也比較小，且不用潤滑，所以常用于有粉塵的惡劣環(huán)境?，F(xiàn)在已經廣泛的用在食品、汽車、紡織、制藥、印刷、造紙等行業(yè)。
The trapezoidal toothed synchronous with divided into single-sided and double-sided toothed gear two, simply called single and double-sided tape. The double-sided tape and according to the tooth arrangement is divided into symmetrical tooth type (code DA) and staggered tooth type (code DB). For trapezoidal toothed synchronous belt is the pitch system and modular system two. In our country it is using the pitch system. And according to ISO 5296 made synchronous belt transmission, the corresponding standard GB/T 11361 ~ 11362-1989 and GB/T 11616-1989. For the arc tooth synchronous belt, it is out of a tooth is curved, other structures and trapezoidal toothed synchronous belt roughly the same, with pitch, tooth shape is relatively high, the root thickness and fillet radius than the trapezoidal teeth. When the belt teeth under load, distribution of stress state is also good, to smooth the root concentrated force, so as to improve the bearing capacity of the teeth. So, arc tooth synchronous belt power ratio of trapezoidal toothed synchronous belt transmission, and can prevent the interference of tooth in meshing process. At the same time as the wear resistance of arc tooth synchronous belt is better, when the noise is relatively small, and no lubrication, so commonly used in dust environment. It has been widely used in the food, pharmaceutical, automotive, textile, printing, paper and other industries
