PU同步带的张紧方式

其实不管是是什么样的同步带,对于大多数PU同步带生产厂家来说,张紧力都是比较重要的。在这两种张紧方法中,所使用的张紧轮类型和大小,以及惰轮放置的位置,是不一样的。
In fact, no matter what kind of synchronous belt it is, the tension is more important for most Pu synchronous belt manufacturers. In the two tensioning methods, the type and size of the tensioning wheel used and the position of the idler are different.
PU同步带是综合了带传动,链条传动和齿轮传动的优点而设计出的产品。根据同步带的摩擦传动原理,同步带必须在张紧后才能正常工作。运转一定之间带会松弛,为了保证同步带的能力,必须重新张紧,才能正常工作。
Pu synchronous belt is a product designed by combining the advantages of belt drive, chain drive and gear drive. According to the friction transmission principle of synchronous belt, the synchronous belt must be tensioned before it can work normally. In order to ensure the capacity of the synchronous belt, it must be re tensioned before it can work normally.
PU同步带传动具有带传动、链传动和齿轮传动的优点。同步带传动由于带与带轮是靠啮合传递运动和动力,故带与带轮之间无相对滑动,能保证准确的传动比。同步带通常以钢丝绳或玻璃纤维绳为抗拉体,氯丁橡胶或聚氨酯为基体,这种带薄而且轻,故可用于较高速度。

Pu synchronous belt drive has the advantages of belt drive, chain drive and gear drive. Synchronous belt drive because the belt and pulley transmit motion and power by meshing, there is no relative sliding between the belt and pulley, which can ensure accurate transmission ratio. The synchronous belt usually takes steel wire rope or glass fiber rope as the tensile body and neoprene or polyurethane as the matrix. This kind of belt is thin and light, so it can be used for higher speed.
但是大家要知道的是PU同步带的张紧基本上都是一样的,分为内侧张紧和外侧张紧。一般来说,内侧张紧,优先使用同步轮,而不使用光滑轮,因为使用光滑轮,噪声和磨损都会增加。同时要求张紧同步轮的直径,不得小于小轮直径。
But you should know that the tension of Pu synchronous belt is basically the same, which is divided into inner tension and outer tension. Generally speaking, for internal tensioning, it is preferred to use synchronous pulley instead of smooth pulley, because the use of smooth pulley will increase noise and wear. At the same time, the diameter of the tensioning synchronous wheel shall not be less than the diameter of the small wheel.
但是对于一些供应商来说,内侧张紧也可以使用不带齿的平惰轮,但是前提是,直径必须大于等于40倍传动带齿距。另外,内侧张紧会减小包角,也就减小了有效啮合齿数,所以为了不过多地减小包角,内侧张紧轮应当尽量靠近大轮附近。而宁波同步带外侧张紧,张紧轮因为是和传动带背面接触,所以不需要带齿,光滑的滚轮即可。但是,无论是内侧张紧,还是外侧张紧,都需要把张紧轮放置在松边,这样在启动的时候,才不于松边和紧边柔度差距太大,也就减小了跳齿的可能性。
However, for some suppliers, flat idlers without teeth can also be used for inner tensioning, provided that the diameter must be greater than or equal to 40 times the drive belt pitch. In addition, the inner tensioning will reduce the wrap angle, which will reduce the number of effective meshing teeth. Therefore, in order to reduce the wrap angle as much as possible, the inner tensioning wheel should be as close to the big wheel as possible. The outer side of Ningbo synchronous belt is tensioned. Because the tensioning wheel is in contact with the back of the transmission belt, there is no need for belt teeth and smooth rollers. However, whether it is inner tensioning or outer tensioning, the tensioning wheel needs to be placed on the loose edge, so that when starting, the flexibility gap between the loose edge and the tight edge will not be too large, which will reduce the possibility of tooth skipping.
