Synchronous bandwidth selection

点击数:743    发布日期:2018-04-28

The bandwidth of the timing belt is equal to the basic bandwidth of the timing belt multiplied by the value of the design power, the basic rated power and the coefficient.

In other words, if the parameter A is calculated, there is a coefficient B, but when calculating B, it is also necessary to know the value of A. This is a very common situation. The processing method generally assumes a value, such as the value of B, and then calculates the value of A, and then calculates the value of B. Then it is compared with the hypothetical value. If it is not equal, it will be calculated again according to the calculated value B. This will be repeated two or three times. In general, the hypothetical value and the calculated value are basically the same.


The timing belts and the timing belt wheels match each other as long as they match each other, that is, what type of timing belts are to be matched with the same type of timing pulleys. However, the specific timing belt length can be queried by the belt length series of the timing belt. Timing pulleys need to select the number of teeth of the timing pulleys. These realities can be found in the selection manual of the timing pulleys, and then use it to determine the number of teeth in the timing belt.

Belt length calculation

In daily work, we need to select different timing belts and timing pulleys as needed. However, the timing belt length of each mechanical instrument is different, so how do we calculate the length of the timing belt we want to buy so that the timing belt we buy can be accurately used on our mechanical instruments? It takes us to calculate the length required by the formula.

We set the radius of the big wheel to be the radius r2 of the r1 little wheel, and the distance between the centers of the two wheels d, then the total length is the part that is affixed to the big wheel + the part that is attached to the small wheel + the length of the air suspension, that is:


It should be noted that PI is the PI and arccos is the inverse cosine function.
