Embodiment Construction
[0068] The present invention will be further described below in conjunction with accompanying drawings and examples of implementation.
[0069] The design method of circular-elliptical-noncircular three-wheel synchronous belt transmission, the specific steps are as follows:
[0070] Step 1, such as figure 1 , given the circular active synchronous pulley pitch curve radius r 1 =30mm, circular active synchronous pulley pitch curve cutting diameter p 1 = r 1 , the tensioned synchronous pulley is a non-circular pulley fitted according to the variation of the slack in the circumference of the synchronous belt; the center distance of the three pulleys is L 1 = L 2 = L 3 =100mm, the three wheels are closed convex curves with equal perimeter, calculate the perimeter s=188.4956mm of the pitch curve of the circular active synchronous pulley according to the following formula:
[0071] s=2π×r 1 (1)
[0072] Step 2. Given the eccentricity e of the pitch curve of the elliptical dr...
