皮帶輪傳動的優點有:皮帶輪傳動能緩和載荷沖擊;皮帶輪傳動運行平穩、低噪音、低振動;皮帶輪傳動的結構簡單，調整方便;皮帶輪傳動對于皮帶輪的制造和安裝精度不像嚙合傳動嚴格;皮帶輪傳動具有過載保護的功能;皮帶輪傳動的兩軸中心距調節范圍較大。皮帶傳動的缺點有:皮帶輪傳動有彈性滑動和打滑，傳動效率較低和不能保持準確的傳動比;皮帶輪傳動傳遞同樣大的圓周力時，輪廓尺寸和軸上壓力比嚙合傳動大;皮帶輪傳動皮帶的壽命較短。各類機械設備的皮帶輪的直徑等尺寸都是自己皮帶輪皮帶輪根據減速比配的，根據工作轉速與電機的轉速自己設計。 工作轉速/電機轉速=主動輪直徑/從動輪直徑*0.98(滑動系數)，如使用鋼為材料的皮帶輪,要求線速度不高于40m/s,如使用鑄鐵的材料,要求線速度不高于35m/s，電機轉速與皮帶輪直徑換算比，速度比=輸出轉速:輸入轉速=負載皮帶輪節圓直徑:電機皮帶輪節圓直徑。節圓直徑和基準直徑是一樣的，直徑-2h=節圓直徑，h是基準線上槽深，不同型號的V帶h是不一樣的，Y Z A B C D E，基準線上槽深分別為h=1.6 2 2.75 3.5 4.8 8.1 9.6。皮帶輪節圓直徑就是皮帶輪節線位置理論直徑,有點像齒輪的分度圓直徑.一般用PD表示,外圓一般用OD表示.不同的槽型節圓與外圓的換算公式不一樣,一般我們比較容易測量到皮帶輪的外圓,在根據公式計算出節圓.SPZ:OD=PD+4;SPA:OD=PD+5.5;SPB:OD=PD+7;SPC:OD=PD+9.6。A或SPA的帶輪最小外徑尺寸為80mm，如小于該尺寸，特別是在高速的情況下，皮帶容易出現分層及底部出現裂紋等毛病。SPZ帶，小輪不小于63mm即可。同時要注意皮帶安裝的手法及張力，過小易打滑，過大易損壞皮帶與軸承。
The advantages of the belt pulley drive are: the belt pulley transmits kinetic energy to ease the impact of load; the belt pulley drive runs smoothly, with low noise and low vibration; the structure of the belt pulley drive is simple and easy to adjust; the manufacturing and installation accuracy of the belt pulley drive is not as strict as the meshing drive; the belt pulley drive has the function of overload protection; the adjustment range of the two axis center distance of the belt pulley drive is large. The disadvantages of belt drive are as follows: the belt pulley drive has elastic sliding and slipping, the transmission efficiency is low and the accurate transmission ratio can not be maintained; when the belt pulley drive transmits the same large circumferential force, the profile size and shaft pressure are larger than the meshing drive; the service life of the belt driven by the belt pulley is short. All kinds of mechanical equipment pulley diameter and other dimensions are their own pulley, pulley according to the deceleration ratio, according to the working speed and motor speed design. Working speed / motor speed = diameter of driving pulley / diameter of driven pulley * 0.98 (sliding coefficient). If steel pulley is used, the linear speed shall not be higher than 40m / S; if cast iron pulley is used, the linear speed shall not be higher than 35m / s. conversion ratio between motor speed and pulley diameter: speed ratio = output speed: input speed = pitch circle diameter of load pulley: pitch circle diameter of motor pulley. The pitch diameter and the datum diameter are the same, diameter - 2H = pitch diameter, h is the groove depth on the datum line, different types of V-belt h are different, yzab CDE, the groove depth on the datum line are h = 1.62 2.753.54.88.19.6 respectively. The pitch circle diameter of the belt pulley is the theoretical diameter of the pitch line position of the belt pulley, which is a bit like the pitch circle diameter of the gear. It is generally expressed by PD, and the outer circle is generally expressed by OD. The conversion formula between pitch circle and outer circle of different groove types is different. Generally, it is easier for us to measure the outer circle of the belt pulley, and calculate the pitch circle according to the formula SPZ:OD=PD+4;SPA :OD=PD+5.5; SPB:OD=PD+7;SPC :OD=PD+9.6。 The minimum outer diameter of a or spa pulley is 80mm. If it is smaller than this size, especially at high speed, the belt is prone to delamination and crack at the bottom. SPZ belt, small wheel no less than 63mm. At the same time, pay attention to the installation method and tension of the belt, too small is easy to slip, too large is easy to damage the belt and bearing。
