中空玻璃設備變速裝置的作用，中空玻璃設備變速裝置的作用是改變動力機的輸出轉速和轉矩以適合執行機構的需要。若執行機構不需變速時，可采用固定傳動的傳動系統或采用標準的減速器許多的機器或設備要求執行機構能夠變速。如采煤機在不同工作條件和不同煤層厚度時，應能改變牽引速度;推土機在不同工況下應能改變行駛速度;通用的機床要求主運動和進給運動能在較大范圍內變速，以適應加工廣泛性(不同直徑、材料、工序、精度、表面質量)的要求。

The function of the variable speed device for insulated glass equipment is to change the output speed and torque of the power machine to meet the needs of the actuator. If the actuator does not require variable speed, a fixed transmission system or a standard reducer can be used. Many machines or equipment require the actuator to be able to change speed. When the coal mining machine operates under different working conditions and coal seam thicknesses, it should be able to change the traction speed; The bulldozer should be able to change its driving speed under different working conditions; Universal machine tools require the main and feed movements to be able to change speed over a wide range to meet the requirements of machining versatility (different diameters, materials, processes, accuracy, surface quality).

對中空玻璃設備變速裝置的基本要求是：能傳遞足夠的功率和轉速;較高的傳動效率;滿足變速范圍和變速級數的要求;體積小、重量輕;噪音在允許的范圍內;結構簡單，制造、測量、裝配和維修的工藝性好;潤滑和密封性良好，能防止“三漏”(漏油、漏氣、漏水)現象。

The basic requirements for the variable speed device of insulated glass equipment are: it can transmit sufficient power and speed; High transmission efficiency; Meet the requirements of variable speed range and variable speed stages; Small in size and light in weight; The noise is within the allowable range; Simple structure, good craftsmanship in manufacturing, measurement, assembly, and maintenance; Good lubrication and sealing can prevent the phenomenon of "three leaks" (oil leakage, air leakage, water leakage).

中空玻璃設備傳動件的尺寸決定于傳遞的轉矩。當傳遞功率一定時，傳動件的轉速愈高，傳遞的轉矩愈小，傳動機構的結構尺寸就可小一些。常用的變速裝置有以下幾種：

The size of the transmission components of insulated glass equipment is determined by the transmitted torque. When the transmitted power is constant, the higher the speed of the transmission component, the smaller the transmitted torque, and the smaller the structural size of the transmission mechanism. There are several commonly used variable speed devices:

1.中空玻璃設備滑移齒輪變速機構，傳動系統中某一軸上裝一雙聯或三聯可滑移的齒輪(整體式或組合式的結構)，通過改變滑移齒輪的嚙合位置，即可獲得不同的各級轉速。滑移齒輪變速機構的特點是：能傳遞較大的轉矩和轉速;變速較方便、可靠。但是，滑移齒輪不能在運轉中變速，為便于嚙合，多采用直齒齒輪傳動，因而傳動不夠平穩且噪音較大。

1. The sliding gear variable speed mechanism of insulated glass equipment is equipped with a double or triple sliding gear (integral or combination structure) on a certain shaft in the transmission system. By changing the meshing position of the sliding gear, different levels of rotational speed can be obtained. The characteristics of slip gear transmission mechanism are: it can transmit large torque and speed; Variable speed is more convenient and reliable. However, sliding gears cannot change speed during operation. In order to facilitate meshing, spur gear transmission is often used, resulting in unstable transmission and high noise.

2.中空玻璃設備離合器變速機構，離合器變速機構有牙嵌式、齒輪式、摩擦片式離合器。牙嵌式離合器和齒輪式離合器屬于剛性傳動，傳動比準確，可傳遞較大的轉矩，但不能在運轉中變速。

2. Hollow glass equipment clutch transmission mechanism, clutch transmission mechanism includes tooth embedded, gear type, and friction plate type clutches. Tooth embedded clutch and gear clutch belong to rigid transmission, with accurate transmission ratio and the ability to transmit large torque, but cannot change speed during operation.

3.中空玻璃設備交換齒輪變速機構，高精度絲杠車床中的齒輪就是交換齒輪的變速機構，變速交換齒輪機構的特點是：結構簡單，不需要變速操縱機構;與滑移齒輪變速相比，實現同樣的變速級數所用的齒輪數量少。但是，更換齒輪時費時費力，交換齒輪是懸臂式結構，剛性和潤滑條件差。因此，它適于不經常變速的設備。

3. Hollow glass equipment exchange gear speed mechanism, the gears in high-precision screw lathe are the exchange gear speed mechanism, and the characteristics of the exchange gear mechanism are: simple structure, no need for speed control mechanism; Compared to slip gear speed change, the number of gears used to achieve the same speed change stage is less. However, replacing gears is time-consuming and labor-intensive, and the gear exchange is a cantilever structure with poor rigidity and lubrication conditions. Therefore, it is suitable for devices that do not frequently change gears.
