中空玻璃设备变速装置的作用，中空玻璃设备变速装置的作用是改变动力机的输出转速和转矩以适合执行机构的需要。若执行机构不需变速时，可采用固定传动的传动系统或采用标准的减速器许多的机器或设备要求执行机构能够变速。如采煤机在不同工作条件和不同煤层厚度时，应能改变牵引速度;推土机在不同工况下应能改变行驶速度;通用的机床要求主运动和进给运动能在较大范围内变速，以适应加工广泛性(不同直径、材料、工序、精度、表面质量)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).

对中空玻璃设备变速装置的基本要求是：能传递足够的功率和转速;较高的传动效率;满足变速范围和变速级数的要求;体积小、重量轻;噪音在允许的范围内;结构简单，制造、测量、装配和维修的工艺性好;润滑和密封性良好，能防止“三漏”(漏油、漏气、漏水)现象。

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).

中空玻璃设备传动件的尺寸决定于传递的转矩。当传递功率一定时，传动件的转速愈高，传递的转矩愈小，传动机构的结构尺寸就可小一些。常用的变速装置有以下几种：

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.中空玻璃设备滑移齿轮变速机构，传动系统中某一轴上装一双联或三联可滑移的齿轮(整体式或组合式的结构)，通过改变滑移齿轮的啮合位置，即可获得不同的各级转速。滑移齿轮变速机构的特点是：能传递较大的转矩和转速;变速较方便、可靠。但是，滑移齿轮不能在运转中变速，为便于啮合，多采用直齿齿轮传动，因而传动不够平稳且噪音较大。

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.中空玻璃设备离合器变速机构，离合器变速机构有牙嵌式、齿轮式、摩擦片式离合器。牙嵌式离合器和齿轮式离合器属于刚性传动，传动比准确，可传递较大的转矩，但不能在运转中变速。

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.中空玻璃设备交换齿轮变速机构，高精度丝杠车床中的齿轮就是交换齿轮的变速机构，变速交换齿轮机构的特点是：结构简单，不需要变速操纵机构;与滑移齿轮变速相比，实现同样的变速级数所用的齿轮数量少。但是，更换齿轮时费时费力，交换齿轮是悬臂式结构，刚性和润滑条件差。因此，它适于不经常变速的设备。

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.
