The role of the hollow glass equipment variable speed device, the role of the hollow glass equipment variable speed device is to change the output speed and torque of the power machine to suit the needs of the actuator. If the actuator does not need to change speed, a fixed transmission transmission system or a standard reducer can be used. Many machines or equipment require the actuator to be able to change speed. For example, the shearer should be able to change the traction speed under different working conditions and the thickness of the coal seam; the bulldozer should be able to change the driving speed under different working conditions; the general machine tool requires the main movement and the feed movement to be variable in a larger range. In order to meet the requirements of processing versatility (different diameters, materials, procedures, precision, surface quality).
The basic requirements for the variable speed device of the insulating glass equipment are: can transmit enough power and speed; higher transmission efficiency; meet the requirements of variable speed range and speed range; small size and light weight; noise within the allowable range; simple structure , Good manufacturability in manufacturing, measurement, assembly and maintenance; good lubrication and sealing, which can prevent "three leaks" (oil, air, and water leakage).
The size of the transmission part of the hollow glass equipment is determined by the transmitted torque. When the transmission power is constant, the higher the rotation speed of the transmission member, the smaller the transmission torque, and the structural size of the transmission mechanism can be smaller. The commonly used speed change devices are as follows:
1. Insulating glass equipment sliding gear transmission mechanism, a double or triple sliding gear (integral or combined structure) is installed on a certain shaft of the transmission system, and the difference can be obtained by changing the meshing position of the sliding gear Speed at all levels. The characteristics of the sliding gear transmission mechanism are: it can transmit larger torque and speed; the speed change is more convenient and reliable. However, the sliding gear cannot change speed during operation. In order to facilitate meshing, spur gears are often used for transmission, so the transmission is not stable enough and the noise is large.
2. Insulating glass equipment clutch transmission mechanism. The clutch transmission mechanism includes jaw type, gear type and friction plate type clutch. Jaw clutches and gear clutches are rigid transmissions, with accurate transmission ratios, which can transmit large torques, but cannot change gears during operation.
3. Insulating glass equipment exchange gear transmission mechanism, the gear in the high-precision screw lathe is the transmission mechanism of the exchange gear. The characteristics of the transmission exchange gear mechanism are: simple structure, no transmission operation mechanism; compared with slip gear transmission, The number of gears used to achieve the same number of gear shifts is small. However, it is time-consuming and laborious to replace the gears. The replacement gears have a cantilever structure, which has poor rigidity and lubrication conditions. Therefore, it is suitable for equipment that does not frequently change gears.
