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。
The function of the transmission of the hollow glass equipment is to change the output speed and torque of the power machine to fit the needs of the actuator. If the actuator does not need to change speed, a fixed transmission system or a standard reducer can be used. Many machines or devices require the actuator to change speed.
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。
1. The sliding gear transmission mechanism of the hollow glass equipment is equipped with one or two triplex sliding gears (integral or combined structure) in the transmission system. By changing the engaging position of the sliding gears, different speeds can be obtained.
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。
The characteristic of sliding gear transmission mechanism is that it can transmit large torque and speed, and the speed change is more convenient and reliable. However, the sliding gear can not be changed during the operation. In order to facilitate the meshing, the gear transmission is mostly used, so the transmission is not stable enough and the noise is large.
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 has teeth inlay, gear type, friction disc type clutch. The embedded clutch and gear clutch are rigid transmission, and the transmission ratio is accurate, which can transmit large torque, but it can not be changed in 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. Gear exchange hollow glass equipment, gear precision screw lathe gear in gear transmission characteristics is to exchange, exchange gear mechanism has the advantages of simple structure, does not need the transmission mechanism; compared with sliding gear transmission, to achieve the same speed series with fewer gears. However, it takes time and effort to replace the gear, and the exchange gear is a cantilever structure, and the rigidity and the lubrication condition are poor. Therefore, it is suitable for equipment that does not change regularly.
