中空玻璃設(shè)備變速裝置的作用是改變動(dòng)力機(jī)的輸出轉(zhuǎn)速和轉(zhuǎn)矩以適合執(zhí)行機(jī)構(gòu)的需要。若執(zhí)行機(jī)構(gòu)不需變速時(shí),可采用固定傳動(dòng)的傳動(dòng)系統(tǒng)或采用標(biāo)準(zhǔn)的減速器許多的機(jī)器或設(shè)備要求執(zhí)行機(jī)構(gòu)能夠變速。
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。中空玻璃設(shè)備滑移齒輪變速機(jī)構(gòu),傳動(dòng)系統(tǒng)中某一軸上裝一雙聯(lián)或三聯(lián)可滑移的齒輪(整體式或組合式的結(jié)構(gòu)),通過改變滑移齒輪的嚙合位置,即可獲得不同的各級轉(zhuǎn)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.
滑移齒輪變速機(jī)構(gòu)的特點(diǎn)是:能傳遞較大的轉(zhuǎn)矩和轉(zhuǎn)速;變速較方便、可靠。但是,滑移齒輪不能在運(yùn)轉(zhuǎn)中變速,為便于嚙合,多采用直齒齒輪傳動(dòng),因而傳動(dòng)不夠平穩(wěn)且噪音較大。
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。中空玻璃設(shè)備離合器變速機(jī)構(gòu),離合器變速機(jī)構(gòu)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(dòng),傳動(dòng)比準(zhǔn)確,可傳遞較大的轉(zhuǎn)矩,但不能在運(yùn)轉(zhuǎn)中變速。
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。中空玻璃設(shè)備交換齒輪變速機(jī)構(gòu),高精度絲杠車床中的齒輪就是交換齒輪的變速機(jī)構(gòu),變速交換齒輪機(jī)構(gòu)的特點(diǎn)是:結(jié)構(gòu)簡單,不需要變速操縱機(jī)構(gòu);與滑移齒輪變速相比,實(shí)現(xiàn)同樣的變速級數(shù)所用的齒輪數(shù)量少。但是,更換齒輪時(shí)費(fèi)時(shí)費(fèi)力,交換齒輪是懸臂式結(jié)構(gòu),剛性和潤滑條件差。因此,它適于不經(jīng)常變速的設(shè)備。
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.
