齿轮传动仍是目前最普通的一种传动方式,它与新兴的液压传动相比,仍以其传动效率高,使用寿命长、工作安全可靠,对密封要求不高,加工成本低等显著的优点,在建筑机械设备传动中占为首位。我国百分之八十以上的建筑机械仍以齿轮传动为主。但在大量使用中,由于磨损而报废的齿轮数量相当大。因此,减少油料消耗,降低齿轮的磨损速度,合理地选用润滑剂,是提高齿轮使用寿命的有效措施之一。虽然齿轮的润滑剂品种较多,但建筑机械、起重机械的齿轮主要是采取润滑油润滑,尤其是各种封闭式齿轮传动装置(即减速器),一般都是采用油池飞溅式润滑。一般采用40号、50号、70号、90号机械油和20号、30号齿轮油及24号汽缸油等。由于机械设备的润滑与密封装置存在某些缺陷,设备在长期运转中,尤
Gear transmission is still the most common transmission method at present. Compared with the emerging hydraulic transmission, it still has high transmission efficiency, long service life, safe and reliable work, low requirements for sealing, low processing cost, and other significant advantages. In the construction machinery and equipment transmission accounted for the first. More than 80 percent of China’s construction machinery is still gear-driven. However, in heavy use, the number of scrapped gears due to wear is considerable. Therefore, reducing oil consumption, reducing the wear rate of gears, and selecting lubricants reasonably are one of the effective measures to improve the service life of gears. Although there are many kinds of gear lubricants, the gears of construction machinery and hoisting machinery are mainly lubricated with lubricating oil. In particular, all kinds of closed gear transmissions (reducers) are usually splash-lubricated. Generally, No.40, No.50, No.70, No.90 mechanical oil, No.20, No.30 gear oil and No.24 cylinder oil are used. Due to certain deficiencies in the lubrication and sealing of mechanical equipment, the equipment is in operation for a long time, especially
