渐开线少齿差行星减速装置(即K—H—V传动)在起重机械中的应用,在我国约有20年的历史,这种减速装置具有下列特点: (1)速比大。一级速比最大可到100左右,二级速比可达1万; (2)结构紧凑,体积小,重量轻。如果参数选得合理,设计得好,体积和重量可减小到JZQ型减速器的2/3～1/2。(3)效率高。经我们实测,如加工精度达到八级精度,速比在50～80范围内,效率可 Involute less tooth difference planetary reducer (ie, K-H-V drive) in the crane application, about 20 years of history in our country, this deceleration device has the following characteristics: (1) large speed ratio. A speed ratio up to about 100, two speed ratio up to 10,000; (2) compact structure, small size, light weight. If the parameters are selected properly, well designed, the volume and weight can be reduced to 2/3 ~ 1/2 of JZQ type reducer. (3) high efficiency. After we measured, such as precision machining reached eight precision, speed ratio in the range of 50 to 80, the efficiency can be
