一、概述 (一)行星齿轮传动的优点行星齿轮传动的优越性,突出地表现在体积小、重量轻、效率高、使用寿命长。据有关统计资料,2K—H型行星减速器与普通减速器相比,重量仅为其25～55％,体积约为15～60％。而在行星传动中,随着行星轮的增多,其结构更为紧凑(见图1),重量随之减轻,在相同的额定功率和速比的情况下,四行星轮装置的外形尺寸,仅为单行星轮的一半。在同样尺寸的情况下,其所传递的力矩为平行轴线的齿轮传动(即普通传动)的5倍。传动比大,2K—H型的行星传动,单级传动比i=1.14
I. Overview (A) the advantages of planetary gear The superiority of planetary gear drive, prominently in the small size, light weight, high efficiency, long service life. According to statistics, 2K-H planetary gear reducer compared with ordinary, the weight of only 25 to 55%, the volume is about 15 to 60%. In the planetary transmission, with the increase of the planetary gear, the structure is more compact (see Figure 1), the weight is reduced, with the same rated power and speed ratio case, four planetary gear device dimensions, only Half of a single-star wheel. In the case of the same size, it transmits the torque of parallel axis gear drive (ie, ordinary transmission) 5 times. Transmission ratio, 2K-H-type planetary transmission, single-stage transmission ratio i = 1.14
