一种行星齿轮变速机构
摘要：
本实用新型公开了一种行星齿轮变速机构，它主要包括输出轴、壳体、行星轮架、销轴、行星轮、内齿圈、太阳轮、固定齿轮、输入轴和手动操作换挡机构。行星轮通过销轴安装在行星轮架上；当换挡机构将内齿圈与固定齿轮啮合在一起时，内齿圈固定，太阳轮、行星轮、内齿圈、行星轮架组成一行星减速机构，减速比由太阳轮齿数、行星轮齿数、内齿圈齿数决定，形成1挡；当换挡机构将内齿圈处于中位时，内齿圈不固定，形成空挡；当换挡机构将内齿圈与行星轮架啮合在一起时，太阳轮、行星轮、内齿圈、行星轮架连接成一体，形成直接传动，减速比为1，形成2挡。本实用新型可以解决对于小型2挡行星齿轮实现成本低、易于实现，且高可靠性要求的技术问题。
摘要（英）：

The utility model discloses a planetary transmission mechanism, which mainly comprises an output shaft, a shell, a planet carrier, a pin shaft, a planet gear, an inner gear ring, a sun gear, a fixed gear, an input shaft and a manually-operated gearshift mechanism, wherein the planet gear is arranged on the planet carrier through the pin shaft; when the inner gear ring and the fixed gear are meshed through the gearshift mechanism, the inner gear ring is fixed, the sun gear, the planet gear, the inner gear ring and the planet carrier form a planetary reduction mechanism, a reduction ratio is determined by the tooth numbers of the sun gear, the planet gear and the inner gear ring, and a first gear is formed; when the gearshift mechanism is positioned at the neutral position of the inner gear ring, the inner gear ring is unfixed, and a neutral gear is formed; and when the inner gear ring and the planet carrier are meshed through the gearshift mechanism, the sun gear, the planet gear, the inner gear ring and the planet carrier are connected into a whole to form direct transmission, a reduction ratio is 1, and a second gear is formed. A miniature two-gear planet gear is low in cost, easy to implement and high in reliability.
