日本右川播磨重工公司最近开发了内部设有逆转装置的行星齿轮减速器,它可用作渔船和内河船舶推进器的减速装置。过去只知道复式多级行星机构可以实现正反转,而石播开发的减速器采用带有惰轮的单级行星机构来完成逆转。其结构特点是:行星轮的支承轴是固定的,太阳轮输入,内齿轮输出;该装置有前进用和后退用两个太阳轮,前进用太阳轮与行星轮直接啮合,而后退用太阳轮需经惰轮与行星轮啮合;正逆转的交替
Toyo Heavy Industries, Japan, has recently developed a planetary gear reducer with a reversing mechanism inside, which can be used as a decelerator for fishing vessels and inland vessel thrusters. In the past, it was only known that the compound multistage planetary gear could achieve positive and negative rotation, while the stone gear developed gear reducer used the single-stage planetary gear with idler gear to complete the reversal. Its structure is characterized by: the planetary gear support shaft is fixed, the sun gear input, the internal gear output; the device has forward and backward with two sun wheels, forward with the sun gear meshing directly with the planets, and back with the sun gear To be engaged by the idler and planetary wheel; is reversing the turn
