Abstract
The utility model discloses a transmission comprising a sun gear, primary planetary gears which are lined along the periphery of the sun gear, secondary planetary gears which are lined along the periphery of the primary planetary gears and an inner gear of an outer ring. The primary and the secondary planetary gears are fixed on the same planetary carrier; the sun gear is meshed with the primary planetary gears, and the primary planetary gears are respectively meshed with the secondary planetary gears on the periphery thereof; and the inner gear and the planetary carrier output power on demand. The transmission has the advantages of high transmission efficiency, good stability, long service life, a multi-stage gear power transmission method and the like.
Description
Technical field
The utility model relates to the speed change gear in a kind of mechanical transmission.
Background technique
Existing automatic gearbox of vehicles need possess forward and reverse and slow down, quickens the function of output, and traditional plane table thermoconductivity meter only has a sun gear and one group of planet wheel, and it is unsuitable for being applied in the automatic transmission case of automobile.
Summary of the invention
The purpose of this utility model provides a kind of speed changer, adapts to the technical problem that automatic gearbox of vehicles is forward and reverse and speed change is exported to solve.
A kind of speed changer described in the utility model comprises: sun gear, the one-level planet wheel of arranging along sun gear periphery, the secondary planet wheel of arranging along one-level planet wheel periphery and the internal gear of outer ring.Described one-level planet wheel, secondary planet wheel are fixed on the same planet carrier, described sun gear and the engagement of one-level planet wheel, the secondary planet wheel engagement that the one-level planet wheel is peripheral with it respectively; Described internal gear and planet carrier be outputting power as required.
The utlity model has advantages such as transmission efficiency height, good stability, long service life and multi-stage gear power transmission mode.
