Example Embodiment

The present invention mainly includes a casing, an input shaft, an output shaft, a boom bracket and related gears installed in the casing. It differs from the prior art in that: the boom brackets 5 and 6 are fixedly connected to the planetary gear shaft 7; the input shaft 9 is fixedly connected to the boom bracket; there is a circular aperture in the middle of the boom bracket 6, which passes through the gear 1 and Positioned on the housing 10 through bearings; gear 2 and gear 3 are fixedly connected, they are planetary gears, the planetary gear is equipped with a bearing 8 in the middle, and then positioned on the planetary gear shaft 7; the gear 1 is fixedly connected to the housing 10, input The shaft 11 passes through the circular aperture in the gear 1, and the output shaft 11 is fixedly connected to the gear 4;

Gear 2 meshes with gear 1; gear 3 meshes with gear 4; bearings are installed where the output shaft and input shaft are connected to the housing.

Abstract

A direct driving (outer engaging) gear speed reducer, only adjusting the diameter ratio of two gears, various transmission ratio from tens to tens of thousands, in any transmission ratio, every gear driving output axle in minimum friction coefficient all the time, the loaded force in each gear is uniform by driving planetary gear set in accurate position. Said invention also can be used as speed increaser with increased bearing ability, simple structure, small volume and light weight.

Description

Technical field: The present invention relates to the technical field of speed reducer, because it is directly driven by lever arm balancing gravity, and all adopt external gear drive, so specifically it is a kind of "direct acting (external gear) gear reducer". Background technique: In the existing technical field, the harmonic drive reducer is a high-ratio reducer, and its first-stage retrieval transmission ratio can reach 500 revolutions per revolution, so it has a wide application prospect in high-ratio reduction equipment . But it also has some problems. There are related information: When the transmission ratio of the harmonic transmission reducer is tens of revolutions per revolution, its transmission efficiency is 90%. It has a transmission efficiency of 70%. Invention content: The object of the present invention is to provide a "direct-acting (external gear) gear reducer", which can overcome some deficiencies in the prior art. At the same time, compared with ...
