Abstract

The invention provides an inner gear ring, a driving assembly with the inner gear ring and application equipment applying the driving assembly. The inner gear ring comprises two or more gear ring bodies, wherein the gear ring bodies are arranged on the inner wall of a same shell in a parallel manner, and every two adjacent gear ring bodies are arranged to form a certain angle. According to the inner gear ring and the driving assembly, the two or more gear ring bodies are arranged on the inner wall of the same shell, so that high concentricity and high stability are achieved, and thus noise generated by a driving mechanism is reduced; and in addition, the inner gear ring and the driving assembly are easy to assemble and low in manufacturing cost.

Description

【Technical field】 [0001] The present invention relates to drive assemblies, and more particularly, to drive assemblies with internal ring gears. 【Background technique】 [0002] The power drive mechanism with a reduction gearbox is used in many occasions, for example, it is used to drive an automatic lawnmower. When the reduction gear box runs at high speed, it will generate relatively loud noise, which will cause noise pollution to the surrounding environment. Therefore, how to reduce the noise of the reduction gearbox as much as possible is an urgent problem to be solved. 【Content of invention】 [0003] In view of this, the present invention provides an inner ring gear, which includes at least two ring gears arranged in parallel on the inner wall of the same housing, and adjacent ring gears are arranged at a certain angle. [0004] Preferably, the gear ring includes a helical gear gear and a straight gear gear; the helical gear gear is arranged at an oblique angle to th...
