Novel planetary reducer

Abstract

The invention discloses a novel planetary reducer. The novel planetary reducer comprises a common sun gear, a planetary gear I, an inner gear ring I, a planetary gear II, a planet carrier and an innergear ring II which are fixed on a middle shaft, wherein the common sun gear is arranged inside the planet carrier, the common sun gear is externally meshed with the first planetary gear and the second planetary gear at the same time, the planetary gear I and the planetary gear II are rotationally arranged on the planet carrier through a rotating shaft, the planetary gear I is internally meshed with the inner gear ring I, the planetary gear II is internally meshed with the inner gear ring II, the inner gear ring I is fixed in position, and the inner gear ring II is arranged on one side of theinner gear ring I. The novel planetary reducer is convenient to machine, good in operation stability, high in machining precision and low in working noise.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a novel planetary speed reducer. Background technique [0002] The principle of the NGWN planetary reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism. The gear with a small number of teeth on the transmission shaft of the planetary reducer meshes with the large gear on the output shaft to achieve the purpose of deceleration. In the existing NGWN technology, the dual planetary gear has high requirements on the position of the two gear teeth, because the axial distance between the two gears Recently, when the number of teeth and the modulus are different, there will be interference when grinding the gears, so the gears cannot be ground, and the teeth can only be processed simultaneously by shaping, which has low machining accuracy and high operating no...

The gear with a small number of teeth on the transmission shaft of the planetary reducer meshes with the large gear on the output shaft to achieve the purpose of deceleration. In the existing NGWN technology, the dual planetary gear has high requirements on the position of the two gear teeth, because the axial distance between the two gears Closer, when the number of teeth and the modulus are different, there will be interference when grinding the teeth, so it is impossible to grind the teeth, and can only be processed at the same time by shaping the teeth, the machining accuracy is low, and the running noise is large
