Background

A planetary gear transmission refers to a gear transmission in which the axis of one or more gears revolves around the fixed axis of another gear. The planet wheel not only rotates around the axis of the planet wheel, but also rotates around a fixed axis along with the planet carrier. The planetary gear transmission is mainly characterized by small volume, large bearing capacity and stable work; however, the high-power high-speed planetary gear transmission structure is complex and requires high manufacturing precision. Some types of planetary gear transmissions are efficient, but the transmission ratio is not large. Other types may have very large transmission ratios but are inefficient, and when they are used as reducers, their efficiency decreases with increasing transmission ratio; when used as a speed increaser, self-locking can be generated. The differential gear train can combine two given movements or can decompose one given movement into the movements of two basic elements according to requirements. An example of a split motion is an automotive differential. The planetary gear transmission has wide application, can be used together with a continuously variable transmission, a hydraulic coupler, a hydraulic torque converter and the like, and further expands the application range. The existing NGWN type planetary gear reducer generally comprises a four-corner contact bearing assembly formed by a first inner gear ring, a bearing ring coaxially fixed with the first inner gear ring, a second inner gear ring, a steel ball and a steel ball isolation column positioned between the first inner gear ring and the bearing ring, wherein the first inner gear ring and the second inner gear ring in the four-corner contact bearing assembly are respectively meshed with a large gear and a small gear in a conjoined dual gear structure, the structure is complex, the transmission stability is poor, the installation is inconvenient, and the general NGWN type planetary gear reducer is large in overall size, cannot be miniaturized, poor in sealing performance, easily contaminated by oil stains and difficult to clean. Therefore, an NGWN planetary transmission structure is provided.
