Gear transmission structure with mute and low abrasion

Abstract

The invention discloses a gear transmission structure with mute and low abrasion. The gear transmission structure with mute and low abrasion comprises an output shaft and an input shaft, a gear ring is connected to the output shaft, the gear ring is of an annular structure, and a plurality of evenly distributed output gear teeth are arranged on the inner wall of the gear ring; an input gear is connected to the input shaft, and the input gear meshes with three same planet gears, the three planet gears mesh with the gear ring simultaneously, the gear ring is externally sleeved with a sound proof box, through holes are formed in the two sides of the sound proof box correspondingly, and the input shaft and the output shaft extends out of the through holes correspondingly; both the input gear and the planet gears comprise hubs, wheel discs, gear teeth and gear grooves, an annular oil tank is arranged outside of each hub, the annular oil tank is nested in the corresponding wheel disc, and an oil injecting opening is formed in the surface of each annular oil tank, a plurality of small holes are evenly distributed on the outer wall of the ring face of each annular oil tank, the small holes are connected with the gear grooves through wee oil ducts. The gear transmission structure with mute and low abrasion can achieve the mute effect while abrasion is lowered and is a good choice for transmission gears.

Description

technical field [0001] The invention relates to the technical field of gear structures, in particular to a quiet and low-wear gear transmission structure. Background technique [0002] Gear transmission is the most widely used form of transmission in mechanical transmission. Its transmission is relatively accurate, high in efficiency, compact in structure, reliable in operation and long in life. Transmission, according to the relative position of the gear axis, is divided into parallel shaft cylindrical gear transmission, intersecting shaft bevel gear transmission and cross shaft helical gear transmission. These transmission forms have provided great help to modern mechanical manufacturing and enriched our lives. [0003] However, the common gear transmission will encounter the following problems. First, the meshing method often directly adopts the meshing between gears, which will take up a lot of space, so it is difficult to eliminate noise; It is added directly from the ...

Problems solved by technology

[0003] However, the common gear transmission will encounter the following problems. First, the meshing method often directly adopts the meshing between gears, which will take up a lot of space, so it is difficult to eliminate noise; Add directly from the outside, so that most of the lubricating oil will be separated due to centrifugal force when the gear rotates, which cannot effectively reduce friction. In order to solve these problems, a silent and low-wear gear transmission structure is designed.
