Abstract
The utility model discloses a planetary gear mechanism, which includes a connecting disc, wherein a barrel-shaped casing is integrally cast and formed on the upper surface of the connecting disc, and a hollow cavity is formed between the barrel-shaped casing and the connecting disc; a plurality of notches are arranged respectively at the joint part of the barrel-shaped casing and the connecting disc; and included angles between every two adjacent notches are the same; mounting holes are respectively arranged between the adjacent openings and on the barrel-shaped casing; a through hole is arranged at the central part of the barrel-shaped casing; a sun wheel is mounted in the through hole and a transmission shaft is mounted at the central part of the sun wheel; planetary wheels are rotationally mounted around the sun wheel respectively; the sun wheel is meshed with the planetary wheels around the sun wheel respectively; and the outer sides of the planetary wheels protrude from the plurality of notches and are meshed with inner teeth of a floating ring gear sleeved outside the barrel-shaped casing. The planetary gear mechanism has the characteristics of compact structure, small size and light weight, and has high bearing capacity and long service life, is stable in operation and low in noise, is simple and easy to machine and assemble, occupies small space, and has an excellent use value.
Description
Technical field
The utility model relates to a kind of planetary gears.
Background technique
Planet is as the term suggests be exactly to rotate around fixed star, so planetary gears is exactly like this, has two planet wheels to center on the retarder of a sun gear rotational structure.
Planetary gears is a kind of broad-spectrum industrial products, and its performance can compare favourably with other army's grade planetary gears product, and the price of technical grade product is but arranged, and is applied to the wide industrial occasion.
Planetary gears has power dividing, the private characteristic of multiple tooth engagement.Maximal input can reach 104kW.Be applicable to that industrial department planets such as lifting transportation, engineering machinery, metallurgy, mine, petrochemical industry, building machinery, industry light industry textile industry, medical apparatus, instrument and apparatus, automobile, boats and ships, weapons and Aero-Space series new varieties WGN ordinary transmission retarder, WN primary and secondary gear transmission retarder, elasticity all carry little tooth difference speed reducer.
Planetary gears also can be used as matching parts and is used for industries such as lifting, excavation, transportation, building.
The model utility content
The purpose of the utility model provides a kind of planetary gears, is installed in some device interiors, is used for power transmission.
