One type of slowing tool extensively employed in many mechanical devices is planetary reducer. Its small structure, flawless transmission and great transmission efficiency have benefits. In industrial robotics, automated manufacturing lines, aircraft, rail, transportation, and other sectors it is extensively applied.
Comprising a sun gear, many planetary gears, and an inner ring gear, the planetary reducer is essentially composed of one component. The inner ring gear is attached to the output shaft; the sun gear is attached to the external transmission section via the driving shaft; the planetary gear is situated between the two. The sun gear causes the planetary gear to rotate when the driving shaft rotates; the planetary gear is secured by the inner ring gear to accomplish the deceleration rotation of the output shaft.
Making planetary reducers calls both great technical level and high accuracy. For instance, the meshing accuracy of the inner ring gear and the planetary gear has to be nano level; else, transmission noise and loss will result. Thus, innovative process technology and high-precision processing equipment are needed in the design and production process of the planetary reducer to guarantee the dependability and stability of the product.
Apart from manufacturing accuracy, the choice of material for the planetary reducer is also rather crucial. Usually used for the planetary gear, inner ring gear, and sun gear, the alloy steel materials guarantee their wear durability, corrosion resistance, and great temperature resistance. Simultaneously, the surface of the planetary wheel and the inner ring wheel needs to be hardened to raise their durability and hardness.
It should be mentioned that the operational effect of the planetary reducer will also be influenced by its surroundings. For instance, its components are prone to corrosion and oxidation if it runs in demanding conditions including high temperature, humidity, and corrosion; this will influence it
