Problems solved by technology

[0003] However, in the application field of precision machinery, products require light weight and volume reduction. However, various wires connected to the motor, such as wires and air pipes, are also indispensable components. In the known reducer structure, due to the internal space Without a proper optimized design, these wires must take up additional space for accommodation, resulting in an increase in the overall volume of the reducer, which cannot meet the requirements of the precision machinery field

Embodiment Construction

[0018] The following examples illustrate possible implementations of the present invention, but they are not intended to limit the protection scope of the present invention and are described in advance.

[0019] see Figure 1 to Figure 6 , the one shown is the hollow planetary reducer provided by the present invention, which has a body 1, and the body 1 is provided with a first gear 21, a second gear 31 and a sun gear 32 arranged along the same axis 11 , wherein the first gear 21 and the second gear 31 are located on both sides of the main body 1 respectively, and define a primary reduction mechanism 2 and a secondary reduction mechanism 3 .

[0020] The above-mentioned second gear 31 is an internal gear. In detail, the second gear 31 is an annular structure with teeth on its inner surface. Accordingly, the inner side of the second gear 31 accepts meshing connection with other gears.

[0021] Such as figure 1 , figure 2 match Image 6 As shown, in this embodiment, the ...

Abstract

A hollow planetary reducer comprises a body, wherein the body comprises at least one driving gear, each driving gear is driven by a power input source and connected with a transmission gear, and each transmission gear is connected to a first gear. By the aid of the gear ratio of the driving gears to the transmission gears to the first gear, the speed reduction effect is produced. Besides, a hollow pipe fitting penetrates through the body so as to accommodate wires.

Description

technical field [0001] The invention relates to a reducer, in particular to a hollow planetary reducer. Background technique [0002] At present, in the industrial field, in order to amplify the output torque and improve the output accuracy, various types of reducers are used together. Among them, the planetary reducer is the most common type. Its development technology is mature, the quality is stable, and it is harmonious. Compared with the type reducer, its production cost is low and its transmission efficiency is high, so it is widely used in various industrial machinery. [0003] However, in the application field of precision machinery, products require light weight and volume reduction. However, various wires connected to the motor, such as wires and air pipes, are also indispensable components. In the known reducer structure, due to the internal space Without a proper optimized design, these wires must take up extra space for accommodation, resulting in an increase i...
