Abstract

The invention relates to a planetary gearbox capable of directly shifting gears. A cylindrical principal planetary gear at the input end and a cylindrical principal planetary gear at the output end are installed on a planetary rotating shaft through a connection rotating shaft which are fixedly connected with the cylindrical principal planetary gears at the input end and the output end; the cylindrical principal planetary gear at the input end is meshed with a cylindrical sun gear at the input end; the cylindrical principal planetary gear at the output end is meshed with a cylindrical sun gear at the output end; and the planet carrier of the mth planetary transmission modular unit at the front-half transmission mechanism is matched and connected with the planet carrier of the (m+1)th planetary transmission modular unit at the rear-half transmission mechanism through a one-way clutch, or a driving gear fixed on the planet carrier of the mth planetary transmission modular unit and a driven gear fixed on the planet carrier of the (m+1)th planetary transmission modular unit form a mesh transmission. The planetary gearbox are formed by connecting independent planetary transmission modular unit mechanisms in series, can obtain a high transmission ratio, can directly shift gears, and has the advantages of simple structure, low manufacturing cost and easy maintenance.

Description

technical field

[0001] The invention relates to the improvement of the structure of a planetary gear transmission, in particular to a planetary gear gearbox capable of direct gear shifting. Background technique

[0002] As we all know, ordinary planetary gears are composed of sun gears, planetary gears, planetary carriers, and ring gears, and have been widely used in automobiles, textile machinery, mining machinery, construction machinery, and wind power generation devices as reducers and speed increasers. , a reversing mechanism or as a differential of a motor vehicle, because of its complex structure, the conditions for shifting are also relatively high; The radial dimension and axial dimension are reduced, so that the mechanism is compact and the carrying capacity is high. However, the gear shaping process with a gear shaper cutter is the main process in the internal gear mechanic process. The most difficult thing to control is that the variation of the common normal lin...
