Abstract

The invention relates to planetary variable transmission mechanisms, in particular to a planetary continuously variable transmission mechanism and belongs to the technical field of variable transmission. The planetary continuously variable transmission mechanism comprises a sun gear, an inner planetary gear, a planet carrier, planet gear shafts, outer planetary gears, a driving mechanism and an internal gear. A plurality of planet gear shafts are uniformly arranged on the planet carrier in the circumferential direction, both ends of every planet gear shaft are respectively connected to one inner planetary gear and at least one group of the outer planetary gears, the driving mechanism is arranged outside the planet carrier, the output end of the driving mechanism is connected to the center position of the outside of the planet carrier, and the output end of the the driving mechanism can drive the planet carrier to rotate around the center. According to the planetary continuously variable transmission mechanism, the internal gear is driven by the driving mechanism to rotate, and the purpose of controlling the transmission ratio of the whole transmission system is achieved by controlling the rotational speed of the outer gear, so that continuously variable transmission in a certain range is achieved.

Description

technical field [0001] The invention relates to a planetary speed change mechanism, specifically a planetary stepless speed change mechanism, belonging to the technical field of speed change transmission. Background technique [0002] The planetary variable transmission mechanism consists of planetary gears (multiple planetary gears mounted on a rigid planetary carrier), sun gear and ring gear (outer gear), usually corresponding to the input shaft, output shaft and frame (fixed reference frame ), for a general planetary transmission mechanism, there is always a gear, such as the outer wheel is fixed, so that the transmission ratio of the other two gear shafts is also fixed, if you want to achieve speed change in such a mechanism, you must consider increasing the transmission route, and then add variable parts in the transmission route to achieve the purpose of speed change. Increasing the transmission route will increase the structural complexity, increase the structural we...
