Abstract

The invention discloses a planetary gear speed increaser. The planetary gear speed increaser comprises a host box body; the upper portion of the host box body is provided with a host upper cover which is connected with an input main shaft; an inner casing pipe and an outer casing pipe sleeve the input main shaft in turn; a rotation supporting device is arranged between the inner casing pipe and the outer casing pipe; a gear ring fixing plate which is connected with the inner casing pipe is arranged in the host box body; the gear ring fixing plate is connected with an inner gear ring; a planetary gear shaft is fixedly arranged at the bottom in the host box body; the planetary gear shaft is provided with a planetary gear which is in constant mesh with the inner gear ring; a sun pinion is arranged in the host box body; the sun pinion is in constant mesh with the planetary gear and is connected with an output shaft. According to the planetary gear speed increaser, the speed increase effect is achieved through the planetary gear, the staring torque is small, the structure is compact, the size is small, the transmission is stable, the work noise is small, and the rotating speed is effectively improved.

Description

technical field [0001] The invention relates to a speed increaser, in particular to a planetary gear speed increaser. Background technique [0002] In the prior art, planetary gears are mainly used in reducers, and their main features are small size, large load capacity, and stable operation. However, when planetary gears are used in speed-up applications, there is a problem of excessive starting torque, which is difficult to achieve. ideal purpose. Vertical axis wind turbines are more and more widely used due to the use of wind energy to generate energy, save energy and protect the environment. However, due to the problems of sweeping angle and wind pressure of the blades of vertical axis wind turbines, the maximum speed is 40r / min, and the power generation is insufficient. At this time, it is necessary to increase the rotation speed of the generator to increase the power generation, so as to ensure that the design power is in line with the actual situation. The ordinary s...
