Abstract

The invention discloses a hydraulic power speed increaser which comprises a speed increasing box, a planetary gear set, impellers and a rotating shaft. The speed increasing box comprises an upper shell and a lower shell, and the upper shell and the lower shell are provided with a set of hydraulic push rods with opposite pushing directions. The upper shell and the lower shell are each provided with an annular groove, the corresponding annular impeller is embedded in each annular groove, and each hydraulic push rod pushes the corresponding impeller to rotate in the same direction. The impellers are provided with outer teeth and inner teeth. The outer teeth are engaged with the hydraulic push rods through a rack. The inner teeth are engaged with the planetary gear set, the planetary gear set drives the rotating shaft to rotate at a variable speed, and a bearing of the rotating shaft is arranged on the upper shell and the lower shell. The hydraulic power speed increaser mainly depends on an oil cylinder hydraulic system serving as main power to push the high-precision rack to do repeated circulation action in the clockwise direction, the outer teeth of the impellers are pushed through the rack, meanwhile, the inner teeth drive the planetary gear set to achieve gear ratio speed increasing, and due to energy conversion of a hydraulic oil cylinder, the hydraulic power speed increaser has the advantages of being large in driving torque, low in complete machine power, high in rated pressure and the like.

Description

technical field

[0001] The invention relates to the technical field of speed increasers, in particular to a hydraulic power speed increaser. Background technique

[0002] The speed increaser is an important part of complete sets of equipment for wind power generation, aircraft, and hydraulic high-pressure plunger pumps. However, at present, the speed increasers at home and abroad all use the motor structure, and the speed increase ratio is small, so that the driving torque cannot meet the demand. Contents of the invention

[0003] In order to solve the above problems, the object of the present invention is to provide a hydraulic power speed increaser that is driven by hydraulic pressure and utilizes a planetary gear set to increase the gear ratio.

[0004] The purpose of the present invention adopts following technical scheme to realize:

[0005] A hydraulic power speed increaser, including a speed increaser, a planetary gear set, an impeller and a rotating shaft, the sp...
