Abstract

The invention discloses a separating flexible speed increasing device based on an inner-curve hydraulic motor. The separating flexible speed increasing device based on the inner-curve hydraulic motor comprises a fan, the inner-curve hydraulic motor, a high-pressure end energy accumulator, a one-way valve, an overflow valve, a throttling valve, a hydraulic pipe, a hydraulic motor set, a power generator unit and an oil tank, wherein the inner-curve hydraulic motor is connected with the hydraulic motor and is arranged above a tower frame, and other devices are arranged below the tower frame. The inner-curve hydraulic motor of the invention belongs to a low-speed large-torsion motor, and is also used as a hydraulic pump. The inner-curve hydraulic motor has the characteristics of low speed and large torsion, requirements on wind power utilization are met, working condition of a wind-power machine is adapted, transmission of wind power is convenient, a speed increasing device of a large wind-power system is simplified, the load of the top of the tower frame is reduced, maintenance and installation are convenient and the development cost is reduced.

Description

Technical field [0001] The invention relates to a separate flexible speed increasing device used in a large-scale wind power system, in particular to a separate flexible speed increasing device realized by using the characteristics of an inner curve hydraulic motor. Background technique [0002] At present, wind power, as an environmentally friendly and economical energy source, has received extensive attention from researchers at home and abroad. [0003] With the continuous use of high-power level fans, the volume and quality of hardware equipment are getting larger and larger. Because wind turbine towers often use bulky mechanical gearboxes for speed increase, they bear heavy loads and are inconvenient to install and maintain. The hydraulic system is small in size, lightest in weight, good in dynamic response, large in torque, and mature in transmission mechanism technology. However, due to the low speed and large torque when the wind turbine is running, the traditional hydr...
