Horizontal axis sea current energy generating set and its speed-up gearbox

Abstract

The invention discloses a speed-up gearbox of a horizontal-axis ocean current energy generator set. The speed-up gearbox of the horizontal-axis ocean current energy generator set comprises a gear ring, at least three primary shafts, a secondary shaft and a high-speed shaft, wherein the gear ring rotates synchronously with a main shaft, the primary shafts are evenly and annularly distributed with the axis of the main shaft as the center axis, and the secondary shaft and the high-speed shaft are both coaxial with the main shaft. Each primary shaft is parallel to the main shaft. One end of each primary shaft is provided with a primary shaft gear, and the other end of each primary shaft is sleeved with a transmission shaft which rotates synchronously with the primary shaft. Each transmission shaft is provided with a transmission gear synchronously rotating with the transmission shaft. The primary shaft gears are meshed with the gear ring, and an inner gearing transmission mechanism is formed. The two ends of the secondary shaft are provided with a secondary shaft gear and outer splines correspondingly. The secondary shaft gear is meshed with the transmission gears, and an outer gearing transmission structure is formed. The end face of the end, facing the secondary shaft, of the high-speed shaft is provided with a blind hole. Inner splines meshed with the outer splines are arranged in the blind hole. The high-speed shaft is sleeved with a brake disk rotating synchronously with the high-speed shaft. The high-speed shaft is provided with a coupler connected with an input shaft of a generator. The invention further discloses the horizontal-axis ocean current energy generator set.

Description

technical field

[0001] The invention relates to a generator set, in particular to a horizontal axis ocean current energy generator set and a speed-increasing box thereof. Background technique

[0002] Energy shortage is a common problem faced by all countries in the world today, and the development of renewable energy is urgent. In the field of renewable energy, ocean current energy is a kind of clean and renewable energy. my country has abundant ocean current energy reserves, and its development and utilization potential is huge. Ocean current energy has the advantages of high energy density and strong predictability. The horizontal axis ocean current energy generator is a device that converts ocean current energy into electrical energy. Most of the existing horizontal axis ocean current energy generators generate electricity in one direction. It is relatively easy technically, but many offshore terrains ebb and flow. To increase power generation, two-way power generation ...
