Deep hole speed-up gear box

Abstract

The invention belongs to the field of mechanical engineering, and particularly relates to a deep hole speed-up gear box which comprises a high-speed rotating shaft, an output rotating shaft, a speed-up conversion assembly and an output end connector. The high-speed rotating shaft and the output rotating shaft are connected through the speed-up conversion assembly, a high-speed bearing supportsleeves the high-speed rotating shaft, and an output bearing support sleeves the output rotating shaft; a shell is arranged between the high-speed bearing support and the output bearing support, and one end of the output end connector is inserted into the other end of the output bearing support. According to the gear box, the problem that parts of the gear box are inconvenient to splice is solved; an operator can splice and fix the shell, the high-speed bearing support, the output bearing support and the output end connector conveniently through a splicing mechanism, so that the operation convenience is improved; the sealing performance between the parts is improved at the same time through the design of a sealing ring and a sealing sleeve, and a dust-proof effect is realized, so that the service life of the gear box is prolonged.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a deep-hole speed-increasing gearbox. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. The gearbox is an important mechanical component that is widely used in wind turbines. Its main function is to turn the wind wheel The power generated under the action of wind is transmitted to the generator and makes it obtain the corresponding speed. Usually the speed of the wind wheel is very low, far below the speed required by the generator to generate electricity, and must be realized through the speed-up effect of the gear pair of the gearbox. [0003] The deep-hole speed-increasing gearbox is a kind of gearbox, which is the reverse motion of the reduction gearbox. Its main feature is that the high-speed shaft is thick and the output shaft is small...
