Abstract

The invention belongs to the field of mechanical transmission, and relates to a step-up gear box, in particular to a step-up gear box for wind power generation. A connecting flange of the step-up gear box is in interference with a front half section of a planetary carrier through a spline; cylindrical matching faces are in interference connection with each other to transmit loads; the cylindrical faces are in interference connection with each other, so that a spline pair is not influenced by a bending moment, and only a torque is transmitted; the spline pair adopts the interference connection, so that the problem that adverse factors such as opposite friction among keys and teeth influence the service life of the spline is solved during power transmission; a planetary gear train adopts a composite planetary gear train, so that the weight of the gear box is reduced, the quantity of bearings is reduced, and the processing and manufacturing costs of the gear box are lowered; the quantity of gear meshing pairs is reduced; and the transmission efficiency of the gear box is improved greatly.

Description

technical field [0001] The invention relates to a speed-up gearbox, in particular to a speed-up gearbox for wind power generation, which belongs to the field of mechanical transmission. Background technique [0002] With the increasing economic development, energy and environmental problems are becoming more and more serious. In particular, energy issues have become the focus of attention; among them, the development and utilization of renewable energy is the top priority of energy issues. As a kind of renewable energy, the competition for the development and utilization of wind energy has reached a fever pitch. As an essential part of wind power generation, speed-up gearboxes are constantly increasing. At present, the gearbox commonly used in wind power generation equipment adopts two-stage NGW planetary transmission and one-stage parallel shaft transmission, which have the disadvantages of heavy weight of the gearbox, large number of bearings, high manufacturing cost of ...
