Abstract

The invention discloses a constant-speed transmission device used for power generation of a wind turbine and a fuel engine. The constant-speed transmission device comprises a main differential mechanism, a deputy differential mechanism, a first turbine worm reducer with a self-locking function, a second turbine worm reducer without the self-locking function, and a driving gear and a driven feat which are meshed with each other, and a synchronous motor; by utilizing a differential speed adjustment principle of the differential mechanisms, a first sun gear of the main differential mechanism is connected with an engine revolving shaft under variable working conditions to form a driving wheel, and the rotation speed of a second sun gear is adjusted to achieve a constant planet carrier speed transmission by the self-locking function of the first turbine worm reducer, and the rotation speed of the self-locking turbine worm reducer is limited by the deputy differential mechanism and a second turbine worm reducer without the self-locking function, the rotation speed of the second sun gear and a fourth sun gear of the main and deputy differential mechanisms is changed along with the rotation speed of the engine due to the constant speed of the synchronous motor, and the output of the main differential mechanism is the same as the rotation speed of the synchronous motor so that an aim of constant speed transmission is achieved.

Description

technical field [0001] The invention relates to a constant-speed output transmission device, in particular to a transmission device for converting the variable-speed transmission output of a wind turbine or a fuel engine into a constant-speed transmission output. Background technique [0002] In recent years, with the worldwide emphasis on environmental protection and global warming, countries are competing to develop renewable energy utilization technologies, including wind energy, and wind energy is an option in energy policies for sustainable development. As one of the most important clean energy sources, wind energy has attracted more and more attention, and its share in the field of human energy utilization is increasing. The wind turbine is subject to the influence of the wind force, and the speed is a variable speed. After being directly connected to the generator, the output current, voltage, frequency [0003] Due to the increasing shortage of fossil energy and the...
