Abstract

The invention relates to a vertical-axis wind power speed increasing transmission device, which comprises a base I, a big gear ring, an open small gear, a box body, a speed increasing machine, a generator, a safety coupling, a gasket set, a gear coupling, a platform and a base II, wherein the base I is installed on the basis, the box body is installed on the base I, the open small gear is installed on the box body, the platform is located above the base I, the base II is installed on the platform, the speed increasing machine is installed on the base II, an input axis of the speed increasing machine is connected with the open small gear through the gear coupling, and the safety coupling is installed between the open small gear and the gear coupling. The vertical-axis wind power speed increasing transmission device has the beneficial effects that the height from a meshing force action line to the ground is shortened, and the overturning moment is reduced; the speed increasing machine is more reasonable in stress state, the service life of the speed increasing machine is prolonged, and the basis stress of the base I is reduced; gear coupling connection is convenient for maintenance, and radial deflection of a spindle head of the small gear can be compensated; and the safety coupling is independently installed between the small gear and the speed increasing machine, thereby enabling the safety coupling not to be directly affected by the meshing force of the small gear.

Description

Technical field [0001] The invention relates to a wind power increasing speed transmission device, in particular to a vertical axis wind power increasing speed transmission device. Background technique [0002] Vertical axis wind power generation is a device that converts wind energy into electrical energy. Its working principle is to use wind energy to drive the main shaft to rotate through the sail. The large ring gear on the main shaft drives multiple pinion gears to rotate. The pinion gear is increased by a speed increaser to reduce the speed. Increase the speed to meet the requirements of the generator, and finally the generator outputs electrical energy. The speed increasing transmission device is the core equipment of vertical axis wind power generation. Its function is to increase the speed of the main shaft to meet the requirements of the generator. The speed increasing transmission device of the prior art is usually assembled by a large ring gear and a pinion shaft. Th...

AI Technical Summary

Problems solved by technology

The large ring gear and pinion gear of the speed increasing device are installed above the speed increasing gear, and the meshing force action line is far away from the ground, resulting in a large overturning moment generated by the meshing force on the ground, which the foundation cannot bear

[0004] 2. The force situation of the speed increaser is complicated

[0005] 3. It is inconvenient to adjust the meshing accuracy of the open gear pair and is easily affected by the speed increaser

The existing technical solution is to install the pinion directly on the input shaft of the speed increaser. There are two problems in this way: one is that it is very inconvenient to adjust the meshing precision of the large ring gear and the pinion, and the gear of the speed increaser needs to be adjusted. The whole box, and the second is that the pinion is easily affected by the force and deformation of the speed increaser.

[0006] 4. The safety coupling is installed inside the pinion, which is easily affected by the meshing force of the open gear pair
