Description

Double output hydroelectric planetary speed increaser

technical field

The invention relates to a planetary speed increaser, in particular to a planetary speed increaser with a double output structure for hydroelectric power generation.

Background technique

Existing speed-up gearboxes for hydroelectric power generation generally adopt parallel shaft gear speed-up transmission or NGW planetary gear speed-up transmission mechanisms. Parallel-shaft hardened gears are generally used for speed-up ratios less than 4, and NGW planetary gears are generally used for speed-up ratios greater than 4. Usually, the speed increaser has a single input and a single output. When the generator fails or is overhauled, it needs to be shut down, which will affect the normal power generation.

Contents of the invention

In order to solve the problem that the single-input and single-output structure of the hydroelectric power generation speed increaser in the prior art cannot meet the needs of continuous operation, the present invention provides a double-output hydropower generation planetary speed increaser, which has a compact structure, reliability, safety, and High efficiency and carrying capacity, can meet the single output or double output requirements of the speed increaser, has the advantages of no need to stop for maintenance, continuous operation and power generation.

The technical solution adopted in the present invention is: a double-output hydropower planetary speed increaser, including a casing, an input shaft, a planetary gear transmission mechanism and an output shaft, the input shaft is connected to the output shaft through the planetary gear transmission mechanism in the casing, and its characteristics A driving bevel gear is sleeved on the output shaft, a driven bevel gear meshes with the driving bevel gear, and the driven bevel gear is connected to another output shaft.

The output shaft includes a first internal tooth transmission shaft and a first output shaft, one end of the first internal tooth transmission shaft is connected to the planetary gear transmission mechanism, and the other end of the first internal tooth transmission shaft is internally connected through a first connection with a first shift fork. The gear sleeve is connected to the first output shaft, and the driving bevel gear is sleeved on the first internal gear transmission shaft.

The other output shaft includes a second internally toothed transmission shaft and a second output shaft, one end of the second internally toothed transmission shaft is connected to the driven bevel gear, and the other end of the second internally toothed transmission shaft is passed through a second fork with a second shift fork. Connect the inner gear sleeve to connect the second output shaft.

The driving bevel gear and the driven bevel gear are in a vertical meshing state.

After adopting the above technical scheme, the beneficial effects achieved by the present invention are: the low-speed stage of the speed increaser adopts a planetary gear transmission mechanism, the sun gear floats, the load capacity is large, the floating load is equal, the volume can be reduced, the weight can be reduced, and its structural reliability, High safety, efficiency, and load-carrying capacity; the driving bevel gear and the driven bevel gear are vertically meshed and play the role of reversing. One output or dual output can meet the requirements of dual output generators working at the same time. When any output generator fails, there is no need to stop for maintenance, and the other output generator can work normally without affecting the normal power generation operation; the bevel gear auxiliary speed ratio affects the speed increaser.

In the present invention, a bevel gear pair is added to the output shaft of the traditional speed increaser, and another output shaft is driven by the bevel gear pair to realize the second output of the speed increaser. The structure is compact, and the reliability, safety, efficiency and carrying capacity are high. It can meet the single output or dual output requirements of the speed increaser, without shutting down for maintenance, and can continue to operate and generate electricity.
