Assembly mold and assembly method of planetary gear

Abstract

The invention relates to the technical field of assembly of planetary gears, and discloses an assembly mold and an assembly method of a planetary gear. The assembly mold of the planetary gear comprises a base, wherein the base is provided with a rotating module, the rotating module comprises a rotating table and a locking structure, and the locking structure can lock a planet carrier on the rotating table; a measuring module which is located on one side of the rotating table and is configured to measure first position information of a pin shaft hole of the planet carrier and second position information of a notch of the planet carrier; a pushing module which is located on one side of the rotating table and is configured to push the planetary gear to the planet carrier from the notch according to the first position information and the second position information; and a lifting module which is located on one side of the rotating table and is configured to install the pin shaft in the pin shaft hole and the inner hole according to the first position information, so that the planetary gear is fixed to the planet carrier. According to the assembly mold of the planetary gear, rapid assembling of a gear box can be achieved, the service life of the gear box is prolonged, and the reliability of the gear box is improved.

Description

technical field [0001] The invention relates to the technical field of planetary gear assembly, in particular to a planetary gear assembly mold and an assembly method thereof. Background technique [0002] As a renewable energy source, wind power has strong advantages in power generation. Compared with thermal power, solar power and hydropower, wind power has the advantages of low construction cost, small footprint and convenient maintenance. As one of the key components of wind turbines, the gearbox is used to transfer the energy input by the blades and increase the speed at a lower speed to the motor for power generation. The gear is an important part of the gearbox. Take the planetary gear as an example. The function of the planetary gear is to transmit the speed and torque of the planetary carrier to the sun gear, which plays a vital role in the entire gearbox structure. [0003] In the gearbox, the planetary gears are mounted in the planetary carrier through bearings a...

Problems solved by technology

Due to the small volume between the planetary gear and the front and rear webs of the planetary carrier, and the requirement of axial clearance and radial clearance between the planetary gear and its corresponding support bearing, these requirements are currently achieved through manual assembly, limited by Due to the experience of assembly staff and the impact of fluctuations in working conditions, surface damage such as bumps often occurs during the assembly process of planetary gears and the entire planetary-level subassembly parts, which has a relatively large adverse effect on the load-carrying capacity of planetary gears and their bearings. The service life and reliability of the gearbox are greatly reduced
