Abstract
The invention discloses a herringbone gear planet gear tooth telescopic assembly mechanism which comprises a planet gear, a rotary handle, a driving screw, a connector, a single gear tooth and a hexagonal hole table, wherein the gear tooth assembled with a gear tooth telescopic structure is manufactured independently, and an inverted trapezoidal groove is arranged on the bottom surface of the gear tooth and is connected with the connector of the inverted trapezoidal structure in a matched manner; a threaded hole is formed in the bottom of the joint, and the driving screw is connected with the joint through the threaded hole in the bottom of the joint; the driving screw is fixed with the hexagonal hole platform through welding through a hexagonal screw head at the other end; one end of the rotating rod is provided with a rotating handle, and the other end of the rotating rod is provided with a hexagonal hole platform, and the rotating handle and the hexagonal hole platform are welded into a whole. The driving screw is driven to rotate by rotating the rotary rod, so that the connector is pushed to move up and down along the radial direction, and finally the gear teeth stretch out and draw back along the radial direction.
Description
Technical Field
The invention relates to the technical field of planetary gear manufacturing, in particular to a herringbone gear planetary gear tooth telescopic assembling mechanism.
Background
In the field of planetary gear transmission, herringbone gear transmission is widely applied due to the transmission superiority, and herringbone gear planetary transmission has the advantages of planetary gear transmission and herringbone gear transmission, not only has the advantages of large overlap ratio, high bearing capacity and stable transmission of the herringbone gear transmission, but also has the advantage of power split of the planetary gear transmission. However, the herringbone-tooth planetary gear train is difficult to assemble, which is a great problem for restricting the development of the herringbone-tooth planetary transmission. At present, in order to reduce the assembly difficulty of the herringbone gear planetary gear train, a method for separately manufacturing the herringbone gear inner gear ring appears in the market, although the method reduces the assembly difficulty of the herringbone gear planetary gear train to a certain extent, the rigidity of the corresponding inner gear ring is greatly weakened, the assembly precision is reduced, and the service life of each gear in the herringbone gear planetary gear train is further reduced.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides the herringbone-tooth planetary gear tooth telescopic assembling mechanism, so that the problem of difficulty in assembling a herringbone-tooth planetary gear train is solved, the assembling difficulty is reduced, and the assembling efficiency is improved.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a herringbone gear planet gear tooth telescopic assembly mechanism which comprises a planet gear, a rotary handle, a hexagonal hole table, a driving screw and a joint. The gear teeth of the planet gear, which need to be stretched, are separately machined and manufactured, and the bottom surface of the gear teeth is provided with an inverted trapezoidal groove which is matched and connected with the joint; the joint is connected with the driving screw through a threaded hole at the bottom; the other end of the driving screw is provided with a hexagonal screw head; the hexagonal screw head is connected with a hexagonal hole at one end of a rotating rod, and the rotating rod is formed by welding a hexagonal hole table and a rotating handle into a whole; the rotary handle at the other end of the rotary rod is used as an operation part, and torque action can be exerted through the rotary handle.
As a preferable scheme of the invention, the gear teeth of the planet gears are stretched to the length from the meshing reference circle of the gear teeth to the addendum circle, the gear teeth are retracted along the radial direction before assembly, and the gear teeth are ejected after positioning so as to ensure correct meshing.
In a preferred embodiment of the present invention, the rotating rod is a whole, and the rotating handle is fixed to the hexagonal hole at the end of the rotating rod by welding.
Compared with the prior art, the herringbone-tooth planet wheel tooth telescopic assembly mechanism has the advantages that the interference problem in the planet wheel installation process is avoided by driving individual wheel teeth to retract along the radial direction, so that the herringbone-tooth planet wheel is more convenient to install, and the assembly time is saved; through the radial ejection of gear teeth, the assembly of the planet gear is finally realized, the problem that the herringbone gear planetary gear train is difficult to assemble is solved, and the assembly efficiency of the planetary gear train is improved.
