Description

A kind of wind turbine gearbox planetary structure
Technical field
The present invention relates to a kind of wind turbine gearbox planetary structures, belong to Planetary Gear Transmission technical field.
Background technology
Planetary Gear Transmission due to its bearing capacity is high, speed than it is big the advantages that, be widely used for wind turbine gearbox industry. Traditional wind-powered electricity generation planetary structure, planetary bearing are mainly cylinder roller bearing and taper roll bearing, are preparing bearing spacer Behind gap, positioning is fixed in one adjusting pad of match grinding again between planet carrier swing arm；There is tune for this wind-powered electricity generation planetary structure The measurement installation and dismounting of whole pad are extremely inconvenient, and the defects of can not ensure bearing clearance accuracy.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, a kind of simple in structure, reasonable design is provided, it can letter The wind turbine gearbox planetary structure of prompt quickly and effectively control bearing clearance.
The purpose of the present invention is what is completed by following technical solution, a kind of wind turbine gearbox planetary structure is main To include planet carrier, planet axis, bearing spacer, planetary gear, bearing, adjustment ring, bolt, circlip, the planet axis is loaded on On planet carrier, by bearing loaded in planet axis, adjustment ring is mounted on blending bolt on planet carrier and is attached fixation planetary gear； The flexible back-up ring mounting groove of adjustment ring endoporus, endoporus coordinate with planet axis, and are equipped with and planet axis is carried out axially Fixed circlip.
As preferred：The planet axis hole side setting of the planet carrier is wrapped on the step surface of stepped hole there are one stepped hole The bolt hole for fixing adjustment ring, the clearance for controlling bearing last by the small end face of match grinding adjustment ring are enclosed containing one.
Adjustment ring and planet carrier is bolted in the present invention, and positioning is fixed to planet axis with adjustment ring, avoids The problems such as adjustment ring is difficult to install, bearing clearance is inaccurate.
The present invention has simple in structure, reasonable design, the features such as measuring simple installation, can effectively control bearing clearance.
Description of the drawings
Fig. 1 is structure diagram of the present invention.
Specific embodiment
Below in conjunction with attached drawing, the present invention is further illustrated.Shown in Fig. 1, a kind of wind power gear of the present invention Case planetary structure mainly includes planet carrier 1, planet axis 2, bearing spacer 3, planetary gear 4, bearing 5, adjustment ring 6, bolt 7, elasticity Baffle ring 8；The planet axis 2 is loaded on planet carrier 1, and planetary gear 4 by bearing 5 loaded in planet axis 2, be expert at by the installation of adjustment ring 6 Blending bolt 7 is attached fixation in carrier 1；The flexible back-up ring mounting groove of 6 endoporus of adjustment ring, endoporus and planet axis 2 cooperations, and the circlip 8 that axial restraint is carried out to planet axis 2 is installed.
The planet axis hole side setting of the planet carrier 1 is used on the step surface of stepped hole comprising a circle there are one stepped hole In the bolt hole of fixed adjustment ring 6；The clearance for controlling bearing last by the small end face of match grinding adjustment ring.
After the bearing spacer 3 and planetary gear 4, bearing 5 are mounted between 1 swing arm of planet carrier together, planet carrier 1 is measured To 5 end face distance of bearing, 6 height of adjustment ring is matched to be milled to after the size through bolt 7 on planet carrier 1 rank.
The planet axis 2 is loaded in 1 axis hole of planet carrier, measures in adjustment ring 6 circlip mounting groove to 2 end face of planet axis 8 thickness of circlip is matched and is milled to after the size loaded in adjustment ring 6 by distance.
