Abstract

The invention relates to a planetary transmission structure of a wind power gear box, which comprises a sun gear, a planetary bracket, a mandrel, planetary gear bearings, planetary bracket bearings and a planetary gear. The planetary bracket is mounted on a box through the planetary bracket bearings, the planetary gear is mounted on the mandrel through the planetary gear bearings, and the planetary gear bearings are a pair of tapered roller bearings and are mounted back to back. The planetary transmission structure is capable of bearing bending moment generated by axial force of the planetary gear more effectively, load impact from paddles is prevented, running reliability of the gear box is improved, and the working requirement of the wind power gear box is met.

Description

The Gear Planet Transmission structure of wind-powered electricity generation gear-box
Technical field
The present invention relates to a kind of Gear Planet Transmission structure, especially a kind of Gear Planet Transmission structure of wind-powered electricity generation gear-box.
Background technique
Therefore epicyclic transmission mechanism is because its velocity ratio is big, and stable drive and driving torque are big, through being usually used in the middle of the mechanism driving.Common planet carrier structure form has double-walled integrated type, double-walled split and single wall formula.Double-walled integral planet carrier good rigidly; Double-walled split planet carrier is mainly used in the less situation of velocity ratio than the integral planet carrier complex structure.Single wall formula planet carrier structure is simple, can hold more planet wheel.The planet wheel of epicyclic transmission mechanism is made the gear of hollow more, so that at endoporus assembling planet wheel shaft or bearing.
What the wind power system gear-box adopted is exactly epicyclic transmission mechanism, and its planet wheel is a hollow, and inside is equipped with mandrel and bearing.Because the outer blade of Gear Planet Transmission structure and wind-powered electricity generation gear-box links to each other, and that blade receives axial force is bigger, is directly delivered in the Gear Planet Transmission structure.Because what existing Gear Planet Transmission structure adopted is a pair of roller bearing, this structure only can bearing radial force, can not bear axial force, therefore causes reliability of operation to reduce.In addition, the support of existing planetary pinion drive mechanism is an one, and planetary assembling and dismounting and repairing be inconvenience very.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively bear the axial force that blade in the wind power system transmits, prevent the load impacting that paddle is brought, improve reliability of operation, the Gear Planet Transmission structure of the wind-powered electricity generation gear-box of being convenient to simultaneously to assemble and dismantle and repair.
Technological scheme of the present invention is: a kind of Gear Planet Transmission structure of wind-powered electricity generation gear-box; It is characterized in that; The Gear Planet Transmission structure of wind-powered electricity generation gear-box comprises sun gear, planet stent, axle, planet wheel bearing, planet stent bearing and planet wheel; On casing, planet wheel is installed on the axle through planet wheel bearing planet stent through the planet stent Bearing Installation, and described planet wheel bearing is a pair of taper roller bearing and back-to-back installation; Be provided with ring washer in the middle of the interior ring of taper roller bearing; In the middle of the outer shroud is convexity inside on the planet wheel, and the interior ring of a side of described a pair of taper roller bearing abuts against on the step that is provided with on the axle, and the interior ring of opposite side leans against through on the packing ring that is arranged on the screw location on the planet carrier.Described planet stent is for dividing body structure, and described planet stent bearing is the roller bearing of band rib.
The Gear Planet Transmission structure of wind-powered electricity generation gear-box comprises sun gear, planet stent, axle, planet wheel bearing, planet stent bearing and planet wheel; Planet stent passes through the planet stent Bearing Installation on casing; Described planet stent bearing is the roller bearing of band rib; Planet wheel is installed on the axle through planet wheel bearing, and described planet wheel bearing is a pair of taper roller bearing and back-to-back installation, is provided with ring washer in the middle of the interior ring of described a pair of taper roller bearing; In the middle of the outer shroud is convexity inside on the planet wheel; The interior ring of one side of described a pair of taper roller bearing abuts against on the step that is provided with on the axle, and the interior ring of opposite side leans against through on the packing ring that is arranged on the screw location on the planet carrier, and described planet stent is for dividing body structure.
The present invention has adopted a pair of taper roller bearing and back-to-back installation; Can bear the moment of flexure that the axial power of planetary pinion is produced better; Prevent the load impacting that blade brings, improve the operational reliability of gear-box, simultaneously; Planet stent can be so that the assembling of Gear Planet Transmission structure and dismounting and repairing for dividing body structure; The planet stent bearing is the roller bearing of band rib, can be through the axial internal clearance of spacer adjustment planet stent bearing; The interior ring of one side of taper roller bearing leans against through on the packing ring that is arranged on the screw location on the planet carrier, can eliminate the axial internal clearance of taper roller bearing through the adjustment screw.The present invention has simple in structure, and reliable advantage satisfies the job requirement of wind-powered electricity generation gear-box.
