Adopt said structure because with adopting bolt axis between flange plate and the planet carrier to ways of connecting, therefore under the situation of same bearer ability, can with the axial dimension of input flange do littler, and easy for installation.
For reducing the diameter of a circle that distributes, the joint of said joint and said input planet carrier is uniformly distributed with and is provided with the said bolt of two circles.
Preferable, the quantity of outer ring bolt and inner ring bolt equates; For improving the installing space of bolt, at said input flange radially, said outer ring bolt and inner ring bolt shift to install.
For improving bearing capacity, in each outer ring bolt connecting hole of said joint and said input planet carrier joint, interference fit has hollow pin; Arbitrary hollow pin all has part that is arranged in the said joint and the part that is arranged in the said input planet carrier; Each outer ring bolt passes corresponding hollow pin makes said joint be connected with said input planet carrier.
Preferable, said hollow pin is the open circles pin.
For alleviating the weight of input flange, the said relatively flange part of said joint is protruding to be provided with, and a side of this convex portion contacts with said planet carrier.
For preventing that bolt from withdrawing from, improve the reliability of linkage structure, be connected with cover plate through screw on the said input flange; Said cover plate is provided with the plane of limiting each said bolt axial motion.
For ease of being connected of input flange and output flange, the corresponding said joint of said input flange place is provided with counterbore; Said cover plate is arranged in the said counterbore; The exterior edge face of said screw head does not exceed second faying surface of said input flange and output flange applying.
Preferable, the head of said screw sinks in the said cover plate.
For ease of the faying surface of processing input flange and output flange, said input flange is provided with the circular pit of diameter greater than said counterbore.
The invention has the beneficial effects as follows:
Input flange is convenient to remove when (1) keeping in repair in the cabin, has effectively reduced the cabin design space.
(2) the open circles pin has not only improved the reliability that input is connected with being used of bolt, and has reduced the Conncetion cimension of traditional split pattern greatly, alleviates complete machine weight.
(3) use of cover plate has promptly effectively prevented the risk that withdraws from of bolt, the outward appearance of also having beautified complete machine.
In a word, compact structure of the present invention, bearing capacity is big, reliability is high, overall weight is light, installs simple and convenient.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Embodiment 1: as shown in Figures 2 and 3, a kind of wind-powered electricity generation gear-box input linkage structure comprises input flange 1 and input planet carrier 6, and input flange 1 comprises the flange part 1a and the joint 1b that is connected with input planet carrier 6 of one.
First faying surface 11 that joint 1b is provided with location outer stopper 12 and fits with the end face 10 of input planet carrier 6, input planet carrier 6 is provided with location inner stopper 13.Location outer stopper 12 and location inner stopper 13 Spielpassung.
In the present embodiment, the joint of joint 1b and input planet carrier 6 is uniformly distributed with and is provided with outer ring bolt 8 and inner ring bolt 4, and the quantity of outer ring bolt 8 and inner ring bolt 4 equates, is 24.At input flange 1 radially, outer ring bolt 8 shifts to install with inner ring bolt 4.Joint 1b is fixedly connected with inner ring bolt 4 through outer ring bolt 8 with input planet carrier 6.
In the present embodiment, outer ring bolt 8 and inner ring bolt 4 all adopt the hardness of the plain washer 5 that defined 10.9 grades of hexagon head bolts of standard GB/T5782 and inner ring bolt 4 be used should satisfy the HV300 grade among the GB/T97.1; The hardness of the plain cushion 7 that is used with outer ring bolt 8 should satisfy the HV300 grade among the GB/T97.1.
In other embodiments, according to the difference of transmitting torque, the bolt of other quantity can be set also, the concrete quantity of bolt can be calculated according to routine and obtain.Simultaneously, the bolt of other number of turns can be set also, like 1 circle, 3 circles or 4 circles etc., to reach essentially identical technique effect.
In the present embodiment, in each outer ring bolt connecting hole of joint 1b and input planet carrier 6 joints, interference fit has hollow pin 9.Arbitrary hollow pin 9 all has part that is arranged in the joint 1b and the part that is arranged in the input planet carrier 6, and each outer ring bolt 8 passes corresponding hollow pin 9 makes joint 1b be connected with input planet carrier 6.Hollow pin 9 adopts the 42CrMoA alloyed steel, and hardness can be selected 310～350HB for use, thereby makes hollow pin have very high anti-shear ability, has good impact toughness again.
In other embodiments, according to the needs of transmitting torque, also can be only or in the attachment hole of inner ring bolt, hollow pin is set simultaneously, to reach essentially identical technique effect.
In the present embodiment, hollow pin 9 is the open circles pin.In other embodiments, also can be set to resilient key, to reach essentially identical technique effect.
In the present embodiment, the relative flange part 1a of joint 1b is protruding to be provided with, and a side of this convex portion contacts with said planet carrier 6.The volume of whole input flange 1 is reduced.
Be fixedly connected with cover plate 3 through screw 2 on the input flange 1, the head of screw 2 sinks in the cover plate 3.Cover plate 3 is provided with first plane 14 and second plane 16 of limiting each outer ring bolt 8 axial motion of limiting each inner ring bolt 4 axial motion.Therefore can prevent that effectively inner ring bolt 4 and outer ring bolt 8 from withdrawing from tapped hole, thereby improve the reliability of linkage structure through the gap between adjustment cover plate 3 and inner ring bolt 4 and the outer ring bolt.
Because second faying surface 18 of input flange 1 needs fine finishing, for reducing the area of second faying surface 18, input flange 1 is provided with the circular pit 19 of diameter greater than counterbore 15, thereby makes the processing of input flange 1 more convenient, and cost is lower.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technician in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technological scheme of logical analysis, reasoning, or a limited experiment.
