It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combine.
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, the toggle of wind turbine gearbox of the present invention and pin shaft connection structure 10 are arranged in wind turbine gearbox 1
On, the toggle of wind turbine gearbox and pin shaft connection structure 10 are specifically arranged in the gear case body 20 of wind turbine gearbox 1
On, the toggle and pin shaft connection structure 10 of wind turbine gearbox are used to wind turbine gearbox 1 being installed to rack.Wind turbine gearbox
Toggle and pin shaft connection structure 10 toggle 11 at least two, toggle 11 is two in embodiment shown in FIG. 1,
Two toggles 11 are distributed in the two sides of 20 end of gear case body.It is understood that the number of toggle 11 can basis
It needs specifically to be arranged, is not limited to two, or three or four etc..Pin shaft 12 is threaded through the pin shaft on toggle 11
Pin shaft 12 is connected in rack by Kong Zhong, and wind turbine gearbox 1 can be installed in rack.
Bearing is necessarily provided on the transmission chain of wind turbine gearbox 1, and bearing can have end-play, when on transmission chain
When base bearing end-play is excessive or fails, wind turbine gearbox 1 will receive the effect of axial force, and it is axial to be easy to happen pin shaft 12
Play seriously threatens the reliability and safety of wind turbine gearbox 1.In the prior art, although pin shaft 12 is with toggle 11
Elastic conjunction, but also it is difficult to the problem of entirely preventing 12 axial motion of pin shaft.
As shown in Fig. 2, being avoided in the present invention using the method for fastener 13 is arranged between pin shaft 12 and toggle 11
Axial motion occurs for pin shaft 12.Fastener 13 is set on pin shaft 12, and fastener 13 is arranged in the pin shaft hole of toggle 11,
Fastener 13 and pin shaft 12 and fastener 13 and the equal elastic conjunction of toggle 11, thus than in the prior art directly by pin shaft 12
With toggle 11 assembly increase an interference fit face, at double increase pretightning force, can effectively prevent 12 axis of pin shaft
To vibration.
In one embodiment, fastener 13 is axle sleeve, as shown in Fig. 2, axle sleeve is set on pin shaft 12, pin shaft 12 is logical
Axle sleeve is crossed to be mounted in the pin shaft hole of toggle 11.It is axiomatic that the internal diameter of axle sleeve is not more than the diameter of pin shaft 12, in this way
The inner surface of pin shaft 12 and axle sleeve can just be interference fitted.The outer diameter of axle sleeve is not less than the diameter in 11 upper pin hole of toggle, this
Sample can just be such that the outer surface of axle sleeve and pin shaft hole is interference fitted.
As one embodiment of axle sleeve, as shown in Fig. 2, the inner wall 131 and outer wall 132 of axle sleeve are cylinder.Inner wall 131
The cooperation of cooperation and outer wall 132 and pin shaft hole with pin shaft 12 forms two interference fit faces, realizes big preload, promotes knot
The frictional force in conjunction face prevents 12 axial motion of pin shaft.
As another embodiment of axle sleeve, as shown in figure 3, the inner wall 131 of axle sleeve is cylinder, the outer wall 132 of axle sleeve is
The inner wall of the conical surface, the pin shaft hole of toggle 11 is the conical surface being adapted to the conical surface of the outer wall 132 of axle sleeve, and the cooperation of the conical surface can be more preferable
Prevent 12 vibration of pin shaft.In one embodiment, the gradient of the conical surface of axle sleeve outer wall 132 can be 1 °~10 °, 1 °~
10 ° of taper is not too large, and the difference in thickness that not will lead to axle sleeve wall surface is too big, influences the service life of axle sleeve.
For the ease of positioning of the axle sleeve in assembly, positive stop lug boss 133 can be set in one end of axle sleeve.It is shown in Fig. 2
Embodiment in, positive stop lug boss 133 may be provided at any end of axle sleeve.And in the embodiment shown in fig. 3, limit convex
The big end of axle sleeve, that is, the biggish one end of axle sleeve outer diameter is arranged in platform 133, because being that axle sleeve outer diameter is lesser when assembly
Pin shaft hole is protruded into assemble in one end, if the setting of positive stop lug boss 133 can be blocked in the lesser one end of axle sleeve outer diameter in assembly,
Cause axle sleeve that can not protrude into pin shaft hole, is unable to complete assembly.
It is also higher to the rigid requirements of components since the operation intensity of wind turbine gearbox 1 is higher, so axle sleeve needs are resistance to
Mill, in one embodiment, axle sleeve are steel shaft set, that is to say, that axle sleeve is manufactured using steel, is increased its wearability, is used the longevity
Life is longer, can also reduce the abrasion of the pin shaft 12 of toggle 11.
It is noted that further increasing axle sleeve and pin shaft 12, torsion to enhance the coefficient of friction of axle sleeve contact surface
Arm 11 assemble after frictional force, promoting total prevents the effect of 12 axial motion of pin shaft, can axle sleeve inner wall 131 and/
Or non-slip texture layer is set on outer wall 132, the protection lines of non-slip texture layer can be the non-slip texture of any shape, or
Anti-skidding salient point.In addition, non-slip texture layer can be positioned only on the inner wall 131 of axle sleeve or be positioned only at the outer wall 132 of axle sleeve
On, it can also be arranged in simultaneously on the inner wall 131 and outer wall 132 of axle sleeve.
In general, pin shaft 12 is elastic pin shaft, that is to say, that the surface of pin shaft 12 is coated with elastomeric layer, elastic material
Such as plastic cement.Pin shaft 12 is that elastic pin shaft can make the surface of pin shaft 12 have elasticity, is more advantageous to the elastic conjunction of pin shaft 12.
Preferably, as shown in Figure 1, toggle 11 is from the edge of 20 end of gear case body along the radial direction of gear case body 20
Extend, toggle 11 and gear case body 20 are integrally formed, and can promote the intensity of toggle 11 in this way.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and being not is pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, be able to carry out it is various it is apparent variation,
It readjusts and substitutes without departing from protection scope of the present invention.There is no need and unable to give thoroughly all embodiments
It lifts.Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the present invention
Within scope of protection of the claims.
