Abstract
Variable propeller gearbox of wind power generator needle roller designed by the utility model, including cylinder-shaped body, cylinder-shaped body end face is equipped with long round tube hole, the center line and cylinder-shaped body axis collinear of the long round tube hole, circular through hole, the tangential in the long side of the circular through hole axial cross section and the radial section of long round tube hole are additionally provided on the cylindrical surface of cylinder body.The characteristics of this structure is that lubricating oil can be entered inside needle roller by slotted hole and uniformly be flowed out in the gap of bearing, improve lubricant effect, wherein centrifugal effect can be improved in slotted hole, and angularly disposed circular through hole then can guarantee that the rate of outflow of lubricating oil is neither fast nor slow, to be effectively formed lubricating oil film.
Description
Technical field
The utility model belongs to a kind of needle roller, especially a kind of variable propeller gearbox of wind power generator needle roller.
Background technique
Needle bearing is the roller bearing with cylindrical roller, when the work of the Internal and external cycle of needle bearing, drives needle roller high speed
Rotation, lubricating criteria require very high.Gap is small between existing needle roller and contact surface, and lubricating oil is difficult to enter.
Utility model content
To solve the above problems, the utility model, which provides a kind of lubricating oil, is easily accessible contact surface gap, and can be uniformly
Release, guarantees the variable propeller gearbox of wind power generator needle roller of lubricant effect.
In order to achieve the above object, variable propeller gearbox of wind power generator needle roller designed by the utility model, including cylinder
Shape main body, cylinder-shaped body end face are equipped with long round tube hole, and the center line and cylinder-shaped body axis of the long round tube hole are total
Line, is additionally provided with circular through hole on the cylindrical surface of cylinder body, and the long side of the circular through hole axial cross section is led to oval
Tangential on the radial section in hole.It is inside needle roller and equal that the characteristics of this structure, is that lubricating oil can be entered by slotted hole
In the even gap for flowing out to bearing, lubricant effect is improved, wherein slotted hole can be improved centrifugal effect, and angularly disposed circle
Shape through-hole then can guarantee that the rate of outflow of lubricating oil is neither fast nor slow, to be effectively formed lubricating oil film.
Further embodiment is that the two sides of cylinder-shaped body are symmetrically arranged in multiple circular through holes.By right
The circular through hole for claiming setting, can guarantee the stable rotation of needle roller, reduces unnecessary friction.
Further scheme is axis of multiple circular through holes in cylinder-shaped body that cylinder-shaped body side is arranged in
It is upper uniformly distributed, and aforementioned adjacent any its angle of a pair of of circular through hole on the axis of cylinder-shaped body is opposite.By symmetrically setting
That sets and be spaced is oppositely arranged, can guarantee in the case where bearing positive and negative rotation, can uniform fuel feeding.
Compared with prior art, variable propeller gearbox of wind power generator needle roller designed by the utility model, passes through slotted hole
Uniform release lubricating oil is designed using structure in the case where guaranteeing oil inlet quantity with the setting of angularly disposed circular through hole,
To guarantee the lubricant effect of bearing.
Detailed description of the invention
Fig. 1 is 1 axial sectional view of embodiment.
Fig. 2 is 1 radial cross-section of embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Embodiment 1.
As shown in Figs. 1-2, the variable propeller gearbox of wind power generator needle roller of the present embodiment description, including cylinder-shaped body 1, circle
1 end face of cylindrical bodies is equipped with long round tube hole 2, the center line of the long round tube hole 2 and 1 axis collinear of cylinder-shaped body,
Circular through hole 3, the long side of 3 axial cross section of circular through hole and long round tube hole 2 are additionally provided on the cylindrical surface of cylinder body
Radial section on tangential.The two sides of cylinder-shaped body 1 are symmetrically arranged in circular through hole 3.Setting is main in cylinder
Multiple circular through holes 3 of 1 side of body are uniformly distributed on the axis of cylinder-shaped body 1, and the aforementioned phase on the axis of cylinder-shaped body 1
Adjacent any its angle of a pair of of circular through hole 3 is opposite.
Claims (3)
