Description
Technical field
The utility model is related to worm screw technical fields, are a kind of self-lubricating worm screw specifically.
Background technology
Worm screw is that only have one or several helical tooths, and engage and form the gear of gear pair with non-parallel with worm gear.
The advantages of worm-drive, is that transmission ratio is big, compact-sized, and stable drive is noiseless.Worm screw includes interconnecting piece and driving section, is connected
Socket part is used to coordinate installation to fix with other parts, and movement is transmitted in driving section for being engaged with worm gear.In transmission process worm screw with
Engagement between turbine generates axial force to worm screw, when bear load it is larger when, field of conjugate action frictional force is larger.
Currently, the lubrication of the wrom tooth field of conjugate action of worm screw mainly leans on oil pump toward oil jet lubrication at friction, this ecto-entad
Lubrication it is not comprehensive enough, wrom tooth bottom non lubricant oil may be caused.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of self-lubricating worm screw, lubricating oil is from wrom tooth bottom toward top
Diffusion.
In order to solve the above technical problems, the utility model provides a kind of self-lubricating worm screw, including：Main body and it is set to it
On multiple wrom tooths, axis of the body is provided with the first hole of a perforation, is arranged between the adjacent wrom tooth of each two
There are at least one second hole, second hole to be connected to first hole.
Further, the tie point of second hole and first hole is described away from the axial line distance of the main body
0.6~0.85 times of the radius of main body described in second hole corresponding position.
Further, the tie point of second hole and first hole is described away from the axial line distance of the main body
0.75 times of the radius of main body described in second hole corresponding position.
Further, second hole is cylinder, and axis is located at the radial direction of the main body.
Further, the radius of the cross section of second hole is 0.3~0.5mm.
Further, the radius of the cross section of second hole is 0.4mm.
Further, first hole is prismatic shapes.
Further, the cross-sectional shape of first hole is circle.
Self-lubricating worm screw provided by the utility model, lubricating oil is entered by the first hole in main body, by the second hole
The bottom between two wrom tooths is flowed out to, flow to the wrom tooth field of conjugate action under the influence of centrifugal force, realizes lubricating oil by wrom tooth bottom
Toward the purpose of top diffusion.

Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
A kind of self-lubricating worm screw, as shown in Fig. 1~5, including：Main body 1 and the multiple wrom tooths 2 being arranged on, main body 1 are
The axis of worm gear is cylindrical in the present embodiment, and under normal circumstances, the shape of main body 1 is rotary structure.In the main body 1
It is axially provided with the first hole 3 of a perforation, can be noted into lubricating oil at the both ends of main body 1 in this way, wrom tooth 2 described in each two
Between be provided at least one second hole 4, one is arranged in the present embodiment, second hole 4 connects with first hole 3
It is logical.
In one optional embodiment of the present embodiment, as shown in figure 5, the company of second hole 4 and first hole 3
Axial line distance B of the contact away from the main body 1 be 4 corresponding position of the second hole described in main body 1 radius C 0.6~
0.85 times.Bias design, convenient in 1 rotary course of main body by centrifugal force by lubricating oil from the second hole 4 and the first hole 3
It is thrown away outward at tie point.Preferably, axis of the tie point away from the main body 1 of second hole 4 and first hole 3
Distance is 0.75 times of the radius of main body 1 described in 4 corresponding position of the second hole.
In one optional embodiment of the present embodiment, second hole 4 is cylinder, and axis is located at the main body 1
Radial direction.Length is most short, is thrown away convenient for lubricating oil.
In one optional embodiment of the present embodiment, the radius of the cross section of second hole 4 is 0.3~0.5mm.It is excellent
The radius of selection of land, the cross section of second hole 4 is 0.4mm.
In one optional embodiment of the present embodiment, first hole 3 is prismatic shapes.
In one optional embodiment of the present embodiment, the cross-sectional shape of first hole 3 is round or as shown in Figure 3
Shape.Round manufacture easy to process, shape shown in Fig. 3 can ensure the intensity of main body 1.
The protection scope of the utility model is not limited thereto.Those skilled in the art are in the utility model on the basis of institute
The equivalent substitute of work or transformation, both are within the protection scope of the present invention.The scope of protection of the utility model is wanted with right
It asks subject to book.
