It is connected on during the long-term use of machinery and certain abrasion occurs, skidding can be produced when serious, although some are to pass through
Key enters line-locked, but so assembles cumbersome, effect is bad.
In addition, worm screw made of some plastics is during use, the side of the helical tooth on worm screw, particularly helical tooth
The phenomenon of fracture occurs in edge, and it is stuck to easily cause machine, influences to use.
Easily there is the phenomenon for loosening, skidding also due to the problem of connecting in worm gear, and using effect is poor.
Utility model content
Cumbersome in order to solve existing worm screw assembling, easily the problem of generation skidding, the utility model provides a kind of dress
With simple, the new type worm wheel worm gearing of service life length.
To achieve these goals, technical scheme provided by the utility model is：A kind of new type worm wheel worm gearing,
Including worm gear and worm screw, the worm gear and the worm engaging, the worm screw include worm shaft, and the centre of the worm shaft is provided with
Helical tooth, the both ends of the worm shaft are respectively equipped with the first installation portion and the second installation portion, first installation portion and described the
First through hole and the second through hole are offered on two installation portions respectively, the first through hole is provided with screw thread with second through hole；Institute
Stating helical tooth includes initiating terminal, pars intermedia and terminal, the helical tooth thickness at the terminal and initiating terminal be more than it is described in
Between portion's helical tooth thickness 2/5；The worm gear includes worm wheel body, and the worm wheel body periphery is provided with worm-gear toothing, the worm wheel body
Inner side is provided with through hole, and the through hole is into regular hexagon；The one side periphery of the through hole is provided with positive six side corresponding with the through hole
The projection of shape, the projection are provided with least one connecting hole.
As further technical scheme, the first groove of annular is provided with by first installation portion.
On the basis of such scheme, the second groove of annular is provided with by second installation portion.
As preferable technical scheme, the depth of first groove and the second groove is straight more than or equal to the worm shaft
Footpath 1/5 and less than the worm screw shaft diameter 1/3.
Further, the cross section of the groove is in the arc-shaped.
As preferable technical scheme, the quantity of the connecting hole is two, and using the center of through hole as symmetrical point symmetry
Set.
The utility model is relative to the beneficial effect of prior art：The worm screw is provided with by the both ends in worm shaft
The through hole of screw thread, inserted by screwed connecting rod in through hole to realize that worm screw and the fixed of power set connect during assembling
Connect, so worm screw and power set can firmly be linked together, and assemble simple；In addition, by by worm screw
Helical tooth thickness at terminal and initiating terminal is set greater than the 2/5 of pars intermedia helical tooth thickness, because thickness is big, so by force
Spend all right, such worm screw the phenomenon being broken would not occur during work, and can effectively improve worm screw uses the longevity
Life；Worm gear is attached output shaft using the through hole of hexagon, and such long-term use is not in because abrasion occurs what is skidded
Phenomenon, it is that setting through hole progress is longitudinally fixed furthermore with projection, effect is more preferable.
Brief description of the drawings
Fig. 1 is overall structure figure of the present utility model；
Fig. 2 is worm structure figure of the present utility model；
Fig. 3 is worm gear arrangement figure of the present utility model.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
As depicted in figs. 1 and 2, a kind of new type worm wheel worm gearing, including worm screw 1, and the worm gear being engaged with
2, the worm screw 1 includes worm shaft 101, and 101 sides of worm shaft are provided with helical tooth 102, and the both ends of worm shaft 101 are provided with the first peace
The installation portion 104 of dress portion 103 and second, two installation portions be all into it is hexagonal cylindric, for inserting power set, in order to more
Good fixation, has opened up screwed through hole 301 and 401 respectively on installation portion 103 and 104, in assembling, by with
In externally threaded connecting rod insertion through hole, it becomes possible to further worm screw and power set are fixed up, so can be by snail
Bar and power set firmly link together, and assemble simply, and assembling is firm, and the product effectively improved uses the longevity
Life.
In addition, there is the cross section Cheng Yuan of annular on the side of the first installation portion 103 and the side of the second installation portion 104
The depth of the groove 105 and 106 of arc, the groove 106 and groove 107 be more than or equal to the diameter of worm shaft 1 1/5 and it is small
In the 1/3 of the diameter of worm shaft 1, in the present embodiment, the depth of the groove is arranged to the 1/4 of worm screw shaft diameter.Groove 106 with
And groove 107 is used to be put into packing ring, can reduce friction during rotation, improve the service life of equipment.
Helical tooth 102 includes initiating terminal 121, pars intermedia 122 and terminal 123, in order to solve asking for the fracture of helical tooth 102
Helical tooth thickness at the terminal 123 of helical tooth and initiating terminal 121 is more than the pars intermedia helical tooth 122 by topic, the worm screw
The 2/5 of thickness, in the present embodiment, by the last lap helical tooth of terminal 123 and the last lap helical tooth of initiating terminal 123
Thickness be arranged to pars intermedia 122 helical tooth thickness 1/2, so because thickness is big, so intensity is all right, such worm screw exists
During work, the phenomenon being broken would not occur, can effectively improve the service life of worm screw.
As shown in figure 3, worm gear 2 includes worm wheel body 201, the periphery of worm wheel body 201 is provided with worm-gear toothing 202, worm wheel body 202 it is interior
Side is provided with through hole 203, and through hole 203 is into regular hexagon；The one side periphery of through hole 203 is provided with and 203 corresponding regular hexagon of through hole
Projection 204, raised 204 periphery be provided with using the center of through hole as symmetrical two connecting holes 205 of symmetric points, six sides
The through hole 203 of shape is attached output shaft, such long-term use be not in because there is the phenomenon skidded in abrasion, furthermore with
Through hole 205 is set in projection 204, further fixation, such fixed effect are done by the connector and output shaft of pin etc
More preferably, be not in sliding phenomenon during rotation, and process the use that simply, can effectively extend transmission device
Life-span.
