The shaft part of the present invention has characteristics of long service, large bearing capacity, and low maintenance cost.

Description

A kind of axial workpiece of helical trajectory linear contact lay surface
Technical field
The present invention relates to the technical field of axial workpiece, refer in particular to a kind of axial workpiece of helical trajectory linear contact lay surface.
Background technique
Bearing is widely used in All aspects of, and in such applications, bearing bears the contact force between the object that is connected, allows to be connected to rotate between object or the relative movement such as mobile simultaneously.In relative movement, wearing and tearing are inevitable, and this is that the frictional force produced in movement process between object is relevant, and frictional force more galling is more serious.Wearing and tearing comprise free particle and scratch, embed bearing surface, and along with the aggravation of wearing and tearing, friction increases, and wearing and tearing are just more and more serious.Existing technology is by providing a softer contact surface to allow most of particle to scratch or embed to be removed from the interface between surface by particle, thus the effect reduced wear.Also particle is allowed to concentrate the amounts of particles reduced between bearing surface away from bearing surface to reduce scuffing by introducing granule trap.Reduce wear by improving bearing surface degree of finish in the prior art.
Guiding device the most frequently used on guide pillar guide pin bushing mould and lathe is the strength member connecting upper and lower mould, and the guide pillar guide pin bushing adopted at present often adopts the interference fit of the Spielpassung of slide-and-guide or guiding of rolling.After long-term work, thermal expansion between guide pillar guide pin bushing makes wearing and tearing aggravate, and causes matching gap to increase, and guiding accuracy reduces, adding unbalanced lateral forces in guide pillar guide pin bushing working procedure will make upper and lower mould pressure center offset, and is difficult to ensure that guide pillar coordinates with the correct of guide pin bushing.Conventional guide pillar guide sleeve structure form is divided into sliding-type guide pillar guide pin bushing and roll type guide pillar guide pin bushing, sliding-type guide pillar guide pin bushing is face contact, guide pillar guide pin bushing is Spielpassung, and this can not meet requirement in the process of precision stamping, and in long-term working procedure serious wear; Roll type guide pillar guide pin bushing is then to eliminate gap, between guide pillar and guide pin bushing, be pressed into ball, makes the interference value keeping 0.01-0.02mm between three, therefore the guiding of upper and lower mould accurately, reliably, and frictional force reduces, but this will cause processing difficulties, and assembling is also difficult.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and defect, the axial workpiece on the helical trajectory linear contact lay surface that a kind of long service life, bearing capacity are large, maintaining cost is low is provided.
For achieving the above object, technological scheme provided by the present invention is: a kind of axial workpiece of helical trajectory linear contact lay surface, include axle and be fixed on the helical trajectory cylindrical member on this axle, wherein, described helical trajectory cylindrical member be wrapped in axle by silk ribbon material axle body on shaping along its axial screw, after shaping, the outer surface of this helical trajectory cylindrical member is the working surface of axle, and there is space between silk ribbon material between two, can hold lubricant oil and free particles.
The two ends of described axle are respectively equipped with a silk ribbon material mounting hole, and the silk ribbon head at described helical trajectory cylindrical member two ends penetrates in respective corresponding silk ribbon material mounting hole, and employing is weldingly fixed in hole.
Described helical trajectory cylindrical member is weldingly fixed on axle, and its silk ribbon material be around while welding.
Pasted fixing between the internal surface of described helical trajectory cylindrical member and the outer surface of axle by adhesive material.
Described adhesive material is silicon sealant.
Described silk ribbon material is made up of high-abrasive material, and its sectional shape is circular, square, rectangle or abnormity.
Described high-abrasive material has Cuprum alloy, stainless steel, alloyed steel, Bearing Steel, tool steel.
Compared with prior art, tool has the following advantages and beneficial effect in the present invention:
1, be linear contact lay between axial workpiece of the present invention and functional contact face, contact stress is little, and bearing capacity is larger;
2, silk ribbon material is soft, can be out of shape, have adaptivity during work along with the distortion of axle;
3, silk ribbon material is easy to stretching at ambient temperature, bends, easily tight winding shaping;
4, the silk ribbon material twister that the present invention is used can intercept from very long spiral winding thing, and manufacturing efficiency is high;
5, silk ribbon material obtains after being through drawing, the large plastic working of rolling, and mechanical property is high, wear-corrosion resistance good;
6, the space between silk ribbon material is little and comparatively even, and can hold lubricant oil and free particles, the degree of wear can greatly reduce.
7, after long-term work uses silk ribbon material to be worn, silk ribbon material is easy to change, and maintaining cost is low.
