Description
Technical field
The utility model relates to a kind of flat position axle, the flat position of especially a kind of annular knurl axle.
Background technique
Minisize axial is the axial workpiece relatively little, precision is high, and Minisize axial can be described as again accurate axle, little axle, axle core, rotor shaft, pin, rivet, guide rod etc.The main material of Minisize axial is carbon steel, stainless steel, copper, aluminium of each material etc., and that surface treatment mainly contains is zinc-plated, nickel, blackout, carburizing etc.According to the carrying situation of Minisize axial, Minisize axial can be divided into again: 1, rotating shaft, during work, not only bear moment of flexure but also bear moment of torsion, and be modal axle in machinery, as axle in various retarders etc.2, axle, is used for supporting that rotational parts only bears moment of flexure and transmitting torque not, and some axle is rotated, and as the axle of railway vehicle etc., some axle is not rotated, as the axle of supporting pulley etc.3, transmission shaft, is mainly used to transmitting torque and does not bear moment of flexure, as the long optical axis in crane movable mechanism, the live axle of automobile etc.The material of axle mainly adopts carbon steel or alloyed steel, also can adopt spheroidal graphite cast iron or alloy cast iron etc.The ability to work of axle generally depends on strength and stiffness, also depends on stability of vibration when rotating speed is high.
And existing flat position axle belongs to a kind of of Minisize axial, when this flat position axle and foreign object assembling, cannot accurately be connected with the assembly department of foreign object, make efficiency of assembling lower; And lubricated mainly the relying on axle during work offered oil groove, stores lubricant oil and realizes, and still, the mode lubrication effect of this Sump lubrication is not very desirable, and the lubricant oil on the axle of flat position is easy to run off.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of assembling and the flat position of the difficult annular knurl running off of lubricant oil axle be convenient to.
The technical solution of the utility model is achieved in that the flat position of a kind of annular knurl axle, comprise cylindrical axle body, it is characterized in that: the front end edge of described axle body is radially provided with guiding breach, the bottom surface of this guiding breach is plane, and the front end of axle body is provided with cylindrical guide portion, and the guiding bottom surface of breach and the outer wall of guide portion are tangent, in the back end outer surface of described axle body, be provided with for holding some strip grooves of oil some strip grooves outer wall with axle body that distributes in the form of a ring.
By adopting technique scheme, guide portion can play leading role to flat position axle when assembling, can accurately be connected with the assembly department of foreign object, improve efficiency of assembling, and in the rear end of axle body, strip groove has been set, increased the area of contact with lubricant oil, lubricant oil can be adsorbed in this area of contact, effectively the unnecessary lubricant oil of flat position axle outer wall is held to oil processing, prevented the loss of lubricant oil, guaranteed lubrication effect.
The utility model is further set to: described strip groove comprises convergence part and hold oily portion, and the opening of convergence part is increased to the back-end gradually by the front end of axle body, and the joint of holding the ear end face of oily portion and axle body is plane.
By adopting technique scheme, it is large that convergence part becomes gradually, the mobile effect of playing acceleration that can be to lubricant oil, when lubricant oil enters relatively large space in less space, can produce the internal force of pullling between lubricant oil, be convenient to flowing of lubricant oil, hold oily portion and can hold oil processing to lubricant oil, and the joint of holding the ear end face of oily portion and axle body is plane, guaranteed that lubricant oil is difficult for running off, topology layout is more reasonable, for follow-up fuel feeding provides basis.
The utility model is also further set to: the stepped structure in the back side of described guide portion and guiding breach; The degree of depth of described guiding breach is less than or equal to the radius of axle body.
By adopting technique scheme, step structure is when assembling, the manual contact position of the flat position of perception axle and foreign object, further improved efficiency of assembling, and the degree of depth of guiding breach is less than or equal to the radius of axle body, when having improved efficiency of assembling, guaranteed the join strength of guide portion and axle body.
Accompanying drawing explanation
Fig. 1 is structural representation in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, the utility model discloses the flat position of a kind of annular knurl axle, comprise cylindrical axle body 1, in the utility model specific embodiment, the front end edge of described axle body 1 is radially provided with guiding breach 11, the bottom surface 111 of this guiding breach is plane, and the front end of axle body 1 is provided with cylindrical guide portion 2, and the bottom surface 111 of guiding breach is tangent with the outer wall of guide portion 2, in the back end outer surface of described axle body 1, be provided with for holding some strip grooves 12 of oil, some strip grooves 12 distribute and the outer wall of axle body 1 in the form of a ring.
By adopting technique scheme, guide portion can play leading role to flat position axle when assembling, can accurately be connected with the assembly department of foreign object, improve efficiency of assembling, and in the rear end of axle body, strip groove has been set, increased the area of contact with lubricant oil, lubricant oil can be adsorbed in this area of contact, effectively the unnecessary lubricant oil of flat position axle outer wall is held to oil processing, prevented the loss of lubricant oil, guaranteed lubrication effect.
In the utility model specific embodiment, described strip groove 12 comprises convergence part 121 and holds oily portion 122, and the opening of convergence part 121 is increased to the back-end gradually by the front end of axle body 1, and to hold oily portion 122 be plane with the joint of the ear end face of axle body 1.
By adopting technique scheme, it is large that convergence part becomes gradually, the mobile effect of playing acceleration that can be to lubricant oil, when lubricant oil enters relatively large space in less space, can produce the internal force of pullling between lubricant oil, be convenient to flowing of lubricant oil, hold oily portion and can hold oil processing to lubricant oil, and the joint of holding the ear end face of oily portion and axle body is plane, guaranteed that lubricant oil is difficult for running off, topology layout is more reasonable, for follow-up fuel feeding provides basis.
In the utility model specific embodiment, the stepped structure in the back side of described guide portion 2 and guiding breach 11; The degree of depth of described guiding breach 11 is less than or equal to the radius of axle body 1.
By adopting technique scheme, step structure is when assembling, the manual contact position of the flat position of perception axle and foreign object, further improved efficiency of assembling, and the degree of depth of guiding breach is less than or equal to the radius of axle body, when having improved efficiency of assembling, guaranteed the join strength of guide portion and axle body.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
