Abstract
The utility model provides a flat position shaft. The flat position shaft comprises a cylindrical shaft body, wherein one end of the shaft body is provided with a locating gap along the axial direction, and the depth of the locating gap is less than the radius of the body; the external wall of the shaft body is provided with a plurality of superfine oil pits. The flat position shaft provided by the utility model is provided with the plurality of superfine oil pits formed in the external wall of the shaft body, and the superfine oil pits are filled with lubricating oil, so that the lubrication condition of the flat position shaft during work can be improved obviously, and the service life of the flat position shaft is prolonged.
Description
Technical field
The utility model belongs to Minisize axial field, is specifically related to a kind of flat position 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.
Flat position axle belongs to a kind of of Minisize axial, and lubricated mainly the relying on axle when at present traditional flat position axle is worked offered oil groove, stores lubricant oil and realizes.But the mode lubrication effect of this Sump lubrication is not very desirable.
Model utility content
The utility model, for above-mentioned the deficiencies in the prior art, provides the better flat position of a kind of lubrication effect axle.
The utility model is achieved by the following technical solution:
A flat position axle, is characterized in that, comprise columniform axle body, one end of described axle body is provided with a locating notch along axial direction, and the degree of depth of described locating notch is less than the radius of axle body; On the outer wall of described axle body, be provided with several fine oil holes.
Further setting of the present utility model is, described fine oil hole evenly spreads on the outer wall of axle body.
Further setting of the present utility model is, the diameter in described fine oil hole is 0.01～0.05mm.
Further setting of the present utility model is, the back side of described locating notch is provided with a draw-in groove along axle body radial direction.
Flat position described in the utility model axle processes several fine oil holes by the outer wall at axle body, and fills lubricant oil in fine oil hole, the lubrication circumstances in the time of can significantly improving the axle work of flat position, the working life of improving flat position axle.
Accompanying drawing explanation
Fig. 1 is the structural drawing of flat position described in the utility model axle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model provides a kind of flat position axle, comprises columniform axle body 1, and one end of described axle body 1 is provided with a locating notch 2 along axial direction, and the degree of depth of described locating notch 2 is less than the radius of axle body 1; On the outer wall of described axle body 1, be provided with several fine oil holes 3.Described fine oil hole 3 evenly spreads on the outer wall of axle body 1.The diameter in described fine oil hole 3 is 0.01～0.05mm.
For the ease of the parts such as jump ring are installed, the back side of described locating notch 2 is provided with a draw-in groove 4 along axle body radial direction.
It is apparent to one skilled in the art that the utility model can be changed into various ways, and such change is not thought and departed from scope of the present utility model.All so apparent modifications of the technician to described field, within being included in the scope of this claim.
Claims (4)
1. a flat position axle, is characterized in that, comprise columniform axle body, one end of described axle body is provided with a locating notch along axial direction, and the degree of depth of described locating notch is less than the radius of axle body; On the outer wall of described axle body, be provided with several fine oil holes.
2. flat position according to claim 1 axle, is characterized in that, described fine oil hole evenly spreads on the outer wall of axle body.
3. flat position according to claim 1 axle, is characterized in that, the diameter in described fine oil hole is 0.01～0.05mm.
