Abstract
The utility model provides a multi-groove miniature shaft which comprises a cylindrical shaft body, wherein two rectangular grooves and two V-shaped grooves are formed in the shaft body; the two rectangular grooves are symmetrically formed in two sides of the shaft body; the two V-shaped grooves are adjacent to each other and are positioned between the end part of the shaft body and one rectangular groove; multiple micro oil pits are formed in an outer wall, which is positioned between the two rectangular grooves, on the shaft body. According to the multi-groove miniature shaft, the multiple micro oil pits are formed in the outer wall of the shaft body, lubricating oil is filled in the micro oil pits, the lubricating conditions in the process of operating the multi-groove miniature shaft can be obviously improved, and the service life of the multi-groove miniature shaft is prolonged.
Description
Technical field
The utility model belongs to Minisize axial field, is specifically related to a kind of multiple-grooved Minisize axial.
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.
Multiple-grooved Minisize axial belongs to a kind of of Minisize axial, and lubricated mainly the relying on axle when at present traditional multiple-grooved Minisize axial 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 a kind of lubrication effect better multiple-grooved Minisize axial.
The utility model is achieved by the following technical solution:
A kind of multiple-grooved Minisize axial, it is characterized in that, comprise columniform axle body, on described axle body, be provided with two rectangle grooves and two V-type grooves, described two rectangle grooves are symmetricly set on the both sides of axle body, described two adjacent settings of V-type groove, and all between the end and a rectangle groove of axle body; On described axle body, on the outer wall between two rectangle grooves, be provided with several fine oil holes.
Further setting of the present utility model is, described several fine oil holes are uniformly distributed.
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 two ends of described axle body are provided with chamfering.
Multiple-grooved Minisize axial described in the utility model processes several fine oil holes by the outer wall at axle body, and fills lubricant oil, the lubrication circumstances in the time of can significantly improving the work of multiple-grooved Minisize axial, the working life of improving multiple-grooved Minisize axial in fine oil hole.
Accompanying drawing explanation
Fig. 1 is the structural drawing of multiple-grooved Minisize axial described in the utility model.
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 multiple-grooved Minisize axial, comprise columniform axle body 1, on described axle body 1, be provided with two rectangle grooves 2 and two V-type grooves 3, described two rectangle grooves 2 are symmetricly set on the both sides of axle body 1, described two adjacent settings of V-type groove 3, and all between the end and a rectangle groove 2 of axle body 1; On described axle body 1, on the outer wall between two rectangle grooves 2, be provided with several fine oil holes 4.Described several fine oil holes 4 are uniformly distributed.The diameter in described fine oil hole 4 is 0.01～0.05mm.Wherein, the setting of rectangle groove 2 is that the setting of V-type groove 3 is more accurate in order to locate for the ease of the component such as jump ring are installed.
For the ease of assembling, the two ends of described axle body 1 are provided with chamfering 5.
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.
