Description
Technical field
The utility model is related to special-shaped seamless steel pipe technical fields, more particularly, to a kind of three ear special-shaped seamless steel sleeves.
Background technology
Axis as transmission torque on farm machinery is mostly solid shafting, and solid shafting not only increases the weight of machinery,
And easily cause the waste of material.Hollow steel pipe is although light-weight, materials'use amount is few, but cannot be by due to its intensity is low
For transmitting torque.
Utility model content
The purpose of this utility model is to provide a kind of three ear special-shaped seamless steel sleeves, solves that solid transmission shaft weight is big, material
Expect the low problem of utilization rate.
To achieve the above object, the utility model provides a kind of three ear special-shaped seamless steel sleeves, including inner and outer tubes,
Said inner tube and the outer tube grafting, the outer surface of said inner tube are adapted with the inner surface configuration of the outer tube, the outer tube
Including ontology one and boss one, three boss one are uniformly distributed on the ontology one, the ontology one and the boss
One is smoothly connected by arc surface, and the external surface top of one of them boss one is provided with reference plane one, the reference plane
One is plane, and it is plane to be provided at the top of the inner surface of the boss one of the reference plane one also.
Preferably, the ontology one is cylindrical structure.
Preferably, said inner tube includes ontology two and boss two, and three boss two uniformly divide on the ontology two
Cloth, the ontology two are smoothly connected with the boss two by arc surface, and the external surface top of one of them boss two is set
It is equipped with reference plane two, the reference plane two is plane, and the width of the reference plane two, which is less than, is provided with the convex of the reference plane one
The width of one inner surface top planes of platform.
Preferably, the ontology two is cylindrical structure.
Preferably, the outer tube and said inner tube are solid drawn tube.
Three ears special-shaped seamless steel sleeve described in the utility model, one is evenly provided with 3 on cylindrical ontology
Boss one is also evenly provided with 3 boss two on cylindrical ontology two, and the use nested with boss two of boss one is for passing
Torque delivery, three boss one and boss two may be used to bear torque, and torsion is stronger, transmission is more stable.In the appearance of outer tube
It is provided with reference plane one on face, corresponding reference plane two is set on the outer surface of inner tube, reference plane one and reference plane two can be with
Assembling for casing, outer tube and inner tube provides benchmark and limit, facilitates installation.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Specific implementation mode
Embodiment
Fig. 1 is a kind of structural schematic diagram of three ears special-shaped seamless steel sleeve embodiment of the utility model, and Fig. 2 is that this practicality is new
A kind of outer tube cross-sectional structure schematic diagram of three ears special-shaped seamless steel sleeve embodiment of type.As shown in Figure 1 and Figure 2, a kind of three ears are different
Shape seamless steel casing, including inner tube 2 and outer tube 1, inner tube 2 are inserted into the internal cavities of outer tube 1, and outer tube 1 and inner tube 2 are to adopt
The solid drawn tube produced with cold-drawing technology.Inner tube 2 is independent separate structure, the outer surface of inner tube 2 and outer tube with outer tube 1
1 inner surface configuration is adapted, i.e., the outer surface of inner tube 2 is identical as the inner surface configuration of outer tube 1, but the ruler of 2 outer surface of inner tube
The very little size for being less than 1 inner surface of outer tube.Outer tube 1 includes ontology 1 and boss 1, and ontology 1 is the structure of cylinder,
3 boss 1 are uniformly distributed on ontology 1.Cylindrical ontology 1 is divided into 3 sections of arc surfaces, circular arc by boss 1
Face is spaced apart with boss 1, and arc surface is smoothly connected with boss 1.The external surface top of one of boss 1 is provided with
Reference plane 1, reference plane 1 are plane, and reference plane 1 provides benchmark, positioning for the installation of casing, facilitates the installation pair of casing
It connects.Reference plane 1 is unique plane on 1 outer surface of outer tube.It is provided at the top of the inner surface of the boss 1 of reference plane 1
For plane.
Fig. 3 is a kind of inner tube cross-sectional structure schematic diagram of three ears special-shaped seamless steel sleeve embodiment of the utility model.Such as
Shown in Fig. 3, inner tube 2 includes ontology 27 and boss 28, and ontology 27 is also the structure of cylinder, is uniformly divided on ontology 27
It is furnished with 3 boss 28.Cylindrical ontology 27 is divided into 3 sections of arc surfaces, arc surface and the interval point of boss 28 by boss 28
Cloth, arc surface are smoothly connected with boss 28.The external surface top of one of boss 28 is provided with reference plane 24, reference plane
24 be plane.Reference plane 24 provides benchmark and positioning for the installation of outer tube 1 and inner tube 2, facilitates the assembling of outer tube 1 and inner tube 2.
Reference plane 24 is unique plane on 2 outer surface of inner tube, and the width of reference plane 24 is less than the boss one for being provided with reference plane 1
The width of 6 inner surface top planes.The top for being provided with the inner surface of the boss 28 of reference plane 24 can be that arc surface also may be used
Think plane.
Therefore, the three ear special-shaped seamless steel sleeves of the utility model using the above structure, can solve solid transmission shaft weight
The problem that amount is big, stock utilization is low.
