Abstract
The utility model discloses a kind of expansion set, it relates to mechanical spare part in common use technical field, it comprises expansion set body, cavity and wearing layer, the inner hollow of expansion set body is provided with cavity, cavity surface layer is provided with wearing layer, sets up after wearing layer, at internal surface after expansion set contacts with internal orifice sizing die for a long time, can effectively prevent the internal surface wearing and tearing of expansion set, thereby extend the working life of expansion set.
Description
Technical field:
The utility model relates to expansion set, belongs to mechanical spare part in common use technical field.
Background technique:
Expansion set is for connecting driving shaft and the driven shaft in different institutions, makes it the mechanical parts of common rotation with transmitting torque, and telling in heavily loaded power transmission, it is the effect of dynamic performance that some expansion set also has buffering, vibration damping and raising axle.The long service life of expansion set, in the time of overload, expansion set will lose link effect, can be without prejudice by protection equipment.But in use, after internal orifice shaping grinding tool Long Term Contact, the internal surface of expansion set easily weares and teares expansion set, so just easily cause internal orifice shaping grinding tool to be damaged, shortened the working life of internal orifice shaping grinding tool and expansion set simultaneously.
Model utility content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of expansion set.
A kind of expansion set of the present utility model, it comprises expansion set body, cavity and wearing layer, and the inner hollow of expansion set body is provided with cavity, and cavity surface layer is provided with wearing layer.
As preferably, described expansion set body 1 is cylindrical body, and it is that 45 steel are made.
As preferably, described cavity 2 is cone-shaped.
As preferably, described wearing layer 3 is made for titanium material.
The beneficial effects of the utility model: it can overcome the drawback of prior art, set up after wearing layer at internal surface, after expansion set contacts with internal orifice sizing die for a long time, can effectively prevent the internal surface wearing and tearing of expansion set, thereby extend the working life of expansion set.
Brief description of the drawings:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the structural representation of the utility model expansion set;
1-expansion set body, 2-cavity, 3-wearing layer.
Embodiment:
As shown in Figure 1, this embodiment by the following technical solutions: it comprises expansion set body 1, cavity 2 and wearing layer 3, and the inner hollow of expansion set body 1 is provided with cavity 2, and cavity 2 surface layers are provided with wearing layer 3.
Wherein, described expansion set body 1 is cylindrical body, and it is that 45 steel are made; Described cavity 2 is cone-shaped; Described wearing layer 3 is made for titanium material.
The working principle of this embodiment is: expansion set connects with driving shaft and driven shaft respectively, make it jointly to rotate with transmitting torque, the axle of expansion set and the processing in hole are installed and unlike interference fit, require high-precision manufacturing tolerances, expansion set need not heat while installation, cooling or pressurized equipment, only need tighten bolt moment on request.And easy to adjust, wheel hub can be adjusted to easily on axle to desired location.Expansion set in use cavity 2 can contact with internal orifice shaping grinding tool, and under long-term extruding, the internal surface of expansion set wearing and tearing easily occurs or produces burr, thereby damages internal orifice shaping grinding tool.Increase after wearing layer 3 at expansion set internal surface, can effectively prevent that expansion set from damaging, thereby extend the working life of expansion set.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
