Abstract
The utility model relates to a conical bolt component for shearing and transmitting torque, in particular to the connection between two parts which are applicable to torque transmission. A conical pin is fitted into a conical sleeve, a concave washer is arranged in the head of the conical sleeve and screwed into a bolt body. The inner surface of the conical sleeve and the outer surface of the conical pin are in taper fit, and the concave washer and the conical sleeve are in clearance fit. The center of the concave washer is provided with a hole, and the bolt passes through the hole and is connected with a threaded hole in the center of the conical pin. A hexagon hole is processed in the center of the head of the conical pin, and a plurality of threaded holes are drilled on an end surface. Lubricating coatings are sprayed on the inner conical surface of the conical sleeve and the outer conical surface of the conical pin. The conical bolt component has simple and reasonable structure, is convenient to install and use, significantly reduces the installation difficulty, can fully eliminate the connection gap, has good positioning precision, can improve the bearing status of the bolt, and can effectively improve the service life of the bolt.
Description
Technical field
The utility model relates to a kind of shearing torsion pass with a kind of awl bolt assembly, specifically is applicable to the connection between two parts of transmitting torque.
Background technique
In prior art, two parts of transmitting torque generally adopt the friction bolt or shear Bolt Connection.Friction torsion pass Bolt Connection is gapped, and Location accuracy is low, can only be used for slow-speed of revolution occasion, if be applied to high-speed equipment, then owing to keeping lower imbalance to produce vibration problem.It is higher to shear torsion pass bolt Location accuracy, can be used for high rotating speed equipment, but has 2 deficiencies: the one, and connect and still have slight clearance, can't eliminate fully, thereby not only be subjected to shearing when causing the bolt torsion pass, also be subjected to the moment of flexure effect; The 2nd, larger-size bolt is installed difficulty, not only wears the bolt effort, because the screw-down torque that requires is big, relies on manpower can't tighten when the more important thing is fastening nut at all.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of can the elimination fully to connect gap, simple load and unload torsion pass with boring bolt assembly.
According to the technological scheme that the utility model provides, a kind of awl bolt assembly comprises the body of bolt, and feature is: also wrap according to cupped washer, tapered sleeve, taper pin, described taper pin penetrates tapered sleeve, with the cupped washer tapered sleeve head of packing into, is screwed into the body of bolt again.
Described tapered sleeve internal surface and taper pin outer surface are cone match, and cupped washer and tapered sleeve are Spielpassung.
Described cupped washer center is provided with the hole, and bolt passes this hole and connects with the tapped hole at taper pin center.
Described taper pin head center is processed with inner hexagonal hole, and end face is drilled with some tapped holes.
Described tapered sleeve inner conical surface and taper pin male cone (strobilus masculinus) are coated with lubricant coating.
Compared with the prior art the utility model has the following advantages:
1, the utility model is simple and reasonable, and is easy to install, can significantly reduce installation difficulty.
2, can eliminate the connection gap fully, have good Location accuracy.
3, the load situation of bolt can be improved, the working life of bolt can be improved effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: the awl bolt comprises the body of bolt 1, cupped washer 2, tapered sleeve 3, taper pin 4.Described tapered sleeve 3 internal surfaces and taper pin 4 outer surfaces are cone match, and cupped washer 2 is little Spielpassung with tapered sleeve 3.Cupped washer 2 centers are porose, and the body of bolt 1 passes this hole and connects with taper pin 4.
When the utility model is installed, earlier tapered sleeve 3 is penetrated the torsion pass hole on coupled part A, the B, then taper pin 4 is penetrated tapered sleeve 3, with cupped washer 2 tapered sleeve 3 heads of packing into, be screwed into the body of bolt 1 again, the screw-down torque body 1 that tights a bolt gets final product in accordance with regulations.During work, moment of torsion is delivered to the awl bolt from part A, passes to part B again, and the awl bolt is subjected to shearing force under the effect of moment of torsion.
Described tapered sleeve 3 adopts Spielpassung with the torsion pass hole on coupled part A, the B, so that install.After the installation, because the tension effect of the body of bolt 1, taper pin 4 is tapered sleeve 3 outside distendings, thereby eliminates the gap in tapered sleeve 3 and torsion pass hole and produce certain tension force.Like this, awl bolt and coupled part have good location, can the balance of equipment not had a negative impact.Simultaneously because torsion pass connects no gap, during transmitting torque, bore and only bear shearing stress on the bolt and do not have bending moment, thereby can improve the load situation of bolt, can improve the working life of bolt effectively.Since still can positive connection when the awl bolt, can guarantee that part A and part B are subjected to axial withdrawal power with the torsion pass hole swelling of part A and part B, under the situation of the equal linking intensity of assurance, boring the required screw-down torque of bolt only is 1/3～1/5 of plain bolt; Simultaneously, the Dimensions of the body of bolt 1 is about 1/3 when adopting plain bolt, has significantly reduced installation difficulty.On main equipment, adopt plain bolt can't lean on the manpower fastening nut at all, can only be by means of special tool, the utility model provides a solution.
During dismounting, earlier the body of bolt 1 is unclamped, take off cupped washer 2, in the tapped hole of taper pin 4 heads, be screwed into several bolts then, taper pin 4 is ejected from tapered sleeve 3 by tighting a bolt.After taper pin 4 withdrawed from, no longer swelling of tapered sleeve 3 can easily be taken out from the torsion pass hole.
For the ease of dismounting, can on the conical surface of tapered sleeve 3, taper pin 4, spray lubricant coating, to reduce both friction factor, the ejecting force when reducing to dismantle.
