Description

A kind of shaft coupling
Technical field
The present invention relates to a kind of new structural shaft couplings, belong to mechanical transmission fields.
Background technique
The shafting connection major way of current non-whole section of flange arrangement is separable coupling, and structure is as shown in Figure 1, axis It is connected between section 8 and shaft coupling 9 by key 10, which needs in 9 inner hole of 8 outer circumference surface of shaft part and shaft coupling Keyway is processed, it is close by the identical circular conical surface of taper to transmit torque, shaft part 8 and shaft coupling 9 by the key 10 that is arranged in keyway It fits together, is fixed by the locking effect of shaft end nut 11, which is primarily present following several respects defect:
(1) 8 excircle of shaft part and 9 inner hole of shaft coupling need to process circular conical surface and keyway, and drive mechanism design is complicated, and occupies Space is larger.
(2) when shaft coupling 9 and shaft part 8 are installed, Cone fit face and keyway position are both needed to artificial bedding-in, and required precision is high, It is great in constructing amount.
(3) in shafting transmission process, if there is 11 loose phenomenon of shaft end nut, connection fastener 12 need to be dismantled, by axis System's play whole in the axial direction re-secures shaft end nut 11 after going out construction space, and it is wider to involve works scope, construction Amount is big.
Summary of the invention
In view of this, the present invention provides a kind of shaft coupling, the fast and reliable connection of two sections of transmission shafts can be realized, and adjust It is convenient, high reliablity.
The shaft coupling includes: two clamping caps, elastic compression set and connecting component;Two shaft parts difference to be coupled For axis A and axis B;
The butt end of the axis A and axis B is coaxially located in the centre bore of the elastic compression set;
The outer circumference surface of the elastic compression set is two sections of conical surfaces axially docked, and the big end of two sections of conical surfaces is opposite;Two The inner hole of a clamping cap is bellmouth, is set in elastic compression and covers on external two sections of conical surfaces, with formation elastic compression set Two sections of conical surfaces of outer circumference surface are bonded;It is connected between two clamping caps by more than one connecting component, and two clamping caps Axial gap is reserved between opposing end surface.
Further, the connecting component includes attachment bolt and fastening nut;More than one is provided on clamping cap Bolt hole, attachment bolt pass through the corresponding bolt hole of two clamping caps and connect two clamping caps, and by cooperating with attachment bolt Fastening nut locking.
Further, the elastic compression set is manufactured by elastic alloy material.
The utility model has the advantages that
(1) shaft coupling compresses effective connection that the frictional force generated realizes two sections of axis, coupling structure letter by resilient sleeve Single, high reliablity does not need that keyway and driving key are arranged in shafting and coupling structure, and since clamping sleeve has certain bullet Property, it is not high to the requirement on machining accuracy on shaft part surface.
(2) shaft coupling and shafting are coupled by way of resilient sleeve swelling, therefore during installation, shafting surface be not necessarily into The processing of row bedding-in, easy for installation, labor intensity is low.
(3) when traditional shaft coupling and shafting connection loosen, shafting need to be dismantled and re-secure end face locking nut, in the present invention The fastening of shaft coupling is realized by the pressing force of attachment bolt, is directly passed through when there is loose phenomenon and is further fastened spiral shell Mother can eliminate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of traditional separable coupling;
Fig. 2 is the axial sectional structure chart of shaft coupling of the invention.
Wherein: 1- axis A, 2- attachment bolt, the left side 3- clamping cap, 4- elastic compression set, the right side 5- clamping cap, 6- fasten spiral shell Mother, 7- axis B, 8- shaft part, 9- shaft coupling, 10- key, 11- shaft end nut, 12- couple fastener
Specific embodiment
With reference to the accompanying drawings and examples, the present invention is described in further detail.
The present embodiment provides a kind of novel coupler structures, and the frictional force generated is compressed by resilient sleeve and realizes shafting Effectively connection, coupling structure is simple, and easy to adjust.
As shown in Fig. 2, the shaft coupling includes: attachment bolt 2, left side clamping cap 3, elastic compression set 4, right side clamping cap 5 With fastening nut 6.
Wherein elastic compression set 4 is manufactured by elastic alloy material, and inner peripheral surface is cylindroid, both ends respectively with need by Two shaft part axis A1 and axis the B7 cooperation of connection, the i.e. butt end of axis A1 and axis B7 are coaxially located at respectively in elastic compression set 4 In heart hole.Elastic compression covers 4 outer circumference surfaces and is made of two sections of symmetrical conical surfaces, i.e. the big end of two conical surfaces in left and right is opposite, The elastic compression 4 outer circumference surface both ends diameters of set being consequently formed are small, and mid diameter is big.
Left side clamping cap 3 and right side clamping cap 5 are sleeved on outside elastic compression set 4, left side clamping cap 3 and right side clamping cap 5 inner hole is bellmouth, and the inner hole conical surface of left side clamping cap 3 and right side clamping cap 5 covers 4 outer circumference surfaces with elastic compression respectively Left and right section cone match.
Axially and symmetrically, internal structure is and elastic compression covers 4 corresponding ends and matches for left side clamping cap 3 and right side clamping cap 5 Taper, between left side clamping cap 3 and right side clamping cap 5 reserve axial gap, the axial gap be left and right side clamping cap in axis The stroke space moved up.
More than two corresponding bolts hole, connection are provided on the circumferencial direction of left side clamping cap 3 and right side clamping cap 5 Bolt 2 passes through the corresponding bolt hole of left and right side clamping cap, connection left side clamping cap 3 and right side clamping cap 5.When rotation and couple When 2 matched fastening nut 6 of bolt, left side clamping cap 3 and right side clamping cap 5 go in the same direction under the action of bolt pretightening, Its conical inner hole generates extrusion effect to elastic compression set 4 in axial displacement process, produces elastic compression set 4 radially Swelling, finally realize the positive connection of two sections of coupled axis A1 and axis B7.
To sum up, the above is merely preferred embodiments of the present invention, it is not intended to limit the scope of the present invention.It is all Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the invention Within the scope of.
