Description

A kind of direct-connected shaft coupling
Technical field
It the utility model is related to shaft coupling field, and in particular to a kind of direct-connected shaft coupling.
Background technology
Shaft coupling is to be allowed to common rotation for coupling the two of different institutions axles (driving shaft and driven shaft) to transmit torsion The machine components of square, it is the important component of machine driven system.Shaft coupling can be made actively due to a variety of causes in the running The axle center of axle and driven shaft not on the same axis, so as to produce unbalanced centrifugal inertia force, centrifugation inertia idol power and dynamic deflection (vibration shape), these energy imbalances necessarily cause the vibration of shafting, so as to produce pedestal deformation, Bearing Grinding due to shafting stand under load The problems such as damage, axle fracture, influence the normal work and use life-span of equipment.
Conventional shaft coupling mainly has positive coupling and yielding coupling, and positive coupling is simple in construction, easy to manufacture, Maintenance cost is relatively low, but without buffering and cushioning effect;Yielding coupling generally includes elastomeric element, has buffering and damping Effect, therefore start frequent, positive and negative diverse high speed shaft and select yielding coupling more.But existing yielding coupling leads to Often complicated, installation and production requirement height, adaptability are poor.
Utility model content
Main purpose of the present utility model is to provide a kind of direct-connected shaft coupling, answered with solving existing coupler structure Miscellaneous, installation and the technical problem that production requirement is high, adaptability is poor.
The utility model realizes that the technical scheme of above-mentioned purpose is:A kind of direct-connected shaft coupling, it is characterised in that including two Structure identical half a coupler, the half a coupler offer centre bore in axial direction, an end of the half a coupler Have on face and be uniformly distributed and shape identical multiple arcs double wedge, the two sides of each arc double wedge are along direct-connected shaft coupling The plane of device radial direction, wherein, two half a couplers can be linked together by the clamping of respective arc double wedge; The opening position of keyway and the half a coupler in the middle part of keyway is offered in the centre bore of the half a coupler to offer vertically In the positioning jackscrew through hole of keyway.
Further, the quantity of the arc double wedge on each half a coupler is three, and each arc double wedge is around half a coupler The radian at center is 60 °.
Further, two sides of each arc double wedge of the half a coupler are provided with elastic insert.
Further, the elastic insert is rubber spacer.
Further, the half a coupler is formed using steel or aluminium alloy casting.
The beneficial effects of the utility model are:
1. direct-connected shaft coupling of the present utility model is made up of two structure identical half a couplers, by double wedge come to power Moment of torsion carries out face contact and transmitted, simple in construction.
2. direct-connected shaft coupling convenience quick for installation of the present utility model, improve the efficiency of production and installation and reduce peace Dress and the required precision of production.
3. the double wedge of the direct-connected shaft coupling of the utility model has surplus gap axially and radially simultaneously in the running, therefore Appropriate axial float and radial-play can be allowed simultaneously, increase the application of this direct-connected shaft coupling, while ensure to turn round The efficiency and stationarity of square transmission.

Embodiment
The technical solution of the utility model is described in detail below with reference to accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1 to Figure 3, the direct-connected shaft coupling of the present embodiment includes two structure identical half a couplers 1.Described half Shaft coupling 1 offers centre bore 3 in axial direction.In the present embodiment, have on an end face of the half a coupler equal Even distribution and three arc double wedges 4 of shape identical, radian of each arc double wedge 4 around the center of half a coupler 1 is 60 °.Another In one embodiment, the number of arc double wedge 4 can be two, and radian of each arc double wedge 4 around the center of half a coupler 1 is 90 °. In another embodiment, the number of arc double wedge 4 can be four, and radian of each arc double wedge 4 around the center of half a coupler 1 is 45°.When installing two half a couplers, three arc double wedges 4 of one and half shaft couplings are inserted respectively into the three of another half shaft coupling In gap between individual arc double wedge 4, because the two sides of each arc double wedge are along direct-connected shaft coupling radial direction Plane, forming face contacts between the arc double wedge 4 of different half a couplers, meanwhile, the arc double wedge 4 of different half a couplers 1 can In axial direction slightly move.In addition, after two half a coupler installations, circle is defined among the arc double wedge of mutual clamping The surplus gap of cylindricality, therefore two half a couplers also radially can be moved slightly.Therefore, the half of the direct-connected shaft coupling The arc double wedge 4 of shaft coupling 1 has surplus gap axially and radially simultaneously in the running, can allow appropriate axial direction simultaneously Play and radial-play, increase the stability in operation process.
Because the two sides of each arc double wedge 4 are along the plane of the radial direction of direct-connected shaft coupling, therefore, operating When, the contact between the arc double wedge 4 of different half a couplers 1 is face contact, add connect between two half a couplers 1 it is steady It is qualitative and reduce due to the impact in operation process and caused by abrasion.
In addition, offering keyway 7 in the centre bore 3 of the half a coupler 1, key 6 is arranged in keyway 7, for by axle It is fixedly connected with shaft coupling.In the present embodiment, opening position of the half a coupler 1 at the middle part of keyway 7 is offered perpendicular to key The positioning jackscrew through hole 2 of groove 7.Positioning jackscrew 5 is contacted by positioning jackscrew through hole 2 with key 6, and passes through screwed in place jackscrew 5 And axle will be tightly held with shaft coupling and be connected.
Two sides of each arc double wedge 4 of the half a coupler 1 are provided with elastic insert, in shaft coupling Enter row buffering and damping in operation process.In the present embodiment, the elastic insert is rubber spacer.In other embodiments, The elastic insert can be the bed course made of the material of any flexible performance.
In the present embodiment, the half a coupler 1 is formed using steel or aluminium alloy casting.
In use, first, on the premise of key 6 is placed in keyway 7, driving shaft and driven shaft are each passed through two The centre bore 3 of individual half a coupler 1;Then, two half a couplers 1 are connected by the 4 mutual clamping of arc double wedge on end Together;Finally, positioning jackscrew 5 is made axle and shaft coupling tightly holding company by positioning jackscrew through hole 2 and being tightened on key 6 Connect, so as to realize master by the clamping of the arc double wedge 4 of two half a couplers 1 and the fixation of each half a coupler 1 and axle Moving axis completes moment of torsion transmittance process with being rotated while driven shaft.Direct-connected coupler structure of the present utility model is simple, and installation is fast Victory is convenient, strong adaptability, can be widely applied to various power transmission process.
