Background technique
Coupling is mainly used in the connection in the mechanical transmission, is the major part in the mechanical transmission, and its effect is that connection driving shaft and driven shaft move and moment of torsion to transmit.Existing coupling is generally key and connects, so that coupling bears the ability of alternate load and impulsive load is less, the torque that can bear is also less, does not have good precision simultaneously, radially with angle journal offset poor performance.
A kind of improvement as the key transmission, traditional swelling cover diaphragm-type coupling uses the swelling cover to hold shaft drive tightly, but the plate spring groups in it can't satisfy intensive work demand and long-time the use, in case diaphragm deforms or ruptures, can constitute a threat to personal security, and the inconvenience of diaphragm-type coupling installing/dismounting is overlapped in traditional swelling, concentricity is not high.
Summary of the invention
The purpose of this utility model is at the technological deficiency that exists in the prior art, and provides a kind of safety and long service life can realize transmitting greatly moment of torsion transmission and high one-piece type high rigid coupling of replying.
For realizing that the technological scheme that the purpose of this utility model adopts is:
A kind of one-piece type high rigid coupling, comprise that the center is formed with the cylindrical body of axial hole, correspondence is formed on the T-slot at cylindrical body two ends, described T-slot comprise be communicated with side and through hole and with cylindrical body axially vertical curve bath and setting vertically and with the straight trough that the curve bath center intersects vertically, between the body of described straight trough both sides, be formed with locking mechanism.
Described through hole cross section is the convex shape structure to connect the axle of different-diameter.
Described locking mechanism comprises the counterbore that is formed on the straight trough one side body, is formed on the straight trough opposite side body and the tapped hole corresponding with described counterbore and can pass counterbore and cooperate with the lock bolt with the axis clamping in the through hole with tapped hole.
Described locking mechanism comprises the counterbore that is formed on the straight trough both sides respectively accordingly, and lock bolt and locking nut, described lock bolt pass two counterbores and cooperate with locking nut with the axis clamping in the through hole.
And being provided with at least three, the compartment of terrain can be held the also dog hole of rotating joint at described body outer circumferential face by the utensil hook
Compared with prior art, the beneficial effects of the utility model are:
Coupling of the present utility model is at two ends designing T groove and locking mechanism, make and effectively to hold the mandrel transmission tightly by the deformation at notch place, adopt the integral type design of innovation higher than traditional diaphragm type structure reliability, rigidity is better, more can avoid because of diaphragm crack or any form to the infringement of coupling.Adopt the integral type design simultaneously, simple in structure, need not safeguard to have the torsional rigid of maximum level all the life, the realization height is replied, no back clearance, low inertia, high reliability, high concentricity is best suited for the coupling that machine actuating motor and stepper motor use.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in Fig. 1-4, one-piece type high rigid coupling of the present utility model, comprise that the center is formed with the cylindrical body 1 of axial hole, correspondence is formed on the T-slot at cylindrical body two ends, described T-slot comprise be communicated with side and the curve bath 2 of through hole and setting vertically and with the straight trough 3 that the curve bath center intersects vertically, between the body of described straight trough both sides, be formed with locking mechanism.Wherein, described through hole cross section is the convex shape structure to connect the axle of different-diameter.For guaranteeing the intensity of coupling, described straight trough only is opened in curve bath one side, to the fluting of the opposite side on the body, has not avoided overall performance influenced, guarantees product quality.
Two ends adopt the T-slot design to give the body end amount of deformation, can the axis clamping in the through hole can be realized transmission, the use of having save key by the deformation of end by locking mechanism.Adopt the integral structure design can effectively reduce the volume of coupling simultaneously, can realize that transmission moment of torsion and the height of similar maximum replied, have characteristics such as high reliability, low inertia.Moreover reduced volume can be carried out high-accuracy control, can realize that concentricity is below 3um.Be that transmission of power adopts frictional engagement to transmit, there is not back clearance, the precision height, speed is fast, can transmit bigger moment of torsion and axial force, can bear alternate load and impulsive load, can bear bigger torque with the less diameter of axle, can be widely used in the occasion that coaxality is had relatively high expectations, the coupling that the most suitable machine actuating motor and stepper motor use.
As depicted in figs. 1 and 2, the locking mechanism of the utility model first embodiment's one-piece type high rigid coupling comprises the counterbore 5 that is formed on the straight trough one side body, is formed on the straight trough 3 opposite side bodies and the tapped hole 6 corresponding with described counterbore and can pass counterbore and cooperate with the lock bolt 7 with the axis clamping in the through hole with tapped hole.Utilize the counterbore design can guarantee the surface of contact of bolt head, utilize bolt sealed with cooperating the straight trough opening of tapped hole, can contact its deformation and hold axle tightly the realization transmission.
Fig. 3 and Figure 4 shows that second embodiment of the present utility model, as shown in the figure, the locking mechanism of present embodiment comprises counterbore 8 and the counterbore 9 that is formed on the straight trough both sides respectively accordingly, lock bolt 10 and locking nut 11, described lock bolt passes two counterbores and cooperates with locking nut with the axis clamping in the through hole, utilize the hole countersunk design to guarantee the stress surface of screw bolt and nut, adopt screw bolt and nut to cooperate shaft locking, can effectively avoid coupling in rotation or rise suddenly or all standing produces produce when impacting loosening, improve running stability.
For ease of when mounted, especially be convenient to the practicality of spanner during clamping bolt, also be provided with at least three and can be held by the utensil hook and the dog hole of rotating joint in the compartment of terrain at described body outer circumferential face.Employing instrument hook is held and is rotated coupling, can be in installation process real-time convenient adjustment installation position, guarantee the operability of installing.
The above only is preferred implementation of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
