Description
Technical field
The utility model relates to the coupling technical field, particularly relates to the high rigid coupling of a kind of swelling cover type.
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 the high high rigid coupling of swelling cover type of replying.
For realizing that the technological scheme that the purpose of this utility model adopts is:
The high rigid coupling of a kind of swelling cover type, comprise intermediate and left flange cover and the right flange cover that can fixedly connected with intermediate respectively, wherein, described intermediate center is formed with through hole, be provided with left tapered sleeve and right tapered sleeve coaxially in described intermediate both sides and described through hole, described left flange cover and right flange put and are respectively arranged with the conical through-hole corresponding with described left tapered sleeve and right tapered sleeve.
The tapering of described left tapered sleeve and right tapered sleeve is at 1/12-1/8.
The tapering of described left tapered sleeve and right tapered sleeve is 1/10.
Be provided with bolt hole on the described intermediate left and right side respectively equably, described left flange cover and right flange put and are formed with the through hole corresponding with described bolt hole and to utilize bolt itself and intermediate are fixed.
Put at described left flange cover and right flange and also to be respectively arranged with quick detachable mechanism, described quick detachable mechanism comprises that at least two are arranged on the tapped hole that left and right sides flange puts and the bolt that mates with described tapped hole symmetrically.
And being provided with at least three, the compartment of terrain can be held the also dog hole of rotating joint at described intermediate 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 has redesigned the tapering of intermediate and flange cover, it is more evenly distributed by the deformational stress that the swelling cover produces when tightening pressurization bolt, can effectively hold the mandrel transmission tightly, 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.
Description of drawings
Fig. 1 is the structural drawing of the high rigid coupling of swelling cover type of model utility;
Fig. 2 is the lateral plan of the high rigid coupling of swelling cover type of model utility.
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.
As illustrated in fig. 1 and 2, the high rigid coupling of swelling cover type of the present utility model, comprise intermediate 5 and the left flange cover 3 that can fixedly connected with intermediate respectively and right flange cover 4, wherein, described intermediate center is formed with through hole 6, be provided with left tapered sleeve 51 and right tapered sleeve 52 coaxially in described intermediate both sides and described through hole, be respectively arranged with the conical through-hole corresponding with described left tapered sleeve and right tapered sleeve on described left flange cover 3 and the right flange cover 4.
Wherein, the tapering of described left tapered sleeve and right tapered sleeve is at 1/12-1/8, preferably, the tapering of described left tapered sleeve and right tapered sleeve is 1/10, simultaneously it extends axially direction and is provided with 4 flutings symmetrically to allow the deformation of tapered sleeve in described left tapered sleeve and right tapered sleeve upper edge, adopt the tapered sleeve design of big tapering, it produces distortion by the swelling cover and obtains more uniform stress distribution when tightening pressurization bolt, can effectively hold mandrel tightly, adopt big tapering can effectively reduce the volume of coupling simultaneously, adopt two flange covers and an intermediate to form the ultrahigh rigidity coupling simultaneously, transmission moment of torsion and the height of the similar maximum of energy realization are replied, and have high reliability, characteristics such as low inertia.Moreover reduced volume can be carried out high-accuracy control, can realize that concentricity is below 3um.
Namely, make flange plate expansion set generation distortion and then hold axle tightly by tightening pressurization bolt, transmission of power adopts frictional engagement to transmit, and does not have 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.
Specifically, be provided with bolt hole 2 on the described intermediate left and right side respectively equably, certain described bolt hole also can adopt the through design that runs through the left and right side, and described left flange cover and right flange put and be formed with the through hole corresponding with described bolt hole by bolt itself and intermediate are fixed.Adopt on the side fixed structure is set, when not influencing bulk strength, effectively cancelled fastening flange, reduce volume and economical with materials, improve product competitive ability.
