Description

Flexible coupling

Technical field

The utility model relates to field of machining and machinebuilding technology, in particular for the flexible coupling that is connected between axle and the axle.

Background technique

In the existing industrial production technology, precise rotation accessory that often need to some are lighter and handier is connected with slewing gears such as electric machine main shafts, thereby realize connecting two axles in the different institutions, make it jointly to rotate with transmitting torque, and in the power transmission of high-speed overload, playing buffering, damping and raising axle is the effect of dynamic performance.

At present, when using mandrel clamping gear grinding, usually adopt workpiece head, tailstock center to head on respectively the center hole at mandrel two ends, carry out centralized positioning, adopt simultaneously driving lever, shifting fork structure to carry out transmission of torque.There is following shortcoming in this structure:

(1) when not connecting firmly, driving lever, shift fork can only bear unidirectional torque;

(2) malalignment because of work spindle axis and the top on line of head, tail frame can produce the moment of flexure interference when driving lever, shift fork connect firmly, thus the indexing accuracy when affecting gear grinding;

(3) driving lever, the phase place of gear is accurately located.

The model utility content

The applicant provides a kind of flexible coupling rational in infrastructure for above-mentioned shortcoming of the prior art, thereby can make the again fast glitch-free transmission of carrying out torque when workpiece is top feels relieved with the mandrel center hole.

The technological scheme that the utility model adopts is as follows:

A kind of flexible coupling, described coupling are cylindrical, and described coupling outer peripheral surface is along axially being evenly distributed with the interlaced line of rabbet joint of many groups, and the two ends of described coupling are respectively arranged with axis hole; Bottom, described coupling two ends is respectively arranged with bolt hole.Its further technological scheme is:

Described coupling outer peripheral surface is provided with the interlaced 90 ° lines of rabbet joint of many groups, and every group is comprised of the 3-5 bar line of rabbet joint, and described line of rabbet joint axial displacement equi-spaced apart is cut to diameter from cylindrical;

Axis hole place, described coupling two ends has respectively notch;

Described coupling adopts aluminum alloy material.

The beneficial effects of the utility model are as follows:

The utility model adopts integral body to process, and has that volume is small and exquisite, simple in structure, transmitting torque large, without reversing the advantage such as return difference, can adapt to the connection of two transmission shafts of certain limit out-of-alignment.

The metallic elastic coupling that the utility model is formed in one, owing to having cut the line of rabbet joint in the middle of the coupling, make coupling form the flexibility function of soft waist, and produced flexible effect, can compensate radially, angle, axial deviation, and in use non-maintaining, anti-oil and corrosion resistant effect, coupling adopts aluminum alloy material, increase moment of torsion ability to bear and rigidity, be widely used in the connections such as stepper motor, encoder, screw rod transmission, platform of machine tool.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As depicted in figs. 1 and 2, a kind of flexible coupling, coupling 1 is cylindrical, coupling 1 outer peripheral surface is along four lines of rabbet joint 2 that axially are evenly distributed with one group of interlaced 90 ° of cutting, the distance that the interval equates between each bar line of rabbet joint 2 is cut to diameter from cylindrical, thereby guaranteed the intensity of coupling, specifically, referring to Fig. 3, article one, weld seam cuts out the semicircle of 0～180 degree, the second weld seam cuts out the semicircle of 90～270 degree, and the 3rd weld seam cuts out the semicircle of 180～360 degree, and the 4th weld seam cuts out the semicircle of 270～90 degree.According to the required flexible difference of different occasions, many group slots can be set, the distance between every slot also can be set different length; The two ends of coupling 1 are respectively arranged with axis hole 4, and axis hole 4 is through hole; Bottom, coupling 1 two ends is respectively arranged with bolt hole 5, and axis hole place, coupling 1 two ends has respectively notch 3, can regulate the size of notch, to adapt to flexibly the diameter of required connection diaxon, by adjusting bolt 6, thereby required connection diaxon is clamped respectively, couple together; Coupling 1 body can adopt aluminum alloy material, increases moment of torsion ability to bear and rigidity.

In the actual course of working, the coupling of different size mills out the line of rabbet joint according to the plate-like milling cutter of the large minor radius of difference, during installation, between the two ends difference centering input shaft and output shaft with coupling, and guarantee diaxon angle deviation, and the bolt of an end is tentatively tightened, then slightly rotating coupling makes it recover the flexible state of nature, then with the other end bolton, that bolts at two ends is further fastening, make its solid and reliable connection.

In the using process, because coupling is provided with slot, coupling has preferably flex capability, has then produced flexible effect in rotary course, can compensate radially, angle, axial deviation; Because each slot place also has the connection of the circular sector area of half at least, so can guarantee to transmit enough torques.

Above description is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
