Abstract
The utility model relates to an integral elastic coupler, which comprises a through groove with a starting end with n >2 big semi-circle rings in the middle part and an ending end with small through holes. A long through hole for the insertion of two connected axles is arranged along the longitudinal direction of a central axis of a coupling body, and a central line of the long through hole is mutually coincident with the central axis of the coupling body. In addition, the side walls of both ends of the coupling body are respectively provided with three uniformly distributed screw holes for fixing screw nails. With the integral simple connection structure, the utility model realizes the relative parallel displacement and the relative angular discrepancy of two compensation axles of the coupler in connection. With the through groove with small through holes in the middle part of the coupling body, the functions of moderating shock and changing axis series natural vibration frequency are realized.
Description
The utility model is a kind of integral type elastic coupling flexible coupling.Be mainly used in the precision instrumentation transmission.
Prior art: coupling is mechanically operated common components, is mainly used to connect driving shaft and driven shaft, with transmitting movement and torque.Because diaxon manufacturing and installation errors that coupling connected, influences such as distortion after the carrying and surrounding environment such as temperature variation often can not guarantee strict centering, but exist relative displacement to a certain degree.Therefore require coupling to have the space relative displacement that compensates diaxon, the function of buffering, vibration damping and carry-over moment.Coupling commonly used has: sliding cross coupling, Hooks coupling universal coupling, rubbercushioned sleeve bearing coupling etc., and they can realize the fundamental function of coupling, but structure is relatively complicated, is processed with certain degree of difficulty, and using has certain narrow limitation.For example: sliding cross coupling is applicable to medium rotating speed, the occasion of no severe impact; Hooks coupling universal coupling is applicable to the slow-speed of revolution, and diaxon has the occasion than mitre; And diaphragm coupling is applicable to that torsional elasticity is lower, the occasion of load ratio high speed transmission more stably.
The purpose of this utility model is in order to overcome the deficiency of prior art, to provide a kind of simple in structure, easy to process, is convenient to install, and need not lubricate, and balance is easy, and using effect is good, the integral type elastic coupling flexible coupling that the life-span is long.
The structure of the utility model integral type elastic coupling flexible coupling such as Fig. 1, Fig. 2, shown in Figure 3.Comprise have respectively on top that the intermediate portion has the shaft coupling body 1 of n＞2 a big semicircle annular through groove 2, a groove 2 and the terminal two ends sidewall that small through hole 3, shaft coupling body 1 all arranged 3 by the center line space be 120 ° of uniform confessions screw 4 of being connected axle and shaft coupling body 1 and being fixed together, along the central axis OO of shaft coupling body 1 vertically on have for the long through-hole 5 that is connected the diaxon insertion, the center line OO of long through-hole 5 overlaps with the central axis OO of shaft coupling body 1.Groove 2 is formed by the line cutting process, the direction quadrature of line cutting fluting make it have certain elasticity, so groove 2 not only makes coupling in X-axis direction certain stretching, extension performance be arranged, and can compensate the opposing parallel displacement of Y-axis, Z axle, and around the relative angular displacement of X, Y, Z axle.The quantity of groove 2 is by the outer diameter D and the length L decision of shaft coupling body 1.The small through hole 3 at groove 2 two ends also is to be formed by the line cutting process, and it is evenly distributed on the shaft coupling body 1 stress, stress concentrate occur in small through hole 3 near, and sharply descend and tend towards stability from small through hole 3 stress far away slightly.Have 3 to be used for screw by the 120 ° of uniform screws 4 in center line space and to hold out against the diaxon that is connected on the shaft coupling body 1 two ends sidewall respectively, long through-hole 5 is to inject in the shaft coupling body 1 for connected diaxon to be connected.It is easy to process that the simple structure of the utility model can adopt the advantage of line cutting process to be, saves material, the efficient height, and also the surface quality of part is good.
Said shaft coupling body 1 is to adopt good toughness, wear-resisting, corrosion-resistant, and machinability is good, and the tin-phosphor bronze of certain intensity and hardness is arranged, perhaps No. 65 manganese steel (65Mn), and perhaps the high elasticity steel processes, and does corresponding surface treatment after the processing.
Advantage of the present utility model is: when two axles need connect, in the long through-hole 5 at shaft coupling body 1 two ends, inject respectively, with being screwed into 3 screws in 3 uniform on the sidewall of two ends screws connected diaxon and shaft coupling body 1 are fixed together respectively after the reeve, owing to there are the two ends of n＞2 a big semicircle annular to have the groove 2 of small through hole 3 on the intermediate portion of shaft coupling body 1, make it flexible, reduced stress, therefore opposing parallel displacement and relative angle displacement when the utility model has realized not only that with the simple linkage structure of integral type coupling compensation diaxon connects have reduced the requirement of diaxon installation precision and strict centering.Playing the mitigation impact and change axle by the groove 2 of being with small through hole 3 simultaneously is the effect of the natural frequency of vibration.The utility model has been used for the actual machine transmission, has proved above-mentioned advantage amply, and is simple in structure, easy to process, is convenient to install, and need not lubricate, and balance is easy, and the life-span is long, and using effect is good.
