Abstract
The utility model discloses a slider coupling, including half first slider coupling and second half slider coupling, it leads to the groove to be equipped with the straight line on the first half slider coupling terminal surface, the horizontal section size that the straight line leads to the groove is the same everywhere, be equipped with the protruding strip with recess matched with on half slider coupling of the second terminal surface, protruding strip leads to the groove block with the straight line, this slider coupling, first axis of rotation and second axis of rotation transmission in -process, because of vibration or clearance, or first axis of rotation and second axis of rotation axial lead be not same sharp and when receiving the radial force, half slider coupling of the relative second of half first slider coupling can follow the logical groove of straight line and make radial movement, and then cushion this radial force, avoid half first slider coupling and second half slider coupling because of receiving great radial force to cause the damage.
Description
Technical field
This utility model relates to a kind of shaft coupling, particularly relates to a kind of oldham coupling.
Background technology
In drive mechanism, the rotation between centers that two are coaxially disposed connects frequently with shaft coupling, so that two rotation axles rotate together with, completes the transmission of moment of torsion and motion. Tradition two rotates axle such as between motor output shaft and reductor shaft, conventional shaft joint is adopted to connect, carry out integral drive, the transmission process of this kind of connected mode, the axiality rotating axle to two requires higher, but owing in using, two rotate axles and there will be axial line unavoidably not at same straight line, or bearing the situation of radial force because of other outside causes, this situation very easily makes shaft coupling damage in transmission process.
Summary of the invention
The purpose of this utility model is in that to provide a kind of oldham coupling.
For realizing the purpose of this utility model, now describe its technical scheme in detail: a kind of oldham coupling, including the first half oldham couplings and the second half oldham couplings, the first half oldham couplings offer for being overlapped the first through hole being fixed on the first rotation axle, the first half oldham couplings are perpendicular to the end face of the first through-bore axis and are provided with straight line groove, the cross sectional dimensions of straight line groove is identical everywhere, the second half oldham couplings offer for being overlapped the second through hole being fixed on the second rotation axle, the second half oldham couplings are perpendicular to the end face of the second through-bore axis and are provided with the raised item with fit depressions, raised item engages with straight line groove.
Further, straight line conduit centrage is through the first through hole axial line, and straight line conduit is divided into the first half line conduit and the second half line conduit by the first through hole. Under this kind of connected mode, first rotates axle and second rotates between centers stress evenly.
This utility model oldham coupling, first rotates axle and second rotates in through-drive process, because of vibration or gap, or first rotate axle with second rotate axle axial line not at same straight line be subject to radial force time, relative the second half oldham couplings of the first half oldham couplings can linearly move radially by groove, and then this radial force is cushioned, the first half oldham couplings and the second half oldham couplings are avoided to cause damage because being subject to bigger radial force, this oldham coupling, between Hard link and between being flexible coupling, the machinery damage that Deviation of equipments causes can be made to be preferably minimized degree, first rotates axle and second rotates between centers stable transmission, improve integral device operational efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of this utility model oldham coupling is described in detail:
As shown in Figures 1 to 5, this utility model oldham coupling, including the first half oldham couplings 1 and the second half oldham couplings 2, the first half oldham couplings 1 offer for being overlapped the first through hole 11 being fixed on the first rotation axle 10, the first half oldham couplings 1 are perpendicular to the end face of the first through hole 11 axis and are provided with straight line groove 12, the cross sectional dimensions of straight line groove 12 is identical everywhere, the second half oldham couplings 2 offer for being overlapped the second through hole 21 being fixed on the second rotation axle 20, the second half oldham couplings 2 are perpendicular to the end face of the second through hole 21 axis and are provided with the raised item 22 matched with groove 12, raised item 22 engages with straight line groove 12. straight line conduit 12 centrage is through the first through hole 11 axial line, and straight line conduit 12 is divided into the first half line conduit 121 and the second half line conduit 122 by the first through hole 11.
This utility model oldham coupling, first rotates axle 10 and second rotates in axle 20 transmission process, because of vibration or gap, or first rotate axle 10 with second rotate axle 20 axial line be not subject to radial force at same straight line time, relative the second half oldham couplings 2 of the first half oldham couplings 1 can linearly move radially by groove 12, and then this radial force is cushioned, the first half oldham couplings 1 and the second half oldham couplings 2 are avoided to cause damage because being subject to bigger radial force, this oldham coupling, between Hard link and between being flexible coupling, the machinery damage that Deviation of equipments causes can be made to be preferably minimized degree, first rotates axle 10 and second rotates stable transmission between axle 20, improve integral device operational efficiency.
This utility model oldham coupling, for making the first rotation axle 10 and second rotate between axle 20 transmission stress evenly, preferably, straight line conduit 12 centrage is through the first through hole 11 axial line, and straight line conduit 12 is divided into the first half line conduit 121 and the second half line conduit 122 by the first through hole 11. This oldham coupling, the shape of straight line conduit 12 cross section can rectangle, trapezoidal.
