Description
Technical field
The utility model relates to the quick transmission joint between a kind of axle, belongs to field of mechanical technique.
Technical background
Current connection between axle and axle is machine power drive mechanism emphasis to be solved and difficult point always, it is quick, stable in the hope of the connection that reaches between the axle that people have found out multiple linkage structure, effects such as driving torque is big, coaxality height, the endoporus that has proposed a kind of motor shaft sleeve as Chinese patent 96229752.6 is one to be the die cavity of I-shaped slotted eye, in-built electrical arbor, elastic metal sheet and elastomer, elastomer is provided with two, be separately positioned on two sides of die cavity inwall, elastic metal sheet also is provided with two, then is covered in elastomeric surface respectively.Motor shaft is inserted in this effect that had not only had the transmission agency of common key but also had vibration and noise reducing in the die cavity center of motor shaft sleeve, can be widely used in the driving mechanism of electric vehicle motor axle and other motor shafts.Chinese patent CN200420114864.8 discloses a kind of stiff shaft linkage structure of water pump spindle, comprise pump shaft, live axle, it is characterized in that: there is counterbore at the place, axle center of pump shaft, one vertically slit is arranged on a side of pump shaft, the slit connects to interior counterbore, in interior counterbore live axle is arranged, and a locking ring is arranged outside pump shaft, locking ring is a C font, and its two ends have lock screw to connect.The advantage of this structure is to improve pump shaft and the rigidly connected reliability of live axle, installation and dismounting between the convenient simultaneously axle.But the dismounting of said structure and install still comparatively complicatedly, fixedly the technological scheme of diaxon is comparatively complicated for it.
Summary of the invention
The utility model purpose is to provide a kind of device of quick connection transmission shaft, has solved the installation that prior art exists, dismounting complexity and the fixing comparatively complicated problems of axle.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of quick connection transmission device, comprise plug-in part, outer sleeve body, plug-in part is that coaxial insertion is connected with outer sleeve body, it is characterized in that described outer sleeve body is provided with movable positive stop key, movable positive stop key is axially vertical substantially with plug-in part, the limited part that cooperates with movable positive stop key is arranged on the described outer sleeve body, described outer sleeve body is provided with the torque drive key, and described plug-in part is provided with the driving hole that cooperates with the torque drive key.Insert in the outer sleeve body as a kind of quick connection transmission device plug-in part, usually the surface of contact of plug-in part and outer sleeve body is the cylndrical surface, the coaxality of diaxon can be greatly improved like this, when not having other limit stoper, diaxon has orthogonal two degrees of freedom after assembling, cooperation by movable positive stop key and limited part, make diaxon fixing in the axial direction, they can only radially rotate on the cylndrical surface, and it also can be to open that the activity of movable positive stop key makes positive stop key and limited part can make locking.Pin movable positive stop key plug-in part is inserted in the outer sleeve body, the state locking plug-in part of change activity positive stop key and endwisely slipping of outer sleeve body.The torque drive key is set on outer sleeve body, and the hole slot that is provided with on it and the plug-in part cooperates can lock radially sliding of plug-in part and outer sleeve body, and moment of torsion is provided in transmission.Certainly the torque drive key also can be arranged on the plug-in part, and this is equal to.
As preferably, described movable positive stop key is that cylindrical body and it are provided with the arcuation grooving, and the interior circular arc of movable positive stop key and outer sleeve body intersects, and described limited part is annular arc groove shape.Movable positive stop key be located at outer sleeve body in the circle position of intersecting, the circular arc grooving of positive stop key is in the interior circular arc of outer sleeve body when positive stop key is compacted, plug-in part is inserted in the outer sleeve body, change the positive stop key position, the non-slot portion of positive stop key is in the interior circular arc of outer sleeve body, and positive stop key in being in the circular arc and limited part cooperate endwisely slipping of plug-in part and outer sleeve body is fixing.Because the torque drive pin will radially slide locking, transmission is effectively stablized simultaneously, and its assembling simultaneously and dismounting are all very convenient.
As preferably, described movable positive stop key links to each other with Returnning spring.Returnning spring is arranged on the end of movable positive stop key, and its other end links to each other with outer sleeve body, and after plug-in part and outer sleeve body assemble, thereby Returnning spring makes positive stop key return locking plug-in part like a cork.
As preferably, described movable positive stop key is axially arranged with keyway, is provided with in outer sleeve body and the corresponding position limit pin of keyway.The end of position limit pin slide relative in keyway all the time when movable positive stop key is movable, position limit pin blocks movable positive stop key after assembling is finished, and prevents its ejection.
As preferably, described movable positive stop key is a cylinder, and movable positive stop key and outer sleeve body intersect, and described limited part is the hole slot that is arranged on the plug-in part.These are different with tangent situation, and positive stop key directly inserts on the slotted eye that is arranged on the plug-in part, directly by positive stop key locking plug-in part.
As preferably, described torque drive pin is the cylindrical body of two parallel symmetries, the parallel to an axis of they and plug-in part.The torque drive pin is arranged to cylinder type and is beneficial to when assembling and the hole slot cooperation, and its transmission alignment height when being symmetrical arranged is stressed even.
As preferably, described plug-in part end is provided with flat key, and described outer sleeve body end is provided with the arcuation key.The plug-in part end be provided with flat key and other axles when linking to each other chelating simpler, the outer sleeve body end is set to the circular arc key and cooperates with other, cooperation tightness height, transmission accurately is difficult for skidding, and assembles also comparatively simple.
Therefore, the utlity model has assembling, dismounting is simple fast, the coaxality height such as is widely used at characteristics.
