Description

Drive elastic coupling flexible coupling

Technical field:

The utility model is a kind of driving elastic coupling flexible coupling, is mainly used in the precision instrumentation of electromechanical integration.

Background technique:

Coupling is mechanically operated common components.Be mainly used to connect driving shaft and driven shaft, with the intermediate member of transmitting movement and torque.But in the controlling mechanism of some electromechanical control translations, formerly the coupling in the technology can only play interconnect function, and can not move forward by driver part, and therefore formerly the coupling of technology just can't use separately in electromechanical integration.

Summary of the invention:

The utility model is in order to overcome the deficiency of technology formerly, to provide a kind of and can have the connection effect, can playing the coupling of motor driving translation again.

The utility model drives structure such as Fig. 1, Fig. 2, shown in Figure 3 of elastic coupling flexible coupling.Comprise the connecting shaft body 5 that has big end 8 and small end 9, on shaft coupling body 5 small ends 9 center side walls, there are 3 to be 120 ° of uniform stationary axle that supply connected body and the screw 2 that shaft coupling body 5 is fixed together respectively by the center line space, on the big end 8 of shaft coupling body 5, by shaft coupling body 5 big ends 8 positions that are connected with small end 9 n＞2 a big semicircle annular through groove 3 is arranged, the top of groove 3 and end all have through hole 4, there is gain 6 both sides of shaft coupling body 5 big ends 8, along the small end 9 central axis OO ' of shaft coupling body 5 vertically on have the stationary axle for connected body to insert fixed shaft hole 1, central axis O ' O along the big end 8 of shaft coupling body 5 " vertically on have the shifting axle for connected body to insert mobile axis hole 7; the central axis OO ' of fixed shaft hole 1 and the central axis O ' O of mobile axis hole 7 " on same straight line, and overlap with the central axis OO of shaft coupling body 5.Groove 3 is formed by the line cutting process, and line cutting fluting direction quadrature makes it have certain elasticity, so groove 3 not only can compensate the relative displacement of X, Y, Z axle, and the function of buffering and vibration damping is arranged.The quantity n of groove 3 is by big end 8 outer diameter D 2 and 2 decisions of big end 8 length L of shaft coupling body 5.The through hole 4 at groove 3 two ends also is that the line cutting process forms, and it is evenly distributed on the shaft coupling body 5 stress.Fixed shaft hole 1, mobile axis hole 7 are for being connected in the stationary axle of connected body and the shifting axle insertion shaft coupling body 5.Gain 6 is to move the mobile axis hole 7 of shaft coupling body 5 in and processing for the connected body shifting axle, and the length L 1 of gain 6 is the distance decisions of being moved by the connected body shifting axle, and the width B of gain 6 is to be determined by the rigidity that connects shifting axle.Shaft coupling body 5 adopts tin-phosphor bronze wear-resisting, good processability, perhaps No. 65 manganese steel (65Mn), perhaps the high elasticity steel processes, and does corresponding surface treatment after the processing.

The utility model orders about the process that shifting axle moves forward: the connected body motor rotation axis is inserted in the fixed shaft hole 1 of shaft coupling body 5 small ends 9, respectively with being screwed into three screws in 3 screws 2 on shaft coupling body 5 small ends 9 sidewalls, the motor rotation axis and the shaft coupling body 5 of connected body is fixed together after the reeve; One end of connected body shifting axle (diameter is littler than mobile axis hole) has pin hole, and the diameter of pin hole is consistent with gain 6 width B on the shaft coupling body 5, and the other end car of connected body shifting axle has outside thread.The shifting axle that will have pin hole one end is inserted in the mobile axis hole 7 of shaft coupling body 5 big ends 8, pin is by behind the gain 6 of shaft coupling body 5 one sides, pass the pin hole on the connected body shifting axle of putting into mobile axis hole 7, pass the gain 6 of shaft coupling body 5 opposite sides again, pin and gain 6 Spielpassung make the pin can be along moving in the gain 6; Pin be connected pin hole drive fit on the shifting axle, make pin be unlikely to come off, thereby connected shifting axle and shaft coupling body 5 linked together from the connected body shifting axle.Outside thread one end of connected body shifting axle has nut, and nut is fixed on other parts.When the motor of connected body rotates, drive and drive the coupling rotation, pin passes to rotation and is connected shifting axle, therefore the connected body shifting axle also and then rotates, because connected body moves the nut of axle head and fixes, make that being connected shifting axle also moves forward when rotating, thereby realize that motor driving connected body shifting axle moves forward.

Compare the utility model with shaft joint in the first technology: with simple structure, not only play the effect of connection, also finished the action of translation simultaneously.Utilize screw pair rotation can be converted into the characteristic of translation, realized function, possess the function of elastic coupling flexible coupling simultaneously, compensation space relative displacement well, and function with buffering and vibration damping by the motor driving translation.The utility model has been used for the actual machine transmission, has proved that fully it has good use value.
