fig. 2 is an explosion diagram of the universal shaft for rubber processing equipment in the embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-2, the present invention provides a universal shaft for rubber processing equipment, which includes a connecting shaft 10, a connecting seat 20, a cross 30 and a fastening member 40.
The both sides of connecting seat 20 set up lug 21, and lug 21 lays relatively, sets up connecting hole 22 on the lug 21, and the tip of connecting seat 20 sets up connecting hole 22, sets up fixed screw hole 23 on the outer wall of connecting hole 22, and a plurality of fixed screw hole 23 set up along the circumferencial direction interval of connecting hole 22, specifically, four fixed screw hole 23 evenly set up along the circumferencial direction of connecting hole 22.
The two connecting seats 20 are vertically crossed, the shaft ends of the cross shaft 30 are respectively connected with the lifting lugs 21 of the two connecting seats 20, wherein the shaft ends of the cross shaft 30 are connected with the connecting holes 22, and the cross shaft 30 realizes power transmission between the two connecting seats 20.
The end of the connecting shaft 10 is provided with a stepped groove 11, and the stepped groove 11 is recessed along the radial direction of the connecting shaft 10, thereby forming an accommodating space for accommodating the end of the fastening member 40.
One end of the connecting shaft 10, which is far away from the stepped groove 11, is provided with a key groove 12 to realize connection with other components.
The connecting shaft 10 is connected in the connecting hole 22, the fastening piece 40 is connected in the fixing threaded hole 23, the end part of the fastening piece 40 is accommodated in the stepped groove 11, the fastening piece 40 is matched with the stepped groove 11 to limit the connecting shaft 10 to move along the axis direction of the connecting shaft, and furthermore, the end part of the fastening piece 40 is in interference fit with the stepped groove 11, so that the transmission of power can be realized while the limit is realized.
The end of the fixing threaded hole 23 is provided with a nut 41, the nut 41 is attached to the outer wall surface of the connecting seat 20, and the outer diameter of the nut 41 is larger than the inner diameter of the fixing threaded hole 23.
The fixing threaded holes 23 are formed in the connecting base 20 in the circumferential direction to assemble the connecting fasteners 40, the stepped grooves 11 for accommodating the ends of the fasteners 40 are formed in the shaft ends of the connecting shaft 10 to limit the movement of the connecting shaft 10 in the axial direction thereof, the connecting shaft 10 and the connecting base 20 are connected by clamping the fasteners 40 in the circumferential direction, the fastening clamping performance of the shaft ends in the circumferential direction is improved, and the connection stability between the connecting shaft 10 and the universal shaft is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
