Abstract
The utility model relates to a universal connecting shaft unlikely to be damaged, which belongs to the technical field of connecting shafts, aims to improve the strength of connecting shaft components and transfer greater torque, and is unlikely to be damaged, thus the whole service cycle of the connecting shaft is prolonged. According to the technical scheme, the two ends of a connecting shaft stretch into a left joint and a right joint on the two sides respectively, the two ends of the connecting shaft are connected with the left joint and the right joint in a hinged manner through a sliding block, a pin and a bushing respectively, connecting holes connected with the pins are formed in flat heads at the two ends of the connecting shaft, the circumferences of the connecting holes are surrounded and closed by flat head bodies; the bore diameters of the connecting holes are matched with the outer diameter of the pins; the axes of the connecting holes are vertical to the plane of the flat heads. According to the universal connecting shaft, the flat heads of the connecting shaft of the universal connecting shaft become sealing structures of the connecting holes from an opening structure, so that weak links of the flat heads of the connecting shaft are compensated, the strength of the flat heads of the connecting shaft is strengthened, the deformation and cracking where the pins are installed at the flat heads of the connecting shaft are prevented, the using stability of the connecting shaft is improved, the whole sliding block type universal connecting shaft can transfer grater torque, and the service cycle is prolonged.
Description
Technical field
The utility model relates to a kind of slide block type universal connecting shaft, belongs to coupling shaft technical field.
Background technique
Universal connecting shaft is the driving parts for the moment of torsion of motor output is passed to operation mechanism by herringbone gear, can under heavy load, carry out the large distance of two between centers transmits due to universal connecting shaft, and two between centers have the moment of torsion of certain angular displacement, thereby there is higher flexibility and adaptability.
The composition of universal connecting shaft comprises the critical pieces such as spindle, left and right sides joint, lining, pin, slide block, the two ends of universal connecting shaft are stretched into by the homalocephalus of spindle in the joint of both sides, be hinged together by slide block, pin, lining and axis body, for the ease of the installation of pin, the structure that homalocephalus is installed pin place is opening, and opening can insert from the side of pin.According to long-term follow with record the fault that slide block type universal connecting shaft in use occurs, find that fault concentrates on the spindle parts of coupling shaft mostly, the damage type of spindle with the homalocephalus of spindle the distortion of pin place is installed, ftracture in the majority.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of non-damageable universal connecting shaft, and the spindle strength of parts of this coupling shaft is higher, can transmit larger moment of torsion, not fragile, thereby extends whole coupling shaft life cycle.
The technological scheme addressing the above problem is:
A kind of non-damageable universal connecting shaft, it comprises spindle, left joint, right connector, lining, pin, slide block, the two ends of spindle are stretched into respectively in the left joint, right connector of both sides, the two ends of spindle are articulated and connected by slide block, pin, lining and left joint, right connector respectively, its improvements are, on the homalocephalus at spindle two ends, have the attachment hole being connected with pin, attachment hole circumference by homalocephalus body around sealing.
Above-mentioned non-damageable universal connecting shaft, the aperture of described attachment hole and the external diameter of pin match, and attachment hole axis is vertical with homalocephalus plane.
The beneficial effects of the utility model are:
The utility model is changed into the spade half coupling place of universal connecting shaft the enclosed construction of attachment hole by hatch frame, make up the weak link of spade half coupling, greatly strengthen the intensity of spade half coupling, avoid spade half coupling that distortion, the cracking at pin place are installed, improve the stability in use of spindle, thereby make whole slide block type universal connecting shaft can transmit larger moment of torsion, and extend life cycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of spindle.
In figure, mark is as follows: left joint 1, right connector 2, slide block 3, lining 4, pin 5, spindle 6, attachment hole 7.
Embodiment
The utility model is in use flimsy homalocephalus of spindle, and the structural type by changing homalocephalus place is to reach the object that improves homalocephalus intensity.
In figure, show, the utility model comprises spindle 6, left joint 1, right connector 2, lining 4, pin 5, slide block 3.
The two ends of spindle 6 are stretched into respectively in the left joint 1, right connector 2 of both sides, and the homalocephalus at spindle 6 two ends is articulated and connected with left joint 1, right connector 2 by slide block 3, pin 5, lining 4 respectively.The joint of the homalocephalus of spindle 6 changes attachment hole structure into by original hatch frame, has made up the weak link of spindle 6 homalocephalus, has greatly strengthened the intensity of spindle 6 homalocephalus, has avoided spindle 6 homalocephalus that distortion, the cracking at pin 5 places are installed.
In figure, show there is the attachment hole 7 being connected with pin 5 on the homalocephalus at spindle 6 two ends point, attachment hole 7 circumference by homalocephalus body around sealing.The external diameter of the aperture of attachment hole 7 and pin 5 matches, and attachment hole 7 axis are vertical with homalocephalus plane.Pin 5 is inserted in attachment hole 7, by hinged by slide block 3, lining 4 to the two ends homalocephalus of spindle 6 and left joint 1, right connector 2, thereby realizes the effect of transmitting torque.The improvement at homalocephalus installation pin place does not affect the mounting type of universal connecting shaft, is guaranteeing, on the basis of original hinged flexibility, greatly to have strengthened the intensity of hinged place homalocephalus.
