Abstract
The utility model proposes a kind of universal joint, solved the pin frangibility of universal joint in prior art, and the defect of easily wearing and tearing.It comprises connecting rod and pin, and described connecting rod two ends are respectively equipped with the first position, hole and the second position, hole, and described the first position, hole and described the second position, hole have all been bumped into anti-wearing liner; Described the first position, hole is mutually vertical with described the second position, hole.The utility model is simple in structure, and twisting resistance increases, and transient starting is difficult for making pin to twist off, its long service life.
Description
Technical field
The utility model relates to a kind of universal joint, particularly a kind of vertical-type pin formula universal joint.
Background technique
Universal joint is mounted in the connection set between screw pump output shaft and screw pump rotor.
Present conventional horizontal pin formula universal joint 1A, as shown in Figure 1, its connecting rod 2A two ends are respectively equipped with the universal hole position 3A being parallel to each other, and it because universal hole position 3A easily produces and fractures pin on same line, and easily weares and teares when transient starting.
Therefore be necessary to design a new universal joint, make up above-mentioned defect.
Model utility content
The utility model proposes a kind of universal joint, solved the pin frangibility of universal joint in prior art, and the defect of easily wearing and tearing.The utility model is simple in structure, and twisting resistance increases, and transient starting is difficult for making pin to twist off, its long service life.
The technical solution of the utility model is achieved in that
A universal joint, it comprises connecting rod and pin, and described connecting rod two ends are respectively equipped with the first position, hole and the second position, hole, and described the first position, hole and described the second position, hole have all been bumped into anti-wearing liner; Described the first position, hole is mutually vertical with described the second position, hole.
Further, described first central axis of position, hole and the upper-end surface of described connecting rod are vertical; Described second central axis of position, hole and the upper-end surface of described connecting rod are parallel.
The utility model is, on the basis of former horizontal type pin formula universal joint, Vertical direction is made into in two positions, hole of original one-tenth substantially horizontal, therefore the utility model twisting resistance increases, transient starting is difficult for making pin to twist off, and improves universal joint working life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of prior art universal joint;
Fig. 2 is the structural representation of the utility model universal joint.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 2, a kind of universal joint 1, it comprises connecting rod 2 and pin 3, and described connecting rod 2 two ends are respectively equipped with the first position, hole 21 and the second position, hole 22, and described the first position, hole 21 and described the second position, hole 22 have all been bumped into anti-wearing liner 4; Described the first position, hole 21 is mutually vertical with described the second position, hole 22.The setting of the utility model anti-wearing liner, when connecting rod two ends are stressed, pin all produces friction with the inwall of the first position, hole, the second position, hole, therefore anti-wearing liner all plays a protective role to pin, the first position, hole and the second position, hole, reduces its wearing and tearing.And in the utility model, anti-wearing liner is done corresponding adjustment according to the shape of the first position, hole and the second position, hole.
Further, the central axis of described the first position, hole 21 is vertical with the upper-end surface of described connecting rod 2; The central axis of described the second position, hole 22 is parallel with the upper-end surface of described connecting rod 2.
The utility model universal joint in use, is inserted into the first position, hole and the second position, hole by pin, thereby screw pump output shaft and screw pump rotor is connected to the two ends of universal joint; When screw pump output shaft and screw pump rotor move simultaneously, connecting rod two ends are all stressed, because the first position, hole is mutually vertical with the second position, hole, therefore the application of force direction of screw pump output shaft and screw pump rotor is mutually vertical, thereby make the force direction that is subject at connecting rod two ends become 90 degree, and hunting range is large, thereby difficult generation of pin fracture, and wearing-in period can extend, further extended the working life of universal joint.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
