Abstract

A cross shaft universal coupling comprises a driving fork connector, a driven fork connector and a cross pin, wherein the driving fork connector and the driven fork connector are connected together through the cross pin; the cross pin comprises a first main body for the cross pin, a second main body for the cross pin, a first shaft and a second shaft; a first shaft upper semi-circular groove and a second shaft upper semi-circular groove which accommodate the first shaft and the second shaft respectively and are perpendicular to each other are formed on the first main body for the cross pin; a first shaft lower semi-circular groove and a second shaft lower semi-circular groove which accommodate the first shaft and the second shaft respectively and perpendicular to each other are formed on the second main body for the cross pin; a first notch is formed at the middle part of the first shaft; a second notch is formed at the middle part of the second shaft; the first notch is fastened and complemented with the second notch; and the first main body is fixedly connected with the second main body through a screw rod. The utility model has the advantages that the disassembly is convenient, that is, when the cross shaft universal coupling needs to be disassembled, the first main body and the second main body can be separated only by loosing the screw rod.

Description

A kind of cross-axle universal shaft coupling

Technical field

The utility model relates to the improvement to cross-axle universal shaft coupling.

Background technique

Hooks coupling universal coupling is that two axles (driving shaft and driven shaft) that are used for connecting in the different institutions make it the mechanical parts of common rotation with transmitting torque.Hooks coupling universal coupling utilizes the characteristics of its mechanism, makes diaxon not at same axis, exist under the situation of axis angle to realize that the diaxon that is connected turns round continuously, and transmitting torque and motion reliably.The characteristics of Hooks coupling universal coupling maximum are to have bigger angular compensatory ability, compact structure, transmission efficiency height.Hooks coupling universal coupling divides from its structure can be divided into Cardon universal joint, Rzeppa type and curved grooved type etc., common universal coupling with spider as shown in Figure 6, it comprises initiatively knuckle joint 10 and passive knuckle joint 11 and cross pin 12, and described active knuckle joint 10 and passive knuckle joint 11 link together both by cross pin 12.The cross pin of existing cross-axle universal shaft coupling all is the method single forming with casting, after cutting, make cross pin, with the made coupling of this cross pin, any one parts damages when coupling, when needing to change this coupling, inconvenient completely, after the cross pin destruction with coupling, just can unload whole coupling earlier.

Summary of the invention

The technical problem that the utility model solves is: the cross-axle universal shaft coupling that a kind of convenient disassembly is provided.

The technical solution of the utility model is: a kind of cross-axle universal shaft coupling is provided, comprise initiatively knuckle joint and passive knuckle joint and cross pin, described active knuckle joint and passive knuckle joint link together both by cross pin, described cross pin comprises cross pin first main body, second cross pin main body, first and second, be provided with first upper half-round slot and second upper half-round slot of respectively ccontaining first and second on described cross pin first main body, described first upper half-round slot is vertical mutually with second upper half-round slot; On described second cross pin main body, be provided with ccontaining second respectively first second circular groove and second second circular groove, described first second circular groove is vertical mutually with second second circular groove, be provided with first gap at described first middle part, be provided with second gap at described second middle part, described first gap is relative with second gap to fasten, and complementary, described first main body is fixedlyed connected by screw rod with second main body.

Described first main body and second main body are rectangle, circle or polygonal.

The diameter that the width of described first gap equals second, the radius that the height of first gap equals first; The diameter that the width of described second gap equals first, the radius that the height of second gap equals second.

Described first and second equal diameters.

Described first gap and the second gap equal and opposite in direction.

The utlity model has the advantage of convenient disassembly, when needing dismounting, only need unclamp screw rod, first main body and second main body are separated, just coupling can be separated.

Embodiment

Below in conjunction with accompanying drawing, explain in more detail originally bright.

See also Fig. 1 to Fig. 5, what it disclosed is a kind of cross-axle universal shaft coupling, comprise initiatively knuckle joint 6 and passive knuckle joint 7 and cross pin, described active knuckle joint 6 is connected with first 3 by first hole 61, described passive knuckle joint 7 is connected with second 4 by second hole 71, described cross pin comprises cross pin first main body 1, second cross pin main body 2, first main body 1 of cross pin described in the present embodiment and second cross pin main body 2 are square, obviously, cross pin first main body 1 and second cross pin main body 2 can be circle or Else Rule geometrical shape, first 3 and second 4, be provided with first upper half-round slot 11 and second upper half-round slot 12 of ccontaining first 3 and second 4 respectively on described cross pin first main body 1, described first upper half-round slot 11 is vertical mutually with second upper half-round slot 12; On described second cross pin main body, be provided with ccontaining second respectively first second circular groove 21 and second second circular groove 22, described first second circular groove 21 is vertical mutually with second second circular groove 22, be provided with first gap 31 at described first 3 middle part, be provided with second gap 41 at described second 4 middle part, described first gap 31 and second gap, 41 relative fastenings, and complementary, described first main body 1 and second main body 2 are respectively equipped with four screws 13, and be fixedly connected by four screw rods 5.

In the present embodiment, described first 3 and second 4 equal diameters, and first gap 31 and second gap, 41 equal and opposite in directions.

Obviously, first 3 and second 4 diameter in the utility model can be unequal, at this moment, as long as satisfy the diameter that the width of first gap 31 equals second 4, the radius that the height of first gap 31 equals first 3; The diameter that the width of described second gap 41 equals first 3, the condition that the height of second gap 41 equals second 4 radius gets final product.
