Abstract
The utility model discloses a coupling, which comprises a driving shaft and a driven shaft, wherein a flange is respectively arranged on the driving shaft and the driven shaft, and a slot is arranged on one of the flanges, and a convex post is arranged on the other flange; the convex post of which the diameter is matched with the slot extends into the slot. The utility model which has a low requirement for the installation accuracy can also work when the two shafts are deflected.
Description
Technical field
The utility model belongs to mechanical field, specifically, relates to a kind of coupling.
Background technique
Coupling is a kind of link very common in the mechanical field, is used to transmit two rotations between the axle, general coupling, and flexible loop pillar pin coupling, rod pin coupling, double strand chain coupling etc. are multiple.These coupling have individual shortcoming, exactly the accuracy of axle are had relatively high expectations, if two axles not on same straight line, just are difficult to realize transmission.And in real work, because reasons such as transportation vibrations, installation environments, driving shaft and driven shaft depart from probably, also have bigger departing from sometimes, therefore need the lower coupling of a kind of required precision.
Summary of the invention
To be solved in the utility model be coupling to the too high problem of installation requirement, provide a kind of required precision low, the convenient coupling of installing.
For this reason, the technical solution adopted in the utility model is such: coupling, comprise a driving shaft and a driven shaft, respectively have a flange on driving shaft and the driven shaft, it is characterized in that: one of them flange is provided with a groove, another flange is provided with a projection, and this projection diameter matches with described groove, and stretches in this groove.
Further, between described projection and the flange for being rotationally connected.
Further, described projection cross section is a square, and this foursquare length of side matches with groove on another flange.
In the utility model, be that cooperation by projection and groove comes transmitting movement between two flanges, and projection can be done slip to a certain degree in groove, like this when two axles have position deflection, the position of projection in groove was constantly to change during flange rotated, promptly slide, offset the skew of axle like this, all can make driven shaft follow driving shaft under any phase place and rotate along groove; Adopt square projection, can strengthen the surface of contact with groove, make the transmission better effects if.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2, Fig. 3 are respectively the structural representations of two flanges.
Embodiment
In the present embodiment, 1 is driving shaft, and 2 is driven shaft, and in fact both also can exchange; Have flange 3 on the axle 1, have flange 4 on the axle 2; Have groove 5 on the flange 4, have square projection 6 on the flange 3, be rotationally connected by pin 7 and flange 3; The length of side of projection 6 matches with the width of groove 5, in the card entry slot 5, slides in groove 5, and promote flange 4 rotations when axle 1 rotates, and then axle 2 is rotated, and reaches the purpose of transmitting movement.
Claims (3)
1. coupling comprises a driving shaft and a driven shaft, respectively has a flange on driving shaft and the driven shaft, it is characterized in that: one of them flange is provided with a groove, another flange is provided with a projection, and this projection diameter matches with described groove, and stretches in this groove.
2. coupling as claimed in claim 1 is characterized in that: between described projection and the flange for being rotationally connected.
