Abstract
The utility model discloses a connection part for connecting workpieces, in particular to a trunnion. A conventional trunnion is cast integrally in general, one trunnion is suitable for one type of shafts only, a general connection part suitable for various shafts cannot be formed, the use range is small, and limitation is large; in addition, an enterprise uses corresponding trunnions for shafts in different outer circumference shapes, so that production cost of the enterprise is increased. The trunnion is composed of rotating portions and connection portions, a rotating shaft is arranged on the outer wall of each rotating portion, the connection portions are connected to the rotating portions in a fastened mode, and the inner wall of each connection portion is an arc surface or a plane. The trunnion is detachable, capable of being used selectively according to the different outer circumference shapes of the shafts which are used, and suitable for the shafts which have the round or arc outer circumference and conduct direct movement. Besides, the rotating portions and the connection portions are replaceable, so that maintenance cost and use cost are reduced.
Description
Technical field
The utility model relate to a kind of connect workpiece link, refer in particular to a kind of gudgeon.
Background technique
The general cast inblock of existing gudgeon, a gudgeon can only be applicable to a class axle part and use, and can't form the Universal connecting piece of all kinds of axle parts, and using scope is little, and limitation is large; In addition, enterprise is used its corresponding gudgeon at the axle part to different outer circumferential shape, has increased the cost of production of enterprise.
The model utility content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, and it is a kind of simple in structure that the spy provides, the gudgeon that different axle parts is used applicable to excircle.
Two, technological scheme
For solving the problems of the technologies described above, the utility model gudgeon, wherein, be comprised of rotation section and joint, and above-mentioned rotation section outer wall is provided with rotatingshaft, and above-mentioned joint and rotation section are fastenedly connected, curved of the inwall of above-mentioned joint or plane.
The two ends of above-mentioned joint are provided with and coordinate projection, above-mentioned projection and the rotation section interference fit of pegging graft with rotation section.
Three, the beneficial effects of the utility model
The utility model gudgeon is a kind of detachable gudgeon, can carry out choice for use according to the difference of using axle part outer circumferential shape, the utility model gudgeon is the axle part use that circle or arc have craspedodrome concurrently applicable to excircle, and, rotation section and joint are all replaceable, reduce maintenance cost and user cost.
The accompanying drawing explanation
Fig. 1 is the utility model gudgeon plan view one;
Fig. 2 is the utility model gudgeon plan view two;
