Description

Technical Field

[0001] The utility model relates to the technical field of trunnions, in particular to an adaptive trunnion. Background Art

[0002] A trunnion is a pivot or spindle mounted on a support for rotating or tilting something, or a crosshead pin on which a connecting rod rotates.

[0003] At present, ear shafts are widely used as a component that facilitates the rotation or tilting installation of objects. Traditional ear shafts are mostly one-piece structures. One ear shaft can only be used for one type of shaft, and the installation position of some objects is easily restricted by the installation surface or space. For such cases, it is often necessary to select a special ear shaft that is suitable for the object to be installed. This leads to a decrease in the adaptability of the ear shaft and is not convenient to meet the installation requirements of objects in different situations. In view of this, we propose an adaptive ear shaft. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By providing a sleeve ring, a connecting plate, an annular plate, a V-shaped slot, an ear shaft sleeve and a V-shaped plug, and by installing the annular plate and the ear shaft sleeve in a detachable form, it can be adapted to shafts of various sizes for use, and the V-shaped plug and the V-shaped slot are both designed as a V-shaped structure, which can limit the movement of the ear shaft sleeve in the radial direction, so that the connection between the ear shaft sleeve and the annular plate is more stable, and the V-shaped structure has a more stable supporting effect.
