Background

A ten-joint cardan shaft is a mechanical element for transmitting rotational force, commonly used in transmission systems. It is composed of a cross-shaped structure, and each cross arm is provided with a joint for connecting other transmission components such as bearings, gears and the like. The cross joint universal shaft can rotate on a plurality of planes, so that power can be transmitted under the condition that the rotation directions are inconsistent.

The joint on the existing cross shaft is mainly realized by four equal cylindrical mounting shafts perpendicular to each other in pairs to hinge other components such as a conventional connecting rod, the conventional connecting rod is assembled by penetrating through a jack in order to be matched with the existing cross shaft, and the mounting shafts are inserted into the jack by the aid of the assembly mode through extremely large extrusion force, so that the extrusion force is completely covered in the assembly process, and meanwhile, the matched assembly of the aimed connecting components is realized by loading the jack on the connecting components, so that the applicability of the assembly is limited, and the assembly of the aimed connecting components cannot be realized.

Disclosure of Invention

The utility model aims at: based on the existing cross joint universal shaft, the synchronous loading can be realized by adopting a hybrid universal joint assembled by other modes and other assembly parts, so that the technical problem that the assembly of the existing cross joint universal shaft is limited is solved.

The mixed universal joint convenient to assemble comprises a central shaft and a connecting part fixed with the outer side of the central shaft, wherein the connecting part consists of four end faces protruding outwards along the upper, lower, left and right edges, and the connecting part between the connecting part and the central shaft is in arc connection; the method is characterized in that: the left and right opposite end surfaces are provided with first bearing bowls along the outer surfaces, the upper and lower opposite side surfaces are provided with bearing seats, and each bearing seat is provided with an assembly hole site.

Further, the bearing seat is provided in the shape of a vertical plate block, and the bearing seats at the upper end face and the lower end face are assembled on an arc-shaped connecting part with the central shaft thereof.

Further, the upper and lower opposite end surfaces are provided with a second bearing bowl along the outer periphery, and a gap is arranged between the second bearing bowl and the bearing seat at the side part.

Further, the four end faces are vertically arranged in pairs.

The beneficial effects of the utility model are as follows:

on the basis of the existing cross joint universal shaft, a bearing seat which is assembled by adopting an assembly hole and other components is loaded at the same time, and an adaptive assembly mode is added on the basis of not deviating from the original hinge component.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.

Detailed Description

The following description of the technical solutions in the embodiments of the present utility model will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the utility model comprises a central shaft 1 and a connecting part 2 fixed with the outer side of the central shaft 1, wherein the connecting part 2 consists of four end faces protruding from the upper, lower, left and right sides, and the connecting part 2 between the connecting part 2 and the central shaft 1 is in arc connection; the method is characterized in that: the left and right opposite end surfaces are provided with first bearing bowls 3 along the outer surfaces, the upper and lower opposite side surfaces are provided with bearing seats 4, and each bearing seat 4 is provided with an assembly hole site 5.

The central shaft 1 is provided with a connecting part 2 connected with the external assembly, the connecting part 2 consists of four opposite end faces which are vertical to each other up and down and left and right, and the four end faces of the existing cross joint universal shaft are connected with bearing bowls to match the external assembly.

Embodiment one: referring to fig. 1 and 2, on the basis of the prior art, the left and right opposite end surfaces of a central shaft 1 are provided with first bearing bowls 3 along the outside, two opposite side surfaces at the upper and lower end surfaces are provided with bearing seats 4, and the bearing seats 4 are provided with assembly holes 5, wherein the assembly holes are screw holes, screws, fixing pieces or other conventional manners for connecting external components. The assembly mode is simple, compared with the conventional mode that four identical bearing bowls are arranged outside the central shaft 1, the adopted mode is that the left end and the right end are provided with the first bearing bowls 3, the upper end and the lower end are provided with the bearing seats 4, namely the double-lug-hole mixed universal joint is formed, the assembly is realized by assembling corresponding assembly parts by adopting the conventional assembly hole sites 5 with wider applicability on the basis of matching components of the first bearing bowls 3 and jacks on the connecting rods, and the upper bearing bowls 4 and the lower bearing bowls.

Embodiment two: referring to fig. 3, in the first embodiment, the second bearing bowl 7 is arranged along the outer edge of the upper and lower opposite end surfaces, and for the bearing seat 4, the second bearing bowl 7 is assembled on the arc-shaped connecting part 6 connected between the central shaft 1 and the outer protruding end surface and is in the shape of a vertical plate block, so that a gap is left between the second bearing bowl 7 and the bearing seat 4, and the extending part penetrating the assembly hole site 5 does not contact the second bearing bowl 7, i.e. the assembled fixing piece in the assembly hole site 5 can conveniently collide with the second bearing bowl 7 from the outer edge to the inner edge, so that the assembled fixing piece cannot collide with the second bearing bowl 7, but adopts a certain dislocation space, and the assembly mode is simpler and easier. Meanwhile, the bearing seat 4 is assembled on the arc-shaped connecting part 6, so that the assembly of the joint part of the bearing bowl is not influenced.

The present utility model is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present utility model.
