The existing rotating shaft is usually directly connected to the support through a fixing device, and the fixing device cannot provide certain limiting buffering effect outside the supporting and fixing effect. The spherical structure commonly adopted at present is used for buffering the rotating shaft. However, the existing spherical structure consumes too much material and has too heavy volume on one hand, and the contact surface between the spherical structure and the fixed supporting device is too large, so that excessive abrasion is caused. There is still a need for an improved solution for a spherical structure and a fixed support device for cooperating with the spherical structure.

Preferably, the center of the spherical structure is matched with the end of the rotating shaft only.
Preferably, the spherical structure is made of engineering plastics.
The fixing and supporting device based on the spherical structure with the groove comprises a fixing and supporting device and a spherical structure, wherein the spherical structure is fixed on a bracket through the fixing and supporting device surrounding the upper end and the lower end of the spherical structure; the fixed supporting device consists of an upper part and a lower part, and each part is of an arch structure; the outer surface of the spherical structure is in contact with the inner surface of the dome.
Preferably, when the rotating shaft rotates, the spherical structure does not rotate synchronously with the rotating shaft; when the rotating shaft deflects, the spherical structure deflects with a certain angle along with the rotating shaft, and the position of the fixed supporting device outside the spherical structure is always unchanged.
The invention has the beneficial effects that: according to the spherical structure with the grooves and the fixing and supporting device thereof, the outer surface of the spherical structure is not completely smooth, and the grooves are arranged on the spherical structure, so that the friction between the spherical structure and the fixing and supporting device can be reduced, and the cost of the spherical structure can be reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
as shown in fig. 1 to 3, the spherical structure and the fixing and supporting device 5 thereof according to the present invention comprise a fixing and supporting device 5 and a spherical structure, wherein a rotating shaft 4 is inserted into a center 3 of the spherical structure, and the spherical structure is fixed on a bracket by the fixing and supporting device 5 surrounding upper and lower ends of the spherical structure; the fixed supporting device 5 consists of an upper part and a lower part, each part is of an arch structure, and the outer surface 1 of the spherical structure is in contact with the inner surface of the arch structure; the outer surface 1 of the spherical structure is provided with a plurality of grooves 2.
The fixed support means 5 are not directly connected to the rotating shaft 4 but indirectly connected through a spherical structure. The spherical structure is connected with the rotating shaft 4, certain buffering, limiting and deviation rectifying effects are achieved on the rotating shaft 4, and the spherical structure is fixed with the frame body through the fixing and supporting device 5.
The invention is different from the prior art in that: the outer surface 1 of the spherical structure is not completely smooth and is provided with a plurality of grooves 2. The function of the groove 2 is: on the one hand, the friction between the spherical structure and the fixed support 5 can be reduced, and on the other hand, the cost of the spherical structure can be reduced. In addition, the groove 2 can contain lubricating lubricant for assisting rotation.
The using process of the invention is as follows: based on the spherical structure with the groove and the fixed supporting device 5 thereof, the end part of the rotating shaft 4 passes through the center 3 of the spherical structure, and the outer surface 1 of the spherical structure is contacted with the fixed supporting device 5. When the rotating shaft 4 rotates, the spherical structure does not synchronously rotate along with the rotating shaft 4; when the rotating shaft 4 deflects, the spherical structure deflects with a certain angle along with the rotating shaft 4, and the fixed supporting device 5 outside the spherical structure is always unchanged in position.
Example 2:
as shown in fig. 1 to 2, the grooves 2 are located on the outer surface 1 of the spherical structure, and at least two grooves 2 are provided on the spherical structure. The opening direction of the groove 2 is parallel to the central line of the center 3 of the spherical structure.
It should be noted that: the shape of the groove 2 on the spherical structure is various and can be set according to requirements. The groove 2 shown in fig. 1 is a right-angle groove, and can also be a trapezoidal groove, a triangular groove, an arc groove, etc.
The opening directions of the grooves 2 on the spherical structure are also various and can be set according to requirements. The direction shown in fig. 1 is parallel to the center line, and may be perpendicular to the center line or inclined at a certain angle.
The depth of the groove 2 on the spherical structure is determined by the material and diameter of the spherical structure. Usually, the spherical structure is made of engineering plastics, and the depth of the groove 2 is not more than half of the radius.
The invention can be widely applied to the occasions of fixing devices.
It is well within the skill of those in the art to implement and protect the present invention without undue experimentation and without undue experimentation that the present invention is directed to software and process improvements.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
