Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the floating large-sized dry oil seal ring includes a seal ring body 1, a circular groove 2 is formed at the bottom of the seal ring body 1, a spring sleeve 3 is disposed inside the circular groove 2, and a spring 4 is sleeved inside the spring sleeve 3.
Further, cavity 5 has been seted up to the outer lane of sealing ring body 1, and first sphere 6 has been seted up to the outer lane of sealing ring body 1, through setting up cavity 5, can conveniently effectively store the butter.
Further, a second spherical surface 7 is arranged on the inner ring of the sealing ring body 1, and the sealing ring can be effectively matched with a body to be used through the second spherical surface 7.
Further, the outer sleeve of spring 4 is equipped with guide pin bushing 8, through setting up guide pin bushing 8, can effectively carry on spacingly to spring 4.
The working principle is as follows: the bowl-shaped tile is installed at the center of the bowl-shaped tile seat, the movable cone body is seated on the bowl-shaped tile, the lower spherical surface of the movable cone is matched with the upper spherical surface of the bowl-shaped tile, a bearing platform is machined on the periphery of the bowl-shaped tile frame, a circle of spring 4 is arranged on the circumference of the platform, a guide sleeve is installed, the sealing ring body 1 is integrally cast, after the whole machining, the sealing ring body is sleeved on an outer ring platform of the bowl-shaped tile seat, the sealing ring is supported and floated on the bowl-shaped tile seat by the aid of the matching of the spring 4 and the spring sleeve 3, the two layers of spherical surfaces of the sealing ring and the bottom spherical surface of the body are closely matched with the body by the aid of the elastic force of the elastic element, the body is in 3D.
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. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
