Abstract
The invention discloses a floating type fluid circulating passageway. The floating type fluid circulating passageway comprises two pipe connecting pieces and a floating ring, wherein the two pipe connecting pieces can rotate oppositely, the floating ring is located between the two pipe connecting pieces, a radial gap is reserved between the floating ring and one pipe connecting piece, and an elastic ring is installed in the radial gap so that sealing can be guaranteed; the floating ring is in clearance fit with the other pipe connecting piece, and a bearing is installed to guarantee that the floating ring and the pipe connecting piece are coaxial; the two pipe connecting pieces are provided with ducts used for conveying of fluid; a duct used for communicating the ducts on the two pipe connecting pieces is arranged on the floating ring. According to the floating type fluid circulating passageway, the elasticity and airtightness of the elastic ring and the rigidity of the bearing are utilized, required radial floating is achieved completely by the elastic ring, the sealing clearance between the floating ring which rotates oppositely and the pipe connecting pieces can be minimized according to machining precision, and in this way, the whole fluid circulating passageway has the advantages of being high in radial floating capacity, good in sealing performance, high in reliability, and free of abrasion.
Description
Technical field
The present invention relates to fluid passage design, the especially design of machinery industry lubricating oil path and oil circuit control.
Background technique
In Machine Design, often need fluid to transmit between two counterrotating parts, between two, need to adopt rotary seal, between rotary seal two parts, need to have higher coaxality and less gap so that path reaches required pressure and sealing requirements.But due to the existence of the factors such as machining error and stand under load distortion, between two parts, can produce bias, the seal clearance between two needs to be greater than this offset, and this will certainly reduce the sealing between two parts.
Summary of the invention
Object of the present invention is intended to overcome the deficiencies in the prior art, and a kind of floating type fluid turn passage that can allow larger radial floating amount can guarantee again better sealing is provided.
Object of the present invention can be achieved by the following technical measures:
This floating type fluid turn passage, comprise two counterrotating pipe connectors of need, a floating ring between described two pipe connectors, described two pipe connectors are equipped with the duct in order to Fluid Transport, and described floating ring is also provided with to link up the duct of two pipe connectors.
Object of the present invention also can be achieved by the following technical measures:
Between described floating ring and a pipe connector, be provided with elastic ring to guarantee sealing, between floating ring and this pipeline connecting parts, leave radial clearance; Between described floating ring and another pipe connector, being provided with bearing coaxial to guarantee, is Spielpassung between floating ring and this pipeline connecting parts; Described bearing is radial ball bearing.
The present invention has utilized the elasticity of elastic ring and the rigidity of sealing and bearing, and the amount of floating of fluid turn passage and these two conflicting requirements of sealing are separately processed.Between floating ring and a pipe connector, leave larger radial clearance and elastic ring is installed and keep sealing, the gap between the elasticity of elastic ring and two has met the requirement of amount of floating; Between floating ring and another pipe connector, leave less radial clearance and bearing is installed, while having guaranteed between these two rotation relatively, do not interfere and there is good sealing.Whole turn passage have reliability high and without wearing and tearing feature.Described larger radial clearance and less radial clearance all refer to the conventional use of the art.
The present invention is relatively rotating and is likely producing transmitting fluid between certain two eccentric parts, and guarantees that fluid passage has higher sealing.
accompanying drawing explanation:
Fig. 1 is the structure diagram of the embodiment of the present invention;
In figure: 1, pipe connector; 2, floating ring; 3, pipe connector; 4, bearing; 5, elastic ring.
embodiment:
Relevant detailed description of the present invention and technology contents, coordinate accompanying drawing to be described as follows, yet accompanying drawing only provides the use of reference with explanation, is not used for the present invention to be limited.
Shown in Fig. 1: this floating type fluid turn passage comprises needs counterrotating pipe connector 1 and pipe connector 3, at the floating ring 2 between pipe connector 1 and pipe connector 3, be located at elastic ring 5 between pipe connector 1 and floating ring 2, be located at the bearing 4 between pipe connector 3 and floating ring 2.
Described pipe connector 1 and pipe connector 3 are all with the duct in order to Fluid Transport; Described floating ring 2 also with duct in order to link up the duct of pipe connector 1 and pipe connector 3.
Described elastic ring 5 has elasticity and sealing, adopts rubber material; Described bearing 4 is radial ball bearing.
Between described pipe connector 1 and floating ring 2, leave larger radial clearance to meet amount of floating requirement; Between described pipe connector 3 and floating ring 2, leave less radial clearance to meet sealing requirements.
The present invention is specially adapted to lubricant oil and the transmission of control wet goods between centration axis and floating axle in mechanical transmission.
The foregoing is only preferred embodiment of the present invention, non-in order to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
