Abstract
The utility model relates to a high-speed open-end-bearing which comprises an outer ring, a spindle, a retainer and a sealing part. The high-speed open-end-bearing is characterized in that a ceramic ball is arranged on a ball track between an outer ring and the spindle, the retainer is made of phenol resin, and the pocket of the retainer is a cylindrical hole. An oil penetration layer is arranged on the retainer. The utility model has the advantages that the centrifugal force generated by the steel ball at high speed can be greatly reduced by adopting the ceramic ball, a small amount of lubricating oil is distributed in the retainer body after the special oil penetration treatment is performed to the retainer and the retainer passes through the pocket of the cylindrical hole, and thereby the service speed of the bearing is greatly increased.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of high velocity air rotor bearing.
Background technology
The open-end spinning machine technology is the new breakthrough of cotton spinning technology, it has not only improved the efficient of spinning greatly but also has improved the quality level of institute spinning yarn, the open-end spinning technology is progressively substituting traditional spinning technique at present, because open-end spinning is by improving the rotating speed of rotor, make the interior air-flow that forms of cup make noodles be spun into the yarn that needs through combing, rotation frame groundwork position is the spinning head, a spinning center is equipped with the open-end spinning special bearing, this bearing is sealing, the biserial ball, axle links structure (as shown in Figure 1), the bearing outer ring external diameter is for installing locating surface, raceway is made on the mandrel in the bearing, the mandrel two ends grow cycle surface, one end is used to install cup, and the other end presses the friction-driven running by belt, and the air-flow cup of usefulness is high owing to heating appears in the influence that is subjected to bearing performance at present, the problem that life-span is short.
Summary of the invention
The purpose of this utility model is to solve the problem that prior art solves high speed rotor bearing commonly used initial failure when high speed is practical, and a kind of high velocity air rotor bearing is provided.The utility model designs a kind of high velocity air rotor bearing, comprises outer ring, mandrel, retainer, seal, it is characterized in that: be Ceramic Balls on the raceway between outer ring and the mandrel, retainer is phenolic resins in view of this, and the pocket hole of retainer is a cylindrical hole.Oil seepage layer is arranged on the retainer.The utility model has the advantages that and adopt Ceramic Balls can significantly reduce the centrifugal force of steel ball in generation at a high speed, retainer is through the special oil impregnate processing and the pocket hole of cylindrical hole, make to keep being distributed with a spot of lubricating oil in the support body, the use rotating speed of bearing is significantly improved again.
Description of drawings
Accompanying drawing 2 is a structural representation of the present utility model,
Accompanying drawing 3 is a retainer structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
The specific embodiment
Comprise outer ring 1, mandrel 2, retainer 3, seal 7 among the figure, it is characterized in that: be Ceramic Balls 5 on the raceway 4 between outer ring 1 and the mandrel 2, retainer 3 is a phenolic resins, and the pocket hole 6 of retainer 3 is a cylindrical hole.On the retainer 3 oil seepage layer is arranged.The utility model is owing to adopted precise ceramic ball to substitute original steel ball structure, and the density of Ceramic Balls 5 has only about 40% of steel ball, can significantly reduce the centrifugal force of ball in generation at a high speed like this, makes bearing become the new structure pair of steel porcelain mixed type; Retainer 3 has adopted outer land riding cage 3 structures of the high-strength phenolic resin folder stringing of crown structure as material, and retainer 3 pocket holes 6 are changed into the shape of cylinder pass by original ball-type pocket hole; After the improvement structure, retainer 3 and the 1 grade of limit guide surface in outer ring when bearing operation, and maintain an amount of lubricating oil between Ceramic Balls 5 and the retainer 3 pocket holes 6, improve lubricated effect thereby play, satisfied the high speed rotating of bearing between 60000-120000rpm, made it prolong for 50% above life-span in the life-span of using at a high speed.
Claims (2)
1, a kind of high velocity air rotor bearing comprises outer ring, mandrel, retainer, seal, it is characterized in that: be Ceramic Balls on the raceway between outer ring and the mandrel, retainer is a phenolic resins, and the pocket hole of retainer is a cylindrical hole.
2, by the described a kind of high velocity air rotor bearing of claim 1, it is characterized in that: oil seepage layer is arranged on the retainer.
