Abstract
A novel revolving cup bearing comprises a rolling body installed between an outer ring and a mandrel, a retainer insulates the rolling body, a dustproof ring is installed in a dustproof groove of the outer ring, and a positioning ring is installed on the outer circumferential surface of the outer ring. A mandrel step is installed in the middle of the mandrel, and the two ends of the mandrel step are transited to outer mandrel circles through the transition surfaces. The inner circumferential surface of the outer ring is provided with outer-ring inner grooves, and oil storage cavities are formed among the outer-ring inner grooves, an outer mandrel step circle and the outer mandrel circles. The novel revolving cup bearing is compact and reasonable in structure; the mandrel step is installed in the middle of the mandrel, and therefore the rigidity of the mandrel is enhanced, and the accuracy of the bearing will not decrease; in addition, due to the two oil storage cavities formed among the mandrel step arranged in the middle of the mandrel and the outer-ring inner grooves, after the novel revolving bearing runs for a period of time at a high speed, if the bearing lacks oil, grooves can be filled with grease in time, friction and abrasion among the rolling body, the outer ring and the mandrel in the novel revolving cup are reduced, the service life of the novel revolving cup is prolonged, and spinning quality is enhanced.
Description
Technical field
The present invention relates to the textile workpiece technical field, especially a kind of for the Novel rotor bearing on the rotor spinning machine.
Background technology
The rotor bearing that is used on the rotor spinning machine mainly is comprised of outer ring, mandrel, retainer, rolling element (roller or ball), dust ring, centring ring etc.Rolling element (roller or ball) is installed in employing between outer ring and mandrel, with retainer location, the even separation roller of retainer and maintenance rolling element proper exercise, dust ring is put in the dustproof groove of outer ring.This kind bearing core shaft poor rigidity, bearing is under continuous high speed running, high centrifugal force effect, and bearing accuracy obviously descends, and bearing is worn and torn rapidly, reduces service life; Bearing does not arrange rational oil-bearing structure in addition, make bearing under the continuous high speed running, after using a period of time, if can not in time replenish grease to bearing, can cause that bearing weares and teares rapidly, noise becomes large, and rotate and unstablely cause the surface to produce overheated and burn inefficacy, reduce service life.
Summary of the invention
The applicant provide a kind of device rational in infrastructure, thereby the mandrel middle part arranges a step for the medium shortcoming of above-mentioned existing production technology, has strengthened mandrel rigidity, and bearing accuracy can not descended; Mandrel step and outer ring inside groove form two oil-bearing structures in addition, make rotor bearing after a period of time that runs up, if bearing oil starvation, can make grease in time add in the groove, the frictionalwear of rolling element and outer ring, mandrel in the minimizing rotor bearing, prolong the life-span of rotor bearing, improve the quality of spinning.
The technical solution adopted in the present invention is as follows:
A kind of Novel rotor bearing comprises the rolling element of installing between outer ring and the mandrel, and retainer separation roller, dust ring are installed in the dustproof groove of outer ring, on the outer circumference surface of centring ring installation and outer ring; Described mandrel middle part is provided with the mandrel step, and the two ends of described mandrel step transit to the mandrel cylindrical by transition face; Have the outer ring inside groove on the inner peripheral surface of described outer ring, be formed with shoe cream room between described outer ring inside groove and mandrel step cylindrical and the mandrel cylindrical.
Its further technical scheme is:
Have the first outer ring inside groove and the second outer ring inside groove on the inner peripheral surface of described outer ring, described the first outer ring inside groove and the second outer ring inside groove form the first shoe cream room and the second shoe cream room respectively and between mandrel step cylindrical and the mandrel cylindrical;
Be provided with tank filler sleeve on the outer ring of corresponding the first shoe cream room and the second shoe cream room, on the described tank filler sleeve oiling ring be set;
The diameter a of described mandrel step is Φ 8mm～Φ 16mm; The length b of described mandrel step is 1mm～80mm.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable; By a mandrel step is set in the mandrel middle part, strengthened mandrel rigidity, bearing accuracy can not descended; Set mandrel step and the outer ring inside groove in mandrel middle part forms two oil-bearing structures in addition, make rotor bearing after a period of time that runs up, if bearing oil starvation, can make grease in time add in the groove, the frictionalwear of rolling element and outer ring, mandrel in the minimizing rotor bearing, prolong the life-span of rotor bearing, improve the quality of spinning.
