Abstract
A novel rotor bearing comprises rolling bodies installed between an outer ring and a central spindle. Retainers isolate the rolling bodies. A dustproof ring is installed in a dustproof groove of the outer ring, and a locating ring is installed on the outer circumferential surface of the outer ring. A central spindle step is installed in the middle of the central spindle, and the two ends of the central spindle step are transited to the outer circle of the central spindle through transition surfaces. Outer ring inner grooves are formed in the inner circumferential surface of the outer ring, and oil storage cavities are formed among the outer ring inner grooves, the outer circle of the central spindle step and the outer circle of the central spindle. The novel rotor bearing is compact and reasonable in structure. By arranging the central spindle step in the middle of the central spindle, the rigidity of the central spindle is improved, and the accuracy of the bearing is not lowered. In addition, the two oil storage structures are formed between the central spindle step in the middle of the central spindle and the outer ring inner grooves, and therefore after the rotor bearing operates at a high speed for a period of time, if the bearing needs grease, the grease can be added to the grooves in time, friction and abrasion among the rolling bodies of the rotor bearing, the outer ring and the central spindle can be reduced, the service life of the rotor bearing is prolonged, and the spinning quality is improved.
Description
Technical field
The utility model relates to the textile workpiece technical field, especially a kind of for the Novel rotor bearing on rotor spinning machine.
Background technology
For the rotor bearing on rotor spinning machine, mainly by outer ring, mandrel, retainer, rolling element (roller or ball), dust ring, centring ring etc., formed.Rolling element (roller or ball) is installed in employing between outer ring and mandrel, and 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 of 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 supplement in time grease to bearing, can cause that bearing weares and teares rapidly, noise becomes large, and rotate the unstable surface that causes and produce overheated and burn inefficacy, reduce service life.
The utility model content
The applicant, for the medium shortcoming of above-mentioned existing production technology, provide a kind of device rational in infrastructure, thereby the mandrel middle part arranges a step, 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 add in time in groove, the frictionalwear of rolling element and outer ring, mandrel in the minimizing rotor bearing, extend the life-span of rotor bearing, improve the quality of spinning.
The technical scheme that the utility model adopts is as follows:
A kind of Novel rotor bearing, comprise the rolling element of installing between outer ring and mandrel, the retainer separation roller, and dust ring is installed in the dustproof groove of outer ring, and centring ring is installed on the outer circumference surface of 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, between described outer ring inside groove and mandrel step cylindrical and mandrel cylindrical, be formed with shoe cream room.
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 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 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.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, 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 add in time in groove, the frictionalwear of rolling element and outer ring, mandrel in the minimizing rotor bearing, extend the life-span of rotor bearing, improve the quality of spinning.
