[model utility content]
In order to meet the need of market, the claimant develops a kind of chemical fiber high-speed spinning winding head hot-rolling bearing, this bearing criteria of right and wrong series be the ball ball bearing, it can be under 200 ℃ of high temperature conditions, with the high Growth spurt continuous operation of 8500～10000r/min, the life-span reaches 25000 hours.
The technological scheme that the utility model is taked is as follows:
A kind of chemical fiber high-speed spinning winding head hot-rolling bearing, comprise bearing outer ring, bearing inner race, steel ball and retainer, steel ball is installed in the retainer, the combination of steel ball and retainer is arranged between bearing outer ring and the bearing inner race, it is characterized in that: described retainer comprises sleeve body, hold the steel ball cavity volume of steel ball and make a concession breach, the external diameter of sleeve body and the difference of internal diameter are 4/5 ~ 3/5 of steel ball size, the steel ball cavity volume is opened on the sleeve body equably, and form opening at open end, the sphere centre of all steel ball cavity volumes is on the same circumference, the sphere centre of steel ball cavity volume is to the distance of flat end face than the radius of steel ball cavity volume large 1.5 ~ 5 millimeters, the opening size of each steel ball cavity volume is 9/10 ~ 6/10 of steel ball size, between the adjacent steel ball cavity volume of two-phase, be provided with the yielding breach on the open end, and at the both sides of steel ball cavity volume formation plasticity flap, the thickness of plasticity flap is 0.5 ~ 1.5 millimeter.
Further, the opening size of each steel ball cavity volume is 4/5 of steel ball size, and the thickness of plasticity flap is 1 millimeter.
Further, on the central position of flat end face, be provided with the material-saving groove corresponding to making a concession gap position.
Owing to changing retainer into the embed wholly structure by the separable assembled structure, this retainer can adopt the accurate compacting of heatproof plastics PEEK nylon to form, the steel ball cavity volume, plasticity flap and yielding breach can both rely on precision die to guarantee to make precision, steel ball can directly be pressed in the default steel ball cavity volume, both sides are enclosed by the plasticity flap, the actual faying surface of steel ball and steel ball cavity volume can reach more than 90%, can bear 200 ℃ temperature through test PEEK nylon cages, under the oil jet lubrication condition, this bearing just can be under the high speed of 8500 ~ 10000r/min continuous operation, the life-span reaches 25000 hours.
