Abstract
The utility model relates to a maintaining frame for the bearing and in particular to a maintaining frame for the column roller bearing. The utility model essentially comprises the blocking rings in both sides and a plurality of hole lintels which connect with the blocking rings; a plurality of holes are distributed evenly around the circumference of the maintaining frame; both ends of the hole walls on both sides of the hole lintels and the head face joint part in the inner side of the blocking ring on both sides are provided with concave oil grooves. The utility model can allow the lubricating oil to enter the surrounding walls of the holes easily to form a good oil film with the column roller to lubricate sufficiently and to reduce the friction lose. When the lubricating oil comprises certain impurities, the respectively heavier and bigger impurities enter the oil groove arranged on both sides of the hole with the oil and are not likely to enter the holes between the column roller and the holes of the maintaining frame; the utility model can effectively reduce the friction between the column roller and the maintaining frame caused by the impurities in the lubricating oil; the utility model can enhance the service life of the column roller bearing.
Description
Technical field
The utility model relates to a kind of nylon bearing retainer, especially relates to a kind of cylinder roller bearing retainer.
Background technique
Present disclosed nylon cylinder roller bearing retainer, the pocket hole wall surface of its lintel both sides, pocket hole and the arcuate surface of roller cylinder are basic identical, and pocket hole lintel is fixed on cylindrical roller in the pocket hole of retainer at the outward extending inside and outside fore shaft of pocket hole wall.But all do not have on the bi-side in its pocket hole wall of this kind structure retainer and pocket hole oil groove is arranged, though cylindrical roller is in the pocket hole of retainer in the rotary course, there is the fluid that splashes that the cylindrical roller surface is lubricated, to reduce the frictional force between cylindrical roller and the retainer pocket hole, but,, fluid forms good oil film with cylindrical roller so being difficult for entering in the pocket hole because the wall all around in pocket hole does not all have oil groove.Moreover, after bearing uses a period of time, owing to contain a certain amount of impurity in the lubricant oil, in running, the heavier granule foreign in the lubricant oil can't in time discharge, and impurity is stored between the pocket hole of cylindrical roller and retainer at bearing, not only increase the kinetic friction force between cylindrical roller and the retainer, cause noise and heating, also can damage retainer when serious, and shorten the working life of roller bearing.
Summary of the invention
The utility model is the deficiency that overcomes above-mentioned technology, and impurity in a kind of easy removal of lubricant is provided, and can reduce the cylinder roller bearing retainer of kinetic friction force between cylindrical roller and the retainer pocket hole.
For solving the technical problem of above-mentioned existence, the utility model adopts following technical proposals: a kind of cylinder roller bearing retainer, comprise the baffle ring of both sides and several pocket hole lintels between the connection baffle ring, the retainer circumference evenly is distributed as several pocket holes, the two ends of the pocket hole wall of lintel both sides, described pocket hole, the oil groove that all has indent with the pocket hole end surface joint of baffle ring inboard, both sides.
The pocket hole wall of beam sides is crossed in described pocket hole, the excessive face of in being provided with, receiving near all side faces of internal diameter place, and the flange that is connected with excessive face constitutes the fore shaft in pocket hole.
The pocket hole wall of lintel both sides, described pocket hole has the inclined-plane that communicates with oil groove near the flange two side ends.
Its outer side surface of the baffle ring of described both sides is all fluted.
Retainer of the present utility model compared with prior art has following beneficial effect: the utility model is provided with the oil groove of indent at the two ends of the both ends of the surface in retainer pocket hole and pocket hole lintel, when cylindrical roller in the pocket hole in the rotary course, make lubricant oil enter the wall all around in pocket hole easily on the one hand, form good oil film and carry out sufficient lubrication with cylindrical roller, reduce frictional loss.On the other hand, in lubricant oil, contain a certain amount of impurity, heavier relatively granule foreign then arrives in the oil groove of pocket hole two side ends with fluid, and be difficult for entering between the pocket hole on cylindrical roller and the retainer, therefore retainer of the present utility model is little to the receptance of fluid impurity, can effectively reduce because of the impurity in the lubricant oil causes and frictional force between cylindrical roller and the retainer pocket hole, can improve the working life of roller bearing so greasy property is good.Moreover the monocornered oral smallpox structure is adopted in the utility model pocket hole, helps the demoulding of mould manufacturing and retainer, and good manufacturability is easily manufactured.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the A-A sectional structure schematic representation of the utility model Fig. 2.
Fig. 2 is the sectional view of the B-B of Fig. 1.

Embodiment
Cylinder roller bearing retainer shown in Fig. 1～3, the baffle ring 1 that comprises both sides, 3 and be connected both sides baffle ring 1, several pocket hole lintels 2 between 3, the retainer circumference evenly is distributed as several pocket holes, the baffle ring 1 of cylinder roller bearing retainer of the present utility model both sides, 3 and pocket hole lintel 2 make the structure of one by engineering plastics, see Fig. 1, shown in 3, the two ends of the pocket hole wall 2-1 of lintel 2 both sides, pocket hole, with both sides baffle ring 1, the pocket hole end surface 1-1 of 3 inboards, the 3-1 joint all has the oil groove 4 of indent, fluid in the oil groove 4 can enter along the bi-side of pocket hole lintel 2 in the pocket hole, form good oil film with cylindrical roller, to reduce the motion frictional resistance.Moreover, can deposit heavier granule foreign relatively in by this oil groove 4, reduce the influence of impurity to the bearing operation.
For improving the technology capability of retainer, pocket hole wall 2-1 in lintel 2 sides, pocket hole, the excessive face 2-2 that in being provided with, receives near internal diameter circumferential surface place, the flange 2-3 that is connected with excessive face 2-2 constitutes the fore shaft in pocket hole, and the fore shaft at the internal diameter circumferential surface place by lintel 2 sides, pocket hole carries out spacing to cylindrical roller.
For increasing the oil reserve of oil groove 4, and make the pocket hole wall 2-1 of pocket hole lintel 2 have better Oil Guide performance, see shown in Figure 3, the pocket hole wall 2-1 in lintel 2 both sides, pocket hole, near flange 2-3 two side ends the inclined-plane 2-4 that communicates with oil groove 4 is arranged, fluid enters the pocket hole along the inclined-plane.
The utility model under the prerequisite of the intensity that does not influence retainer, the material of making for saving, see shown in Figure 2, at all fluted 1-2 of outer side surface, the 3-2 of the baffle ring 1,3 of both sides.
