Abstract
The utility model discloses a lubrication enhanced type bearing retainer which comprises an annular frame body, wherein a plurality of outwards bulging baffling bars are axially arranged on the side wall of the frame body and are uniformly distributed on the annular side wall of the frame body at equal distances, a ball groove is formed between every two baffling bars, balls capable of freely rotating are placed in each ball groove, a clamping head is arranged at the end part of each ball groove, planes are arranged in the middles of two sides of each ball groove, a concave surface matched with the balls is arranged on the bottom surface of each ball groove, and defined space is formed in joints between the clamping heads and the planes as well as between the concave surfaces and the planes for storing lubricating grease. The lubrication enhanced type bearing retainer has the beneficial effects that the space for storing the lubricating grease is preserved in the ball groove, and thus the amount of the lubricating grease is increased, the friction between the balls and the retainer is reduced, the noise generated when a bearing works is reduced, and the service life of the bearing is prolonged; the clamping heads are arranged at one ends of the baffling bars, and thus the positions of the balls in the ball grooves are effectively limited so that the balls hardly drop.
Description
Technical field
The utility model relates to technical field of bearings, relates in particular to a kind of lubricated enhancement mode retainer.
Background technique
The retainer of conventional ball bearings is that ball is encased to a circle, and ball rotates in the pocket hole on retainer, and such retainer structure ball wearing and tearing are large, easily occur the phenomenon that ball is cracked or ball is stuck;
Traditional bearing mostly is metallic material and makes, the bearing that adopts metallic material to make, and high temperature resistant, wear resistance is all better, but metal bearing exists following defect:
First, metal bearing need to expend a large amount of metals, because bearing is the common part in machinery, annual use amount is very huge, all adopt metallic material to carry out processing and fabricating, can cause seriously expending of metallic material, the today of day by day riseing in metal price, this problem was just particularly outstanding.
Secondly, although metal bearing has high temperature resistant and anti abrasive advantage, the chemical property of metallic material is conventionally comparatively active, and the bearing that adopts metallic material to make, the corrosion of chemical formulation in use easily occurs, and causes bearing deformation and damage.
In present widely used bearing, generally all contain retainer, the acting as of retainer:
1. retainer is equally spaced by rolling element, is distributed on raceway and obtains on circumference when preventing work and collide with each other and rub between rolling element;
2. guide and drive rolling element to roll on correct raceway;
3. in divergence type bearing, by rolling element together with a collar combination, to prevent that rolling element from coming off.Rolling bearing is in the time of work, bearing heating and wearing and tearing are caused in sliding friction in mountain, and under high temperature operation condition, the effect of inertial centrifugal force has aggravated friction, wearing and tearing and heating especially, when serious, can cause retainer burn or fracture, cause bearing can not stop Chang Shangzuo.
Therefore, require the material of retainer except having some strength, also must thermal conductivity good, friction factor is little, wear resistance good, impact toughness is strong, density is less and linear expansion coefficient and rolling element are close.In addition, pressing cage need stand more complicated Pressing Deformation, also requires material to have good processibility.
The retainer that present stage is used; being mostly metallic material makes; owing to needing there is the hole of bead of placing bearing ball on retainer; therefore the ways that adopt metal cutting are processed more; not only cost is higher; and the metal fillings that processing produces is difficult to cleaning; often can cause frictional heat, not only affect the stability of bearing working, and frictional heat also can cause Bearing Temperature; easily be damaged; working life is lower, meanwhile, and the poor-performing of metal cage resist chemical; easily, by the chemical lubricants corrosion-deformation in bearing, cause damage.
Model utility content
Technical problem to be solved in the utility model: provide the lubricated enhancement mode retainer that a kind of greasy property is good, anticorrosion ability is good for the deficiencies in the prior art.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of lubricated enhancement mode retainer, comprise the support body of ring, on the sidewall of described support body, be axially arranged with the gear hurdle of some outwardly convexs, described gear hurdle is equidistantly distributed on the annulus sidewall of described support body, between adjacent two gear hurdles, form ball grooves, in each ball grooves, be all placed with ball free to rotate, the end of each ball grooves is provided with dop, its two middle side part is arranged to plane, the concave surface matching with described ball is arranged in its bottom, described dop and described plane, the jointing place of described concave surface and described plane all forms certain space in order to store lubricating grease.
In a preferred embodiment of the present utility model, described support body is one-body molded with gear hurdle.
In a preferred embodiment of the present utility model, described support body all adopts nylon material to make with gear hurdle.
Owing to having adopted technological scheme as above, the beneficial effects of the utility model are: the space that reserves supplying lubricating grease storage in ball grooves, increase the amount of lubricating grease, thereby effectively reduce the friction between ball and retainer, the noise sending while reducing bearing working, the working life of improving bearing; In gear one end, hurdle, dop is set, effectively defines the position of ball in ball grooves, make ball difficult drop-off; And support body and gear hurdle adopt nylon material to make, and make this support body have better corrosion resistance, extend its working life.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model is equipped with the ball grooves of ball.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the one providing in figure is lubricated enhancement mode retainer, comprises the support body 100 of ring, is axially arranged with the gear hurdle 110 of 12 outwardly convexs on the sidewall of support body 100,12 gear hurdles are equidistantly distributed on the annulus sidewall of support body 100, and support body 100 is one-body molded with gear hurdle 110.Between adjacent two gear hurdles 110, form ball grooves 120, in ball grooves 120, be all placed with ball free to rotate 130.
The end of ball grooves 120 is provided with dop 121, its two middle side part is arranged to plane 122, the concave surface 123 matching with ball 130 is arranged in its bottom, dop 121 forms certain space 210a, 210b with the jointing place of plane 122, concave surface 123 forms certain space 220a, 220b with the jointing place of plane 122, in these spaces 210a, 210b, 220a, 220b in order to store lubricating grease, owing to having increased the amount of lubricating grease, thereby make to reduce the friction between ball 130 and retainer, the noise sending while reducing bearing working, the working life of improving bearing.
