Abstract
(B, ) the utility model relates to a bearing field, concretely relates to antiwear high -speed floating bearing. Set up annular oil trap on the internal diameter of its holder, the annular oil trap is symmetrical setting of the both sides of ball department, the quantity of every side ring shape oil trap is more than one, guide face department between holder and the inner circle is provided with the oil storage clearance, the lubricating oil that is used for bearing lubrication makes when passing through the holder, retain in the annular oil trap on the holder internal diameter, it locates to form the lubricating oil film at holder and inner circle guide face to be favorable to lubricating oil to be detained, realized that high -speed rotatory in -process holder of bearing and inner circle guide the delay oil storage effect of face department to the bearing oil, the inordinate wear of guide face has been avoided, do not change the main shaft structure, effectively avoid the emergence of wearing and tearing under the prerequisite of the lubricated design of system, guarantee the high -efficient operation of bearing. This kind of structure plan can extensively be applicable to other high -speed rotatory various entity holder bearings simultaneously, has improved the reliability of bearing life -span and use to a certain extent. (B, )
Description
Technical field
the utility model relates to field of bearings, is specifically related to a kind of antiwear high speed rotary bearing.
Background technique
along with improving constantly of its reliability requirement in bearing application process, the retainer part of one of the large fundamental parts of bearing four be it is also proposed to the usage requirement of high strength high reliability, to realize ensureing in separation, the high reliability smooth running guided in the process of rolling element.Particularly in the application of high speed, highi degree of accuracy, high reliability bearing, metal solid holding frame well meets these needs, and is widely used.According to the feature of metal solid holding frame, retainer guidance mode is that inner ring external diameter or outer ring internal diameter guide.For realizing the lubrication effect of guide surface, avoiding inordinate wear, realizing bearing high-efficiency operation, general employing retainer is silver-plated, lasso guide surface position arranges the methods such as lubricating oil portals, to a certain degree solve the inordinate wear problem of guide surface, but it is high to have corresponding cost, the shortcomings such as manufacturability difference.
Summary of the invention
for overcoming above-mentioned defect, namely the purpose of this utility model is to provide a kind of antiwear high speed rotary bearing.
the purpose of this utility model is achieved through the following technical solutions:
the antiwear high speed rotary bearing of one of the present utility model, comprising: inner ring, outer ring, retainer, ball; Described retainer is arranged between inner ring and outer ring, and described ball is arranged in retainer; The internal diameter of described retainer is provided with annular oil trap, and described annular oil trap is symmetrical arranged at the both sides place of ball, and the quantity of every side ring shape oil trap is more than one; Guide surface place between described retainer and inner ring is provided with oil storage gap.
the antiwear high speed rotary bearing of the one that the utility model provides, by arranging annular oil trap on the internal diameter of retainer, annular oil trap is symmetrical arranged at the both sides place of ball, the quantity of every side ring shape oil trap is more than one, guide surface place between retainer and inner ring is provided with oil storage gap, make when the lubricant oil being used for bearing lubrication is by retainer, retain in annular oil trap on retainer internal diameter, be conducive to lube oil retention and form lubricant film at retainer and inner ring guide surface place, to achieve in bearing high-speed rotation retainer and inner ring guide surface place to the delay oil storage effect of bearing oil, avoid the inordinate wear of guide surface, solve retainer in such high-speed bearing and and inner ring guide surface between the retainer that causes of the inordinate wear that produces damage and cause bearing integral Problem of Failure, do not changing main shaft structure, the generation of wearing and tearing effectively is avoided under the prerequisite of system lubrication design, ensure bearing high-efficiency operation.This kind of organization plan can be widely used in the various solid cage bearings of other High Rotation Speeds simultaneously, improves the reliability of bearing life and use to a certain extent.
Accompanying drawing explanation
for ease of illustrating, the utility model is described in detail by following preferred embodiment and accompanying drawing.
fig. 1 is the structural representation of a kind of antiwear high speed rotary bearing of the utility model;
fig. 2 is the structural representation that a kind of antiwear high speed rotary bearing of the utility model forms oil film;
fig. 3 is the structural representation of retainer in a kind of antiwear high speed rotary bearing of the utility model;
wherein reference character is: 1, inner ring; 2, outer ring; 3, retainer; 4, ball; 5, annular oil trap; 6, oil storage gap; 7, pocket hole; 8, lubricant film.
Embodiment
in order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
please refer to Fig. 1-3, the antiwear high speed rotary bearing of one of the present utility model, comprising: inner ring 1, outer ring 2, retainer 3, ball 4; This retainer 3 is arranged between inner ring 1 and outer ring 2, and this ball 4 is arranged in the pocket hole 7 on retainer 3; The internal diameter of this retainer 3 is provided with annular oil trap 5, this annular oil trap 5 is symmetrical arranged at the both sides place of ball 4, and the quantity of every side ring shape oil trap 5 is more than one; Guide surface place between this retainer 3 and inner ring 1 is provided with oil storage gap 6.
during use, the lubricant oil of bearing lubrication is by retainer 3, retain in annular oil trap 5 on retainer 3 internal diameter, be conducive to lube oil retention and form lubricant film 8 at retainer 3 with inner ring 1 guide surface place, specifically see Fig. 2, to achieve in bearing high-speed rotation retainer 3 with inner ring 1 guide surface place to the delay oil storage effect of bearing oil, avoid the inordinate wear of guide surface, the generation of wearing and tearing effectively is avoided under the prerequisite not changing main shaft structure, system lubrication design, ensure bearing high-efficiency operation, simple and practical.
the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
