Abstract
The utility model relates to a bearing end cover structure for a high-speed bearing. The bearing end cover structure comprises a bearing end cover basal body, floating seal rings and drawing seal strips, wherein the axial length of the bearing end cover basal body is longer than that of a common bearing end cover, and the ratio between the axial length and the section diameter of the bearing end cover basal body is 1/3 to 3/4; and the number of the floating seal rings and the drawing seal strips are correspondingly increased, the number of the floating seal rings is 2-4, and the number of the drawing seal rings is 5-10, so that the sealing effect is good, and the bearing end cover is prevented from oil leakage. The bearing end cover structure provided by the utility model has the characteristics of simple structure and good sealing property.
Description
Technical field
The utility model relates to a kind of bearing (ball) cover structure, and especially a kind of high-speed bearing is used the bearing (ball) cover structure.
Background technique
Sliding bearing is very extensive in the application of all trades and professions, and along with the continuous expansion and the continuous advancement in technology of sliding bearing application, the structure of sliding bearing also becomes increasingly complex.Be used for generator as some, blower fan, sliding bearings such as gear-box often need bear certain high rotating speed, generally are more than 3000r/min reaches.Because higher when the axle rotating speed, bearing inside often temperature is higher, is prone to produce mist of oil, spills from bearing (ball) cover along axle.And motor internal is equipped with fan sometimes, when the axle rotating speed is high, can produce bigger negative pressure, can make the leakage of oil more easily of bearing (ball) cover place like this.
Summary of the invention
The purpose of the utility model is that design is a kind of simple and compact for structure, can prevent that the high-speed bearing of bearing (ball) cover leakage of oil from using the bearing (ball) cover structure.The technological scheme of the utility model is so to realize:
A kind of high-speed bearing is used the bearing (ball) cover structure; Comprise the bearing (ball) cover matrix; Floating seal ring and drawing Stamping Steel Ribbon; Bearing (ball) cover matrix axial length is 1/3～3/4 of its end face diameter, and the quantity of being located at the floating seal ring on the bearing (ball) cover matrix is 2～4, and the quantity of being located at the drawing Stamping Steel Ribbon on the bearing (ball) cover matrix is 5～10.
The utility model designed high speed bearing is used the bearing (ball) cover structure; Comprise bearing (ball) cover matrix, floating seal ring, drawing Stamping Steel Ribbon, the bearing (ball) cover matrix increases than plain bearing end cap axial length, and its ratio with diameter of section is 1/3～3/4; And corresponding floating seal ring and the quantity that draws Stamping Steel Ribbon of having increased; Wherein the quantity of floating seal ring is 2～4, and the quantity that draws Stamping Steel Ribbon is 5～10, thereby has good sealing effect; Prevent the bearing (ball) cover leakage of oil, therefore the utlity model has characteristics simple in structure, good seal performance.
Description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing,, do further bright specifically to the technological scheme of the utility model through embodiment.
Embodiment: with reference to accompanying drawing; A kind of high-speed bearing is used the bearing (ball) cover structure, comprises bearing (ball) cover matrix 1, floating seal ring 2 and drawing Stamping Steel Ribbon 3; Bearing (ball) cover matrix 1 axial length is 1: 2 with the ratio of its end face diameter; The quantity of being located at the floating seal ring 2 on the bearing (ball) cover matrix 1 is 2, and the quantity that draws Stamping Steel Ribbon 3 is 7, has effectively prevented the bearing (ball) cover leakage of oil.
Bearing (ball) cover matrix 1 is processed by aluminium material, and floating seal ring 2 is processed by the Wear-resistant, high-temperature resistant polyimide is filled, does not does not wear and tear in order to protect a surface, draws Stamping Steel Ribbon 3 and is become by the softer metals copper.
Claims (1)
