Abstract
The utility model belongs to bearing mechanical field, is specifically related to a kind of sealing ultra high speed main shaft bearing, and the rolling element that it comprises raceway and is positioned at raceway, is provided with an oil layer between described raceway and rolling element; Described raceway two ends are provided with seal ring; Described rolling element is defined in rolling element in raceway by retainer.The utility model saves the operation that conventional art sprays lubricating oil atomization, and lubrication effect is better.
Description
Technical field
The utility model belongs to bearing mechanical field, is specifically related to a kind of sealing ultra high speed main shaft bearing.
Background technique
Main shaft bearing is the main shaft bearing of precision machine tool and similar devices, and it can ensure operating accuracy and the usability of precision machine tool.In conventional art, main shaft bearing in the time of high speed rotating in order to prevent that the rolling element of main shaft bearing and raceway, due to excessive damage of rubbing each other, need to constantly be sprayed on lubricating oil atomization on main shaft bearing.So, need a large amount of lubricant oil, produce wasting phenomena, time-consuming, take a lot of work, and also lubricated effect is not necessarily fine.
In view of this, the inventor invents a kind of sealing ultra high speed main shaft bearing, and this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of sealing ultra high speed main shaft bearing, to solve a large amount of lubricant oil of waste, and time-consuming, the technical problem of taking a lot of work.
For above-mentioned technical problem, the technological scheme that the utility model provides is: a kind of sealing ultra high speed main shaft bearing, comprise raceway and the rolling element that is positioned at raceway, and between described raceway and rolling element, be provided with an oil layer; Described raceway two ends are provided with seal ring; Described rolling element is defined in rolling element in raceway by retainer.
The utility model beneficial effect: be provided with an oil layer between the utility model raceway and rolling element, can play the effect of lubricated raceway and rolling element, can save the operation that conventional art sprays lubricating oil atomization, save a large amount of lubricant oil; Described raceway two ends are provided with seal ring, raceway can be formed to a confined space, prevent because the interference of outside air makes oil layer mummification.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is the utility model sectional view.
Embodiment
What the utility model disclosed as shown in Figure 1 is a kind of sealing ultra high speed main shaft bearing, comprises raceway 1 and the rolling element 2 that is positioned at raceway 1, is provided with an oil layer 3 between described raceway 1 and rolling element 2; Described raceway 1 two ends are provided with seal ring 4; Described rolling element 2 is defined in rolling element 2 in raceway 1 by a retainer 5.
Raceway of the present utility model becomes curved shape, and the middle circular arc roof 11 of raceway 1 just limits rolling element 2 to parcel, and described retainer 5 is fixed on raceway 1 horizontal interior walls 12, plays the effect of restriction rolling element 2, prevents rolling element 2 displacements; Raceway 1 two ends are provided with the seal ring 4 of rubber, and this two seal ring 4 can prevent that the oil layer 3 in raceway 1 from running outward, keep the environment in raceway 1 moistening, avoid because outside air impact makes oil layer 3 mummification; Described oil layer 3 is the special lubricant oil of ultra high speed, is specially the vigorous NBU15 of Crewe, and because the utility model is ultra high speed main shaft bearing, oil layer 3 can reduce the friction between raceway 1 and rolling element 2, plays protection raceway 1 and acts on rolling element 2.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
