Abstract
A tallow lubricant high speed removable pressurized angular contact ball bearing is formed by an inside race, a housing washer, a rolling element, a retainer, a dust guard, and a spring collar. The dust guard is fixed in a sealing flute of the housing washer via the spring collar. The dust guard is easy to assemble and disassemble. The high speed removable pressurized angular contact ball bearing with the advantages of well sealing effect, outstanding rapid property, high manufacturing accuracy, and long performance life is an ideal tallow lubricant bearing product designed for high speed precise machinery region.
Description
Technical field:
The utility model belongs to technical field of rolling bearings, a kind of high speed detachable type seal angle contact ball bearing.
Background technique:
Angular contact ball bearing is as a kind of structure type of rolling bearing, and at present, common angular contact ball bearing all is the open architecture form of not being with obturator basically, and promptly bearing only is made up of inside and outside lasso, rolling element, retainer and oiling agent five parts.Two kinds of oil lubrication in lubricated minute of bearing and grease lubrication.In the application that needs adopt grease lubrication, when using the bearing of this open architecture, exist raceway and be difficult for depositing shortcomings such as fat, lubrication effect is poor, the life-span is lower.
Summary of the invention:
Defective such as adopt in order to solve the open architecture angular contact ball bearing that grease lubrication hourglass fat is serious, insufficient lubrication, working life are low, the utility model provides a kind of high speed detachable type seal angle contact ball bearing, makes that it has good sealing effect, anti-dust performance is good, accuracy of manufacturing is high, advantage such as easy to loading and unloading, long working life.
For achieving the above object, the present invention adopts following technological scheme:
A kind of high speed detachable type seal angle contact ball bearing is made up of inside and outside lasso, dust cover, check ring, rolling element, retainer, and wherein design has seal groove on the outer collar, and the two ends dust cover is fastened in the seal groove of outer collar by the check ring at two ends; Leave a very little radial clearance between inside race and the dust cover.
The dust cover at two ends can be designed to identical size, also can be designed to different sizes.
Owing to adopted technological scheme as mentioned above, the utlity model has following superiority:
Shortcomings such as the lubrication effect when having improved open architecture angular contact ball bearing employing grease lubrication is poor, anti-dust performance is bad, working life is short, control and design by bearing internal structure parameter (as sphere diameter, nodule number, lasso groove curvature radius etc.), increased Sealing, can prevent foreign or dust intrusion bearing inside, simultaneously can also stop lubricating grease outwards to overflow, can guarantee that bearing has higher speed ability, and, also have simple in structure, easy to loading and unloading, accuracy of manufacturing advantages of higher.
Description of drawings:
Fig. 1 is a high speed detachable type seal angle contact ball bearing structural representation.
1. inside races among the figure; 2. dust cover (two ends each); 3. check ring (two ends each); 4. outer collar; 5. retainer; 6. rolling element.
Specific embodiment:
There are seal groove, lubricating grease to be filled in bearing inside in the last design of the outer collar (4) of high speed detachable type seal angle contact ball bearing.The dust cover at two ends (2) is fastened in the seal groove of outer collar (4) by the check ring (3) at two ends, keeps relative position constant in the bearing rotary course, and therefore, bearing seal is effective, and lubricating grease is difficult for excessive, has improved lubrication effect; The dust cover assembling can freely be dismantled easily.Between inside race (1) and the dust cover (2) a very little radial clearance is arranged, during the bearing working, can relative high speed rotating between inside race (1) and the dust cover (2), and can stop lubricating grease outwards to overflow again, can also prevent simultaneously foreign or dust intrusion bearing inside, the working life of improving bearing.In addition, inside race (1) with respect to outer collar (4) rotation, retainer (5) plays isolation by rolling element (6), divide equally rolling element (6), prevent to collide, reduce friction, improve effects such as lubricated.
In addition, assembling is convenient on an end band slope of inside race (1) cylindrical, and the other end has step.The dust cover at bearing two ends (2) can be designed to identical size, also can be designed to different sizes.
Claims (2)
1. high speed detachable type seal angle contact ball bearing, form by inside and outside lasso, rolling element, retainer, it is characterized in that: going up design at its bearing outside collar (4) has seal groove, and the dust cover at two ends (2) is fastened in the seal groove of outer collar (4) by the check ring (3) at two ends; Leave a very little radial clearance between inside race (1) and the dust cover (2).
2. high speed detachable type seal angle contact ball bearing according to claim 1, it is characterized in that: the dust cover at two ends (2) can be designed to identical size, also can be designed to different sizes.
