Abstract
The invention belongs to the technical field of bearings and aims to overcome the defects that the traditional machine tool bearing retainer has heavy weight and poor lubricating function. The invention provides a high-speed angular contact ball bearing of a light-weight retainer with dual grooves. The common structure of the retainer is changed into a dual-groove shape. The retainer is provided with an inside-diameter groove and a small outside-diameter groove of a pocket, wherein the inside-diameter groove can reduce the weight of the retainer, has small inertial force when the bearing rotates at a high speed and is suitable for high-speed rotation. The small outside-diameter groove is guided by an outer ring; grease is stored in the outside-diameter groove; and a lubricating oil film is formed at a guide surface for ensuring the rotary stability of the retainer under the high speed condition, thereby achieving the aims of low heating and low friction at a high speed and improvement on the precision, the service life and the stability of the bearing.
Description
Technical field
The invention belongs to technical field of bearings, be particularly related to a kind of high-speed angular contact ball bearing with two groove light-weight retainers, this series products is that high-speed numeric control is upright, sleeping carriage bed, high speed boring, milling machine, at a high speed upright, the machining center that crouches is supporting, be applied at a high speed, high-accuracy, high rigidity machine tool field.
Background technique
Along with the fast development of home and abroad high-speed numeric control lathe, for its supporting high-speed machine tool main shaft bearing has become development trend.And at present machine bearing retainer Heavy Weight, lubricating function are poor, only are adapted to the low speed requirement, can't meet the demands to high-speed bearing.
Summary of the invention
At above deficiency, the invention provides a kind of high-speed angular contact ball bearing with two groove light-weight retainers, change the plain edition structure of retainer into " two groove " type, realize the low temperature rise under the high speed rotating situation, the performance of low noise and stable accuracy.
Technological scheme of the present invention is: the high-speed angular contact ball bearing of the two groove light-weight retainers of band, comprise outer ring 1, inner ring 2, steel ball 3 and retainer 4, retainer 4 is provided with the internal diameter groove 6 that pocket hole 5, retainer 4 internal diameters are provided with two symmetries, retainer 4 external diameters are provided with two semicircle external diameter minor grooves 7, and retainer 4 external diameters and bearing edge guard guide outward.
The invention has the beneficial effects as follows: the radial groove in two symmetries of retainer internal diameter design, alleviate retainer weight, inertial force is little during high speed rotating, suitable running up; Unique " two groove " type structure, can store a large amount of greases in the groove, when high speed rotating, grease is brought into raceway and guide surface place, make raceway and guide surface place form sufficient lubricant film, thereby the low heating under the realization high speed rotating, low friction has effectively improved bearing accuracy and working life and stability.
Description of drawings
Below in conjunction with drawings and the specific embodiments the present invention is elaborated:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of retainer 4 of the present invention.
Among the figure, 1, the outer ring, 2, inner ring, 3, steel ball, 4, retainer, 5, the pocket hole, 6, the internal diameter groove, 7, the external diameter minor groove.
Embodiment
As shown in Figure 1, the present invention includes outer ring 1, inner ring 2, steel ball 3, retainer 4, as shown in Figure 2, retainer 4 is provided with the internal diameter groove 6 that pocket hole 5, retainer 4 internal diameters are provided with two symmetries, and retainer 4 external diameters are provided with two semicircle external diameter minor grooves 7.Retainer 4 external diameters and bearing edge guard guide outward.
Pocket hole 5 is used for adorning steel ball, internal diameter groove 6 can be used for alleviating retainer weight, can store a large amount of greases in the groove, when high speed rotating, grease is brought into raceway and guide surface place, make raceway and guide surface place form sufficient lubricant film, thereby the low heating under realizing at a high speed improve loading bearing precision stability.External diameter minor groove 7 is stored greases, makes the guide surface place of retainer external diameter and bearing edge guard form sufficient lubricant film, raising bearing working life.
