Abstract
The utility model relates to a high-speed servo motor bearing which is designed aiming at solving the problem that an existing same-kind bearing is difficulty adapted to the requirements of high speed, high precision and long service life. The high-speed servo motor bearing comprises an inner ring, an outer ring, a steel ball, a retainer and a sealing ring, wherein the retainer is formed by a retainer upper sheet and a retainer lower sheet; each of the retainer upper sheet and the retainer lower sheet is provided with a semispherical pocket and a riveting face; and the semispherical pocket of the retainer upper sheet and the semispherical pocket of the retainer lower sheet are combined to form a spherical pocket for placing the steel ball. The design key points are that an oil storage tank is arranged at a connecting part of the retainer upper sheet and the retainer lower sheet and in the spherical pocket; and an annular oil tank which is communicated with the oil storage tank is arranged on the surface of the inner ring of the spherical pocket. The high-speed servo motor bearing disclosed by the utility model is reasonable in design, can be adapted to the requirements of high speed, high precision and long service life, is suitable for being used as various types of the high-speed servo motor bearings or can be used as structure improvement of like products.
Description
Technical field
The utility model relates to a kind of bearing, is a kind of high-speed servo motor bearing.
Background technique
Along with the mechanical field development, for machinery or instrument, require also more and more higher, especially relate to some control fields, as working machine tool, robot etc., and in these equipment, particularly important control object is high-speed servo motor, therefore, produces faster, more accurate, more durable, more efficient actuating motor and be one of task that mechanical field constantly looks for novelty.Such actuating motor, its corresponding bearing must move sooner, and namely (the dn value is greater than 1.0 * 10 for higher dn value
6, the dn value refers to the average diameter (mm) of main shaft bearing and the product of the limit speed (r/min) of main shaft).In tradition was used, general high-precision motor bearing all adopted the inlet angle contact ball bearing, although can adapt to high speed, highi degree of accuracy, long-life requirement, manufacture cost is higher, and resource consumption is larger; If adopt general deep groove ball bearing, can't satisfy again high speed, highi degree of accuracy, long-life requirement., need to improve existing deep groove ball bearing for this reason, make it be fit to high speed, highi degree of accuracy, long-life requirement.Notice of authorization CN202468715U as the Chinese patent literature publication, October 3 2012 notice of authorization day, the model utility name is called " a kind of oil storage tank retainer ", its main structure design is that the bottom in the middle of retainer ball pocket is provided with the oil storage tank of back side projection, by the lubrication problem of this kind structure with solution bearing steel ball when running up, but this kind effect structure is still unsatisfactory.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is that a kind of high-speed servo motor bearing is provided to related domain, makes it solve the existing more difficult adaptation high speed of similar bearing, highi degree of accuracy, long-life requirement.Its objective is and be achieved through the following technical solutions.
A kind of high-speed servo motor bearing, this bearing comprises inner ring, outer ring, steel ball, retainer, seal ring, retainer is made of sheet under retainer upper slice, retainer, under retainer upper slice and retainer, sheet is equipped with hemisphere pocket and riveted joint face, is combined to form the ball pocket of placement steel ball by the hemisphere pocket of sheet under the hemisphere pocket of retainer upper slice and retainer.Its structure outline is to be positioned in described ball pocket that under retainer upper slice and retainer, chip bonding place is provided with oil storage tank, and described ball pocket inner peripheral surface is provided with the annular oil groove that communicates with described oil storage tank.By above-mentioned oil storage tank and annular oil groove are set, improved the greasy property of bearing under running up, to adapt to bearing high speed, highi degree of accuracy, long-life requirement.
Under described retainer upper slice and retainer, riveted joint face corresponding to sheet is equipped with riveted joint mouthful and riveted joint button, and the riveted joint button of sheet under the riveted joint mouth of retainer upper slice, riveted joint button and retainer, riveted joint mouthful coordinate riveted joint.This kind riveting method is comparatively firm, and the retainer structure is comparatively reliable under in working order.
The utility model is rational in infrastructure, can adapt to high speed, highi degree of accuracy, long-life requirement, and be suitable as all kinds of high-speed servo motor bearings and use, or the architecture advances of like product.
