Abstract
The invention discloses a high-rotation-speed machine tool bearing, comprising a body (1), a bearing retainer (2), an inner ring (3), a bearing ball (4), an outer ring (5) and a concave part (6), wherein the bearing retainer (2) is arranged at the bottom of the inner side of the body (1), the concave part (6) is arranged at the top of the body (1), the outer ring (5) is arranged in the body (1) connected with the concave part (6), the inner ring (3) is arranged at the middle-upper part of the body (1), and the bearing ball (4) is arranged between the inner ring (3) and the outer ring (5). The high-rotation-speed machine tool bearing is simple in structure and convenient to use, and the service life is effectively prolonged while the rotation speed is promoted.
Description
Technical field
The present invention relates to machinery accessory technical field, be specifically related to a kind of high rotating speed machine bearing.
Background technique
Motor is the core of all lathe transferring power, the requirement of motor to bearing is also more and more higher, according to different equipment, motor requires that the precision of bearing is different, general bearing can reach Z1 group, reach Z2 group, Z3 group difficulty very large, the above motor bearings of Z4 group needs larger technique to drop into, and difficulty is very large.The motor bearings model of this project invention is NJ322EMA, and the feature of design reduces rolling element damping, improves motor bearings rotating speed.According to bearing under high speed conditions, produce rolling element damping position, retainer window structure is improved.This kind of motor bearings of current application, comprises bearing inner race, rolling element and bearing outer ring, retainer.Belong to common shape, i.e. bearing outer ring linearly raceway, inner ring is also straight line raceway, and the distance of interior raceway and outer raceway equals rolling return radius, and the ball axle of this structure only can bear radial load, can not bear thrust load.The rotating speed of this ordinary construction bearing is difficult to bring up to 7000-8000 and turns.Have on the special device of particular/special requirement many, existing ball bearing cannot meet the requirement of above equipment.For overcoming the not high defect of above roller bearing rotating speed, Curve guide impeller must be carried out to roller-mill bearing.
Summary of the invention
Instant invention overcomes above-mentioned shortcoming, and a kind of high rotating speed machine bearing is provided.
To achieve these goals, the present invention realizes by the following technical solutions: this high rotating speed machine bearing comprises body, retainer, inner ring, bearing ball, outer ring and depressed part, the inside bottom of described body arranges retainer, the top of body arranges depressed part, the body interior be connected with depressed part arranges outer ring, the middle and upper part of body arranges inner ring, arranges bearing ball between inner ring and outer ring; Described depressed part is cone or cylindrical body; The volume of described depressed part is 1/50 ~ 1/30 of bulk volume.
Described body is cylindrical body.
Described retainer is cylindrical body.
Described depressed part is cone.
The volume of described depressed part is 1/40 of bulk volume.
The invention has the beneficial effects as follows: structure is simple, easy to use, the while of carrying high-revolving, effectively increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication of reference character in figure, 1, body, 2, retainer, 3, inner ring, 4, bearing ball, 5, outer ring, 6, depressed part.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
This high rotating speed machine bearing to achieve these goals, the present invention realizes by the following technical solutions: this high rotating speed machine bearing comprises body 1, retainer 2, inner ring 3, bearing ball 4, outer ring 5 and depressed part 6, the inside bottom of described body 1 arranges retainer 2, the top of body 1 arranges depressed part 6, body 1 inside be connected with depressed part 6 arranges outer ring 5, the middle and upper part of body 1 arranges inner ring 3, arranges bearing ball 4 between inner ring 3 and outer ring 5; Described depressed part 6 is cone or cylindrical body; The volume of described depressed part 6 is 1/50 ~ 1/30 of body 1 volume; Body 1 is cylindrical body; Retainer 2 is cylindrical body; Depressed part 6 is cone; The volume of depressed part 6 is 1/40 of body 1 volume.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
