Abstract
The utility model provides a motor bearing, belongs to the technical field of machinery and solves the problem that the outer ring of the existing bearing cannot be positioned. The motor bearing comprises an inner ring, an outer ring, and balls located between the inner ring and the outer ring. The outer wall of the outer ring is peripherally provided with a circular groove coaxial with the outer ring. The outer ring is symmetrical to the circular groove. A positioning snap ring is fixedly connected in the circular groove and is provided with an opening. The motor bearing has the advantages of fine operational stability, long service life and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bearing, particularly a kind of motor bearing.
Background technique
Bearing is used for determining running shaft and other part relative movement positions, plays the part of supporting or leading role, and existing bearing generally comprises inner ring, outer ring and the rolling element between inner ring and outer ring.
Bearing is widely used at motor, the rotating shaft of motor pass inner ring and with the inner ring interference fit, be installed on the bearing support to the outer ring interference fit of bearing, the rotating shaft of motor is rotated and is driven inner ring and rotate, yet rotating speed of motor is very fast, when the outer ring stressed big or use a period of time after, the situation that circumferentially rotate the outer ring can take place in the outer ring vibration, influence the stability of bearing working like this, shortened the working life of bearing, and made the machine operation instability.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, the motor bearing that provides a kind of outer ring to locate.
The purpose of this utility model can realize by following technical proposal: a kind of motor bearing, comprise inner ring, outer ring and the rolling element between inner ring and outer ring, it is characterized in that, the outer wall of described outer ring circumferentially offers the annular groove of arranging with the outer ring coaxial line, described outer ring is symmetrical in annular groove and arranges, be fixed with the location snap ring in the described annular groove, described location snap ring has opening.
The location snap ring is arranged in annular groove, does not protrude from the outer wall of outer ring, can not interfere the installation of bearing of this motor; Annular groove is arranged between two parties, makes the outer ring stressed evenly, and eccentric vibration, outer ring long service life can not take place in the course of the work in the outer ring.After this motor is installed with bearing, keep out on bearing support at the opening two end part of location snap ring, the location snap ring is circumferentially located, just realized the location with the outer ring that is connected of snap ring, location like this, circumferential rotation in use can not take place in the outer ring, guarantee that this motor is stable with bearing working, prolonged working life, guarantee motor stabilizing work simultaneously.
With in the bearing, described location snap ring is bonded in the annular groove by glue at above-mentioned a kind of motor.
As another kind of situation, with in the bearing, described annular groove bottom offers isometric with the location snap ring together locating slot at above-mentioned a kind of motor, and snap ring bottom in described location has the positioning block that is embedded in the above-mentioned locating slot.Positioning block is embedded in the locating slot, and circumferentially locate location snap ring and outer ring, and because the elasticity of location snap ring self, location snap ring chucking is connected in the groove, locatees the quick and easy for installation of snap ring like this.
With in the bearing, described inner ring and both sides, junction, outer ring are equipped with annular dust cover and O-ring seal at above-mentioned a kind of motor, and seal ring is between dust cover and rolling element.The setting of dust cover and seal ring prevents that impurity such as dust from entering the rolling element place, avoids the rolling element wearing and tearing, has prolonged working life.
With in the bearing, be filled with lubricant oil in the cavity between described rolling element and the seal ring at above-mentioned a kind of motor.Guarantee the lubricity at rolling element place like this, reduce the rolling element wearing and tearing, prolonged working life.
Compared with prior art, this motor has been realized the location with the outer ring of bearing, circumferential rotation in use can not take place in the outer ring, guarantee that this motor is stable with bearing working, prolonged working life, guarantee motor stabilizing work simultaneously, dust cover, seal ring and lubricant oil setting in addition further prolonged this motor with the working life of bearing.

Among the figure, 1, inner ring; 2, outer ring; 3, rolling element; 4, annular groove; 4a, locating slot; 5, location snap ring; 5a, positioning block; 6, dust cover; 7, seal ring; 8, lubricant oil.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this motor comprises inner ring 1, outer ring 2 and the rolling element 3 between inner ring 1 and outer ring 2 with bearing, the outer wall of outer ring 2 circumferentially offers the annular groove of arranging with outer ring 2 coaxial lines 4, outer ring 2 is symmetrical in annular groove 4 and arranges, be fixed with location snap ring 5 in the annular groove 4, location snap ring 5 has opening.
Further describe in detail, quick and easy for installation in order to locate snap ring 5, as shown in Figures 2 and 3, location snap ring 5 is 2/3rds annulus, annular groove 4 bottoms offer together the locating slot 4a isometric with location snap ring 5, snap ring 5 bottoms, location have the positioning block 5a that is embedded among the locating slot 4a, and location snap ring 5 can be bonded in the annular groove 4 by glue when reality was made certainly.In order to increase the service life, inner ring 1 and both sides, 2 junction, outer ring are equipped with annular dust cover 6 and O-ring seal 7, and seal ring 7 is filled with lubricant oil 8 in the cavity between rolling element 3 and the seal ring 7 between dust cover 6 and rolling element 3.Rolling element 3 is steel ball in the present embodiment.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as inner ring 1, outer ring 2, rolling element 3, annular groove 4, locating slot 4a, location snap ring 5, positioning block 5a, dust cover 6, seal ring 7, lubricant oil 8 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
