Abstract
The utility model provides a motor bearing, belongs to the technical field of machinery, and solves the problems that the existing motor bearing is short in service life and the like. The motor bearing comprises an inner ring, an outer ring and a rotating body disposed between the inner ring and the outer ring. Positioning blind holes are formed in the outer wall of the outer ring. An axis of each positioning blind hole is perpendicular to that of the outer ring. The outer ring is symmetrically arranged according to a plane where the axes of the positioning blind holes and the axis of the outer ring are located. A positioning pin is fixedly connected into each positioning blind hole. The outer end of each positioning pin extends out of the corresponding positioning blind hole. The motor bearing is good in work stability, long in 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 offers the location blind hole, the axis normal of described location blind hole in the axis of outer ring and outer ring the plane symmetry with the axis coexistence of the axis of location blind hole and outer ring arrange, be fixed with locating stud in the blind hole of described location, the location blind hole is stretched out in the outer end of described locating stud.
The location blind hole is arranged like this, 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, the outer end of locating stud penetrates bearing support and circumferentially locatees with bearing support, the inner of locating stud is arranged in the location blind hole, so the location has been realized in the outer ring, 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, the quantity of described location blind hole is 2 or 3 or 4 and the circumferential evenly layout of location blind hole at above-mentioned motor, and corresponding locating stud is connected in each location blind hole.The setting of a plurality of location blind hole and locating stud has strengthened locating effect, the outer ring firm position.
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 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 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.
Description of drawings
Fig. 1 is the structure sectional view that this motor is used bearing.
Fig. 2 is the structure sectional view that this motor is used outer ring in the bearing.
Among the figure, 1, inner ring; 2, outer ring; 3, rolling element; 4, location blind hole; 5, locating stud; 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 offers location blind hole 4, the axis normal of location blind hole 42 axis and outer ring 2 is arranged with the plane symmetry of the axis coexistence of the axis of location blind hole 4 and outer ring 2 in the outer ring, be fixed with locating stud 5 in the blind hole 4 of location, location blind hole 4 is stretched out in the outer end of locating stud 5.
Further describe in detail, in order to make outer ring 2 firm positions, the quantity of location blind hole 4 is 2 or 3 or 4 and location blind hole 4 circumferential evenly layouts, and corresponding locating stud 5 is connected in each location blind hole 4, as shown in Figure 2, outer ring 2 has 4 location blind holes 4 of circumferentially evenly arranging in the present embodiment.Use the working life of bearing in order to prolong this motor, 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.
After this motor is installed with bearing, the outer end of locating stud 5 penetrates bearing support and circumferentially locatees with bearing support, the inner of locating stud 5 is arranged in location blind hole 4, so the location has been realized in outer ring 2, circumferential rotation in use can not take place in outer ring 2, guarantee that this motor is stable with bearing working, prolonged working life, guarantee motor stabilizing work simultaneously.
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, location blind hole 4, locating stud 5, 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.
