Abstract
The utility model relates to an axial limit device of a motor bearing, which comprises an end cover, a ball bearing arranged in a bearing housing of the end cover and a rotating shaft, wherein a limit baffle is arranged at the outer end of the ball bearing and is fixed on the inner wall of the end cover, and the rotating shaft penetrates through the limit baffle and is connected with the bearing. The axial limit device has a simple structure, and only one baffle needs to be added in the original structure, so that the bearing can be ensured to operate stably and reliably, the heat dissipation effect of the bearing is improved, the service life of the bearing is prolonged, and the axial limit device is convenient and practical.
Description
Technical field
The utility model belongs to machine field, is specifically related to a kind of axially stop block of motor bearings.
Background technology
Along with the fast development of science and technology, the application of rolling bearing more and more widely, especially at mechanical field.Rolling bearing is called for short bearing, is to be used for supporting axis rotation and bear the standarized component of load on axle, is called the joint of machinery by people, and for example motor does not have bearing just can not work.Rolling bearing of a great variety, but its structure is identical substantially, generally is made up of outer ring, inner ring, rolling element and retainer, and inner ring is contained on the axle, rotates with axle; The outer ring is contained in body or the bearing pedestal, generally maintains static.The fixed form of ball bearing and end cap has a variety of, for the mating surface slide relative that prevents inner ring and axle journal produces wearing and tearing, influence the service behaviour of bearing, thereby require to have certain interference between mating surface, but in the bigger occasion of variations in temperature, because bearing inner race, outer ring all are thin-walled parts, if the too big easy deformation of interference, so would be not suitable for adopting interference fit; And adopt gap or interference fits to tend to cause the axial restraint of bearing bad, cause bearing early failure.
Summary of the invention
For overcoming above-mentioned defective, the utility model provide a kind of simple in structure, reequip the axially stop block of motor bearings easily, it has not only limited the axial motion of motor bearings, and has guaranteed the high reliability of motor under high temperature and the high situation of shaking.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of axially stop block of motor bearings, comprise end cap, be installed in indoor ball bearing of end cap bearing and rotating shaft, outer end at ball bearing is provided with postive stop baffle, described postive stop baffle is fixed on the inwall of end cap, and described rotating shaft is passed postive stop baffle and is connected with bearing.
As further improvement of the utility model, be loop configuration with baffle design, and be provided with the annular protrusion that acts on the ball bearing outer ring, can limit the displacement of bearing on the one hand, can improve the radiating effect and the speed of bearing on the other hand.
The utility model guarantees stable, the operation reliably of bearing by at the end cap inner side end axial motion that postive stop baffle limits bearing being installed, and can improve the radiating effect of bearing, prolongs the useful life of bearing.
Description of drawings
Fig. 1 is the cutaway view of the utility model structure;
Fig. 2 is the front view of postive stop baffle in the utility model;
Fig. 3 is the A-A cutaway view of Fig. 2.
Among the figure: end cap 1, ball bearing 2, postive stop baffle 3, annular protrusion 3-1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment: referring to accompanying drawing 1, the utility model relates to a kind of axially stop block of motor bearings, comprise rotating shaft, end cap 1, ball bearing 2, described ball bearing 2 is installed in the bearing chamber of end cap 1, in order to prevent that ball bearing 2 from axially moving, fixedly install postive stop baffle 3 in the outside of end cap bearing chamber, described postive stop baffle 3 is provided with the rotating shaft passage, and the passage that rotating shaft is passed on the postive stop baffle during installation is connected with bearing 2.
As Fig. 2, shown in Figure 3: as described in postive stop baffle 3 be cirque structure, middle circular hole is the rotating shaft passage, and postive stop baffle 3 also is provided with the annular protrusion 3-1 that is used to prop up bearing outer ring, annular protrusion 3-1 is close to ball bearing 2 outer rings during installation, after postive stop baffle 3 is fixing with the inner side end welding of end cap.
The utility model is simple in structure, and only needing increases by a baffle plate on original structure, not only can guarantee stable, the operation reliably of bearing, can also improve the radiating effect of bearing, prolongs the useful life of bearing, and is convenient, practical.
Claims (2)
1. the axially stop block of a motor bearings, comprise rotating shaft, end cap and be installed in ball bearing in the bearing chamber of end cap, it is characterized in that: the outer end at ball bearing is provided with postive stop baffle, described postive stop baffle is fixed on the inwall of end cap, and described rotating shaft is passed postive stop baffle and is connected with bearing.
