Abstract
The utility model relates to a bearing, which belongs to a mechanical part, mainly composed of an inner ring, an outer ring and a roller. Screw threads are arranged on the inner ring, the outer ring or the surface of the inner ring or the surface of the outer ring. The utility model has the advantages of simple structure, convenient installation and easy manufacture; the utility model can be used for various machines which need rotational connection such as axle shafts, apparatuses, instruments, etc.
Description
The utility model relates to a kind of novel bearing, belongs to a kind of mechanical parts.
At present, used bearing is formed by inner ring, outer ring and roller, and when mounted, sometimes outer ring and mounting hole interference compression fit, an inner ring and an axle interference compression fit sometimes, sometimes Internal and external cycle all with a mounting hole and an interference fit, so the machining accuracy and the hardness of bearing surface are had relatively high expectations, and the requirement on machining accuracy on the surface of mounting hole correspondingly and axle is also higher, the manufacturing procedure complexity, cost is higher, installs inconvenient.
The purpose of this utility model is a kind of bearing of design, and is simple in structure, easy for installation, easily processing.
The designed bearing of the utility model mainly is made up of inner ring, outer ring and roller, and roller is threaded on the outer surface of the internal surface of the outer surface of the internal surface of inner ring or outer ring or inner ring and outer ring between inside and outside circle.
For easy to use, the roller in the designed bearing can be ball, needle roller, roller or the like
The designed bearing of the utility model in use, the inner ring of bearing, outer ring or inside and outside circle cooperate fixedly connected with mounting hole or axle by screw thread, make axle minimizing resistance when rotating.
The advantage of the bearing that the utility model is designed is:
1. machining accuracy is lower, and is easy for installation.Do not need complicated process equipment and erection unit, the screw thread simple installation is easily gone.
2. reduced the cost of bearing.Bearing keeps having reduced on the basis of its function the requirement of machining accuracy, i.e. the requirement of bearing surface roughness reduces, so the cost of bearing reduces.
The designed bearing of the utility model can be used for being connected of revolving part and fixed block, as axletree, lathe or the like.
Fig. 1 is the sectional view of the designed a kind of bearing of the utility model.
Fig. 2 is the sectional view of the designed another kind of bearing of the utility model.
Fig. 3 is the sectional view of the designed another kind of bearing of the utility model.
In conjunction with specific embodiments the mode of execution and the effect of the designed bearing of the utility model is described further with reference to the accompanying drawings below.
Embodiment 1
Bearing as shown in Figure 1 is made up of inner ring 1, ball 2 and outer ring 3, is threaded 4 on inner ring 1, and the screw thread 4 of the inner ring 1 of bearing is connected with the screw-thread fit of axle head during installation, and the inner ring 1 of bearing rotated with axle when axle rotated.
Bearing as shown in Figure 2 is made up of inner ring 21, needle roller 22 and outer ring 23, and the screw thread 24 that is threaded the outer ring 23 of 24 bearings when installing on outer ring 23 is connected with screw-thread fit in the mounting hole, with being connected of realization fixed block and revolving part.
Bearing as shown in Figure 3 is made up of inner ring 31, roller 32 and outer ring 33, has internal thread 34 on inner ring 31, has outside thread 35 on outer ring 33.The outside thread 35 of the internal thread 34 of the inner ring 31 of bearing and outer ring 33 is connected with axle and mounting hole screw-thread fit respectively during installation.The inner ring 31 of bearing rotated with axle when axle rotated, and outer ring 33 is fixed with mounting hole.
Claims (2)
1. a bearing is made up of inner ring, outer ring and roller, and roller is characterized in that between inside and outside circle: be threaded on the outer surface of the internal surface of inner ring or outer ring, or all be threaded on the outer surface of the internal surface of inner ring and outer ring.
2 bearings according to claim 1. its feature also is: the roller between inside and outside circle can be ball, needle roller or roller.
