Abstract
The utility model discloses a kind of adjustable bearing, comprise bearing outer ring and bearing inner race, ball is provided with between described bearing outer ring and described bearing inner race, the inner circle both sides of described bearing inner race are rotated and are provided with some first extension bars, also include two piece of first back-up ring, described first back-up ring is provided with near inner circle the first groove coordinated with described first extension bar.The inner ring of this bearing is set in rotating shaft, it is drawn close from two side direction of bearing inner race to adopt the first back-up ring of mating with rotating shaft of center hole, then the first back-up ring and rotating shaft with the first slot fit on the first back-up ring, can be fixed the fixed installation namely realizing bearing inner race and rotating shaft by the first extension bar.
Description
Technical field
The utility model belongs to technical field of bearings, specifically a kind of adjustable bearing.
Background technique
Existing bearing generally comprises bearing inner race, bearing outer ring, ball and retainer.The general inner ring of existing bearing mates with rotating shaft, and outer ring is mated with bearing support, and therefore bearing versatility is poor, and the specific model of general needs mates specific rotating shaft and mounting hole.
Summary of the invention
The utility model is not enough for prior art, and provide a kind of adjustable bearing, this bearing can be installed easily, and this bearing can be applicable to the different mounting point use of various sizes.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of adjustable bearing, comprise bearing outer ring and bearing inner race, ball is provided with between described bearing outer ring and described bearing inner race, the inner circle both sides of described bearing inner race are rotated and are provided with some first extension bars, also include two piece of first back-up ring, described first back-up ring is provided with near inner circle the first groove coordinated with described first extension bar.The inner ring of this bearing is set in rotating shaft, it is drawn close from two side direction of bearing inner race to adopt the first back-up ring of mating with rotating shaft of center hole, then the first back-up ring and rotating shaft with the first slot fit on the first back-up ring, can be fixed the fixed installation namely realizing bearing inner race and rotating shaft by the first extension bar.
In technique scheme, preferably, the cylindrical both sides of described bearing outer ring are rotated and are provided with some second extension bars, also include two piece of second back-up ring, and described second back-up ring is provided with near cylindrical place the second groove coordinated with described second extension bar.The outer ring of this bearing is arranged on in mounting hole, it is drawn close from two side direction of bearing outer ring to adopt the second back-up ring of mating with mounting hole of outer ring, then the second back-up ring and mounting hole with the second slot fit on the second back-up ring, can be fixed the fixed installation namely realizing bearing outer ring and mounting hole by the second extension bar.
The utility model compared with prior art, there is following beneficial effect: the inner ring of this bearing is set in rotating shaft, it is drawn close from two side direction of bearing inner race to adopt the first back-up ring of mating with rotating shaft of center hole, then the first back-up ring and rotating shaft with the first slot fit on the first back-up ring, can be fixed the fixed installation namely realizing bearing inner race and rotating shaft by the first extension bar.
