Abstract
The utility model relates to a device for preventing the abrasion of a bearing outer ring, and aims at solving the problems that the service lives of the conventional bearings are shortened as the outer rings are easily abraded after long term running. The device for preventing the abrasion of the bearing outer ring is characterized in that two straight grooves (3) are symmetrically formed in the end surface of one side of the bearing outer ring (2); and convex keys (5) are embedded in the positions on the end surface of the inner side of a bearing end cover (4), opposite to the straight groves (3). The device can effectively prevent the abrasion of the bearing outer ring to stabilize the running of equipment and prolong the service life of the bearing.
Description
Technical field
The utility model relates to a kind of mechanical field, specifically a kind of device that prevents the bearing outer ring wearing and tearing.
Background technique
Bearing on the motor is after long-term operation, because the wearing and tearing of bearing, make the gap between bearing outer ring and the bearing (ball) cover increasing, cause equipment axis decentraction, make bearing outer ring wearing and tearing (be commonly called as bearing act as a travelling agent circle), it is moving that the running device of motor and pump produces huge violent shock, reduces the working life of bearing.
Summary of the invention
Easy to wear and shorten the bearing deficiency in working life in order to overcome existing bearing outer ring after long-term operation, the utility model provides a kind of device that prevents the bearing outer ring wearing and tearing, this device can effectively prevent the bearing outer ring wearing and tearing, makes equipment operation stable, prolongs the working life of bearing.
The technical solution of the utility model is: a kind of device that prevents the bearing outer ring wearing and tearing, comprise bearing outer ring, bearing (ball) cover, symmetry has two grooves on described bearing outer ring one side end face, and the position relative with groove is inlaid with the key of protrusion on the bearing (ball) cover inner side end.
The utlity model has following beneficial effect: owing to take such scheme, by having groove at bearing outer ring, be inlaid with key on the bearing (ball) cover, key and groove are matched, thereby bearing can be fixed, solve the problem of bearing outer ring wearing and tearing, also can avoid carrier wear, prolonged the working life of bearing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-bearing support among the figure, 2-bearing outer ring, 3-groove, 4-bearing (ball) cover, 5-key.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of device that prevents the bearing outer ring wearing and tearing comprises bearing support 1, bearing outer ring 2, bearing (ball) cover 4, symmetry has two grooves 3 on described bearing outer ring 2 one side end faces, as preferably, the degree of depth of groove 3 is 0.5mm-1mm, and width is determined according to the bearing size.The position relative with groove 3 is inlaid with the key 5 of protrusion on bearing (ball) cover 4 inner side ends, and key 5 is fixed on the bearing (ball) cover 4, avoids it to come off, and the size of key 5 matches with groove 3, and key 5 can be stuck in the groove 3.
Motor in the running, the key 5 on the bearing (ball) cover 4 contacts cooperation with groove 3, can rigid bearing, avoid bearing outer ring 2 wearing and tearing, also can avoid bearing support 1 wearing and tearing simultaneously, make equipment operation stable, prolonged the working life of bearing.
Claims (1)
1. device that prevents bearing outer ring wearing and tearing, comprise bearing outer ring (2), bearing (ball) cover (4), it is characterized in that: symmetry has two grooves (3) on described bearing outer ring (2) one side end faces, and the position relative with groove (3) is inlaid with the key (5) of protrusion on bearing (ball) cover (4) inner side end.
