[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, they have larger radial dimensions, larger vibrations and noises, and are more expensive. Traditional bearing seats have weak impact resistance and are easily damaged by external impacts, resulting in damage to the bearing structure.

[0003] In response to the above problem, a Chinese patent announcement with announcement number CN212717658U discloses an impact-resistant vertical spherical bearing seat, the technical key points of which are: it includes a bearing, an outer shell is arranged around the outer surface of the bearing, both ends of the outer shell are connected to a base, a groove is opened on the inner side of the base, a connecting mechanism is connected to the inner side of the groove, and an anti-impact mechanism is arranged above the connecting mechanism.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 As shown, the utility model provides a technical solution: an impact-resistant outer spherical bearing seat, comprising a bottom plate 1, a base 2, two vertical rods 3, a clamping block 4, an outer cylinder 7, an inner cylinder 8 and two protective plates 11, the bottom plate 1 is provided with four mounting holes 19 which are symmetrically distributed in pairs, the base 2 is fixedly mounted on the top of the bottom plate 1, the two vertical rods 3 are fixedly mounted on the top of the base 2 and are symmetrically distributed, the bottom of the clamping block 4 is provided with two vertical grooves 5, the clamping block 4 can clamp and support the outer cylinder 7, and the protective cover 1 6 is used for support and reinforcement to improve the impact resistance of the bearing seat. The two vertical rods 3 are slidably installed in the two vertical grooves 5 respectively. The top of the base 2 and the bottom of the clamping block 4 are both provided with arc-shaped clamping grooves 6. The outer cylinder 7 is detachably installed in the arc-shaped clamping groove 6 below, and the inner cylinder 8 is rotatably installed in the outer cylinder 7. Two protective plates 11 are respectively arranged on the front and rear sides of the base 2. It should be noted that the bearing includes an outer cylinder 7 and an inner cylinder 8. By detachably installing the outer cylinder 7 in the arc-shaped clamping groove 6 on the lower side, the inner cylinder 8 can be supported to rotate freely.

[0026] In this embodiment, the two protective plates 11 are each provided with a circular hole 12, and protective tubes 13 are threadedly installed in the two circular holes 12. The ends of the two protective tubes 13 that are away from each other extend to the front and rear sides of the base 2 respectively. The inner diameters of the two protective tubes 13 are both larger than the outer diameter of the outer tube 7. The two protective tubes 13 can effectively protect the bearings and avoid direct contact with external impact.

[0027] In this embodiment, two symmetrically distributed positioning grooves 9 are provided on the front and rear sides of the above-mentioned base 2, and two positioning rods 10 are fixedly installed on the sides where the two protective plates 11 are close to each other. The four positioning rods 10 are slidably installed in the corresponding positioning grooves 9 respectively. The sides where the two protective plates 11 are close to each other are respectively in close contact with the front and rear sides of the base 2.

By using the protective plates 11, protective tubes 13 and protective covers 16, the impact resistance of the top and front and rear sides of the bearing seat is greatly improved, thereby extending the service life of the bearing.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
