Description

Technical Field

[0001] The utility model relates to an assembled bearing. Background Art

[0002] As an important supporting part in mechanical equipment, the installation method of the bearing directly affects the operation performance and service life of the equipment. The existing assembled bearings usually need to be assembled vertically in an up-and-down manner, and this installation method is widely used in various mechanical equipment.

[0003] The existing bearing assembly process is usually as follows: First, fix the lower bearing on the equipment base; then place the upper bearing directly above the lower bearing; next, connect and fix the upper and lower bearings with multiple bolts; finally, additional support members need to be installed to ensure the stability of the upper bearing. This installation method requires strict coaxiality and parallelism to ensure the normal operation of the bearing.

[0004] However, the existing assembled bearings have obvious technical defects. The main problem is that the installation process is cumbersome and the structure is complex. Since the upper bearing usually has a large mass, it is difficult to ensure long-term stable operation only by bolt connection. To solve this problem, additional support parts have to be added to strengthen the fixation, which not only increases the number of parts but also makes the installation process more complex.

[0005] During the actual installation process, the operator needs to coordinate the tightening force of multiple bolts simultaneously to ensure the centering of the upper and lower bearings. This adjustment process not only takes time but also is prone to installation accuracy deviation due to improper operation. Especially in the occasions where frequent disassembly and maintenance are required, the complex fixing method significantly increases the maintenance workload.

[0006] Therefore, it is of great practical significance to develop an assembled bearing with a simple structure and convenient installation. This design needs to be able to simplify the installation process, reduce the number of parts, improve the installation efficiency and use reliability while ensuring the stability of the upper bearing. Summary of the Utility Model

[0007] The purpose of the utility model is to provide an assembled bearing. This assembled bearing can improve stability and installation efficiency.

[0008] The above technical purpose of the utility model is achieved through the following technical solutions:

[0009] An assembled bearing, comprising: an upper bearing and a lower bearing, on both of which are symmetrically provided fixing bolts, the fixing bolts including nuts and screw rods; a fixing block provided at one end of the upper bearing; a positioning seat provided on the lower bearing, and a fixing groove corresponding to the fixing block is provided on the positioning seat; hinge seats provided on both sides of the positioning seat; an arc-shaped plate hingedly provided on the hinge seats, and the shape of the arc-shaped plate is adapted to the outer shell of the upper bearing; a hinge shaft connecting the arc-shaped plate and the hinge seats; and a torsion spring provided on the hinge shaft.

[0010] The present utility model is further provided that: the fixing bolts are used to fixedly connect the ball bracket in the upper bearing and the bearing outer shell to each other.

[0011] The present utility model is further provided that: the fixing block penetrates into the fixing groove to realize the preliminary fixation of the upper bearing and the lower bearing.

[0012] The present utility model is further provided that: the end of the arc-shaped plate penetrates between the nut of the fixing bolt and the outer shell of the upper bearing.

[0013] The present utility model is further provided that: the torsion spring has a reverse elastic force for maintaining the support of the upper bearing.

[0014] The present utility model is further provided that: when the upper bearing moves downward, it presses the arc-shaped plate, causing the arc-shaped plate to rotate to abut against the upper bearing correspondingly.

[0015] The present utility model is further provided that: the end of the arc-shaped plate penetrates between the nut and the outer shell to complete the clamping and fixation of the arc-shaped plate.

[0016] The present utility model is further provided that: the torsion spring and the fixing bolts are cooperatively fixed to realize the stable connection between the upper bearing and the lower bearing.

[0017] In summary, the present utility model has the following beneficial effects:

[0018] The assembled bearing adopts a fixing mechanism, realizes preliminary positioning through the cooperation of the fixing block and the positioning seat, and then automatically clamps the arc-shaped plate with a torsion spring into the gap between the fixing bolt and the bearing outer shell to complete the stable connection of the upper and lower bearings. By using the fixing bolts of the bearing itself without additional fasteners, it not only simplifies the installation steps but also ensures the reliability of the connection. The characteristic that the arc-shaped plate can automatically rotate and lock during the downward pressing of the upper bearing, combined with the reverse supporting force of the torsion spring, provides a continuous and stable supporting force for the upper bearing, solves the problems of cumbersome installation and complex structure of traditional assembled bearings, significantly improves the installation efficiency, and reduces the maintenance cost.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As Figure 1As shown, an assembled bearing includes an upper bearing 1 and a lower bearing 2. Symmetric fixing bolts 3 are provided on both the upper bearing 1 and the lower bearing 2. The fixing bolt 3 includes a nut 4 and a screw rod 5. The fixing bolt 3 is used to fixedly connect the ball bracket 6 in the upper bearing 1 and the bearing housing 7, and it is an essential fixing part of the bearing itself.

[0029] As Figure 2 , Figure 3 , Figure 4 shown, a fixing block 8 is provided at one end of the upper bearing 1. Correspondingly, a positioning seat 9 is provided on the lower bearing 2. A fixing groove 10 corresponding to the fixing block 8 is provided on the positioning seat 9. The fixing block 8 of the upper bearing 1 is inserted into the fixing groove 10 to achieve the preliminary fixation of the upper and lower bearings 2.

[0030] On both sides of the positioning seat 9 of the lower bearing 2, hinge seats 11 are respectively provided. An arc-shaped plate 12 is hingedly provided on the hinge seat 11. The shape of the arc-shaped plate 12 is adapted to the housing 7 of the upper bearing 1. The arc-shaped plate 12 is connected to the hinge seat 11 through a hinge shaft 13, and a torsion spring 14 is provided on the hinge shaft 13.

[0031] As described above, when the upper bearing 1 is transported to correspond to the lower bearing 2 and the fixing block 8 is inserted into the positioning seat 9 to achieve the preliminary fixation of the upper and lower bearings 2. At the same time, during the downward movement of the upper bearing 1, the upper bearing 1 presses the arc-shaped plate 12, causing the arc-shaped plate 12 to rotate. Finally, when the ends of the upper and lower bearings 2 are in contact, the arc-shaped plate 12 rotates to abut against the upper bearing 1 correspondingly. At this time, the end of the arc-shaped plate 12 is inserted between the nut 4 of the fixing bolt 3 and the housing 7 of the upper bearing 1, thus completing the clamping and fixation of the arc-shaped plate 12. At the same time, the torsion spring 14 has a reverse elastic force, which can maintain the support for the upper bearing 1, and with the fixing effect of the fixing bolt 3, the stable connection between the upper bearing 1 and the lower bearing 2 is realized, improving the installation efficiency.

[0032] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
