Description

Technical Field

[0001] The utility model relates to the field of industrial bearing installation equipment, in particular to a sliding bearing seat. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is often called the bearing seat. The installation of existing self-lubricating dynamic bearings is very laborious, and often requires hammering before they can be installed into the bearing seat. As time goes by, the bearing will shift, thus affecting the precision of the entire device. Poor assembly accuracy can easily cause inadequate installation.

[0003] According to the authorization announcement number CN 215861387 U, a sliding bearing seat is disclosed, including a bearing seat composed of a base and a bearing cover above the base, a bearing is clamped in the bearing seat cavity, a bearing sleeve is penetrated through the inner ring of the bearing, a fixed shell is sleeved on the bearing sleeve, the fixed shell is located at one end of the bearing, a retaining spring is also sleeved on the bearing sleeve, the retaining spring is located between the fixed shell and the bearing, a retaining plate is provided on the inner side wall of the retaining spring, and is arranged corresponding to the recessed part of the bearing sleeve to form a snap structure, a baffle is provided on the outer side wall of the retaining spring, and a plurality of baffles are equidistantly arranged along the circumferential direction of the retaining spring; the utility model first clamps the bearing sleeve on the inner ring of the bearing to reduce the friction between the inner ring of the bearing and the main shaft, and drives the locking retaining spring to lock the bearing position by adjusting the fixed shell to fix it, thereby greatly improving the accuracy of the entire device.

[0004] The above patent still has some problems during use. If the bearing housing is locked only by a locking spring, the housing will become loose during long-term use, which will still cause problems with the bearing installation accuracy and lead to problems in the use of the bearing. Therefore, a sliding bearing seat is now needed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] The utility model provides: a sliding bearing seat, such as Figure 1-Figure 5 As shown, it includes a bearing seat bottom shell 1 and a bearing seat top shell 15 bolted to the bearing seat bottom shell 1, and a bonding layer 14; a first inner groove 2 is opened in the middle of the bearing seat bottom shell 1, and two groups of slots 4 are opened at the top of the two sides of the first inner groove 2, and a shaft ring 5 is clamped and installed inside the first inner groove 2, and a group of limiting arc buckle plates 9 are slidably plugged and installed on the front and back sides of the top of the bearing seat bottom shell 1; a connecting inner plate 16 is installed at the bottom end of the bearing seat top shell 15, and two groups of bonding layers 14 are clamped and installed on one side of the connecting inner plate 16 respectively.

[0024] Preferably, a group of threaded holes 3 are respectively opened in the middle of both ends of the bearing seat bottom shell 1, and the shaft ring 5 is clamped and installed in contact with the inner wall of the first inner groove 2. A group of limit baffles 6 are respectively installed at both ends of the shaft ring 5. An oil inlet groove 7 is opened in the center of the inner wall of the shaft ring 5. Several groups of rollers 8 are rotatably installed on both sides of the inner wall of the shaft ring 5 on the oil inlet groove 7, and the threaded hole 3 opened in the center of the top of the bearing seat bottom shell 1 cooperates with the locking bolt 21 to ensure the connectivity between the bearing seat bottom shell 1 and the bearing seat top shell 15. At the same time, the slots 4 opened on both sides of the threaded hole 3 can ensure the connectivity between the two groups of limit arc buckle plates 9 and the bearing seat bottom shell 1, thereby better limiting the shaft ring 5. The limit baffles 6 installed at both ends of the shaft ring 5 can ensure that the shaft ring 5 will not slide after the bearing seat bottom shell 1 and the bearing seat top shell 15 are connected, and the oil inlet groove 7 opened inside the shaft ring 5 can cooperate with the oil filling pipe 19 to deliver lubricating oil to lubricate the bearing in the working state, thereby ensuring the service life of the bearing and reducing bearing wear.

[0025] Furthermore, a group of plug plates 10 are respectively installed at both ends of the bottom of the limiting arc buckle plate 9, and each group of plug plates 10 is respectively plugged and installed in the corresponding side slot 4. The bottom end surface of the limiting arc buckle plate 9 is installed in contact with the top surface of the bearing seat bottom shell 1. The plug plates 10 installed at the bottom of the limiting arc buckle plate 9 are plugged into the slot 4, which can apply longitudinal pressure to the shaft ring 5. At the same time, the two groups of limiting arc buckle plates 9 can be used to apply downward pulling force to the bearing seat top shell 15, thereby avoiding the problem of loose connection between the bearing seat top shell 15 and the bearing seat bottom shell 1.

[0026] Furthermore, the two groups of limiting arc buckle plates 9 are symmetrically provided with second inner grooves 11 on corresponding sides, the inner arc surface of the limiting arc buckle plate 9 is provided with an anti-skid layer 12, the inner arc surface of the limiting arc buckle plate 9 is located on the outside of the anti-skid layer 12 and a protective arc plate 13 is glued and installed, and the outer arc surface of the limiting arc buckle plate 9 is provided with a bonding layer 14. The anti-skid layer 12 is mainly made of rubber structure, which ensures that the protective arc plate 13 fits the outer arc surface of the shaft ring 5 while reducing damage to the shaft ring 5. At the same time, it can also fit with the inside of the bearing seat top shell 15 through the provided bonding layer 14, thereby reducing the wear of the limiting arc buckle plate 9 during use, and the bonding layer 14 is a polymer wear-resistant coating.

[0027] It is worth mentioning that the inner arc surface of the bearing seat top shell 15 and the connecting inner plate 16 directly form a slot 17, one side of the limiting arc buckle plate 9 is inserted into the slot 17, and one side of the connecting inner plate 16 is correspondingly inserted into the second inner groove 11, and the inner arc surface of the bearing seat top shell 15 is provided with an anti-wear layer 18. The connecting inner plate 16 installed on the inner arc surface of the bearing seat top shell 15 limits the two groups of limiting arc buckle plates 9, so that the two groups of limiting arc buckle plates 9 apply pressure to the connecting inner plate 16 after the insertion is completed. When the bearing seat top shell 15 is loose, the limiting arc buckle plate 9 applies a resistance force to the connecting inner plate 16 to prevent the bearing seat top shell 15 from being separated from the bearing seat bottom shell 1.

[0028] Specifically, an oil filling pipe 19 is installed through the center of the bearing seat top shell 15, and two groups of limit seats 20 are symmetrically installed on both sides of the outer arc surface of the bearing seat top shell 15. A group of locking bolts 21 are installed on the internal threads of each group of limit seats 20, and the ends of the locking bolts 21 are threadedly installed in the threaded holes 3. The oil filling pipe 19 opened in the center of the bearing seat top shell 15 makes it easier to inject lubricating oil into the shaft ring 5 for use, and the set limit seats 20 limit the use of the locking bolts 21, so that the connection between the bearing seat bottom shell 1 and the bearing seat top shell 15 is more stable and firm.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
