Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to an axial sliding bearing. Background Art

[0002] In mechanical transmission systems, axial sliding bearings play an important role. They are mainly used to bear axial loads and ensure the smooth operation of mechanical parts.

[0003] In the existing axial sliding bearing design, the bearing cover and the bearing seat are mostly assembled by splicing and assembling multiple sets of threaded rods and hexagonal nuts, that is, the threaded rods are sequentially passed through the corresponding holes of the bearing cover and the bearing seat, and then tightened with hexagonal nuts. The assembly process is relatively cumbersome and it is not convenient to disassemble and repair the bearing later (during the operation of the equipment, the bearing needs to be disassembled to inspect or replace the internal parts of the bearing due to wear, aging or other reasons).

[0004] Therefore, the utility model proposes an axial sliding bearing to solve the above problems. Utility Model Content

[0005] The embodiment of the utility model aims to provide an axial sliding bearing to solve the above-mentioned problem.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An axial sliding bearing comprises a bearing seat, a bearing cover, a bearing shell, an oil cup and a rotating shaft, wherein slots are provided on both sides of the bearing cover, square pieces are provided on both sides of the bearing seat, and both square pieces are provided with clamping pieces that can move along the square pieces toward / away from the bearing seat, and both clamping pieces are provided with clamping blocks that are adapted to the slots; and a disassembly mechanism is also included for making the two clamping pieces move synchronously in the same direction to realize the assembly and separation of the bearing seat and the bearing cover.

[0008] In an optional solution: the disassembly and assembly mechanism includes an internal threaded hole provided on the bearing seat, a threaded column threadedly matched with the internal threaded hole, and a sleeve sleeved on the threaded column and rotatable relative to the threaded column, and a connecting rod is hinged between the two clamping parts and the sleeve.

[0009] In an optional solution: the threaded column is provided with a pin hole, the bearing seat is provided with an anchor pin for being inserted into the pin hole to lock the threaded column, the bearing seat is provided with a magnetic part, and the anchor pin is provided with an iron part for the magnetic part to adsorb to position the anchor pin.

[0010] In an optional solution: the bearing seat is provided with a plurality of insertion holes, the bearing cover is provided with columns corresponding to and matching the insertion holes one by one, each of the insertion holes is provided with a spring, and the bearing seat is provided with a bolt knob at each insertion hole.

[0011] In an optional solution: the card slot is a wedge-shaped slot, and the card block is a wedge-shaped card block adapted to the card slot.

[0012] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0013] The bearing seat and the bearing cover are assembled by means of card-fitting. The disassembly and assembly mechanism enables the two card-fitting parts to move synchronously in the same direction, that is, the card block is inserted into the corresponding card slot or the card block is disengaged from the corresponding card slot, thereby realizing the rapid assembly and separation of the bearing seat and the bearing cover. The operation is simple, which greatly improves the convenience of later disassembly, assembly and maintenance of the bearing.

DETAILED DESCRIPTION

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] See also Figure 1 and Figure 2 , an axial sliding bearing, including a bearing seat 1, a bearing cover 2, a bearing shell, an oil cup and a rotating shaft 3, wherein both sides of the bearing cover 2 are provided with a slot 4, both sides of the bearing seat 1 are provided with a square piece 7, and the two square pieces 7 are provided with a clamping piece 6 that can move along the square piece 7 toward / away from the bearing seat 1, and the two clamping pieces 6 are provided with a clamping block 5 adapted to the slot 4; and also includes a disassembly mechanism for making the two clamping pieces 6 move synchronously in the same direction to realize the assembly and separation of the bearing seat 1 and the bearing cover 2.

[0026] The bearing seat 1 and the bearing cover 2 are assembled by means of a clamping mechanism, and the two clamping parts 6 are moved synchronously in the same direction (it should be noted that the "same direction" means that the two clamping parts 6 move away from or towards the bearing seat 1) through the disassembly and assembly mechanism, that is, the clamping block 5 is clamped into the corresponding clamping groove 4 or the clamping block 5 is disengaged from the corresponding clamping groove 4, thereby realizing the rapid assembly and separation of the bearing seat 1 and the bearing cover 2, which is simple to operate and greatly improves the convenience of later disassembly, assembly and maintenance of the bearing.

[0027] See also Figure 1 , Figure 3 to Figure 5In one embodiment of the utility model, the disassembly mechanism includes an internal threaded hole 9 provided on the bearing seat 1, a threaded column 10 threadedly matched with the internal threaded hole 9, and a sleeve 15 sleeved on the threaded column 10 and rotatable relative to the threaded column 10, and a connecting rod 8 is hinged between the two clamping parts 6 and the sleeve 15;

[0028] The threaded column 10 is provided with a pin hole 16, the bearing seat 1 is provided with an anchor pin 18 for being inserted into the pin hole 16 to lock the threaded column 10, the bearing seat 1 is provided with a magnetic piece 17, and the anchor pin 18 is provided with an iron piece 19 for the magnetic piece 17 to adsorb to position the anchor pin 18.

[0029] In this embodiment, the threaded column 10 is rotated to move along the channel of the internal threaded hole 9, which drives the sleeve 15 to move accordingly. Under the pulling / pushing action of the two connecting rods 8, the sleeve 15 moves so that the two clamping parts 6 move synchronously in the same direction, thereby realizing the rapid assembly and separation of the bearing seat 1 and the bearing cover 2. When the bearing seat 1 and the bearing cover 2 are assembled, the threaded column 10 is rotated until one end thereof located in the internal threaded hole 9 touches the bottom of the internal threaded hole 9. At this time, it means that the bearing seat 1 and the bearing cover 2 are assembled in place, and then the anchor pin 18 is inserted, and the end of the anchor pin 18 is pinned into the pin hole 16 to lock the threaded column 10.

[0030] See also Figure 1 and Figure 6 In one embodiment of the utility model, the bearing seat 1 is provided with a plurality of insertion holes 12, the bearing cover 2 is provided with columns 11 corresponding to and matching the insertion holes 12, each of the insertion holes 12 is provided with a spring 13, and the bearing seat 1 is provided with a bolt knob 14 at each insertion hole 12;

[0031] The clamping slot 4 is a wedge-shaped slot, and the clamping block 5 is a wedge-shaped clamping block adapted to the clamping slot 4 .

[0032] In this embodiment, when the bearing seat 1 and the bearing cover 2 are assembled, the columns 11 on the bearing cover 2 are respectively inserted into the corresponding insertion holes 12. At this time, under the action of the spring 13, there is a certain distance between the bearing cover 2 and the bearing seat 1. As the block 5 is gradually inserted into the slot 4, the bearing cover 2 gradually approaches the bearing seat 1. When the block 5 is completely inserted into the slot 4, the bearing cover 2 is just tightly against the bearing seat 1. Then, the bolt knob 14 is rotated in turn to make its end tightly against the corresponding column 11, thereby playing the effect of reinforcing the assembly of the bearing seat 1 and the bearing cover 2. When the bearing cover 2 loses its restriction, it bounces up under the action of the spring 13, so that the bearing seat 1 and the bearing cover 2 can be quickly disassembled.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
