Description

Technical Field

[0001] The utility model relates to the technical field of mechanical bearings, in particular to a mechanical bearing device for construction engineering. Background Art

[0002] With the development of the bearing industry, three-point and four-point contact ball bearings have emerged to meet diverse needs. The inner ring of a four-point contact ball bearing is made of two precisely assembled half-rings, with the rolling elements making contact with the inner and outer rings at four points. Four-point contact ball bearings offer excellent radial and axial load-bearing capacity. Three-point contact ball bearings also have a certain axial load capacity, while also offering excellent lubrication and a long service life. The inner rings of standard three- and four-point contact ball bearings are composed of two inner half-rings, which increases the number of rolling elements and thus the load-bearing capacity. Patent No. CN201420675203.6 discloses a bearing device for construction machinery. This device features a fixed connection between the outer bearing housing and the inner ring, eliminating the need for a mating connection between the outer bearing housing and the inner ring, which can result in less precise alignment. This design eliminates the need for mating during operation, saving time. However, during the use of construction machinery bearings, dust can easily infiltrate the bearing through the oil inlet, potentially affecting the steel balls and support rings within the bearing. Therefore, a bearing device for construction machinery is proposed. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a mechanical bearing device for construction engineering.

[0004] The technical solution adopted by the utility model to solve the technical problem is a mechanical bearing device for construction engineering, comprising an inner ring body and an outer ring body, wherein an annular groove is formed on one side of the inner ring body opposite to the outer ring body, and the annular groove is provided in two groups, and a gasket for protection is clamped between the two groups of the annular grooves, and a clamping block is integrally constructed on the outer wall surface of the gasket, and the clamping block is provided in multiple groups, and a sponge ring is bonded to the outer wall surface of the gasket to be clamped with the clamping block;

[0005] The outer peripheral surface of the outer ring is provided with sliding holes, and there are multiple groups of sliding holes. A plug is screwed into the sliding hole, and a sliding plate for support is slidably installed in the sliding hole. A carbon block for lubrication is bonded to the end of the sliding plate away from the plug.

[0006] By adopting the above technical solution, when the mechanical bearings for construction projects are used, the gasket in the annular groove between the inner ring body and the outer ring body can seal and protect the gap between the two, thereby reducing the infiltration of dust and debris therein. At the same time, the gasket can drive the sponge ring to tightly seal the gap, thereby further improving the dustproof effect. At the same time, the multiple sets of clamping blocks can improve the stability of the connection between the gasket and the sponge ring, so that the gasket drives the sponge ring to operate stably without affecting the operation of the mechanical bearing.

[0007] When using mechanical bearings for construction projects, the sliding vanes in the sliding holes on the outer periphery of the outer ring can drive the carbon block to move, and make the carbon block and the steel balls between the outer ring body and the inner ring body abut against each other, which is convenient for auxiliary lubrication and enables the steel balls between the two to operate stably. At the same time, the plugs in the sliding holes are easy to disassemble and assemble, which makes it easy to reduce the separation between the sliding vanes and the sliding holes, so that they can operate stably.

[0008] Specifically, a spring is installed between the plug and the slide to push the slide to slide.

[0009] By adopting the above technical solution, the spring between the plug and the slide facilitates pushing the slide, so that the slide can stably drive the carbon block and the steel balls between the outer ring body and the inner ring body to abut against each other, thereby facilitating lubrication.

[0010] Specifically, four corner holes are opened on the outer wall surface of the plug.

[0011] By adopting the above technical solution, the four-corner holes make it easier to disassemble and assemble the plug.

[0012] Specifically, a rubber ring for preventing leakage is bonded to one end of the plug close to the sliding hole.

[0013] By adopting the above technical solution, the rubber ring facilitates improving the tightness of the plug being screwed into the sliding hole, thereby reducing the infiltration or leakage of dust, debris or oil.

[0014] Specifically, the outer ring body and the inner ring body are both provided with ring grooves on opposite sides, and there are multiple groups of ring grooves. Asbestos paper rings for dust prevention are clamped between two groups of the ring grooves.

[0015] By adopting the above technical solution, the asbestos paper ring is clamped between the multiple groups of ring grooves between the outer ring body and the inner ring body, which is convenient for auxiliary sealing of the gap between the outer ring body and the inner ring body, and at the same time can limit the lubricating oil, so that the lubricating oil added between the outer ring body and the inner ring body can lubricate the steel balls more stably.

[0016] Specifically, the inner circumference of the asbestos paper ring is equipped with a ring sheet for improving strength.

[0017] By adopting the above technical solution, the ring piece can improve the strength of the asbestos paper ring, thereby reducing the deformation of the asbestos paper ring.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The technical solution of the present application, through the design of ring grooves, washers, blocks and sponge rings, when used in mechanical bearings for construction projects, the washers in the ring grooves between the inner ring body and the outer ring body can seal and protect the gap between the two, thereby reducing the infiltration of dust and debris therein. At the same time, the washers can drive the sponge rings to tightly seal the gaps, thereby further improving the dustproof effect. At the same time, multiple sets of blocks can improve the stability of the washers and sponge rings after they are connected, so that the washers drive the sponge rings to operate stably without affecting the operation of the mechanical bearings.

[0020] 2. The technical solution of this application is designed with sliding holes, plugs, sliding plates and carbon blocks. When the mechanical bearings are used in construction projects, the sliding plates in the sliding holes on the outer periphery of the outer ring can drive the carbon blocks to move, and make the carbon blocks and the steel balls between the outer ring body and the inner ring body abut against each other, which is convenient for auxiliary lubrication and enables the steel balls between the two to operate stably. At the same time, the plugs in the sliding holes are easy to disassemble and assemble, which makes it easy to reduce the separation between the sliding plates and the sliding holes, so that they can operate stably.
