Description

Technical Field

[0001] The invention relates to the technical field of dustproof bearings, in particular to a multifunctional dustproof bearing. Background Art

[0002] Dustproof bearings are bearings with dustproof function, which are mainly used to prevent dust and other impurities from entering the bearing, thereby protecting the normal operation of the bearing and extending its service life. Dustproof bearings are usually equipped with dust covers or sealing rings on one or both sides of the bearing to prevent foreign matter from entering the bearing.

[0003] Patent application number CN202110398652.5 discloses a dustproof bearing comprising an inner ring, an outer ring defining a bearing space with the inner ring, a rolling element located in the bearing space, and two dustproof inner sleeves and two dustproof outer sleeves disposed in the bearing space and on either axial side of the rolling element. Each dustproof inner sleeve comprises a metal ring fixed to one of the inner and outer rings, and a film connected to the metal ring and slidably pressed against the other of the inner and outer rings. Each dustproof outer sleeve comprises a metal shell and a seal slidably pressed against one of the inner and outer rings. The metal shell is fixed to the other of the inner and outer rings and extends radially to have a throttling end for the seal to be disposed. The throttling end and one of the inner and outer rings define two first throttling gaps located on either axial side of the seal. This improves the overall structural strength and maintains a better sealing effect.

[0004] When existing equipment is in use, in order to ensure the dust-proof performance of the bearing, dust-proof gaskets are usually installed at both axial ends of the ball to prevent external dust from invading the interior of the bearing through physical barriers. Although this design can prevent external dust from invading the interior of the bearing, the existence of the dust-proof structure causes the heat dissipation efficiency of the bearing to be greatly reduced during operation. At the same time, during the bearing lubrication process, the roller area is difficult to fully obtain the infiltration of lubricating oil, which affects the lubrication effect and is not conducive to the stable operation of the equipment. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a multifunctional dustproof bearing to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a multifunctional dustproof bearing, comprising an inner ring, wherein the outer wall of the inner ring is fixedly connected to a hollow column, the outer wall of the hollow column is provided with a limiting groove, the outer side of the limiting groove is provided with a ball, the outer wall of the hollow column is provided with an annular groove, the inner wall of the annular groove is rotatably connected to a dustproof mechanism, and further comprising:

[0008] According to the above technical solution, an annular cavity is provided on the inner wall of the hollow column one, and a through hole one is provided at both the upper and lower ends of the hollow column one, and the through hole one penetrates the hollow column one and extends to the inner wall of the annular cavity, and a through hole two is provided on the outer wall of the limiting groove one, and the through hole two penetrates the limiting groove one and extends to the inner wall of the annular cavity. The annular cavity is used to store lubricating oil, and the through hole one and the through hole two are used for the flow of lubricating oil. By setting the annular cavity, the equipment has the ability to store a certain amount of lubricating oil, and the bearing can store a certain amount of lubricating oil when it is not working. When the bearing enters the operation stage, the lubricating oil stored in the cavity can be transported to the ball area, providing stable oil film protection to the ball, thereby improving the wear resistance and heat dissipation efficiency of the bearing.

[0011] According to the above technical solution, an arc groove 1 is provided on the side of the annular plate away from the annular groove 3, and the arc groove 1 passes through the annular plate and extends to the side of the annular plate away from the annular cavity. A heat dissipation groove is provided on the side of the annular plate away from the annular groove 3, and the heat dissipation groove facilitates the device to transfer the temperature of the internal ball 1 to the outside of the device.

By setting the auxiliary component, when the equipment needs to lubricate the bearing, the angle of the auxiliary component can be rotated so that the external lubricating oil can be injected into the outer peripheral area of ​​the ball 1 through the arc groove 1 and the arc groove 2. On the premise of maintaining the original dustproof function of the bearing, it is ensured that the ball can be fully infiltrated with lubricating oil, thereby ensuring the stability of the equipment operation.

[0014] According to the above technical solution, a connecting ring is fixedly connected to the side of the sliding ring away from the annular plate, and a baffle is fixedly connected to the inner wall of the connecting ring. The position of the baffle can be changed as the sliding ring rotates.

[0015] Compared with the prior art, the present invention provides a multifunctional dust-proof bearing with the following beneficial effects:

[0016] 1. The present invention provides an auxiliary component. When the equipment needs to lubricate the bearing, the angle of the auxiliary component can be rotated so that external lubricating oil can be injected into the outer peripheral area of ​​ball 1 through arc groove 1 and arc groove 2. While maintaining the original dustproof function of the bearing, it ensures that the ball can be fully infiltrated with lubricating oil, thereby ensuring the stability of equipment operation.

[0018] 3. The present invention provides a dustproof mechanism, which protects external dust from entering the interior of the bearing. At the same time, a plurality of heat dissipation grooves are provided inside the mechanism. When the bearing generates heat during operation, the heat can be transferred to the outside of the equipment through the heat dissipation grooves. The dustproof mechanism improves the problem of poor heat dissipation of the bearing while maintaining the dustproof performance, thereby improving the stability of the bearing operation.

[0019] 4. The present invention sets an external mechanism. As the outer ring rotates, the inclined grooves on its surface will rotate. During the rotation process, it can induce air vortexes, prompting the airflow to flow along the outside of the bearing. This airflow can take away the heat generated by the operation of the bearing, thereby effectively reducing the operating temperature of the bearing, improving the heat dissipation efficiency, and improving the stability of the bearing during long-term operation.
