Description

Technical Field

[0001] This invention relates to the field of bearing technology, and in particular to a bearing for a quartz sand processing equipment. Background Technology

[0002] In the field of quartz sand processing, various processing equipment is involved, such as mills, grinding mills, crushers, and sand making machines. These machines play a crucial role in the production of quartz sand. As an important raw material for many industries such as glass, casting, ceramics, and fireproofing materials, the processing of quartz sand requires crushing and grinding operations to obtain particle size and purity that meet the needs of different industries. Among these processing equipment, bearings are one of the core components, undertaking the key functions of supporting the rotating body of the machinery, reducing the coefficient of friction during the movement of the equipment, and ensuring rotational accuracy. To ensure the smooth operation of such equipment, it is necessary to frequently add lubricating oil to the bearings to reduce wear.

[0003] However, there are some shortcomings in the current bearing design for quartz sand processing equipment: First, to ensure the sealing performance of the bearing during use, sealing rings are usually installed at both ends of the bearing. However, the presence of the sealing rings makes it extremely inconvenient to add lubricating oil to the bearing later. The sealing rings must be removed before the lubricating oil can be added. Frequent removal of the sealing rings can also easily damage the sealing structure, thereby affecting the overall sealing performance of the bearing. Secondly, the inner ring of a bearing is usually used in conjunction with accessories. When dealing with accessories with unequal hole structures, compatibility issues can easily arise between the bearing and the accessory. In such cases, it is often necessary to replace the bearing with one of different specifications, which undoubtedly increases the cost of bearing use. Summary of the Invention

[0004] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide a bearing for quartz sand processing equipment that improves the convenience of lubricating the bearing without affecting its sealing performance. By providing replaceable connectors, the bearing can be adapted to different accessories, thereby improving its compatibility.

[0005] In a first aspect, the present invention provides a bearing for a quartz sand processing equipment, specifically comprising: an inner ring; an arc-shaped structure at the outer end of the inner ring, and side grooves at both ends of the inner ring, wherein a connector is inserted into each set of side grooves, the outer end of the connector is provided with an arc-shaped structure, and a circular hole is opened inside the connector; a retainer is fitted onto the outer end of the inner ring, wherein the lower surface of the ball inside the retainer can move in contact with the arc-shaped structure on the outer side of the inner ring and the connector; and an outer ring is provided at the outer end of the inner ring, wherein an arc-shaped structure is provided on the inner side of the outer ring, and the arc-shaped structure is in contact with the upper surface of the ball.

[0006] Preferably, each set of side grooves has mating grooves A on both sides of the bottom and a through-type mating groove B at the top.

[0007] Preferably, the upper end of the connector is provided with a top block, which can be inserted into the mating groove B. The lower ends of both sides of the connector are symmetrically provided with side blocks, which are inserted into the mating groove A. The inner ring and the bottom of the outer side of the connector are provided with a connected sealing groove A, and the middle position of the inner ring and the outer side of the connector is provided with a connected arc-shaped groove.

[0008] Preferably, the inner side of the cage is provided with mounting grooves at equal intervals, and each set of mounting grooves is fitted with rotatable balls.

[0009] Preferably, sealing grooves B are provided at the upper and lower ends of the inner side of the outer ring.

[0010] Preferably, a connecting groove is provided on the inner side of the outer ring, and an inner hole penetrating the inner side of the outer ring is provided at equal intervals at the upper end of the connecting groove, and an outer hole penetrating the outer end of the outer ring is provided at the lower end of the connecting groove, with a maximum of two sets of outer holes.

[0011] Preferably, a flange is provided at the lower outer end of the outer ring, the flange is located below the outer hole, and fixing holes are provided at equal intervals on the inner side of the flange.

[0012] Preferably, the outer ring is fitted with a washer that can cover the outer hole, and the lower end of the washer contacts the flange. The lower end of the washer is provided with a number of insertion rods equal to the number of fixing holes, and the insertion rods are inserted into the fixing holes.

[0013] Preferably, a first sealing ring is provided at the upper inner side of the outer ring, and the first sealing ring is fitted with the arc groove on the inner ring and the connector. The groove at the outer end of the first sealing ring is staggered with the sealing groove B at the upper end of the outer ring. A second sealing ring is provided at the lower inner side of the outer ring, and the grooves on both sides of the second sealing ring are staggered with the sealing groove B at the lower end of the outer ring and the sealing groove A on the bottom side of the inner ring and the connector.

[0014] 1. In this invention, by inserting a connector with a circular hole into the inner ring side groove, when dealing with accessories with different hole sizes, it is only necessary to replace the connector with one that fits the circular hole to achieve connection with other accessories with different hole sizes in the equipment. This greatly improves the versatility of the bearing and reduces the usage cost caused by replacing bearings of different specifications.

[0015] 2. In this invention, by opening a connecting groove on the inner side of the outer ring and setting an inner hole and an outer hole, when lubricating and maintaining the bearing, it is only necessary to flip the washer and inject lubricating oil into the outer hole. The lubricating oil can then flow out from the inner hole through the connecting groove, achieving uniform lubrication of the bearing interior. This eliminates the need to disassemble the sealing ring, avoiding damage to the sealing structure caused by frequent disassembly of the sealing ring and extending the service life of the sealing ring. At the same time, the concealed outer hole is covered by the washer, which can effectively prevent dust and other debris from entering, ensuring the sealing performance of the bearing interior and maintaining a good operating environment for the bearing. In addition, the staggered interlocking of sealing grooves A and B with the first sealing ring and the second sealing ring further enhances the overall sealing performance of the bearing, providing double protection for the stable operation of the bearing.
