Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bearings, and in particular relates to an automobile bearing sealing structure. Background Art
[0002] Bearings are a crucial component in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Bearings require sealing to prevent dust from affecting their rotational accuracy and to minimize the loss of lubricant.
[0003] Currently, bearings are sealed mainly by installing a rubber ring between the inner and outer rings on both sides of the bearing to achieve sealing protection for the bearing. Although the rubber ring of the above structure can achieve sealing of the bearing during use, it cannot help the bearing to dissipate heat efficiently, which can easily cause the bearing to be damaged due to untimely heat dissipation during long-term use. Utility Model Content
[0004] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide an automobile bearing sealing structure.
[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:
[0006] An automobile bearing sealing structure includes an inner ring and an outer ring, wherein both the inner ring and the outer ring are provided with a ball path, wherein rolling balls are placed in the ball path, and the rolling balls are mounted with a retaining frame;
[0007] The inner ring and the outer ring are provided with buckle grooves on both sides of the ball lane, and the buckle grooves are arranged obliquely outward. A rubber sealing ring is installed in the buckle groove, and the width of the rubber sealing ring matches the distance between the inner ring and the outer ring. An outer metal ring is installed on the outer side of the rubber sealing ring, and an inner metal ring is installed on the inner side of the rubber sealing ring. The inner metal ring is threadedly connected with a locking screw, and the locking screw passes through the rubber sealing ring and the outer metal ring. The contact surface between the rubber sealing ring and the inner metal ring is an inclined surface.
[0008] It is further defined that all edges and corners of the rubber sealing ring are rounded, and such a design has a good fitting effect and is smoother.
[0009] It is further defined that the edges of the contact surfaces between the inner metal ring and the rubber sealing ring are rounded, and such a design is not easy to damage the rubber sealing ring.
[0010] It is further defined that there are no less than four locking screws connecting the outer metal ring and the inner metal ring, which are evenly arranged on the outer metal ring and the inner metal ring. Such a design ensures the pulling effect on the inner metal ring.
[0011] It is further defined that the outer metal ring and the inner metal ring are both made of materials with good thermal conductivity. Such a design is conducive to heat conduction and heat dissipation.
[0012] The beneficial effects of adopting the utility model are:
[0013] With the structural design of the utility model, the rubber sealing ring is installed in a limited position under the effect of the buckle groove, and the rubber sealing ring achieves the effect of sealing protection to prevent oil leakage;
[0014] With the structural design of the utility model, rotating the locking screw can pull the inner metal ring to move, thereby causing the inner metal ring to contact the rubber sealing ring, and then causing the rubber sealing ring to move to both sides, thereby increasing the contact force, thereby reducing the gap and enhancing the sealing effect;
[0015] With the structural design of the utility model, heat is effectively transferred to the outer metal ring under the heat conduction of the inner metal ring and the locking screw, thereby enhancing the heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0023] like Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention is an automobile bearing sealing structure, comprising an inner ring 1 and an outer ring 2, wherein both the inner ring 1 and the outer ring 2 are provided with a ball track 3, wherein balls 4 are placed in the ball track 3, and the balls 4 are mounted with a retainer 5;
[0024] The inner ring 1 and the outer ring 2 are provided with buckle grooves 6 on both sides of the ball track 3. The buckle grooves 6 are set obliquely outward. A rubber sealing ring 7 is installed in the buckle groove 6. The width of the rubber sealing ring 7 matches the distance between the inner ring 1 and the outer ring 2. An outer metal ring 8 is installed on the outer side of the rubber sealing ring 7, and an inner metal ring 9 is installed on the inner side of the rubber sealing ring 7. The inner metal ring 9 is threadedly connected with a locking screw 10. The locking screw 10 passes through the rubber sealing ring 7 and the outer metal ring 8. The contact surface between the rubber sealing ring 7 and the inner metal ring 9 is an inclined surface.
[0025] In this embodiment, when using an automobile bearing sealing structure, the inner metal ring 9 and the outer metal ring 8 are first installed on the inner and outer sides of the rubber sealing ring 7 with the locking screws 10. It should be noted that the locking screws 10 do not need to be locked at this time; then, the rubber sealing ring 7 is pressed between the inner ring 1 and the outer ring 2. When pressed at the position of the buckle groove 6, the rubber sealing ring 7 is embedded in the buckle groove 6 and the position is fixed. Then, after adding lubricating oil to the ball channel 3, the other side is sealed with the rubber sealing ring 7 in the same way;
[0026] Adjust the locking screw 10 so that the inner metal ring 9 squeezes the rubber sealing ring 7. Under the premise of ensuring that the rotation of the inner ring 1 and the outer ring 2 is not affected, the oil can be changed without leakage. Therefore, the installation of the locking screw 10 can also achieve the purpose of adjusting the tightness.
[0027] Preferably, all edges and corners of the rubber sealing ring 7 are rounded. Such a design has a good fitting effect and is smoother. In fact, the size of the rounded corners can also be considered according to specific circumstances.
[0028] Preferably, the edges of the contact surfaces between the inner metal ring 9 and the rubber sealing ring 7 are rounded. This design is less likely to damage the rubber sealing ring 7. In fact, the size of the rounded corners can also be considered according to specific circumstances.
[0029] It is preferred that there are no less than four locking screws 10 connecting the outer metal ring 8 and the inner metal ring 9, which are evenly arranged on the outer metal ring 8 and the inner metal ring 9. Such a design ensures the pulling effect on the inner metal ring 9. In fact, the number of locking screws 10 can also be considered according to specific circumstances.
[0030] Preferably, both the outer metal ring 8 and the inner metal ring 9 are made of materials with good thermal conductivity. Such a design is conducive to heat conduction and heat dissipation. In fact, the material selection of the outer metal ring 8 and the inner metal ring 9 can also be considered according to specific circumstances.
[0031] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
