Description

Technical Field

[0001] This utility model relates to the field of rubber-coated roller technology, and in particular to a rubber-coated roller with good stability, wear resistance and weather resistance. Background Technology

[0002] Rubber-coated rollers are rollers with a rubber coating on their outer ring. They are common accessories in rolling conveyor systems and play a vital role in various equipment and machinery, improving equipment performance and lifespan, reducing maintenance costs, and providing more reliable operation. Rubber-coated rollers are mainly used as support wheels installed at the bottom of equipment to move equipment. They are characterized by quiet operation and high strength, and are widely used in automated equipment.

[0003] Currently, the rubber-coated rollers on the market have smooth roller frame surfaces. During long-term operation, under the influence of external forces, temperature, and pressure, the rubber coating on the roller body surface is prone to separation, which can cause equipment malfunctions.

[0004] To address the aforementioned issues, a rubber-coated roller with stable wear resistance and good weather resistance is provided based on existing technologies. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem of existing rubber-coated rollers on the market, where the roller frame surface is smooth. During long-term operation, under the influence of external forces, temperature, and pressure, the rubber coating on the roller body surface is prone to separation, causing equipment malfunctions. This invention provides a stable, wear-resistant, and weather-resistant rubber-coated roller to solve the above technical problem. By designing the surface of the roller body as a grid groove structure and casting a ring of polyurethane rubber coating on the outer side of the roller body, the rubber coating is installed by casting. After solidification, the two are firmly bonded together. The outer surface of the bearing outer ring has grid grooves, and the roller body and the rubber coating are not only bonded by adhesive, but also physically interlocked after the rubber coating is cast. This helps increase the stability of the rubber coating and the roller body, thereby effectively increasing the durability of the rubber-coated roller and extending its service life.

[0006] A rubber-coated roller with stable wear resistance and good weather resistance is characterized by: comprising a roller body, wherein the roller body is composed of a bearing and a rubber coating layer, the bearing is composed of an inner ring, an outer ring and balls, the outer wall of the inner ring is provided with a groove A, the inner wall of the outer ring is provided with a groove B, the groove A and the groove B correspond to each other, the inner ring and the outer ring are assembled together by ball sleeves, the outer wall of the outer ring is provided with a grid groove, and the rubber coating layer is installed on the outer wall of the outer ring by casting.

[0007] Furthermore, the A groove surrounds the outer wall of the inner ring, and the B groove surrounds the inner wall of the outer ring.

[0008] Furthermore, the diameters of groove A and groove B are the same, and the diameters of groove A and groove B match the diameter of the ball.

[0009] Furthermore, the material of the coating layer is polyurethane.

[0010] Furthermore, the depth of the mesh groove is less than 1 mm.

[0011] Furthermore, the mesh grooves are evenly distributed around the outer wall of the outer ring.

[0012] Compared with the prior art, the advantages of this utility model include: the rubber coating layer is installed by casting. First, an adhesive is applied to the outer surface of the bearing outer ring, and then the roller body is placed in the mold to cast the heated and melted polyurethane rubber coating material. After solidification, the two are firmly bonded together. The outer surface of the bearing outer ring has a grid groove. The roller body and the rubber coating layer are not only bonded by the adhesive, but also physically interlocked after the rubber coating is cast. This helps to increase the stability of the rubber coating layer and the roller body, thereby effectively increasing the durability of the rubber-coated roller and extending its service life.

[0013] The coating layer is made of polyurethane, a highly polar polymer compound with low affinity for non-polar mineral oils, and is virtually unaffected by fuel oils and machine oils. Polyurethane exhibits outstanding wear resistance, typically ranging from 0.01 to 0.10 cm³ / 1.61 km, approximately 3-5 times that of rubber. This gives the coated rollers high hardness, excellent wear resistance, and high elasticity even at high hardness. It also boasts a smooth surface, superior grease resistance, and good chemical resistance, enabling its use in harsh environments such as high and low temperatures, dryness, and humidity. This increases the durability of the coated rollers, enhancing their wear resistance and corrosion resistance, effectively extending their service life. Attached Figure Description

Figures 1 to 5As shown, the device includes a roller body 1, which is composed of a bearing 2 and a rubber coating layer 3. The bearing 2 is composed of an inner ring 201, an outer ring 202, and balls 203. The outer wall of the inner ring 201 has an A groove 2011, and the inner wall of the outer ring 202 has a B groove 2021. The A groove 2011 and the B groove 2021 correspond to each other. The A groove 2011 surrounds the outer wall of the inner ring 201, and the B groove 2021 surrounds the inner wall of the outer ring 202. The A groove 2011 and the B groove 2021 have the same diameter and depth, and the A groove 2011 and the B groove 2021 are identical. The diameter of 2021 matches the diameter of the ball bearing 203. The inner ring 201 and the outer ring 202 are assembled together by the ball bearing 203. One end of the ball bearing 203 is slidably assembled in groove A 2011, and the other end is slidably assembled in groove B 2021. The bearing 2 can slide smoothly. The outer wall of the outer ring 202 is provided with a grid groove 2022. The rubber coating layer 3 is installed on the outer wall of the outer ring 202 by casting. The material of the rubber coating layer 3 is polyurethane. Polyurethane is a highly polar polymer compound with low affinity for non-polar mineral oils and is almost unaffected by corrosion in fuel oil and machine oil.Meanwhile, the properties of polyurethane adhesives can be adjusted by regulating the ratio of isocyanate and polyol, achieving high adhesion to the substrate, excellent water resistance, oil resistance, and chemical resistance. Polyurethane has good low-temperature performance, making it suitable for applications in cold regions. It also exhibits excellent resistance to high-energy radiation, maintaining satisfactory performance even at radiation doses of 10⁻¹⁰ Gh⁻¹. Polyurethane possesses superior properties such as wear resistance, temperature resistance, sealing, sound insulation, and good processability. Its wear resistance is exceptional, typically ranging from 0.01-0.10 cm³ / 1.61 km, approximately 3-5 times that of rubber, giving coated rollers high hardness, excellent wear resistance, and high elasticity even at high hardness. It also boasts a high surface finish, superior grease resistance, and good chemical resistance, enabling its use in harsh environments such as high and low temperatures, dryness, and humidity, thus increasing the durability of coated rollers. The wear resistance and corrosion resistance of the rubber-coated roller are enhanced, effectively extending its service life. The depth of the grid groove 2022 is less than 1mm, and the grid groove 2022 is evenly distributed around the outer wall of the outer ring 202. The rubber coating is installed by casting. Before casting, an adhesive is applied to the outer surface of the bearing outer ring. Then, the roller body is placed in the mold and heated and melted polyurethane coating material is poured in. After the polyurethane coating material solidifies, the polyurethane coating layer and the roller body are firmly bonded together. The outer surface of the bearing outer ring is designed with a grid groove with a groove depth of less than 1mm. After casting, the roller body and the rubber coating layer are not only bonded by the adhesive, but the polyurethane fills the grid groove. After casting, the rubber coating layer and the roller body are physically interlocked, further strengthening the stability of the rubber coating layer and the roller body, thereby effectively increasing the durability of the rubber-coated roller and extending its service life.
