Description

Technical Field

[0001] The utility model relates to the technical field of I-shaped wheels, in particular to a new type of I-shaped wheel. Background Art

[0002] An "I-shaped wheel" is a roller of a specific shape, commonly used in suspended conveyor systems in factories and warehouses. Its name comes from its shape similar to the cross-section of an I-beam, so it is called an "I-shaped wheel". As an important mechanical transmission device, the I-shaped wheel is widely used in various industrial fields for functions such as transmitting power, speed regulation and rotation.

[0003] However, the connection parts of welded or riveted I-shaped wheels are prone to fatigue cracks or looseness after long-term use or under high load conditions, which affects the stability and service life of the I-shaped wheels. Aluminum I-shaped wheels are susceptible to vibration and impact and are easily damaged, which reduces the reliability and service life of the I-shaped wheels. Utility Model Content

[0004] In view of the above problems, the utility model provides a new type of I-shaped wheel, which effectively solves the problems that I-shaped wheels made of iron or steel are heavy and not conducive to the installation and operation of equipment, and that aluminum I-shaped wheels are easily affected by vibration and impact and are easily damaged.

[0005] The utility model adopts the following technical solutions:

[0006] A novel I-shaped wheel comprises a cylinder, characterized in that: two identical discs are connected to both sides of the cylinder, one side of each of the two discs is provided with a conical fixed end, six threaded holes are evenly arranged on the conical fixed end, bolts are arranged in the threaded holes, the conical fixed end is connected to the disc through the bolts, a circular through groove is arranged in the conical fixed end, the inner edge of the conical fixed end is an inclined surface, the inclination angle of the inclined surface is 60 degrees and the depth is 29.5mm, the depth of the circular through groove is 38mm, the diameter of the threaded hole is 8mm, the bolts and the conical fixed end are made of stainless steel, and the area between the disc and the cylinder is formed by heating and forging after turning an aluminum rod.

[0007] Furthermore, the disc and the cylinder are made of aluminum.

[0008] Furthermore, the edge of the disc is provided with a chamfer, and the chamfer is 0.5×45°.

[0009] Furthermore, the outer diameter of the cylinder is 220 mm, the height of the cylinder is 200 mm, and the diameter of the center hole of the cylinder is 147 mm.

[0010] Furthermore, the outer diameter of the disc is 260 mm, and the thickness of the disc is 16 mm.

[0011] The advantage of the utility model is that by connecting the same disc on both sides of the cylinder and fastening with bolts using a conical fixed end, the design enhances the structural stability and durability of the entire I-shaped wheel. The use of stainless steel as the manufacturing material for the bolts and the conical fixed end further ensures the corrosion resistance of the product and the strength retention under long-term use. The inner side of the conical fixed end is designed to be an inclined surface with an inclination angle of 60 degrees, which provides a better contact surface and makes the connection part tighter and more precise. This design provides higher stability and load distribution efficiency when subjected to axial and radial loads. The disc and the cylinder are formed by turning and heating aluminum bars, which have the advantages of high density, no pores and high efficiency. The overall structure is made of aluminum, which effectively reduces the overall weight while maintaining good mechanical strength and corrosion resistance. BRIEF DESCRIPTION OF THE DRAWINGS
