Specification standard for Taiwan wheel tires: The tire code of the reputation standard, expressed in millimeters as the percentage of cross-sectional width and flatness ratio, followed by the tire type code, wheel rim diameter (inches), load index (allowable load capacity code), and allowable vehicle speed code. For example, in 175/70R14 77H, 175 represents a tire width of 175MM, 70 represents a flatness ratio of 70% of the tire section, that is, the section height is 70% of the width, the wheel rim diameter is 14 inches, the load index is 77, and the vehicle speed is H-class
Performance standards: including tire strength, hardness, elasticity, performance, aging resistance, high-speed performance, braking performance, etc. For example, in terms of performance, platform tires are usually made of excellent rubber materials and processes, which give them good performance and can adapt to different road conditionsPlatform wheel sprocket
Size specifications: For example, the standard sprocket (24A) is a 1.5-inch single row platform wheel sprocket, where "24A", "1.5 inch", "single row", etc. are descriptions of the sprocket size, model, and other specifications.
. Different application scenarios and devices have different requirements for the size, number of teeth, and arrangement of sprockets Material standard: Generally, suitable materials are selected based on the usage environment and performance requirements of the sprocket, such as 45 # steel. After quenching and other treatments, 45 # steel has good strength and performance, which can meet the stress requirements of the sprocket during the transmission process
