Chain / Precision Industrial Roller Chain / Transmission Chain

 

1. Dimensional Parameters
   • Pitch: It refers to the distance between the centers of two adjacent rollers and is a fundamental dimensional parameter of the chain. Common pitches include 6.35mm, 9.525mm, 12.7mm, etc. The smaller the pitch, the smoother the chain runs, making it suitable for high-speed and light-load applications; the larger the pitch, the stronger the load-bearing capacity, which is suitable for low-speed and heavy-load situations.
   • Number of Chain Links: The chain is composed of multiple chain links, and the number of chain links is usually an even number to ensure that the connection methods at both ends of the chain are the same. According to different actual application scenarios, the number of chain links can be flexibly selected, generally ranging from dozens to hundreds.
   • Roller Diameter: The rollers are key components for the meshing of the chain and the sprocket, and the size of their diameter affects the load-bearing capacity and transmission efficiency of the chain. Generally speaking, the larger the roller diameter, the greater the load that the chain can bear, and at the same time, the contact area with the sprocket is larger, and the transmission efficiency is higher.
2. Material Characteristics
   • Chain Plates: Usually made of high-quality carbon steel or alloy steel, such as 40Cr, 20MnV, etc. After heat treatment processes such as quenching and tempering, these materials have high strength and toughness, and can withstand the tensile, bending and impact loads of the chain during the transmission process.
   • Rollers: Generally, high-strength alloy steel is selected, such as GCr15 bearing steel. After precision machining and heat treatment, the surface has high hardness and good wear resistance, and can maintain good meshing with the sprocket at high speed, reducing wear and noise.
   • Pins: The material is similar to that of the rollers, mostly high-quality alloy steel, and it is required to have high hardness and shear strength to ensure that the connection between the pins, chain plates and rollers is firm and reliable when the chain transmits power, and it is not easy to deform and break.
3. Manufacturing Precision
   • Dimensional Accuracy: The precision industrial roller chain has extremely high requirements for the dimensional accuracy of each component. The dimensional tolerances of the thickness and hole diameter of the chain plate, the diameter and cylindricity of the roller, the diameter and straightness of the pin, etc. are all controlled within a very small range, generally between ±0.01mm and ±0.05mm, to ensure a good fit between the chain and the sprocket and reduce transmission errors.
   • Geometric Tolerance: In addition to dimensional accuracy, the geometric tolerance of the chain also has strict requirements, such as the flatness of the chain plate, the circular runout of the roller, the perpendicularity of the pin, etc. The control of these tolerances helps to ensure the smoothness and reliability of the chain during operation and reduce vibration and noise.
4. Mechanical Properties
   • Tensile Strength: It is an important indicator to measure the load-bearing capacity of the chain. According to different specifications and models of the chain, its tensile strength generally ranges from several thousand Newtons to several hundred thousand Newtons. For example, for a single-row precision industrial roller chain with a pitch of 12.7mm, its tensile strength is usually around 20kN to 30kN.
   • Fatigue Strength: Since the chain bears periodic loads during the working process, fatigue strength is one of its important performance indicators. Through optimizing materials, improving manufacturing processes and surface treatments, precision industrial roller chains have high fatigue strength, can maintain good performance during long-term operation, and are not prone to fatigue fracture.
   • Wear Resistance: The wear resistance of the chain directly affects its service life. Precision industrial roller chains improve the surface hardness and wear resistance of each component of the chain through the use of high-quality materials and advanced surface treatment processes, such as hard chromium plating, nitriding, etc., so that they can maintain good performance under high-speed and heavy-load working conditions.
