Roller Chain for Digital Printing Presses
Roller chains are one of the most important components in digital printing presses. They are used to drive the printing plate cylinders and transfer rollers that apply ink to the paper. These chains need to be precise, durable, and reliable to ensure that the printing press operates at maximum efficiency.
What is Roller Chain?
A roller chain is a type of chain consisting of interconnected roller links. Each roller link consists of a pin and bush on which a roller rotates.
Roller Chain Design for Digital Printing Presses
The design of roller chains for digital printing presses is critical. These chains must be capable of very high speeds and still maintain precise control over the position and velocity of the printing plate cylinders and transfer rollers. They must also be durable and reliable, as any failure could cause significant downtime and loss of production.
Material Selection
The materials used in the construction of roller chains for digital printing presses are carefully chosen to ensure maximum durability and reliability. High-quality steel alloys are commonly used, along with advanced coatings and lubricants to reduce wear and extend the life of the chain.
Chain Pitch and Roller Diameter
The pitch of the chain and the diameter of the rollers are critical parameters that must be carefully chosen to meet the requirements of the digital printing press. Increasing the pitch increases the strength of the chain, but also increases the size and weight of the chain. Smaller rollers can reduce the size and weight of the chain, but may not provide the necessary durability and reliability.
Sprocket Teeth Profile
The shape of the teeth on the sprockets used with roller chains for digital printing presses is also important. The teeth must be precisely shaped to ensure smooth engagement and prevent wear on the chain and sprocket. Advanced computer modeling and manufacturing techniques are used to create sprockets with optimal tooth profiles.
Applications of Roller Chain in Digital Printing Presses
Roller chains are used in a variety of applications in digital printing presses. They are used to drive the printing plate cylinders and transfer rollers, as well as to control the tension of the web as it passes through the press. They are also used in the automatic register control systems that ensure precise alignment of the printed images on the paper.

Q&A
Q: What are some common causes of roller chain failure?
A: Roller chain failure can be caused by a variety of factors, including inadequate lubrication, wear or damage to the chain or sprockets, or misalignment of the chain or sprockets. Regular maintenance and inspection can help prevent chain failure.
Q: How do I determine the appropriate chain pitch for my digital printing press?
A: The appropriate chain pitch for a digital printing press depends on a number of factors, including the speed and torque requirements of the press, the size and weight of the chain, and the diameter and shape of the sprockets. Consulting with a knowledgeable supplier can help ensure that the appropriate chain pitch is selected.
Q: Can roller chains be used in wet or corrosive environments?
A: Yes, roller chains can be designed for use in wet or corrosive environments. Special coatings and materials can be used to protect the chain from corrosion and extend its life in these harsh operating conditions.
