| Universal Joint Drive |
Suitable for cold roll forming machines where two shafts intersect, have large angular deviation, or variable spacing. Used to connect components with different axes, such as the connection between the feeding mechanism and the roll drive shaft. |
General, suitable for the production of ordinary cold-formed products with no extremely high precision requirements. |
Low, mainly involving regular inspection of lubrication and universal joint wear. |
Medium, usually around 85% – 92%. |
Relatively simple with few components. |
Low, with no high cost for basic components. |
Good, can work in environments with a certain amount of dust and oil contamination. |
| Gear Drive |
Cold roll forming machines requiring strict transmission precision, high precision specifications for cold-formed products, large power transmission, and compact structure, such as high-precision cold-formed thin-walled tube production equipment. |
High, can achieve accurate transmission ratio, ensure precise roll speed, and improve product dimensional accuracy. |
High, requiring continuous good lubrication; replacement cost is high when gears are worn. |
High, up to 95% – 98%. |
Relatively complex, consisting of multiple components such as gears, shafting, and a gearbox. |
High, with high requirements for gear manufacturing and installation precision, leading to high costs. |
Poor, has high requirements for environmental cleanliness and lubrication conditions; dusty and humid environments can easily accelerate wear. |
| Gear-Chain Drive |
Suitable for occasions with large shaft spacing, certain precision requirements, and the need to adapt to harsh environments, such as some large cold roll forming units or factory workshops with poor environments. |
High, with accurate transmission ratio, but chain wear will affect precision. |
Medium to high, chains require regular lubrication and replacement to prevent chain jumping and disengagement; more complex to maintain than pure gear drive. |
High, approximately 92% – 96%. |
Medium, combining gear and chain structures. |
Medium, chain cost is low, but the gear part still has a certain cost, resulting in moderate overall cost. |
Good, can be used in high-temperature, dusty, low-speed, and heavy-load environments. |
