Abstract

The invention relates to a double-pitch double-pin shaft heavy-duty conveyor chain, which is assembled by connecting and assembling several chain link units. Both the inner chain plate and the guide plate are arranged on the inner side of the outer chain plate, and the guide plate cooperates with the guide groove on the sprocket to limit the lateral movement of the conveyor chain; the pin group includes short pins that can roll relatively Shaft and long pin shaft; the inner chain plate and guide plate are stacked and installed, and a first shaft hole passing through the inner chain plate and guide plate is provided; the short pin shaft and long pin shaft both pass through the first shaft hole, and the short pin shaft is restricted from rotating in the circumferential direction of the first shaft hole; both ends of the long pin shaft extend into the first shaft hole and are fixedly connected with the outer chain plate, and the two ends of the short pin shaft The part is freely arranged and can move in the axial direction of the first shaft hole. The invention has the advantages of heavy load, small friction and long service life.

Description

technical field

[0001] The invention belongs to the field of mechanical design and manufacture and chain transmission, and is suitable for smooth conveying on various conveying lines, especially a double-pitch double-pin heavy-duty conveying chain with low noise and low friction, which is suitable for conveying glass Products, ceramics, medical equipment, electronic components, automobiles and other fields. Background technique

[0002] The toothed chain is an important mechanical basic part with a wide range of applications. Due to the characteristics of low noise, high reliability and high motion precision, the toothed chain has been widely used in recent years, especially in various automatic production lines, playing an irreplaceable role with its unique advantages. Its transmission form is superior to toothed belt transmission, gear transmission and roller chain transmission. The traditional standard toothed chain is that each chain plate has a single-pitch double-too...
