7. MANIPULATION OF CHAINS You’ve made your selection, ordered the chain, and it arrives. Now what? In this chapter, we will review how to get started. Specifically, we will discuss installing chain on the equipment; checking the accuracy of the installation; and testing, inspecting, and lubricating for start-up. The guidelines in this chapter will get you started, but refer to your specific manufacturer’s catalog for details.
7.1 TRANSMISSION CHAINS, SMALL PITCH CONVEYOR CHAINS
7.1.1 Installation Most transmission chains are sold in standard lengths, usually 3,048 mm (10 ft). The length may vary, depending on the size of the chain. Small pitch conveyor chains may be special ordered in lengths of chain as required. The first thing you must do is cut the chain to the length you need.
Tools: Angle grinder (to cut the riveted parts), chain vise, punch, hammer, chain screw.
Method Step 1. Grind the riveted portion of the two pins with the angle grinder. If the chain has cottered pins, remove them. Step 2. Secure the chain in the chain vise. Using the primary punch and the secondary punch (or the chain screw), remove one set of pins. Step 3. Install both ends of the chain onto sprockets and join with connecting links (Figure 7.1). Be sure to install the clips or cotter pins as shown in Figures 7.2 and 7.3.
