Show all Line-shaft Spools Manufacturers

Line-shaft spools are mounted to the drive shaft of a line-shaft conveyor. A belt transmits power from the spool to drive individual conveyor rollers. Line-shaft spools are mounted to a shaft (line-shaft) on conveyors referred to as line-shaft conveyors. In these conveyors, each individual roller is driven by a belt that connects between a groove in the roller and a spool that mounts to the shaft. As the shaft rotates, the line-shaft spool rotates with it, which transmits the motion via a belt to the roller. The shaft axis is perpendicular to the axis of the rollers, which requires the belt to be twisted 90 degrees between the line-shaft spool and the roller. The way the belt is twisted determines which direction the roller rotates. Line shaft spools can also be used to drive curved conveyor sections, usually by using short shaft sections and universal joints. There are different types of line-shaft spools available including regular line-shaft spools, speed-up spools, keyed line-shaft spools, split spools, and shaft collars or C-clips. Regular line-shaft spools function as clutches on a line-shaft. When a conveyor becomes jammed, regular line-shaft spools will slip to prevent the belts from abrading. These types of spools also stop if hair or extremities get caught in the rollers. Regular line-shaft spools common come in two sizes: standard bore size for 1” and 25mm shafts, and large for size foor 1-7/16” and 36mm line-shafts. Speed-up line-shaft spools increase the conveyor’s roller speed by up to 44%. Keyed line-shaft spools are also commonly available. These spools will not slip, so it’s advisable to only use this type of line-shaft spool in sections where accumulation and jams are least likely. Keyed spools are typically designed for curves, inclines, or in areas where greater drive is required. Other types of line-shaft spools include split spools and shaft collars, also known as C-clips. Split spools are popular for line-shaft applications because they can be installed without disassembly of the shaft. This type of line-shaft spool can be locked to a shaft by using two-sided tape or electric filler tape. The split construction eliminates the need for keyed spools and shafts. Shaft collars, or C-clips, clamp onto a line shaft to keep spools in place. These are commonly 1/2” or 12.7mm wide.
