Abstract
A conveyor belt comprising a plurality of link assemblies connected together by a plurality of link shafts. The conveyor belt includes a plurality of first guards with each first guard connected to one end of one link assemblies and encompassing one end of one of the link shafts for protecting the end of the link shaft and substantially preventing the end of the link shaft from engaging objects during the operation of the conveyor belt. A plurality of second guards are connected to the opposite end of the link assemblies for encompassing the opposite ends of the link shaft for protecting such opposite ends and substantially preventing such opposite ends from engaging objects during the operation of the conveyor belt. The link shafts extend through openings provided in the link assemblies and each opening is formed on a radius larger than the radius of the links shaft for providing shaft rocking surfaces so that the link shafts roll on the shaft rocking surfaces for substantially reducing rotating friction between the link shafts and adjacent portions of the link assemblies. Each link assembly comprises at least two modules which are positioned in an end-to-end relationship in the assembled position of the link assemblies. The modules in one set of link assemblies are formed of a plurality of whole links, and the modules in one other set of link assemblies are formed of a plurality of whole links with last link in each module to be placed near the last link in each module to be placed near the last link in an adjacent module in the assembled position of the link assembly comprising a half link. The sets of link assemblies are alternatively disposed in the conveyor belt so that every alternate row of connected links comprises only whole links with no spacing or joints between modules.
