Abstract: A bearing support for facilitating removal and replacement of a bearing and supporting the rotatable shaft while the bearing is removed from the shaft. The bearing support includes a bearing support including a bearing mounting structure for being supported on the machine. A bearing assembly is provided for receiving a portion of the shaft. A bearing housing assembly is positioned between the bearing assembly and the bearing mounting structure. The bearing assembly is supported on the bearing housing assembly and the bearing housing assembly is supported on the bearing mounting structure. The bearing housing assembly is removable from the bearing mounting structure prior to removal of the bearing assembly from the shaft for facilitating removal of the bearing assembly from the shaft. Another aspect of the invention includes a shaft support system for facilitating removal and replacement of a bearing assembly adapted for supporting a shaft on a machine.

Abstract: A new dual motor drive system for a roller grinder. The inventive device includes a roller grinder having top and bottom sets of rollers extending between the sides of the roller grinder. Each set of rollers has a front roller and a back roller. Each roller of each set of rollers has a shaft having a pair of opposite ends. A first pulley is coupled to the end of the front roller of the top set of rollers extending from the first side of the roller grinder. A second pulley is coupled to the end of the front roller of the bottom set of rollers extending from the first side of the roller grinder. A third pulley is coupled to the end of the back roller of the top set of rollers extending from the second side of the roller grinder. A fourth pulley is coupled to the end of the back roller of the bottom set of rollers extending from the second side of the roller grinder. First and second motors are provided each having a rotating shaft extending therefrom.

Abstract: A new roller alignment system for permitting quick and precise alignment of the rollers. The inventive device includes first and second side subassemblies, and an elongate linking rod. Each side subassembly comprises an adjustment bracket and threaded elongate upper and lower adjustment rods. The adjustment bracket is pivotally coupled a side of a roller grinder housing which abuts an end of a back roller of the roller grinder. The back end of the upper first adjustment rod is extended through the upper end of the first adjustment bracket while the front end of the upper first adjustment rod is positioned adjacent the front of the housing. The front end of the lower first adjustment rod is outwardly extended from the front of the housing. A adjustment nut is threaded on the front end of the lower adjustment rod and a coarse adjustment member is coupled to the front end of the upper adjustment rod. The coarse adjustment member is pivotally mounted on a side of the housing.
