Abstract: A troughing side idler for use with a belt conveyor having upstanding first and second side walls. A first troughing side idler is secured to the first side wall and a second troughing side idler is secured to the second side wall. A horizontally extending medial roller extends between the first and second side walls for cooperation with the side idlers to shape the conveyor belt into a trough. Each of the side idlers includes an idler roller having a shaft which extends upwardly and outwardly through inner and outer bearings which are secured to a bearing bracket housing which is operatively secured to the associated side wall. The upper outer end of the shaft has an annular groove formed therein. A set screw extends through the inner ring of the outer bearing and extends into the annular groove in the shaft. A set screw extends through the inner ring of the inner bearing for frictional engagement with the shaft. A fender washer is secured to the outer end of the shaft.

A roller conveyor (1) is also provided, which includes an endless belt (2) for transporting a bulk material (3) and a plurality of idler rollers for supporting the endless belt (2), wherein one or more of the idler rollers (4, 5, 6) are in accordance with the invention.

Abstract: The present invention relates to an idler frame assembly for a conveyor, the idler frame assembly including a fixed frame assembly mounted on the main frame, a roller support assembly slidably engaged with the fixed frame assembly, the roller support assembly being slidable relative to the fixed frame assembly between an operative configuration and a non-operative configuration, the roller support assembly including a pivotable roller support frame, the pivotable roller support frame being pivotable between a raised operative position and a lowered inoperative position, and a guide means mounted on the fixed frame assembly for urging the pivotable roller support frame to move from the lowered inoperative position to the raised operative position when the roller support assembly is slidably engaged with the fixed frame in the operative configuration.

Abstract: A roller device mountable rotatably on a spindle includes a roller body having a tubular wall with two opposite open-end portions. Each open-end portion is provided with a retaining member formed on an inner peripheral surface of the tubular wall. Two covers are inserted respectively into the open-end portions of the tubular wall, and are adapted to be sleeved rotatably around the spindle. Each cover has an annular end wall transverse to the corresponding open-end portion, a surrounding wall extending inwardly and axially from an outer periphery of the end wall and abutting against the inner peripheral surface of the tubular wall, and an engaging member formed on an outer peripheral surface of the surrounding wall and interlocking the retaining member. The retaining and engaging members have recess-and-protrusion interlocking surfaces.

Abstract: A troughing idler of an enclosed belt conveyor has a horizontal shaft that is supported by antifriction bearings mounted outside of the side walls of the trunking and carries a medial roller. Each of the side walls of the trunking supports a downwardly and inwardly sloping side roller in cantilevered relation by means of a side roller carrier that is mounted on the side wall and includes a spindle, a hub, and inboard and outboard antifriction bearings interposed between the spindle and the hub. The medial roller and the side rollers are arranged relative to each other so as to support the belt with side portions sloping upwardly and outwardly with respect to a medial portion.

Abstract: Stub idler units for a flexible sidewall belt conveyors support the return belt run. Each unit includes a stub roll fixed to and forming an integral part of a solid shaft. A pair of re-lubricable, sealed bearings are mounted within opposite ends of a tubular bearing housing secured within a tubular mounting bracket. The shaft is journaled in the bearings clamped to the housing by a locking nut on the shaft end. A lubrication passageway is formed in the mounting bracket and housing and provided with a lubrication fitting. The passageway connects to the chamber between the bearings lubricating the bearings. A flexible hydraulic grease line is attached to the far side mounting bracket in place of the grease fitting. The grease line extends across the conveyor belt to the near side of the conveyor and terminates in a grease fitting for re-lubrication of the far side stub idler. The line is supported at the two mounting brackets by suitable shaped support elements mounted to the mounting brackets.

Abstract: A conveyor belt advances over an assembly of cylindrical idler rollers. Each idler roller includes a cylindrical body rotatable about an axially disposed tubular shaft. Air under pressure enters the proximal end of the tubular shaft and advances through the tubular shaft to be discharged through openings in the distal end of the tubular shaft. The air under pressure leaving the distal end of the tubular shaft advances through the space between the inner wall of the cylindrical body of the idler roller and the outer wall of the tubular shaft to be vented to atmosphere for reducing heat build-up in the idler roller.

Abstract: Stub idler roll units for flexible sidewall belt conveyors are mounted to support the return run of a sidewall belt. The stub idler roll unit includes a stub roll fixed to and forming an integral part of a support shaft. The shaft extends from the roll and is journaled in a pair of re-lubricable, sealed bearings, secured with a tubular bracket having a mounting plate for mounting of a roll unit to the conveyor. A tubular bearing housing is secured within the bracket and has end recesses to receive a bearing and end washer. The outer end of the shaft is threaded and the shaft and roll is clamped to the housing by jam nuts on the outer end of the shaft, the washer abuts the housing to take the clamping load and insure adequate operating clearances. The shaft has an axial passageway extending from the outer end of the shaft and provided with a lubricating fitting.

Abstract: A belt conveyor includes an assembly of conveyor idler rollers for supporting a conveyor belt advancing thereon. Each conveyor idler roller includes a cylindrical body that is freely rotatable about a shaft. A keeper seal prevents axial displacement of the cylindrical body along the shaft and inhibits foreign matter from penetrating into the central opening of the cylindrical body. The keeper seal comprises a radially projecting collar at the proximal end of the shaft which mates with a radially projecting groove formed in the cylindrical body to prevent axial displacement of the cylindrical body along the shaft and to inhibit foreign matter from penetrating the central opening of the cylindrical body.

Abstract: The present invention discloses an inclining consecutive alternating direction track storage conveyor system including at least one or more axles having at least two or more discs positioned on the axle for changing direction of a belt from one inclining track to the next inclining consecutive alternating direction track. Also, a staggered roller body configuration track is disclosed.

Abstract: An idler trough roller assembly adapted to be mounted along a supporting frame to support the upper flight of a belt conveyor during movement of bulk material. Fixed angular supports are mounted on the frame. Each support has an outside cylindrical surface. The cylindrical surfaces of the individual supports are discontinued along a plane that forms an acute angle relative to the support axis. Individual rollers are fitted about each support. The rollers are each cup-shaped, with coaxial cylindrical inside and outside surfaces and an integral cap enclosing and completely covering the roller outer end. A radially projecting shoulder at the outer end of each support and an interfitting groove within each roller prevent axial movement of the assembled roller with respect to the support.

Abstract: A belt conveyor of the extendible type wherein stools are provided which complete with respective upper and lower belt supporting elements can readily and reliably be introduced into the extendible portion of the conveyor during operation of the conveyor. Each such stool is provided with a gap at one side thereof and between its upper and lower elements to enable it to be inserted into the run of the conveyor in a direction transversely thereof. When so inserted the stool is disposed with its upper element above the lower run of the belt and with its lower element below the lower run of the belt.
