摘要： A vibrating screen apparatus capable of maintaining operation when in an out-of-level orientation is disclosed. The apparatus includes a generally rigid frame having first and second sidewalls and top and bottom screen decks extending therebetween. The frame is coupled to a stationary chassis or base by spring mount assemblies that each include an adjustable spring support system coupled to the frame and heavy coil springs which are positioned between the adjustable spring support system and the stationary base. Four rubber shear spring assemblies are also coupled between the stationary base and the sidewalls. The rubber shear spring assemblies help prevent shifting of the frame relative to the base if an out-of-level condition occurs and also help reduce lateral forces applied to the coil springs caused during out-of-level conditions. The apparatus further includes eccentric drive and driven shafts that are rotatably supported by spherical roller bearings. First and second oil housings are located adjacent the respective first and second sidewalls and define oil chambers to lubricate the shaft bearings. Labyrinth seals are located on the shafts adjacent each bearing and are designed to prevent lubricating oil from passing beyond them. O-rings are coupled to each of the shafts adjacent the labyrinth seals and are designed to direct lubricating oil which passes beyond the labyrinth seals into supplemental oil collection pockets that direct the lubricating oil to the oil chambers of the oil housings for re-use in lubricating the bearings.

摘要： A vibrating screen apparatus includes a frame and a screen having a first end coupled to an anchor beam which is rigidly coupled to the frame. The apparatus also includes a tension control assembly coupled to a second end of the screen for tensioning the screen to substantially a predetermined tension. The tension control assembly is rotatably coupled to the frame spaced apart from the anchor beam. The tension control assembly changes the tension of the screen upon rotation of the tension control assembly relative to the frame about an axis of rotation. The apparatus further includes an adjusting mechanism for moving the tension plate in a direction normal to the axis of rotation of the tension plate to compensate for nonuniform tension of the screen.
