Special bearing for vibrating screen

Abstract

The invention discloses a special bearing for a vibrating screen. The bearing comprises a cast iron base, a shock absorption layer, air bags, a micro spring and silencing plates; the shock absorptionlayer is fixed at the center position in the cast iron base; the silencing plates are mounted in the parts, on the two sides of the shock absorption layer, of the cast iron base and are filled with the air bags; fixing rings are mounted on the two sides of the surface of the cast iron base; arc pads are fixed at the edge positions of the fixing rings; a dustproof bearing housing is welded at the center position of the top end of the cast iron base, oil storage plates are mounted at the two ends in an upper oil ring; a non-return rigid inner ring is fixed in the dustproof bearing housing; and atraveling ring is arranged on one side, far away from the non-return rigid inner ring, of an elastic supporting retainer. The bearing facilitates disassembly and maintenance by workers and can reducenoise generated in bearing vibration, and the abrasion in the use process of the bearing is reduced.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to special bearings for vibrating screens. Background technique [0002] The vibrating screen works by using the reciprocating rotary vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The effect is to make the screen surface produce double-rotating vibration, and its vibration track is a complex space curve. The curve is projected as a circle on the horizontal plane, while the projection on the vertical plane is an ellipse. Adjust the vertical rotation weight The exciting force can change the amplitude, and adjusting the space phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material o...
