Abstract
The invention discloses a vibrating-dewatering screen driving mechanism. Two same bearing pedestals are symmetrically and fixedly arranged at an edge opening at the upper part of a screen frame; an eccentric sleeve is fixedly arranged in an inner hole of each bearing pedestal through two bearings; an isolating sleeve is arranged between the two bearings on the outer circle of each eccentric sleeve; a transmission shaft is fixedly arranged in inner holes of the two eccentric sleeves through keys; a bearing pedestal gland is fixedly arranged at the port at each of two ends of each bearing pedestal; a tower-shaped rubber sleeve is fixed at the outer edge opening of each bearing gland through a ring-shaped press plate and a bolt; and a spring pull ring is sleeved on the outer circle of the small head of each tower-shaped rubber sleeve. By the vibrating-dewatering screen driving mechanism, the service life of the bearings and the overall service life of equipment can be prolonged; and furthermore, the vibrating-dewatering screen driving mechanism has the advantages of simple structure, relatively high manufacturing technique, relatively low manufacturing cost and long service life.
Description
Technical field
The present invention relates to cleaning unit, be specifically related to vibrating-dewatering screen, relate in particular to the driving mechanism of vibrating-dewatering screen vibration, belong to the vibrating-dewatering screen technical field.
Background technology
At present, the driving mechanism of vibrating-dewatering screen generally comprises symmetry and is fixed on the pair of bearing of sieving on the basket, the eccentric position of bent axle is installed on the bearing block by sliding bearing, in the driving mechanism of this type, the sealing property of bearing is relatively poor, and the vibratory sieve environment of working is generally more abominable in addition, and bearing wear is serious, cause the service life of equipment lower, in addition, in existing vibratory sieve driving mechanism, the eccentric shaft of transferring power generally is whole structure, exist manufacturing process complicated, the defective that manufacturing cost is higher, simultaneously, because the eccentric part force-bearing situation of driving shaft is complicated, it is also more serious to wear and tear, in case the wearing and tearing of eccentric position surpass certain limit, whole driving shaft also just has to scrap, so, reduce further the service life of equipment, and increased the use cost of equipment.
Summary of the invention
The object of the invention is to: for the existing defects of existing vibrating-dewatering screen driving mechanism, the invention provides a kind of vibrating-dewatering screen driving mechanism of new structure, overcome the existing existing defects of vibrating-dewatering screen driving mechanism.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of vibrating-dewatering screen driving mechanism, comprise screen frame, bearing block, bearing gland, annular pressing plate, the pagoda-shaped rubber bush, spring draws circle, key, bearing, spacer, eccentric bushing, power transmission shaft, two identical bearing blocks are fixed on screen frame upper edge mouth position symmetrically, in the endoporus of each bearing block, install and fix an eccentric bushing by two bearings, between two bearings of the cylindrical of each eccentric bushing, spacer is installed, in the endoporus of two eccentric bushings, install and fix a power transmission shaft by key, the eccentric direction of two eccentric bushings is consistent, install and fix a bearing block gland in the both sides of each bearing block port position, the seam position of described bearing gland and the outer ring of bearing compress, fix a pagoda-shaped rubber bush at the outside of each bearing gland port part with annular pressing plate and screw, draw circle at spring of microcephaly's cylindrical of pagoda-shaped rubber bush socket.
Beneficial effect: the present invention is because after adopting said method, the sealing property of bearing is improved greatly, effectively reduce the generation of bearing heel and toe wear situation, thereby improve the life-span of bearing and the bulk life time of equipment, simultaneously, because power transmission shaft and the eccentric bushing that forms rotor journal are version independently, so, have simple in structure, anufacturability better, manufacturing cost is lower, service life is higher advantage.
