Abstract
The utility model discloses a duplex eccentric gear exciter, belonging to a vibrating device of vibrating machines, which is especially suitable for GZD series vibratory feed units. Aiming at the problems of the existing vibration exciter, the duplex eccentric gear exciter makes many great improvements: a separate box body is altered to an integral box body; stress by a cantilever supporting the middle part of a main shaft is altered to the stress by both ends supporting the middle part; lubricating-oil for lubrication is altered into lubricating grease for lubrication; four mounted parallel eccentric blocks are altered to two nested eccentric wheels. The improvements, with the featurs of simple structure, light weight, low cost, time saving, labour saving, high reliability and accuracy, relieves the trouble of disassembling the upper and lower box bodies of a motor in adjusting exciting force in work process.
Description
The utility model belongs to a kind of vibrating device of vibrating machine, is specially adapted to GZD series vibratory feed unit.
Present domestic cement industry is widely used, by the GZD series vibratory feed unit of Machinery Industry Ministry Fifth Design And Research Institute's design, the exciting force of its vibrator results from four eccentric blocks-two of the centres that are installed in parallel in the main shaft two ends that rotate at a high speed and is fixed eccentric block, and two of axle heads are the adjustable eccentric piece.The upper and lower adjustable eccentric piece of corresponding adjustment can change the size of exciting force with respect to the position of fixed eccentric block.But the user carries out this work in process of production, need take motor and upper and lower casing apart, wastes time and energy, and is very inconvenient, and do not note slightly, will make a mistake-upper and lower eccentric block is not corresponding, falls flat.
The purpose of the utility model design is: solves existing vibrator and adjusts the problem of exciting force trouble in process of production, thus both simply light when accomplishing to adjust, again accurately and reliably.
Feature of the present utility model is:
1. upper and lower casing and bearing dish three-major-items are integrated, be designed to monoblock type exciting case, not only alleviated vibrator weight, reduced the vibrator height, and improved the vibrator coaxial accuracy.Exciting force is adjusted in perforate on the cylinder of lower box garden simultaneously, can exempt the trouble of taking motor and upper and lower casing apart, not only saves time but also laborsaving.
2. it is stressed stressed for the two supports middle part to change main shaft middle part supporting extension arms, has improved main axis stiffness, has dwindled the main shaft diameter.
3. to change oil lubrication be grease lubrication to main shaft bearing, upper bearing (metal) adopts oil sealing sealing, lower bearing adopts end cap seal, simplified the lube system structure, and avoided too much causing eccentric block to stir oil because of the user refuels, add heavy load, and the phenomenon of dispensing motor.
4. the eccentric block that changes four parallel installations is the eccentric wheel of two suits, and promptly compound eccentric wheel is easy to process, and it is simple to adjust exciting force, and is difficult for making a mistake, accurately and reliably.
Introduce the method for structure of the present utility model, operation principle and adjustment exciting force in detail below in conjunction with accompanying drawing.
Accompanying drawing is a main cutaway view of the present utility model.Motor 27 places on the exciting case 1, and the shift fork 23 that is anchored on motor shaft head can drive crank 21 and main shaft 3 rotations that are anchored on main shaft 3 spindle noses by rolling bearing 22.Interior eccentric wheel 15 usefulness flat keys are fixed in main shaft 3 middle parts, and prevent its axial float with axle sleeve 5.In the outer eccentric wheel 14 that cuts a narrow radial slot in the entity thickness is set in matched in clearance on the eccentric wheel 15.Tighten the lock-screw 10 that is installed on the outer eccentric wheel 14 and vertically passes through radial slot, can make that radial slot narrows down, endoporus dwindles, and in outer eccentric wheel 14 is anchored on the eccentric wheel 15.Start motor, main axis rotation, then inside and outside eccentric wheel rotates synchronously.As long as inside and outside eccentric synthetic center of gravity does not overlap with the alignment of shafts, will produce exciting force.If the speed of mainshaft is certain, inside and outside eccentric wheel quality is certain, and then the size of exciting force depends on the distance of the inside and outside eccentric synthetic center of gravity and the alignment of shafts.This distance is big more, and exciting force is big more.Unclamp outer eccentric wheel lock-screw, change outer eccentric wheel, can adjust the distance of the inside and outside eccentric synthetic center of gravity and the alignment of shafts, thereby can adjust the size of exciting force with respect to interior eccentric position.
When adjusting exciting force in process of production, only need open garden arc cover plate 11, unclamp the lock-screw 10 of outer eccentric wheel 14, place the outer garden of interior eccentric wheel boss aperture with a spillikin, eccentric wheel 15 in stirring makes outer eccentric wheel 14 otch of outer garden exciting force groove (selected) aligning of its boss, tightens lock-screw 10 then, start motor, then this moment, exciting force was required exciting force.
If inside and outside eccentric wheel adopts same material, it is designed to uniform thickness, and two eccentric eccentric throws is designed to isometric, then its exciting force minimum can transfer to and level off to zero.
Compound eccentric wheel also can be loaded on spindle nose.The compound eccentric wheel that directly is loaded on motor shaft head is the simplest vibrator of adjustable exciting force.
