Description
Technical field
The utility model relates to a kind of vibrator, and particularly a kind of vibratory sieve vibrator that relates to muddy water processing, mud conditioning and material screening and conveying belongs to the plant equipment field.
Background technology
The hydraulic vibration exciter that uses in the present industrial production is generally formed the vibrations oil cylinder by vibrations oil cylinder, pilot operated directional control valve, flexible member and hydraulic system and is two rod differential cylinders, and its end is as shaking original paper, and the other end and flexible member connect.This Hydraulic Elements adopt hydraulic system to guarantee the vibrational system frequency stabilization and make it easy to adjustly (consult impurity " heavy-duty machinery " first phase in 1994, the 51st page and magazine " Chinese mechanical engineering " the 8th phase in 1999, the 866th page.)。2006.03.15 Patent Office of the People's Republic of China discloses the utility model patent (patent No.: 200520029824.8), comprise casing, be arranged on the stator and rotor in the described casing of a kind of " motor vibration exciter " by name; The two-port of described casing is connected mutually with bearing block respectively; Described armature spindle two ends are run through respectively in the dead eye on the described bearing block; Symmetry is fixed with eccentric massblock respectively on the armature spindle that is positioned at described bearing both sides; Two-port at described casing is respectively arranged with the guard shield that is connected mutually with described bearing block.The advantage of this utility model is to compare with domestic used vibrating motor, has prolonged bearing service life, and foundation bolt is easy fracture not also.2007.02.14, Patent Office of the People's Republic of China discloses the utility model patent (patent No.: 200610017135.4) of a kind of " internal bearing type vibromill vibration exciter " by name, relate to a kind of internal bearing type vibromill vibration exciter, its technical scheme that adopts is: the axle of motor stretches into housing by the hole of housing lower end, and connects with the lower end of bearing cap axle is flexible; The upper end of bearing cap axle and the lower end of secter pat are fixedly connected; The upper flange plate inward flange of vibrator support and housing upper end outward flange rigid attachment; Reel is divided into two parts, and top is divided into cover plate, and the bottom is divided into interior axle; Cover plate covers on housing and the housing fluid-tight engagement, and is fixedly connected with the upper flange plate of vibrator support; Interior shaft extension go in the circular hole of secter pat with secter pat movingly.This utility model is compared with vibrator before, adopt reel to replace prior art middle shell top, adopt movingly between the interior axle of reel lower part and the secter pat, motor shaft makes secter pat around interior axle rotation by the bearing cap axle, it is simple that motor shaft bears stress, only bear twisting resistance, frangibility not, long service life.
Development along with the motor synchronizing technology, all types of self-synchronizing vibrating screens, basically all adopt the mode of the direct exciting of shock electric machine to turn round, this has just proposed more and more harsher requirement to the quality of shock electric machine and technical conditions etc., particularly to big exciting force vibrator.Simultaneously, when big exciting force was required, the quality requirement to excitation system self was light more good more again.This contradiction is very sharp-pointed.Especially in oil drilling vibratory sieve for example, " bottleneck " problem that has become the type vibratory sieve to further develop.And existing shock electric machine, comprise above-mentioned two patents, because its exciting force size is achieved by a variety of factors with " power matter ratio " (being the ratio of the size and the sole mass size of exciting force) of sole mass size, be difficult to be further improved, particularly be difficult to be greatly enhanced.On the other hand, if adopt existing short shock electric machine, because the quality of himself is added the quality of short motor bearing parts, just make its gross mass increase greatly, and motor adds the useful space that support unit has also taken the compass screen surface top, and this is difficult to accept for multi-deck screen especially.Therefore, press for technically and can have breakthrough, to solve the particular problem that improves excitation system self " power matter ratio " and " large span ".
Summary of the invention
The utility model provides a kind of vibrator for solving the aforementioned problems in the prior, and the utility model has effectively been realized raising excitation system self " power matter ratio " and " large span ".The utility model is simple in structure, manufacturing is easy for installation, long service life, reliability height, with low cost, special-purpose microscler large span shock electric machine cost performance than present employing is greatly improved, and has broken through the microscler large span shock electric machine of existing usefulness span and be difficult to the limitation that further increases again.
The technical solution of the utility model is to be achieved by following content:
A kind of large span vibrator, involving vibrations sieve and motor, it is characterized in that: described motor adopts the antivibration motor, antivibration motor two ends link to each other with universal drive shaft by shaft coupling, universal drive shaft is connected with at least two eccentric massblocks by shaft coupling again, eccentric massblock by bearing and bearing block support on the motor base of sieve box side plate; Whole vibrator connects into as a whole by the lengthening cylinder part that links to each other with antivibration motor housing two ends.
Described antivibration motor is flame proof antivibration or non-flame proof antivibration motor.
Because what adopted in this vibrator is the antivibration motor, it directly is not connected with eccentric massblock, thereby, whole motor directly is not subjected to by the eccentric block rotation radially effect of centrifugal exciting force that produces, therefore, the load of its bearing and motor housing etc. can alleviate greatly, thereby the quality of whole motor also just can reduce greatly.
Because this vibrator is in the vibratory sieve operation process, mainly be to provide radially exciting force acting by the rotating eccentricity mass, torque is very little after electric motor starting enters steady running, so motor is to the demand of the providing energy, just bigger when starting, and power demand is just very little after entering steady running, so this vibrator also can adopt variable frequency starting to reach the purpose of energy savings.Because novel vibrator sole mass alleviates and exciting force can improve greatly greatly, therefore, the diameter of axle that adopts this novel vibrator just can improve the relevant dynamic characteristic parameter of vibratory sieve such as amplitude, throwing index, vibration shape track major and minor axis greatly compares or the like.
This novel exciter structure is simple, it is easy for installation to make, long service life, reliability height, with low cost, be widely used, than the special-purpose microscler large span shock electric machine of present employing, its cost performance can obtain the raising of very big amplitude.And, break through the microscler large span shock electric machine of existing special use span and be difficult to again the further limitation of increase.
