Invention content
The purpose of the utility model is to overcome above-mentioned existing common action of forced stirring mixing time is short, stirring intensity is low, mixes and stirs
It is of poor quality and existing take effect of vibration existing for Vibration Cylinder Body or Vibratory Mixing method by the way of eccentric block exciting
The shortcomings that effect unobvious, equipment dependability is poor, provide it is a kind of it is simple in structure, manufacture is at low cost, function and effect are good, reliability is high
Eccentric shaft type oscillating mixer.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of eccentric shaft type oscillating mixer mixes cylinder in rack including being arranged on, mixes and agitating device is provided in cylinder, stir
The one end of the mixing shaft for mixing device is supported on by bearing I in rack, and the other end is supported on the bias of exciting device by bearing II
In the gearratio of cycloid axle formation of axis, which is processing and manufacturing eccentric structure, and agitating device is connected with mixer drive, exciting device
It is connected with oscillation drive.
Further, the exciting device includes eccentric shaft, bearing block I, bearing III, bearing II and bearing block II, belt
Wheel, eccentric shaft include gearratio of cycloid axle formation and non-eccentricity shaft part, and non-eccentricity shaft part is supported on by bearing III in bearing block I, outer end
It is connected by belt pulley with oscillation drive, gearratio of cycloid axle formation is inserted by bearing II in bearing block II, and bearing block II is with stirring
Axis one end is mixed to be connected, wherein, non-eccentricity shaft part axis is the centre of gyration line of eccentric shaft, gearratio of cycloid axle formation axis and the centre of gyration
There is offset in line, keyway is opened up on axis body or setting other structures may result in the shaft part mass eccentricity, as long as but
Non-eccentricity shaft part axis and centre of gyration line are coaxial, non-mass bias.
Further, the axis deviant of the gearratio of cycloid axle formation and non-eccentricity shaft part be 0.4 ~ 0.9mm, preferred value 0.6mm,
According to experimental study, when axis deviant is less than 0.4mm, effect of vibration effect is poor, when axis deviant is more than 0.9mm,
Whole aircraft reliability is poor.
Further, the angle of inclination of the inside and outside circle of the bearing I and bearing II is not less than the angle of inclination of agitating shaft,
Setting is that there are gearratio of cycloid axle formation because of eccentric shaft in this way, and after installation, for agitating shaft i.e. there are angle of inclination, agitating shaft passes through bearing branch
Support, therefore it is required that the angle of inclination of the Internal and external cycle of spring bearing can compensate for the angle of inclination of agitating shaft, otherwise bearing suppress it is dead or
Failure.
Further, the working speed of the eccentric shaft is not less than 1000rpm, and preferred value 1800rpm is ground according to experiment
Study carefully, when the working speed of eccentric shaft is less than 1000rpm, effect of vibration effect is poor.
Further, the agitating device includes at least two agitating shafts, and each agitating shaft is real by the roller gear of end
Existing engaged transmission, and the backlash between roller gear is not less than stirring axis angular displacement;Due to eccentric shaft, there are gearratio of cycloid axle formation, peaces
After dress, for agitating shaft i.e. there are angle of inclination, agitating shaft generates certain angle position by roller gear engaged transmission, gear engagement place
It moves, therefore it is required that the backlash between roller gear can compensate for the angular displacement that the inclination of agitating shaft generates, otherwise roller gear
Suppress dead or failure.
Further, the agitating device includes at least two agitating shafts, and each agitating shaft is real by the drum gear of end
Existing engaged transmission, and the offset angle between drum gear is not less than the angle of inclination of agitating shaft.
Further, I outside of the bearing block is provided with radiator, radiator mainly to bearing III, bearing II and
Bearing block I, bearing block II radiate, and radiator is cooling fin or radiator fan.
Further, the bearing block I, II end set of bearing block have bearing gland.
The utility model this have the advantage that:
1. eccentric shaft type oscillating mixer provided by the utility model, amplitude and frequency be not by load effect, agitating device
Action of forced stirring is carried out to mixture and obtains the mixture of even macroscopic, while applies the effect of high frequency tentering periodic vibration, is improved
The microscopic uniformity of mixture, and make material more uniform, closely knit, it is easy to construct, has a vast market prospect;
2. since eccentric shaft is processing and manufacturing eccentric structure, eccentric shaft includes gearratio of cycloid axle formation and non-eccentricity shaft part, non-eccentricity
Shaft part is supported on by bearing III in bearing block I, and outer end is connected by belt pulley with oscillation drive, and gearratio of cycloid axle formation passes through
Bearing II is inserted into bearing block II, and bearing block II is connected with one end of the mixing shaft, wherein, non-eccentricity shaft part axis is eccentric shaft
Axis of rotation, gearratio of cycloid axle formation axis and axis of rotation, which exist, to be deviated, and non-eccentricity shaft part spindle line and axis of rotation are coaxial, and
Non-mass is eccentric, and such eccentric setting is more ingenious, and the eccentric vibrating effect than conventional eccentric block type is more preferable, and transmission more may be used
It leans on;
3. since the angle of inclination of bearing I and the inside and outside circle of bearing II is not less than the angle of inclination of agitating shaft, set in this way
It is because eccentric shaft is there are gearratio of cycloid axle formation, after installation, agitating shaft is i.e. there are angle of inclination, and agitating shaft is by bearings, therefore
The angle of inclination of the Internal and external cycle of spring bearing can compensate for the angle of inclination of agitating shaft, and bearing is avoided to suppress dead or failure generation;
4. the agitating shaft due to agitating device realizes engaged transmission, and the tooth between roller gear by the roller gear of end
Side clearance is not less than stirring axis angular displacement, and setting in this way is that there are gearratio of cycloid axle formation due to eccentric shaft, and after installation, agitating shaft exists
Angle of inclination, agitating shaft is by roller gear engaged transmission, and gear engagement place generates certain angular displacement, if therefore roller gear
Between backlash can compensate for the angular displacement that the inclination of agitating shaft generates, you can roller gear is avoided to suppress dead or failure;
5. since the outside of bearing block I is provided with radiator, radiator mainly to bearing III, bearing II and bearing block I,
Bearing block II radiates, and work caused by avoiding the occurrence of bearing running hot is unreliable;
6. having bearing gland in bearing block I, II end set of bearing block, avoiding bearing, protection bearing persistently works into ash.
