Abstract
A roller type pneumatic vibrator relates to a vibrator. At present, the inner diameter of a bearing of the pneumatic vibrator is connected with cylinders at two ends of an unbalanced rotor so that the radial diameter of a rolling bearing is limited, service life of the rolling bearing is shortened, and the bearing bears large dynamic load in the running process simultaneously. The roller type pneumatic vibrator comprises a vibrator seat with a cylindrical through hole, vibrator covers arranged at two ends of the vibrator seat and used for sealing a cavity formed by the through hole, an air inlet joint arranged at the top of the vibrator seat and communicated with the cavity, and a silencer. The roller type pneumatic vibrator is characterized in that an annular track matched with the cavity is arranged in the cavity, and a roller with the diameter smaller than that of an inner ring of the track is arranged in the track. When compressed air with a certain pressure is connected into the air inlet joint, the strong compressed air can blow the roller on the track to enable the roller to rotate on the track at high speed to produce vibration force, and vibration resistance and running stability are good.
Description
Technical field
The present invention relates to a kind of vibrator.
Background technology
According to vibrator institute power consumption form and operation principle, mainly contain electric vibrator (rotation, straight line, magnetic), the vibrator that surges, pneumatic vibrator (rotation, straight line) in the present vibrating machine industry.Electric vibrator is one group of eccentric block with motor drives two shaft extension ends, produces vibration force, and invariablenes turning speed is non-adjustable, and the vibration force adjustment is inconvenient, for high frequency, high temperature and explosion-proof required particular design.Surge exciter structure complicacy, heaviness, Installation and Debugging are extremely inconvenient.Pneumatic vibrator of the same type mainly contains seat, covers, is with formations such as unbalanced rotor, bearing; Rolling bearing is pressed in the bearing chamber; Bearing bore diameter is connected with being with unbalanced two ends of rotor cylinder; Limit the radial diameter of rolling bearing, reduced the physical life of rolling bearing, can receive great dynamic load at the running middle (center) bearing simultaneously.
Along with the vibrating machine industry to product safety, energy-conservationly require increasingly highly, above-mentioned vibrator has been difficult to satisfy shake frequency height, requirement light, adjustable, applied widely.
Summary of the invention
The technical problem that the present invention will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and a kind of roller shape pneumatic vibrator are provided, to reach the purpose that improves antivibration ability and operation stability.For this reason, the present invention takes following technical scheme.
A kind of roller shape pneumatic vibrator; Comprise the device seat of establishing cylindrical hole, be located at device seat two ends with the sealing through hole form cavity the device lid, be located at inlet suction port and silencer that device seat top is communicated with cavity; It is characterized in that: be provided with the circular orbit that matches with it in the cavity, insert the roller of diameter in the track less than the track inner ring diameter.After connecting the compressed air of certain pressure from inlet suction port, suppress the gas that contracts and can blow the roller on the track, make it in orbit rotation at a high speed, thereby produce vibration force, antivibration ability and good operation stability.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature.
Described device seat cavity middle part is provided with protruding spacing ring, and the internal diameter of spacing ring is greater than the internal diameter of track, and two circle tracks are symmetrically placed in the cavity of spacing ring both sides.The spacing ring indent is in track, and it does not rub with roller, simultaneously also as gas flow,
The roller middle part has the annular groove relative with spacing ring.The annular groove of roller and indent, are beneficial to roller and in cavity, roll as gas flow in the spacing ring of track; The annular groove of roller and indent all are positioned at the middle part in the spacing ring of track, avoid the vibrator axially loaded irregular.
The gas outlet of inlet suction port and the air inlet of silencer all with the annular groove of roller relatively and lay respectively at the radially both sides of cavity.
Inner track radius is 1.1～1.4 times of roller external diameter.Under identical device seat size condition, obtain big vibration force.Roller and orbit gap are too small, and air gap is little, and roller rolling power is little, and the vibration force of generation is little, and roller and orbit gap are excessive, and then vibrator structure is big, and roller is little, and under the condition of same volume, the vibration force of generation is little.
Vibrator is axial symmetrical structure.Make the vibrator axially loaded even, avoid local pressure.
The cylindrical hole two ends of device seat embed the device lid respectively, and the external diameter of device lid is greater than the external diameter of track; The inner face and the spacing ring of track offset, and its outer face and device lid offset.
Described roller is a hollow structure.
Beneficial effect: after connecting the compressed air of certain pressure, suppress the gas that contracts and to blow the roller on the track, make it in orbit rotation at a high speed, thereby produce vibration force, antivibration ability and good operation stability from inlet suction port.

The specific embodiment
Below in conjunction with Figure of description technical scheme of the present invention is done further detailed description.
The present invention includes the device seat 1 of establishing cylindrical hole, be located at device seat 1 two ends with the sealing through hole form cavity 7 device lid 2, be located at inlet suction port 3 and silencer 4 that device seat 1 top is communicated with cavity 7; Be provided with the circular orbit 5 that matches with it in the cavity 7, insert the roller 6 of diameter in the track 5 less than track 5 inner ring diameters.Described device seat 1 cavity 7 middle parts are provided with protruding spacing ring 8, and the internal diameter of spacing ring 8 is greater than the internal diameter of track 5, and two circle tracks 5 are symmetrically placed in the cavity 7 of spacing ring 8 both sides.Roller 6 middle parts have the annular groove 9 relative with spacing ring 8.The air inlet of the gas outlet of inlet suction port 3 and silencer 4 all with the annular groove of roller 69 relatively and lay respectively at the radially both sides of cavity 7.The cylindrical hole two ends of device seat 1 embed device lid 2 respectively, and the external diameter of device lid 2 is greater than the external diameter of track 5; The inner face of track 5 and spacing ring 8 offset, and its outer face and device lid 2 offset, and rock for avoiding track 5, and track 5 is an interference fit with cavity 7.Track 5 internal diameters are 1.1～1.4 times of roller 6 external diameters, and track 5 internal diameters are 1.2 times of roller 6 external diameters in the present embodiment, and roller 6 is a hollow structure.For avoiding the vibrator axially loaded irregular; Vibrator adopts axial symmetrical structure; Roller 6 axial symmetrical structures, two devices cover axially being symmetrical set of 2, two tracks 5, and the air inlet of the gas outlet of inlet suction port 3, silencer 4, spacing ring 8 all are positioned at vibrator shaft to the middle part.
