The pneumatic vibrator mainly consists of a cylindrical cavity appliance seat (1) with openings at both ends thereof, appliance covers (2) which are arranged at both ends of the appliance seat (1) and used for closing the openings, bearing covers (7) of two built-in bearings (4) arranged in the appliance seat (1), an unbalanced turbine (6) which is arranged between the two bearing covers (7) and provided with a metal cylinder (3), a hollow hole (9) and a skewed tooth (11), a gas inlet joint (10) which is arranged outside the appliance seat (1) and communicates with the cylindrical cavity of the appliance seat (1), a silencer (9) which is arranged outside the appliance seat (1) and communicates with the cylindrical cavity of the appliance seat (1), and the like. The turbo-type pneumatic vibrator has more reasonable and compact overall structure, effectively improves the anti-vibration capacity and the operation stability of the pneumatic vibrator, prolongs the service life, and has the remarkable advantages of low noise, high vibration frequency, large vibration force, convenient assembly and disassembly and the like.
Description
Technical field
The utility model relates to a kind of Scroll-type pneumatic vibrator with unbalanced rotor, belongs to vibration source technical field in the vibrating machine industry.
Background technology
According to vibrator institute power consumption form and operation principle, mainly contain electric vibrator (rotation, straight line, magnetic), the vibrator that surges (rotation), 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 vibration force is adjusted inconvenient, needs particular design for high frequency, high temperature and explosion-proof place.Surge exciter structure complexity, heaviness, Installation and Debugging are extremely inconvenient.Pneumatic vibrator of the same type mainly is made of the rotor of seat, lid, band out-of-balance mass, bearing etc., rolling bearing is pressed in the bearing chamber, bearing bore diameter is connected with the two ends of rotor cylinder axis of band out-of-balance mass, limited the radial diameter of rolling bearing, reduce the service life of rolling bearing, can be subjected to great dynamic load at the running middle (center) bearing simultaneously.
Along with the vibrating machine industry is more and more higher to product safety, energy-conservation requirement, above-mentioned vibrator has been difficult to satisfy shake frequency height, requirement light, adjustable, applied widely.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively improve the Scroll-type pneumatic vibrator of the band unbalanced rotor of antivibration ability and operation stability.
The utility model is the Scroll-type pneumatic vibrator of band unbalanced rotor, the cylindrical cavity device seat that comprises both ends open, place device seat two ends to be used for the device lid of closed above-mentioned opening, the inlet suction port that places device seat top to be connected with the cylindrical cavity of device seat, it is characterized in that being provided with in the cylindrical cavity two ends of device seat the bearing cap of two built-in bearings, be provided with the uneven turbine of being with metal cylinder and hollow hole between two bearing caps, the central rotating shaft of uneven turbine places in the bearing.During use, the compressed air of the certain pressure that is fed by inlet suction port enters in the cylindrical cavity of device seat, blows uneven turbine, makes it rotation at a high speed, produces vibration force.
Described metal cylinder can be 1～3 arranged distribution on uneven turbine circumference, hollow hole is 2～5 arranged distribution on uneven turbine circumference.
Described metal cylinder is placed in the hollow hole on the uneven turbine.
Also can be provided with helical teeth on the periphery of described uneven turbine.
Described device seat also can be provided with the muffler that is connected with the cylindrical cavity of device seat outward.
The utility model passes through optimal design and the rational deployment to the bearing cap of the uneven turbine of band metal cylinder and hollow hole in the device seat, built-in bearing, make the overall structure of pneumatic vibrator more become rationally compact, many deficiencies that prior art exists have been overcome, effectively improved the stability of pneumatic vibrator antivibration ability and operation, in the service life that has prolonged, have that noise is low, shake frequency is high, vibration force is big, be convenient to outstanding advantage and good effects such as installation and removal.The utility model can be widely used in the transportation work of material on workbench such as hopper, conveyer belt etc.
Description of drawings
Fig. 1 is a Facad structure schematic diagram of the present utility model;
Fig. 2 is a side structure cutaway view of the present utility model.
Among the figure: 1 is the device seat, and 2 are the device lid, and 3 is metal cylinder, and 4 is bearing, and 5 is the turbine central rotating shaft, and 6 is uneven turbine, and 7 is bearing cap, and 8 is the turbine hollow hole, and 9 is muffler, and 10 is inlet suction port, and 11 is the turbine helical teeth.
The specific embodiment
The utility model is mainly by the cylindrical cavity device seat 1 of both ends open, place device seat 1 two ends to be used for the device lid 2 of closed above-mentioned opening, place the bearing cap 7 of two built-in bearings 4 in the device seat 1, place the uneven turbine 6 of band metal cylinder 3, hollow hole 9 and helical teeth 11 between two bearing caps 7, place the device seat 1 outer inlet suction port 10 that is connected with the cylindrical cavity of device seat 1, place device seat 1 outer muffler 9 formations such as grade that are connected with the cylindrical cavity of device seat 1, the central rotating shaft 5 of uneven turbine 6 places in bearing 4 endoporus.Device seat 1 is used for fixing the external structure of vibrator and the vibration and the impact of opposing vibrator.
Uneven turbine 6 is cylinder type rotors that have a plurality of inhomogeneous circumferential holes, and wherein 1～3 hole is filled with heavy duty metal cylinder 3, and other 2～5 be hollow hole 9, obtains required uneven effect by processing method so.
During use, the compressed air of certain pressure is by inlet suction port 10, air admission hole through the band constant slope blows on the helical teeth 11 of uneven turbine 6 cylindricals, flow fast in the gap of compressed air between uneven turbine 6 and device seat 1 inner chamber, drive uneven turbine 6 and produce rotation at a high speed, produce vibration.Uneven turbine 6 does not contact with device seat 1 inwall in the high speed rotary course, can not produce the noise that human body is difficult to bear.
