The utility model relates to a kind of direct-connected air compressor.
Direct-connected air compressor is to rely on reciprocating motion of the pistons to gas holder pressurized air, generally comprise piston, connecting rod, cylinder, eccentric balancing blocks, rotor, motor cabinet, fan blade, gas holder, its working procedure is to be rotated by rotor, driving eccentric balancing blocks rotates around motor shaft, the drivening rod motion, piston is moved reciprocatingly in cylinder block, pressurized air enters gas holder, fan blade is installed in the other end of machine shaft, play ventilation and heat to reduce motor and cylinder temperature, these parts are normally made the equalizing feature of a symmetry, reduce unbalanced factor as far as possible.The piston type reciprocating machine will inevitably produce vibration, at present small-sized direct-connected air compressor manufacturer, all adopt and make eccentric balancing blocks reach the drawing requirement man-hour adding as far as possible, in the hope of when working, reaching transient equiliblium, reduce vibration with this, but because mechanical processing technique, the material uniformity coefficient, alignment error, all multifactor impacts such as structural design, be difficult to reach the design load of expection, therefore the vibration that complete machine is produced when work of most direct-connected air compressors is all very big, with the naked eye just can see tangible cylinder vibration, if when work, complete machine did not add fixingly, complete machine will produce mobile voluntarily.Vibration has strengthened the noise of complete machine, and it is loosening that each fastening piece is easy to generate, and the reliability of reduce using, and directly influence service life of a machine at present, lacks and a kind ofly can effectively reduce vibrative thus scheme.
The purpose of this utility model provides a kind of direct-connected air compressor that can reduce vibration effectively.
The utility model is achieved in that a kind of direct-connected air compressor, comprise piston, connecting rod, cylinder, eccentric balancing blocks, rotor, motor cabinet, fan blade, gas holder, rotor rotates, the drive fan blade rotates, and drive eccentric balancing blocks and rotate around motor shaft, the drivening rod motion moves reciprocatingly piston in cylinder block, pressurized air enters gas holder, is characterized in: the balancing weight that rotates around motor rotation axis is housed on the motor rotation axis of fan blade one end of described motor.
Embodiment has: above-mentioned balancing weight is a side margin place of fan blade fixedly.
Also can be: an axle sleeve is installed on the fan blade one side motor shaft of above-mentioned motor, axle sleeve has the hole of an internal thread corresponding with the connecting rod screw thread, connecting rod is the connecting rod that an end has the Full Thread FT of nut, one end of this connecting rod links to each other with the hole of axle sleeve, the nut of this end is fastened on connecting rod on the axle sleeve on the connecting rod, and axle sleeve is fixed on the motor shaft, above-mentioned balancing weight is a balancing weight that has the internal thread corresponding with the connecting rod screw thread, connecting rod has an end of nut and pre-installs this balancing weight, and the nut of this end is fixed on this balancing weight on the connecting rod on the connecting rod.
Also can be: the full flight screw of one one end band nut be fixed on fan blade on the motor shaft by two nuts that are in the motor shaft both sides that are positioned at screw rod one end, also screw rod self is fixed on the motor shaft simultaneously, above-mentioned balancing weight is a balancing weight that has the internal thread corresponding with screw flight, screw rod has an end of nut and loads onto this balancing weight in advance, this end nut fixed weight piece position on screw rod on the screw rod.
Adopt the technical solution of the utility model can reduce complete machine oscillation effectively, reduce the noise of complete machine widely, increase the reliability of using, increase the service life.It is according to being: analyze us by experiment and find that vibration and motor part relations are little, even we do the balancing rotor of direct-connected motor finely, isolated operation motor part, it is very steady, but when with still to produce vibration to having greatly after air compressor is connected, whether steady this explanation rotor influence of vibration to air compressor is very little, and vibrative main cause is: since piston in cylinder, move reciprocatingly produce, be because the rotor rotation, the eccentric steadily piece drivening rod of driving moves reciprocatingly piston and forms vibration in cylinder block, this vibration causes complete machine oscillation via two block bearing → stator cage → support → gas holder on cylinder block → motor shaft → rotor, this generation of vibration is inevitable, further analyze us, can see that this vibration is to produce and cause complete machine oscillation in cylinder, we are referred to as the A place with it, suppose that we then make a vibration source to make its amplitude and A place produce amplitude equal but direction is opposite in the B place at the other end, its as a result the amplitude of resultant vibration should be zero.So just can reach the purpose that reduces complete machine oscillation.For the convenience of producing in batches, its effectiveness in vibration suppression is a standard with the satisfaction of people's sense organ, so adopt scheme of the present utility model, the balancing weight of several grades of Different Weight of design can reach the effect that rapid realization reduces vibration by regulating.
The utility model is described in further detail below in conjunction with embodiment.
