Abstract
Eccentric block rotatable or shiftable to rotating shaft is adopted in the disclosed motor instead of eccentric block fixed on rotating shaft in former type of motor. Thus, when starting angular frequency of motor exceeds natural frequency of vibrating machine system, moment of the eccentric block just reaches to a rated value from small value. In time of stopping a motor, when angular frequency of motor starts to be dropped but still is higher than natural frequency of vibrating machine system, the eccentric block is recovered back to initial position. Through a pair of eccentric block, which are engaged at initial time, and disengaged then at running time, makes a motor generate rectilinear vibration and obtain double exciting force. If a vibration shaft coupling is adopted, then big varieties of distance and angle of centerline can be adapted so as to reduce exciting force, and protect motor.
Description
Technical field
The invention belongs to vibrating motor, particularly the light-load start-stop energy-saving vibration motor.
Background technology
Eccentric block formula vibrating motor is mainly used on the vibrating machines such as vibrating screen, oscillating feeder, jigging conveyer, vibration milling, plain bumper.At present; eccentric block formula vibrating motor mainly contains the deficiency of following three aspects on the market: the one, and eccentric block all is to be fixedly connected in the rotating shaft; its torque is starting; operation; all be constant in the stopped process; for obtaining bigger detent torque; certainly will select more powerful motor; in order to make vibrating machine obtain stable amplitude; the nominal operation angular frequency of eccentric block all is greater than the natural frequency of several times vibrating machine; when electric motor starting; the angular frequency of eccentric block will be by the natural frequency of vibrating machine system in the middle of when zero reaches the nominal operation angular frequency; when motor is shut down; the angular frequency of eccentric block also will be by the natural frequency of vibrating machine system in the middle of when the nominal operation angular frequency drops to zero; when the angular frequency of eccentric block equates with the natural frequency of vibrating machine system; cause the resonance of vibrating machine system; the useful life that resonance has reduced vibrating machine and motor, and there is very big destructiveness on the basis, but also produce very big noise.Resonance also makes the feed precision of oscillating feeder restive; The 2nd, in needing the vibrating machine of straight-line oscillation, need two vibrating motors in parallel, power consumption is big, the cost height, must the right patent No. be: the utility model patent of ZL200320104185.8 only just can realize straight-line oscillation with a motor, but exciting force still can not replace two motors; The 3rd, in motor and separated type vibrating motor that eccentric block is connected by shaft coupling, shaft joint is selected Hooks coupling universal coupling and flexible clutch usually for use, the former can only compensate the angle of two axial lines, and can not compensate the bigger translation of two axial lines, the latter, the non-metallic part non-refractory is easy to damage, and motor still had bigger axial force and radial load, motor and basis there are bigger infringement.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of said fixing eccentric block formula vibrating motor; and the eccentric block that a kind of novelty is provided with the angular frequency difference the different vibrating motor of centroid position; its eccentric block opens at motor; the torque that stops in the process is very little; make vibrating machine system underloading; open reposefully; stop; avoid starting with stopping process in covibration; and when needs straight-line oscillation; the straight-line oscillation that only needs a motor just can produce the exciting force that is equivalent to two equal-wattage motors generations, and the shaft coupling that provides also can compensate the variation of two axial line distances and angle significantly.
The technical solution adopted for the present invention to solve the technical problems is: the one, the former eccentric block that is fixed in rotating shaft is made into the eccentric block of or displacement rotatable with respect to rotating shaft, when motor is static, the barycenter of eccentric block is near the axle center, has only very little torque, when motor just starts low speed rotation, because the positioning action of positioner and the elastic force of back-moving spring make the eccentric block initial moment constant on the eccentric block, when motor angle of rotation frequency reaches set point, when promptly substantially exceeding the natural frequency of vibrating machine system, after the centrifugal force of eccentric block barycenter is enough to overcome the elastic force of the positioning action power of positioner and back-moving spring, the barycenter of eccentric block and distance of shaft centers are from being increased to desired location, the moment of eccentric block reaches maximum, give the exciting force of vibrating machine maximum, and positioner is also arranged in this position, smooth change is not to the influence of eccentric block position to avoid angular frequency, and holding torque is stable.During shutdown, when the angular frequency of motor drops to set point but still during greater than the natural frequency of vibrating machine system from maximum, the elastic force of back-moving spring returns to initial position with eccentric block, at this moment, the eccentricity of eccentric block is very little, when the angular frequency of motor rotation passed through the natural frequency of vibrating machine system, the vibrating machine system can not produce covibration; The 2nd, use eccentric block in pairs, engagement when this has just begun by a pair of rotation with a motor eccentric block, along with eccentric block moment increases and the gear that separates comes transmission, make this produce the synchronous backward motion and make the vibrating machine system produce straight-line oscillation, and obtain double exciting force eccentric block; Three are to use the shaft coupling of crosshead shoe, cross bearing pin and spline combination, can satisfy the compensation of axial line distance, the big variation of angle.
The present invention compared with prior art; its advantage is: motor light-load starting, shutdown, avoided the resonance that opens, stop producing in the process, and prolonged the useful life of equipment; and can produce straight-line oscillation with a motor; and be equivalent to two exciting forces that produce with the motor of constant power, and saved electric energy, reduced cost; under the independent installation situation of motor; alleviated the vibrating machine system to motor and basis thereof axially, exciting force radially, help protecting motor, prolonged the useful life of motor.
