- a pendulum consisting of a weight is axially supported on a pulley shaft of an exciter, and the pulley shaft is driven and rotated by the motor via a belt. And the vibration is transmitted to the rolling plate for rolling.
- the belt is stretched between the pulleys on the prime mover side and the exciter side.
- the distance between the axes of the two pulleys fluctuates greatly with the rotation of the pendulum, so that a strong rippling motion occurs in the belt and the belt The wear and tear was remarkable.
- the belt of a vibratory compressor with vibration of 80 Hz to 100 Hz was under very severe conditions, so the amplitude of the pressure plate was limited to 1.5 to 1.9 mm.
- the compactor plate including the exciter and the prime mover are coupled via the rubber damping rubber, and the damping rubber absorbs the vibration of the compactor plate, thereby separating the prime mover from the vibration of the compactor plate.
- the mass on the exciter side including the prime mover side and the rolling bearing plate separated via the anti-vibration rubber is approximately equal, or the mass on the prime mover side is large!
- Patent Document 1 Japanese Patent Application Laid-Open No. 2000-192416
- the fluctuation of the distance between the motor and pulleys due to the rotation of the pendulum is reduced to eliminate the adverse effect on the belt and the vibration damping due to the internal resistance of the vibration damping. In order to generate sufficient vibration.
- the present invention comprises a rolling contact plate, a prime mover and a vibrating body, the prime mover is mounted on the rolling contact plate via the vibration isolation means, and the vibrating body is fixedly arranged on the rolling contact plate.
- the body is provided with a coaxially supported pulley and a pendulum, and the pulley on the exciter side is connected via a belt to a pulley connected to the output shaft of the motor, and the pulley on the exciter side is an axis of the pendulum.
- the pulley is eccentrically supported on the pulley shaft so that the center of the pulley is located on the center of gravity of the pendulum, and the eccentricity of the pulley on the exciter side is 1Z2 of the amplitude of vibration.
- the amplitude of vibration means both amplitudes.
- the width of vibration means both amplitudes.
- the rolling bearing plate, the prime mover and the exciter force are mounted on the rolling bearing plate via the vibration damping means, and the vibrating body is fixedly arranged on the rolling bearing plate, and the vibrating body is coaxial
- the pulley on the exciter side is connected via a belt to a pulley connected to the output shaft of the prime mover, and the anti-vibration rubber and metal bar are arranged in parallel on the roller plate. It is characterized in that the prime mover is supported via the anti-vibration means which also becomes the combined force of the ne.
- the rotation and vibration are 180 ° when the number of rotations exceeds a certain number of rotations.
- the pulley is substantially at rest, the distance between the motor and the pulley shaft is stabilized, the belt waving phenomenon is eliminated, and the belt is not worn, damaged or broken. can do.
- the prime mover side and the rolling contact plate are connected via the anti-vibration means which is a combined force of anti-vibration rubber and metal panel disposed in parallel, and the weight of the non-drive rubber side is jointly It is possible to suppress the damping of the vibration due to the internal resistance of the vibration-proof rubber, obtain vibration with large vibration speed, acceleration and amplitude, and increase the rolling pressure with good working efficiency. , A large amplitude oscillator can be obtained.
- (1) shows the vibratory compressor according to the present invention
- (2) is a prime mover, and is mounted on the roller pressure plate (3) via the anti-vibration rubber (4) and the metal panel (5).
- (6) is an exciter, which comprises a pulley (7), a pendulum (8) consisting of a weight, and a pulley shaft (9) for supporting the same, and is fixed on the roller plate (3) .
- the pulley (7) on the exciter side is linked to the pulley (11) on the motor side via the belt (10), and the driving force is transmitted.
- the motor-side pulley (11) is preferably connected to the output shaft of the motor via a centrifugal clutch.
- the belt is preferably a V-belt.
- the present invention is directed to an exciting type electrical contactor (1) in which a pulley (7) on the exciter side is eccentric to its center (7c) and the pulley shaft ( It is characterized in that it is supported by 9).
- the amount of eccentricity (C) from the center (7c) of the pulley to the pulley shaft (9) is 1Z2 of amplitude.
- the eccentric direction is such that the center (7c) of the pulley is located on the center of gravity (8a) of the pendulum with respect to the axis of the pendulum.
- the unstable state at the start is exceeded and a constant rotation range (vibration range)
- a constant rotation range vibration range
- the rotation and the vibration that is, the rotation of the pendulum (8) and the vibration of the exciter (6) are phase-shifted by 180 ° and become a constant swing width (both amplitudes). Therefore, by offsetting the pulley on the exciter side by 1Z2 of this swing width (both amplitudes), the pulley is kept in the positional relationship of the stationary state.
- the swing width is set to 2.4 mm
- the eccentricity amount is set to 1 ⁇ 2, 1.2 mm.
- FIG. 2 (a) shows a stationary state, and the center (7c) of the pulley (7) is eccentric by an eccentricity amount C with respect to the pulley shaft (9).
- the motor is in an unstable rotation state, but when it reaches a fixed rotation range (vibration range) beyond this unstable state, the rotation of the pendulum and the vibration of the exciter cause a 180 ° phase shift, The amplitude of the vibration becomes harmonic vibration.

- the rotation center of the pulley (7) coincides with the axis of the pulley shaft (9) in the stationary state as shown in FIGS. 2b to 2e, and is in the stationary state. Since the axial distance between the pulley (11) on the motor side and the pulley (7) on the exciter side is substantially stationary with no fluctuation, it is bridged between the two pulleys. It is possible to avoid damage or breakage of the belt which may cause the occurrence of a wave phenomenon or the like on the belt (10).

Even if the metal panel is arranged on the outer periphery of the vibration-proof rubber, the metal panel is The It is good also as a structure inserted. As described above, by providing the support structure combining the anti-vibration rubber and the metal panel, the amplitude of the exciter also increases, so the transfer pressure increases, the forward speed at the time of the compression also increases, and the work efficiency is good. Become. As a result, the mass of the upper structure is not limited, and the oscillating rolling pressure and efficiency can be generated in line with the original design concept.
