Embodiment Construction

[0026] figure 1 and figure 2 As shown, the amplitude self-adaptive rotating wheel provided by the present invention includes a rotating disc 1, an eccentric block 3, a spring 4 and a pin shaft 6, one end of the spring 4 is fixed on the rotating disc 1, and the other end is connected to the eccentric block 3 , the eccentric block shaft 7 is fixed on the rotating disc 1, the center of the eccentric block shaft 7 does not coincide with the center of the rotating disc 1, the hole of the eccentric block 3 is loosely fitted with the eccentric block shaft 7, and there is a pin on the rotating disc 1 Shaft hole 5, fixed pin 6.

[0027] When the rotating wheel starts to rotate, the rotating disk 1 is driven to rotate by the rotating shaft 2, and the rotating disk 1 drives the eccentric block 3 to move, and the centrifugal force generated by the eccentric block 3 does not pass through its axis, and generates a rotational moment on the axis of the eccentric block. Make the eccentric b...

Abstract

The invention relates to the field of vibration excitation equipment, in particular to an amplitude self-adaptive rotating wheel. The amplitude self-adaptive rotating wheel comprises a rotating disk, an eccentric block, a spring and a pin shaft and is characterized in that the shaft of the eccentric block is fixed on the rotating disk; the center of the shaft of the eccentric block is not coincident with the center of the rotating disk; the hole of the eccentric block is in loose fit with the shaft of the eccentric block; and a pin shaft hole is formed in the rotating disk for fixing the pin shaft. The amplitude self-adaptive rotating wheel has a large adjustable range and a large application range; and the self-adaptive capability to low frequency, low amplitude, high frequency and high amplitude can be achieved.

Description

technical field [0001] The patent of the present invention relates to the field of vibration equipment, and more specifically relates to an amplitude self-adaptive rotating wheel. Background technique [0002] For common inertial vibration equipment, its amplitude: [0003] [0004] Among them: m represents the excitation quality, r represents the eccentricity, M represents the vibration quality of the equipment, [0005] It can be seen from the formula that changing the amplitude can be done by changing the excitation mass m or changing the eccentricity r; [0006] At present, the vibration exciter commonly used has a constant amplitude during the working process. Changing the amplitude is by increasing or decreasing the mass of the eccentric block or changing the angle between the eccentric block. When the amplitude of the known eccentric weights is adjusted, the weight of the original eccentric weights is increased or decreased or the angle between the eccentric wei...
