Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0041] like Figure 4~8As shown, the vibrator in the present invention includes an excitation shaft and an eccentric mass. The excitation shaft includes a central rotating shaft 12 and an outer ring rotating shaft 13. An axial through hole is arranged in the outer ring rotating shaft 13, and the central rotating shaft 12 is placed in the outer ring. In the rotating shaft 13, the central rotating shaft 12 and the outer ring rotating shaft 13 are arranged coaxially. This shaft will be replaced by "axis 9" in the following expressions. Two first eccentric blocks 10 are arranged on the side wall of the central rotating shaft 12, and the two first The eccentric block 10 is arranged on the same side of the axis 9; two second ecce...

Abstract

The invention relates to a vibration exciter and a using method thereof. The vibration exciter comprises a vibration exciting shaft and an eccentric block, wherein the vibration exciting shaft comprises a central rotating shaft and an outer ring rotating shaft, the outer ring rotating shaft sleeves an axial through hole, the central rotating shaft is arranged in the axial through hole of the outerring rotating shaft, the central rotating shaft and the outer ring rotating shaft are coaxially arranged, the central rotating shaft is provided with first eccentric blocks, and the outer ring rotating shaft is provided with second eccentric blocks. When the vibration exciter is started, the excitation force is zero, the vibration exciter can be started stably, after the vibration exciter reachesa rated rotation speed, required excitation force and amplitude can be obtained by adjusting the relative position angle of the eccentric blocks, before vibration equipment is stopped, the excitationforce is adjusted to be zero to realize stable stop.

Description

technical field [0001] The invention relates to an excitation device, in particular to an exciter and a method for using the exciter. Background technique [0002] As a main working part of vibration equipment, the performance of the exciter has a great influence on the working performance of the whole equipment. Vibration equipment has been widely used in mines and metallurgical plants, coal preparation plants, chemical plants, power plants, foundries, construction sites, cement plants, and grain and food processing plants, such as vibrating feeders, vibrating screens, vibrating centrifuges Dewatering machine, vibration molding machine, vibration ramming machine, vibrator, vibratory roller, vibration test bench, etc. According to statistics, there are hundreds of uses and types of vibration equipment, and they play a very important role in all aspects of industry, agriculture, national defense and human social life. [0003] When the vibrator is working, the size of the e...
