Problems solved by technology

In order to achieve a better vibration effect, the required vibration intensity is relatively large. When the exciter is working, the shaft and the shell of the exciter are vibrating. On the one hand, it brings a large dynamic load to the bearing installed on the shaft of the exciter. Reduce the service life and reliability of the bearing. On the other hand, in order to avoid the adverse effects of vibration on other parts of the machine, it is necessary to increase the vibration damping mechanism, which not only increases the difficulty of design, but also leads to a complex overall structure of the machine and an increase in cost.

Embodiment Construction

[0018] Such as figure 1 As shown, the vibrator is composed of a housing 1, a bearing 2, a balance weight 3 and an eccentric shaft 4. Both ends of the eccentric shaft 4 are sleeved with bearings 2, the housing 1 is fixedly connected to the bearing 2, the balance weight 3 is fixedly connected to the eccentric shaft 4 according to the dynamic balance condition, and the eccentric shaft 4 is connected to the power source through transmission. When the exciter is working, the eccentric shaft 4 rotates at a high speed to vibrate the housing 1, and the centrifugal force generated by the high-speed rotation of the balance weight 3 offsets the dynamic load generated by the housing 1 on the eccentric shaft 4, ensuring that the eccentric shaft 4 maintains dynamics when rotating at high speed. balance. The vibration generated by the exciter is directly transmitted to the working medium by the shell 1, and the eccentric shaft 4 that meets the dynamic balance condition does not vibrate, whi...

Abstract

A vibration exciter for the building mechineries, such as vibration stirrer and vibration compactor, is composed of an eccentric shaft, bearings, casing connected via bearing to said eccentric shaft, balancing weights symmetrically connected to said eccentric shaft, and power source for driving said eccentric shaft. Its advantages are simple structure, high vibration effect and long service life.

Description

Technical field [0001] The invention provides a vibration exciter design method for construction machinery, which is used in a vibrating stirring device and a vibrating compacting device. Background technique [0002] Vibration stirring and vibration compaction are used in engineering construction, and its main advantage is high efficiency. The vibration of these vibrating machines is realized by corresponding exciters. The vibration of the existing vibrator is generated by the rotation of an eccentric mass on the shaft of the vibrator. In order to achieve a better vibration effect, the required vibration intensity is relatively large. When the exciter is working, the shaft and the shell of the exciter are vibrating. On the one hand, it brings a large dynamic load to the bearing installed on the shaft of the exciter. Reduce the life and reliability of the bearing. On the other hand, in order to avoid the adverse effects of vibration on other parts of the machine, it is nec...
