The thin oil shaker is a new type of exciter device that is often used as an auxiliary device for other mechanical equipment to provide exciting force. This thin oil shaker becomes the main component of the mechanical vibration. In a thin oil shaker, the exciter can obtain a certain amount of vibration through a thin oil exciter, thereby driving the operation of the mechanical device.
The thin oil exciter is mainly used for stimulating the excited object, so that the excitation device shell is kept basically stationary during the excitation, so that the energy of the exciter is used as much as possible. The motivation of the excited object. For this reason, the vibration exciter is installed to meet this requirement. When a higher frequency excitation is required, the thin oil exciter is suspended with a soft spring and the necessary counterweight can be added to minimize the natural frequency of the suspension system so that its natural frequency is lower than the excitation frequency. /3 or more. At low frequency excitation, the exciter is rigidly mounted on the ground or on a rigid rack, and the natural frequency of the installation is more than three times higher than the excitation frequency. In many cases where the reference for the vibration exciter cannot be found, the exciter can be spring supported on the excited object. This method is only applicable to the vibration test in which the mass of the excited object far exceeds the mass of the thin oil exciter and the excitation frequency is greater than the natural frequency of the exciter installation.
Because the torque and vibration of the thin oil exciter during operation are large, the failure of the transmission system, such as the bearing parts and the wear of the bearing chamber, often occur. Therefore, in daily use, we should carry out regular inspection and maintenance of the thin oil shaker, so that the service life of the thin oil shaker is longer.
