Title: Noise reducing device for construction machine
Inventor: NISHIKAWA KENJI
IPC: G10K11/16
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce the vibration to reduce the noise by separately bonding the laminates manufactured by laminating the plates at specific intervals on a part or the whole of a noise generation part of a construction machine. SOLUTION: A predetermined number n1 of thin ordinary steel plates 8 are laminated on a rear side of a track block 1, and the laminates of n1 sheets are bonded to a plurality of spots of the track block 1 by plug welding W. When the track block 1 is vibrated, the laminates 8 are respectively vibrated corresponding to the restricting condition such as the bonding intervals and the like, and the fine dislocation and gap are generated among the plates. In accompany with the vibration, these fine dislocation and gap are successively and variably generated at all times, so that the friction and collision are repeated among the plates. Whereby the vibration energy of the track block 1 is converted into the heat energy by the friction and collision, and dissipated. That is, the vibration of the track block 1 can be reduced, and the noise generated from the track block 1 can be reduced.
