Vibration reducing device with noise reduction mechanism

Abstract

The invention discloses a vibration reducing device with a noise reduction mechanism. The vibration reducing device comprises a bearing plate, the bearing plate is elastically connected with a fixed plate through first springs, the bottom end of the fixed plate is fixedly connected with two fixed blocks, guide grooves are formed in the fixed blocks, the bearing plate is fixedly connected with a fixed rod, the fixed rod is sleeved with a movable sleeve, and the movable sleeve is elastically connected with the bearing plate through a second spring. According to the vibration reducing device withthe noise reduction mechanism, when vibration is transmitted from the bearing plate to the fixed plate, the first springs between the bearing plate and the fixed plate can reduce the vibration transmitted to the fixed plate, when the vibration in the horizontal direction is received, first limiting blocks move to one side close to or far away from the fixed rod and can drive connecting rods to rotate, the movable sleeve slides along the fixed rod, the connecting rods rotate around the hinged points of the connecting rods and the movable sleeve, and due to the fact that the movable sleeve is elastically connected with the bearing plate through the second spring, vibration can be reduced through the second spring and third springs, and the buffering effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of mechanical electromechanical damping equipment, in particular to a damping device with a noise reduction mechanism. Background technique [0002] When the mechanical and electrical processing equipment is running, it will generate large vibration, which not only affects the stability of the operation of the equipment and the accuracy of processing, but also damages the ground and reduces the service life of the device. A good shock absorption device can not only ensure the smooth operation of the mechanical equipment, reduce the noise during the operation of the equipment, but also greatly reduce the maintenance and repair costs of the mechanical equipment. [0003] The existing mechanical and electromechanical shock absorption equipment generally adopts multiple symmetrical or evenly distributed vertical guide structures. However, in actual operation, the vibration force is very complex. The vibr...

Problems solved by technology

[0003] Existing mechanical and electrical shock absorbing equipment generally adopts multiple vertical guide structures that are symmetrical or evenly distributed around the circumference. However, in actual operation, the vibration force is very complicated. The vibration source of the equipment is often not in the center of the equipment, and local frequent Vibration leads to an increase in the radial force gap between the guide structure close to the vibration source and the guide structure far away from the vibration source. When the vibration source is located at the end of the equipment, it is more likely to cause serious unbalanced vibration of the equipment. Long-term work is likely to cause damage to the shock-absorbing structure and cause serious vibration. loud noise
