It further include only pressure device, the upper end of firm banking is arranged in the only pressure device, for adjusting the position of shock absorbing device
It moves.
The pretightning force of the flexible adjustment device according to the flexible adjustment of main elastomer block and secondary elastomer block.
The elasticity of the main elastomer block is greater than the elasticity of secondary elastomer block, and the main elastomer block has muti-piece main regulation elastomer block layer
Folded to form, the pair elastomer block bottom end is equipped with groove, is equipped with amplitude in the groove and adjusts pearl.
The support device is mounted on the maximum position of motor oscillating, and is mounted in the principal direction of motor oscillating
The elasticity of the only pressure device is greater than the elasticity of main elastomer block.
Damping device of the invention on motor by installing, to change the vibration performance of motor, to inhibit motor
Vibration.Traditionally use simple packing, the damping effect of motor is not obvious, the present invention change it is traditional only with
Method, the vibration of motor body is reduced using shock absorbing device, i.e., electricity is reduced by the vibration of elastomer block in shock-absorbing means
The vibrational energy of machine changes the frequency that maximum vibration occurs for motor, can change the vibration performance of electric system from source.Have
Effect reduces the vibration of motor, inhibits the vibration of motor body vibration and unit, so that fatigue failure caused by motor oscillating is solved,
Improve the reliability of complete machine.
Detailed description of the invention
Fig. 1 motor shock-absorbing device schematic diagram.
