1.采用隔振措施,如使机床的电机与床身采用柔性联接以隔离电机本身的振动;把液压部分与机床分开;采用液压缓冲装置以减少部件换向时的冲击;采用厚橡皮、木材将机床与地基隔离,用防振沟隔开设备的基础和地面的联系,以防止周围的振源通过地面和基础传给机床等。
1. The isolation measures, such as the machine motor and lathe bed adopts flexible connection to isolate the vibration of the motor itself; to separate the hydraulic part and machine; the hydraulic buffering device to reduce commutation components impact. The thick rubber wood, the machine and foundation isolation, anti vibration ditch separated equipment foundation and the ground contact, to prevent around the source through the ground and foundation to machine tools.
2.避免激振力的频率与系统的固有频率接近,以防止共振。如采取更换电动机的转速或改变主轴的转速来避开共振区;用提高接触面精度、降低结合面的粗糙度;消除间隙、提高接触刚度等方法,来提高系统的刚度和固有频率。
2 the frequency of the exciting force is avoided and the natural frequency of the system is close to prevent resonance. Such as changing motor speed or change the spindle speed to avoid resonance region; by improving the precision of the contact surface, decreases the binding surface roughness; eliminate the gap, improve the contact stiffness of the, to improve the system stiffness and natural frequency.
3.减小或消除振源的激振力。对转速在600r/min以上的零件必须经过平衡,特别是高速旋转的零件,如砂轮,因其本身砂粒的分布不均匀和工作时表面磨损不均匀等原因,容易造成主轴的振动,因此对于新换的砂轮必须进行修整前和修整后的两次平衡。
3 reduce or eliminate the vibration source. The speed in above 600r / parts must be through the balance, especially in the high-speed rotating parts, such as wheel. Because of the uneven distribution of the sand and the work surface wear reasons such as uneven, easy to cause the spindle vibration, so the new change of the wheel must be trimmed and trimmed after two balance.
提高齿轮的制造精度和装配精度,特别是提高齿轮的工作平稳性精度,从而减少因周期性的冲击而引起的振动,并可减少噪声;提高滚动轴承的制造和装配精度,以减少因滚动轴承的缺陷而引起的振动;选用长短一致、厚薄均匀的传动带等。
To improve the manufacturing precision and assembly precision of gear, especially to improve the work of the stationary gear accuracy, so as to reduce the vibration caused by the impact of the cycle, and reduce the noise; improve the rolling bearing manufacture and assembly accuracy and to reduce the vibration caused by the rolling bearing fault; selection of the same length, thickness uniformity of transmission belt and so on.
