Abstract

The invention relates to a high speed spindle balancing device, in particular to a high speed spindle inline dynamic balancing device. The invention solves the defects and deficiency of existing high speed spindle inline dynamic balancing device, particularly indirect inline dynamic balancing device and mixed model inline dynamic balancing device. The invention includes a slide disk seat with a ferromagnetic material layer arranged on the central circle surface, an indirect inline dynamic balancing mechanism of a stator, a stator and a transducer fixed to the stator, slide disks sleeved at both ends of the slide disk seat, and a balancing weight block fixed to the slide disk, a mixed model inline dynamic balancing mechanism of pressure plate fixedly sleeved on the main shaft and touches with the slide seat and slide disk end surface; an electromagnetic winding is arranged by one side of the pressure board, one end surface of the pressure board is coated with ferromagnetic material layer, a sleeve is fixedly arranged on the main shaft on one side of the pressure board, an elastic component sleeved on the main shaft is arranged between the sleeve and the pressure board. The balancing device is characterized by short response time and energy saving as inline dynamic balancing compensation effect for a high speed spindle.

Description

technical field [0001] The invention relates to a high-speed spindle balancing device, in particular to an online dynamic balancing device for a high-speed spindle. Background technique [0002] Rotating machinery such as compressors, turbo generators, boiler induced draft fans, large motors, etc. are moving towards high speed. The high-speed spindles of these rotating machines are mainly concerned with vibrations based on unbalanced quantities. The amount of vibration is proportional to the second power of the rotation speed, and it will cause damage to the rotation system or the entire system when passing through high speed. Therefore, it is necessary to dynamically balance the high-speed spindle. At present, the main balancing measures are off-line dynamic balancing, that is, the size of the unbalance is measured through the test, and the counterweight is added or removed when the machine is stopped. Because off-line dynamic balancing is a downtime operation, it will c...
