Online dynamic balance device of emery wheel

The utility model discloses an online dynamic balance device of emery wheel, including emery wheel axle, emery wheel cover and emery wheel the emery wheel in the middle of install balanced spacer ring, balanced spacer ring hug closely the emery wheel face, compress tightly through the clamp plate between the emery wheel balanced spacer ring in install the balancing piece, the balancing piece can remove on balanced spacer ring place plane. The beneficial effects of the utility model are that: can reduce the heavy of online dynamic emery wheel to below the numerical value of ideal fast, reducingeffectively under the heavy circumstances of a preceding emery wheel, also can take into account the heavy of the emery wheel in back, greatly improve the quality of bearing race grinding. 本实用新型公开了种砂轮在线动态平衡装置，包括砂轮轴、砂轮套以及砂轮，在所述的砂轮中间安装有平衡隔圈，所述的平衡隔圈紧贴砂轮面，砂轮之间通过压板进行压紧，在所述的平衡隔圈内安装有平衡块，所述的平衡块可以在平衡隔圈所在平面移动。本实用新型的有益效果是：可以快速地将在线动态砂轮的偏重降低到理想的数值以下，在有效地降低前面块砂轮偏重的情况下，也可兼顾到后面块砂轮的偏重，极大地提高轴承滚道磨削的质量。
