Transmission gear box structure of grinding machine

The transmission gear box structure of the grinding machine comprises a gear box body, the center of an inner cavity of the gear box body is rotationally connected with an input transmission shaft with the upper portion penetrating out of the gear box body, and four output transmission shafts with the lower portions penetrating out of the gear box body are evenly distributed on the periphery of the inner cavity of the gear box body. The input transmission shaft synchronously drives the four output transmission shafts through a gear pair, and the four output transmission shafts rotate in the same direction. The gear box is favorable for improving the grinding efficiency and reducing the failure rate. 本实用新型涉及一种研磨机传动齿轮箱结构，包括齿轮箱箱体，所述齿轮箱箱体的内腔中心转动连接有上部穿出齿轮箱箱体的输入传动轴，齿轮箱箱体的内腔周部均布有四根下部穿出齿轮箱箱体的输出传动轴，所述输入传动轴经齿轮副同步驱动四根输出传动轴，且四根输出传动轴同向旋转。该齿轮箱有助于提高研磨效率，减少故障率。
