The utility model relates to a motor shock absorbing device of a main shaft of a precision grinding machine. A feeding worktable (2) is connected with a table top of a machine tool body, a main shaft (1) is connected with the feeding worktable, and a large belt pulley (7) is fixedly connected with the main shaft. The utility model is characterized in that the large belt pulley is connected with a plurality of wedge belts (6) with thin belt bodies, good flexibility, small shock and stable transmission, the wedge belts are connected with a small belt pulley (5) which is fixedly connected with a shaft of the driving motor, and the driving motor (3) is fixed in a cast machine tool body (4). The utility model can effectively absorb and damp shock to assure that the rotary precision of the main shaft of a precision grinding tool is not influenced by the motor to a maximum extent.
