Referring to fig. 1 to 4, an embodiment of the present application provides a precision heavy-duty cup, which includes a base 1, a bearing ball set 2, a screw 3, and a nut 4. Wherein, the base 1 is provided with a mounting through hole 11. The bearing ball group 2 is arranged on the base 1, and the bearing ball group 2 is arranged outside the mounting through hole 11 in a surrounding manner. The screw rod 3 is matched in the mounting through hole 11 of the base 1, and the screw rod 3 is in sliding fit with the bearing ball group 2. The nut 4 is disposed on the screw rod 3. The screw rod 3 is provided with joint 5 with base 1 complex tip.
According to the precise heavy-load cup provided by the embodiment of the utility model, the bearing ball group is arranged between the screw and the base, the shaft ring and the seat ring of the thrust bearing are removed, only the middle bearing roller group (ball/roller and retainer) is reserved, the screw is used for replacing the shaft ring, and the base is used for replacing the seat ring, so that the rotation of the cup under the heavy load condition can be easily adjusted, and the structure of the cup is simplified. The precise heavy-load foot cup is suitable for heavy precision equipment, electronic equipment, instrument instruments and other equipment.
In one embodiment, the base 1 and the screw rod 3 are provided with grooves, and the bearing ball group 2 is arranged in the grooves. Through all setting up the recess on base 1 and screw rod 3 for bearing ball is more stable when cooperating with screw rod 3 and base 1, and the difficult off tracking of bearing ball.
