Embodiment Construction
[0012] Such as figure 1 The vertical lathe workbench shown involves a turntable 5 and a base 4, and the bottom surface of the turntable 5 and the upper surface of the base 4 are compounded with a zinc alloy wear-resistant plate 1 to increase the service life of the workbench. The main shaft 3 is set in the base 4 through the bearing, the upper end of the main shaft 3 is fixedly connected with the turntable 5, the lower end of the main shaft is equipped with a bearing 9, the bottom end of the main shaft 3 is connected with the reducer, and the outer diameter of the joint between the main shaft 3 and the base 4 has a taper. 3182100 type double-row cylindrical roller bearing 7 with tapered inner ring 6 is installed at the place with taper. Adjusting nut 8 is set on the main shaft 3. The adjusting nut 8 is close to the small inner diameter end of bearing 7. Adjusting nut 8 and tapered bearing 7 Adjusting spacers 2 are installed between them.
