摘要（英）：

The invention relates to a main spindle box of an LDCK5150 numerical control vertical lathe, in particular to a main spindle box of a numerical control vertical lathe for specially processing large-scale wind-powered wind tower flanges and ring forgings. The main spindle box is characterized by adopting a rolling bearing which is installed on a main spindle and is partitioned in the middle by a supporting sleeve; the tail of the main spindle is provided with a screw thread and a pin cap; the main spindle, rolling bearings, the supporting sleeve and the pin cap are installed in the middle of a bearing seat which is installed on a base of a worktable and connected by bolts; and the main spindle is connected with the worktable by bolts. The invention has simple, compact and reasonable structure, convenient and rapid installation, high assembly precision, accurate position, low manufacture cost of parts, and convenient and practical control for radial clearance and jumping.
