Title:
ボールねじ機構用のスピンドル及びスピンドルを製造する方法
Document Type and Number:
Japanese Patent JP6632612
Kind Code:
B2
Abstract:
The invention relates to a method for producing a spindle for a ball screw, including the following steps: —introducing, at least in sections, a thread profile into a flat material section, —shaping the material section to a hollow cylindrical case, two lateral edges of the hollow cylindrical case abutting each other and the thread profile being oriented radially outwards, —connecting the two lateral edges of the hollow cylindrical case, and —forming, at least in sections, a supporting structure on a radially inner face of the hollow cylindrical case to finish the spindle. A spindle for a ball screw in hybrid design can thus be manufactured in a simple manner. The spindle can be produced cost-effectively and yet has high wear resistance and excellent mechanical load-bearing capacity as well as light weight. The invention further relates to a spindle manufactured according to the invention, for use in a ball screw.
