Transmission module e.g. ball screw, has cooling circulation channel comprising flow inlet for supplying coolant and flow outlet for discharging coolant, and layer limiting groove comprising limiting base at circulation element

摘要

The module has a spindle (20) with a roll groove, and a screw nut (30) comprising a running surface that forms a loading path together with the groove. A circulation element (40) has a circulation path (42). Rolling elements (50) are arranged in the loading and circulation paths. A cooling device (60) is arranged at a body section (31) of the nut, and has an inner cooling circulation channel and a layer limiting groove (63). The channel has a flow inlet for supplying coolant and a flow outlet for discharging the coolant. The limiting groove has a limiting base (631) at the circulation element.
