发明名称 Shaft cooling for a machine tool motor spindle
摘要 <p>The cooler has a rotating shaft, a static lance (4), and a cooling circuit, which is comprised of a coolant inlet (5) and a coolant outlet (6). The shaft is cooled by cooling holes with a coolant, where the cooler is formed in such a manner that introduction of the coolant into the lance is taken place via the cooling holes from inside to outside in the shaft. Mediums are supplied into the lance, and the coolant is loadable with a centrifugal force. Lip seals (33) are symmetrically arranged at the lance, which delivers the coolant.</p>
