阅读说明：本技术 用于机床的机器主轴布置 (Machine spindle arrangement for a machine tool ) 是由 T.多恩 于 2018-03-14 设计创作，主要内容包括：根据本发明的机器主轴布置(22)形成了具有马达(19)作为中心元件的单元。在马达(19)的一个侧面处,具有主轴(32)的主轴颈(35)凸缘连接,所述主轴(32)由马达(19)的转子(28)直接驱动。主轴(32)是所谓的零位主轴,由于当前被精确调节的定位表面(39)(其邻接抵靠轴向适当限定的轴承接触表面(38)),因此可更换所述主轴(32),而不重新调节所有轴承和其它磨损部件。在马达(19)的背向主轴(32)的背面处,工具释放装置(20)和角度调节传动装置(21)被布置,用于使当前的横向进给轴(42)相对于主轴(32)旋转。横向进给轴(42)用于在工具(15)处致动调节装置。(The machine spindle arrangement (22) according to the invention forms a unit with a motor (19) as a central element. At one side of the motor (19), a main journal (35) with a main shaft (32) is flanged, which main shaft (32) is directly driven by the rotor (28) of the motor (19). The main shaft (32) is a so-called zero position main shaft, which main shaft (32) can be replaced without readjusting all bearings and other wear parts, due to the positioning surface (39) which is currently precisely adjusted, which abuts against an axially well-defined bearing contact surface (38). At the rear side of the motor (19) facing away from the spindle (32), a tool release device (20) and an angle adjustment transmission (21) are arranged for rotating the current infeed shaft (42) relative to the spindle (32). The infeed shaft (42) is used to actuate the adjustment device at the tool (15).)
