用于在圆柱形孔表面上形成微观凹槽的装置以及通过使用该装置在圆柱形孔表面上形成微观凹槽的方法

Apparatus for forming microscopic recesses on a cylindrical bore surface and method of forming the microscopic recesses on the cylindrical bore surface by using the apparatus
Abstract:
An apparatus for forming recesses on a circumferential surface that defines a cylindrical bore in a workpiece includes a tool holder disposed coaxially with the cylindrical bore; a form roller support retained on the tool holder; a form roller rotatably supported on the form roller support, the form roller including projections on an outer circumferential surface thereof which are configured to form the recesses on the circumferential surface that defines the cylindrical bore in the workpiece. A control assembly is configured to control the form roller support such that the form roller is allowed to be in press contact with the circumferential surface that defines the cylindrical bore in the workpiece at a press contact load of a predetermined value on the basis of a centrifugal force which is exerted on the form roller support and the form roller during rotation of the tool holder.
Abstract(Chinese):

一种用于在圆周表面上形成凹槽的装置，其在工件中限定圆柱孔包括与该圆筒孔同轴设置的工具夹具; 保持在工具架上的成型辊支撑件; 可旋转地支撑在成形辊支撑件上的成形辊，所述成形辊在其外圆周表面上包括突出部，所述突出部构造成在所述圆周表面上形成在工件中限定圆柱孔的凹部。 控制组件被配置为控制成形辊支撑件，使得成形辊被允许在基于离心力的预定值的压力接触负载下与形成工件中的圆柱形孔的圆周表面压力接触 在工具架旋转期间施加在成形辊支撑件和成形辊上的力。
