US08623228B2 Freely mounted wheel set made of micro-machinable material and method of fabricating the same 有权
由微加工材料制成的自由安装的轮组及其制造方法

Freely mounted wheel set made of micro-machinable material and method of fabricating the same
Abstract:
The invention relates to a gear train (51, 51′) including an arbour (53, 53′) a first end of which is fitted with an integral collar (52, 52′), a first wheel set (55, 55′) made of micro-machinable material being fitted onto the second end of the arbour (53, 53′). According to the invention, the gear train (51, 51′) includes a second wheel set (57, 57′) made of micro-machinable material, which is independent of the movements of said first wheel set and which includes an aperture (58, 58′) whose wall is mounted opposite said arbour so that the second wheel set (57, 57′) is freely mounted on said first end of the arbour (53, 53′).
Abstract(Chinese):

本发明涉及一种包括心轴（53,53'）的齿轮系（51,51'），该心轴（53,53'）的第一端装有整体式套环（52,52'），第一轮组（55,55'） 由微加工材料制成，安装在心轴（53,53'）的第二端上。 根据本发明，齿轮系（51,51'）包括由微加工材料制成的第二轮组（57,57'），其与所述第一轮组的运动无关，并且包括孔（58 ，58'），其壁相对于所述心轴安装，使得所述第二轮组（57,57'）自由地安装在所述心轴（53,53'）的所述第一端上。
