Non-rotating sleeve rotation preventing device and rotation guiding device

摘要

An anti-rotation device for a non-rotating sleeve, wherein the anti-rotation device is connected to the non-rotating sleeve so as to transmit a circumferential acting force to the non-rotating sleeve to prevent rotation of the non-rotating sleeve. , An anti-rotation member and an elastic member, wherein the anti-rotation member can move substantially in the radial direction of the non-rotational sleeve, and the elastic member acts on the anti-rotation member and is substantially radially outwardly directed to the anti-rotation member. Of action. The present application provides a non-rotating sleeve anti-rotation device and rotation guidance device, which in one aspect provides a basis for accurate attitude measurement and guidance control, and in another aspect, one anti-rotation device Using only one, it is possible to achieve high speed rotation of the two non-rotating sleeves, while at the same time the anti-rotation device can further provide an inductive driving force based on minimum structural dimensions It is.
