摘要： A method of mounting a rotary scale member on a machine part which is configured to rotate about an axis of rotation. The rotary scale member comprising a body on which a series of scale features defining a scale that extends around a scale axis is or can be provided, and at least three radially-compliant flexures spaced around said scale axis. The method comprises: i) locating the rotary scale member on the machine part such that the scale axis and axis of rotation are substantially parallel, and ii) subsequently arranging at least a first radial adjustment device so as to contact both the machine part and the rotary scale member, and manipulating the at least first radial adjustment device so as to radially displace the body of the rotary scale member. At least the majority of any radial reaction force, generated as a result of the interaction of at least one of said flexures with a radial stop member against which it is radially pressed, and which is imparted on the at least first radial adjustment device by the rotary scale member in opposition to said radial displacement of the rotary scale member, is directed into, and reacted by, the machine part via the contact between the at least first radial adjustment device and the machine part.

摘要： A method of mounting a rotary scale member on a part (e.g. of an articulated joint), the rotary scale member comprising a body on which a series of position features defining a scale is provided, and at least one mounting flexure configured to engage the part, the method comprising: force-fitting the rotary scale member and the part together, whereby the at least one flexure is displaced by the part and thereby urged via a radial reaction force into engagement with the part so as to form a friction fit with the part such that the body of the rotary scale member self- locates at an initial default radial location with respect to the part; and tweaking the radial location of the body relative to the part away from its initial default radial location to a new radial location.
