摘要： A double-bearing position encoder has an axle stabilized within a housing via two bearings disposed on opposite walls of the housing. The axle is in communications with a rotating cam. The cam actuates a pulser so as to generate an active pulse at a tissue site for analysis by an optical sensor. The axle rotates a slotted encoder wheel or a reflective encoder cylinder disposed within the housing so as to accurately determine the axle position and, hence, the active pulse frequency and phase.

摘要： The present disclosure provides a collaborative robot arm and a joint module. The joint module includes a housing, a driving assembly, and a multi-turn absolute encoder. The joint module detects the angular position of the output shaft and records a number of rotating revolutions of the output shaft only by means of the multi-turn absolute encoder. The multi-turn absolute encoder includes a base, a bearing, a rotating shaft, an encoding disk, and a circuit board, the encoding disk is rotatably connected with the base by the rotating shaft and the bearing, the circuit board is fixedly connected with the base, and the reading head on the circuit board detects the angular position of the output shaft cooperatively with the encoding disk, making the multi-turn absolute encoder be an integrated structure. The base and the rotating shaft are detachably connected with the housing and the output shaft respectively.

摘要： A retaining device for coupling an encoder unit of a rotary encoder to an electric machine includes an end shield having a guide groove for receiving an encoder module of the encoder unit, and a retaining ring including a first coupling element for mechanically coupling the retaining ring to the end shield, with the first coupling element being embodied as a hole. A fastening screw is received in the hole to mechanically fasten the retaining ring to the end shield. A shielding element is integrally formed on the retaining ring for shielding against an external interference field.

摘要： A method of mounting rotary scale member on machine part includes: locating rotary scale member on machine part such that scale axis and axis of rotation are substantially parallel, and subsequently arranging at least a first radial adjustment device to contact both machine part and rotary scale member, and manipulating the at least first radial adjustment device to radially displace body of rotary scale member. At least the majority of any radial reaction force, generated as a result of the interaction of at least one of the 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 rotary scale member in opposition to the 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, the rotary scale member including 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 including: 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.

摘要： A rotary encoder for a valve comprises a rotatable code plate and an optical detector module comprising one or more optical detectors. The code plate defines a set of voids arranged along a set of one or more concentric circular arcs about an axis of rotation. The voids define an angle-dependent pattern over the set of arcs, the pattern comprising a plurality of distinct sectoral elements (A-O, X). At least two of the sectoral elements, located in non-adjacent sectors of the code plate, are identical, but the pattern is non-repeating over a single full rotation of the code plate about the axis. Each optical detector is aligned with a respective concentric circular arc of the code plate. A controller processes time-varying output signals from the optical detectors to determine successive positions of the rotatable code plate.

摘要： A reflective optical encoder (40) assembly includes a motor and brake assembly at least partially in a motor and brake housing (42). An encoder housing is at least partially received in a cavity (34) of the motor and brake housing. The reflective optical encoder includes an encoder disk (50) and an encoder shaft (44) that rotate with a shaft of the motor. The assembly includes holes (54, 56, 58) in the 40 encoder disk. A seal (80) at an interface between the encoder housing and the encoder shaft to prevent contaminants from the cavity from entering the encoder housing and a packing inside the encoder housing. A packing (84) is situated to prevent any dust or debris associated with the encoder shaft rotating relative to the seal from getting on the encoder disk.

摘要： A rotatable coupling includes an input housing rotatably coupled to an output housing by a tube fixed to the output housing and on which tube the input housing rotates. The coupling includes two magnetic flux concentrators disposed about the tube and defining therebetween an annular cavity, a first concentrator fixed to the input housing and a second concentrator fixed to the output housing, such that relative rotation of the housings causes relative rotation of the concentrators on either side of the annular cavity. The coupling includes concentric coils disposed within the annular cavity that permit power transfer across the coupling, a first coil fixed to the input housing and a second coil fixed to the output housing; an emitter fixed to the input housing; and a receiver fixed to the output housing and positioned to receive the signals from the emitter during the relative rotation of the housings.
