An apparatus, system and method for providing a floating end effector for grasping small precision parts. The end effector includes at least one end effector module having at least: tooling for grasping a part for pickup and placement; a module shaft connected on a first end to the tooling, and having a second end opposite the tooling; and at least two air bearing associated with the second end, wherein the at least two air bearings in combination impart degrees of freedom to the tooling in at least x and y axes and in theta.

The present disclosure relates to a frictional wave reducer mainly used for industrial robot joints and having an operating principle modified from that of a conventional strain wave gearing, which includes a wave generator having a conic pressurizing face on the outermost side, a toothless flex spline having a conic friction tube in which the wave generator is accommodated with the conic pressurizing face inscribed in the conic friction tube, and a toothless circular spline accommodating the toothless flex spline and having an internal conic friction face in which the conic friction tube is inscribed at a plurality of axially symmetrical points to form an internal friction wheel with the toothless flex spline. Accordingly, disadvantages of the conventional strain wave gearing are overcome to provide a reducer having high productivity and high rotation accuracy without generation of vibration and noise.

A joint bearing for a robot 1 which comprises a shaft 21 and at least one link element 24, 35, 36, 37, 38, 59, 60 mounted to be rotatable on shaft 21 between two axial bearings 22, 23, 43, 44, 45, 46, 54, 55, 63, 64, 69, where a resiliently compressible preloading element 33, 49, 52, 53, 56, 57, 65, 66 is provided which applies an axial preloading force to the axial bearings. A robot with at least one such joint bearing as well as a method for assembling a joint bearing for a robot are disclosed herein.

The present invention relates to a detection system for detecting wear of a ball-joint connection device of a pitch rod. The detection system includes at least one measurement assembly, said at least one measurement assembly having at least one deformation gauge for placing on said pitch rod, said detection system comprising at least one electrical conditioning circuit connected to at least one said deformation gauge and to at least one electrical energy source, said electrical conditioning circuit being configured to generate a measurement signal that varies as a function of deformation of said at least one deformation gauge and as a function of said wear.

A transmission, including an outer shell (1), an inner shell (2), a drive disk (3), a plurality of T-shaped teeth (4), a gear (5), a tooth seat (6), an adjustable nut (7), balls (8), inner balls (9), outer balls (10), an inner protective frame (11), an outer protective frame (12), rollers (13), a first sealing ring (14), a second sealing ring (15) and a third sealing ring (16). Transmission clearance can be adjusted freely at any time, the meshing of the T-shaped tooth and the gear is a real surface meshing, and almost all the teeth participate in force transmission simultaneously. Therefore, the transmission has high precision, high mechanical properties, and long service life.

A robot drive unit is provided with: a housing; a shaft body that is relatively rotated with respect to the housing; rotating-body sealing members that is provided in the housing; a contact-surface member that is provided on the shaft body and that contact with the rotating-body sealing members; and a sealing member that seals a gap between the shaft body and the contact-surface member.

A ring seal and a robot. The ring seal includes an outer circumferential wall and an annular portion. The outer circumferential wall extends in an axial direction of the ring seal. The annular portion extends from a side of the outer circumferential wall toward an interior of the outer circumferential wall in a radial direction of the ring seal. As viewed in a cross section taken along the radial direction, the annular portion and the outer circumferential wall form an L shape.

A telescopic shaft having a first shaft, a second shaft configured to enable a first relative movement in an axial direction between the first and second shafts, and a third shaft configured to enable a second relative movement in the axial direction between the second and third shafts, and a third relative movement in the axial direction between the first and third shafts. The second shaft is located between the first and third shafts. The telescopic shaft is configured to connect a base of a parallel kinematics robot to an end effector of the same for the purpose of transferring torque. By providing the telescopic shaft with more than two shafts with mutual relative movements between the same, an extension factor (the relation between the maximum and minimum lengths of the telescopic shaft) and by that the working area of the parallel kinematics robot can be increased.

A bearing assembly includes a bearing flange and a flange receptacle having a longitudinal axis, which comprise a mutual axial stop and a fixing for securing the mutual stop position. The fixing is designed as a wedge-type clamp which can be actuated transversely, in particular radially, to the longitudinal axis. The wedge-type clamp clamps the bearing flange and the flange receptacle axially into the mutual stop position. The bearing assembly may be, for example, provided for a robot and its rotary body.
