An actuating apparatus has a first and a second actuating element that delimit a pressure chamber. The actuating apparatus has a rotary decoupling bearing coupled via a compensation assembly to the second actuating element for joint movement along the spatial axis. The compensation assembly comprises a first ramp element which is supported axially on the second actuating element and is preloaded relative to the second actuating element by a first preloading apparatus for rotation about the spatial axis and a second ramp element coupled to the rotary decoupling bearing. An axial overall length of the compensation group along the spatial axis changes in the case of a rotation, of the first ramp element relative to the second actuating element. The compensation assembly has a blocking element and a blocking toothing system in blocking engagement with a counter-blocking toothing system of the first ramp element

A synchronizer is provided for torsionally connecting a gear to an axially aligned shaft. The synchronizer includes a hub connected with the shaft, a sleeve having an inner diameter with spline teeth for torsional connection with the hub being axially movable upon the hub, a blocking ring torsionally connected on the hub having an angular lost motion relationship with the sleeve, the blocking ring having at least a first annular conical friction surface orientated radially inward and axially toward the hub and a second annular conical friction surface oriented radially inward and axially outward from the hub, the blocking ring having blocking cogs preventing axial movement of the sleeve toward the gear when the gear is in a non-synchronous condition, and an engagement ring for fixed connection with the gear, the engagement ring having a complementary annular conical friction surfaces.

Rotating a casing during a cementing operation to ensure efficient displacement of cement slurry. More specifically, embodiments are directed towards a sub and rotating tool that are positioned above a first cement operation, wherein the rotating tool is positioned in a kickoff point or build section of a horizontal well.

An axle disconnect assembly, including: a housing and a clutch a shaft with first splines; a sleeve including second splines non-rotatably connected to the first splines, and axially extending teeth; a shift lever including at least one pivot pin, a first end connected to the sleeve, and a second end; and an actuation assembly including an actuation shaft engaged with the second end of the shift lever, and an actuator. In a connect mode, the teeth are non-rotatably connected to a power output. In a disconnect mode, the sleeve is rotatable with respect to the power output. To shift from the disconnect mode to the connect mode: the actuator rotates the actuator shaft; the actuator shaft pivots the shift lever around an axis of the at least one pivot pin; and the first end of the shift lever displaces the sleeve, with respect to the shaft, in an axial direction.

The bearing provides an inner race, an outer race and a wear race that is made of synthetic material and fastened to one of the races. The wear race is overmolded on at least one face of the race. The face includes at least one retention means that is covered with the synthetic material of the wear race and shaped to allow both the axial retention and the angular retention of the wear race relative to the race by shape complementarity with the wear race.
