An annulus spacer for a fuel channel assembly of a nuclear reactor is provided. The annulus spacer comprises a girdle wire forming a loop around a pressure tube of the reactor. The girdle wire has an expansion mechanism and defines a first circumference when the expansion mechanism is in a first configuration and a second circumference when the expansion mechanism is in a second configuration. The girdle wire transitions from the first configuration to the second configuration during diametral expansion of the pressure tube, where the expansion mechanism maintain a first end and a second end of the girdle wire in electrical communication in both the first and second configurations to maintain the loop of the girdle wire as a continuous electrical circuit. A garter spring defines the girdle wire within the garter spring and maintain a gap between the calandria tube and the pressure tube.

The present invention discloses a rotating shaft sealing device installed between a blower comprising a drive shaft rotated by a drive motor, an impeller connected to the drive shaft by an axial coupling and rotating, and a casing housing the impeller, the device comprising: a sleeve fixed to the outer surface of the drive shaft via a packing; a seal housing covering the outer surface of the sleeve and having a plurality of sealing grooves arranged along the longitudinal direction of the drive shaft on its inner surface; a plurality of seals arranged along the longitudinal direction of the drive shaft and an annular garter spring inserted into a spring groove on the outer surface of the seal to support the annular spacing between the segments of the seals and the plurality of seals arranged along the longitudinal direction of the drive shaft, the seal housing being divided into several segments to expand radially between the sleeve and the seal housing.

A sealing device may include the tone wheel and a lip seal which are coupled together. The sealing device may also include an over-mold chamfer coupled to the tone wheel. The tone wheel may include a wheel outer axial portion defining axial slots. An axle assembly may include a sensor which sense the axial slots. The lip seal may include an outer ring, a carrier coupled to the tone wheel, a garter spring, a spring gasket coupled to the garter spring and sealing the outer ring and the carrier, a carrier gasket sealing the outer ring and the carrier, and an insert.

Systems, methods, and apparatus for implementing a sealing device having a garter spring assembly in a well system. The sealing device may include a sealing element configured to establish a seal in a wellbore of the well system. The sealing device may also include a garter spring assembly coupled with the sealing element. The garter spring assembly may include one or more garter springs and a premade continuous insert positioned within a cavity formed by an inner diameter of the one or more garter springs and configured to fill the cavity. The garter spring assembly may include adjacent garter springs that are positioned to have opposite coil orientations.

A ball joint assembly includes a ball joint having a ball stud with a shaft portion and a ball head portion, the ball head portion being rotatably retained within a housing. The ball joint assembly further includes a dust cover adapted to cover the ball joint. The dust cover includes an upper-end portion and a lower-end portion. The upper-end portion is fixed to the housing and the lower-end portion is fixed to the shaft portion. Further, the dust cover is securely attached to the ball joint using at least one garter spring. The at least one garter spring is adapted to be arranged at the upper-end portion or at the lower-end portion and is configured to fasten the dust cover to the housing or to the shaft portion.
