A retainer device for assembly with an associated shaft by an associated expansion device is disclosed which includes a ring body having a first arcuate leg, a second arcuate leg, a first lug is disposed at one end of the first arcuate leg and a second lug is disposed at one end of the second arcuate leg. The enhanced lugs are adapted to receive the associated expansion device when oriented both axially and radially with respect to the associated shaft.

Aspects of novel connection systems and methods are disclosed herein. A partially hollow nose is configured to one of connect a pathway to a body catch to accept a quick connect body (QCB) or mate with a connection system configured to be inserted into a shaped cavity in the nose; and, a quick connect module (QCM) and the nose are configured to cooperate to accept insertion of the QCB through the side wall of the nose into the body catch of the QCM; wherein the QCB affixes the QCM into the nose; and, wherein pushing on the button at one end of the QCB compresses the integral biasing arm of said QCB opening a catch and release interface to accept a tool.

A lock ring that has a first ring half, a second ring half and a latch assembly. The first ring half includes a nest opening on a front portion of the first ring half, a back end portion of the first ring portion hingedly connected to a back end portion of the second ring half. The latch assembly is connected to a front portion of the second ring half. The latch assembly includes a connection arrangement and a spring system. The connection arrangement is designed to be releasably positionable in the nest opening. The spring system is designed to cause the front portions of the first and second ring halves to be drawn toward one another when the connection arrangement is positioned in the nest opening.

Connector (1) comprising at least one female part (2) and at least one male part (3) engaging in the female part, and locking means (4) preventing any extraction of the male part from the female part, characterized in that the locking means comprise at least one removable locking part (4) arranged as an interface between the male part (3) and the female part (2), and the male and female parts comprise means of retention (24, 35) by mutual cooperation, the mutual disengaging of the retention means being rendered possible only after the withdrawal of the locking part.

An actuator of a refrigerant valve is described, the actuator comprising a housing (5) having a chamber (12) with an opening (15) in an end face (26) of an end section (17) of the housing (5), the end section (17) having an outer thread (18), a tightening collar (6) having a radially inwardly protruding flange (20) and an inner thread (19) matching the outer thread (18), and an anchor ring (7) positionable between the tightening collar (6) and the end face (16), wherein the anchor ring (7) is elastically deformable at least in a radial direction with respect to an axis of the outer thread (18) and in a mounted condition at least partially overlaps the end face (16) and the flange (20) of the tightening collar (6), wherein a sealing ring (8) at the end face (16) shows a free side to the axial direction and is com-pressed by an axial force produced by screwing the tightening collar (6) onto the outer thread (18).

A push-on fastener including: a conductive, annular push-on fastener body including a major surface and a radial edge defining a peripheral surface, the push-on fastener body forming an aperture defining a central axis; and a non-conductive sliding layer overlying the major surface of the push-on fastener body, where the major surface includes a void area free of non-conductive sliding layer adapted to contact an inner component or an outer component so as to provide electrical conductivity between the push-on fastener and a neighboring component.

The invention relates to a blade pivot with adjustable orientation for a turbomachine fan hub, comprising a stud having means for retaining a fan blade root and coupling means for the transmission of a torsional torque, a rolling bearing for absorbing the centrifugal forces having an inner bushing mounted in transverse abutment against an external radial portion of the stud, a ring for radially retaining the stud relative to the rolling bearing housed in an annular groove formed in the stud, a plurality of clamping parts each mounted in transverse abutment against the retaining ring and in radial abutment against the inner bushing of the rolling bearing, and a clamping nut screwed onto an outer thread of the stud to come into conical abutment against the clamping parts such that said clamping parts ensure a clamping of the inner bushing of the rolling bearing on the stud and a clamping

A ratchet fitting includes a screw portion and an operating portion. One of the screw portion and the operating portion has an engaging member, and the other one of the screw portion and the operating portion has an elastic member and a holding member formed separately from the elastic member. The elastic member and the engaging member are fitted such that a rotational force is transmittable to each other due to engagement of the projection and the protrusion and engagement between the projection and the protrusion is releasable due to deformation of the elastic member. The elastic member has a first fitting portion, the holding member has a second fitting portion, and the holding member and the elastic member are fitted such that the first fitting portion and the second fitting portion are fitted to each other in a rotation direction.

A motor case assembly includes a shaft and a motor case. The shaft has a connection end formed with a groove. The motor case has a perforation for assembling and connecting with the shaft. A hub section protrudes a rim of the perforation and has a forced outer face and an inner face surrounding the connection end and the groove of the shaft. An external means is used to apply an external force to the hub section so as to make the hub section tightly hoop the connection end of the shaft. By means of the external force, the inner face of the hub section is partially intruded into the groove of the shaft to form an intrusion body connected with the groove under a top wall inner face of the motor case. Therefore, the motor case and the shaft are securely connected with each other without easy detachment.
