Abstract

A socket assembly for rotating a nut, the nut having an annular body with a radially inner edge defining a torque transferring surface, the socket assembly has: an intermediate socket extending axially relative to a central axis between a proximal end and a distal end, the proximal end of the intermediate socket engageable by a tool for rotating the intermediate socket about the central axis; and socket segments detachably connected to the intermediate socket in a circumferential array about the central axis, a socket segment of the socket segments having a nut-engaging end projecting radially outwardly relative to the distal end of the intermediate socket and engageable with the torque transferring surface of the nut to transfer a torque from the intermediate socket to the nut via the socket segments.

First claim

The invention claimed is:

1. A socket assembly for rotating a nut, the nut having an annular body with a radially inner edge defining a torque transferring surface, the socket assembly comprising:
an intermediate socket extending axially relative to a central axis between a proximal end and a distal end, the proximal end of the intermediate socket engageable by a tool for rotating the intermediate socket about the central axis; and
socket segments detachably connected to the intermediate socket in a circumferential array about the central axis, a socket segment of the socket segments having a web and a nut-engaging end secured to the web and projecting radially outwardly from the web, the nut-engaging end projecting radially outwardly relative to the distal end of the intermediate socket and engageable with the torque transferring surface of the nut to transfer a torque from the intermediate socket to the nut via the socket segments, the web of the socket segment disposed radially inwardly of the intermediate socket, the web extending from a web proximal end to a web distal end, the nut-engaging end located at or proximate the web distal end, the socket segment having a locking end at or proximate the web proximal end, the socket segments axially locked to the intermediate socket via the locking end.

2. The socket assembly of claim 1 , wherein the nut-engaging end defines at least one lug sized to engage a space defined between two adjacent teeth of the nut.

3. The socket assembly of claim 2 , wherein the nut-engaging end defines at least two lugs circumferentially distributed about the central axis, the at least two lugs protruding radially outwardly from the web of the socket segment.

4. The socket assembly of claim 1 , wherein the intermediate socket has a peripheral panel extending circumferentially about the central axis and an end panel secured to the peripheral panel and being transverse to the central axis.

5. The socket assembly of claim 4 , wherein the peripheral panel engages the socket segments, the peripheral panel located radially outwardly of webs of the socket segments.

6. The socket assembly of claim 5 , wherein the peripheral panel defines notches, the nut-engaging end received within a notch of the notches, the nut-engaging end protruding radially-outwardly out of the notch and beyond the peripheral panel to engage the nut.

7. The socket assembly of claim 4 , further comprising a retaining member removably secured to the end panel of the intermediate socket, the socket segments axially locked to the intermediate socket by the retaining member.

8. The socket assembly of claim 7 , wherein the locking end extends through a slot defined by the end panel of the intermediate socket, the locking end defining a groove, the retaining member defining tabs, a tab of the tabs engaged within the groove.

9. The socket assembly of claim 8 , wherein the tabs are non-equidistantly distributed about the central axis.

10. The socket assembly of claim 4 , further comprising a support ring, the web of the socket segment disposed radially between the support ring and the peripheral panel of the intermediate socket, the nut-engaging end of the socket segment supported radially by the peripheral panel and the support ring.
