Abstract
Abstract A flexible, cantilevered, gear wheel support, comprising a flexible pin mounted at one end in a rotating carrier and carrying at the other end a gear wheel the axis of which, when the pin flexes, remains parallel to the position of this axis in the pin unflexed condition; the pin between its mounting on the carrier and its part that carries the gear wheel presenting a greater resistance to bending in planes radial of the rotational path of the carrier than it presents to bending in planes tangential to this path.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
A flexible, cantilevered, gear wheel support, comprising a flexible pin mounted at one end in a carrier which is rotational in operation, and carrying at the other end a gear wheel such that the axis of the gear wheel, when the pin flexes under operational loads, remains parallel to the position of this axis in the pin unflexed condition; the pin between its mounting on the carrier and its part that carries the gear wheel being so shaped as to present a greater resistance to bending in planes radial of the rotational path of the carrier than that presented to bending in planes tangential to this path.
Claim 2
Dependent Claim
107 words
A flexible, cantilevered, gear wheel support, comprising a flexible pin mounted at one end in a carrier which is rotational in operation, and carrying at the other end a gear wheel such that the axis of the gear wheel, when the pin flexes under operational loads, remains parallel to the position of this axis in the pin unflexed condition; the pin between its mounting on the carrier and its part that carries the gear wheel being so shaped as to present a greater resistance to bending in planes radial of the rotational path of the carrier than that presented to bending in planes tangential to this path.
Claim 3
Dependent Claim
48 words
A gear wheel support according to claim 1, wherein the pin between its mounting on the carrier and its part that carries the gear wheel is substantially part circular with opposed flat surfaces that are substantially parallel to a plane radial of the rotational path of the carrier.
Claim 4
Dependent Claim
13 words
A gear wheel support according to claim 1, wherein the pin is hollow.
Claim 5
Dependent Claim
19 words
A gear train having gear wheels mounted on gear wheel supports, each support being as claimed in claim 1.
