Abstract
Abstract A ring gear component driven by a bevel gear wherein the ring gear component has a tension brace or support means on the bevel gear side to resist deflection of the ring gear away from the bevel gear under conditions of impact loading or heavy stress. The improved ring gear component is particularly adapjed for utilization in differential gearing utilized, for example, in the automotive field.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
148 words
A beVel ring gear component comprising: an elongate generally circular hub, web means surrounding and extending radially out from said hub in a plane transverse to and spaced a distance from one end of the hub, a bevel ring gear disposed circumferentially about and rigid on said web means and having a circular row of bevel gear teeth coaxial with and facing said one end of said web, and bracing means extending between and rigidly joined to said web means closely adjacent said ring gear and to said one hub end in a manner such that said bracing means extends between said web means and hub at an oblique angle to the hub and acts in tension to resist deflection of said web means in the direction of the opposite end of said hub under the thrust in said direction of a gear mating with said ring gear.
Claim 2
Dependent Claim
148 words
A beVel ring gear component comprising: an elongate generally circular hub, web means surrounding and extending radially out from said hub in a plane transverse to and spaced a distance from one end of the hub, a bevel ring gear disposed circumferentially about and rigid on said web means and having a circular row of bevel gear teeth coaxial with and facing said one end of said web, and bracing means extending between and rigidly joined to said web means closely adjacent said ring gear and to said one hub end in a manner such that said bracing means extends between said web means and hub at an oblique angle to the hub and acts in tension to resist deflection of said web means in the direction of the opposite end of said hub under the thrust in said direction of a gear mating with said ring gear.
Claim 3
Dependent Claim
54 words
A bevel ring gear component according to claim 1 wherein: said bracing means comprises a hollow shell-like bracing cone coaxially surrounding said hub with the large cone end adjacent and joined to said web means close to said ring gear and the small cone end joined to said hub adjacent said one hub end.
