초록 ▼

Disclosed herein is a multi-mesh gear system, such as an epicyclic gear system, in which (a) optimal performance is not load-specific and (b) the same profile modifications can be applied on both flanks of the common gear. This is accomplished through a novel combination of a constant system contact

Disclosed herein is a multi-mesh gear system, such as an epicyclic gear system, in which (a) optimal performance is not load-specific and (b) the same profile modifications can be applied on both flanks of the common gear. This is accomplished through a novel combination of a constant system contact ratio and gearing having mesh stiffness variation reducing, or MSVR, modifications. An MSVR modification, such as Differential Crowning, will minimize the self-excited component of dynamic load for gear meshes across different operating loads, resulting in an optimized gearset. The specification of a substantially constant contact ratio for the multi-mesh gear system allows the same MSVR modification to be used on both tooth flanks of the common gear, reducing the cost and complexity of manufacture.

The cable guide sleeve for an electric cable emerging from a tube according to claim 1 wherein a reverse side of the deflector comprises a rear projecting reinforcement. 9. The cable guide sleeve for an electric cable emerging from a tube according to claim 1 wherein the cable guide sleeve and the deflector are made of a synthetic material. 10. The cable guide sleeve for an electric cable emerging from a tube according to claim 1 in combination with a tube for an axially movable guided piston for a drive of a seat belt tightener, and an electric cable that is an ignition cable for igniting an electrically ignitable propellant for driving a piston along a guide path inside the tube, whereby the ignition cable extends along the guide path inside the tube and is guided out of the inside of the tube through the lateral opening of the casing of the tube by the deflector arranged inside the tube. 11. The cable guide sleeve for an electric cable emerging from a tube according to claim 10 wherein the lateral opening in the casing of the tube is arranged in a part of the tube situated outside the axial guide path of the driven piston. 12. The cable guide sleeve for an electric cable emerging from a tube according to claim 10 wherein the end of the guide path is determined by an end stop, in particular in the shape of at least one indentation in the tube wall. w formation disposed in axial alignment with the longitudinal central axis of said transverse pin for receiving in friction fit a portion of said transverse pin of a mating half-pipe section and on opposed sides of said clamping ball end whereby to interconnect and align two of said half-pipe sections together. 2. An underwater cable protection pipe as claimed in claim 1 wherein said stub end is formed with an enlarged curved side wall end section to form a small ball end when two of said half-pipe sections are interconnected in juxtaposition, said small ball end having an outer diametrical surface which is dimensioned to fit within the inner diametrical surface of said clamping ball end to permit articulation of two interconnected pipes. 3. An underwater cable protection pipe as claimed in claim 1 wherein said half-pipe sections are cast of anodized aluminum having a weight which is substantially half of ductile iron. 4. An underwater cable protection pipe as claimed in claim 1 wherein there is further provided a pair of flanges formed behind said clamping ball end and projecting outwardly of an outer side wall of said half-pipe sections, a transverse hole formed in said flanges, said half-pipe sections when matingly interconnected together causing said flange holes to align, said aligned holes providing for a fastener to interlock a last one of a series of said protection pipes interconnected end-to-end thereby interlocking all of said pipes while permitting articulation of said pipes.
