Description

Multiple Interface Gearlng This invention relates to the transmission of power by gears.
In existing designs transfer limitations depend upon gear material, dimensions and angles.
In this invention more than one gear interface is used thus reducing the contact area required by each.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 Shows a schematic plan of two pinions (b and c) driving a single crown wheel (a) from a single input (d).
Figure 2 Shows a perspective view of the same.
In this example torque is transmitted to both sides of the crown wheel using a main shaft and a lay shaft. This same configuration may be used to drive the two pinions from single crown wheel. In this gear format the shaft layout may also be used as the basis of a lubricant pump.
Other possible forms of the same invention might include: the use of contrait, worm, bevel, hyploid or any other type of gear.
variation in angles or sizes, or the use of intemal angles instead of extemal angles or visa versa the use of different numbers or forms of any component, features or amalgamation of any of the components or features or any other materially similar configuration.

Claims (28)

1. An assembly or configuration of gears with or without teeth wherein one or more interfaces are used to split and or combine paths of power transmission.
2. An assembly or configuration of gears as claimed in claim 1 where the arrangement is such that more than one interface exists on one or more gears.
3. An assembly or configuration of gears according to claim 1 or 2 where the arrangement is such that at least one gear has one set of two or more interfaces that ultimately drive a common single output (i.e. in parallel).
4. An assembly or configuration of gears according to claim 1 or 2 where the arrangement is such that at least one gear has at least one set of two or more interfaces that ultimately drive a common single output (i.e. in parallel).
5. An assembly or configuration of gears as claimed in any ofthe preceding claims wherein the said gear or gears drives at least one other output.
6. An assembly or configuration of gears as claimed in any of the preceding claims where the said gear or gears are driven by at least one input.
7. An assembly or configuration of gears as claimed in any of the preceding claims where at least one gear has at least one set of two or more interfaces ultimately driven by the same input.
s. An assembly or configuration ofgears as claimed in any of the preceding claims where any second or further output interfaces are ultimately and or ultimately and only further connected to the same output as the first.
9. An assembly or configuration of gears as claimed in any of the preceding claims where any second or further input interfaces are ultimately and or ultimately and only further connected to the same input as the first.
1O.An assembly or configuration ofgears as claimed in any ofthe preceding claims where the arrangement is such that more than one interface exists between at least one pair of directly connected gears (e.g. two sets of teeth).
11 .An assembly or configuration of gears as claimed in any preceding claim where at least one set of teeth on any particular gear interfaces with two or more other gears.
12.An assembly or configuration of gears as claimed in any preceding claim where at least one gear has at least one set of teeth which interfaces with two or more other gears ultimately being driven by a common input.
13.An assembly or configuration ofgears as claimed in any preceding claim where at least one gear has at least one set of teeth which interfaces with two or more other gears ultimately driving a common output.
14.A gear configuration as claimed in any preceding claim wherein at least one gear has two or more sets of teeth which ultimately drive a common output.
15.A gear configuration as claimed in any preceding claim wherein at least one gear has two or more sets of teeth which are ultimately driven by a common output.
16.A gear configuration according to any preceding claim where the path of power transmission is split and recombined at least once through the use of more than one gear interface on any single gear or gears such that the power is transmitted in parallel.
17.A gear configuration where the path of power transmission is combined and re-split through the use of more than one interface on either side of the gear wheel.
18.A gear configuration as claimed in any preceding claim wherein two or more of the interfaces are on one or more sets of teeth on the same face of a gear.
19.A gear configuration as claimed in any preceding claim wherein two or more ofthe interfaces are on two or more sets of teeth on opposite faces of a gear.
20.A gear configuration as claimed in any preceding claim wherein two of the interfaces are on two sets of teeth on opposite faces of a gear.
21.A gear configuration as claimed in any preceding claim wherein two ofthe interfaces are on two identical sets of teeth on opposite faces of a gear.
22.A gear configuration as claimed in any preceding claim wherein the direction or sequence of power transmission is variable or varies.
23.As claimed in claims 1 to 18 wherein the purpose of having number of interfaces is to balance the separation forces or to reduce the power transmitted through any one interface.
24.As claimed in claim 19 wherein the smaller power transfer requirement allows smaller tooth sizes and thereby allowing smaller gear wheel sizes for a given speed ratio at a given torque.
25.A gear configuration substantially as described herein with reference to figures 1-2 of the accompanying drawing.
26.As claimed in claim 22 wherein the particular gear configuration is also used as the basis of a lubrication pump.
27.A gear configuration as claimed in preceding claims wherein angles are varied.
28.As claimed in any combination ofthe previous claims.
