Gear reduction unit

[0036] The following discussion relating to FIGS. 1-28 provides a detailed description of the unique gear reduction unit which can be utilized with the present invention. More torque capacity is the main advantage for using the right angle gears. For various torque capacities and design requirements different right angle gear sets could be used. Spiral bevel gears and hypoid gears are bevel type right angle gears. In pair of gears a pinion is a gear with less or equal number of gear teeth. Gears shown in schematic view could be bevel type (spiral bevel or hypoid) or face gear with regular worm or enveloping worm having threads with less than 90 degrees of revolution.

[0037]FIG. 1 is an isometric view of coaxially mounded first spiral bevel 1 and second spiral bevel gears 2 gears in mesh with coaxially mounded first pinion 3 and second pinion 4. Gears 1 and 2 are connected to each other. Output member 5 of gears 1 and 2 may be linked to a source of mechanical energy or to a load. Pinion
