Title:
BUILT-IN PLANETARY DRIVE
Document Type and Number:
WIPO Patent Application WO2005057047
Kind Code:
A8
Abstract:
Built-in planetary drive, joined as planetary gearings (1,3), aligned one behind the other, is solved into drum spaces, each of which is formed of one or two gear reductions (4,6,7). These are joined by the satellite carrier (21) or the ring gear (20) and joined to sun gear (30) of following planetary gearing. Sun gear (16) on driving shaft (9) is led by satellites (17,18,19), sun gear (30) is freely seated amoung double satellites (37,38,39). Together with led ring gear (34) of last gear reduction (7), differential mechanism (43,44,45) is formed for power distribution to individual satellites (17,18,19,37,38,39). Basic immobile supporting frame for the planetary drive is formed of hollow body (11) with built-in motor (14) and contracted section (12) and joining flange (13). To body (11), gear box (8) is joined frontally with overhung location of greater gears of satellites (37,38,39) of last planetary gearing (3) and with reached planetary gearing (1). Last gear reduction (7) is built into the space between outer circumference of contracted section (12) of body (11) and inside circumference of hub sleeve (48) which is driven by the ring gear (34) by coupling teeth (47).
