Title:
SPROCKET SUPPORT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2011/108316
Kind Code:
A1
Abstract:
The disclosed sprocket support structure is compact, reduces friction loss accompanying sprocket rotation, and simplifies the process of machining a torque converter case. The sprocket support structure is provided with a bearing (40) for supporting the sprocket (30) so as to allow free rotation relative to the torque converter case (11), and an oil seal (39) which seals the gap between the torque converter case (11) and a sleeve (20). The bearing (40) is a ball bearing disposed in the radial gap between the inner surface (35a) of an opening (35) formed in the torque converter case (11) and the outer surface (31a) of the sprocket. Further, a first annular groove (36) for fitting the ball bearing (40) provided in the torque converter case (11) has a larger radius than that of a second annular groove (37) for fitting the oil seal (39). By this means, the machining direction of the second annular groove (37) can be identical to that of the first annular groove (36).
