要約
(EN)

A thrust bearing for a hydro-static transmission according to the present invention is incorporated in a hydro-static transmission and includes: an inner ring which makes contact with pistons of piston chambers of a variable capacity pump; an outer ring fixed to a swash plate; a plurality of balls held between the inner ring and the outer ring via a retainer, where the retainer is made of a synthetic resin provided by polyamide 66, and contains glass fiver at a rate not greater than 10 mass percent. With this arrangement, the present invention prevents breakage of the retainer caused by delayed or speeded balls resulting from an imbalanced load when the pump swash plate varies its slant angle, thereby provides a long-life thrust bearing for a hydro-static transmission.
