発明の名称
(EN) Thrust bearing for hydraulic continuously variable transmission
(ZH) 液压式无级变速器用的推力轴承
要約
(EN) This thrust bearing for a hydraulic continuously variable transmission is a thrust bearing incorporated in a hydraulic continuously variable transmission (30) and is provided with: an inner race (12)that contacts pistons (35) in a piston chamber (34) of a variable capacity pump (32); an outer race (14) fixed to a swash plate (37); and multiple balls (15) held between the inner race (12) and the outer race (14) by a cage (16). The cage (16) is formed from a synthetic resin obtained from polyamide 66 and the content of glass fibers contained is 10 mass% or less. The present invention thereby prevents damage of the cage (16) due to delay or advance of the balls (15) when an eccentric load is applied according to the angle of inclination of the pump swash plate (37), and is able to increase service life.
(ZH) 本发明提供一种液压式无级变速器用的推力轴承,其组装于液压式无级变速器(30),包括:与可变容量泵(32)的活塞室(34)的活塞(35)接触的内圈(12);固定于斜板(37)的外圈(14);和在内圈(12)与外圈(14)之间由保持器(16)所保持的多个滚珠(15),保持器(16)由包括聚酰胺66的合成树脂形成,且含有的玻璃纤维的含量的比例在10质量%以下。由此,本发明中,即使根据泵斜板(37)的倾斜角度而施加偏载,也能够防止由于滚珠(15)的滞后运动或提前运动而造成的保持器(16)的损坏,延长寿命。
