Abstract

내하중 능력을 높이고 프레스 하중 방향의 이동량을 최소화하는데 목적을 두고, 내경중심(Ob)(축선 ZII)가 편심부(2)의 축선(Z1)에 대하여 소정량(e2)만 편심장착된 미끄럼축(31)과 내경중심(Oj)(축선 Z12)가 편심부(2)의 축선(Z1)에 일치되어 그 양측에 장착된 한쌍의 구르는 베어링(41,41)으로 구성되어 미끄럼 베어링(31)의 최소극간(h0)의 위치를 프레스 하중 방향으로 최대유막압력을 발생할 수 있는 위치로 결정함과 아울러 최소극간의 값(h0)을 구르는 베어링(41)의 잔류래디알 방향 크리어런스 δc와 전동체(43)의 정정격 하중(W)에 기인한 변형량 δr과의 합계한(δc+δr) 이하로 형성하였다.For the purpose of increasing the load carrying capacity and minimizing the amount of movement in the press load direction, the inner shaft center (Ob) (axis ZII) is a sliding shaft in which only a predetermined amount (e2) is eccentrically mounted with respect to the axis (Z1) of the eccentric portion (2). (31) and the inner diameter center (Oj) (axis Z12) coincide with the axis Z1 of the eccentric portion 2 and consist of a pair of rolling bearings 41 and 41 mounted on both sides thereof, so that the sliding bearing 31 is The position of the minimum gap h0 is determined as the position where the maximum oil film pressure can be generated in the press load direction, and the residual radial direction clearance δc of the bearing 41 rolling the value h0 between the minimum poles and the rolling element ( It was formed below the sum total (delta c + delta r) with the deformation amount (delta) r resulting from the static load load (W) of 43).
