BALL GUIDE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: ball guide has C-shaped housing provided with a bore. C- shaped bushing having separator 3 of the same form is received in the bore. Circulating passage provided with ball 3 is made in separator 3. Gap 6 is provided between the housing and bushing 2. Bushing 2 is rigidly connected to the housing by screws 9 via projections 8 near opening 7. The axis of the bore is shifted inside the housing with respect to the axis of its outer surface to the direction of opening 7. Bushing 2 is thin-walled and has longitudinal projections 11 on its inner side. When the guide moves along the bearing shaft the load is transmitted to bushing 2 from housing 1. Balls 5, which are in contact with the longitudinal projections, move in the same direction and transmit the load to the bearing shaft. EFFECT: enhanced reliability. 2 cl, 2 dwg
