Abstract
PURPOSE: To secure both an extremely smooth linear movement and a rotation movement, simultaneously and also to obtain a large load capacity by a method wherein a shaft having a spiral groove and a guide ring having a circular groove are engaged with each other through two or more balls.
CONSTITUTION: Two or more rows of spiral groove 2 are installed at a shaft 1 and it is engaged with a guide ring 5 having circular grooves 4, 6 on the inner and outer peripheries by means of each each ball 3 placed in the spiral groove 2. To obtain the required roller bearing, an outer side guide 8 having a circular groove 9 in the inner periphery is meshed with the outer side of this guid ring 5 by means of steel balls 7. With this bearing, when the shaft 1 is going to move to an arrow head A direction, since the ball 3 is in contact with the spiral groove 2 at the point P1 and it is also in contact with a circular groove 4 at the point P2, the ball 3 rotates to an arrow head B direction, accordingly, the guide ring 5 rotates to an arrow head C direction. At this time, the contact at each part is entirely a roller contact, therefore, its movement is very smooth.
