Abstract
In a spindle gear mechanism (1) having a spindle component (2) with a spindle thread (21) which has a pitch which alters over a longitudinal axis of the spindle component (2), and having a threaded component (3) which engages in the spindle thread (21), wherein the two components (2; 3) can be displaced relative to one another in relation to the longitudinal axis (1) of the spindle component (2), provision is made, for the purpose of straightforward production capability and suitability for a large number of applications, for the threaded component (3) to have at least one freely movable threaded element (4) which engages in the spindle thread (21) and, during operation, adapts automatically to the pitch of the spindle thread (21).
Claims21
A spindle gear (1) having a spindle component (2) with a spindle thread (21) having a pitch which varies over a thread element (1) of the spindle component (2) and a thread component (3) which engages into the spindle thread (3), wherein the two components (2, 3) are displaceable relative to each other with respect to the longitudinal axis (l) of the spindle component (2), the thread component (31) has at least one freely moveable thread element (4) which engages into the spindle thread (21) and in operation automatically adapts to the thread pitch of the spindle thread (21).
