A stiff, form-stable elongated tubular housing (1) is formed with an axially extending longitudinal slit (12). A drive spindle (4) is retained in bearings (8) located in end flanges (2) of the housing, driven for example by a motor (M). A pair of spindle nuts (5, 6) clamp, between themselves, a tubular portion (15) of a force transfer element (14) which is located externally of the housing and moved by a web (13) passing through the slit. The force transfer element is guided on the housing by interengaging groove and projection means (20, 21), which also isolate forces applied to the force transfer element from the spindle drive. The slit is closed off by a flexible web (23) which is lifted out of the slit in the region of the force transfer element by camming surfaces (33, 34) passed through a transverse opening (32) in the force transfer element, and re-seated in the slit by roller-and-pusher elements (35, 36, 37) which snap outwardly extending projections (30) of resilient web strips (28) behind the walls of the slit (12) to form a completely enclosed housing in which the spindle and spindle nuts are protected from environmental contamination, and which can retain lubricant for high-efficiency, low-noise force transmission and conversion. |
