Abstract
A linear drive, on which housing a longitudinally moving output drive part is provided. In the possible path of motion thereof a limiting device is arranged, with which the end or terminal position of the output drive part may be preset. The limiting device comprises at least one holder with an abutment-shock absorber unit. Along the housing a plurality of positioning points is provided, at which support element may be fixed in place, which render possible an interlocking or positive mounting of the holder. The abutment-shock absorber unit is able to be steplessly set in position in relation to the holder. It is in this manner that an exact and reliable adjustment of the path of travel of the output drive part may be undertaken.
Claims20
A linear drive comprising a housing which contains a drive part coupled kinetically with an output drive part which is movingly arranged outside the housing on a longitudinal guide extending in the longitudinal direction thereof, a device arranged outside the housing and cooperating with the output drive part for limiting the travel of the output drive part, which device comprises at least one holder adapted to be set in fixed relationship to the housing along a setting range in different longitudinal positions, and an abutment-shock absorber unit arranged on the holder and extending into the path of travel of the output drive part, wherein a plurality of spaced positioning points is provided along the range of setting, at which respectively at least one support element is or may be arranged in fixed relationship to the housing, the holder is adapted to be arranged and to be secured at each of these positioning points, which are provided with at least one support element, in at least one support setting corresponding to a given longitudinal position, in the support setting an engaging portion provided on the holder is hookingly engaged by the associated support element on the side facing away from the output drive part and is supported in the longitudinal direction, and furthermore the abutment-shock absorber unit is arranged on the holder for stepless adjustment in the direction of travel of the output drive part.
