Abstract
A rod-less linear drive whose housing (2) delimits an interior space (4), in which a drive part (5) is located. The housing (2) is provided with a slot-like longitudinal opening (24), which on either side is flanked by a housing limb (25 and 26). An entraining part (35) connected with the drive part (5) projects through the longitudinal opening (24) to the outside, where it is kinematically coupled with a slide (36). The slide is supported by means of a guide means (41) on the housing (2), one of the two housing limbs (26) being extended through and past the longitudinal opening (24) and on the side, facing the other housing limb (26), bears the guide means (41).
Claims15
A piston rod-less linear drive comprising:
- a housing (2), which delimits a interior space (4) extending in the longitudinal direction (3), in which a drive part (5) is arranged for longitudinal movement and which has a slotted opening (24) directed into said housing interior space (4), said slotted opening being flanked in the longitudinal direction (3) on either side by a housing limb (25 and 26), which is constituted respectively by a portion of the housing (2),
- an entraining part (35) being arranged on the drive part (5), such entraining part extending outward through the slotted opening, and
- a slide (36) having a top surface forming a first load carrying surface and a slide limb positioned substantially perpendicular to said top surface, said slide limb extending downward past an extension section of the housing limb to form a second load carrying surface, said slide being kinematically coupled to said entraining part outside the housing (2), said slide being guided by a guide means (41) for movement in the longitudinal direction (3) in relation to the housing and being supported in the transverse direction (42), wherein one of the two housing limbs (26) is extended laterally past the longitudinal opening (24) forming an extension section (46) that bears the guide means (41) with the slide (36), and the other housing limb (26) is uncoupled from the slide as regards loads.
A piston rod-less linear drive comprising:
- a housing (2), which delimits a interior space (4) extending in the longitudinal direction (3), in which a drive part (5) is arranged for longitudinal movement and which has a slot-like opening (24) directed into said housing interior space (4), slot-like opening being flanked in the longitudinal direction (3) on either side by a housing limb (25 and 26), which is constituted respectively by a portion of the housing (2),
- an entraining part (35) being arranged on the drive part (5), such entraining part extending outward through the slot-like opening;
- and
- a slide (36) kinematically coupled to said entraining part outside the housing (2), said slide being guided by a guide means (41) for movement in the longitudinal direction (3) in relation to the housing and being supported in the transverse direction (42), wherein one of the two housing limbs (26) is extended laterally past the slot-like opening (24) forming an extension section (46), wherein said extension section (46) is integrally extruded with the guide means, and said extension section (46) bears the guide means (41) with the slide (36), and the other housing limb (26) is uncoupled from the slide as regards loads.
