Abstract
In order to produce a window-actuator drive having assembly and service friendliness, particularly by providing a design which enables the gearbox unit to be easily exchanged, the drive is designed as two functionally separate units. A gear housing, a worm gear, and a housing cover which is sealed off from them both makes up a first unit. A cable housing with a cable pulley makes up a second unit. The subassemblies of the first and second unit can be assembled by means of notched, snap-fit connections.
Claims20
In a control drive, having an electric motor and two separate units assembled together including a first unit secured to a side of the motor with comprises:
- a first cup-shaped gear housing, an axle mounted in said cup-shaped housing and protruding axially out of said first unit, and a driving disk rotatably supported on said axle and driven by said motor, said driving disk including a protruding slaving member extending substantially parallel to said axle;
- and a second unit positioned on an ouput driven side of the control device and having a second housing, a driven disk having an extending member, said driven disk rotatably supported by said second housing through said extending member, such that, when the units are mutually assembled, said driven disk is supported on said axle protruding axially out of the first unit, the improvement comprising:
- said first unit being separable and distinct from said second unit, a housing cover secured to the first cup-shaped housing for sealing and securing in position the driving disk;
- a first seal positioned between sad housing cover and said driving disk for sealing said cover from the protruding slaving member of the driving disk;
- and the second housing of said second unit being cup-shaped and disposed opposite said first housing, said driven disk supported for rotation through said extending member by said second housing so that said first and second units can be separated without disassembling either of said units, said driven disk being supported for rotation of said axle and by said second housing when said first and second units are assembled.
A control drive comprising:
- a. an electric motor;
- b. a first unit secured to a side of the motor which comprises:
- a first cup-shaped gear housing, an axle mounted in said cup-shaped housing and protruding axially out of said first unit, a driving disk rotatable supported on said axle and driven by said motor, said driving disk including a protruding slaving member extending substantially parallel to said axle, a housing cover secured to the first cup-shaped housing for sealing and securing in position the driving disk;
- a first seal positioned between said housing cover and said driving disk for sealing said cover from the protruding slaving member of the driving disk;
- and
- c. a second unit positioned on an output driven side of the control drive and being separated and distinct from the first unit which comprises:
- a second cup-shaped housing, a driven disk having an axially extending member, said driven disk rotatably supported by said second housing through said extending member, such that, when the separate and distinct first and second units are mutually assembled to form said control drive, said second housing is disposed opposite said first housing, and said driven disk of said second unit is supported for rotation on said axle protruding axially out of the first unit and by said second housing.
