Abstract
The invention concerns an electromechanical drive for a door or the like, with a motor and a transmission, which are connected with each other, wherein a drive gear in the form of a gear wheel or the like is present on a drive shaft of the transmission and cooperates with means for moving the door or the like, preferably in or on a guide rail. The drive has a modular design, and it has a compact power unit that can be used with different types of mounting units for different doors. In this regard, the power unit is equipped with a standard mounting bracket. In addition, different housings can be used for different areas of application.
Claims16
An electromechanical drive for a door, the drive comprising:
- a mounting unit mounted on a door, the mounting unit comprising a single stamped sheet of metal having a base plate and a pair of lateral sections, the lateral sections supporting a shaft, and a means for moving the door on the shaft;
- a mounting bracket being interchangeably fixed to the mounting unit;
- a motor supported on the mounting bracket;
- a transmission connected to said motor and having an output shaft, said transmission being directly supported by and frictionally connected to the mounting bracket;
- and
- a drive gear fixed to the output shaft and cooperating with the means for moving the door;
- wherein the means for moving the door comprises a driving pinion for cooperating with a toothed section of a running rail to move the door;
- wherein the single stamped sheet of metal of the mounting unit further comprises at least one mounting flange extending from the lateral sections;
- wherein the mounting bracket comprises at least one base shank;
- and
- wherein at least one of the mounting flange and the base shank has a recess extending in from an edge and the other of the mounting flange and the base shank has a mounting fixture being held in a recess on the mounting unit for interchangeably fixing the mounting bracket to the mounting unit.
