Abstract

Claims (52)

1. A driven linear axis comprising:

a housing having a linear rail guide with two profile rails on which a carriage is arranged so as to be linearly movable back and forth with the aid of a transport device;

wherein the carriage has a guide body with two lateral track carriages and a multifunctional interface,

wherein the carriage is guided between the two profile rails with the aid of the two lateral track carriages,

wherein the transport device comprises a belt which circulates in the housing and is guided over two gears, at least one gear being configured as a drive gear,

wherein a drive device is set in the drive gear and configured in the form of a modular drive cartridge engaged in a torque-locking rotational connection with the drive gear,

wherein the drive device has an electric motor device and a gear device;

wherein a shaft arrangement with a hollow shaft as an output shaft is provided between the electric motor device and the gear device, said shaft arrangement being rotatably received on a bearing axis of the drive device, said bearing axis being torque-proof with respect to the housing,

wherein an input side of the gear device is connected to the hollow shaft in a torque-proof manner, and

wherein the drive gear is seated radially outwardly on an output side of the gear device and is coupled to the output side of the gear device in a torque-proof manner.

2. The driven linear axis according to claim 1 ,

wherein the multifunctional interface comprises a connection side comprising a mechanical interface and a media interface, and

wherein at least one reciprocable media drag device provides a media path to the media interface within the housing.

3. The driven linear axis according to claim 2 , wherein at least one drag chain of the reciprocable media drag device is arranged between upper and lower layers of the belt in the housing and rests on a plate-shaped device which is fixed laterally on an inside of the housing.

4. The driven linear axis according to claim 2 ,

wherein the media interface comprises a data signal interface, an electrical interface and a fluidic interface, and

wherein the at least one reciprocable media drag device provides a data signal path to the data signal interface, an electrical path to the electrical interface and a fluid path to the fluidic interface of the multifunctional interface.

5. The driven linear axis according to claim 4 ,

wherein the data signal interface, the electrical interface and the fluidic interface are provided radially inside the mechanical interface,

wherein the data signal interface is provided on a central axis of the mechanical interface, and

wherein the electrical interface and the fluidic interface are provided radially outside the data signal interface.

6. The driven linear axis according to claim 2 , wherein the connection side of the multifunctional interface is configured as a connection socket for a connection disk or as a connection disk for a connection socket.

7. An industrial robot having:

a robot arm, and

a robot base, the robot base comprising a housing having a linear rail guide with two profile rails on which a carriage is arranged so as to be linearly movable back and forth with the aid of a transport device;
