A driving apparatus has a problem in that foreign matter, such as grease, in a reduction gear moves from the reduction gear to a coupling side. Therefore, a driving apparatus includes an input shaft with a hollow space, a motor that rotates the input shaft, a reduction gear that receives the power of the motor from the input shaft, an output shaft inserted through the hollow space of the input shaft and adapted to rotate about the rotation axis of the motor, and a coupling connected to a tip end of the output shaft. A first limiting member for limiting the movement of foreign matter in the reduction gear toward the coupling side is arranged between the reduction gear and the coupling.

Driving apparatus

A driving apparatus has a problem in that a tip end of an output shaft, which is inserted through a hollow space, is difficult to be fitted into the apparatus body during the maintenance. Therefore, a driving apparatus includes an input shaft with a hollow space formed therein that penetrates therethrough in the axial direction, a motor that rotates the input shaft, a reduction gear that receives the power of the motor from the input shaft, an output shaft inserted through the hollow space of the input shaft and adapted to rotate about the rotation axis with power output from the reduction gear, and a coupling connected to a tip end of the output shaft. A first bearing for supporting the output shaft is arranged, and a second bearing for supporting the output shaft is arranged in the hollow space between the input shaft and the output shaft.

A driving apparatus has a problem in that during the maintenance operation, foreign matter moves from the tip end side of an input shaft into a hollow space. Therefore, a driving apparatus includes an input shaft with a hollow space formed therein, the hollow space penetrating therethrough in the axial direction, a motor that rotates the input shaft, a reduction gear that receives the power of the motorfrom the input shaft, an output shaft inserted through the hollow space of the input shaft and adapted to rotate about the rotation axis with power output from the reduction gear, and a detector that detects information on the rotation of the input shaft and the output shaft. A limiting member, which limits the movement of foreign matter into the hollow space of the input shaft from one side to the other side of the motor, is arranged in the hollow space between the input shaft and the output shaft.

The present invention is characterized by arranging a flow pathfor supplying driving gas to a tool mounting portionfrom a robot baseto the tool mounting portionthrough the interiors of a rotation frame, a tube, a shoulder, a swing armand a tool mounting rotation arm

Industrial robot

A light emitteris so mounted to a mounting portionprovided at a predetermined position of the tool mounting rotation armthat a light beam LB is emitted toward a swing arm, the light beam LB is caused to be emitted from the light emitter, and the swing armand the tool mounting rotation armare so positioned that the light beam LB from the light emitteris irradiated to an allowable range of a light receiving portionfor receiving the light beam LB from the light emitter

The present invention relates to an industrial robot and aims to provide an industrial robot capable of ensuring a long distance from a rotation axis of an arm to a tool mounting portion and accurately positioning the tool mounting portion by a compact structure. In a swing armthe rotation of a tool mounting rotation arm driving motoris transmitted to a pivot shaftvia a tool mounting rotation arm driving transmission mechanismthe rotation of a tool mounting portion driving motoris transmitted to an intermediate power transmission shaftvia a tool mounting portion driving first transmission mechanismand the rotation of the intermediate power transmission shaftis transmitted to an output power transmission shaftvia a tool mounting portion driving second transmission mechanismthereby rotating a tool mounting portionwhile being decelerated by a tool mounting portion driving reduction unit

A cable arrangement for a robot arm is provided, which includes a rotation arm and a line member such as a power cable. The rotation arm has a front end and a base end, the front end being provided with a swing shaft, the base end being provided with a rotational shaft rotatable about a longitudinal axis. The line member extends from the base end toward the front end of the arm. The rotational shaft includes a line offset member formed with at least one through-hole for passing the line member. The through-hole as a whole is offset from the axis of the rotational shaft.
