Robot
A robot including: a driving mechanism that drives a movable member with respect to a base; and a fan that cools the driving mechanism, wherein the driving mechanism is provided with a motor, and a reducer that is disposed between the base and the movable member and that moves the movable member with respect to the base by reducing the speed of the rotation of the motor, the motor and the reducer are disposed on either side of a securing plate that is secured to the base, the cooling fan is disposed on an opposite side from the securing plate with the motor interposed between the fan and the securing plate, a space in which a surface of the reducer is exposed is formed outside the reducer, and the securing plate is provided with a vent that is connected to the space by passing through the securing plate.
1. A robot comprising:
a driving mechanism that drives a movable member with respect to a base; and
a cooling fan that cools the driving mechanism,
wherein the driving mechanism is provided with a motor and a reducer that is disposed between the base and the movable member and that moves the movable member with respect to the base by reducing the speed of the rotation of the motor,
the motor and the reducer are disposed on opposite sides of a securing plate that is secured to the base,
the cooling fan is disposed on an opposite side from the securing plate, with the motor interposed between the cooling fan and the securing plate, and generates an airflow that is circulated along a surface of the motor,
a mounting base secured to the base is provided with an accommodating space formed as a hole in the base with a circular lateral cross section, one end of the accommodating space is closed off by the securing plate, the reducer is disposed inside the accommodating space, and a space in which a surface of the reducer is exposed is formed between an outer circumferential surface of the reducer and an inner circumferential surface of the accommodating space, and
the securing plate is provided with a vent that is connected to the space by passing through the securing plate in a thickness direction thereof, and through which the airflow generated by the cooling fan passes into the accommodating space,
wherein an airflow-guiding portion is formed by strip-shaped plate members and is disposed so as to surround the motor and the vent at positions that are radially further outside than the vent, and blocks the airflow that is circulated along the surface of the motor and guides the airflow to the vent and into the accommodating space.
2. The robot according to claim 1 , wherein the vent comprises a plurality of vents, and the plurality of vents are provided around the motor with an interval therebetween in a circumferential direction.
3. The robot according to claim 1 , wherein the airflow-guiding portion is provided around the entire circumference around the motor.
4. The robot according to claim 1 , wherein the airflow-guiding portion is integrally formed with the securing plate.
