Abstract: A gear motor includes a motor and a speed reducer and drives a joint portion of a cooperating robot which performs a work in collaboration with a person. In addition, in the gear motor, an operation ratio is 20% ED or less, a reduction ratio of the speed reducer is 30 or less, and an output rotating speed of the motor is 1000 rpm or less.

Abstract: A power transmission device having a motor which includes a stator around which a coil is wound, a motor frame which covers the stator, and a cover which covers an axial end portion of the motor frame. In addition, the cover is formed of a non-conductive material, and a shortest creeping distance between a coil end of the coil and the cover is shorter than 6.3 mm.

Abstract: A gear motor includes a speed reducer and a motor. The speed reducer includes an internal gear, an external gear, an input shaft having an oscillating portion oscillating the external gear, an oscillating bearing which is disposed between the external gear and the oscillating portion, and an input bearing which supports the input shaft, the input shaft includes a protrusion portion which protrudes from the motor side such that a rotor of the motor is provided in the protrusion portion, and includes a bearing disposition section in which the input bearing is disposed and a rotor disposition section in which the rotor is disposed in this order from the speed reducer side toward the motor side, an outer diameter of the rotor disposition section is equal to or less than an outer diameter of the bearing disposition section, and a rotor magnet is directly fixed to the rotor disposition section.

Abstract: A forming device that expands a metal pipe material to form a metal pipe includes a die that has an upper die and a lower die, at least one of which is movable, and that form the metal pipe, an electrode that energizes the metal pipe material to heat the metal pipe material, a gas supply part that supplies a gas into the heated metal pipe material to expand the metal pipe material, and a die movement suppressing part that suppresses the movement of the die by an electromagnetic force at least when the energization to the metal pipe material is performed by the electrode.

Abstract: A drive device configured to drive a container transporting device for transporting a container is provided. The drive device includes a motor which generates power, a brake configured to brake a movement generated by the power of the motor, and a speed reducer which has an output shaft connected to a driven portion of the container transporting device, includes a lubricant enclosed therein, and is configured to decelerate the power of the motor and transmit the decelerated power to the output shaft, in which the speed reducer, the brake, and the motor are disposed in this order from above in a vertical direction, a first seal member configured to block the lubricant is provided between the speed reducer and the brake, and the brake includes an accommodation chamber which accommodates a leaked lubricant in a case where the lubricant enclosed in the speed reducer leaks past the first seal member.

Abstract: Wheel drive apparatuses are provided on left and right wheels of a forklift and drive the respective wheels. Each of the wheel drive apparatuses includes a brake on the inside of a vehicle body of the forklift. The brake includes a brake shaft, friction plates, and a brake cover. The brake cover is removable from the wheel drive apparatus while the wheel drive apparatuses are mounted on the vehicle body. The friction plates are assembled with the brake shaft so as to be movable in an axial direction, and are removable from the wheel drive apparatus, while the wheel drive apparatuses are mounted on the vehicle body, by sliding along the brake shaft toward the inside of the vehicle body in the axial direction when the brake cover has been removed.
