5.3.1 Robot arm structure
An outline structure drawing is shown in
. Each part is as shown below.
1) The rotation of the J1 axis motor <1> arranged in the base is conveyed to the reduction gears <3> via the
timing belt <2> to rotate the J1 axis.
Brakes are not mounted in the J1 axis motor.
2) The rotation of the J2 axis motor <4> arranged in the No.1 arm is conveyed to the reduction gears <6> via
the timing belt <5> to rotate the J2 axis.
Brakes are not mounted in the J2 axis motor.
3) The rotation of the J3 axis motor <7> arranged in the No.2 arm is conveyed to the shaft via the timing belt
<8> to move the J3 axis as up and down.
Non-excitation magnetic brakes are mounted in the J3 axis motor.
4) The rotation of the J4 axis motor <9> arranged in the No.2 arm is conveyed to the shaft via the timing belt
(motor side) <10> and the timing belt (shaft side) <11> to rotate the J4 axis.
Brakes are not mounted in the J4 axis motor.
