5.3.1 Robot arm structure

An outline structure drawing is shown in
shown below. Non-excitation magnetic brakes are mounted in all axis motor.
(1) RV-4F/7F series
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.
2) The J2 axis rotation is driven by the J2 axis motor <4> and reduction gears <5>.
3) The rotation of the J3 axis motor <7> arranged in the No.1 arm is conveyed to the reduction gears <9> via
the timing belt <8> to rotate the J3 axis.
4) The rotation of the J4 axis motor <10> arranged in the elbow is conveyed to the reduction gears <12> via
the timing belt <11> to rotate the J4 axis.
5) The rotation of the J5 axis motor <13> arranged in the No.2 arm is conveyed to the reduction gears <16> via
the timing belt <14> to rotate the J5 axis.
6) The rotation of the J6 axis motor <18> arranged in the No.2 arm is conveyed to the reduction gears <21> via
the timing belt <19> and gear <20> to rotate the J6 axis.
(2) RV-13F series
1) The J1 axis rotation is driven by the J1 axis motor <1> and reduction gears <2>.
2) The J2 axis rotation is driven by the J2 axis motor <3> and reduction gears <4>.
3) The J3 axis rotation is driven by the J3 axis motor <5> and reduction gears <6>.
4) The rotation of the J4 axis motor <7> arranged in the elbow is conveyed to the reduction gears <9> via the
timing belt <8> to rotate the J4 axis.
5) The rotation of the J5 axis motor <10> arranged in the No.2 arm is conveyed to the reduction gears <12> via
the timing belt <11> to rotate the J5 axis.
6) The rotation of the J6 axis motor <13> arranged in the No.2 arm is conveyed to the reduction gears <16> via
the timing belt <14> and gear <15> to rotate the J6 axis.
