Robot arm structure
An outline structure drawing of the 5-axis type robot arm is shown in
, and of the 6-axis type robot arm in
. Each part is as shown below.

) The J
1
axis rotation is driven by the J
1
axis motor <
1
> and reduction gears <2> arranged in the shoulder.
Non-excitation magnetic brakes are mounted in the J
1
axis motor <
1
>.
2) The J2 axis rotation is driven by the J2 axis motor <3> and reduction gears <4> arranged in the shoulder.
Non-excitation magnetic brakes are mounted in the J2 axis motor <3>.
3) The J3 axis rotation is driven by the J3 axis motor <5> and reduction gears <6> arranged in the upper arm
Non-excitation magnetic brakes are mounted in the J3 axis motor <5>.
4) The J4 axis rotation of 6-axis type is driven by the J4 axis motor <7> and reduction gears <8> arranged in
the elbow block.
5) The rotation of the J5 axis motor <9> arranged in the forearm is conveyed to the reduction gears <
11
> via
the timing belt <
1
0> to rotate the wrist housing and following parts.
Non-excitation magnetic brakes are mounted in the J5 axis motor <9>.
6) The rotation of the J6 axis is driven by the J6 axis motor <
