Products of GX Series are semi-order-made ones that can meet the requirement of prompt delivery.
A product consists of two standard joints and a join slide(GXS, GXA).
A joint and a join slide are connected by a spring pin.
When machining around a shaft-hole is carried out, such as a key way or a tap hole, first draw a match mark, then pull out a spring pin, and disassemble a joint and a join slide. After completion of machining, reassemble precisely as they were so as to mate a match mark. (Products of type HJ-GX use a shear pin instead of a spring pin.)
When it is set up, yoke E of left joint and yoke F of right joint should be located symmetrically.
The following drawing shows the wrong setup, in which yoke E and yoke F are set in 90°phase difference. Please note that if it is set up in a wrong way, the output shaft cannot maintain the constant revolution velocity.
In case of total length change
Determine the use length (maximum length L1).
Calculate the length of intermediate shaft.
Calculate dimensions A and B with figures in dimension table of this catalogue, and find L3 using the following formula: L3=L1－(A+B)+(ℓ+H). Then, cut the shaft.
If you need to make the total length even shorter, cut the sleeve.
However you should maintain the engaged distance H between a shaft and a sleeve.
