12. Place an external stopper in a position that is away from the rotating shaft.
If the stopper is placed near the rotating shaft, the torque that is generated by the product itself will
cause the reaction force which is directed to the stopper to be redirected and applied to the rotating shaft.
This will lead to the breakage of the rotating shaft and bearing. As a result, it could pose a hazard to
humans and damage the machinery and equipment.
Precautions when Using External Stoppers
・
Be sure to install external stoppers in the proper places. Installation in the wrong place can result in
equipment breakage, which could damage other equipment or cause human injury.
・
Install external stoppers within the range of the rotating angle.
Installing an external stopper at the maximum rotation angle may result in an inability to fully absorb the
kinetic energy generated, and damage to equipment may occur.
・
Angle adjustment is available for this product. When using an external stopper, set in a position so that
that the adjusting bolt does not collide into the piston.
Precautions when Converting Rotational Motion to Linear Motion
When using a link mechanism, etc., to convert rotational motion to linear motion, and determining the
operation end using the stopper on the linear motion end (see below), a small value for
θ
at the operation
end may result in the torque of the rotary actuator causing excessive radial load to act on the output axle,
and equipment breakage may occur.
Install a stopper on the rotation motion side, or increase the value of
θ
at the operation end, to make sure
the load generated does not exceed the allowable value for the product.
- 7 -
Install the stopper at a sufficient
distance from the rotating shaft.
The external stopper becomes a
fulcrum, resulting in the load
’s
inertia force being applied to the
table as a being moment.
If an external stopper is installed
on the opposite side of the load,
the inertia force generated by
the load is applied directly to the
table.
