Load limiting devices - Load limiting devices are not
3*4.5.5
applicable, However, under maximum voltage conditions, the stall torque
of the motor for the actuator shall not exceed 350 percent relative to
maximum rated load of the motor.
Anti-rotatio n device - Means shall be provided within
3.4.6
the actuator to provide anti-rotation to the limit of maximum operating
.
load and maximum dynamic stall torque of the motor.
3*4.7
E&zSl&-
erating stro ke - The electrical stroke shall be
3.4.7.1
infinitely adjustable from full stroke down to 1/2 inch. This minimum
1/2 inch stroke shall be available anywhere within the full rated stroke
specified in the applicable MS drawing.
Overtravel - The overtravel of the actuator stroke under
3.4.7.2
all operational loads, voltage frequency, and environmental conditions
shall riot exceed the limit specified on the applicable MS drawing. Over-
travel is defined as movement after interruption of electrical power.
- Non-jamming stops shall be provided
Mechanical
3.4.7.3
to limit overtravel at the ends of the rated stroke. Adjustability of
such stops for shorter operating strokes is not required.
Endplay - Actuator endplay measured between attaching .
3,4,8
fittings shall not exceed .005 inch full indicating reading (F.I.R.) when
new or .010 inch F.I.R after completion of rated life when measured under
10 pound reversing load.
Reversibility - The power screw shall be
mechanically
3.4.9
irreversible without the aid of a brake for any load up to
the static
limit load exclusive of any vibration. Actuators shall be
electrically
reversible and mechanically irreversible under any adverse
combinations
--. of_operating and.snvi.smnmentaZ conditions specified herein.
Movable end f- - Movable end fitting shall be
3.4.10
as specified on applicable MS drawings. When a rod end fitting is speci-
fied$ plain self-aligning bearings per Specification MIL-B-5629 shall be
provided. The fitting shall be secured with a locking device conforming
to Standard NAS 1193.
- The actuators shall operate within
3.4.11
O
the speed-load ranges defined by the applicable MS drawing.
