HTR Series HTR Series

Hydraulic Rack & Pinion Rotary Actuator

This Design Series "C" actuator includes

improved features to provide greater
strength and service life under the most
severe conditions.

HTR Series Features

TAPERED ROLLER BEARINGS
Parker uses large capacity tapered roller bearings to support the integral pinion gear with output shaft. The large shaft and
bearings can support, relative to the actuator's size and weight, large axial and radial bearing loads and forces. Consider using
the HTR actuator as a motorized pillow block bearing.

DUCTILE IRON HOUSING

The high strength ductile iron housing is standard for HTR.9 through HTR600 actuators. The ductile iron material is shock
resistant and is more inclined to change shape than to crack when bumped, banged, or hit. The housing design allows for pilot,
front and back face, or base mounting options.

SAE SIDE PORTS

Parker uses the SAE ports as standard because they do not leak when properly installed. SAE side ports will eliminate the need
for an elbow fitting. This can be a cost saving convenience in most applications. SAE end ports are also available.

WEAR-PAK® PISTONS AND SEALS

Parker pilots high strength steel pistons onto the rack gear. Parker provides a choice of piston and seal arrangement which are
suggested on an applications basis. All piston designs use PTFE filled wear bands as the piston bearing. Most applications can
use the self energizing deep Polypak seal as the general purpose, virtually leak-free piston seal. We suggest trying our optional
vee packing seal for high pressure, high cycle applications.

CHROME ALLOY STEEL PINION AND RACK GEARS

Parker makes the gear sets from high strength, through hardened gear steels for high strength and medium durability. Through
hardened steels maximize shock resistance and bending strength for long life in most industrial applications. Parker has a case
hardened gear set option for HTR75 and larger actuators. Consider this option for those applications that do not fully require the
durability of the heavy duty, Mill Series actuators.

Specifications HTR Series

HTR Series
The HTR Series actuator incorporates many hydraulic and mechanical features that make this
actuator suitable for high production applications. These features include: high load supporting
tapered roller bearings; a chrome alloy steel rack and pinion gear set; a high strength ductile iron
or steel housing; and proven Parker Hannifin cylinder components. These features make the HTR
Series actuators robust and suitable for integration into the most demanding production systems.

The HTR Series actuators have been successfully employed in automotive plant production
machinery; machine tool equipment; plastics and rubber processing machinery; basic metals
production machinery and in material handling machinery.

The HTR Series actuator can be employed as an integral machine component. For example, the
actuator can simultaneously transmit torque and support the line shaft or the load. Such an
arrangement eliminates one set of external support bearings. For example: the optional cushions
can be employed to decelerate an external load. This feature eliminates the need for an external
deceleration device such as a shock absorber or a brake.

Additionally, the HTR actuator can simplify the installation of machine parts. For example: The
hollow shaft feature can eliminate a coupling. The actuator shaft can be connected to the line shaft
by means of a square shaft key; or the housing can be drilled and tapped to mount various
brackets.

The Wear-Pak® piston uses self energizing molythane piston seals. These are the only
pressurized dynamic seals. The pinion shaft uses low pressure seals. These polypak piston seals
can be inspected and serviced while the actuator remains installed on the machinery.

Effective filtration is vital to the long life and satisfactory PTFE
performance of a rotary actuator. If the piston seals of a rack Wear Band Deep
and pinion rotary are worn or damaged, fluid which leaks past Steel Piston Molythane
the piston will enter the gear housing. Piloted on Rack PolyPak

In the event of internal leakage into the gear housing, the

HIGH PERFORMANCE CUSHION (8)

(This option can be specified only with double rack units)

By combining the output/exhaust flow from two

cylinders, then routing it through a single cushion
bushing and cushion adjuster, cushion performance is
enhanced. The increased cushion flow results in
better control, doubles the cushioning torque, and
eliminates dangerous pressure intensification. This
unique circuit also eliminates two pipe or tubing tees.

OPERATION:
The work ports of a standard directional valve are
plumbed to ports C-1 and C-2. Port A-1 is plumbed
directly to A-2, and port B-1 is plumbed to B-2. When
pressure is applied to port C-1 (clockwise shaft
rotation), fluid is also directed through line A to the
other rack. Exhaust flow from B-1 through B-2 is
directed through the cushion bushing and cushion Work Ports Cushion Connection Ports

* Must deduct work (energy) done to overcome potential energy effects of load. WPE = TPE x θ , where θ is in radians.
** Extreme care must be exercised so that both cushions are adjusted equally for each direction or dangerous pressure intensification and
gear train stresses could result. (Suggest high performance cushion option.)

CUSHION DECELERATION CONTROL SUPPLEMENTAL INFORMATION

The cushion causes the resisting torque that can be used to KINETIC ENERGY BASIC FORMULA
decelerate a rotational load. Please note the cushion has to
provide enough resistance to control: drive torque caused by the KE = 1/2 Jmω2
hydraulic system pressure; plus the torque caused by gravity 2ΘA + ΘC + 2ΘD
pulling on the rotational load; and the kinetic energy associated ω = 0.0175 x
with the motion of the inertia load. Since the actuator's cushion Rotation Time (sec.)
where:
has to be able to control the sum of all three torque factors, we
KE = Kinetic Energy (in-lb)
suggest including cushion capacity as one of the actuator's
Jm = Rotational Mass Moment of Inertia (in-lb-sec2)
selection criteria.
See Section A, page 19 for formulas.
It is strongly suggested that proportional valves be used instead ω = Peak Velocity (rad/sec)
of cushions to control (decelerate) high inertial loads. This (Assuming twice average velocity)
provides the ability to reduce inlet pressure while generating ΘA = Acceleration Angle (deg)
deceleration pressure. It also allows for longer ramp times, thus ΘC = Constant Velocity Angle (deg)
increasing deceleration stroke. ΘD = Deceleration Angle (deg)

NOTE:
1. Static Bearing Load Capacities = Dynamic Values x 1.5

LUBRICATION
In general, low speed, high torque applications require class 5 or class 6 lubrication provi-
sions. Our assemblers use TEXACO MOLYTEX EP(2) extreme pressure grease to lubricate
our gear sets as our standard lubricant. The grease should be replaced with each major
overhaul.
Some high cycle applications with an operational system pressure below 1000 PSIG (69 Bar)
and with adequate mechanical shock control may successfully use the hydraulic fluid as the
gear train lubricant. We can modify the housing by adding a case drain line to carry away
excessive lubricant. Ensure the case drain connection is looped to ensure the housing
remains filled with lubricant.
High performance applications that feature high pressure and high cycle rates should
consider using an external lubrication circuit system to charge the gear set with clean, cool
lubricant suitable for class 3 or 4 service. An SAE80 or SAE90 lubricant circulating system
should be suitable. We can modify the housing for a lubrication circuit inlet and outlet.
Ensure the plumbing is run in such a way the housing remains filled with lubricant.

0.48 (12) A
The inductive type proximity switch provides end of rotation
indication. The non-contact probe senses the presence of the
ferrous cushion spear and has no springs, plungers, cams or
dynamic seals that can wear out or go out of adjustment. The
switch is solid state and meets NEMA 1, 12 & 13 specifica-
tions. For ease of wiring the connector housing is rotatable 1.38
through 360°. To rotate, lift the cover latch, position and (35)
release.

The standard proximity switch controls 50-230 VAC/DC loads

from 5 to 500 mA. The low 1.7 mA off-state leakage current
can allow use for direct PLC input. The standard short circuit
protection (SCP) protects the switch from a short in the load or
line upon sensing such a condition (5 amp or greater current)
by assuming a non-conductive mode. The fault condition
must be corrected and the power removed to reset the switch Model A, inch (mm)
preventing automatic restarts. HTR9 1.91 (48.5)
