MECHANICAL INSTALLATION

A. GENERAL OVERVIEW

The following instructions are meant to assist in proper installation of

Dynapar brand, Series HS35R hollowshaft encoders. The encoder is a

speed and position transducer that when mounted to a rotating shaft,

produces output pulses that are directly proportional to the shaft speed

and direction. The hollowshaft encoder is attached to the motor shaft

by using a clamp down collar. The HS35R can accommodate several

machine shaft diameters by selecting the appropriate bore size. During

installation, certain physical properties associated with the mechanical

coupling must be observed to ensure a long operation life of the

encoder.

B. SHAFT EXTENSION

Solid shaft preferred, keyway allowed; flatted shaft must not be used.

The minimum shaft engagement length that will allow support to

encoder housing is 1.25", Shaft engagement length of 1.60" (40.6mm)

or longer is recommended for reduced wobble. The longest shaft

length as measured from the mounting face that will allow installation

of the shaft cover is 2.60" (66 mm) maximum. Installations that employ

a press-fit or screwed-on stub shaft adapter should align the stub shaft

to 0.002" TIR or less with a dial indicator

C. TETHER POINT

For general industrial machinery and C-face motor installations, locate

the tether hole at the nominal bolt circle location. The tether holes are

slightly elongated, to allow for hole location tolerance and arcing of the

tether, if the hole location is not flush with the tether surface.

STEP 1: PREPARATION AND RECOMMENDED TOOLS

Disconnect power from equipment and encoder cable. Ensure that you

have the proper tools. Typical tools that may be needed depending on

the options chosen are:

#2 Phillips Screwdriver; 5/32" Hex Wrench(US); Caliper Gauge; Dial

Indicator Gauge; 3/8", 1/2" or 1/4" T- handle Wrenches (tether

options); Dynapar M100 encoder tester.

STEP 2: CHECK AND CLEAN THE MATING SHAFT

Ensure that the mating shaft is within proper tolerances.

Recommended mating shaft diameter tolerances should be nominal

+0.0000"/-0.0005" [0.00 to -0.013mm] and shaft runout TIR should be

under 0.002".

Clean the mating shaft of any burrs and check that mating shaft

engagement is at least 1.25" inside the encoder shaft. Using a dial

indicator gauge verify that the motor shaft Total Indicated Reading

(TIR) is less than 0.002" [ 0.05 mm].

STEP 3: INSTALL ENDCAP

END CAP SCREWS (3X)

The encoder ships with an endcap to cover the back end of the

encoder body, and although optional, is reccommended for additional

environmental protection. To install, remove the factory installed three

screws at the back of the encoder, properly discard the removed back

plate and the three screws. Unpack the endcap, gasket and the three

screws from the factory supplied kit. Align the three holes and fasten

the gasket and end cap to the encoder body as shown.

Rotate the tether to the required orientation and tighten the tether arm

to the encoder body using the three screws provided .The hollowshaft

series encoder tethers can be rotated in 15 degree increments so that

connector or cable exit can be conveniently located.

STEP 5: INSTALL WASHERS ON TETHER

WASHERS

Slide the flat nylon washer on the side away from the bend and the

flanged nylon washer on the side of the bend and press them together

until they are fully seated in the tether hole. One steel washer is to be

used on each side of the nylon washer.
