Instruction Manual for 70C, 70D 75C and 75D

These instructions must be read thoroughly before installing or operating this product.

DESCRIPTION

FLEXIDYNE dry fluid couplings and drives are unique concepts

to provide soft start and momentary overload protection for all

types of driven equipment. Standard EMAB motors with RPM

base speeds of 1750, 1160 or 860 are commonly used with a

FLEXIDYNE coupling or drive, yet other available power sources

may be used with the FLEXIDYNE mechanism.

The dry "fluid" in the FLEXIDYNE housing is heat treated steel

shot. A measured amount, referred to as flow charge, is added

into a housing which has been keyed to the motor shaft. When

the motor is started, centrifugal force throws the flow charge to

the perimeter of the housing, packs it between the housing and

the rotor which in turn transmits power to the load.

After the starting period of slippage between housing and rotor

the two become locked together and achieve full load speed,

operating without slip and with 100% efficiency.

Consequently, the motor accelerates instantly to base speed,

while the load starts gradually and smoothly.

WARNING: Because of the possible danger to persons(s) or

property from accidents which may result from the improper

use of products, it is important that correct procedures be

followed. Products must be used in accordance catalog.

Proper installation, maintenance and operation procedures

must be observed. The instructions in the instruction

manuals must be followed. Inspections should be made

as necessary to assure safe operation under prevailing

conditions. Proper guards and other suitable provided, and

are neither provided by Baldor Electric Company nor are

the responsibility of Baldor Electric Company. This unit and

its associated equipment must be installed, adjusted and

maintained by construction and operation of all equipment

in the system and the potential hazards involved. When risk

to persons or property may be involved, a holding device

must be an integral part of the driven equipment beyond the

speed reducer output shaft.

Couplings and Drives

COUPLINGS:

Install coupling flange on motor shaft and drive housing

mechanism on driven shaft in accordance with the instruction

manual for the Taper-Lock® bushings.

NOTE: The coupling flange must be mounted on motor

shaft (not driven shaft) to allow proper operation of the

FLEXIDYNE coupling.

Shaft ends must not protrude beyond bushing ends. Install

coupling disc over pins on drive housing mechanism. Position

the motor and the driven unit so that the spacer buttons on the

coupling disc slightly contact the coupling flange. Reference

Dimension A on Parts Replacement Drawing.

(A = 5/8" on size 70C; A = 3/4" on size 75C)

For longest FLEXIDYNE coupling life, it is always desirable to align

coupling as accurately as possible at initial installation. Check

alignment by laying a straight edge across the coupling flange

and drive housing at several points around the circumference.

NOTE: Driven shaft must not touch housing hub.

DRIVES:

Motor

Shaft

Install the FLEXIDYNE special bolt-on sheave on the driven hub.

Use screws and lock washers provided with the FLEXIDYNE

drive. Torque screws to 160 inch-pounds.

Stake motor shaft key in place and slide FLEXIDYNE drive onto

the motor shaft, with collar as close to the motor as possible.

Tighten key set screw securely against motor shaft key. Tighten

shaft set screw securely against motor shaft.

NOTE: The sheave is the output of the FLEXIDYNE drive, do

not input power to the FLEXIDYNE drive through the sheave.

In other words, do not mount the FLEXIDYNE drive on the

driven shaft.
