Ratchet Freewheels provide positive
one-way drive with high torque
capacity within a small unit.
A ratchet and pawl mechanism
is used with materials and heat
treatment selected for a long
operating life, with safe, positive
transmission. IRF's are suited
to low speed (up to 150 r.p.m.)
overrun applications where shock
loads may be encountered, such
as Agricultural machinery. Standard
stock units are available in
two configurations; as standard
sprocket for 1/2 inch pitch
chains, or with a drilled flange
to fit conveyor rollers, pulleys,
or wheels. Standard units have
threaded bore to cycle standards,
but a range of Adaptors enable
fitting to keyed shafting. IRF
clutches are also stocked in
part-assembled condition for
reworking to custom design,
including finish parallel bore
and keyseat. Many special Industrial
Ratchet Freewheels have been
manufactured to meet customers'
requirements with torques over
1,000 Nm. |

Steel
Adaptors for Industrial Ratchet
Freewheels
These adaptors enable easy assembly
of standard IRF's to conventional
keyed shafting.
Adaptors are solid bore, (except
F11 which has 15mm plain bore)
and can be finished bored and
keyed to customers specifications.

Standard
Sprag Clutches
"M" Series Sprag Clutches
"M"
series sprag clutches use precision
cams made of high chrome alloy
steel, hardened and honed for
accurate shape. A unique finishing
process ensures smooth cam surface
providing uniform contact with
both races for even load distribution
and prolonged clutch life. High
capacity bearings are used to
accommodate radial and axial
loads. The clutches are designed
to mount directly on through
shafts; the torque being transmitted
by a matching key provided with
each stock bore; the outer race
has a precision ground diameter
with tapped holes on each face
to enable the fitting of gears,
sprockets, pulleys, etc.
Four
types of clutch are offered:
MG Series
- Standard clutch for general
overrunning, backstop and index
applications, standard oil lubricated
with option of grease.
MI
Series - Has special
sprag assembly designed for
high speed indexing. Always
oil filled for optimum performance.
MO
Series - Fitted with
labyrinth seals for minimal
drag on higher speed overrun
and backstop applications. Always
grease lubricated.
MR
Series - Utilises
a special sprag cage arrangement
to allow high speed overrunning
of the outer race. Oil lubricated
clutch suitable as a higher
torque M 750 - 1000 alternative
to Roller Ramp clutches.
Vertical
Shafts - Clutches
suitable for vertical shafting
can be supplied - contact Cross
& Morse sales office for technical
advice.
High
Speed/Temperature Operation
- Clutches can be provided with
a patented venting system for
applications subject to high
temperature variation or overrunning
at high speed. |
