- Clutches
OLDHAM COUPLING
DRIVE
4Z4-009
Type: Clutches
Drive illustrates motion transmission requiring coupling of two, offset, parallel
shafts running at the same speed. In the Oldham coupling, perpendicular projections or
keys on the two shafts engage correspondingly shaped perpendicular slots or keyways on
floating, intermediate member. Motion of intermediate member adjusts to accommodate shaft
offsets. Price: $43.89
DOUBLE-ACTING
TAPERED CLUTCH
4Z4-019
Type: Clutches
Device illustrates principle of clutching and declutching in machine drives. Cone-type
friction clutch with two-cone construction couples driving and driven shafts in either of
two positions, thus varying speed ratio. Indicators on shafts useful in studying speeds
and basic motion relationships in clutch drives. Price: $103.51
JAW-CLUTCH DRIVE
4Z4-041 Type: Clutches
Drive illustrates principle of a serrated (jaw) type clutch, which serves to couple or
uncouple crank-operated input member to gear-mesh actuating output shaft. Basic clutch
construction and motion characteristics of drive illustrated by model. Price: $78.41
DOUBLE-JAW CLUTCH
DRIVE
4Z4-042
Type: Clutches
Drive illustrates use of double-clutch and gear arrangement using jaw clutches to
obtain different speed ratios between input and output shafts. Indicators serve to
illustrate speed and motion relationships involved in clutching operations, such as are
found in a variety of industrial drives and automatic machinery. Price: $108.72
CENTRIFUGAL-CLUTCH
DRIVE
4Z4-043
Type: Clutches
Drive illustrates principle of a centrifugal clutch. Geared input and output shafts
connected through a double clutch arrangement including a centrifugal clutch. Unit
illustrates principle of transmission control using a shifting action governed by speed. Price:
$118.94
SINGLE-ACTING
TAPERED-CLUTCH DRIVE
4Z4-045
Type: Clutches
Drive illustrates principle of a cone-type friction clutch, coupling driving member
(crank-operated input shaft) through a gear train to output shaft. Indicator on output
shaft serves to illustrate motion characteristics in a combination gear-and-clutch drive. Price:
$78.41
DOUBLE-ACTING CLAW
CLUTCH
4Z4-059
Type: Clutches
Model illustrates the principle of clutching and declutching in machine drives. The
clutches couple the input and output shafts through two gear pairs, thus the position of
the operating lever determines the speed ratio between the input and output shafts.
Indicator on the output shaft is useful in studying speed ratios and clutch action. Price:
$108.72
COMPACT TOOL KIT
4Z4-0ST
Five piece kit consisting of two screw drives and three wrenches. Price: $12.95
