V-belt pulley
V-belt drives are frictionally engaged
traction mechanism gears consisting in
their simplest form of two V-belt pulleys and V-belts. Transmission ratios
of 8:1 to 1:8 are possible with a power
of up to 1000 kW. With an extensive
calculation program we determine the
economically optimum drive from the
large number of combinations which are
technical feasible. Prices and delivery
times are favourable if V-belt pulleys
from the range in stock can be used.
DESCH V-belt pulleys
The DESCH V-belt pulleys have many
advantages: quiet running; good
damping of impact torques and rotary vibrations; rupture safety because
V-belts slip at over load; easy assembling; low-maintenance. In normal case
DESCH pulleys are of the material EN-GJL
200 and are standardised on the basis
of DIN 2211 and 2217 respectively.
V-belt pulleys with cylindrical hole are
balanced on one level quality grade
G 16 according to DIN ISO 1940;
dw < 400 mm with an operating speed
n = 1500 rpm; dw > 400 mm with
v = 30 m/s. Pulleys for taper bushes correspond to quality grade G 3 according to
DIN ISO 1940 balanced on one level; for
dw < 400 mm with n = 1.500 rpm;
for dw > 400 mm with v = 30 m/s. The
balancing is performed without groove
on a smooth balancing mandrel, which
corresponds to the half-wedge balancing
mode. Other types of balancing, such as
full-wedge, by agreement. We recommend: balancing on 2 levels G 6.3 for operating speed if the circumferential speed
is v > 30 m/s or the dw b2 ratio is < 4 and
v is > 20 m/s. If nothing different is
indicated, the ready-drilled holes of
the V-belt pulleys are given a tolerance
of H7 and are grooved for feather keys
according to DIN 6885/1. Max. outside diameter of pulleys 3.500 mm.

For safety reasons the circumferential

When selecting the V-belt profile and the
pulley diameter the following points are
important:
1. Do not go below minimum pulley diameter (p.8) (service life, economic efficiency)
2. Use standardised pulley diameter.
Select a standardised diameter at
least for the largest pulley of the
drive.
3. Note belt speed or max. circumfe-
rential speed of belt pulley. For
higher speeds other material grades can be supplied.
4. Special design possible.
In addition to V-belts for a wide variety
of profiles, we sell narrow V belts to DIN
7753, Part 1 (Fig.1) and USA Standard RMA/
MPTA in covered and raw-edged design
(Fig.3), compound V-belts (Fig.4) and
V-belts according to DIN 2215 (Fig.2). The
latter are not economic and should no
longer be used in new designs. V-belts
manufactured in series are resistant to
oils and greases provided these are only
present in small quantities, they are heatresistant to 70°C ambient temperature,
electrically conductive and dust-proof.
Taper bushes
with groove according to DIN 6885, Part 1
DESCH Taper bushes are used to fasten pulleys or coulpings to shaft. In the case of
V-belt pulleys this fastening is generally sufficient to transmit the power. An additional feather key connection is only necessary with extremely high load. Each
taper bush is equipped with a feather key groove for this purpose. The bushes can
be used with shaft tolerances of up to h11 with max. diameter of 30mm. Beyond
this up to h9. Detailed installation instructions are enclosed with each delivery.

1) The upper groove widths „b1“ are only precisely defined for V-belt pulleys according to DIN ISO 5290 for compound narrow V-belts. In the case of grooves according to DIN 2211 and DIN 2217, „b1“ depends in the groove angle.
2) The tolerance of the groove distance for non-successive grooves is double the value given for „e“. (not for compound V-belt pulleys)
3) Compound narrow V-belts only run in V-belt pulleys with a distance between grooves „e“ according to DIN ISO 5290.
4) Is in accordance with US Engineering Standard RMA/MPTA „Specification for drives using narrow multiple V-belts“

Weld-on Hub
Taper welded nubs are made of steel, drilled, countersunk and given a taper hole to enable
them to be mounted with standard taper bushes. The protruding flange provides a convenient possibility of welding hubs in fans, fanwheels, steel disks, chain wheel pulleys and
many other devices which have to be mounted permanently on a shaft. Welded hubs are
simple to install and are ideally suitable where heavy-duty conditions are encountered.
When the bolts are tightened, the hole is pressed together, thus fastening it on the shaft
in the form of a press fit. The type of design eliminates all mounting difficulties, as well as
preventing any loosening and migration on the hub during operation.

Bolt-on Hubs
Taper screw-on hubs have been designed for use with
taper bushes. They offer the favourable facility of
mounting fans, fanwheels and other devices firmly on
a shaft. DESCH screw-on hubs are made of grey cast
iron or steel and are phosphatised to provide additional
corrosion-proofing.
