Efficiency rating
The efficiency ratings indicated in the output tables for the cylindri-
cal worm gearbox are average and/or guideline values. They apply
to warm-running, well-run-in cylinder worm gearboxes with roller
positioning, proper lubrication and a tractioning worm shaft at the
corresponding operating output speed under nominal load and con-
tinuous operation. The efficiency rating increases proportionally to
the increase in running speed (vg) on the splicing (output speed and
sizes influence), with increasing centre-increase angle m
(that is to
say, with a decreasing transmission ratio i) and with improvement in
the surface quality of the tooth flanks for the worm shaft. Based on
previous experience, the efficiency ratings for a new gearbox (accord-
ing to the prevailing transmission ratio) are lower than indicated in the
output tables. These are to be multiplied by the following factors:
S 40.1 S 100.1/SS 50.1 SS 250.1
i (worm) Factor
4 ... 14 0.97
14.5 ... 27 0.93
ab 28 0.87
SST 97 SST 150
i (worm) Factor
4 ... 11 0.97
13.5 ... 19.5 0.93ab 27 0.87
A good run-in is a decisive factor in the output and lifetime of the
Efficiency ratings and problems for the self-locking effect
transmission. When operating conditions deviate greatly from the
indicated conditions (i. e., in the event of very short running times
followed by long breaks) the indicated efficiency ratings cannot be
attained. Therefore, we kindly request that you consult us before
taking further action.
Actuation to the fast mode
The efficiency rating with a tractioning worm wheel (transmis-
sion to the fast mode) is calculated as follows:
= 2-
With that, the overall efficiency rating h is always lower than with
a tractioning worm shaft. Based on this premise, it is apparent that
multiple-gear worms, due to their favorable efficiency rating for
GFC worm wheel sets, starting at the 4-gear worm enable actua-
tion from the worm wheel side (that is to say, actuation to the fast
mode).
Self-locking capacity
For worm gearboxes, one differentiates between the static and
dynamic self-locking effect. Static self-locking effect is applicable
when the start efficiency rating A0.5. A start of the worm shaft
with a tractioning worm wheel is then impossible. Due to external
initiation of oscillation, this self-locking effect can be (under certaincircumstances) cancelled out, which means that the worm shaft can
be started when the worm wheel is tractioning. The dynamic self-
locking effect (self-locking capacity when running) applies when
>>

Introduction
GFC Product Catalog 2012 /9
the operating efficiency rating 0.5. This takes effect in worm
gearboxes (according to the prevailing surface quality and tooth-
bearing size at centre-increase angles ranging from = 2.5 to 4.
Self-locking worm gearboxes are inefficient due to their poor over-
all efficiency rating and the correspondingly high loss of output
(particularly considering the extensive installation space and longpower-on times). In those actuator situations in which the self-lock-
ing effect is required, one should always verify whether the instal-
lation of a return block or a brake is the more practical solution. A
self-locking gearbox cannot replace an actual brake.
Self-locking capacity for the GFC worm gearbox, depending
on the transmission ratio:
>> transmission ratio i = 5 to 25 no self-locking effect
>> transmission ratio i = 31.5 to 50 static self-locking effect,
possible return under vibration
>> transmission ratio i = 63 to 100 static self-locking effect,
return only possible with limitations when vibration occurs
If self-locking is required, please contact GFC.
Start efficiency rating A
The start efficiency rating A for a cylindrical worm gearbox is
(due to the large tooth-friction coefficient Z for low running
speeds) is always less than the ef ficiency rating at operating output
speed under nominal load and continuous operation. For starting a
worm gearbox under load (due to the lower start ef ficiency rating)
a greater actuator torque T1Ais necessary. T1Ais calculated as fol-
lows:
T1A
= in Nm
The start efficiency rating is (just as the operating efficiency rat-
ing) dependent on the width of the centre-increase angle for the
worm shaft. Here, too, the principle applies that a wider centre-
increase angle positively influences starting. The start efficiency
ratings indicated in the following are guideline values (just as theoperating efficiency ratings in the output tables). They apply to the
run-in gearbox lubricated with synthetic oil. For a new gearbox, the
following start efficiency ratings apply.

The values indicated in the selection tables (output and torque)
apply to warm-running, well-run-in and properly lubricated gear-
boxes, with nominal load and tractioning worm shaft under the
following conditions:
>> Continuous operation (S1) with consistent loads and 8 hours of
daily operation
>> Ambient temperature: 20Celsius
>> Lubricant temperature: 100Celsius
>> During the start, the 2-fold actuator torque is transmitted; in the
process, five starts per hour are permissible. Operating conditions
which deviate from this limit value must be taken into account with
certain factors upon selection. The indicated factors are guideline
values. A selection of worm gearboxes should preferably be made
according to the actuator torque for the working machine. Here,
one must differentiate between mechanical and thermal wear:
The torque Tais calculated from the equation

Permissible shaft loads
Determination of the radial forces exerted upon theactuator and/or the output
In the determination of the generated radial forces, the type of
transmission elements applied to the shaft end must be taken into
account by allowing for the corresponding transmission elements.
Based on experience, the following values can be assumed:
Transmission element Remark Factor fZ
Gear wheels < 17 gears 1.1
Sprocket wheels < 13 gears 1.4
Sprocket wheels < 20 gears 1.2Y-belt pulley Influence of preload force 1.7
Flat-belt pulley Influence of preload force 2.5
The existing radial load on the gearbox shafts iscalculated according to the following relationship:
FR

The conditions for the torque ratings were observed.
The radial forces indicated for these product lines rule out the simulta-
neous utilization of axial forces FA and apply only for unilateral loads.
These values were determined considering the least-favorable force-
exertion angle a and the rotation direction in the event of exertion of
force in the centre of the shaft ends. In cases of applicable loads which
exceed the limit values indicated in the table or upon the occurrence
of combined forces, an individual re-calculation with indication of the
force-exertion angle and the rotation direction is recommended. In
these cases, we kindly request that you ask for this option. Axial forces
can absorb up to 50% of the permissible radial forces.

>> MODULAR UNITS AND SPECIAL SOLUTIONS
GFC worm gear sets consist of case-hardened and ground worm shafts
combined with worm wheels made of high-quality, wear-resistant
centrifugally cast or continuous cast bronze. Worm gear sets are
characterised by shock-resistant, vibration-absorbing and low-noise
gear teeth and provide large transmission ratios within a
single stage. Self-locking at standstill is possible. We produce
worm gear sets in standardised type ranges or according to
the specifications of our customers. Sophisticated and
individual solutions are provided by using modern and
high-precision gear cutting machines and by continuouslyimproving our technologies.

>> COST-EFFICIENT SOLUTIONS FOR HIGHEST
DEMANDS
GFC worm gear units have excellent characteristics such as low-noise
and shock-absorbing torque transmission. The hardened and ground
tooth flanks of the worm shaft as well as the high-quality bronze of
the worm wheel ensure low wear and a long
lifetime due to the high production quality. The
simple but nevertheless efficient design offers
substantial advantages in terms of space com-
pared to other gear types.
