Technical information 

Benzler worm gears BS 35-71 have a symmetrical gearhousing 

manufactured in aluminium. BS 88 and 112 have 

a gearhousing of cast-iron. 

The worm wheel is made of centrifugal cast tinbronze and 

the worm screw is case-hardened and ground. 

All motor connections are according to IEC-standard and 

for BS 40-112 with elastic coupling. This means the 

following advantages: 

• The worm screw is mounted with two separate bearings 

and are not connected with the motor bearings. This 

means longer lifetime and a smoother drive.. 

• Soft start and stop with elastic coupling for size 40-112. 

• No oil leakage in to the motor. 

• Possibility to change motor without dismounting the 

gear.. 

• Any type of motor with IEC-flange can be used.. 

The worm geared motor is available for mounting on a 

base, flange or torque arm and can be installed in any 

position. 

The gear can be combined with Benzlers’ remaining 

range of helical and worm gears to provide very low 

output speeds. All data given in this catalogue applies to 

ABB standard motors and Benzlers brake motors. 

Motorflanges 

The motorflanges up to IEC-size 112 are made of 

aluminium and are available in B5 and B14, larger 

motorflanges are made of cast-iron and available in B5. 

A finished bore shaft coupling is always delivered 

together with the motorflange. 

Feet 

The feet can be mounted without modification. 

Output shaft 

Single or double output shaft can be mounted into the 

hollow shaft. The output shafts are locked into position 

with keys and retaining rings. BS 88-112 has as standard 

execution, a single output shaft or a hollow shaft. 

Output flange 

An output flange can easily be mounted on to the gear. 

The BS 40-71 gear casing can also be mounted onto a 

wall or foundation and bolted through the 4 bolt holes in 

the gear casing. 

Torque arm bracket 

The hollow shaft gearboxes can be supplied with torque 

arm bracket and torque arm. 

Fan 

BS 88/112 have fan as an option. 

Painting 

BS35-71 is normally delivered without painting. BS 40-71 

can be delivered according to environmental 

classification M2-M3, see page 58-59. 

BS88-112 is normally delivered with standardpaint, 

which is an alkyd paint in Benzler blue colour (RAL 

5015).

Selection of gears and gearmotors 

Power and torque ratings for gears on page 40-47 apply 

to service factor 1.0. Service factor for geared motors can 

be found after the output speeds. Service factor 1.0 is 

valid for continous operation 8 hours/day without shocks 

and with 10-200 starts per hour. The inertia of the driven 

machine is less than 20% of the electric motor. 

Occasional shock loads may not exceed 1.8 times the 

gear rating at service factor 1.0. 

Determination of sizes 

1. Determine the demand power or torque, P e or T 2b 

ratio (i) or output speed (n 2 ). 

2. Based on type of load/driven machine, operating 

hours/day and number of starts/hour, select service 

factor fb (page 6-7). 

3. Calculate T 2 ≥ T 2b x f b . 

4. Choose gear on page 40-47 according to following: 

T 2 ≥ T 2b x f b at required ratio (i) or speed (n 2 ). 

Note the efficiency. 

For example BS40 ratio 6,67:1, code A 

η = 86% at n 1 = 1430 rpm. 

5. Calculate P 1 =P e x f b x 1 η 

Choose a size larger motor P m ≥ P 1 

For example P 1 ≥ 0,42 kW choose 0,55 kW. 

6. Choose a worm gear motor on pages 12-24. 

For example BS40A with a motor size 80A4. 

7. Check that occasional shock loads do not exceed 1.8 

times the gear rating at service factor 1.0. 

T 2max ≥ T 2 x 1,8 

8. Check that the thrust and overhung loads are not 

exceeded. 

9. Check that maximum input speeds and thermal ratings 

are not exceeded. 

10. For conditions other than above described, for 

instance extreme environments, high inertia 

systems or other, please contact your nearest 

Benzler office.

Reversing 

Dynamic self locking means that a force applied on the 

output shaft of the gear can not continue to drive the gear 

when the motor has been stopped. 

Dynamic self locking is only possible at very high ratios 

and low output speeds. None of the worm gears 

produced by BENZLERS is dynamic totally self locking. 

Static self locking means that a force applied on the 

output shaft of the gear can not start a movement. 

When driving loads with high inertia care must be taken 

to achieve a braking time long enough to prevent 

overload on the gear. 

When a worm gear is used in an application with short 

braking time a worm gear that is "dynamically reversible" 

is normally the best selection. 

Information regarding lead angle for BENZLERS worm 

gears are given on the following page.

Efficiency 

The efficiency of the gear has to be considered when a 

worm gear or a worm geared motor is chosen. For 

intermittent duties it is necessary to increase the motor 

power to be able to compensate for the low efficiency 

during start. 

Also consider that the highest efficiency is reached after

Worm Gear 

with environmental 

With BS (size 40-71) classified acc to 

environmental class we are able to 

recommend the gears for installation in 

ambient conditions where normally 

classification 

only materials in stainless steel are 

accepted. The gears are classified acc 

to environ-mental class M2-M3, Swedish 

standard stBK-N4. 

58

Advantages: 

• No corrosion 

• Low weight (aluminium) 

• High rating 

• IEC-standard 

• High surface finish • Modern design 

• No maintenance • Easy handling 

• Large number of motor alternatives 

Product specification 

• coated gear case, flanges and feet 

• stainless steel bolts in gear housing 

• stainless steel hollow shaft ( SS 2346 alt. 2382) 

• stainless steel output shaft 

• surface for seal ring protected by stainless steel sleeve 

(SS 2333) 

• Seal rings of viton 

• ratings acc to catalogue 

Type of coating 

The coating is a recently developed surface coating 

method for aluminium. 

The coating means that the material surface is, by a 

chemical process, converted into an aluminium oxide, 

which gives a very hard, ceramic, surface finish. 

The oxide layer is then impregnated and coated with 

plastic. With heat treatment a very strong and resistant 

connection between oxide and plastic is created. 

Unique coating qualities: 

• high resistance against corrosion 

• very hard and resistant against wear 

• Iow tendency to be sticky 

• hygienic 

Application examples 

• food industry 

• paper and cellulose industry 

• pharmaceutical industry 

• chemical industry 

• defence industry 

• marine and mobile installations 

• all outdoor installations

Benzlers "electronic" catalogue 

We at Benzlers has as one of our goals to continuously help our customers to increase their 

profitability and efficiency. As a step on this road we have made programs for CAD and PC with 

drawings and calculation programs for our whole range of gears, which will simplify your selection 

of gears. 

This electronic catalogue will help you with; 

Selection of gear and geared motor. 

Documentation of selection and related power demands etc. 

Detail drawing and Layout drawing. 

With these programs you will win considerable amount of time in the design stadium and will gain 

higher development speed in your own business. Except gaining time the selection will secure that 

the optimal gear combination is selected in each and every case. Thereby the risk for expensive 

breakdown will decrease to a minimum and also unnecessary high cost if too big gears are selected . 

61

Mounting 

General 

1. The gear should be placed on a flat and solid 

foundation. 

2. Sprocket, pulley or coupling on shaft can not be 

mounted with force. This will damage the gear. 

3. To avoid increasing load on shafts and bearings, the 

gear and the driven machine should be carefully 

aligned, even if an elastic coupling is used. 

Hollow shaft gears 

1. The gear is normally mounted on a shaft with tolerance 

js6. The hollow shaft have tolerance H7. 

Grease the shaft with Molykote BR2 or equivalent 

before the gear is mounted. The gear shall not be 

mounted with force. 

The gear shall be locked against axiel movement. Set 

screws in hollow shaft can be used for BS88 and 112. 

4. If sprockets are used on the output shaft the preferable 

direction of pull should be such that the gear housing 

willbe pressed towards the foundation. 

5. When situated outdoors or working under adverse 

conditions as heat, dust or damp, the gear must be 

provided with sufficient protection, but the cooling air 

circulation must not be unduly restricted. 

Lubrication 

Before delivery BS40-112 are filled with synthetic oil - 

Mobil SHC 634 and BS35 with synthetic grease - Mobil 

SHC 007. This type of lubrication is extra suitable for 

worm gears. 

At normal condition the oil/grease never needs to be 

changed. 

Ambient temperature -30°C - +30°C. 

Maintenance 

1. Benzler worm gears are lubricated for life with synthetic 

oil/grease and are therefore maintenance free. 

3. The worm gears shall under no circumstances be 

entirely filled with oil or grease. 

2. Check that there are no leakage. 

Running in 

1.The gear should be run under low load conditions 

during the first 10-30 hours. Then the load should 

gradually be increased to full load. 

2.The length of the running-in period depends on the size 

of the gear and the actual working conditions. 

3. When increasing the load the temperature of the gear 

can exceed the ambient temperature by 60-70° C. Oiland 

geartemperatures of 95-100° C are harmless and 

have no influence on the function af the gear. When 

the temperature exceeds 100° C special sealrings must 

be used. 

4. Gears which are not used for a long period should be 

run for short periods, approximately every third month.
