Intended use
The gearbox serves to convert torques and speeds. It is suitable for all industrial applications.
In food processing / pharmaceutical / cosmetics, the gearbox may only be used next to or under the
product area. Product-specific deviation regarding the positioning and mounting position are
described in Chapter 3 "Description of the gearbox".
The gearbox has been constructed according to current technological standards and accepted
safety regulations.
To avoid danger to the operator or damage to the machine, apply the gearbox only for its
intended use and in a technically flawless and safe state.
If you notice any altered operating behavior, check the gearbox in accordance with Chapter 9
"Malfunctions".
Read the general safety instructions before beginning to work (see Chapter 2.5 "General
safety instructions").
Screw connections between gearbox and attached component such as motors have to be
calculated, dimensioned, mounted, and tested according to current technological standards. Use
the VDI directives VDI 2862 sheet 2 and VDI 2230 for example.
The tightening torques recommended by us can be found in Chapter 10 "Appendix".
Deviating from the recommendations in Chapter 5 "Assembly", washers may be used if the material
of the screw surface features a too low interface pressure.
The hardness of the washer needs to match the property class of the screw.
Take into account the washer for the screw calculation (joint, additional compression set,
surface pressure under screw head and under washer).
The gearbox can be used in the potentially explosive atmospheres defined in
Chapter 3.4 "Ex model".
Observe the instructions on the name plate and the appendix on the written
certificate of conformity.
The gearbox is manufactured and certified for use in potentially explosive
atmospheres in compliance with standard DIN EN ISO 80079 and the following EU
Directive:
-
2014/34/EU
Strictly observe the restrictions on speeds and torques (see Chapter 10.6
"Technical specifications").
Our Customer Service department (technical customer service) is available to
answer any questions.
The gearbox is intended for installation on motors that:
- correspond to type B5 (in the event of deviations, consult our Customer Service
department [Technical Customer Service department]).
- have a radial and axial runout tolerance according to DIN EN 50347.
- have a cylindrical shaft end with tolerance class h6 to k6.
For motor shaft diameters of 55 mm and up, m6 is also permissible.
- Feature at least the same temperature class as the gearbox (see also Chapter 3.2
We recommend this temperature class and higher, because the gearbox may
not be allowed to exceed the maximum permitted housing temperature under
normal conditions (see chapter 10.4 "Specifications for startup and operation").
The gearbox can be heated additionally through heat connection to the motor,
and thus reach a higher housing temperature. The performance of our gearbox
in explosion-risk areas would therefore no longer be guaranteed.
