Dimensioning
3.6.1 Inspection
The required protection classes can be achieved for example by the following measures:
- Use surface bonding agent between motor flange and adapter plate
(When doing so, check whether grounding is required!)
- Use sealing plates between motor flange and adapter plate to seal the through-holes of the
adapter plate.
Sealing plates are available upon request from
WITTENSTEIN alpha GmbH
.
3.7
Information about the lubricant
Incorrect dimensioning and inspection may lead to explosions.
Observe all instructions in this chapter.
Use the dimensioning information specified in the "Information" or "Detailed
dimensioning" chapter of the general catalog, or contact
WITTENSTEIN alpha
GmbH
.
During dimensioning, note the reduced performance data in Chapter 10.6
"Technical specifications".
Our Customer Service department is available to answer any questions.
Note the instructions in Chapter 7.2.4 "Replacing the gearbox"if the calculated
bearing life is under 30,000 h
.
Prevent gearbox overloading by the motor by limiting motor current and motor
speed.
Clarify the chemical stability of the gearbox for every individual case so as to avoid
a premature failure of a shaft seal or corrosion on the gearbox.
This also includes water and steam, which can cause corrosion. Contact
WITTENSTEIN alpha GmbH
about this.
Ensure that the connection of the motor to the gearbox corresponds to the
required protection classes (according to EN 60529):
- IP6x in dust atmospheres,
- IP54 in gas atmospheres.
All gearboxes are permanently lubricated by the manufacturer with
synthetic gear oil (polyglycols) or with a high-performance grease (see
identification plate). All bearings are lubricated for life at the factory.
