3.3
Sealing air (optional)
The rotary table has a connection for the sealing air between the housing and the
table top (for position and connection thread see the dimensional drawing).
The necessary compressed air must be provided by the supply facilities of the
operator.
The sealing air must be regulated and purified by means of a control valve with a
filter.
The sealing air pressure must be maximum 0,05 MPa (0,5 bar; 7 psi).
If the pressure of 0,05 MPa (0,5 bar; 7 psi) is exceeded, this
can cause serious damage to the rotary table.
The sealing air must correspond to quality class 4 according to DIN-ISO 8573-1:
•
Solid matter: maximum particle size 15 µm; maximum particle density 8 mg/m
3
•
Oil content: maximum oil concentration - 5 mg/m
3
•
Water content: maximum pressure condensation point +3 °C

Operating parameters
Acceleration and deceleration time in the case of adjustable drives:
•
In the standard, the rotary table for the connection to the mains network is
designed with 3x 400V / 50Hz. During operation with the frequency converter
the characteristic values featured in the specification must be observed.
•
The acceleration and deceleration times are determined by the operating cam.
A ramp is not required on the three-phase braking motor.

Assembly units
3.5.1
Rotary table
The table top is operated with various motor types and operating cam.
This means that rotational movements can be performed in any direction, however
using the angle stipulated by the operating cam.
The acceleration and deceleration is determined mechanically by the operating
cam's angle of elevation. No ramp is therefore required on the motor.
The positioning precision is determined by the operating cam holding phase.
A drill pattern is included in the table top.

diagrams, see Chapter 16 annex .
3.5.2
Cam roller gearbox
The operation is generated from the drive motor via a gearbox and cam drive to the
table top. The movement follows a modified sinusoidal shape.
The cam rollers are pretensioned on both sides at the operating cam.
