Stepping motions for index driving and rotary index tables
Index drives and rotary index tables execute a stepping motion on the output shaft when the input shaft turns continuously.

Cycles/min: up to 1.000
Torque: up to 13.000 Nm
Design: as installation kit or as housed unit with and without drive
Selection:
Rotoblock index drive (dimension sheet) (German)

RIGIDIAL - rotary index table
The MIKSCH RIGIDIAL rotary index table is based on a globoidal cam. The input shaft is positioned rectangular to the axis of the rotary table.
Standard number of stations:2-32
Cycles/min: up to 100
Torque: up to 20.000 Nm
Design: as housed unit with and without drive

CF 2 - index drive
The MIKSCH CF 2 index drive is based on a cylinder cam. The input axis is rectangular to the output axis. The direction of rotation of the input and output shafts can be selected at will.
Standard number of stations:3-24
Cycles/min: up to 300
Torque: up to 1.500 Nm
Design: installation kit
Selection:

INTERMICO - rotary index
The MIKSCH INTERMICO rotary index table is based on a cylindrical cam. The input shaft, as with the RIGIDIAL rotary index table, lies rectangular to the axis of the rotary table.
Standard number of stations: 2-32
Cycles/min: up to 100
Torque: up to 60.000 Nm
Design: as housed unit with and without drive
Special feature of INTERMICO rotary index tables: Suitable for heavy loads, high mass moments of inertia and harsh ambient conditions.
Selection:
INTERMICO rotary index table (dimension sheet)

CF 3 - index drive
The MIKSCHCF 3 index drive is based on a complementary disk cam. The input shaft is arranged in parallel to the output shaft. The output shaft always rotates in the opposite direction to the input shaft.
Standard number of stations: 1-8
Cycles/min: up to 1.000
Torque: up to 6.000 Nm
Design: as installation kit or as housed unit with and without drive
Selection:
CF3-stepping motions (DE)

Application example rotary index table
e.g. for:
- driving a plate conveyor
Components are supplied in linear fashion. They are held in a fixture, rotated by 180° and discharged in linear fashion.
An index drive drives a straight-line mechanism wich moves a tool in linear fashion and swivels it, in addition, when passing a crank.
By varying arm lengths and transmissions and angles of input, the coupling curves can be realised within wide limits.
Driven drum has different circumferential speeds on the circumference between the first an 2nd 180°.
Recurring linear movement of a slide is driven via crank and link by means of an index drive.
By combining a 2-station index drive with a downstream thrust crank drive the system generates a straight traversing movement - the forward point passes through an exact straight line with defined end positions.
A straight-line mechanism allows travelling to any position on a straight line from which tools can be removed or inserted. However, a controlled drive is required for this purpose.
The coupling curve can be adjusted within wide limits by changing the lengths of the lever as well as the transmission of the belt stage.
Applications:
For various automation tasks
The task consists of realising exactly defined speed curves during a time progression - e.g. Sheet feeders in printing press.
Slide is moved in linear fashion via crank on index drive. Defined standstills at the reversing points are achieved by the index drive.
Straight-line mechanism for linear strokes
amongst others, looms, tool-changing systems, assembly machines, handling units.
The straight-line mechanism opens and closes a door in a machinery enclosure.
An index drive drives a straight-line mechanism which moves a tool in linear fashion and swivels it, in addition, when passing a crank.
Supplying print products of different formats to further processing, e.g. merging 4-page newspaper sheet with 2-page newspaper sheet and for further processing.
