DF Cam Indexer is a flange type cam splitter designed for high-precision, high rigidity, medium to low-speed heavy-duty applications. It adopts a cylindrical cam structure and is suitable for industrial scenarios that require precise indexing and high torque transmission.
The output shaft of DF Cam Indexer is designed with a flange, featuring a flange center, screw holes on the disc surface, and locating pin holes. The fixing surface is wide, making the connection more secure and stable. This structure enables it to withstand large vertical radial or axial forces and has heavy load characteristics.
DF Cam Indexer has a large transmission torque and can adapt to high load working scenarios. At the same time, it has the advantages of small size, low noise, long service life, and no maintenance, and has high indexing accuracy, stable operation, and self-locking during positioning, which can meet the high-precision requirements of various automation equipment.
The common models of DF Cam Indexer include 45DF, 60DF, 70DF, 80DF, 110DF, 140DF, 180DF, 250DF, etc. Different models have differences in size, load-bearing capacity, and torque output, which can meet the needs of different application scenarios.

What is the working principle and Typical applications of DF Cam Indexer?
The working principle of DF Cam Indexer is similar to other cam dividers. It relies on the seamless fit between the cam and the needle roller bearing to move according to the predetermined cam curve. Input continuous rotational drive, drive the needle roller bearing through the cam profile, and achieve intermittent rotational motion of the output shaft, which can output precise indexing motion.
Widely used in fields such as pharmaceutical machinery, printing machinery, food packaging machinery, glass machinery, ceramic machinery, machine tool machining centers, etc., it is mainly used to drive various disc processing machinery, automatic intermittent drive components, and drive discs to achieve high-precision intermittent indexing motion.
|
Working Principle |
Dividing stage |
The input shaft rotates, and the cam pushes the roller to drive the output shaft to rotate a preset angle (such as 90 °). |
|
Pause stage |
The cam enters the holding section, the output shaft is locked, and processing or assembly operations are carried out. |
|
|
Repeat cycle |
Complete the intermittent motion of "rotation pause", with a division accuracy of ± 30 arcsec. |
|
|
Typical applications |
Fourth axis of machine tool |
Heavy duty workpiece indexing milling (such as automotive wheel hub machining). |
|
Stamping automation |
intermittent feeding and positioning of metal sheets. |
|
|
Assembly line turntable |
Multi station assembly of engine components. |
|
|
Testing equipment |
Rotating scanning of large-sized workpieces. |
What are the key selection points?
1).Load torque: The static/dynamic load of the workpiece and fixture needs to be calculated.
2).Dividing angle: commonly 90 °, 120 °, 180 ° (customizable non-standard angle).
3).Accuracy requirements: Standard type ± 30 arcsec, high-precision type ± 15 arcsec.
4).Protection level: IP54 (basic dustproof) or IP67 (harsh environment).
How are the Maintenance and lifespan of DF Cam Indexer?
1).Lubrication cycle: Replace lubricating grease every 5000 hours (shortened to 2000 hours under heavy load conditions).
2).Wear inspection: Regularly monitor the surface of the cam and roller for pitting corrosion.
3).Lifespan : Under normal maintenance, it can reach over 100 million divisions.
DF Cam Indexer is a classic solution in the field of heavy-duty indexing, which performs excellently in low-speed and high load scenarios with cylindrical cam+dual support structure. When selecting, priority should be given to matching load torque and division accuracy, and reliable brands should be selected to ensure long-term stability. Suitable for applications with strict rigidity requirements such as machine tools, stamping, and heavy-duty assembly.
