In the automatic transmission machinery, the six types of indexer commonly used are flange type indexer, mandrel type indexer, hollow type indexer, platform desktop type indexer, ultra-thin platform type indexer and flat conjugate type indexer. So what is the main difference in the appearance of these six models?
globoidal cam indexer
Flange type indexer, as the name implies, the flange type mainly describes the form of the indexer output shaft end, and the short shaft with the protruding platform. It is mostly used for the intermittent transmission of the disc type indexer multi-station, and the short shaft can be directly worn. Through the disc hole, the flange can be used in the same way as the flange. The fixing screw can be used to ensure the accuracy of the axial rotation and ensure the connection between the disc and the indexer.
The mandrel type indexer means that the output end of the cam indexer is in the form of a long axis. The long axis type is characterized in that it is easy to generate axial runout during the whole system operation, and is mostly used for gears, shafts or For the shaft, during the installation process, special attention should be paid to the aperture tolerance (+0.015/-0). In the case of use, belt drive, gear drive and gapless drive are combined.
The hollow type indexer is similar to the flange type except that the output of the flange is not a short axis but is outputted in the form of a hole. For a special demand, there are many components of the automatic equipment control system. Water, electricity, gas pipes, etc. can be taken from the holes of the hollow structure.
 The DT platform desktop indexer is different from the others in that it has a larger outer structure than a flange type indexer. The drive can withstand large axial loads and vertical radial pressure, and has a convex fixing at the output end. The disk surface and the large-aperture hollow shaft can be equipped with dynamic and static automatic peripheral equipment, and the electric, oil and gas pipelines of the power source can be arranged in the hollow holes. Due to its own characteristics, this model is widely used in heavy-duty automated operation systems.
The sizing design of the ultra-thin platform type indexer is similar to that of the platform desktop type, but its overall component has a wide planar span, but the height is low, and the overall appearance is relatively compact, so its accuracy is higher than that of the platform desktop. The indexer can withstand large axial loads and vertical radial pressure during driving operation, and the large hollow structure can pass through the pipeline. At the same time, the large flange output surface makes the driven body run more stably.
The flat type indexer has two plate-shaped cams fixed to the input shaft, and can be driven by the cam-driven roller turret shaft. The mechanism with parallel common rail cam is suitable for belt conveyor with large pitch. The processing of the pipeline needs the function of stop and stop. The flat type indexer with special function can be used for intermittent indexing, from short to long. The function can be implemented at any time. In the flat type operation, it is also possible to add more than three plate cams to the indexer use system that requires an increased rhythm.
