（1） High precision intermittent motion intermittent cam indexing gearbox can achieve accurate intermittent motion. It is divided at fixed angles and time intervals through its internal cam and roller structure. For example, in automated packaging equipment, it can accurately transport and position products at certain angular intervals, with errors controlled within a very small range, usually achieving a division accuracy of about ± 30 seconds, which is difficult for many other transmission mechanisms to achieve. This high precision makes it widely used in production lines that require strict positional accuracy, such as electronic component assembly, pharmaceutical packaging, and other fields.
（2） Compact structure
The structure of cam indexer itself is relatively simple and compact. It integrates the process of converting power input into intermittent output into a smaller device, without the need for large and complex external auxiliary structures. Compared with traditional intermittent motion mechanisms, such as using multiple gear and clutch combinations to achieve intermittent motion, cam indexing gearboxes have significant advantages in space occupation. This is a very important advantage for situations where equipment space is limited, such as small automation equipment, transmission systems inside precision instruments, etc.
（3） High reliability and stability
The internal mechanical structure design makes it highly reliable. Within the normal workload and speed range, the indexing rotary table can operate stably for a long time. Because its movement mainly relies on the cooperation of the cam and roller, after appropriate lubrication and maintenance, its wear is relatively small, which can ensure the stable production of the equipment. For example, in some automated production workshops, equipment using intermittent dividers can operate continuously for months or even years without the need for frequent replacement of critical transmission components.
2、 Disadvantage
（1） Limited torque transmission
The cam indexing rotary table is generally suitable for transmission scenarios with small and medium torque. Compared to some large gear or chain drives, it can transmit relatively less torque. If in heavy machinery applications that require high torque output, such as large ore crushers, the indexing gearbox is likely to fail to meet the requirements of power transmission and is prone to overload damage.
（2） Poor flexibility in speed regulation
The working speed of cam indexing drive is usually determined during the design phase. Although fine adjustments can be made within a certain range, compared to some transmission mechanisms that can flexibly change speed through variable frequency speed regulation, such as belt drive systems directly driven by motors, indexing tables are not flexible enough in speed adjustment. When the production process requires frequent changes in equipment operating speed, the stepper indexing device may not be able to adapt well.
（3） Relatively high cost
Due to the high-precision manufacturing requirements and complex internal structure of fixed station indexing devices, their manufacturing costs are usually higher than some simple transmission mechanisms, such as ordinary pulleys and belt drive combinations. This to some extent limits its application in large-scale, low precision production equipment that is very cost sensitive.
