Parallel dial Index drives were intended in the Drive is intended to combine in parallel the turret of the output shaft with the parallel cam of the input shaft. One of the plate cam units is a constraint cam and a conjugate cam that moves intermittently to transmit the roller of two cams.

Along the cam curve, the contour of the cam consists of the mount shaped segment and the round of the dwell section. Two cameras are joined in a kind of gear form differently. Rotation starts when the roller runs over the top side.

Parallel Dial Index Drives' work is based on a strict and complex system, mostly derived from the synergy between the parallel drive and the indexing control technology.

The whole device runs on the motor, which generates great speed rotational torque during start-up. Transmission components including belts, chains or gears help to transfer this starting power to the indexing disk. Consider gear transmission: every rotation of the active gear precisely drives the slave gear, which drives the indexing disk to operate. The active gear on the motor shaft and the slave gear on the indexing disk mesh with each other.

These transmission components should not only guarantee the smoothness of power transfer, lower the jams or impacts caused by inadequate transmission, but also have strong wear resistance and high strength to adapt to long hours, high load operating situations. Their design is rather vital. To guarantee the stability and accuracy of power transmission, for instance, the use of high-precision helical cylindrical gears, their great degree of overlap, smooth transmission characteristics, may efficiently lower the transmission process of noise and vibration.

Accurate control of the stopping and placing of the indexing disk falls mostly on the indexing mechanism as it rotates the disk. Usually, cams, grooved wheels, indexing pins and so on make up the indexing mechanism. Consider the groove wheel mechanism: the cylindrical pin on the active dial enters the radial groove of the groove wheel to drive the groove wheel to rotate at a designated angle; once the cylindrical pin leaves the radial groove, the groove wheel stops rotating, so realizing the intermittent rotation of the indexing dial depending on the preset angle.

The particular manufacturing needs determine the preset indexing angle; hence, the accuracy of this angle directly influences the processing and assembly quality of the product.

The exact collaboration between the sensor and the control system determines the full working process as inseparable. Real-time position of the indexing disk, speed and movement status, other parameter monitoring via sensors. For instance, accurate feedback indexing disk position information by means of photoelectric encoder, which may translate the angular displacement of the indexing disk into digital signals.

Real-time transmission of these signals to the control system allows the control system to precisely adjust motor rotation speed and steering in response to established program and parameters. Once the position deviation of the indexing disk is found, the control system will rapidly change the operating state of the motor to guarantee that the indexing disk stops at the predefined location exactly and faithfully, thereby implementing high-precision indexing and positioning.

Parallel Dial Index Drives may actualize precise and efficient indexing motion to satisfy the demands of many industrial production for high-precision and high-stability motion control by means of close cooperation of power transmission, indexing control, and signal feedback adjustment.

One major plus is its great precision. Advanced transmission and control technology allows Parallel Dial Index Drives to attain highly exact indexing placement and the indexing precision may approach ± 0.001 degrees or even higher. For various industrial operations, such optical instrument manufacture, electronic chip manufacture and so on, this is of enormous relevance as it calls for extremely high accuracy.

Operating efficiency of parallel dial index drives is quite high. Its parallel construction helps to increase the power transmission efficiency by smoothing out the transmission process and so lowering energy loss. Simultaneously, the quick indexing action and steady operating performance shorten the production cycle considerably and raise production efficiency.

One should also highlight its dependability and stability. The gadget decreases equipment failure and maintenance cost by using high-quality materials and exact production technique, which guarantees stable and dependable operation even under long-time and high-intensity working environment.
