Cam Indexer

Being one of the earliest professional Cam Indexer manufacturer in china mainland, G+ has been the leading brand of Cam Indexing Drive in china for more than ten years. G+ cam indexers are manufactured and assembled in G+ Shenzhen Factory, utilizing the most precise and state-of-art technologies. Each G+ globoidal cam indexer promises quality, repeatability and accuracy. Cam indexers are suitable for a wide range of applications including electronic components assembly machines, food packaging machines and quality inspection machines. The G+ range of cam indexers are trusted by well-known system integrators and reputable factories from Huawei, Foxconn, Han’s Laser, Johnson Electric and etc in China.

1. What is the Cam Indexer?

Cam Indexer, also known as cam splitter, cam indexing drive, cam indexing positioner, or globoidal cam indexer, is a mechanism for intermittent motion, which is featured with large transmission torque, high indexing accuracy, stable operation, compact structure, self-locking during positioning, small size, low noise, high speed performance and long life.

2. What is the Product Features of G+ Cam Indexing Drive?

G+ cam indexing drive use rolling contact for smooth indexing and longer life. It is an ideal product to replace traditional mechanisms such as groove wheel mechanism, ratchet mechanism, incomplete gear mechanism and pneumatic control mechanism.

G+ preload provides rigidity and allows for zero-backlash, providing high accuracy and extremely fast settling time. Robust cam and turret design, with the industry’s largest diameter matched-set needle roller cam followers, allow for higher load capacity. These features make G+ cam indexer positioners the choice of engineers nationwide.

• Precision Driving Mechanism

At the moment of indexing or stop, the follower is secured in place within the prescribed position, thereby eliminating the need for any locking elements.

• High Speed Performance

Backlash is completely eliminated by applying a preload to the tapered-rib of the precision machined cam and the cam follower, resulting in reliable high speed operation. Fully controlled acceleration minimizes shock due to load or vibration.

• Smooth Transmission

As the turret is designed to rotate continuously in any position (regardless of angle, speed and/or acceleration) the driving transmission is smooth and free of vibration and noise.

• Simple Mechanism

Composed of only a cam and turret; no unnecessary parts, while providing any intermittent motion needed.

• High Indexing Accuracy

G+’s specially designed cam follower within the index drive ensures heavy load capability while maintaining high indexing accuracy and high torque. The indexing accuracy of the standard models is ±30 seconds. However, models providing higher indexing accuracy are available upon request.

• Motion Curves

Modified trapezoid curve (for high speed and low loading), modified sine curve (for middle/high speed and middle loading), modified constant velocity curve (for low speed and heavy load) are available corresponding to required applications.

3. Mechanism and Structure of GIGAGER Cam Indexer

G+ Cam Index Drives are designed that the globoidal cam installed in the input shaft mates with the turret fixed to the output shaft as shown in above picture. The cam follower which is radially embedded in the circumferential surface of the turret comes into linear contact with the tapered rib of the cam to their respective wall surfaces.

When the input shaft rotates, the cam follower rotates the output turret following a given displacement curve while simultaneously rolling along the wall surface of the rib. In the area where the rib is parallel with the end surface of the cam, that is, in the static range, the follower turns on its axis, but the turret itself does not rotate.

The tapered rib always comes into contact with two or three cam followers so that the revolution of the input shaft can be evenly transmitted to the output shaft.

If there is backlash between the cam surface of the tapered rib and cam follower may damage the cam indexer.

This backlash can be completely removed by rotating the eccentric flange supporting the input shaft and shortening the distance between the input shaft and the output shaft. The rigidity of the indexing drive can be enhanced by adjusting the preload appropriately within the elastic region of the cam follower and cam.

Its structure and function are the most outstanding features of this combination of globoidal cam and cam follower, making it capable of high speed operation.

4. How Many Model Are Available?

G+ Cam Index Drives are classified into the following three types with the configurations of the output portions: Shaft Model, Flange Model, Flange Shaft Model, Table Model, Ultrathin Table Model, Sway Model, Paradex Model, Lifting Mechanism Custom Model, Analog Five-axis Coupling Unit, Triple Shaft Cam Indexer.

We also support special dimension custom service and special cam production.
