In order to realize the function of intermittent movement and stop in the transmission of the automation system, the indexing characteristics of the output of the roller gear indexing unit will be fully utilized, and the automation system will complete the production and processing movement through the rotation and stop motion cycle, and there are many types of commonly used drive angles from 90 degrees to 360 degrees. In practical applications, the drive angle is determined according to the running speed, load, etc.
How Does the Drive Angle Affect System Stability?
The size of the indexing angle comes from the number of stations required. For the drive angle of the input shaft, the larger the drive angle, the more stable it is. Especially for high-speed automation systems, the impact force of the input cam at the moving and stopping nodes creates a mechanical shock that causes the entire system driven by the indexing table gearbox to vibrate. This is unavoidable for any mechanical device, but the amplitude is different. The large drive angle increases the contact surface for arc motion during operation.
In actual high-speed operation, too large drive angle can also affect the rotational speed, which requires careful calculations when selecting a rotary indexer to ensure stability and misalignment of the system. The speed of operation is affected. Therefore, whether the roller gear indexing unit will shake during operation is also a common factor that distinguishes the high-quality brand roller indexing unit.
Why Choose Roller Gear Indexing Units Over Other Reducers?
We sometimes find that the roller gear indexing unit of the automation system uses a 360-degree drive angle, in which case a servo motor with higher precision is also used. In fact, the roller gear indexing unit has changed, and it has become an advanced reducer. It can't be said that this design is smarter. On the one hand, it combines the characteristics of servo motors with higher positioning accuracy than cam indexers. On the other hand, it combines the operation of the roller gear indexing unit. stability, why not just use a planetary reducer or a right-angle reducer, because the reducer cannot achieve the advantages of load and torque of the roller gear indexing device. Reducer and roller gear indexing device are different types in the machinery industry, and it should be very wise to be able to comprehensively utilize the advantages of both, but the cost of such a design will be higher. Indexing table gearboxes and common gear motors are sufficient for most industrial automation transmission applications.
