Harmonic Drive Etching Machining Harmonic Gear CSF-17-100-2UH

Abstract 

The controller's control over a certain transmission results in an adjustable output speed range of 1 to 540 rpm. The load variation ranges from 0 to 20 Nm. Within the entire speed range, the speed fluctuation is within ±2 rpm. The Harmonic Drive Flexible Transmission Harmonic Gear CSF-17-100-2UH requires high speed control accuracy, achieving up to 1% precision. It should be noted that speed control operates under the condition that the load torque does not exceed the maximum output torque provided by the prime mover. It becomes ineffective during overload conditions. The selection of control accuracy should meet user requirements without being excessively high to avoid affecting the lifespan of the executing motor.

The rigid fixed-axis infinitely variable transmission consists of rigid transmission components. When the Harmonic Drive Flexible Transmission Harmonic Gear CSF-17-100-2UH is not adjusting speed, the rotating axis positions of each transmission component remain fixed, but they vary during speed adjustment. It features a simple structure and diverse forms. It is divided into two categories: with and without intermediate rollers. The former has a larger speed adjustment ratio (Rb = 1 to 21), while the latter has Rb = 6. To improve the power-to-volume ratio, a multi-intermediate transmission method is commonly used. For variable speed devices that require both acceleration and deceleration, two sets of pressurization devices are generally used. The contact area of transmission components can be designed as either initial point or line contact structures. The former has slightly lower load capacity but less relative sliding, compensating for deformation due to force and errors in processing and assembly. The latter has higher load capacity but requires higher manufacturing and assembly precision.

During speed adjustment, due to the significant axial displacement of the speed transmission components, only columnar helical springs and large-angle cylindrical end cam pressurization devices can be used.
