Product Details
The Harmonic Reducer is comprised of a Harmonic Generator, Flexspline, Rigid Spline, and a Rigid Bearing (Crossed 14) and Flexible Bearing (H-Section Deep Groove Ball Bearing). The Flexible Bearing's inner hole aligns with the outer ring of the cam, allowing for elastic deformation to match the Flexspline's opening part inner ring. The outer ring of the flexspline's opening part is engaged with the teeth of the rigid spline. The number of teeth on the rigid spline is greater than that on the flexspline. The flexspline and rigid spline are engaged with each other on the long shaft and separated on the short shaft. The flexspline bottom is fixed on the output terminal, while the rigid bearing is installed on the reducer output terminal and connected to the outside.
Harmonic reducers are typically utilized in manufacturing sectors such as robotics, machine tools, and aerospace, where high precision, rigidity, and load capacity are essential. Therefore, high standards are required for the machining precision of harmonic reducer parts, the precision of the mounting, and the precision of the bearings. In the case of rigid bearings, the most important factors are the rigidity, reliability, and rotation precision of the bearing. Rigid bearings usually undergo a preload process before leaving the factory to guarantee that the bearing has sufficient rigidity. The maximum radial deformation is of particular importance for flexible bearings.
Features of Rotary Table Bearings
1. High Load-Bearing Capability: Harmonic reducer bearings handle multiple load types simultaneously, allowing for high torque transmission in compact systems.
2. Minimal Backlash: Due to the unique harmonic drive mechanics and high-precision bearings, backlash is virtually eliminated, which is crucial for applications requiring precise positioning.
3. Compact and Lightweight: Harmonic reducer bearings are designed to support a high reduction ratio in a compact, lightweight package. This helps in reducing the footprint of the machinery while still delivering high torque.
4. High Stiffness and Accuracy: Bearings used in harmonic drives have high stiffness, allowing for accurate, smooth rotation, even under heavy loads. This enhances the reliability and durability of the overall drive system.
5. Reduced Friction and Heat Generation: Properly designed bearings minimize friction, which is critical in high-speed applications to reduce wear and prevent excessive heat buildup.
