1. Understanding Flexible Bearings:
LKPB is the most specialized flexible bearings manufacturer，Flexible bearings are mainly used in harmonic reducer or related reduction devices. The harmonic drive consists of four basic components: a wave generator, a flexible wheel, flexible bearing and a rigid wheel, with the flexible bearing being the centerpiece. and the transmission meets the performance requirements of high deceleration ratio through the elastic deformation of bearings.
Flexible bearings, also known as flexible couplings or flexible ball bearings, are mechanical devices designed to transmit torque between two shafts while accommodating misalignments and angular displacements. Unlike rigid couplings, which require precise alignment, flexible bearings excel in compensating for axial, radial, and angular deviations, thereby reducing wear and tear on components.
2. Flexible Bearings Structure：
Flexible bearings for harmonic reducer drive inner hole match with oval shaped cam outer ring; Outer ring which can do elastic deformation to match with flex spline’s opening part inner ring. Flexspline’s opening part outer ring engraved gear engaged with rigid spline teeth. Rigid spline teeth are more than flexspline. Flexspline and rigid spline engaged with each other on long shaft and separated on short shaft. Flexspline bottom is fixed on the output terminal. Rigid bearing is installed on the reducer output terminal and connected with outside.
For low friction torque/high rigidity/good rotation accuracy of bearings, steel balls with small outer diameters are used, and the use of hollow shafts ensures space for light weight and wiring. Thin-walled bearings are highly accurate, very quiet and have a high load carrying capacity. Even with larger shaft diameters and bearing bores, the cross-section remains the same. therefore, these bearings are also known as thin section bearings.
3. Flexible Bearings Features：
In the work of flexible bearings, the inner ring is installed on the elliptical cam, the outer ring is installed on the flexible wheel, and the elastic deformation occurs with the rotation of the cam, which not only bears the cyclic stress load, but also bears the alternating stress load.
- High rigidity: This series bearing have preload
- High load：This series bearing can bear double-direction axial load, radial load and tilting moment
- Small size: This series bearing can save space for machine tools
4. Cross-Industry Applications Of Flexible Bearings：
Manufacturing and Robotics: Flexible bearings play a pivotal role in robotic arms and automated manufacturing equipment. They accommodate movement and vibrations, allowing for precise positioning and reducing stress on delicate components.
Aerospace and Aviation: In aircraft and spacecraft, where weight and precision are critical, flexible bearings enable smooth torque transmission between engines and propellers or turbines. They also mitigate vibrations, ensuring passenger comfort and reducing fatigue on materials.
Automotive Sector: Flexible bearings are used in drivetrain systems, absorbing shocks and vibrations from the road. They contribute to smoother gear shifts and prolonged life of transmission components.
Energy and Wind Turbines: Wind turbines rely on flexible bearings to adapt to changing wind directions. They enhance the efficiency of power generation by allowing the turbine blades to align optimally with the wind.
Medical Equipment: Precision is paramount in medical devices such as surgical robots and imaging equipment. Flexible bearings ensure accurate movement, contributing to successful surgeries and accurate diagnoses.
Renewable Energy: Solar panels use flexible bearings to track the sun’s movement throughout the day, maximizing energy capture. This technology is crucial for efficient solar energy generation.
Marine Industry: Flexible bearings aid in the smooth operation of ship propulsion systems, where vibrations and misalignments are common due to changing water conditions.
