Shafts TRIZ Cases
- Spindle Motor Bearing Structure for Shaft Wobble Reduction
Distributed shaft support with spaced annular members reduces clamp-hole deformation, improving spindle motor stability, torque, and noise.
- BLDC Motor Bearing Structure Without Spring Preload
A shaft sleeve and adhesive-fixed inner rings replace spring preload to equalize bearing stress, reduce wear, and extend BLDC motor life.
- Indirect Vision Adjustment Unit With Distributed Force Connection
A spring-loaded pressure distribution element spreads load across the adjustment unit, saving space while limiting creep distortion and warping.
- Gas-Bearing Workpiece Support for Uniform Thermal Processing
Gas-bearing pads replace shafts and ball bearings to center and rotate the rotor, reducing contamination and heating non-uniformity.
- Serviceable Bearing Assembly for Grounding Motor Shaft Currents
A conductive sleeve and preload element ground high-frequency motor currents while allowing bearing replacement without rotor-stator disassembly.
- Magnetic Core Bearing Isolation in Electric Machine Shafts
Magnetic cores and EMI shields raise shaft-path impedance to suppress recirculating bearing currents and reduce bearing wear in electric machines.
- Dual-Raceway Front Bearing for Rotor Axial Stability
An X-arranged dual-raceway front bearing limits rotor axial displacement while reducing drag torque in torque transmission.
- Coaxial Motor Shaft Heat Exchanger With Dual Fluid Circuits
A coaxial water-and-oil cooling layout improves rotor shaft heat dissipation while using an oil film to protect motor components from fluid damage.
- Spindle Motor Bearing Structure to Prevent Shaft Wobble
A sleeve and spaced annular bearing members stabilize the spindle motor shaft, preventing clamp-hole deformation, wobble, vibration, and noise.
- Non-Centrosymmetric Stator Core for Higher Maglev Bearing Force
An offset-axis stator core enlarges part of the magnetic path to raise maglev bearing force while lowering working current and loss.
- Elastic Steering Shaft Bearing for Simpler Column Assembly
Plastic-containing bearing rings replace O-rings and simplify steering column assembly while reducing weight and machining steps.
- Rotor Position Sensor Holder With Fastening Ring Bearing Support
A fastening ring anchors the rotor position sensor on the motor shaft while supporting the bearing inner ring, avoiding extra installation tools.
- Adjustable Camera Holder Ring for Windshield Glare Reduction
A movable holder ring lets a vehicle camera shift axially and rotate before locking, helping avoid windshield glare without losing mount stability.
- Steer-By-Wire Sliding Bar Layout Without Pinion Gear Noise
A damper-guided sliding bar replaces the pinion shaft and support yoke to cut steering noise, simplify assembly, and improve durability.
