Abstract
The invention discloses a pneumatic bidirectional output shaft based on a magnetic-air hybrid spherical bearing, and aims to overcome the defect that severe heat radiation exists when a motor is adopted as a built-in driver of a bidirectional output spindle. The pneumatic bidirectional output shaft comprises permanent magnets, a spherical bearing spindle, impellers, permanent magnet seats, air guiding shells and spindle supporting parts, wherein compressed air is injected into the inner and outer cavities of the air guiding shells through first air inlets and second air inlets respectively; the compressed air injected into the inner cavities of the air guiding shells enters spherical bearing supporting holes through supporting part air inlet holes of the spindle supporting parts; the compressed air injected into the outer cavities of the air guiding shells drives the impellers to rotate, the rotating impellers drive the spherical bearing spindle to move, and then the compressed air is exhausted through first interstitial holes, second interstitial holes and axial air outlet holes; and through radial air outlet holes of isolating rings, too high internal pressure and turbulent air flow are prevented. According to the pneumatic bidirectional output shaft disclosed by the invention, the impellers are adopted as power sources and the problem about heat radiation of the built-in driver is solved.
