Abstract:
Provided are an oscillation bearing and a wearable device using the bearing. The oscillation bearing comprises an inner ring (101), an outer ring (102), and multiple rolling bodies; multiple first grooves (1011) circumferentially arranged at intervals are formed on the outer circumferential surface of the inner ring (101); multiple second grooves (1021) circumferentially arranged at intervals are formed on the inner circumferential surface of the outer ring (102); each rolling body is provided between the corresponding first groove (1011) and second groove (1021); the rolling bodies, the first grooves (1011), and the second grooves (1021) are configured to limit the inner ring and the outer ring to generate a relative rotation movement and allow the inner ring (101) and the outer ring (102) to generate an axis swinging movement. The use of such an oscillation bearing can improve the energy conversion efficiency of a power generating module of a wearable device.
