Energy harvesting device converting multiaxial translational and rotational motion to unidirectional rotational motion

An energy harvesting device for harvesting energy of a wave, motion of the wave resulting in pitch, sway, yaw, surge, roll, and heave movement, the energy harvesting device comprising:

• a housing assembly having an upper housing (M2a, M2b, M2c), a middle housing (M2d), and a lower housing (M2e);
• an input shaft (S1) being configured to move in response to the movement of the wave;
• the input shaft (S1) being rotatably coupled to a second shaft (S2a, S2b, S2c) that is rigidly coupled to a fourth bevel gear (BG4) that meshes with a fifth bevel gear (BG5), a third spur gear (BG3) is rigidly attached to the fifth bevel gear (BG5) along a common axis and freely mounted on a fourth shaft (S4), a third shaft (S3) freely supports the fourth shaft (S4), the middle housing (M2d) freely supports the third shaft (S3), the third spur gear (BG3) meshes with the fourth spur gear (BG4), a sixth shaft (S6) is supported by the middle housing (M2d) and rigidly carries a fourth spur gear (SG4), a seventh spur gear (SG7), and a tenth spur gear (S10), the seventh spur gear (SG7) operably meshes with an eighth spur gear (SG8) which meshes with a ninth spur gear (SG9), the tenth spur gear (SG10) operably meshes with an eleventh spur gear (SG11), an output shaft (S8) supports the ninth spur gear (SG9) and the eleventh spur gear (SG11) via a first one way bearing (OWB1) and a second one way bearing (OWB2), the lower housing (M2e) freely supports the output shaft (S8);
• the second shaft (S2a, S2b, S2c) being rotatably coupled to the upper housing (M2a, M2b, M2c) which is rigidly coupled to the third shaft (S3), the middle housing (M2d) freely supports the third shaft (S3), the third shaft (S3) rigidly carries a fifth spur gear (SG5) that meshes with a sixth spur gear (SG6), a fifth shaft (S5) supported by the middle housing (M2d) rigidly carries the sixth spur gear (SG6), a seventeenth spur gear (SG17) and a twentieth spur gear (SG20), the seventeenth spur gear (SG17) operably meshes with an eighteenth spur gear (SG18) that meshes with a nineteenth spur gear (SG19), the twentieth spur gear (SG20) operably meshes with a twenty first spur gear (SG21), the output shaft (S8) supports the nineteenth spur gear (SG19) and the twenty first spur gear (SG21) via a third one way bearing (OWB3) and a fourth one way bearing (OWB4);
• and
• the input shaft (S1) is further rigidly coupled to a first bevel gear (BG1) that meshes with a second bevel gear (BG2) that in turn meshes with the third bevel gear (BG3), the fourth shaft (S4) is rigidly coupled to the third bevel gear (BG3) and a first spur gear (SG1), the fourth shaft (S4) is freely mounted on the third shaft (S3), the first spur gear (SG1) meshes with a second spur gear (SG2), a seventh shaft (S7) supported by the middle housing (M2d) rigidly carries the second spur gear (SG2), a twenty second spur gear (SG22), and a twenty fifth spur gear (SG25), the twenty second spur gear (SG22) operably meshes with a twenty third spur gear (SG23) which meshes with a twenty fourth spur gear (SG24), the twenty fifth spur gear (SG25) operably meshes with a twenty sixth spur gear (SG26), the output shaft (S8) supports the twenty fourth spur gear (SG24) and the twenty sixth spur gear (SG26) via a fifth one way bearing (OWB5) and a sixth one way bearing (OWB6),
• wherein multiaxial translational and rotational motion of the input shaft (S1) and the housing assembly is converted to unidirectional rotational motion of the output shaft (S8).
