摘要： A gear profile for orbital gear transmission is disclosed in which an outer gear (10) and an inner gear (30) are included. At least one of the gears is constrained for orbital motion to impart rotary motion to the other of the gears. The profile of teeth (34) of inner gear (30) is sinusoidal at least in the vicinity of pitch circle (36) of the gear (30) and the pitch circle (36) coincides with the point of inflection (52) of the sinusoidal profile of the teeth (34). The outer gear (10) has a pitch circle (25) and the point of inflection (19) of the inner gear (30) rolls across the point of the profile of teeth (14) of the outer gear (10) where the pitch circle (25) intersects the profile of the teeth (14). Orbital transmission systems are disclosed in which one or the other of the inner gear (10) or outer gear (30) is mounted on an eccentric (63) which is driven by an input shaft (64). An orbit control plate (67) or regressive gear (110) restrains one of the gears (10 or 30) for orbital motion and the plate (67), or regressive gear (110), has a braking member (80) for fixing the plate (67), or regressive gear (110), stationary. In order to place the transmission into neutral, the brake (80) can be released so that the orbit controle plate (67) is able to rotate rather than to constrain the outer gear (10) or inner gear (30) for orbital motion.

摘要： A ratchet mechanism for enabling motion to be transferred in one direction but not in the opposite direction as disclosed which does not require springs. The mechanism includes an engagement member (16, 50, 100, 250, 330) which has teeth for engaging teeth on an outer member (12, 70, 200, 300). The engaging member (16, 50, 100, 250, 330) is mounted on an inner member (30, 80, 220, 320). A drive surface (120, 255, 323) on the engagement member (16, 50, 100, 250, 330) contacts teeth of the outer member (12, 70, 200, 300) when rotated in one direction so as to move the engagement member into position whereby a tooth (18, 110, 258, 335) can engage teeth of the outer member. When rotated in the opposite direction, the engagement member is moved out of engagement with the outer member to enable the ratchet to freewheel. In other arrangements, a cam (34, 321) either alone or in engagement with a drive surface causes engagement or disengagement of the teeth of the engagement member with the outer member.

摘要： A motor for driving a propeller is disclosed which has a drive shaft (10) which is coupleable to a propeller shaft (20) by bevel gears (12 and 14) so as to rotate the shaft (20) to in turn rotate propeller blades P of an outboard motor. The drive shaft (20) has an internal concentric shaft (30) which enables the adjustment of the pitch of the propeller blades P by mounting the propeller blades P for rotation about a pitch axis and coupling the mounting (72') via an integral bevel gear (104) to a bevel gear (102) on the shaft (30). A phase adjustment mechanism (40) is provided for rotating the shaft (30) relative to the shaft (20) to in turn rotate the propeller blades P around the pitch axis to change the pitch of the propeller blades P. The phase adjustment mechanism comprises ring gears (48 and 50), together with planet gears (48) in engagement with a gear on the shaft (30) and planet gears (46) in engagement with a gear (26) on the shaft (20). An anti-backlash mechanism for preventing movement with propeller blades P about the pitch axis due to backlash within the gears of the phase adjuster mechanism (40), includes a screw-threaded section (252) coupled with the shaft (30) and the yoke (270) on the section (252) for movement on the section (252) in the longitudinal direction of the shaft (30). Engagement between the screw-threaded section (252) and the yoke (270) forms a rigid coupling of the shaft (30) to the propeller blades P so that any backlash in the phase adjusting mechanism (40) is not transmitted through the coupling to the propeller blades P.

摘要： A transmission is disclosed which has an input power supply (53, 34, 328) and a plurality of secondary members which are driven by the input power supply. The secondary members can be in the form of pawls (344, 361) or rack and pinion arrangements (54, 56). An infinitely variable gear ratio adjustment mechanism which can adjust the gear ratio between a maximum and minimum ratio is provided and generally comprises a fixed inner eccentric (318) and a movable outer eccentric (320). The outer eccentric (320) can be moved to adjust the eccentricity of the eccentrics to thereby set the gear ratio to any ratio between the minimum and maximum. The pawls (344, 361) or racks and pinions (54, 56) are arranged on the eccentrics (318, 320) and are driven by the input for only part of each revolution of the input other than when the gear ratio is set as 1:1. A mechanism for ensuring that the load applied to the secondary members is distributed between at least two of the secondary members at any one time is provided and comprises a lever arrangement (106), a floating ring arrangement (76) or a resilient biasing rubber ring (380, 382).

摘要： A transmission has a gear system (34) which may be in the form of an orbit system (32, 35) or a planetary orbital spur system. The gear systems include a control gear (32) which is controlled to determine the drive ratio of the transmission. The control gear is controlled by a mommentum control which includes a disc (23) and a slide (25) which carries a magnet (30) for selectively allowing or preventing rotation of the disc (23) to in turn change the speed of rotation of the control gear (32). Alternatively the momentum control can be formed from moveable masses which move radially outwardly relative to the control shaft to change the speed of rotation of the control gear.

摘要： The phase control mechanism includes first gears (3,4) coupled to the output shafts (2,1a) which are to be phase controlled. A Transfer gear (5) is provided for rotation or operation independent of the input and is coupled to the first gears (3,4) to allow rotary motion to be transferred between the first gear members (3,4) and a phase adjuster (10,17) causes the first gears (3,4) to advance on regress relative to one another to change the phase relationship between the outputs.

摘要： A multiple speed orbital transmission is disclosed which has orbit gear pairs (10-30, 220-230 and 220'-230'). One of the pairs (230-220 or 230'-220') form an orbit control by fixing stationary or otherwise controlling the outer gear (230 or 230') so as to cause the gear (30) to execute an orbit to drive gear (10) to provide output rotary power. A brake (80 or 80') is provided for fixing the gear (230 or 230'). The gear pairs have different gear ratios between them so that by selecting and braking one of the gears (230 or 230') so the gear pair to which that gear belongs controls orbital motion of the orbit gear (30) will set the drive ratio of the transmission. Thus, by selectively causing the brake (80) to brake one of the gears (230 or 230') the drive ratio can be changed.
