Description

The unidirectional output accelerator of two-way input

Technical field

No matter a kind of input is postive direction rotation or opposite spin, output is a fixing direction rotation, and rotation simultaneously is accelerated.Belong to field of power machinery.

Background technique

The present invention satisfies the special requirement of some equipment, i.e. the rotation of both direction is converted to the acceleration rotation of a direction, is the ideal equipment of wave or tidal energy utilization.

People are when utilizing the energy, because the narrow limitation of traditional energy, make people continually develop and utilize the new energy, for example: exploitation solar energy, utilize wave or tide energy etc. on a large scale, some field needs some special machinery, and the present invention is exactly the moment of torsion that wherein torque axis repeatedly can be changed into a direction, realizes utilizing wave and tidal energy.There was the researcher to develop this series products in the past, as: patent of invention number be: 03240677.0 coaxial two-direction is imported the utility application of unidirectional output speed increaser, it has utilized Der Grundsatz der Maschinen successfully to realize the unification of moment of torsion sense of rotation, but it does not have extensive the utilization is because its shortcoming, in realizing the unified process of sense of rotation, when idle pulley is changed in sense of rotation, its sense of rotation also changes, back and forth rotation is less in the angle that folk prescription makes progress when input end, and during long-time running, it is not full revolution that idle pulley rotates, and the concentrated wear meeting reduces its life-span, has directly caused it not turn round for a long time.The invention solves this problem, no matter and realized the rotation angle size of rotation input end of the output rotating part of whole device, the rotation of output terminal all is to rotate to a direction always, become the rotation of circumference to make mechanical wear average, can large-scale utilization in the development and use of wave or tidal energy, and the moment of torsion of this device is very flexible on the way of output.Accelerating unit adopts the form of planetary gear set, makes whole device compact in design, and volume is little, takes up an area of for a short time, and driving torque is big, characteristics such as efficient height.

Summary of the invention

This device mainly is made up of two cover overrunning clutchs, differential mechanism, axle, bearing, planetary gear set etc.Differential mechanism comprises that the transmission bevel gear on the both sides of relaying bevel reduction gear set that intermediate circumference distributes and its engagement forms, and we utilize the effect of the opposite moment of torsion of the transmission of differential mechanism here.Overrunning clutch mainly is made up of input end, output terminal and middle equipment.

Two cover overrunning clutch intermediate arrangement differential mechanisms, the transmission bevel gear on differential mechanism both sides is fixed with the output terminal of the overrunning clutch that closes on respectively, and the output terminals of two cover overrunning clutchs are fixed together.The input end that is fixed together when two cover overrunning clutchs rotates to a direction, because two cover overrunning clutch working staties are opposite, have only the output terminal of a cover overrunning clutch that the definite output of sense of rotation is arranged, another set of is freely to dally, when two cover overrunning clutch input end sense of rotation change, then the overrunning clutch of previous work converts to freely and dallies, and another set of overrunning clutch is started working, and the sense of rotation of its output terminal changes through differential mechanism relaying bevel reduction gear set makes its output consistent with the outbound course of the overrunning clutch of previous work.

Gear on the relaying bevel reduction gear set of the output terminal of every cover overrunning clutch and differential mechanism is separately regularly towards a direction rotation, so they all can be used as the moment of torsion output terminal.

Planetary gear set is by the internal tooth wheel for inputting, planetary pinion, the planetary pinion bracing strut, be accelerated gear, compositions such as accelerating gear, middle circle distribution several (choosing) planetary pinion according to actual conditions, the sun gear engagement at each planetary pinion while and internal tooth wheel for inputting and center, each planetary pinion is fixed on the planetary pinion bracing strut, and gear shaft support opposite side is fixed with and is accelerated gear, and accelerating gear simultaneously and internal tooth wheel for inputting and be accelerated gear engagement, accelerating gear axle and immovable point are fixed, when the internal tooth wheel for inputting fix direction when rotating and its planet gear meshed and accelerating gear rotate simultaneously, the accelerating gear engagement is accelerated gear, driving the planetary pinion bracing strut rotates, make planetary pinion quicken rotation, the sun gear at engagement center rotates, and drives main axis rotation.Choosing of the speed-up ratio of planetary gear set is relevant with the gear diameter in each planetary gear set, can choose as required.

Sense of rotation by the rotation that is transformed into a direction after, the internal tooth wheel for inputting concentric of device output terminal that sense of rotation is fixed and planetary gear set is fixed, and realizes that sense of rotation is transformed into unidirectional and is quickened by planetary gear set by two-way.

Description of drawings: Fig. 1 and Fig. 2 are respectively structural drawing of the present invention

Fig. 1 is the structural drawing that the output terminal of one of them overrunning clutch is connected with planetary pinion, is made up of following parts: input torque end 1, output terminal 2, transmit bevel gear 3A, transmit bevel gear 3B, relaying bevel gear 4, bearing 5, support 6, output terminal 7, fixing bolt 8, cross the axle collar 9, internal tooth wheel for inputting 10, planetary pinion 11, bearing 12, accelerating gear 13, planetary pinion bracing strut 14, bearing 15, stationary axle 16, be accelerated gear 17, cross the axle collar 18, rigid bearing 19, main shaft 20, sun gear 21, input end 22, input end 23, connecting sleeve central siphon 24.Wherein input end 22 and output terminal 2 are formed a cover overrunning clutch; Input end 23 and output terminal 7 are formed a cover overrunning clutch, and two cover overrunning clutch operative orientations are opposite.Transmission bevel gear 3A, relaying umbrella shape tooth 4, bearing 5, support 6, transmission bevel gear 3B constitute differential mechanism jointly.Internal tooth wheel for inputting 10, planetary pinion 11, accelerating gear 13, be accelerated gear 17, cross the axle collar 18, planetary pinion bracing strut 14, sun gear 21, axle 20 are common constitutes planetary gear set.The input end 22 of input torque end 1 and two cover overrunning clutchs is fixed together by connecting sleeve central siphon 24 with input end 23; Transmitting bevel gear 3A and output terminal 2 is fixed together; Transmitting bevel gear 3B and output terminal 7 is fixed together.Its working procedure is as follows: when input torque end 1 rotates, drive a cover overrunning clutch job, another set of idle running, output terminal 2 and output terminal 7 are by the engagement driving of relaying bevel reduction gear set, direction of rotation, when the sense of rotation of input torque end 1 changes, the overrunning clutch idle running of previous work, the overrunning clutch of previous idle running is started working, and keeps output terminal 2 and output terminal 7 and relaying bevel gear 4 forever to oneself fixing direction rotation.Output terminal 7 is fixed together by fixing bolt 8 and internal tooth wheel for inputting 10, because the sense of rotation of output terminal 7 is fixed, be that turning to of internal tooth wheel for inputting 10 is fixing, it is meshing planetary gear 11 and accelerating gear 13 rotations simultaneously, accelerating gear 13 engagements are accelerated gear 17 and rotate, driving planetary pinion bracing strut 14 rotates, because planetary pinion 11 is consistent with accelerating gear 13 sense of rotation, promptly quickened the rotational velocity of planetary pinion 11, the sun gear 21 of while and planetary pinion 11 engagements is accelerated rotation, and drive and sun gear 21 fixing main shafts 20 quicken rotation.
