The utility model has the advantages of compact structure, high efficiency, multiple standard parts, no special processing technique requirement, stable output and big variable-speed range; the automatic tracking speed regulation between zero to the maximum design speed value can be realized.
Description
The utility model relates to a kind of mechanical stepless speed-changing gearing that mainly contains tooth.
Prior mechanical impulse stepless gear box transmission power is little, rotates steadily and speed governing is difficult for quantitative control problem, makes that transmission efficiency is low, noise is high, and minimum speed output can not be zero." internal Link pulsation stepless gear box " that " Link pulsation stepless gear box " that China patent CN1053666A proposes and CN1061472A propose all changes rocking bar into slider-rocker mechanism and it is arranged in the free wheel device, make this speed changer under the situation of contraction structure, be convenient to be provided with a plurality of separated type slotted link mechanisms, with the purpose that realizes that input output are steadily even, have good drive characteristic; Transmission is more, transmission power is little and mechanism is complicated but the separated type bar linkage structure exists all the time.China patent CN2092632U disclose that a kind of structure is simple, gearshift performance is stable and can realize exporting the time minimum speed be zero " speed changer ", its transmission device is formed wobble drive mechanism and driven shaft one-way drive mechanism by eccentric wheel, escapement, connecting rod, and forms speed regulating mechanism in two inter-agency settings by the speed-regulating rack of speed regulating control connecting rod and band handle.This speed changer is in order to reduce the jiggly fluctuation problem of output shaft running clearance and transmission, still need be in input, adorn some groups of but separate type that phase place different identical between output shaft with above-mentioned gear.
The purpose of this utility model is the deficiency at the formed speed changer of above-mentioned separated type composite structure, and proposes a kind ofly have the said structure advantage and for integrated type compact type structure and can further realize mechanical stepless transmission from the motion tracking dynamic speed adjustment.
Its solution is: this mechanical stepless transmission is still by input mechanism, output mechanism and speed control system and casing are formed, its difference is to be on 120 ° of fixedly eccentric bushings that are distributed in input shaft by being fixed on simultaneously with two eccentric adjustment wheels of two flywheels engagement and three movable eccentric bushings that have three connecting plates, form eccentric drive mechanism through the interlock of speed governing pin between eccentric adjustment wheel and the movable eccentric bushing, and directly connect through connecting plate with corresponding Third Mate outer ring arm on the free wheel device, be provided with between the input and output shaft simultaneously its be equipped with input shaft on the clutch blade tooth wheel of differential gear coupling and the speed governing axle of flywheel and be with the man-operated mechanism of shift fork and form all-in-one-piece transmission device.
Further improvement of the utility model is between free wheel device axle and the cover of three on it mono-directional overrun clutch component commonly used 12 (or until 16) rollers to be set respectively.
According to the mechanical stepless transmission that such scheme is made, formed monolithic construction standard piece is many, does not have special processing technology requirement; Output is steadily, slewing range is big, efficient is high, can realize zero between the design maximum tachometer value from the motion tracking speed governing, be particularly suitable for process parameter changeable, require rotating speed to change continuously and the occasion of seeking best effort speed is used.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural drawing of mechanical stepless transmission;
Fig. 2 is the situation plan of this speed changer.
As shown in the figure, this mechanical stepless transmission is made up of input mechanism, output mechanism and speed control system and casing 20, at casing 20 two ends input shaft 16 and free wheel device axle 2 is housed respectively, and speed governing axle 10 and man-operated mechanism 21 are installed between diaxon.Be 120 ° of fixedly eccentric bushings 8 that are evenly distributed on the input shaft 16 being connected with 17,18 and three of differential gears on the input shaft 16; And fixedly be equipped with movable eccentric bushing 5 and eccentric adjustment wheel 7 on the eccentric bushing 8, and make movable eccentric bushing 5 and 7 interlocks of eccentric adjustment wheel by speed governing pin 9, on the movable eccentric bushing 5 connecting plate 4 is housed.Three covers mono-directional overrun clutch component 1 commonly used is housed on free wheel device axle 2, and between the mono-directional overrun clutch component 1 that free wheel device axle 2 and the cover of three on it are used always, 12 (or until 16) rollers 6 is set respectively.Connecting plate 4 on the eccentric drive mechanism that Third Mate outer ring arm 3 on the free wheel device 15 and above-mentioned input system constitute forms kinematic pairs by pivot pin 22.Make its mono-directional overrun clutch 15 partly partly form an all-in-one-piece moving body with eccentric drive mechanism.Assembling a pair of flywheel 11 and 7 engagements of eccentric adjustment wheel on the speed governing axle 10, a pair of clutch blade tooth wheel 12,19 mesh respectively with pair of differential gear 17,18, clutch pawl 13 with about two clutch blade tooths take turns 12,19 and mesh respectively.Clutch pawl 13 usefulness shift forks 14 armrest actuation mechanism 21 move left and right make clutch pawl 13 and 12,19 engagements of clutch blade tooth wheel or disengagement.This clutch blade tooth wheel 12,19 also can be controlled by magnetic clutch.
When eccentric drive mechanism did not need speed governing, clutch pawl 13 was thrown off with 12 engagements of clutch blade tooth wheel and with clutch blade tooth wheel 19, i.e. velocity ratio i=Z18/Z12 * Z11/Z7=1; When eccentric drive mechanism needed speed governing, clutch pawl 13 was thrown off with 19 engagements of clutch blade tooth wheel and with clutch blade tooth wheel 12, i.e. velocity ratio i=Z17/Z19 * Z11/Z7 ≠ 1.
Its working procedure is: when input shaft 16 moved, driving three, to be 120 ° of uniform and offsets be e
1Fixedly eccentric bushing 8 rotate, fixedly the offset on the eccentric bushing 8 is e
2Movable eccentric bushing 5 drive with fixing eccentric bushing 8 by speed governing pin 9 and rotate synchronously.And the motion of speed governing pin 9 is to pass to clutch blade tooth wheel 12 drive clutch pawls 13 by differential gear 18 speed governing axle 10 is rotated, and makes flywheel 11 drive eccentric adjustment wheels 7 that speed governing pin 9 is rotated.When eccentric drive mechanism does not need speed governing, differential gear 17 drives 19 idle running of clutch blade tooth wheel, movable eccentric bushing 5 moves up and down connecting plate 4 with the fixing synchronous rotation of eccentric bushing 8, drive outer ring arm 3 reciprocally swingings through pivot pin 22, make mono-directional overrun clutch component 1 drive free wheel device axle 2 and obtain unidirectional pulsation output power.When eccentric drive mechanism needs speed governing, man-operated mechanism 21 makes shift fork 14 that clutch pawl 13 and clutch blade tooth wheel 12 are thrown off, and take turns 19 with the clutch blade tooth and mesh, make differential gear 18 drive 12 idle running of clutch blade tooth wheel, drive 19 rotations of clutch blade tooth wheel by differential gear 17, and through 10 rotations of clutch pawl 13 drive speed governing axles, drive eccentric adjustment wheel 7 by speed regulation gear 11, asynchronous with the rotating speed of fixing eccentric bushing 8 and realize through speed governing pin 9 drive activity eccentric bushings 5 from the motion tracking speed governing, after best effort speed realizes, after clutch blade tooth wheel 19 is thrown off with clutch pawl 13 immediately automatically with 12 engagements of clutch blade tooth wheel, the state when making speed regulating mechanism revert to eccentric drive mechanism not need speed governing.
