Enforcement of the present utility model in conjunction with the accompanying drawings 1,2,3,4,5,6,7,8,9,10,11, do further narration:
The utility model is to improve and invent at prior art, it is characterized in that speed control system, has adopted bilateral straight-bar open type frame structure, by the little axle 50 of crossbeam, master bracket 40, pair support 48, main control lever shaft 37, pair control lever shaft 47 mutual rigid joint.To be installed in gelled casing 1 movingly, the sliding bearing 38 of case lid 25, become the speed control system (Fig. 6) of bilateral straight-bar open type framework in 46, its advantage is simpler than the bilateral knee closed framework structure (Figure 10) of Japan, lower ending opening is so can utilize under the unrestricted condition in space, the pendulum arm length that adds long arc shape depression bar 29, thereby increased the rotation amplitude of eccentric wheel pendulum housing 28, the output speed upper limit is greatly improved, bilateral straight-bar structure reduces the leverage moment of flexure, for increasing eccentric wheel number of phases M value and simplifying technology, reduce cost, advantage is provided, historical facts or anecdotes is with novel number of phases M value, increase to six phase or bigger values mutually by four of Japan, output speed CLV ceiling limit value and output power have been improved, the utility model is optimized the structure of clutch pendulum housing 2, long-armed plane (Figure 11) by Japan changes the recessed heavy mating face of ultrashort arm type (Fig. 7) into, pendulum arm length R≤0.65D(D is the pendulum housing internal diameter), thickness+cross-tie 21 thickness deviation CLV ceiling limit value+0.1 of recessed heavy face degree of depth T=cross-tie 21, ultrashort arm configuration increases the rotation angle of clutch pendulum housing, improved the output speed upper limit, recessed heavy mating face is submerged within the end face of corresponding clutch pendulum housing 2 each cross-tie 21, and the size after the combination is shortened.Control system has adopted worm and gear structure (Fig. 5); Worm screw 42 connects with handling Worm gear case 36 through worm bearing 43 movingly with hand wheel 41 drive fits.Socket head screw 44 will be handled Worm gear case 36 and be fixed on the case lid 25.Worm gear 35, speed indicator 34 are with main control lever shaft 37 drive fits.By hand wheel 41, worm screw 42, drive worm gear 35, make speed indicator 34, servo-actuated to speed dial 32, shown in the corresponding speed value, finish speed-regulating function.Transmission mechanism of the present utility model is: motor drives input shaft 20 after the startup and eccentric wheel 26 rotate, the eccentric wheel pendulum housing 28 that pine is enclosed within on the eccentric wheel is about radius is done by eccentric distance e around input shaft 20 axis, left and right sides circumference translational motion, because rivet with the other end activity that pine is enclosed within the corresponding arc depression bar 29 on the little axle 50 of crossbeam the lower end of each eccentric wheel pendulum housing 28, so eccentric wheel pendulum housing 28 lower ends are pind down by corresponding arc depression bar 29, when eccentric wheel pendulum housing 28 is done the circumference translational motion with eccentric wheel 26, its lower end has then added an arc swing of following arc depression bar 29 around the little axle 50 of crossbeam, then two kinds of motions are synthetic, make eccentric wheel pendulum housing 28 do eccentric circumference rotation campaign around the axis of input shaft 20.Because eccentric wheel pendulum housing 28 lower ends are with the right-hand member trisome activity riveted joint in groups of an end and the cross-tie 21 of arc depression bar 29,, its corresponding cross-tie 21 does corresponding teeter so being affected, recessed heavy face place, lower end because of the other end of cross-tie 21 and corresponding clutch pendulum housing 2 is movable riveted joint again, so clutch pendulum housing 2 is affected by cross-tie 21, swing synchronously about corresponding axis around output shaft 6 is done, every clutch pendulum housing 2 is that pine is enclosed within on six one group of rollers 3 in the sub-multiple angle faceted pebble of output shaft 6, and each roller 3 is subjected to corresponding pressure spring 4 to press to the direction at angle of wedge tip.When clutch pendulum housing 2 lower ends are affected by cross-tie 21, when swinging to the right, then roller 3 is driven by frictional force (identical with the pressure spring pressure direction) and rolls to angle of wedge tip direction, the pressurized faceted pebble of clutch pendulum housing 2, roller 3 and output shaft 6 is compressed mutually, output shaft 6 is driven and is rotated output power, forms real journey.When otherwise the lower end of clutch pendulum housing 2 is flapped toward left, 3 opposite directions that roll to angle of wedge the top of the horn of roller, pressure spring 4 by compression, 3 of rollers are positioned at the pure end of the angle of wedge, each seal face unclamps by Spielpassung, clutch pendulum housing 2, roller 3, being pressed between the faceted pebble of output shaft 6 are skidded mutually, and power can not be passed to output shaft 6, forms the output of idle running inactivity.Because of input shaft 20 is equipped with M=6 phase eccentric wheel 26, the eccentric direction of each eccentric wheel 26 keeps 60 ° of phase differences during installation.When input shaft 20 under motor drives, then each eccentric wheel acts on successively by phase difference, make half clutch pendulum housing 2 be in real journey the power output state is arranged, other half clutch pendulum housing 2 then is in idle running inactivity output state, under the comprehensive alternating action continuously of each clutch pendulum housing, the result has the clutch pendulum housing 2 of a half to make continuously output power of output shaft 6 per moment, number of phases M is big more, perhaps every phase number N value of roller 3 in groups is big more, power with moment of torsion and the output of rotating speed form is increased, and its mechanical property is also good more.The rotating speed size of output shaft 6 outputs depends on the little axle of crossbeam 50 places
Fixed position on the camber line, this position is controlled by speed control system, during speed governing, rotate hand wheel 41, then worm screw 42 drives worm gear 35, and main control lever shaft 37 is rotated, the little axle 50 of crossbeam that drives bilateral straight-bar open type framework is paid control lever shaft 37 with the open type framework around the master, 47 rotational, the little axle 50 of position limit pin 54 restriction crossbeams makes not surmount
The limit, and the tachometer value that has speed dial 32 and speed indicator 34 indications to be set up after selected speed setting, by lock nut 55 locking speed regulating mechanisms, should be unclamped lock nut 55 during speed governing in advance.When the little axle 50 of crossbeam is set up
The X point time, this point belongs to the amplitude of oscillation maximum point of eccentric wheel pendulum housing 28 rotation campaigns, the tachometer value that the transmission by cross-tie 21 makes output shaft 6 outputs is maximum also, is on the output speed and limits.Maximum output speed value of the present utility model equals the input speed of 1/2.6 motor.Otherwise when the little axle 50 of crossbeam is set up
The Y point time, be little axle 50 of crossbeam and the main control lever shaft 37 of paying, 47 and each axis of riveting point, clutch pendulum housing lower end when being positioned at same horizontal line, then arc depression bar 29 can only be made vertical oscillation up and down around the little axle 50 of crossbeam, make eccentric wheel pendulum housing 28 lower end riveting hinges not produce left and right sides teeter, its horizontal amplitude of oscillation component is zero, and promptly the output speed of output shaft 6 is zero.When the little axle 50 of crossbeam is set up
When going up arbitrary position, then can obtain arbitrary rotating speed output value of speed indicator 34 and speed dial 32 respective value, thereby reach the requirement of stepless speed regulation.
Because the utility model complete machine structure is simple, compact dimensions, so in the relatively little situation of box sizes, power output is bigger, thermal equilibrium condition when satisfying work is provided with enough fin at the tank ends face. Limit value height on the utility model output speed, output speed is bigger than scope, and the mechanical transfer performance is good, and is low in energy consumption. Profile is attractive in appearance; convenient processing and manufacture; common with material, adopt standard component, so its low cost of manufacture as far as possible; adjust as can be known according to sample preparation product; its cost only is about 2/3 of the equal power product cost in market, in the time of also can or shutting down in start, and arbitrarily speed governing; so more be applicable to frequently plant equipment of speed governing, it is a kind of efficient mechanical stepless transmission.
