, specifically as shown in Fig. 4～Fig. 5, the structure of the second non-circular gear is concrete such as Fig. 6～Fig. 7 for the structure of the first non-circular gear
It is shown.
On the premise of function is realized, the design of whole machinery being made as far as possible, being simple to manufacture easy, structure arrangement is more tight
Gather.Frequency control motor 1 can realize large-scale stepless speed governing, with adapt to work implement 9 friction speed require and
Improve the dynamicss when machine opens braking；Rubbercushioned sleeve bearing coupling 2 is immunity shaft coupling, can be subtracted with minimally
Impact of few operating mechanism to frequency control motor 1；Brake 3 adopts electromagnetic hydraulic pressure push rod block brake, both can ensure that
It is reliable to brake, braking impact can be reduced again.4 essence of non-circular gear dispenser belongs to planetary reducer, between realizing
Have a rest motion, first order transmission adopts non-circular gear drive, and the second non-circular gear 424 is used as the first sun gear fixed with frame
(centre wheel), the first non-circular gear 407 is used as planetary gear；The second level is driven using spur gear wheel, planetary cylindrical spur gear 412
Used as planetary gear, the roller gear on gear shaft 421 is used as rotatable second sun gear (centre wheel).Power is from planet carrier
405 inputs, export from rotatable second sun gear.
The operation principle of apparatus of the present invention：When brake 3 is in declutches state, frequency control motor 1 is powered and operates, and moves
Power reaches the input shaft 422 of non-circular gear dispenser 4 through shaft coupling 2, brake 3 from 1 on of frequency control motor, defeated
Entering axle 422 drives planet carrier 405 to rotate, and the rotation of planet carrier 405 causes the first non-circular gear 407 and planetary cylindrical spur gear
412 compound motion, the compound motion have two components, and one-component is respectively around fixed first sun gear (the
The revolution 424) with rotatable second sun gear (roller gear on gear shaft 421) of two non-circular gears, second component point
Not Wei the two around the rotation of planet axis 408, finally show motion for the motion of corresponding Vector modulation, the resultant motion passes through
Second sun gear (roller gear on gear shaft 421) output is to crank disc 5,5 drivening rod of crank disc, 8 reciprocally swinging, connecting rod 8
The performs device that pushes the work forward 9 does reciprocating linear motion.In this process, due to having the first non-circular gear in dispenser train
407 and second non-circular gear 424 presence, so work implement 9 movement an impulse stroke in, it may appear that the sun
Wheel (roller gear on gear shaft 421) is output as zero one or several time periods, and now work implement 9 is correspondingly
In resting state.Therefore, in a cycle of the work of work implement 9, step reciprocating linear fortune can be completed
It is dynamic.Simultaneously as the arc groove of adjustable crank radius on crank disc 5, is provided with, by adjusting position of the regulating bolt 7 in arc groove
Put, the throw of different radii size within the specific limits, can be obtained, now the shift motion of work implement 9
Size can also occur correspondingly to change.When 3 band-type brake of brake, frequency control motor 1 slows down until shut down, whole device
Quit work.
The design procedure of apparatus of the present invention：1. according to computational load power primary election frequency control motor 1；2. will according to design
The time dependent function of resultant gear ratio is determined at the beginning of the parameters such as the operating rate asked, each mobile working stroke idle hours；③
The sub-transmission ratio function of non-circular gear engaged transmission is determined according to gear ratio distribution principle；4. first is designed by sub-transmission ratio function
The pitch curve of non-circular gear 407 and the second non-circular gear 424；5. complete each parts design of dispenser；6. joined by impulse stroke
Number and other job requirements design range-adjustable crank block device；7. 1 starting time of frequency control motor, heating, mistake are carried out
Carry and check, being such as unsatisfactory for requirement needs gravity treatment frequency control motor 1, returns 1.；8. to each parts of non-circular gear dispenser and can
5. or 6. adjust stroke crank block device to carry out intensity, Stiffness evaluation, be such as unsatisfactory for requiring gravity treatment frequency control motor 1, return；
9. type selection calculation and the school of each standard component (rubbercushioned sleeve bearing coupling 2, brake 3, attachment screw 6, regulating bolt 7 etc.) are carried out
Core.
The principle schematic of the range-adjustable crank block device with reference to shown in Fig. 8, in Fig. 8：R represents that throw of crankshaft is long
Degree, Rmax represent maximum adjustable crank radius length, and Rmin represents minimum adjustable crank radius length, and e represents that eccentric throw (refers to song
Handle center of rotation is to the vertical dimension between slide block bearing pin center), L represents 9 haul distance of work implement；On crank disc 5
The arc groove of adjustable crank radius is provided with, by adjusting position of the regulating bolt 7 in arc groove, within the specific limits, is obtained
Throw R of different radii size, now the shift motion size of work implement 9 also there is corresponding change.
Whether produce a desired effect for test design, the range-adjustable formula interval by the present invention based on non-circular gear dispenser
The threedimensional model of mechanically moving device is imported in ADMAS, is emulated, obtain work and hold after addition constraint, kinematic pair and driving
Luggage puts 9 displacement changing curves within a period of time, as shown in figure 9, in Fig. 9：Abscissa is simulation time, and unit is the second
(s)；Vertical coordinate is exported for 9 displacement of work implement, and unit is rice (m).From Fig. 9 curve charts, apparatus of the present invention are realized
The batch (-type) linear reciprocating motion of work implement 9, and curve can continuously lead at each point, illustrate work implement
9 do not have rigid shock, can meet use requirement.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
Principle etc, any modification, equivalent substitution and improvements made etc., should be included within the scope of the present invention.
