Abstract
The utility model relates to arranging an eccentric gear which has the same eccentric distance and is engaged with each other separately on the power output shaft in the transmission case or moment transmission case and the sub-driven shaft. When the sub-driven shaft is rotating evenly, the eccentric gear on the drives the eccentric gear on the power output shaft and makes the power output shaft rotate in a variable motion and moment.
Description
The utility model relates to mechanical reduction speed change bending moment case, is adapted to the automatic speed-changing and torque-converting in the mechanical transmission especially.
At present, the speed changer that lease equipment generally uses, the rotating speed and the moment of output terminal output are fixed.And in fact have many machinery, the load in a period of rotation usually to change, as the imbibition and the discharge opeing process of reciprocating pump; The load of the upstroke of petroleum industry oil well pump and down stroke etc. changes.At present, solving the rotating speed of speed changer output terminal output and the way of moment variations, mainly is the variation according to load, and motor is implemented frequency translation, i.e. converter technique.To achieve the above object.This method exists technical sophistication, investment is big, and shortcomings such as poor reliability are so be difficult to apply.
The purpose of this utility model is: provide a kind of simple in structure, reliable operation is when rotating speed, moment one timing of speed changer power intake input power, the then continuous novel speed change bending moment case that changes of the rotating speed of this speed changer output terminal output and moment.To adapt to the problem that the speed changer clutch end changes at a period of rotation internal burden.
The technological scheme that its technical problem that solves the utility model adopts is:
With reference to Fig. 1, Fig. 2 and Fig. 3
On the pto 8 in speed change bending moment casing 1 and the driven shaft 6 of time one-level, be separately installed with the identical and intermeshing eccentricity gear group of throw of eccentric: eccentricity gear 3 and eccentricity gear 2.When driven shaft 6 uniform rotation of inferior one-level, the eccentricity gear 3 that the eccentricity gear 2 on the driven shaft 6 drives on the ptos 8 rotates, and makes pto 8 in rotating a circle, and does the rotation of speed change degree, variable force square.That is: power is exported by pto 8 after driving gear 5 driven gears 7 driven shafts 6 eccentricity gears 2 pass to eccentricity gear 3 by power input shaft 4 inputs.
In the speed change bending moment casing 1 some grades of driven gears and driven shaft can be arranged, eccentricity gear 2 is contained on the driven shaft 6 of time one-level with driven gear 7 strings, and another eccentricity gear 3 is installed on the pto 8.Eccentricity gear 2 and eccentricity gear 3 are intermeshing.Distance between driven shaft 6 and the pto 8, the distance of two between centers when being the semi major axis end engagement of the short radius end of an eccentricity gear and another eccentricity gear, guarantee thus to mesh all the time when eccentricity gear 2 drives eccentricity gear 3 rotations, the driven shaft 6 of inferior one-level is when uniform rotation, eccentricity gear 2 is rotated drive eccentricity gear 3 rotations, to drive pto 8
In rotating a circle, do the rotation of speed change, bending moment.
One group of eccentricity gear is housed in the speed change bending moment case usually, 2～3 groups of eccentricity gears also can be housed as required.On every group of eccentricity gear assembly mark is arranged, with pto 8 assembly mark is arranged, there is position mark the termination of pto 8.Be convenient to assembling and installation.
Characteristics of the present utility model are: simple and reliable eccentricity gear group makes that it is simple in structure owing to having adopted in the utility model, reliable operation, life-span are long, clutch end is in a cycle of motion, speed and moment are changed simultaneously automatically, thereby can be widely used in fields such as mechanical industry and petroleum production.
The utility model is described in further detail below in conjunction with accompanying drawing and implementation column:
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the sectional drawing of the eccentricity gear group engagement in the utility model.

With reference to Fig. 1
The utility model is on the driven shaft 6 of pto 8 and time one-level in speed change bending moment casing 1, is separately installed with the identical and intermeshing eccentricity gear group of throw of eccentric: eccentricity gear 3 and eccentricity gear 2.When driven shaft 6 uniform rotation of inferior one-level, the eccentricity gear 3 that the eccentricity gear 2 on the driven shaft 6 drives on the ptos 8 rotates, and makes pto 8 in rotating a circle, and does the rotation of speed change degree, variable force square.That is: power is exported by pto 8 after driving gear 5 driven gears 7 driven shafts 6 eccentricity gears 2 pass to eccentricity gear 3 by power input shaft 4 inputs.
