Portion's installation frame upper plate, in the bottom mounting seat of work housing, work housing with and the drive pulley that is connected of motor it
Between decelerator is installed.This decelerator mainly includes a noncircular gear pair, a knuckle-tooth wheel set and one group of bevel gear differential wheel
System.Wherein, its wheel shaft of the drive pulley being connected with motor by transmission belt is connected with the input shaft of decelerator or is same axis,
This input shaft is provided with two gears, and one is non-circular gear A, and another is Knucle-gear A, this non-circular gear A and another
The non-circular gear B engagement that profile cooperates, another Knucle-gear A is engaged with another Knucle-gear B.This Knucle-gear B sets center
Through hole, it is connected with one end of hollow axle, the central through hole of one of this hollow axle other end and differential gear train angular wheel A
It is connected, this bevel gear A is engaged with bevel gear B, this bevel gear B is engaged with another bevel gear C again, the gear shaft of non-circular gear B
Extend across the hollow axle of Knucle-gear B to Knucle-gear B direction, end is vertical with the gear shaft through bevel gear B central through hole
Connect, the wheel shaft of described bevel gear C is additionally provided with a driving gear, and the wheel shaft of the wheel shaft of bevel gear C and non-circular gear B
Coaxial line, described driving gear is meshed with the tooth bar being connected on work housing.
The present invention compared with prior art has the advantage that：
1st, rate curve is smoother, and accelerating curve limit is less, and that is, peak acceleration is little.The operation of rolling is more steady.
2nd, under identical production efficiency, robust motion is good, and impact shock is little, and product quality is high.

Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
Simplified schematic diagram is cutd open by the cold pilger mill main view office that differential gear train combines commutation with non-circular gear that relies on shown in Fig. 1
In, four framework lateral plates 5 be respectively cooperating with being arranged on topping roll support 9 and bottom roll support 6 and topping roll 8 and bottom roll 7
Surrounding, collectively constitutes work housing, in work housing top loader frame upper plate 10, in the bottom mounting seat of work housing
4, with and the drive pulley 2 that is connected of motor 1 between, decelerator 3 is installed in work housing.In fig. 2, this decelerator mainly wraps
Include a noncircular gear pair, a knuckle-tooth wheel set and one group of bevel geared differential gear train.Wherein, it is connected with motor by transmission belt
Its wheel shaft of drive pulley is same axis with the input shaft 21 of decelerator, and this input shaft is provided with two gears, and one is non-
Knucle-gear A11, another is Knucle-gear A13, and the non-circular gear B12 that this non-circular gear A is cooperated with another profile engages,
As shown in figure 3, another Knucle-gear A is engaged with another Knucle-gear B14.This Knucle-gear B sets central through hole, and it is with hollow axle 20
One end be connected, this hollow axle other end is connected with the central through hole of one of differential gear train angular wheel A15, this bevel gear
A is engaged with bevel gear B16, and this bevel gear B is engaged with another bevel gear C17 again, the gear axial direction Knucle-gear B of non-circular gear B
Direction extends across the hollow axle of Knucle-gear B, end with through bevel gear B central through hole gear shaft vertical be connected, described
One driving gear, and the wheel shaft coaxial line of the wheel shaft of bevel gear C and non-circular gear B, institute are additionally provided with the wheel shaft of bevel gear C
State driving gear and be meshed with the tooth bar being connected on work housing.
Noncircular gear pair should engage as shown in Figure 3 in initial position, because the gear teeth of non-circular gear are one-to-one
Relation, so can not arbitrarily coordinate it should allow specific two gear teeth meshing in initial position.
The work process of the present invention approximately as：
The moment of torsion of motor output is sent on input shaft through drive pulley and drives non-circular gear 11 and Knucle-gear 13 to rotate,
Gear 11 and 13 drives 12 and 14 motions again respectively, and the motion of non-circular gear 12 is input in differential gear train by tie-rod H, knuckle-tooth
The motion of wheel 14 is input in differential gear train by hollow axle, then exports in driving gear 18 by bevel gear 17, gear 18
It is meshed with tooth bar 19, tooth bar 19 is fixedly connected with work housing again, be also equivalent to gear 18 and drive work housing to carry out back and forth
Motion.
Being conceived based on of above-mentioned work process：Non-circular gear is used to transmit two between centers non-uniform movements, non-knuckle-tooth
The compact conformation of wheel set, rigidity are good, gear ratio is more steady, easily realize dynamic balancing.Due to a pair of non-circular gear do not enable non-
Dull corner functional relationship, so the method being combined with differential gear train using noncircular gear pair, two motions is simultaneously entered
Differential gear train and allow synthesis motion be two input motions difference, this resultant motion is output campaign, and output corner should be
Continuous swing, by the cooperation with tooth bar, to realize the reciprocating motion of work housing.
