The utility model is simple in structure, stable performance, can eliminate the side force that slide block moves completely, installs and keep in repair very convenient, has extended service life of forcing press.
Advantage and disadvantage of the present utility model, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1;
Fig. 3 is the B-B cutaway view Amplified image of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in FIG. 1 to 3, the utility model comprises the flywheel shaft 1 being arranged in entablature 6, the first eccentric gear 2, the second eccentric gear 3, middle gear axle 4 and idle gear 5, the first eccentric gear 2 is fixedly connected with the second eccentric shaft 8 with the first eccentric shaft 7 be arrangeding in parallel respectively with the second eccentric gear 3, the first eccentric shaft 7 two ends and the second eccentric shaft 8 two ends are supported on respectively on longitudinal tank wall of entablature 6 both sides, it is hinged that connecting rod bearing 100 and the eccentric segment of the first eccentric shaft 7 or the eccentric segment of the second eccentric shaft 8 are passed through respectively in first connecting rod 9 upper ends or second connecting rod 10 upper ends.Middle gear axle 4 and the first eccentric shaft 7 be arranged in parallel, and middle gear axle 4 two ends are supported on the tank wall of entablature 6 longitudinal both sides by middle gear axle axle sleeve 200 respectively,
The flywheel shaft gear 11 of flywheel shaft 1 one end meshes with the first middle gear dish 41 of middle gear axle 4 one end, the second middle gear dish 42 left sides of middle gear axle 4 other ends and the first eccentric gear 2 engagements, also mesh with idle gear 5 left sides on the second middle gear dish 42 right sides, idle gear 5 right sides and the second eccentric gear 3 engagements.
The first middle gear dish 41 endoporus are fixedly connected with edge cover 43 interference fit, and locate by alignment pin 44.Edge cover 43 and middle gear axle 4 one end are by spline diameter to being connected, and middle gear axle 4 other ends radially extend the second middle gear dish 42, and edge overlaps 43 two ends respectively by two pressing plates that are put together 45 and the middle gear axle shaft shoulder 46 axial location.
