Abstract
The invention discloses an automatic gear clearance elimination mechanism, used for eliminating a clearance of a transmission gear. The transmission gear is meshed with a fixed gear and is connected to a transmission shaft through a connecting piece, a movable gear is fixed on the fixed gear through a pin or a key, a guide sleeve is installed in an end surface hole of the movable gear, a spring is installed in a hole of the guide sleeve, a locking nut presses a press ring to tightly pressing the spring, and the transmission gear, the fixed gear and the movable gear are all helical gears. By turning the locking nut, the movable gear moves along the connecting piece, a clearance generated by abrasion between the transmission gear and the fixed gear is eliminated, and the clearance of the gear is automatically eliminated. In the invention, the transmission gear and the fixed gear in equipment do not needed to be loosened and re-adjusted for eliminating the gear clearance, the gear clearance can disappear automatically under the action of the pre-tightening force of the spring just by turning the locking nut in the process of initial installation to adjust the pre-tightening force of the spring. The invention has the advantages of convenient installation and use, stable and reliable work and free maintenance.
Description
Technical field
The present invention relates to the scrap cutter unit that uses in the cold finish rolling, finishing line of iron and steel and non-ferrous metal industry metal plate and belt, particularly in, metal sheet (scrap cutter gear transmission part and other gear transmission occasion of 0.2mm～6.0mm).
Background technique
The slitter edge processing equipment of scrap cutter after as the continuous longitudinal shear of sheet metal strip is used widely at iron and steel and non-ferrous metal industry.Driving gear is one of key mechanism of scrap cutter, because unavoidably there is the gap in common gear transmission structure, cause transmission system speed that micro-error is arranged, simultaneously, the relative position relation of upper and lower axle also can change, thereby influence is the relative position relation of corresponding blade up and down, can cause gap blade excessive and can not normally shear at work, can cause bumping problems such as cutter even device damage when more serious.Solution gear clearance commonly used at present both at home and abroad has following several usually, all has different drawbacks:
1, adopts the single shaft power mechanism, to avoid the requirement of gear clearance elimination.This structure is very simple, there is not the requirement of eliminating the gap, between two blades lap can not be arranged, during shearing, want the side clearance of strict control two blades, can not realize shearing to the plate below the 1.0mm, strip does not belong to shearing when shearing, and interrupts by force and belong to, influence the working life of blade, produced very big noise and vibrations simultaneously, belonged to low-end product, eliminated gradually.
2, rotate by the eccentric shaft driven gear and eliminate gear clearance.
3, shimming is eliminated gear clearance in the middle of differentiating gear.
4, utilize housing pin to eliminate gear clearance.
Above-mentioned 2-4 gear clearance elimination structural principle is much the same, but behind gear wear, all needs driving and driven gear is unclamped, and readjusts and eliminates gear clearance, because gear is installed in device interior more, is subjected to space and structural limitations, adjusts difficulty.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of automatic gear clearance elimination mechanism, in installation, maintenance and equipment operation process, can eliminate gear clearance automatically, with the stability in use of realizing raising equipment, the purpose that reduces plant maintenance.
For achieving the above object, technical program of the present invention lies in: driving gear and the fixed gear of realizing transmission are meshing with each other, be connected on the transmission shaft with link, it is characterized in that: carrier wheel is fixed on the fixed gear by link, and link is key or pin, in the end-face hole of carrier wheel guide pin bushing is housed, spring is contained in the hole of guide pin bushing, locking nut is pressed on the pressure ring, the pressure ring holddown spring, and driving gear, fixed gear carrier wheel are helical gear.
The present invention adjusts the pretightening force of spring by the turn locking nut, and carrier wheel is moved automatically along link, eliminates the gap that driving gear and fixed gear cause because of wearing and tearing, realizes the automatic elimination to gear clearance.
The present invention compared with prior art, do not need the driving gear and the fixed gear of device interior are unclamped, readjust and eliminate gear clearance, the rotational lock nut is adjusted the pretightening force of spring when only needing just to adorn, gear clearance can be eliminated under the effect of initial tension of spring automatically, has the characteristics convenient, that working stability is reliable, non-maintaining of installing and using.
Description of drawings
Fig. 1 is the structure diagram that link 8 of the present invention connects for pin;
Fig. 2 is the structure diagram that link 8 of the present invention connects for key.
Specific embodiments
As shown in Figure 1 and Figure 2, the present invention mainly is made up of driving gear 1, fixed gear 2, carrier wheel 3, guide pin bushing 4, spring 5, locking nut 6, pressure ring 7, link 8 and screw 9 etc.Driving gear 1 is a helical gear with fixed gear 2, is meshing with each other, and is connected on the transmission shaft with key, realizes master and slave transmission; Carrier wheel 3 is a helical gear, is fixed on the fixed gear 2 by link 8, and link 8 is key or pin, guide pin bushing 4 is housed in the end-face hole of carrier wheel 3, and spring 5 is contained in the hole of guide pin bushing 4, and locking nut 6 is by pressure ring 7 holddown springs 5, spring 5 is the dish spring, and screw 9 prevents that locking nut 6 is loosening.
Claims (3)
