Abstract
The utility model relates to a jaw crusher and particularly relates to an improved jaw crusher. The improved jaw crusher comprises a frame, wherein a movable jaw is arranged on one side of the frame, a balance wheel is arranged on the other side of the frame, the frame is connected with the movable jaw through an inside bearing, the frame is connected with the balance wheel through an outside bearing, an eccentric shaft is arranged inside the movable jaw, both the inside bearing and the outside bearing are sleeved on the eccentric shaft, a shaft sleeve is further arranged between the outside bearing and the balance wheel, the eccentric shaft is horizontally arranged, and the outside bearing and the eccentric shaft are assembled in an interference fit manner. In the improved jaw crusher, the shaft sleeve is further arranged between the outside bearing and the balance wheel, after the improvement, the outside bearing and the eccentric shaft of the crusher are stably matched with each other, the phenomena of looseness and slipping are avoided, abrasion and rejection of the eccentric shaft can be avoided, the service life can not be influenced due to damages to the bearing, the maintenance cost is lowered, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of jaw crusher, is specifically related to a kind of modified jaw crusher.
Background technology
Jaw crusher; Inner bearing is assemblied in eccentric shaft and the moving jaw and uses interference fit, and outer bearing is bearing on the frame after being connected on the eccentric shaft by the tightly fixed liner swelling, and whole moving jaw portion is suspended on the frame; Motor drives eccentric shaft through belt pulley and rotates; Because eccentric effect makes the jaw swing, the material in the attrition crushing chamber, thus make material broken.The impulsive force that outer bearing is producing when carrying weight and the running of moving jaw portion, tightly fixed liner in use has loosening phenomenon and takes place, in case tightly fixed liner is loosening and eccentric shaft between slide, eccentric shaft and tightly fixed liner just wear and tear and scrap, bearing also can damage.
The utility model content
The purpose of the utility model provides a kind of simple in structure, can effectively reduce the wearing and tearing between eccentric shaft and the bearing, reduces the modified jaw crusher of machine maintenance cost.
The above-mentioned technical purpose of the utility model is achieved through following technical scheme:
The modified jaw crusher; The another side that the one side that comprises frame, said frame is provided with moving jaw, said frame also is provided with between stabilizer, said frame and the moving jaw and is connected through inner bearing; Be connected through outer bearing between said frame and the stabilizer, be provided with eccentric shaft in the said moving jaw, said inner bearing and outer bearing all are set on the eccentric shaft; Also be provided with axle sleeve between said outer bearing and the stabilizer, said eccentric shaft is horizontally disposed with.
As preferably, outer bearing and eccentric shaft adopt interference fit.
In sum, the utlity model has following beneficial effect:
1, the utility model is employed in and also is provided with axle sleeve between said outer bearing and the stabilizer; Through improving, cooperate stablely between disintegrating machine outer bearing and the eccentric shaft, skidding does not take place to become flexible; Eccentric shaft can not wear and tear and scrap; Bearing can not damage and influence service life, has reduced maintenance cost, has improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
This specific embodiment only is the explanation to the utility model; It is not the restriction to the utility model; Those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as in the claim scope of the utility model, all receive the protection of Patent Law.
Embodiment 1: like figure modified jaw crusher; The another side that the one side that comprises frame 15, said frame 15 is provided with moving jaw 2, said frame 15 also is provided with between stabilizer 14, said frame 15 and the moving jaw 2 and is connected through inner bearing 4; Be connected through outer bearing 9 between said frame 15 and the stabilizer 14; Be provided with eccentric shaft 1 in the said moving jaw 2; Said inner bearing 4 all is set on the eccentric shaft 1 with outer bearing 9, also is provided with axle sleeve 11 between outer bearing 9 and the stabilizer 14, and said eccentric shaft 1 is horizontally disposed with.
Outer bearing 9 adopts interference fit with eccentric shaft 1.
Claims (2)
1. modified jaw crusher; The another side that the one side that comprises frame, said frame is provided with moving jaw, said frame also is provided with between stabilizer, said frame and the moving jaw and is connected through inner bearing; Be connected through outer bearing between said frame and the stabilizer, be provided with eccentric shaft in the said moving jaw, said inner bearing and outer bearing all are set on the eccentric shaft; It is characterized in that: also be provided with axle sleeve between said outer bearing and the stabilizer, said eccentric shaft is horizontally disposed with.
