The utility model provides an end face type chaos vibration exciter and belongs to the technical field of mechanical equipment. The end face type chaos vibration exciter is composed of an eccentric shaft, an eccentric block A and an eccentric block B, wherein the eccentric shaft is sleeved on the outer surface of a rotating center shaft in a hollow mode, the eccentric block A is sleeved at one side of the outer surface of the eccentric shaft in a hollow mode, and the eccentric block B is sleeved at the other side of the outer surface of the eccentric shaft in a hollow mode. The rotating center shaft, the eccentric shaft, the eccentric block A and the eccentric block B are all in a non-concentric structure, and the barycenters of the eccentric shaft, the eccentric block A and the eccentric block B are respectively C1, C2, and C3. The intersection angle of the eccentric shaft, the eccentric block A and the eccentric block B are respectively phi 0, phi 1, and phi 2, and both the eccentric block A and the eccentric block B are in a relationship of axial sliding and frication with the eccentric shaft. The eccentric block A and the eccentric block B is in such a relationship as that the end faces of the eccentric block A and the eccentric block B rub with each other in a sliding mode.

Background technology
Along with the development of material science and technology, the superfine grinding technology is occupied very important status in modern industry.All trades and professions become a problem that continues to solve to the demand of superfine powder so that efficiently prepare superfine powder, and the chaotic vibration grinding machine is applied to vibrating mill with the end-surface type Chaotic Vibration Exciter exactly, prepares fast the capital equipment of superfine powder.
The grinding process of vibrating mill is very long, how to shorten this process, improves the output of superfine powdery material, is the problem that vibration milling machine will solve.The movement locus that impact, friction, shear energy and the mill that affecting vibrating mill output principal element has mill to be situated between is situated between, the former has determined the effect of the each impact grinding of mill Jie, the latter has determined the uniformity of the size of the flat material of last one-tenth.The mill that how to increase vibrating mill be situated between to impact, friction, the energy sheared, and makes it have complicated three-dimensional changeable movement locus to be the main method that improves vibrating mill efficient, also to be the at present improved direction of development of vibrating mill.The energy of the impact of chaotic vibration grinding machine, shearing, friction is far longer than common vibrating mill, and has complicated movement locus, and this also is the meaning of this utility model research.
Conventional vibrating mill at the position of centre of gravity of residual battle array parts with an eccentric block as vibrator.The each several part movement locus of vibrating mill is circular motion.The circular motion that mill is situated between makes the grinding media movement layering clear and definite, exists Low Energy Region, and the energy of the impact that mill is situated between, shearing, friction is very little, and decrease in efficiency is serious.Large-amplitude vibration grinds to be situated between and is apocarpy, falls after mill Jie is tossed, exists severe impact, and material produces a large amount of energy surplus take impact comminution as main, is converted into heat energy and noise, and is energy-conservation relatively poor with environment protecting.The vibrating mill of little amplitude can cause mill Jie original place motion because the circular motion track grinds the poor fluidity that is situated between, the uneven wear that causes mill to be situated between is to make mill Jie's flowability poorer, and the result who dislikes circulation becomes worse and worse grinding process, mill Jie is that little process is accelerated simultaneously, increases the grinding cost.
