Description
Technical field
The utility model relates to biomass forming machine technical field, specifically a kind of eccentric wheel installation shaft of biomass forming machine.
Background technology
Biomass forming machine refers to crops, solid waste such as the maize straw in rural area, wheat stalk, cotton stem, straw, rice husk, peanut shell, corncob, branch, leaf, sawdusts as raw material, pressurization after pulverizing, density is shaping, produces the machine of " straw and coal ".Operationally, push rod is very large to the impact forces of poly-material mould for biomass forming machine, and the reciprocating frequency of push rod is than very fast.In existing biomass forming machine, the mode that main shaft and eccentric junction adopt key to be connected so that detachable maintaining, but due to moment of torsion between eccentric wheel and main shaft large, key connects and there is gap, and the mode causing key to connect often breaks down.In addition, have people to adopt the form of heat expansion to be connected main shaft and eccentric wheel, although reduce fault rate, repair demolition difficulty increases.
Utility model content
The purpose of this utility model is to provide biomass forming machine eccentric wheel installation shaft, for solving the problem that on biomass forming machine, easily break down in main shaft and eccentric wheel junction, and is convenient to main shaft and eccentric dismounting, maintenance.
The technical scheme in the invention for solving the technical problem is: biomass forming machine eccentric wheel installation shaft, comprise axis body, it is characterized in that, the first separate installation portion and the second installation portion is provided with at the middle part of described axis body, first, second installation portion is truncated cone-shaped, the outer wall of described first installation portion and the second installation portion is respectively equipped with some tapered planes, and the axis of tapered plane described in each and axis body acutangulates angle; Drive division is provided with at the two ends of described axis body, two back-up rings are provided with at the middle part of described axis body, at described drive division and the first installation portion, be respectively equipped with nut between drive division and the second installation portion, the nut cooperatively interacted coordinates with back-up ring and realizes eccentric axial limiting.
Further, the number of the tapered plane on described first installation portion or the second installation portion is one to four.
Further, the number of described tapered plane is three.
Further, the angle angle of described tapered plane and axis body axis is 0.5 °-2 °.
Further, the angle angle of described tapered plane and axis body axis is 0.8 °.
Further, described drive division is provided with keyway.
The beneficial effects of the utility model are: the biomass forming machine eccentric wheel installation shaft that the utility model provides, axis body arranges tapered plane, the setting of tapered plane achieves axis body and eccentric synchronization action, and it is very close to each other between the two, avoid the damage of key under the effect of impulsive force when adopting key to connect, long service life.Eccentric wheel is arranged on after on axis body, realizes eccentric axial limiting by back-up ring and nut, installation, convenient disassembly, be convenient to maintenance.

Fig. 1 is graphics of the present utility model;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the top view of Fig. 1;
Fig. 4 is the A-A sectional view in Fig. 2;
In figure: 1 axis body, 2 first installation portions, 3 tapered planes, 4 drive divisions, 5 second installation portions, 6 back-up rings.
Detailed description of the invention
As shown in Figures 1 to 4, the utility model mainly comprises axis body 1, first installation portion 2, drive division 4 and the second installation portion 5, is described in detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, axis body 1 is main body of the present utility model, spaced first installation portion 2 and the second installation portion 5 is provided with at the middle part of axis body, first installation portion and the second installation portion separate, first, second installation portion is truncated cone-shaped, namely the outer wall of first, second installation portion is coned face, and the first installation portion and the second installation portion coordinate setting-up eccentricity to take turns respectively.First installation portion and the second installation portion are respectively equipped with tapered plane 3, as shown in Figure 4, the outer wall of the first installation portion or the second installation portion are respectively equipped with several tapered planes, there is between tapered plane and the axis of axis body an acute angle.The acquisition of tapered plane, the outer wall by milling axis body obtains.The middle part of whole axis body is thick, two ends thin, and the some tapered planes on the first or second installation portion surround the taper of a tip towards axis body two ends, like this, can facilitate eccentric installation.On first or second installation portion, the number of tapered plane is at least one, also can be two, three, even more.The setting of tapered plane, make the profile of the first or second installation portion no longer for circular, the profile of eccentric installing hole and the first or second installation portion adapts, and therefore, when axis body rotates, can realize axis body and eccentric synchronous axial system.
Be respectively equipped with drive division 4 at the two ends of axis body, drive division is provided with keyway, and axis body is fixedly connected with driving pulley by drive division.
The angle of tapered plane and axis body axis is 0.5 °-2 °, and arranging of tapered plane can ensure main shaft and eccentric synchronization action, and for face contacts between main shaft with eccentric wheel, compare linear contact lay when key connects, not fragile, and gapless between main shaft and eccentric wheel, synchronism is better; The optimum value of this angle angle is 0.8 °.Axis body two ends are thin, middle thick, are convenient to eccentric installation.
Be provided with back-up ring 6 at the middle part of axis body, acting as of back-up ring carries out axial limiting to eccentric wheel, at drive division and the first installation portion, arranges nut respectively between drive division and the second installation portion, is realized eccentric axial location with coordinating of back-up ring by nut.
