In a preferred embodiment of the invention, larger first a spherical roller thrust bearing is set also on described drive shaft, has guaranteed that drive shaft still can work reliably under the effect that is driven cutterhead larger top power.
In a preferred embodiment of the invention, described drive shaft rear end arranges less second a spherical roller thrust bearing, with larger the first spherical roller thrust bearing acting in conjunction, and the two-way location of protection drive shaft.
By technique scheme, the invention has the beneficial effects as follows:
The present invention has novel structure, reasonable in design, high reliability, has solved effectively that domestic cutterhead driving device volume is large, driving force is little, can bear the shortcoming that axial top power is little, sealing performance is bad.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present invention.
Fig. 2 is that A of the present invention is to figure.
Fig. 3 is partial enlarged drawing of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
See figures.1.and.2 described, a kind of mud water balance push bench cutterhead driving device, comprise: a casing 8, one is uniformly distributed in several power set on casing 8, described each power set comprise the planetary reducer 4 that motor 1 and motor 1 drive, and a pinion is installed on described planetary reducer 4 output shafts, and equally distributed pinion collaborates to drive centre wheel 7 as planetary gear, centre wheel 7 adopts the spline form to be connected with drive shaft 6
After the power that several power set produce drives centre wheel 7 by the pinion interflow on output shaft separately, with transmission of power to drive shaft 6, the driving cutterhead rotation that drive shaft 6 and then driving are connected with drive shaft.
Operating principle of the present invention:
Motor 1 drives planetary reducer 4 as the power source of drive unit, this power source adopts the mode (motor+reducer) of 8 groups to be evenly distributed on casing 8, the pinion that is contained in like this on planetary reducer 4 output shafts just collaborates to drive centre wheel 7 as a series of planetary gears, and centre wheel 7 adopts involute spline to be connected with drive shaft 6, and the power source at interflow is just reached drive shaft 6 and then drives cutterhead (cutterhead adopts involute spline to be connected with drive shaft) like this.
Can bear larger axial force (with driving the cutter fed rat opposite direction) owing to driving cutterhead when rotation, the feeding, be connected on drive shaft 6 and drive cutterhead, therefore drive shaft 6 also will have been born larger axial force, therefore adopted one can bear larger axis to the larger first spherical roller thrust bearing 5 of power when design, thereby guaranteed that drive shaft 6 still can work reliably under the effect that is subjected to larger top power.
With reference to shown in Figure 3, because drive shaft 6 has been born larger load and it is limited with the radial dimension that casing 8 is connected, its life-span of rolling bearing that traditional approach adopts will be very short and then affects life-span of whole drive unit, therefore according to drive shaft features (low-speed heave-load), designed the sliding bearing that a kind of material is Allen's metal (ZCuAl10Fe3), the sliding bearing of this kind material has good low-speed heave-load performance under lubricated sufficient condition, adopt this kind sliding bearing effectively to solve the shorter problem of drive unit main shaft bearing working life.In Fig. 1,9 is the lubricant grease pipe, when it is worked at drive unit, lubricating grease is transported in the oil groove that slides endlessly, has guaranteed the lubricated of sliding bearing 10.
in addition for preventing muddy water, soil sand waits impurity to enter and makes the drive unit damage in drive case, having adopted material is that the native sand sealing 12 of polyurethane rubber seals (seeing attached Fig. 1 and 2), the more traditional encapsulant of the joint ring of this kind material (as NBR HNBR) have a better abrasion resistance, higher hot strength, better oil resistant and flame resistance, simultaneously for preventing the long-term rotation wear spindle of native sand sealing 12 and drive shaft 6, adopt the mode of interference fit to install a wear-resistant sleeve 11 additional on drive shaft 6, this wear-resistant sleeve 11 adopts mid frequency induction hardening and chromed hardened technique to improve its abrasion resistance with the external surface of native sand sealing 12 rotating contacts, the encapsulating method of above employing, technique and the material of selecting have effectively guaranteed the good seal performance of drive unit.
At last, in drive shaft rear end (away from driving cutterhead place), design a specification less the second spherical roller thrust bearing 3 and locking nut 2, prevent the possibility that drive shaft moves to driving cutter fed rat direction, they have played the effect of the two-way location of drive unit main shaft together with larger the first spherical roller thrust bearing 5.
Beneficial effect of the present invention:
(1), adopt uniform, organize planetary reducer more and collaborate, guarantee on the situation that size allows, for the cutter plate driver main shaft provides enough large power.
(2), adopt and to bear larger axis and guarantee that to the spherical roller thrust bearing of power drive shaft works reliably under the effect that axially is subjected to larger top power;
(3), adopt the lubricated sliding bearing that fully, can bear low-speed heave-load material (ZCuAl10Fe3) to substitute conventional rolling bearing, solved the drive unit main shaft bearing owing to being subjected to that radial dimension is less and the life-span is shorter, can't satisfy the problem of actual needs.
(4), adopt have better abrasion resistance, more high tensile, better the polyurethane rubber of oil resistant and flame resistant material is as encapsulant, and adopts the mode of triple seal to guarantee that drive unit has good sealing performance.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
