In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
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.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Described in seeing figures.1.and.2, a kind of slurry balance push bench cutter disk drive 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 of motor 1 and motor 1 driving, and described planetary reducer 4 output shaft installs a pinion, and equally distributed pinion collaborates to drive centre wheel 7 as planetary gear, centre wheel 7 and drive shaft 6 adopt spline form to be connected
After the power that several power set produce drives centre wheel 7 by the pinion interflow on respective output shaft, by power transmission to drive shaft 6, the driving cutterhead that drive shaft 6 and then driving are connected with drive shaft rotates.
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 of 8 groups (motor+reducer) to be evenly distributed on casing 8, the pinion be contained in like this on planetary reducer 4 output shaft just drives centre wheel 7 as a series of planetary gear interflow, and centre wheel 7 adopts involute spline to be connected with drive shaft 6, the power source at interflow is just reached drive shaft 6 and then is driven cutterhead (cutterhead and drive shaft adopt involute spline to be connected) like this.
Owing to driving cutterhead rotating, feeding time can bear larger axial force (contrary with driving cutter fed rat direction), and drive cutterhead to be connected in drive shaft 6, therefore drive shaft 6 also will bear larger axial force, therefore have employed one when designing and can bear the larger first spherical roller thrust bearing 5 of larger axis to power, thus ensure that drive shaft 6 still can work reliably under by the effect of larger top power.
With reference to shown in Fig. 3, because drive shaft 6 bears larger load and its radial dimension be connected with casing 8 is limited, its life-span of rolling bearing that traditional approach adopts will be very short and then affect life-span of whole drive unit, therefore according to drive shaft features (low-speed heave-load), devise the sliding bearing that a kind of material is Allen's metal (ZCuAl10Fe3), the sliding bearing of this kind of material has good low-speed heave-load performance under the sufficient condition of lubrication, adopts this kind of sliding bearing effectively to solve the shorter problem of drive unit main shaft bearing working life.In Fig. 1,9 is lubricant grease pipe, and it is when drive unit works, and is transported to endlessly by lubricating grease in the oil groove of slip, ensure that the lubrication of sliding bearing 10.
In addition for preventing muddy water, the impurity such as soil sand enter in drive case and drive unit are damaged, have employed material is that the native sand sealing 12 of polyurethane rubber is carried out sealing (see attached Fig. 1 and 2), the more traditional encapsulant of the joint ring of this kind of material (as NBR HNBR) there is better abrasion resistance, higher hot strength, better oil resistant and flame resistance, rotate and wear spindle for a long time with drive shaft 6 for preventing native sand from sealing 12 simultaneously, drive shaft 6 adopt the mode of interference fit install a wear-resistant sleeve 11 additional, the external surface that this wear-resistant sleeve 11 and native sand seal 12 rotating contacts adopt mid frequency induction hardening and chromed hardened technique to improve its abrasion resistance, the encapsulating method more than adopted, technique and the material selected effectively ensure that the good seal performance of drive unit.
Finally, at drive shaft rear end (away from driving cutterhead place), design the second less spherical roller thrust bearing 3 of a specification and locking nut 2, prevent drive shaft to the possibility driving the movement of cutter fed rat direction, they serve the effect of the two-way location of drive unit main shaft together with larger first spherical roller thrust bearing 5.
Beneficial effect of the present invention:
(1), adopt uniform, many groups planetary reducer to collaborate, ensure in situation about allowing in size, for cutter plate driver main shaft provides enough large power.
(2), adopt and can bear larger axis and ensure that drive shaft works reliably under axially by the effect of larger top power to the spherical roller thrust bearing of power;
(3), adopt lubrication fully, the sliding bearing that can bear low-speed heave-load material (ZCuAl10Fe3) carrys out alternative conventional rolling bearing, solves drive unit main shaft bearing due to less by radial dimension and the life-span is shorter, cannot meet the problem of actual needs.
(4), adopt the polyurethane rubber with better abrasion resistance, more high tensile, better oil resistant and flame resistant material as encapsulant, and drive unit have excellent sealing performance to adopt the mode of triple seal to ensure.
More than show and describe general 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; what describe 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.Application claims protection domain is defined by appending claims and equivalent thereof.
