Abstract
The utility model relates to an independent outer rotary reducing mechanism of a rock drilling machine. The independent outer rotary reducing mechanism comprises a positioning block (1), a shell (2), a large gear (3), a small gear (8), a sliding bearing (4), a large gear bushing (5), a positioning pin (6), a needle roller bearing (7), a separation plate separation sleeve (9), a drive motor (10) and a sealing element (11). The large gear is positioned by the sliding bearing, the separation plate separation sleeve and the positioning pin, and the large gear is in clearance fit with the separation plate separation sleeve; the small gear is positioned by the needle roller bearing and the separation plate separation sleeve, and the small gear is in the clearance fit with the separation plate separation sleeve. The gear and the bearing are lubricated by utilizing oil, lubricating grease and graphite. Rotating power provided by the motor is used for driving the large gear to rotate through the small gear, so that the rotating power is transferred to a bit shank so as to complete the rock drilling task. The drive motor is independently and externally supplied with oil. The independent outer rotary reducing mechanism has the characteristics of simplicity in structure, small size, light weight, convenience in installation, small in number of inner oil passages, good manufacturability and the like.
Description
Technical field
The utility model relates to a kind of reducing gear of Independent Rotary Rock Drill, mainly as the reducing gear of hydraulic gate.
Background technology
Hydraulic gate is the main mechanical being widely used at present in mine, railway, highway, water power, coal and building engineering construction, compared with traditional air drill, it is high that hydraulic gate has energy transfer efficiency, reduce mine total installed capacity weight, improve cutting rate, improve operating condition, reduce the advantage of Drilling cost.Revolution and independent revolution form in the general employing of the slew gear of hammer drill both at home and abroad at present.Internal rotary type structure is because unstability is both ways deposited in the restriction of operating principle, and the one, card pricker, the 2nd, oil return pipe explosion.Independent rotary arrangement works is stable, and output torque is larger.
Summary of the invention
For above-mentioned situation, the purpose of this utility model is to provide a kind of reducing gear of novel independent rotary rock drill.
This reducing gear comprises: locating piece 1, housing 2, gear wheel 3, pinion 8, sliding bearing 4, gear wheel lining 5, alignment pin 6, needle bearing 7, dividing plate spacer 9, CD-ROM drive motor 10, seal 11, wherein, gear wheel 3 is interior intermeshing at housing 2 with pinion 8, between gear wheel front end and housing, be provided with sliding bearing 4, gear wheel rear end is provided with locating piece 1, is provided with dividing plate spacer 9 between gear wheel and locating piece; Gear wheel lining 5 is between gear wheel and axle; Between pinion front end and housing, be provided with needle bearing 7, pinion rear end is dividing plate spacer; The side contacting with housing at sliding bearing is provided with alignment pin 6; Between gear wheel and locating piece, be provided with seal 11; The spline joint of CD-ROM drive motor 10 and pinion afterbody.
Described gear wheel is located by sliding bearing, dividing plate spacer, alignment pin, matched in clearance between gear wheel and dividing plate spacer; Pinion is located by needle bearing, dividing plate spacer, matched in clearance between pinion and dividing plate spacer.
Utilize oil duct, the pore of enclosure interior, with fluid, lubricating grease or graphite lubrication gear and bearing.
The rotary motive power that described pinion is provided by motor, drives gear wheel revolution, thereby rotary motive power is passed to bit shank, completes rock drilling task.
Described CD-ROM drive motor is by outside independent oil supply.
The independent outer rotary structure working stability of the utility model, output torque is larger, and this structure has the features such as simple in structure, volume is little, lightweight, easy for installation, inner oil duct is few, processing technology is good simultaneously.
Accompanying drawing explanation
