Description
[technical field] the present invention relates to mining machinery braking technique field, and a kind of Che Shi sealing connects adopts the machine driving speed reducing device.
[background technique] Lian Caiji is a kind of comprehensive driving, short-walling equipment, integrates cutting, walking, transhipment, spraying firing dust.Machine market is adopted by U.S. JOY company monopolizing by domestic in the past company, and its corollary equipment also all need be from external import, and the operation and maintenance cost height of equipment has increased cost of ton coal.Therefore, acceleration China connects the localization process of the machine of adopting not only can the company of filling up adopt the blank that the domestic research and development of machine are produced, and can play huge impetus to the development of Coal Mechanical simultaneously.The nearly 2 years effort of China's 31 refitting processes, successfully development was released based on the coal that domesticizes and has been shoveled the fortune equipment integrating in 2008---and ML340 even adopts machine.It is of many uses that ML340 even adopts machine, both can be used for coal mining, also can be used for tunnelling, opened new thinking for solution China three presses down the low present situation of coal recovery ratio, new means are provided, have made that reclaiming valuable coal resources efficiently and safely becomes possibility.Driving speed reducing device is to connect to adopt the machine core component, just can't work in case speed reducer damages Lian Caiji.
Background technique: 31 heavy equipment companies " a kind of driving speed reducing device " (200810013034.9) are former helical bevel gear, the driving of parallel axes, the Gear Planet Transmission significant improvement of the transmission system formed of Pyatyi altogether, its purpose simplified structure, easy to maintenance and have a high reliability.The planetary differential that is widely used in other engineering machinery (existing a plurality of inventions, utility model patent) has been adopted in this invention, thereby simplifies the structure greatly, has alleviated weight, but does not have high reliability because sealing is bad:
Because engineering machinery overwhelming majority operation in the open air, working environment is very abominable: severe winter, hot summer, mud, sand etc.Obviously, depend on sealability its working life fully, in case infiltrate foreign material, the then very fast damage of gear and bearing in the retarder leakage of oil, oil.Background technique is to rely on the fluctuate hermetical ring sealing, fluctuate hermetical ring has following problem: 1. when non-uniform temperature or stressed when inconsistent, torsional deformation can appear in the floating ring that diameter is big and thin, even small deformation very, along with slowly draining, the fine infiltration sealing layer of mud, wearing and tearing just begin until seal failure; 2. seal ring manufacture difficulty and distortion are greater than mechanical seal, and only 1 year mechanical seal life-span assert thus that the working life of floating ring can be not oversize; 3. the automatic compensation ability of fluctuate hermetical ring is poor.
[summary of the invention] the present invention is the improvement of patent of invention " a kind of driving speed reducing device " (200810013034.9), purpose provide a kind of highly reliable, the life-span is long, easy to maintenance " Che Shi sealing connect adopt the machine driving speed reducing device ".
The key of high reliability driving speed reducing device of the present invention is sealing, the technological scheme of its enforcement:
Be connected in pack into successively in the sealing seat of ring gear both sides Che Shi TB3 rotating seal ring and CZF combination dust ring.Wherein: (1) CZF dust ring is by low friction, high abrasion, high-intensity polymer T
6Be made into the dust ring of rectangular cross-section, have overlap joint mouthful on the ring, lap-joint's driving fit is tight, relies on the automatic compensating action of the outer O type circle of ring simultaneously, is adjacent to dustproof surperficial and do not have a gap.The sealability of dust ring-pressure 0-40MPa, operating temperature (40)-200 ℃, υ=6m/s, Applicable media: fouls such as silt particle; (2) TB3 Che Shi sealing is made up of thin lips and teeth shape slip ring+O type circle, and the slip ring crown is bordering on the line contact with contacting of surface of revolution, can significantly reduce the frictional heat that high speed rotating produces.The thick 0.001-0.0025 of slip surface oil film, a lubricate and unlikely being scraped become to be dripped (leakage), the elastic force of O type circle makes the wearing and tearing that are bordering on the line contact sealing face be able to automatic compensation.Lattice enclose sealability-pressure 0-30MPa, and operating temperature (550-250 ℃, υ=2m/s, Applicable media: oil, gas, water etc.The Che Shi sealing is to have the extensive Ying Yu of excellent specific property such as automatic elastic compensating, long lifetime, low friction, nothing leakage in space flight, metallurgy, field of petrochemical industry (seeing into big elder generation " mechanical design handbook " volume 2 and the relevant paper of Che Shi sealing for details).
[beneficial effect] the present invention is according to its creativeness of background technique " a kind of driving speed reducing device " (200810013034.9): (1) adopts Che Shi sealing withstand voltage, low temperature resistant, wear automatic-compensation, be in the good lubrication state in making in the retarder for a long time, thereby improved operational safety greatly, improved working life greatly; (2) first, second and third grades of shared ring gears have been simplified process for machining, and disassemble or assemble are convenient during maintenance.
