Description of drawings Fig. 1, embodiment of the invention structural representation
Embodiment encyclopaedizes the present invention below in conjunction with accompanying drawing:
With reference to Fig. 1. a kind of ore deposit grinding machine awl tooth-planetary differential speed reducer with high transmission ratio, to form by input stage bevel gear pair, high speed level NGW Gear Planet Transmission part and slow speed turbine stage planetary differential driving component, planetary differential comprises differential and quasi-planet two parts, it is characterized in that:
(A) bevel gear pair comprises the follower (23) that is contained in the interior driving wheel of tapered gearbox (22) (21) and is contained in first sun wheel shaft (24) shaft extension, and described tapered gearbox (22) is contained on support (3) the input end end face;
(B) NGW Gear Planet Transmission part comprises first sun wheel shaft (24), first planet carrier (2), first planet wheel (19), first planet wheel shaft (20) and first ring gear (1) and support (3); Described first sun wheel shaft (24) is contained in tapered gearbox (22) endoporus; Described first ring gear (1) is connected in support (3) input end endoporus; Described first planet carrier (2) output shaft partly is bearing in support (3) the inward flange endoporus with two bearings, and described first planet carrier (2) output shaft axle head internal spline connects second sun wheel shaft (9) and goes up external splines;
(C) differential component comprises second sun wheel shaft (9), second planet wheel shaft (10), second planet wheel (11), second planet carrier (12) and second ring gear (7) in the planetary differential driving component; The quasi-planet parts comprise accurate sun gear (14), quasi-planet frame (5), there won't be any problem star-wheel (15), quasi-planet wheel shaft (17) and accurate ring gear (16); The shaft extension of described second planet carrier (12) connects one and sky and is enclosed within outside second sun wheel shaft (9) with accurate sun gear (14); Said quasi-planet frame (5) relies on the cylindrical close-fitting of endoporus and support (3) inward flange and connects one and be fixed on the support (3); Described second ring gear (7) and accurate ring gear (16) are connected in respectively in the inner splined hole of the interior former of internal tooth tube (6) both sides; Said internal tooth tube (6) output terminal connects output shaft (8) disk; The other end connecting flange tube (18); Former hole middle (center) bearing (13) was bearing on quasi-planet frame (5) one side shaft journals in said internal tooth tube (6) one sides relied on; Opposite side relies on flange tube (18) two bearings of endoporus (4) to be bearing on quasi-planet frame (5) the opposite side shaft extension cylindrical, the wear-resisting circle of said flange tube (18) cylindrical close-fitting C, between said wear-resisting circle C and casing (3) endoporus according to this Zhuan Cheshi CZF-I type make up dust ring A and Che Shi TB3 rotating seal ring B.
The TB3 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 and reduces high speed rotary grinding heat.The thin lip rigidity of slip ring is little, and O type circle is tightened in slip surface the thin lip of slip ring, and unlikely being scraped of the thick 0.001-0.0025 of oil film becomes to drip (leakage); O type circle elastic force compensates sealing surface wear automatically; The CZF dust ring is made into the rectangular cross-section, is had the tight overlap joint of driving fit mouthful by low friction, high abrasion polymer, relies on the outer 0 type circle of ring to compensate automatically, is adjacent to dustproof surperficial and do not have a gap.Seal ring service condition: 0-40Mpa ,-55-250 ℃, 6m/s.
Existing ore deposit grinding machine retarder short one of the main reasons in working life is seal failure, and the volume 3.10-300 of big elder generation " mechanical design handbook " page or leaf is seen in the Che Shi sealing, and its life-span is tens times of conventional oil inside front covers.
Said ore deposit grinding machine awl tooth-planetary differential speed reducer with high transmission ratio is characterized in that: assembling conversely after second ring gear (7) can be pulled out with accurate ring gear (16), thereby ring gear can prolong one times working life.
Planet wheel is (17) three in the differential component, carries 24% moment of torsion, and there won't be any problem star-wheel is (14) 6, carries 76% moment of torsion, is equivalent to eight shuntings, thereby the high 50-60% of bearing capacity ratio background technique 200810231115.6 4 shuntings.Result of calculation such as following table:
