Description of drawings 1, embodiment of the present 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 cone tooth-closed planetary speed reducer with high transmission ratio, is made up of input stage bevel gear pair, high speed level NGW Gear Planet Transmission part and slow speed turbine stage closed planetary driving component, closed planetary comprise differential with quasi-planet two partly, it is characterized in that:
(A) bevel gear pair comprises and is contained in driving wheel in tapered gearbox 20 18 and the follower 19 being contained in the first sun wheel shaft 22 shaft extension, and described tapered gearbox 20 is connected on support 3 input end end face;
(B) NGW Gear Planet Transmission part comprises the first sun wheel shaft 22, the first row carrier 2, the first row star-wheel 17, first planet wheel shaft 16, first ring gear 1 and support 3, described first sun wheel shaft 22 is contained in tapered gearbox 20 endoporus, described first ring gear 1 is connected in support 3 input end endoporus, described the first row carrier 2 output shaft is bearing in the endoporus of support 3 inward flange with two bearings, and described the first row carrier 2 output shaft end internal spline connects the second sun wheel shaft 9 external splines;
(C) in closed planetary driving component, differential component comprises the second sun wheel shaft 9, second planet carrier 12, second planet wheel 11, ring gear A in second planet wheel shaft 10 and internal tooth cylinder 7, quasi-planet parts comprise accurate sun gear 13, there won't be any problem carrier 6, there won't be any problem star-wheel 14, ring gear B in quasi-planet wheel shaft 15 and internal tooth cylinder 7, described ring gear A, B is processed by internal tooth cylinder 7 and obtains, described second planet carrier 12 is integrally togather empty set outside the second sun wheel shaft 9 with accurate sun gear 13, the cylindrical close-fitting of described there won't be any problem carrier 6 endoporus and support 3 inward flange is integrally togather, described internal tooth cylinder 7 output terminal connects with output shaft 8 disk, the other end connecting flange cylinder 21, described flange cylinder 21 endoporus is bearing on the cylindrical of there won't be any problem carrier 6 with two bearings 5, described flange cylinder 21 cylindrical and support 3 endoporus have two seal rings 4, it is further characterized in that seal ring 4 is for Che Shi CZF-I type combination dust ring and Che Shi TB3 rotating seal ring.
TB3 sealing is made up of thin lips and teeth shape slip ring+O type circle, and the contact of slip ring crown and surface of revolution is bordering on linear contact lay and reduces high speed rotary grinding heat.Slip ring thin lip rigidity is little, and O type circle makes the thin lip of slip ring tighten in slip surface, the thick 0.001-0.0025 of slip surface oil film, and unlikely being scraped into drips (leakage); O type circle elastic force makes line contact sealing surface wear auto-compensation; CZF dust ring is made into rectangular cross-section by low friction, high abrasion, high-strength polymer, is had closely sealed tight overlap joint mouth, relies on the outer O type circle auto-compensation of ring, is adjacent to dust-proof surface and gapless.Existing ore deposit grinding machine retarder working life, short one of the main reasons was seal failure, and Che Shi sealing sees into large elder generation " mechanical design handbook " and rolls up 3.10-300 page.
Described ore deposit grinding machine cone tooth-closed planetary speed reducer with high transmission ratio, is characterized in that: in internal tooth cylinder 7, ring gear A is equal with ring gear B number of teeth z, and modulus m is equal, thus good, the easy accessibility of process for machining performance.
In differential component, planet wheel 17 3, carries 24% moment of torsion, and there won't be any problem star-wheel 14 is 6, carries 76% moment of torsion, is equivalent to eight shuntings, and thus bearing capacity shunts high 50-60% than background technique 200810231115.6 4.Result of calculation is as following table:
