Abstract
The invention relates to gearing mechanical technology field, a WGN ordinary gearing decelerator (accelerator). The decelerator (accelerator) is made up of centre gear, public gear and inner gear. It has characters of coaxial, power branch and inner engaging. Thus, the WGN ordinary gearing has merits that the bearing power is strong, the structure is compact and the efficiency is high. In the structure, the planet frame is changed in fixed frame, the structure is simpler, the process difficulty is small and the cost is low. The merits are more prominent when it is used as accelerator. The decelerator (accelerator) can replace the NGW planet gearing, three-ring, star-wheel, R series, ZDY, ZLY, ZSY hard teeth surface decelerator, and the cycloid decelerator.
Description
The present invention relates to the mechanical transmissioning technology field, a kind of WGN ordinary transmission subtracts (increasing) fast device.
Prior art NGW Gear Planet Transmission is meant the transmission type of determining with engagement system.Wherein: N is meant interior engagement, and G is meant common gear, and W is meant outer gearing.When common gear G is duplicate gear, then be called the NW Gear Planet Transmission, save the G word to show difference.NGW, NW Gear Planet Transmission have following three big characteristics: (1) input and output are on same axis; (2) can realize power dividing; (3) internal gear pair is arranged.Therefore, NGW, that the NW Gear Planet Transmission has bearing capacity is big, the little and efficient advantages of higher of boundary dimension.Elaborate NGW, NW Gear Planet Transmission theory and design with very long length invariably in many Machine Design monumental works.Solid theory makes NGW, NW Gear Planet Transmission subtract (increasing) fast device and is widely used at many industrial departments of modern times.But, it must be noted that there are following shortcoming in NGW, NW Gear Planet Transmission: (1) complex structure, the manufacturing process difficulty is big, especially requires the type difficulty of forward and reverse running bigger; (2) planet carrier will produce distortion in the running together with planet wheel, causes vibration; (3) the load balancing mechanism technology difficulty is big.NGW Gear Planet Transmission speed increaser is made In-particular under high speed, high-power situation be difficulty: gear 3 class precisions, planet carrier must be made very strict dynamic balance calibration and high performance lubrication system or the like.
The present invention proposes another kind of type of belt drive, is referred to as the WGN ordinary transmission, and its name is to make according to the order from outer gearing to interior engagement.The WGN ordinary transmission not only has three big characteristics of NGW, NW Gear Planet Transmission, and has eliminated the critical defect of NGW Gear Planet Transmission into fixed frame owing to becoming planet carrier.
Technical application scheme of the present invention: input gear (being central gear) is contained on the input shaft, and the common gear of outer gearing (or duplicate gear) is distributed on the axle of fixed frame with it, connects one with the internal gear that meshes in the common gear with output shaft.During as speed increaser, its job order is then opposite, and promptly former output shaft is an input shaft, and former input shaft is an output shaft.Obviously, the WGN ordinary transmission have coaxial, power dividing and in engagement three big characteristics.
WGN ordinary transmission of the present invention subtracts (increasing) fast device and subtracts (increasing) fast device than NGW, NW Gear Planet Transmission, its advantage: (1) is simple in structure, and the manufacturing process difficulty is little; (2), thereby do not produce vibration in the running because common gear (or duplicate gear) is to be bearing on the fixed frame; (3) low cost of manufacture, with short production cycle; Advantage when (4) being used for forward and reverse running or speedup is more remarkable.
Below in conjunction with accompanying drawing the present invention is described in detail:

With reference to Fig. 1, the WGN ordinary transmission subtracts (increasing) fast device embodiment one, mainly form by central gear (6), common gear (2) and internal gear (1), it is characterized in that input (going out) axle (5) and export (going into) axle (8) on same axis, central gear (6) is contained on input (going out) axle (5), and internal gear (1) connects with output (going into) axle (8).Uniform n between central gear (6) and (1)

c) determine.Gear (6) forms outer gearing with (2), engagement in gear (2) forms with (1).Common gear (2) is bearing on the axle (4) with rolling or sliding bearing (3), and axle and fixed frame (9) are gone up 3～8 uniform hole drive fits, and fixed frame connects with end cap (7), and end cap is connected on support (10) end face.Obviously, the WGN ordinary transmission subtract (increasing) fast utensil have coaxial, power dividing and in engagement three big characteristics.Therefore, the WGN ordinary transmission subtracts (increasing) fast device and not only has the series of advantages that the NGW Gear Planet Transmission subtracts (increasing) fast device, and owing to be fixed frame, makes structure simpler, and mechanical property is better or the like.
With reference to Fig. 2, the WGN ordinary transmission subtracts (increasing) fast device embodiment two, changes embodiment one common gear (2) into duplicate gear Zc-Zd, and purpose has been than big speed ratio.
With reference to Fig. 3, a kind of high pulling torque, the WGN ordinary transmission that boundary dimension is as far as possible little subtracts (increasing) fast device embodiment three, it is characterized in that internal gear output (going into) parts are by output (going into) axle (8), 1～6 ring gear (1), all carrying ring (12) and 6～18 uniform elastic rods (13) forms, elastic rod passes output (going into) axle disk successively, ring gear reaches and all carries upward corresponding uniform hole of ring, thereby constitute birdcage shape output (going into) parts, its two ends are bearing on the axle journal of support endoporus and fixed frame (9) by bearing (11) and (14) respectively, fixed frame (9) is connected on the end cap (7), and end cap then is connected on support (10) end face.According to theoretical calculation, the bearing capacity of gear and facewidth B and modulus m are inversely proportional to, and enlarge markedly when increasing modulus m can make boundary dimension, and weight significantly increases; And the increase facewidth, not only boundary dimension is little and weight obviously alleviates.But the width of tooth can be subjected to the restriction of gear shaping stroke and teeth directional tolerance.Adopt the multidisc ring gear to make up with elastic rod, neither be subjected to the constraint of gear shaping stroke and teeth directional tolerance, the effect because of elastic rod has compensated processing, assembly error and gear teeth resiliently deformable automatically again, thereby plays the effect of all carrying.
With reference to Fig. 4, WGN ordinary transmission two-stage tandem vertical speed reducer embodiment four, it is characterized in that: between input shaft (8) disk and vertical support (10 ') the bearing hole outer rim oil sealing (16) is arranged, oil sealing places oil sealing base (15), and oil sealing base is connected on the end face of output shaft disk.When the position of oil sealing sealing face is higher than the pasta of support shoe cream room, just can realize the function of vertical never leakage of oil.Vertical type is widely used in the reactor of chemistry, chemical industry, pharmacy, food or the like.
The WGN ordinary transmission with can obtain very big reduction speed ratio after involute less tooth difference is connected.
The WGN ordinary transmission subtracts (increasing) fast device, secondary series type and the few tooth difference pattern of connecting can replace NGW, NW Gear Planet Transmission fully, replace SH series three-ring gear reducer, star wheel reducer, SEW hard-tooth surface speed reducer, ZDY, ZLY, ZSY hard-tooth surface speed reducer and 6000 serial cycloid speed reducers.
