The specific embodiment
The utility model is described in further detail in conjunction with the accompanying drawings.
20 ton narrow-track mine electric locomotive reduction gears, comprise the casing that upper and lower casing is formed, drive disk assembly is set in the casing, drive disk assembly is made of totally-enclosed cylinder helical teeth～screw bevel gear two-stage transmission, the transmission of cylinder helical teeth comprise with power input bonded assembly bevel pinion axle 6, with the bevel pinion of bevel pinion axle 6 one, cooperate with bevel pinion be installed on large helical gear 3 on the small spiral bevel gear axle 1, bevel pinion axle 6 and small spiral bevel gear axle 1 be arranged in parallel up and down; The screw bevel gear transmission comprise small spiral bevel gear axle 1, with the small spiral bevel gear of small spiral bevel gear axle 1 one, the king bolt bevel gear 9 that cooperates with small spiral bevel gear, 9 interference of king bolt bevel gear are installed on the axletree 12; The casing of large helical gear 3 installation positions outwards protrudes, and is added with reinforced rib on the casing of protrusion; Bevel pinion axle 6, small spiral bevel gear axle 1, axletree 12 are installed on the casing by backup bearing, backup bearing peripheral hardware bearing cap shim, be provided with between bearing and the bearing cap shim and adjust spacer ring 11, adjusting spacer ring 11 peripheries has oil seepage hole, and the bearing cap shim that is installed on the axletree is a damascene structures.
The seal ring at speed reduction gearing seize place has the seal ring and the J-shaped seal ring of the secondary lip of band of skeleton to be used by the FB type.Speed sensor 4 is installed on the bevel pinion axle 6.
The utility model is for satisfying the situation of the little gauge of large-tonnage (600mm), adopt totally-enclosed cylinder helical teeth-screw bevel gear double reductor, the drop-gear box casing adopts carbon constructional quality steel to be welded, should carry out annealing in process after the welding, casing adopts split type structure, casing has been considered integral intensity and rigidity in design, and especially bearing seat flange place is added with reinforced rib, helps the casing heat radiation.
It is little that the utility model mainly solves installing space, the problem that transfer torque is big.Because installing space is little, for guaranteeing installation at little gauge, casing has reduced the axletree axial space as much as possible, and roller bearing end cap is designed to insert bearing lid 13, and its structure is light and handy, need not Bolt Connection, reduced certain space, the fastening attachment face of casing as far as possible inwardly contracts, and large helical gear 3 installation positions are outwards outstanding, be added with reinforced rib on the outstanding casing, guaranteed the high pulling torque transmission under little gauge.Power passes to bevel pinion axle 6 by versatile spindle by motor, slows down through one-level, passes to low speed turbine stage small spiral bevel gear axle 1 by large helical gear 3, behind double reduction, passes to wheel by king bolt bevel gear 9 drive wheels is rotated.The sealing at speed reduction gearing seize place is adopted is the seal ring of FB type the secondary lip of band that skeleton is arranged and the contact-type seal that the J-shaped seal ring is used, this hermetically-sealed construction is simple, cost is lower, and sealing effectiveness is good, for guaranteeing the installation under little gauge, stretch to box house as far as possible at the position of on the bearing cap shim seal ring being installed, and reduces occupying of space outerpace.Be to guarantee the adjustment of bearing clearance and gear mesh sideshake, design has the spacer ring 11 of adjustment, and adjusting spacer ring 11 peripheries has oil seepage hole, be convenient to splash lubricated have flow into bearing inner ring from wall box along oil groove; Aging for preventing corrosion, the packing seal at the stifled place that drains the oil adopts the sealing of red copper pad, and sealing is reliable.
Because mounting center is apart from two gear reference centre distances difference being arranged, speed reduction gearing one-level reducing gear described in the utility model adopts involute helical teeth cylinder profile shifting gear, what adopt is not wait the positive drive of moving in the Modified Gear Transmission (claiming the angle correcting gear transmission again), the big gear wheel normal shift, the miniature gears negative addendum modification.Large helical gear 3 adopts has the key slight interference to connect, and the advantage of involute cylindrical helical gear drive is that transferring power is steady, and noise is little, the load-carrying capacity height, and processing technology is simple.What double reduction adopted is tapered tooth such as bottom clearance such as grade, the transmission of spiral curve-tooth bevel gear quadrature of circle-arc tooth system, and king bolt bevel gear 9 is to connect hot jacket on axletree through interference, keyless joint.Spiral curve-tooth bevel gear transmission advantage is because of the tooth trace on the umbrella shape crown is a circular arc, the load-carrying capacity height, and running is steady, and noise is little, and is insensitive to installation error and distortion.
Because speed reduction gearing gear transmission described in the utility model has the existence of axial force, backup bearing all adopts tapered roller bearing.
For carrying out speed monitoring, on one-level deceleration bevel pinion axle 6, speed sensor 4 is installed.
Now existing 40 of speed reduction gearing described in the utility model is installed on CJY20/6P type that our factory produces, 20 tons of stringing formulas of the CJY20/6PA type industrial-mineral electric locomotive, try out under mine, its transfer torque is big, volume is little, stable drive, noise is little, and running condition is good, any torsional deflection did not appear in casings etc., had obtained extraordinary effect.
