Description
Technical field
The present invention relates to a kind of walking gear box body of railway vehicle, belong to rail truck traction gear technical field of driving.
Background technique
At present, although the track vehicle product industry of China has formed the production research system of certain throughput and technical merit, about 100km/h, minority can reach 120km/h to maximum travel speed substantially.In that the circuit transport power is more and more concentrated now, in the more and more faster situation of motion speed, this series products certainly will affect the operational efficiency of circuit to a certain extent, especially can not satisfy the requirement of Line for Passenger Transportation.
In China Patent Publication No. be: CN201666353U, name is called the patent documentation of " a kind of gear case body for rail traffic vehicles ", introduced a kind of gear case body for rail traffic vehicles, its feature has: casing comprises upper box and lower box, the junction plane of upper lower box is and is in tilted layout, the bearing of input shaft seat is positioned at lower box, and oil trap has distributed in the casing.In this technological scheme, junction plane is in tilted layout, bearing of input shaft seat integral body is positioned at lower box, and to a certain extent for the layout of torsion bar reserves certain space, but torsion bar need adopt curved shape, gear-box is subjected to axially and the vertical cooperative action power of turning round of drawing simultaneously, the stressed amplification of casing, torsion bar and casing connecting screw rod are subjected to shearing stress, when high speed operation, because vibratory impulse is larger, the lifting reliability reduces; Oil trap etc. is arranged in the box inside face, makes on the one hand casing casting, processing difficulties, also affected to a certain extent the integral rigidity of casing; Owing to vent is not set on the casing, can not the balance inside and outside differential pressure, the design of sealing mechanism has been brought difficulty, and under the high-speed case, produced easily and leak; The pouring orifice position is low and flat, and with to be connected mold joint nearer, the operating space is limited, and oiling is difficulty relatively.
Summary of the invention
The object of the present invention is to provide a kind of simple and reasonable, safe and reliable, be easy to make, and can satisfy the walking gear box body of railway vehicle of high speed traveling requirement.
The technological scheme that realizes above-mentioned purpose is: a kind of walking gear box body of railway vehicle, comprise upper box and lower box, upper box is fixedly connected with lower box becomes casing, have bearing of input shaft seat and axle bearing seat on the casing, described axle bearing seat is split type structure, half is positioned on the upper box, second half is positioned on the lower box, junction plane between described upper box and the lower box is and is in tilted layout, described upper box and lower box surface distributed have some stiffening ribs, stiffening rib is stretched out by the periphery of axle bearing seat, described bearing of input shaft seat integral body is positioned on the upper box, close bearing of input shaft seat one end of the junction plane between described upper box and the lower box is lower than the end near the axle bearing seat, the angular range of described junction plane and substantially horizontal is 25 ° ~ 35 °, the bottom of close bearing of input shaft seat one end of described upper box has torsion bar and connects boss, torsion bar connects the boss bottom and has attachment hole, and the top of close bearing of input shaft seat one end of described upper box has safe support.
Described upper box top arranges the breather mounting hole.
The side of described lower box has the box house viewing window.
Has pouring orifice on the described lower box.
Described lower box one side has the oil level windshield.
The bottom of described lower box has drain oil.
The top edge position of described upper box and the lower limb position of lower box all have some processing positioning datum boss.
The connecting part arranges the reinforcement boss in the middle of the bearing of input shaft seat of described upper box and the axle bearing seat.
One side of described lower box is provided with the nameplate installation base.
After adopting the structure of technique scheme, because described bearing of input shaft seat integral body is positioned on the upper box, therefore improved on the one hand the integral rigidity of bearing of input shaft seat, be conducive on the other hand improve dimensional accuracy and the form and position tolerance of the processing of bearing of input shaft seat, satisfy the higher characteristics of input shaft rotating speed.Because close bearing of input shaft seat one end of the junction plane between described upper box and the lower box is lower than the end near the axle bearing seat, the angular range of described junction plane and substantially horizontal is 25 ° ~ 35 °, therefore, just enough spaces have been reserved for the layout of torsion bar, need not torsion bar is designed to the special-shaped shapes such as crooked, thereby gear-box can adopt the vertical lifting mode, suspension rod only is subjected to vertical pulling force, tensile stress is minimum, avoid because of the curved shape suspension rod drawing of gear-box generation being turned round combining ability, also make the design and manufacture of torsion bar more simple, reliable simultaneously; Connect boss because the bottom of close bearing of input shaft seat one end of described upper box has torsion bar, torsion bar connects the boss bottom and has attachment hole, therefore, makes torsion bar very easy with being connected of gear-box, is beneficial to simultaneously maintenance; Because the top of close bearing of input shaft seat one end of described upper box has safe support, when the torsion bar inefficacy occurs in the Vehicle Driving Cycle process, make gear-box still remain on normal home again, prevent the gear-box initiation serious accident that slides down; Also because described axle bearing seat is split type structure, half is positioned on the upper box, second half is positioned on the lower box, junction plane between described upper box and the lower box is and is in tilted layout, described upper box and lower box surface distributed have some stiffening ribs, stiffening rib is stretched out by the periphery of axle bearing seat, and is therefore simple and reasonable, safe and reliable.In addition, the breather mounting hole is set on the upper box, so that gear-box is when variable-speed operation, by the breather of installing, effectively balance gear roller box inside and outside differential pressure is conducive to the sealing of gear-box; The lower box side arranges viewing window, is convenient to observe gear-box inner body behaviour in service, is beneficial to maintenance and the maintenance of gear-box; Drain oil, pouring orifice and oil level windshield are set on the lower box, are convenient to observe oil level and oil product, more oil change is thoroughly put the rotten lubricant oil in the clean casing, is beneficial to the cleaning in the casing; Owing to be provided with some processing positioning datum boss on the upper and lower casing, be convenient to the processing and loading clamp of gear-box, the machining accuracy of favourable raising gear-box and work efficiency; The connecting part arranges the reinforcement boss in the middle of bearing of input shaft seat and the axle bearing seat, greatly improves the rigidity of casing.
