Description
Technical field
The utility model relates to a kind of rail vehicle walking gear box body, belongs to rail truck traction gear technical field of driving.
Background technique
At present, though 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 basically.In that the circuit transport power is more and more concentrated now, under the more and more faster situation of motion speed, this series products certainly will influence the operational efficiency of circuit to a certain extent, especially can not satisfy the requirement of Line for Passenger Transportation.
At the Chinese patent publication number be: CN201666353U; Name is called the patent documentation of " a kind of gear case body that is used for rail traffic vehicles "; Introduced a kind of gear case body that is used for rail traffic vehicles, its characteristic has: casing comprises upper box and lower box, and the junction plane of last 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, and bearing of input shaft seat integral body is positioned at lower box; To a certain extent for the layout of torsion bar reserves certain space, but torsion bar need adopt curved shape, and gear-box receives 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 receive shearing stress, when high speed operation; Because vibratory impulse is bigger, the lifting reliability reduces greatly; Oil trap etc. is arranged in the box inside face, makes casing casting, processing difficulties on the one hand, also influenced the integral rigidity of casing to a certain extent; Owing to vent is not set on the casing, can not the balance inside and outside differential pressure, the design of sealing mechanism is brought difficulty, and under the high-speed case, be easy to generate leakage; 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 purpose of the utility model be to provide a kind of simple and reasonable, safe and reliable, be easy to make, and can satisfy the rail vehicle walking gear box body of high speed traveling requirement.
The technological scheme that realizes above-mentioned purpose is: a kind of rail vehicle walking gear box body; Comprise upper box and lower box, upper box is fixedly connected with lower box becomes casing, has bearing of input shaft seat and axle bearing seat on the casing; Said axle bearing seat is a split type structure; Half is positioned on the upper box, and second half is positioned on the lower box, and the junction plane between said upper box and the lower box is and is in tilted layout; Said upper box and lower box surface distributed have plurality of strengthening ribs; Stiffening rib is stretched out by the periphery of axle bearing seat, and said bearing of input shaft seat integral body is positioned on the upper box, the junction plane between said upper box and the lower box be lower than a end near bearing of input shaft seat one end near the axle bearing seat; The angular range of said junction plane and substantially horizontal is 25 ° ~ 35 °; The bottom near bearing of input shaft seat one end of said upper box has torsion bar and connects boss, and torsion bar connects the boss bottom and has attachment hole, and the top near bearing of input shaft seat one end of said upper box has safe support.
Said upper box top is provided with the breather mounting hole.
The side of said lower box has the box house viewing window.
Has pouring orifice on the said lower box.
Said lower box one side has the oil level windshield.
The bottom of said lower box has drain oil.
The top edge position of said upper box and the lower limb position of lower box all have some processing locating basis boss.
The connecting part is provided with the reinforcement boss in the middle of the bearing of input shaft seat of said upper box and the axle bearing seat.
One side of said lower box is provided with the nameplate installation base.
After adopting the structure of technique scheme; Because said bearing of input shaft seat integral body is positioned on the upper box; Therefore improved the integral rigidity of bearing of input shaft seat on the one hand; Help improving the dimensional accuracy and the form and position tolerance of the processing of bearing of input shaft seat on the other hand, satisfy the higher characteristics of input shaft rotating speed.Since the junction plane between said upper box and the lower box be lower than a end near bearing of input shaft seat one end near the axle bearing seat; The angular range of said junction plane and substantially horizontal is 25 ° ~ 35 °, therefore, has just reserved enough spaces for the layout of torsion bar; Need not torsion bar is designed to special-shaped shapes such as bending; Thereby gear-box can adopt the vertical lifting mode, and suspension rod only receives vertical pulling force, and tensile stress is minimum; Avoid drawing of gear-box generation being turned round combining ability, also make the design of torsion bar simultaneously and make simple more, reliable because of the curved shape suspension rod; Connect boss because the bottom near bearing of input shaft seat one end of said 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 maintenance simultaneously; Again because the top near bearing of input shaft seat one end of said upper box has safe support, when torsion bar taking place in the vehicle driving process lost efficacy, make gear-box still remain on normal home, prevent the gear-box initiation serious accident that slides down; Also because said axle bearing seat is a split type structure; Half is positioned on the upper box; Second half is positioned on the lower box, and the junction plane between said upper box and the lower box is and is in tilted layout, and said upper box and lower box surface distributed have plurality of strengthening 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, makes gear-box when variable-speed operation, through the breather of installing, effectively balance gear case inside and outside differential pressure helps the sealing of gear-box; The lower box side is provided with viewing window, is convenient to observe gear-box inner body behaviour in service, is beneficial to the 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 locating basis 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 is provided with the reinforcement boss in the middle of bearing of input shaft seat and the axle bearing seat, improves the rigidity of casing greatly.
