By the way that above-mentioned gusset 112 is arranged, the stability of entire 100 structure of axle box mounting base is further increased, is increased
The intensity of entire axle box mounting base 100 is added.
Further, axle box 220 includes two webs being oppositely arranged, 222, two baffles 223 and seat board 224.Tool
Body, in the present embodiment, above-mentioned 222, two baffles 223 of web and seat board 224 are welded.
Further, two baffles 223 are separately positioned on the opposite both ends of seat board 224；Two webs 222 are fixed to be connected
It is connected to the bottom of seat board 224.
Further, one word hole 221 of length above-mentioned is provided on two baffles 223.
When installation, positioning bolt above-mentioned passes through the hole on positioning gear 120 and extend to will be entire in the one word hole 221 of length
Axle box mounting base 100 and axle box 220 have been connected to.
The one word hole 221 of length can be slidably matched with positioning bolt, thus when entire process bogie axle box 10 is with work
When skill bogie moves, vibration damping can be played the role of.
Further, axle box 220 is also provided with including two gussets 225；Two gussets 225 are separately positioned on seat board 224
Both ends；And each gusset 225 is fixedly connected in seat board 224 and the baffle of corresponding end 223.
Specifically, in the present embodiment, two gussets 225 are fixedly connected on seat board 224 and gear by welding
Plate 223.
Further, axle assembly 210 is arranged between two webs 222 above-mentioned.Further, axle assembly 210
Including wheel 211, rotation section.Wheel 211 is rotationally connected with rotation section；Rotation section is fixedly connected on axle box 220.
Further, it is provided with groove 226 on two webs 222, connecting hole is provided in groove 226, rotation section is logical
Bolt is crossed to be fixedly connected in groove 226.
Further, in the present embodiment, specifically, rotation section includes axle 212, bearing 213, bearing block 214, bearing
Lid 215 and corresponding sealing element.
Further, bearing 213 uses the shock proof cylinder roller bearing of high-mechanic, and lubrication uses railway bearing specialized lithium
Base rouge, dynamic sealing is using elastic lip-shaped sealed ring.Wherein, 212 one end of axle is provided with diametrically opposite through-hole.
In use, the axle 212 on process bogie both sides is linked together with an axle sleeve, and in the logical of axle 212
Pin is plugged in hole, can thus transmit torque.
Further, the tyre tread of wheel 211 can make process bogie in the process of running with certain taper,
Accomplish automatic centering, reduce the abrasion of rail, more reduce the abrasion of 211 wheel rim of wheel, improves making for rail and wheel 211
Use the service life.
Described in brought forward, specifically, in the present embodiment, two groups of bolts hole are equipped in groove 226, using bolt by bearing block
214 are fixedly connected in the groove 226.
Further, axle box buffer rubber gasket 300 is arranged between seat board 224 and installation seat plate 110.
Entire the vertical of process bogie axle box 10 can further be enhanced by setting axle box buffer rubber gasket 300 to subtract
Vibration performance.
Specifically, in the present embodiment, axle box buffer rubber gasket 300 by steel substrate, rubber, steel panel vulcanization and
At.
