Specific embodiment
The utility model is further elaborated referring to Figures 1 and 2, a kind of driving preventing gnawing rail device, including in circle
The cannulated sleeve 1 of column structure, cannulated sleeve 1 are fixed in Track wheel box 10, and bearing 2, hollow sleeve are provided in cannulated sleeve 1
Multiple adjusting screws 6 being disposed radially are threaded on the cylinder of cylinder 1, the end for adjusting screw 6 is contacted with bearing outer ring 3
It connects and holds out against, bearing inner race 4 is connected with driving axle 5, and the both ends of the surface that cannulated sleeve 1 is connect with bearing 2 are provided with end cap
7。
Cannulated sleeve 1 is greater than the seamless steel pipe processing and fabricating of 8mm using wall thickness, and the internal diameter of cannulated sleeve 1 is greater than outside bearing 2
1.5~2cm of diameter.
1 surface of cannulated sleeve is provided with multiple threaded holes for installation and adjustment screw 6, and threaded hole, which includes at least, to be arranged in sky
Radial 0 °, 45 °, 90 °, 135 °, 180 °, 225 °, 270 °, 315 ° and 360 ° of the point of heart sleeve 1, and the threaded hole edge of each point
1 surface radial direction cloth of cannulated sleeve is set as double or three row's structures.It adjusts screw 6 and hot place is carried out using the technique of quenching add-back fire
Reason, wherein tempering uses temperature for 500~650 DEG C of high tempering.Using above-mentioned heat treatment process, have so that adjusting screw 6
Have a degree of toughness while having stronger rigidity, it is effectively ensured to the support force of bearing 2.
The setting of end cap 7 is mainly for dust-proof, to extend the service life of bearing.End cap 7 utilizes pin 8 and driving vehicle
Axis 5 is fixedly connected.When driving is initially installed, cannulated sleeve 1 is to be arranged concentrically with bearing 2, after gnawing rail phenomenon, passes through adjusting
Cannulated sleeve 1 is set for the eccentric with bearing 2 after screw 6 adjusts.
When initial installation, the cannulated sleeve 1 in the utility model is fixed in Track wheel box 10 to replace original axis
2 bearing block is held, is respectively provided in the threaded hole of cannulated sleeve 1 and adjusts screw 6, bearing 2 is arranged concentrically on inside cannulated sleeve 1
And tighten and adjust screw 6 to hold out against bearing outer ring 3, adjust the positioning that screw 6 is used for bearing 2, bearing inner race 4 and driving axle 5
It is fixedly connected.
It is expert at vehicle after a period of work, gnaws the generation of rail phenomenon since lifting weight will lead to.First determine whether that gnawing rail shows
As the concrete position of generation, further the related track wheel 9 and similar driving axle 5 of gnawing rail are adjusted.It adjusts
Mode is realized by screwing the adjusting screw 6 of corresponding position.Such as side rail wheel 9 is carried by excessive power vertically downward
Lotus, then the driving axle 5 of this position is acted on by downward concentrated force, and concentrated force is transmitted to bearing 2 and bearing 2 is occurred downwards
A degree of displacement, since bearing 2 is in stationary state, the active force for being transmitted to rail wheel 9 makes rail wheel gnaw rail；
At this point, for the utility model, it is only necessary to the position for axle 5 of driving a vehicle is adjusted into downwards certain displacement, driving axle 5 to
Lower adjusting is realized by adjusting the length for adjusting screw 6.Must not drive a vehicle when adjusting and lift weight, first by 0 °, 45 °,
The adjusting screw 6 of 90 °, 135 ° and 180 ° five points is unscrewed, 225 °, 270 ° and 315 ° three of 2 lower part of further progress bearing
The adjusting screw 6 of point is unscrewed, and the point of lower part three, which unscrews process, should synchronize progress, and is subject to a screw thread, must not surpass
It twists, until being adjusted to suitable position.
Further, the adjusting screw 6 of 0 °, 45 °, 90 °, 135 ° and 180 ° five points is tightened, bearing 2 is again at this time
Held out against fixation.Bearing 2 after overregulating is set for the eccentric relative to cannulated sleeve 1.
Rail phenomenon is gnawed for what rail wheel occurred, it is same to can according to need progress positioned at the rail wheel 9 of same driving axle 5
Step section adjusts the specific elongation that screw 6 is adjusted and is obtained by calculating.
The utility model simple structure and reasonable design realizes the controllability of driving axle 5 by cannulated sleeve 1, into
And the generation that rail wheel 9 gnaws rail phenomenon is effectively prevented.
