Description
Technical field
This utility model belongs to field of track traffic, is specifically related to a kind of split type axle box.
Background technology
Bogie is the direct recipient of tractive force of train, brake force, car load and track external force, the operation to vehicle
Quality and passenger traffic safety are most important.Bogie by framework, suspension arrangement, wheel to, axle box, traction apparatus, basis system
The dynamic parts such as device, driving means are constituted, and wherein axle box is to ensure that the vitals that vehicle safety runs, its effect be by
Take turns to and framework be linked together, make wheel that the rolling along rail to be converted into the vehicle translation along circuit, it bears the weight of vehicle
Amount, the active force of transmission each side, and ensure good greasy property, make axletree that hot axle will not be occurred existing when running up
As.So the bearing capacity of axle box has strong influence to the service life of bearing.
The axle box of prior art is all-in-one-piece due to the overwhelming majority, can not meet and realize in the case of not unwheeling
Dismounting and installation wheel are right.Also having only a few is split type axle box, but the split type axle box of prior art in use exists
Following defect:
1. upper box and lower box are during assembling, owing to the two is connected by needs securing member, need certain pretension
Power, this pretightning force can cause bearing mounting hole position that deformation greatly occurs so that bearing mounting hole produces great planted agent
Power becomes oval, but axle box inherently bears huge external force, adds the effect of internal stress, easily occurs fatigue disconnected
Split.
2. can not make axle box upper and lower part accurate alignment after mould assembling.
3. axletree is when running up, and can cause bearing heating, the most bearing is not carried out monitoring temperature in prior art
Facility, be unfavorable for that driver understands traffic safety in time.
The most upper and lower casing is in unloading process, owing to pivoted arm is connected with rubber arthrosis hole, causes the upper box can be another around it
The rubber arthrosis hole of one end rotates and falls to the ground, and the safety of quality own to part and operator all can bring bad
Impact.
Utility model content
For the problems referred to above, this utility model aims to provide and a kind of assembles the split type axle box that deformation is little, precision is high.
This utility model solves the technical scheme of problem: a kind of split type axle box, including upper box and and upper box
The lower box removably connected, described upper box one end is provided with installing hole on the bearing of circular arc, and lower box is provided with circular arc
Bearing under installing hole, on described bearing, under installing hole and bearing, installing hole collectively forms a complete bearing mounting hole,
It is characterized in that: under bearing on installing hole, extend to be provided with according to the radius of curvature identical with bearing mounting hole along its edge and determine
Limit, position；
On bearing, the inwall of installing hole is respectively provided on two sides with ladder platform；
Limit, described location is inserted on bearing installing hole and fits with ladder platform surface, and the inwall of installing hole and axle under bearing
Hold the interior walls be smooth linking of installing hole；
After insertion, location limit top sides along and on bearing the two of installing hole inwall at junction, between at least leaving at one
Gap.
In such scheme, the purpose of certain interval is stayed to be contemplated to when upper and lower casing being carried out pretension with securing member, energy
Enough there is certain elastic space, it is ensured that bearing mounting hole forms a circle as far as possible, thus eliminates internal stress, it is thus achieved that as far as possible
Big fatigue life.
Limit, location can guarantee that upper and lower casing no-float during assembling, and position is accurate.
Further, on upper box both lateral sides each extend over be provided with for be connected with lower box first connection convex
Platform；On lower box, both lateral sides each extends over and is provided with the second connection boss；
First connects boss and second connects on boss and is equipped with dowel hole, and alignment pin is through the first connection boss and the
Two connect the dowel hole on boss, it is achieved the location of upper and lower casing.
This further improved plan makes, and upper and lower casing, during assembling, is beneficial to location, it is thus achieved that higher
Assembly precision.
Preferably, described upper box is provided with the temperature sensor for measuring bearing temperature.The mode used can be
Upper box arranges counterbore, temperature sensor is placed in counterbore.
Further, the described upper box other end is provided with pivoted arm rubber arthrosis hole, and this pivoted arm rubber arthrosis hole connects structure
Pivoted arm joint mounting seat on frame curb girder；
On upper box, the top, one end near pivoted arm rubber arthrosis hole is transversely provided with stop block, the transverse width of this stop block
Transverse width more than pivoted arm joint mounting seat.
Owing to upper and lower casing is in unloading process, cause upper box can rotate around the rubber arthrosis axially bored line of its other end
And fall to the ground, the safety of quality own to part and operator all can bring deleterious effect.The design of stop block, can
So that upper box is when rotated, stop block withstands pivoted arm joint mounting seat, thus prevents upper box from rotating and come off.
Remarkable result of the present utility model is:
1. the design in gap, essentially eliminates the internal stress that assembling produces, is not susceptible to fatigue fracture.
2. limit, location and the design of dowel hole, enables axle box upper and lower part accurate alignment, and assembly precision is high.
3. pair bearing carries out monitoring temperature, beneficially driver and understands traffic safety in time.
4. stop block makes upper box when rotated, and stop block withstands pivoted arm joint mounting seat, thus prevents upper box from revolving
Turn and come off.
