This bogie truck rolling axle suspension bearing box, by two ends rolling axle suspension bearing the rolling axle-hang box is installed on the axletree, the right oil retainer washer that has maze trough is installed on the gear end axletree by interference fit, play the fixedly effect of the inner ring of rolling axle suspension bearing, the right end cap that has maze trough is installed on the rolling axle-hang box by bolt, and forming labyrinth seal with the maze trough of right oil retainer washer, the outer ring of rolling axle suspension bearing is fixed by the step in the rolling axle-hang box.Between right end cap and rolling axle-hang box, also has the O RunddichtringO.
The left oil retainer washer that has maze trough is installed on the non-gear end axletree by interference fit, play the fixedly effect of the inner ring of rolling axle suspension bearing, the left end cap that has maze trough is installed on the rolling axle-hang box by bolt, and form labyrinth seal with the maze trough of left oil retainer washer, the outer ring of rolling axle suspension bearing is fixed by bear box, can adjust the end-play of rolling axle suspension bearing by the thickness of adjusting bearing cap shim.
Whole rolling axle suspension bearing box assembling is installed on the motor by bolt, thereby realizes that motor is suspended on the axletree by the rolling axle suspension bearing box.Electrical motor one end is installed on the axletree by the rolling axle suspension bearing box, and the other end is hung on truck frame by the electrical motor suspension rod.Wiper of rubber has been installed by the larynx hoop in the outside of left end cap, and purpose is to prevent that dust from entering in the maze trough.
The rolling axle-hang box is provided with the static electricity earthing device interface, the electrolytic corrosion of the axle suspension bearing box bearing of avoiding rolling.The both sides of rolling axle-hang box are provided with the tapped bore that communicates with bearing bore, and this tapped bore is as giving the filling of rolling axle suspension bearing makeup oil, draining hole, and by the screw plug sealing, the rolling axle suspension bearing is lubricated with lubricating grease, reduces friction coefficient, life-saving.Two ends in the rolling axle-hang box also are provided with the tapped bore that communicates with bearing bore, and this tapped bore is as installing bearing device for detecting temperature hole, and seal by screw plug.
Adopt flexible axle-hang box principle of design for rice rail bogie truck axle suspension bearing box, be middle housing attenuate, two ends reinforcement.For rice rail bogie truck axle-hang box is not simply with the size reduction of Standard Guage bogie truck axle-hang box, it relate to bulk reduce back intensity, fatigue life etc. problems and with being connected of corresponding power motor oad, be a brand new structure.
The utility model bogie truck rolling axle suspension bearing box compared with prior art has following advantage: because motor rolling axle suspension bearing box structure maturation, technology are simpler, easy to maintenance, not only can fundamentally eliminate sticking watt of axle suspension bush, the slip axle suspension bearing box fuel tank of slip axle suspension bearing box structure leakage, scurry the wet goods inertial mass problem, can also reduce the resistance of motor significantly to the locomotive driving wheel, obviously improve the engagement situation of traction gear, prolonged the utilization life-span of gear.Maintenance workload when adopting this structure can effectively reduce daily utilization improves the reliability of locomotive, reduces the utilization cost, meets the requirement of the non-maintaining development of parts.
