Flat car axle box oil lubricating device

Abstract

The invention discloses a flat car axle box oil lubricating device comprising an axle. The axle comprises a wheel pair mounting section, an anti-dust stop ring seat and a journal, a bearing is arranged at the journal, and a wheel box body is arranged on the outer side of the bearing. A front cover and a rear cover are arranged on the two sides of the bearing, an anti-dust stop ring is arranged onthe anti-dust stop ring seat and abuts against the rear cover, and an axle end baffle is fixed to the end of the axle through nuts. The outer diameter of the journal is 160 mm, the length of the axleis 2253 mm, and the bearing is a 352132 type bearing. The flat car axle box oil lubricating device has the advantages that an excessively heated axle failure frequently occurring in a 100-T flat car is fundamentally eliminated; and the flat car axle box oil lubricating device is suitable for a 120-T flat car, the exchanged use range of spare parts is increased, and the storage type and number of the stock spare parts can be decreased to a certain extent.

Description

technical field [0001] The invention relates to the technical field of locomotives, in particular to an axle box lubricating device. Background technique [0002] Wheelset bearing axle box oil lubrication device is an important part of vehicle bogie. Its main function is to connect the wheel set and the side frame into one, and transmit the vertical and horizontal loads of the vehicle to the wheel set; it can lubricate the journal to reduce friction, reduce running resistance, and prevent the shaft from burning; limit the excessive lateral movement of the wheel set And vertical movement, play the role of positioning; prevent rain, dust and other foreign matter from intruding, play the role of sealing, so as to ensure safe operation. [0003] The combustion shaft mentioned in daily vehicle management refers to the high heat, that is, the hot shaft, due to the failure of the oil lubrication device of the bearing axle box. Combustion shafts generally show that the bearing tem...

AI Technical Summary

Problems solved by technology

[0008] (1) The structure of the bearing lubricating device is not ideal. The 100T flatbed truck adopts a shaftless rolling bearing device, the bearing is exposed outside, and the bearing has a sealing cover, which is not conducive to maintenance and timely adding lubricating oil

[0009] (2) The selection of bearings is unreasonable. The bearings used in 100T flatbed vehicles are 172734T cylindrical roller bearings, which are only used in this type of vehicle.

[0010] Due to the existence of the above shortcomings, the failure of the fuel shaft of the vehicle occurs frequently, which seriously affects the performance and efficiency of the vehicle.
