Spindelboksen med missionen om mekanisk forbindelse og kraftoverførsel

Introduction of The Spindle Box (Axle Housing)

The component that is placed on the journal of a railway locomotive or vehicle to connect the wheelset and the bogie frame or the body of a two-axle car is simply called an axle box. Its function is to transfer the weight and load of the vehicle body to the wheelset, lubricate the journal, reduce friction and lower the running resistance. The axle box, som “led” component between the bogie and the wheel and axle system, undertakes the irreplaceable mission of mechanical connection and power transmission.

Structural Design and Performance Parameters of The Spindle Box (Axle Housing)

With low alloy cast steel ZG25MnCrNi composite shell material, through the vacuum precision casting molding, tensile strength of 600mpa, yield strength of more than 350 mpa. The wall thickness of the shell has been optimized through finite element analysis. Reinforcing rib structures are set at key force-bearing parts. The overall stiffness is increased by 40% compared with the traditional design, and it can bear dynamic loads up to 25 tons. A precision bearing system with double-row tapered roller bearing units, the contact Angle of 30 ° + / – 5 ‘, and the pre-tightening force control in 0.08 0.12 mm frigang. In combination with the labyrinth sealing structure, it ensures an IP67 protection level. At a speed of 120km/h, the temperature rise does not exceed 35℃ of the ambient temperature. Intelligent automatic oil lubrication system integration equipment, equipped with pressure compensation type distributor, oil passage adopts the design of spiral groove bearing contact area by more than 95% coverage. The lubrication cycle can be extended to 120,000 kilometer, and the grease consumption is reduced to one-third of that of the traditional structure.
 

Multi-dimensional Functions of The Spindle Box (Axle Housing)

Through the three-dimensional statically indeterminate constraint design. Under the wheel-rail impact condition, the uniformity of stress distribution reaches more than 85%, and the maximum stress concentration coefficient is controlled within 1.8. Vibration energy dissipation system innovation design of rubber-metal composite bushing, the damping coefficient of 1200 n, s/m, cooperates with hydraulic damping unit, 20 hz low-frequency vibration damping can be 60%, high-frequency vibration attenuation is up to 75%. Adapt to the environment protection system co-coating on the surface of the thermal spraying WC – 12 in combination with cathodic electrodeposition process, 2000 hours in the salt fog test, no red rust. The internal positive pressure air circulation system is set up to ensure stable operation within the extreme temperature range of -50℃ to +120℃.

Intelligent Operation and Maintenance Features of De Spindle Box (Axle Housing)

The M12 standard interface is reserved, which can be connected to temperature, vibration and displacement three-parameter sensors, with a sampling frequency of up to 10kHz, to achieve real-time spectral analysis of the bearing health status. The predictive maintenance support failure model, which is based on large data, can run 2000 hours in warning, bearing an abnormal diagnostic accuracy rate of more than 92%. In combination with dedicated disassembly and assembly fixtures, the maintenance operation time is shortened to one-quarter of the traditional method. Full life cycle management modular design makes key parts replacement without overall demolition, the spare parts generalization rate rise to 80%. The design life cycle reaches 2.4 millioner kilometer, equivalent to a 15-year operation period, and the full-cycle maintenance cost is reduced by 40%.

Technology Evolution of The Spindle Box (Axle Housing)

The new generation of axle-hugging boxes is developing in the direction of material-structure-perception integration: The lightweight shell using carbon fiber reinforced metal matrix composite (CFRM) has entered the experimental stage. Embedded fiber Bragg grating sensor networks can achieve distributed measurement of strain fields. The self-healing lubrication system, through microcapsule technology, can automatically release repair factors when the temperature of the bearing rises abnormally.
