What is the magazine?
Journal Box is a housing unit in the wheel assembly and assembling axle designed to maintain the oil supply for axle and axle bearings. These diaries are in fact part of the axle and are a type of bearing that does not actually move independently of the wheel. The diary simply allows the wheel movement to be independent of the axle that creates the strength of the friction between the wheels and the axle on which it is located.
This friction between the wheels and the axle must be minimized to prevent the wheel from overheating, which can be fragile and cause it to break into pieces. The magazine is the lubrication method for the interior of the diary. It acts as a housing for the necessary oil lubricant.
Most diary boxes located on railway cars are machined from the same material as the IS axle. This means that boxes on magazines are usually made of thick steel that has been eased ortreated with heat to be strong. The box must be able to hold the lubricant without leakage, which means that it must also be made of a material that can withstand exposure to the external elements. The boxes are mounted on the outside of the wheel. This is another reason why it must be made of durable material, because it has virtually no protection against abuse of harsh travel, which must withstand many freight trains and rail cars.
Diary boxes are located on the outside of the wheel, directly at the end of the axle and mounted between the frame rails for the entire wheel devices. Placing the box is an essential factor in its main function, as it provides the lubricant directly at the end of the axle. This in turn allows the lubricant to reduce the amount of friction created between the wheels and the axle.
The magazine box is also located in a way that prevents its interference to wijakákoli from moving parts in the wheel of the railway car and the brake system. This is another important location factor. If the diary field should escape the lubricant inside, it could end the lubrication of the brake or the wheel itself if it was placed anywhere else.
The interior of the Journal field is easily accessed from the outside of the wheel. It is usually accessible through the closed door that is locked by pressure to prevent leakage. This is from this point that the bearing and the diary field itself can be repaired or the box boxes can be supplemented with a lubricant of the bearing.
