Why is coning of wheel done in railways?
The tread of the wheels of a railway vehicle are not made flat, but sloped like a cone in order to enable these vehicles to move smoothly on curves as well as on linear straight track. On a straight and level track also the coning of wheels help to keep the vehicle in central position.
What is coning of wheels What are the advantages of coning of wheels?
Advantages of Coning of Wheels Reduce the wear and tear of the wheel flanges and rails, which is due to the rubbing action of flanges with inside faces of rail head. (When inner rail distance is small, however outer rail distance is large). Prevent the wheels from slipping to some extent because of rigid axle.
Why is tilting of rails done?
Explanation: Tilting of rails is necessary for reducing wear and tear in addition to the lateral stresses. For this Adzing the wooden sleepers or canted bearing plates can be used.
What is coning of wheels Mcq?
Coning: Inward provision of the slope of 1:20 on the wheels of the railway wagon to counteract the centrifugal force acting the on the train. So, it enables the train wheels to cover different distances along the inner and outer curves simultaneously.
What are the advantages and disadvantages of wheel coning?
Advantages of Coning of Wheel Reduces wear and tear of wheel flanges. Damage is caused because of the friction action of rims with inner faces of the rail top. It gives an option of lateral drift of the hinge with its wheels. It prevents, to some extent, the slipping of the wheels.
What does coning mean?
Coning is when the center connective tissue of the abdomen, the linea alba, protrudes outwards beyond the rest of the abdominal wall. This tends to occur due to diastasis recti, or the normal occurring separation of the six pack abs during pregnancy.
What can be done to prevent hogging of rails?
1. What can be done to prevent Hogging of rails? Explanation: Hogging of rail can happen because of poor maintenance, faulty fastenings, etc. It can be prevented by measured shovel packing.
Which method used for the tilting of rails?
Uneven loading on the sleepers is also likely to cause them damage. To reduce wear and tear as well as lateral stresses, rails are titled at a slope of 1 in 20, which is also the slope of the wheel cone. The rail is tilted by ‘adzing’ the wooden sleeper or by providing canted bearing plates.
What is coning in brain injury?
Pressure then builds up and causes a decrease in blood flow as well as damage to the tissues. This pressure and swelling causes death by a process called ‘coning’ where the brain is forced through a small opening at the base of the skull where it meets the spinal cord.
How do I stop coning?
What can I do to avoid this (coning) from happening?
- Stop ANY exercise that promotes the coning effect.
- Look out for exercises during your 2nd and 3rd trimester that may cause coning.
- Practice safe getting up and down off the floor/out of bed.
- Ensure you are activating your deep abdominal muscles.
What is fish plate in railway?
Fish plates are specially rolled section used for joining the rails end to end with the help of fish bolts. The name fish plate is traditionally given to this fitting as its section looks like a fish. d) To allow for the expansion and contraction of rail ends due to temperature variations.
What are the advantages of Coning wheels?
Advantages of Coning of Wheels Reduce the wear and tear of the wheel flanges and rails, which is due to the rubbing action of flanges with inside faces of rail head. Provide possibilities of lateral movement of the axle with its wheels on rail curves. (When inner rail distance is small, however outer rail distance is large).
What are the disadvantages of conning wheels on railway tracks?
This will move towards the inner rail and the full advantage of conning wheels can’t be availed. In other words, there is no free lateral movement of wheels and this leads to the following disadvantages – Pressure on the outer rail is more while on inner rail it is less. This results in wear of outer rail.
Why do we not use conning wheels on curves?
Conning of wheels on curves is not of much use as the leading axle if due to centrifugal force moves towards the outer rail rear axle. This will move towards the inner rail and the full advantage of conning wheels can’t be availed.
How are the wheels of a railway vehicle connected?
The wheels of a railway vehicle are connected by an axle, which in turn is fixed on a rigid frame. Due to the rigidity of the frame, the rear axle has a tendency to move inward, which does not permit the leading axle to take full advantage of the coning.
