450mm Factory Customized Crane Rail Wheel Manufacturer With Forged And Casted Steel Wheelsets

Wheelsets,as well as called wheel pairs are key safety-relevant components of rail vehicle bogies.Their properties thus have an influence on such important aspects as life cycle costs and sound emissions. A wheelset is the wheel-axle assembly of a railroad car.The frame assembly beneath each end of a car,railcar or locomotive that holds the wheelsets is called the bogie.

There is a rim on the inside of the mine wheel, and there is a certain gap between the rim and the rail. The tread of the wheel contacting the rail is tapered to keep the wheel set centered when running along the track, reducing mechanical wear and reducing running resistance. Our company can produce and process various types of mining wheel pairs, such as: 600-gauge mining wheels with a diameter of 300, and 600-gauge mining wheels with a diameter of 350. The material is cast steel, and the shaft thickness is 50mm, 55mm, 60mm, 75mm, etc.

What are the reasons for the wear of the mine wheel pair?
1. Curves in the track

At the curve, in order to prevent the two axles of the mine car from entering the curve, the rim of the wheel squeezes the steel rail, causing greater driving resistance, and even the vehicle cannot proceed or fall off the road. In the curve, the track gauge must be widened, that is, the outer rail does not move, and the inner rail moves a certain distance to the center of curvature. At the same time, in order to avoid the effect of the nest force, the wheel rim squeezes the outer rail to increase the driving resistance and aggravate the wheel rim. And the wear of the rails, and even cause the rollover. The outer rail at the bend needs to be raised, and the resultant force of the centrifugal force of the minecart and its gravity may be perpendicular to the rail surface. Outside the curve, the resultant force of the centrifugal force of the mine car and its gravity cannot be perpendicular to the rail surface, that is, the centrifugal force will always exist. by centrifugal force. After a period of operation, large negative and positive deviations of the gauge at the corners appear.

2. Additional load changes

In the structure of the mine car, the box body and the axle card are rigidly connected into one. When the mine car travels on the uneven track, it will vibrate and cause additional impact load, so that the positive pressure of the mine wheel on the track increases instantaneously, resulting in The sharp increase in the pressure of the rolling elements in the bearing on the bearing ring causes plastic deformation of the rolling elements and the bearing ring, and the bearing is prematurely scrapped; at the same time, it increases the friction between the mine wheel and the track, resulting in additional wear and tear of the mine truck. .

3. Lubrication of the mine wheel to the bearing

In the special environment of underground production, after the inner sealing ring of the wheelset is compressed and worn, water and dust can easily enter, resulting in saponification of grease or loss of grease, poor lubrication, which will reduce the transmission efficiency. The phenomenon of permanent lock-rotor, the wear of the mine wheel is aggravated.

Features of Factory Customized Crane Rail Wheel Manufacturer with Forged and Casted Steel Wheelsets

Most train wheels have a conical taper of about 1 in 20 to enable the wheelset to follow curves with less chance of the wheel flanges coming in contact with the rail sides, and to reduce curve resistance. Correspondingly, the rails generally slant inwards at the same angle as the wheel cone.Shaft assembly Without the conical shape, a wheel would tend to continue in a straight path due to the inertia of the rail vehicle, reduction box​ causing the wheelset to move towards the outer rail on the curve. The cone increases the effective diameter of the wheel as it moves towards the outer rail, and since the wheels are mounted rigidly on the axle, the outer wheels push cart travel slightly farther, causing the wheelsets to more efficiently follow the curve without sideways displacement. Abnormal wear at the wheel–rail interface is thus avoided.​A loud, piercing, very high-pitched squeal usually results – especially evident on curves in tunnels, stations and elevated track.
