ZBL600/350 Mining Car Iron Wheel Set
ABOUT US
The solid steel wheel is mainly used to reduce the friction of the mine car on the ground so that the mining car can be walked. The rail wheel is the same as the bicycle wheel, reduce friction, so mining car can move safely and quickly, which reduces the wear and tear of the machine and reduces The resistance, which also reduces the manpower. So the life of the underground mining car can be used longer.

Product Description

Wheelsets are divided into vehicle wheelsets and locomotive wheelsets. The locomotive wheel set can be divided into steam locomotive wheel set, diesel locomotive wheel set, electric locomotive wheel set and moving axle wheel of EMU. The moving axle wheel sets of diesel locomotives, electric locomotives and EMUs are equipped with transmission gears on the axle shafts. Modern high-speed passenger cars and EMUs all use disc brakes, and brake discs are installed on the axle shafts or wheels. The wheel set of steam locomotive is divided into guide wheel set, driving wheel set, follower wheel set and coal water wheel set. The guide wheel set is located in the front of the locomotive and plays the role of locomotive guidance. The driving wheel set plays the role of transmitting locomotive power. The driving wheel set is directly driven by the cylinder piston (piston) through the rocker, and the other driving wheel set is driven by the driving wheel through the connecting rod. There are cranks, crank pin holes and equalizing blocks on the wheel center of the moving wheel set, and the cranks of the left and right wheels should have a 90 ° phase difference during assembly. The bearings of the driving wheel and guide wheel are inside the wheel. The secondary wheel set and coal water wheel set are similar to those of passenger and freight vehicles.
The wheel set can be divided into rolling bearing wheel set and sliding bearing wheel set according to the bearing type applicable to the axle. The passenger cars of China's railways have all been adopted, and the number of freight cars using rolling bearing wheel sets is also increasing.
According to the difference of the maximum allowable axle load (the maximum static pressure of the wheel set on the steel rail), the freight car sliding bearing wheel sets are divided into four types: B, C, D, E, and the dimensions of each part of the axle and wheel of each type of wheel set are different except the wheel diameter; There are also three types of rolling bearing wheel sets for passenger cars and freight cars: RC, RD and RE. In addition, different types of rolling bearing have different journal lengths in the same type of wheel sets, which can be distinguished by the following marks, such as RC, RD, etc. The axle is forged with medium carbon high-quality steel to form a cylinder with different diameters of each section. It can be divided into locomotive axle and passenger and freight car axle according to vehicle type. It can be divided into sliding bearing axle and rolling bearing axle according to bearing type.
Advantages of tramcar wheel set:
(1) M-shaped seals are used. The m-shaped seal is a combined type. A spring is installed on the inner side of the main lip to keep it in close contact with the journal and automatically compensate for the gap caused by the wear of the lip. The main and auxiliary lips turn outward, which can effectively prevent the immersion of water and coal slime, and has excellent dustproof and waterproof capabilities.
(2) Ma series special bearings for mine cars are used. The bearing is made of large diameter steel ball, which increases the radial clearance of the bearing, and a single-sided open nylon cage with high strength and good toughness is selected. According to the laboratory measurement, its rotation resistance is only 1/5 of that of ordinary bearings, and its anti seize life is more than 615 times of that of ordinary bearings.
(3) The m-shaped seal can effectively prevent the invasion of coal slime and coal dust. After a long period of operation, when the coal dust and mud water gradually enter the bearing, the wheels can still operate normally due to the excellent anti seize performance of the special bearing for the mine car, so that the service life of the new type of mine car wheel set is more than 3 times longer than that of the old structure wheel set, effectively reducing the resistance coefficient of the mine car operation. The advantage of the new wheel set is that due to the change of the waterproof and dustproof capacity of the new mining car wheel set, the service life has been increased from about 015a to more than 1a, and the maintenance, repair work and repair costs of the new wheel set have also been greatly reduced. It is estimated that each mining car can save nearly 200 yuan/a of maintenance costs, and change the labor intensity rate of maintenance workers.
