Strength Analysis of Forging Magnesium
Forged magnesium wheels are one of the basic components of the vehicle running on the track. Although the excellent bogie can improve the wheel and rail power, the heavy load must increase the force of the wheel, which is not only related to the safe operation of the vehicle , But also involves the capacity of the line, from the axle to reduce the heavy load speed wheel wheel wheel force is a very important issue. Heavy load speed wheel to withstand large static, dynamic mechanical load and brake thermal load, must have a very high strength and safety and reliability, must also meet the reliability on the basis of minimizing the weight (reed quality). Reducing the quality of the wheel can also increase the truck's load under the maximum axle load allowed by the line.
Forging magnesium wheel strength is in accordance with the thickness of the rim to the size of the design, the original thickness of the rim and wear life and cost. For the weight loss, can reduce the thickness of the rim shape, the use of thin rim rim wheels; by optimizing the design, looking for better carrying capacity of the web shape, so that the same weight can withstand greater load, to achieve the purpose of weight loss; To ensure that the axle assembly firmly under the premise of reducing the hub thickness.
Forged magnesium wheel is an important part of the crane, when the problem, we need to be replaced, then we need to how to operate it? The following by Xiaobian summarized for you:
First, remove the connecting bolts of the shaft end coupling of the wheel; then remove the fastening bolts connected to the endlugs of the forged magnets and the end girders. Take the jacks or jacks of the cranes to lift the cranes. Tread from the top of the track about lOmm or so, leveraging forged magnesium and pull it out along the track to remove the replacement;
Then take the pre-assembled, new and with the shaft end gear coupling half of the active forging magnesium wheel to the crane track, in order to ensure safety should be pushed into the forged magnesium wheel near the installation location, adjust the jack to the car Body slow down, penetrate the fastening bolts, screw on the nut;
Appropriate tightening of the horizontal bolts, and then tighten the corresponding vertical bolts, alternating into the Ding, while fastening the wheel, check the wheel rotation is flexible, and check the wheel installation of the horizontal and vertical skew.
Aligning the wheel shaft end gear coupling half and the reducer slave shaft coupling half of the screw hole, penetrate the connecting bolt and fasten. After all normal, the body will fall.
