application of crane wheels
The composition of crane wheels: The function of the crane wheel tread is to support the weight of the crane and enable it to operate. According to the different use positions of the wheels and the working conditions on site, crane wheels can be divided into three types according to the rim form: double rim wheels, single rim wheels and rimless wheels. The function of the rim is to guide and prevent the vehicle body from derailing.
The components of the crane wheel group mainly include: wheel body, wheel axle, bearing, bearing box, etc.
Wheel function: Wheel is an important traveling part of crane. It has the functions of bearing weight, moving and guiding, buffering and shock absorption, and maintaining balance. It rubs against the track for a long time and needs to have good wear resistance.
A set of wheel sets includes: 2 sets of driving wheels; 2 sets of passive wheels
Usually, the wheels of large vehicles use double-rim wheels with a height of 25-30mm; the wheels of small vehicles use single-rim wheels with a height of 20-25mm; rimless wheels can only be used in configurations with horizontal guide wheels on both sides of the wheels. Rimless wheels are used to deal with rail-biting situations, but leveling wheels must be used to prevent derailment. The horizontal wheel guide replaces the rim guide, and the sliding friction between the rim and the front of the track is converted into a rolling friction between the level wheel and the front of the track, which reduces the running resistance and increases the life of the wheel.
Crane wheels can be divided into cylindrical, conical and conical drum shapes according to the content of the tread.
Cylindrical wheels are mostly used for driven wheels and can also be used for drive wheels. The conical wheel is used as the driving wheel of the crane.
Conical conical drum wheel tread content is usually 1:10 taper, the installation of the wheel diameter of the end installed in the span inside the positive cone method, so that the operation of perseverance, active straight effect.
The conical drum wheel tread is circular arc, which is mainly used for electric hoist suspension trolley and circular rail crane to remove additional resistance and wear. Cracks appeared at the rim and spoke before the wheel was scrapped.
1. Common materials for cast wheels: ZG45#, ZG55#, ZG50SiMn, ZG50MnMo, ZG42CrMo, etc.
2. Forged wheel materials: 45#, 60#, 40Cr, 65Mn, 42CrMo, etc.
1. Heat treatment method: Heat treatment is divided into surface quenching treatment and overall tempering treatment according to different product styles and usage methods.
2. Advantages of forging process:
3. Dense organization, forging can make metal fibers continuous, mechanical properties are better, strength and toughness are higher.
4. It is relatively easy to produce large wheel sets.
5. Advantages of casting process: Relatively low cost, especially for the manufacture of some complex shapes, it is more economical.
1. Strong load-bearing capacity, able to withstand the huge weight of the crane and the heavy objects it transports, ensuring safe and stable operation.
2. Good wear resistance, can maintain good shape and performance during long-term use, reduce replacement frequency and reduce costs.
3. Smooth operation, making the crane smooth and smooth during movement, helping to ensure the accuracy and safety of lifting operations.
4. Adapt to a variety of working conditions, with a solid and reliable structure, safe and durable
