The coupling of an electric flatcar is a critical component, which is very important for electric flatcars. So, how to choose the appropriate coupling?
Firstly, we should know that when choosing a suitable electric flatbed coupling, various characteristics of the coupling should be taken into account, such as the required height of the transmission shaft, the size of the load, the installation accuracy of the two parts, the connection, and smooth rotation. Gender, price, etc. When making specific choices, the following points should be considered:
1. Manufacturing, installation, maintenance, and cost of couplings.
On the premise of meeting the performance requirements of electric flatcars, couplings that are easy to disassemble, maintain, and cost-effective should be selected as much as possible. For example, rigid couplings are not only structurally simple, but also easy to assemble and disassemble, and can be used for low-speed rigid drive shafts. Commonly used as flange couplings. Another example is non-metallic elastic component couplings (such as elastic sleeve pin couplings, elastic pin couplings, plum blossom elastic couplings, etc.), which are also cheaper.
2. The magnitude and nature of the torque to be transmitted, as well as the requirements for buffering vibration function. For high-power heavy-duty transmissions, gear couplings can be used. For transmissions with heavy impact loads or requiring shaft torsional vibration, tire type couplings can be used.
3. The installation accuracy of the two connected components.
When the radial displacement is large, an optional slider coupling can be used; Joints with large angular displacement or intersecting axes can be used in conjunction with universal couplings. When two shafts experience significant additional relative displacement during operation, please use a flexible coupling. This is caused by manufacturing, installation, load deformation, and temperature changes. After the installation and debugging of the electric flat car, the two axes cannot be accurately aligned, and there is a certain degree of displacement in the x and Y directions as well as the deflection angle CI.
3. The working speed and centrifugal force generated by the electric flat car coupling. For high-speed transmission shafts, couplings with high balance accuracy, such as diaphragm couplings, should be used instead of eccentric slider couplings.
4. Reliability and working environment of electric flat car couplings.
Couplings typically made of metal components that do not require lubrication are relatively reliable. Couplings that require lubrication are easily affected by the degree of lubrication and may contaminate the environment. Couplings containing non-metallic components such as rubber are sensitive to temperature, corrosive media, and strong light, and are prone to aging.
