The low voltage transfer trolleys are key components and are critical for low voltage electric transfer trolleys, so how to choose the right coupling is a crucial step. Let's see how to choose:

First of all, we should know that the selection of suitable low voltage transfer trolleys should refer to the various characteristics of the coupling, namely: the height of the required transmission shaft, the size of the load, the installation accuracy of the two parts being connected, and the rotation. Smooth, price, etc. The following points can be considered when making specific choices:

1. Manufacturing, installation, maintenance and cost of the coupling.

Under the premise of satisfying the performance of low voltage transfer trolleys, the couplings with convenient assembly and disassembly, simple maintenance and low cost should be selected. For example, the rigid coupling is not only simple in structure, but also convenient to assemble and disassemble, and can be used for a low-speed, rigid drive shaft. Commonly used as flange couplings. Another example is the non-metallic elastic component coupling (such as elastic sleeve pin coupling, elastic pin coupling, plum-shaped elastic coupling, etc.), which is also cheaper.

2. The magnitude and nature of the torque to be transmitted and the requirements for the buffer vibration function. For high-power heavy-duty transmissions, gear couplings are available; for heavy-impact loads or for transmissions that require shafting torsional vibration, a tire-type coupling is available.

3. Installation accuracy of the two parts being connected.

When the radial displacement is large, the optional slider coupling can be used; the joint with large angular displacement or intersecting two shafts can be used with universal coupling; when the two shafts produce large additional relative displacement during operation, Use a flexible coupling. This is due to manufacturing, installation, load deformation and temperature changes. After the electric flat car is installed and adjusted, the two axes cannot be strictly aligned accurately, and there is a certain degree of displacement in the x and Y directions and the skew angle CI.

4, low voltage rail powered transfer trolleys the working speed of the coupling and the amount of centrifugal force caused. For high-speed transmission shafts, couplings with high balance accuracy, such as diaphragm couplings, should be used, and eccentric slider couplings should not be used.

5, low voltage rail operated transfer trolleys accessories coupling reliability and working environment.

Couplings that are usually made of metal components that do not require lubrication are relatively reliable; couplings that require lubrication are susceptible to the degree of lubrication and may pollute the environment. Couplings containing non-metallic components such as rubber are sensitive to temperature, corrosive media, and strong light, and are prone to aging.
