Precautions for selecting cross shaft universal coupling for melt gear pump

The torque between the melt gear pump and the motor is transmitted through a cross shaft universal coupling. Due to its large angle compensation ability, the cross shaft universal coupling has a compact structure, smooth operation without noise, strong load-bearing capacity, and a torque of over 6000KN · M. It is widely used for high-power transmission with obvious energy-saving effects. When selecting a cross shaft universal coupling for polymer melt conveying gear pumps, the following points need to be noted.

1. It is necessary to clarify the size and category of the transmitted load: whether it is a unidirectional constant load, pulsating load, or a bidirectional alternating load, and the specific operating conditions coefficient;

2. Working environment: whether there are adverse environmental conditions such as high temperature, dust, water immersion, chemical corrosion, and short maintenance cycles;

3. On site installation conditions: Are there any restrictions on the installation location and the specific installation length;

4. What is the rotational speed of the universal joint itself and whether dynamic balancing is required.
