The reducer coupling is a key component connecting the reducer output shaft and the working machine input shaft. It is mainly used to transmit torque, compensate for the relative displacement of the two axes, and buffer shock absorption. The following is an introduction to the key points of the selection of reducer couplings:
Torque transmission: Select a coupling that can withstand the corresponding torque based on the rated output torque of the reducer and the input torque required by the working machine. Generally, the allowable torque of the coupling is greater than or equal to 1.2 - 1.5 times the actual transmitted torque.
Displacement compensation: Considering the possible errors during installation of reducer and working machine and the relative displacement of the two axes during working process, select a coupling with appropriate displacement compensation capabilities. For example, for equipment with low installation accuracy or large vibration, couplings that can compensate for large displacement should be selected.
Speed requirements: The allowable speed of the coupling should be higher than the actual speed of the reducer and working machine. Especially in high-speed transmission, attention should be paid to the balance accuracy and critical speed of the coupling to avoid vibration and noise caused by excessive speed, and even affecting the normal operation of the equipment.
Working environment: Choose the appropriate coupling according to the different working environment. If in high temperature environments, high temperature-resistant materials and structural forms should be selected; in environments with corrosive media, corrosion-resistant couplings should be selected; in flammable and explosive environments, couplings with explosion-proof performance should be selected.
Installation and Maintenance: Choose a coupling that is easy to install and easy to maintain, which can reduce the installation and maintenance costs of the equipment. At the same time, it is necessary to consider whether the coupling is convenient to disassemble and replace, so that it can operate quickly during equipment maintenance.
