    Tips: How to install the ATO 63mm worm gearbox?

    • The installation relationship between the 63mm worm gear motor and the working machine. In order to avoid the deflection of the main shaft of the working machine and the generation of additional force on the bearing of the reducer, the distance between the 63mm worm gearbox and the working machine should be as small as possible, 5-10mm, without affecting normal operation.
    • The connection between the shaft-mounted worm gear motor and the working machine. The 63mm worm gearbox speed reducer is directly sleeved on the main shaft of the working machine. When the reducer is running, the reaction torque acting on the reducer case body is balanced by the reaction torque bracket installed on the reducer case body or by other methods.
    • Installation of the anti-moment bracket. The counter-moment support should be installed on the side of the working machine facing the reducer to reduce the bending moment attached to the working machine shaft. The counter-torque bracket and the shaft sleeve of the fixed supporting connection end use rubber and other elastic bodies to prevent flexure and absorb the generated torque fluctuations.
