The performance of the worm reducer depends on correct installation, lubrication, and maintenance. There are two common mounting methods:
Ensure that the shaft and the gear unit hole for mounting the gear unit are clean and free from burrs. Apply a sufficient amount of lubricating oil to the shaft and hole to aid assembly and prevent friction corrosion. Slide the unit onto the drive shaft and secure with a key.
Mount the unit securely on a sturdy structure. Install an output shaft extension if required. The connection between shafts should use an elastic coupling, ensuring that the shaft misalignment is within the coupling's tolerance. When mounting pulleys or sprockets on two shafts, place them as close as possible to the gearbox. Do not strike the shafts when installing or removing the transmission components, as this may damage the bearings.
