About installation
Follow the instruction and note below to accurate installation of Mecha-lock.
Use the torque wrench for tightening screws.
Cleaning of Mecha-lock installation surface.
Wipe and clean the dust, rust and oil on shaft surface.
For normal application
Oil is unnecessary on shaft. Assemble as it is.
Note for clean circumstance application
·Circumstances is vacuumed.
- Application of dry condition.
Torque capacity on catalogue will be the same without oil is on shaft. - Application of using vacuum grease.
This grease may cause of shaft slipping or increasing the tightening toque, which over the yield point. Therefore we recommend of evaluation test.
Special screw (plating type) is required for vacuum or clean room circumstances. Ask us for the application.
Note for the hub installation.
After the installation of Mecha-lock to shaft, and insert to the hub, which processed in selected dimension. Confirm the hub edge perfectly attached to flange (Fig.1). Confirm the depth by depth gage or caliper if it is difficult to judge by sight.
Use plastic hammer to hit lightly if installation is hard.
Use plastic hammer to hit lightly if installation is hard.
If there is a gap at connection, Mecha-lock flange may be deformed.
Note for shaft installation.
The inner ring taper and outer ring taper are stacking together by transportation and hard to insert the shaft and hub, loose the locking screws and disassemble the taper pats of Mecha-lock by using uninstallation screw.
Tightening the screws after positioning.
Tighten gently in diagonal direction by torque wrench (about 1/4 of tightening torque), next increase the tightening force (half torque of tightening torque), and finally tightening all screws in circle direction. Confirm that all screws does not rotate after tightening in. Also confirm the tightening torque is right for all screws. (table below) (Fig.2)
Uninstallation
Check your safety first before starting an uninstall operation.
Turn off the power and check thrust load or torque are not on Mecha-lock or check the drops.
Loosen the screws in order gently.
Install those loosen screws in to uninstallation hole and tightening evenly for taking parts.(Fig.3)
Use all uninstallation holes and tighten several times, otherwise flange part will be deformed and hard to reuse this again.
