Gimbal
Gimbal frame
Bearings
Prepare them as the first step. You will get three bearings with long bolts and two bearings with short bolts.
Tighten it thoroughly!
Gimbal frame side
Prepare four frame sides:
- two with longer bolts.
- two with shorter bolts.
Note which side round bearing block goes with relation to nuts and screw heads!
Gimbal stick connector
Assembly gimbal stick arm.
Note which side round bearing block goes with relation to nuts and screw heads!
Roll axis frame
Use two frame sides with shorter bolts for roll axis frame.
Install longer bolts to frame cores as it will not be possible to install them later. Fix one with coupling tube and tighten it, and one with a nut.
Start assembly from frame side:
- Install arm lever on it and tighten M8 nut fixing it.
- Install frame cores into corresponding slots.
- Install second frame side, and tighten M8 nut fixing it.
Note how frame sides oriented to the mowing gimbal arm!
Fix gimbal sides to gimbal cores using nut in slot and tightening screws.
Install pulley onto the frame:
- unscrew temporary M8 nut.
- install spacers 6mm in total.
- install pulley.
- fix with M6 bolts and M8 nut.
Pitch axis frame
Most of the process is close to roll axis assembly:
- prepare frame cores with longer bolts.
- fixing central core to the side.
- install frame cores to the slots.
- install second side.
- fix everything with nuts and screws.
- install pulley.
- tighten all screws and nuts thoroughly!
