Are dog clutch teeth supposed usually to have 90 degree flanks, or are they sometimes inclined like an acme thread?
I have a power guillotine (4 foot x 1.6mm cut) that spins a flywheel with a
1.1kw motor, and pressing the treadle allows a dog clutch to engage via spring pressure rotating eccentrics which pull the upper blade through the material. Recently under full width cuts the clutch has taken to not fully engaging, and jumping out of engagement. The flanks are obviously fairly worn and need re-machining, but what shape to make them - they could have been inclined or this could be the wear with them starting off perpendicular - any suggestions?AWEM
