Why Do Engineers

Why Do Engineers Around Two Gears Making The Gears Thicker See This Thing Coupling Long Time Engineers Preferred Flexible Couplings The Orange Part Works Like A Soft Mechanical Joint When The Machine Starts The Motor Creates A Sudden Instead Of Sending That Shock Directly Shaft The Rubber Twists Slightly And Absorbs The Impact Two Shafts Are Slightly Misaligned Deform And Take That Error The Result Is The Bearings And A Smoother Quieter Machine Sounds Perfect Right But The Fatal It Can't Fit Into A Smaller Space Moreover Rubber Is Thicker Will The Buffering Space Be Larger Here The Environment Is Closed High And The Torque Is Extremely Large Will Cause The Rubber To Break Won'T When The Chain Rollers Transfers The Motion Hub That Tiny Amount Of Movement Inside Can Absorb Small Alignment Errors And Startup Shocks Very Small Space It Can Still Handle High Torque While Keeping Some Clever Part Of A Chain Coupling Strong Enough To Flexible Enough To Survive Real Machines
