A　new　method　was　put　forward　to　measure　the　errors　of　bevel　gear　and　corresponding　measure　device　was　invented.　The　measure　gear　was　made　by　pasting　the　metal　silks　on　the　teeth.　The　advantage　of　the　device　was　the　error　(including　tangential　composite　error,　tangential　tooth-to-tooth　composite　error,　radial　composite　error,　total　cumulative　pitch　error　and　total　alignment　error　et　al)　can　be　measured　by　the　measure　gear.　The　measure　gear　can　be　made　conveniently.　The　error　caused　by　the　pasted　metal　silk　was　assessed.　Also　the　three　dimension　model　of　the　measured　gear　can　be　founded　by　the　errors　measured　by　the　device.　The　model　contains　all　the　error　information　of　the　measured　gear.　©　2009　IEEE.
