aa 儀器工作原理 aa 利用一個與齒廓相切的測量面以 及一沿齒面擺動的測量觸頭量得最小距離從而反映出基節偏差值。
Operating principle By way of a measuring face tageut with flauk profile and a measuring contact jigging along the tooth facem the minimun distance can be measured to show the batpitch deviation.
This tester is suitable to measuring the bapitch deviation of straight and helical circular gear, the accuracy value has been indicated. This tester is available to meter rooms and workshops with compact structure, simple and easy operation.
