offset cam
解釋
偏心凸輪-
On the base of keeping the same law of motion of original thread - taking - up pole of computerized embroidery machine and relevant sizes, the cam mechanism with offset flat - bottomed follower is adopted and a new thread - taking - up mechanism is designed
摘要在保持原有電腦刺繡機挑線桿運動規律和相關尺寸不變的基礎上，採用偏置平底推桿盤形凸輪機構，對原挑線機構進行了創新設計。 -
Profile design of cam with cylindrical roller - followers by offset surfaces method
圓柱滾子從動件凸輪廓面的等距曲面設計方法 -
The software can design many conventional type of cam, concluding cam - plate with middle follower, cam - plate with offset follower, cylindrical cam, dividing cylindrical cam, and cylindrical cam with space curve, etc. in forming working curves of cam - plate, used the approximation by arcs which can lessen the nodal points on curves of cam uttermostly in same error, so it reduce the computation time and relieve the chattering of principal axis. in former times, to cam mechanism, the follower only has one direction motion
本軟體可以設計的凸輪類型較多，包括了對心移動從動件盤形凸輪、偏置移動從動件盤形凸輪、圓柱凸輪、圓柱分度凸輪和空間曲線柱形凸輪等，其中對盤形凸輪的工作曲線採用了難度較大的圓弧逼近演算法和等誤差演算法，這樣就可以在相同的允許誤差內最大限度的減少生成曲線的節點數，減少計算時間，同時可以大大減輕加工中的振動現象。
