【正文】 choose the vmax value smaller movement rule. 2) amax bigger, is bigger. Function in high vice contact place stress bigger, the anization intensity and the wear resistant request is also higher. Regarding high speed cam, in order to reduce the harm, should choose the amax value smaller movement rule. First states several kind of movements rules vmax, amax, the impact characteristic and the suitable situation following table regarding swings from the cam gear, its movement graph xcoordinate expression cam corner, ycoordinate then separately expresses from, angular speed and angle acceleration. This kind of movement graph has the state of motion and above is same. From structural design: from structure: When design must consider from the guidance and prevented revolves. From movement rule design: The cam gear design basic question 1. cam gears type choice, the definite cam shape, with from maintains the high vice contact from the shape and the movement form and the cam the way 2. from the movement rule design, according to the application situation to from the travelling schedule and the state of motion request, determines from the movement rule. 3. cam gears basic parameter design, determines from the travelling schedule, various movements angle, the cam radius, , the roller radius, the center distance, from the length and so on. 4. cam contours curve design. 5. cam gears bearing capacity putation. 6. cam gears structural design, plan anization assembly drawing and various ponents shop drawing Fromstructural design: from structure: When design must consider from the guidance and prevented revolves. From movement rule design: The cam gear design basic question 1. cam gears type choice, the definite cam shape, with from maintains the high vice contact from the shape and the movement form and the cam the way 2. from the movement rule design, according to the application situation to fromthe travelling schedule and the movement 1, the cam gear application cam gear is includes the cam the high vice anization, the cam gear has the structure to be simple, may accurately realize request merit and so on movement rule, thus obtains the widespread application in the industrial production, specially automatic device and in the automatic control device, obtains the widespread application. 2nd, the cam gear classification according to two moves the relative motion characteristic classification between the ponent (1) the plane cam gear 1) the disk cam。 2) translation cam. (2) space cam gear according to from movement vice element shape classification (1) apex from。the groove in the periphery of the cam should be shaped to acmodate the type of cam is expensive to cylindrical cam has two outstanding is the fact that the cam is positive outside forces (such as gravity or spring action ) are needed to hold the follower against the working surface of the second feature is the fact that the follower can move through a ple
