Forming cam during operation, can be clearly seen in the peach at the tip (maximum cam radius) of the cam under attack, the emergence of the phenomenon in the cam pause peach bottom of the (minimum cam radius). These phenomena are the following will be discussed. Now first of all to study the impact of the phenomenon at the peach tip. Based on observation and analysis, it can be appreciated, the impact of this phenomenon is due to the generation of the inverted peach tip change before and after the action of the cam torque direction suffered caused.
When the cam lift its arc acting on the rotor, the rotor cam vertebral move toward the bottom chimney peach peach tip, forcing the ring rail, and so overcome the weight of the yarn guide plate rises at this time of the cam rotor for power, the rotor of cam torque (that is, the torque cam suffered} cam drag torque, which turned to the opposite direction. the rotor is the next peach tip of the cam by turning down lift arc arc, this time lifting member (ring plate, guide yarn board, etc.) due to its own weight decreased, the cam is to control their rate of decline, but definitely not push them. on the contrary, is pushing lifter cam, cam thrust accept them. this will push the cam torque direction of a steering appearance. Thus, the rotor through the peach tip, turned down by the open arc arc occasion, the cam torque generated mutations suffered direction, push the meat into resistance short moment, by the speed and reversing into the same direction, this caused a sudden change in the steering Wu impact sound bigger rotor diameter of some, this can be relaxed -. "sudden change, so that the impact sound is improved, however, as further in-depth research and analysis of the impact of this phenomenon, so we can note z relative to the cam and cam drive is concerned, it is satisfied that a sudden change in the direction of the force is only the external impact, rather than the thing itself internal, then, the phenomenon of internal impact what is it? through careful observation and analysis of this phenomenon can be found in the internal drive is JO gap between the related parts. for example, the street side of the gap between the tooth and the tooth, ingots and ingot ask gap between the grooves, etc., resulting in movement sound or impact force change direction.
