6136车床挂轮架的三星齿轮变向机构,原设计是靠松紧锁紧螺母,调整三星齿轮与主轴齿轮啮合以实行变向的(见图),实际操作中存在以下的病。 1.使用中靠松紧锁紧螺母,搬动手柄调整变向机构,操作不方便,凭经验掌握啮合间隙,易产生啮合过松或过紧现象。过紧:显引起啮合激烈撞击、卡死,造成齿轮打齿,挂轮架损坏等现象;过松:齿轮易过早磨损,产生齿顶变尖,噪音增大等现象。
6136 Lathe rack Samsung gear steering mechanism, the original design is by tight locking nut, adjust the Samsung gear meshing with the mainshaft to implement the change direction (see photo), the actual operation of the following diseases. 1. The use of elastic locking nut, moving the handle to adjust the steering mechanism, the operation is not convenient, grasp the engagement gap by experience, easy to produce too loose or too tight engagement phenomenon. Too tight: obviously caused by the engagement of a strong impact, stuck, resulting in gear teeth, hanging rack damage and other phenomena; too loose: gear premature wear, resulting in tooth tip sharpening, noise and so on.
