Spline shaft gear is our life and production, one of the more common shaft, which is composed of three parts by the spline, flat shaft, gears, connected by means of spline points: inside and outside Spline Spline, by type, : rectangle spline and Involute Spline, Spline Shaft power transmission shaft than the other products, because the hole axis with the hub directly and evenly produced more tooth and slot, the joint acceptance more uniform; by shallow groove, the tooth root stress concentration of the small shaft and hub to weaken the strength of less; more teeth, the larger the total contact area, which can withstand greater loads; axis parts with the axis of neutral, and this high-speed and precision machinery is very important; -oriented, and this dynamic linking is very important, also has good gear transmission, the number of teeth because it more closely meshing gears meshing with the gear gap between the small role: The main control of the speed of mechanical operation, as well as mutual energy transfer, the use of the gearbox.
花键齿轮轴是我们生产生活中比较常见轴类之一，它由三部分组成花键、平轴、齿轮，按花键的联接方式分：内花键和外花键，按种类分：矩形花键和渐开线花键，花键轴力的传递性要强于其他轴类产品，因为在轴上与毂孔上直接而均匀地制出较多的齿与槽，故联接受力较为均匀；因槽较浅，齿根处应力集中较小，轴与毂的强度削弱较少；齿数较多，总接触面积较大，因而可承受较大的载荷；轴上零件与轴的对中性好，这对高速及精密机器很重要；导向性好，这对动联接很重要，齿轮也具有良好的传递性，因为它的齿数较多，啮合紧密，齿轮与齿轮之间啮合间隙小，作用：主要控制机械运作的速度以及能量相互的传递，使用于变速箱中。
In response to repetitive strain and inflammation, the synovial l-z joints can fill with fluid and distend, resulting in pain from stretching the joint capsule.71 Distension of the articular recesses can also compress the exiting nerve root in the neural foramen or spinal canal, especially when the foramen is already narrowed by joint hypertrophy and/or osteophytes.
反复的应力与炎症反应，可使滑膜l-z关节充满滑液并扩张，导致关节囊收到牵拉产生疼痛。关节囊隐窝的扩张可以压迫神经孔出的神经根出口或压迫椎管内脊髓，尤其当由于关节肥大和/或骨赘形成已经存在椎间孔狭窄时发生率更高。
