The observation cover 6 may also be made of a transparent resin material, and is disposed on the sub-tank 3 by an in-line manner.
在本实施例中, 子箱体 3开设有安装温度传感器的开孔 7, 需要测量子箱 体 3内部的轴承 9与轴承 10温度的温度传感器***开孔 7。 In the present embodiment, the sub-tank 3 is provided with an opening 7 for mounting a temperature sensor, and a temperature sensor for measuring the temperature of the bearing 9 inside the sub-tank 3 and the bearing 10 is inserted into the opening 7.
在本实施例中的子箱体 3上设置有油孔 8, 方便随时向机体内部的轴承和 齿轮部分进行润滑与冷却。 The sub-tank 3 in the present embodiment is provided with an oil hole 8, which facilitates lubrication and cooling of the bearing and the gear portion inside the body at any time.
在本实施例中,输出轴 2两端的输出轴轴 7 部分选用不同的结构。输出轴 2一端安装的输出轴轴承为圓柱滚子轴承 9; 另一端安装的输出轴轴承为两个 对装的圓锥滚子轴承 10, 两个对装的圓锥滚子轴承中间设置有顶住对装的圓 锥滚子轴承外圏的村圏 11 , 两个对装的圓锥滚子轴承 10外圏分别与村圏 11 相抵。 当内部温度上升时, 输出轴 2的轴向长度发生轻微变化, 通过圓柱滚子 轴承 9的内圏与外圏不发生相对分离的轴向移动,调整与输出轴 2的相对位置, 适应输出轴 2轴向长度的变化,从而有效的避免了因内部升温使输出轴 2轴向 增长致使其弯曲的情况发生。
在输出轴 2输出端还套设有挡油盘、 密封圏和有孔端盖, 将有孔端盖与子 箱体 3通过螺栓连接完成子箱体部件的装配。 In the present embodiment, the output shaft shaft 7 at both ends of the output shaft 2 is selected to have a different structure. The output shaft bearing installed at one end of the output shaft 2 is a cylindrical roller bearing 9; the output shaft bearing mounted at the other end is two pairs of tapered roller bearings 10, and the top of the two pairs of tapered roller bearings are provided with a top The village 圏11 of the outer tapered roller bearing is installed, and the two outer cylindrical roller bearings 10 are respectively opposite to the village 圏11. When the internal temperature rises, the axial length of the output shaft 2 slightly changes, and the relative movement of the inner shaft and the outer bore of the cylindrical roller bearing 9 does not occur, and the relative position of the output shaft 2 is adjusted to accommodate the output shaft. 2 The change of the axial length effectively avoids the occurrence of bending due to the axial increase of the output shaft 2 due to the internal temperature rise. At the output end of the output shaft 2, an oil retaining plate, a sealing cymbal and a perforated end cover are also sleeved, and the perforated end cover and the sub-tank 3 are bolted to complete the assembly of the sub-tank parts.
为了提高输出轴 2的密封性能,输出轴 2上套设的密封圏与有孔端盖形成 了迷宫式密封结构, 有效的降低了油泄漏量。 也可以将密封圏设置为迷宫式密 封圏, 同样达到降低油泄漏量的作用。 In order to improve the sealing performance of the output shaft 2, the sealing ferrule and the perforated end cover of the output shaft 2 form a labyrinth seal structure, which effectively reduces the amount of oil leakage. It is also possible to set the sealing jaw to a labyrinth seal, which also reduces the amount of oil leakage.
为了减少输出轴 2转动时与有孔端盖的孔壁摩擦,本实施例中的有孔端盖 孔径大于输出轴 2相应位置的轴径, 在输出轴 2相应位置设置沟槽, 通过与沟 槽配合安装锁紧垫片与锁紧螺母达到轴端锁紧的作用。 In order to reduce the friction between the output shaft 2 and the hole wall of the perforated end cover, the aperture end cover aperture in this embodiment is larger than the corresponding shaft diameter of the output shaft 2, and the groove is provided at the corresponding position of the output shaft 2, through the groove. The groove fits the locking washer and the lock nut to achieve the locking of the shaft end.
