Abstract
Description
Technical Field
[0001] The utility model relates to a gear reduction gearbox mechanism on a high-speed double-twisting machine, and specifically discloses an uninterrupted oil-spraying lubrication reduction gearbox mechanism. Background Art
[0002] At present, the internal structure of the reduction gearbox on the conventional double twist machine is as follows Figure 1 As shown, the worm 2 is rotatably installed in the reduction gear box 1, an output shaft 3 is rotatably installed in the reduction gear box 1 above the worm 2, a worm wheel 4 is fixed on the output shaft 3, the left end of the output shaft 3 is installed in the inner ring of the left output shaft bearing 5, the right end of the output shaft 3 is installed in the inner ring of the right output shaft gear 6, and half of the worm 2 is immersed in the gear lubricating oil 11.
[0003] During operation, the worm 2 will stir the gear lubricating oil 11 when it rotates. The worm 2 drives the output shaft 3 to rotate through the worm wheel 4. A small amount of gear lubricating oil 11 will flow to the left output shaft bearing 5 and the right output shaft gear 6 along the worm 2, the worm wheel 4 and the output shaft 3 in sequence. The gear lubricating oil 11 driven by the rotation of the worm 2 cannot fully lubricate the left output shaft bearing 5 and the right output shaft gear 6. When the worm 2 rotates at a high speed (450-750 rpm), the worm 2 will cause the gear lubricating oil 11 to shake violently. The violently shaking gear lubricating oil 11 will splash onto the left output shaft bearing 5 and the right output shaft gear 6, playing a role in fully lubricating the left output shaft bearing 5 and the right output shaft gear 6. When the worm 2 rotates at a low speed (less than 300 rpm), the worm 2 cannot cause the gear lubricating oil 11 to shake violently, and the gear lubricating oil 11 will not splash onto the left output shaft bearing 5 and the right output shaft gear 6, thereby causing the left output shaft bearing 5 and the right output shaft gear 6 to be damaged due to lack of oil.
