<p>The invention provides a machine oil discharge structure of a speed transmission. Machine oil stored in a second chamber of a casing of the speed transmission is discharged smoothly towards a first chamber, which reduces machine oil stirring resistance generated by a rotation body disposed in a second chamber and decreases the mixing of bubbles in the machine oil. A first wall face of the second chamber, opposite to the outer circumference of the lower part of the first rotation body, is provided with a first rib protruding towards the outer circumference of the first rotation body. A separation wall which is adjacent to the lagging side of the first rotation body and faces the first rib is provided with a first communication hole. A separation wall which is adjacent to the advancing side of the first rotation body and faces the first rib is provided with a second communication hole. The machine oil scattering from the outer circumference of the first rotation body to the advancing side of the rotation direction and machine oil facing the first wall face of the second chamber and flowing from the lagging side of the rotation direction are shielded by the first rib without front collision. Bubble generation can be prevented due to the stirring of machine oil, and machine oil captures from two sides of the first rib are respectively and smoothly discharged through the first and second communication holes towards the first chamber.</p> |
