Definitions
- the invention relates to a vertical shaft with a central oil delivery channel with two oil spray points located above shaft bearings and with a section which widens conically from bottom to top and is used for oil production.
- the supply of bearings to high speed shafts is critical. On the one hand, it must be ensured that the oil flow supplied does not stop. On the other hand, the oil must be metered, that is to say supplied to the bearings in very small, just sufficient amounts.
- the object of the present invention is to improve a shaft suitable for vertical use with a central oil feed channel with respect to the lubricant flow.
- this object is achieved in that the conical section extends from the lower end of the shaft to significantly beyond the lower oil spray point. This measure initially ensures that there is sufficient conveying action even above the lower spray point to convey the oil that has not yet been sprayed off to the second oil spray point.
- the lower oil spray point is expediently located approximately at the center of the conical section of the oil delivery channel. It is also advantageous if this spraying point comprises only two spraying bores, for example opposite one another. Such an embodiment has the advantage that only the partial quantity which is branched off in the region of the lower spray point is decisive for the quantity distribution of the oil (bottom-top). The oil can continue to rise unhindered between the bores and is also able to get to the upper spray point through the delivery mechanism that is still sufficiently available below. Further advantages and details of the invention will be explained with reference to an embodiment shown in the figure.
- the shaft with 1 its central, bottom open oil delivery channel with 2, the conical section of the delivery channel 2 with 3, the lower oil spray point with 4, the lower bearing with 5 and the oil sump generally with 6.
- the oil level in the oil sump 6 is indicated by line 7.
- the oil sump 6 comprises a central sleeve 8 which is supported on the base plate 9 and into which the lower end of the shaft 1 projects. Via vertical bores 11 and a chamber 12, the oil passes through a further central bore 13 into the sleeve 8. Inside the bore 13 there is an insert 14 with a throttle bore 15. This determines the flow into the sleeve 8 per unit of time Amount of oil.
- the conical section 3 of the delivery channel 2 extends far beyond the lower spray point 4. This comprises only two oil spray bores 16, 17, so that there are conical wall areas - between the bores 16, 17 - on which the further rise of oil is not hindered, and secondly bores with a relatively large diameter that is not sensitive to contamination can be provided.
- the conical section 3 is part of a separate component 21 which is inserted from below into a bore 22 of the shaft 1 which is enlarged relative to the cylindrical section of the oil delivery channel 2.
- the component 21 is not completely inserted into the bore 22, so that a groove 23 is located above the conical section 3.
- This groove 23 has the function of a centrifugal filter. During operation, the groove 23 is filled with oil and, if necessary, picks up particles carried up to this point.
- Centrifugal filters of this or a similar type can also be present at several locations in the central oil production channel 2.
