Definitions

  • the object of the invention is to provide a device which can be built into for instance the motor vehicle and enables a regular lubrication without standstill or servicing being necessary therefor.
  • the invention provides a device for transporting medium, for instance oil, grease or other lubricant from a medium supply to a receiving station movable rotatably relative thereto, which device comprises: a medium supply,* and a collecting member disposed in stationary position relative to the receiving station and having an internal space which is accessible from outside and in the periph ⁇ eral wall of which a substantially annular groove is present, which medium supply is adapted and placed for deliv ⁇ ering medium into the groove, to which groove connects a medium pump for drawing out of the groove and transporting medium to the receiv- ing station.
  • the trans ⁇ port of cooling water or even a gaseous medium also lies within the scope of the invention.
  • the device according to the invention is embodied in open form, i.e. such that the use of seals can in princi ⁇ ple be dispensed with.
  • the construction can hereby be very simple and reliable.
  • the device according to the invention can transport the relevant medium without leakage.
  • An additional advantage of the absence of seals is the low energy loss due to the absence of mutually rubbing surfaces.
  • the medium supply can for instance be adapted and placed for delivering a continuous flow or measured quantities of medium to the groove through the force of gravity.
  • the groove which generally rotates in absolute sense relative to the stationary medium supply, serves to collect and buffer a certain quantity of medium for transporting.
  • An embodiment in which the groove is eccentric and the pump connects onto the groove in the zone radially furthest to the outside has the advantage that due to the centrifugal forces occurring during rotation the medium collects in the zone most remote from the rotation axis . The medium can be drawn off from this position by the pump for further transport.
  • a specific embodiment has the special feature that the pump is actuated by contact means with an actuating member present on the pump which co-acts with a contact member movable relative to the actuating member for actuating the pump. With such an embodiment the pump can be operated as required or in accordance with the wishes of the user.
  • the pump is actuated by contact means with an actuating member present on the pump which co-acts with a contact member which is sta- tionary relative to the medium source such that at each relative rotation the pump performs a pumping stroke.
  • This embodiment can be suitable for instance for slow- running systems.
  • actuating means responding to centrifugal force.
  • actuating means can for instance be embodied as a spring-loaded plunger which in per se known manner feeds medium via a first non-return valve and discharges medium via a second non-return valve.
  • Such a pump then only provides a pumping stroke when a determined speed of rotation is exceeded.
  • the advantage of this embodiment is therefore that the desired very small dosage can general ⁇ ly be realized more easily and there is no longer a contact member subject to wear.
  • the determining parame ⁇ ters such as the relevant plunger diameter, the spring constant of the spring means etc.
  • Cardan shafts for trucks, buses and other means of transport such as agricultural machines are used here to lubricate universal joints, bearings and the like with oil or grease.
  • Marine propellers universal joint.
  • Machines having for instance high-speed spindles which are equipped with tools provided with internal cooling channels.
  • the medium can be an oil, an emulsion or other coolant or lubricant.
  • the device according to the invention is very suit ⁇ able for lubricating parts or components on the end zones of rotating shafts to which there is no access or access is difficult.
  • the invention can also be applied success ⁇ fully with rotating shafts of very great length on which are arranged objects for lubricating.
  • Figure 1 shows a broken away perspective view of a rotating shaft with two cardan joints and a device ac- cording to the invention
  • Figure 2 shows partly in side view and partly in cross section a first embodiment of the device according to the invention
  • Figure 3 is a partly broken away perspective view of a second embodiment
  • Figure 4 is a view corresponding with figure 2 of a third embodiment
  • Figure 5 shows partly in side view and partly in perspective view a fourth embodiment
  • Figure 6 is a view corresponding with figure 5 of a fifth embodiment.
  • FIG 1 shows a shaft 1 driven by means which are not shown and provided on its ends with universal joints 2, 3 for coupling to respective other shafts.
  • Shaft 1 bears a device 4 according to the invention.
  • This device serves to transport a lubricant from a storage container 5, via a feed conduit 6 and discharge conduits 7, 8 to the universal joints 2 and 3.
  • the storage container 5 is disposed in stationary position relative to shaft 1 and universal joints 2, 3.
  • the device 4 is adapted in the manner to be described hereinafter to supply lubricant such as oil or grease from the stationary storage con ⁇ tainer 5 and the feed conduit 6 to the rotating universal joints 2, 3.
  • Figure 2 shows that the shaft is provided on its peripheral surface with a ring 9 with conical screw thread 10.
  • a device 11 according to the invention is screwed onto this conical screw thread.
  • the device 11 comprises an annular block 12 which is coupled rotatably via a bearing 13 to a stationary thro- ughfeed ring 14. Via a seal 15 and a labyrinth 16 the throughfeed ring 14 and the annular block 12 are mutually joined in substantially dust-tight manner.
  • the throughfeed ring 14 extends in an annular space 17 present in annular block 12, in the outer wall 18 of which space are arranged two annular grooves 19 and 20 respectively. As the figure shows, these grooves are placed eccentrically, this such that their deepest zone, i.e. that located radially furthest to the outside, connects onto an associated medium discharge conduit 21, 22. Via feed conduit 6 medium, in particular lubricant, is transported downward via respective feeds 23, 24 and there collected in the respective grooves 19, 10. This lubricant is then transported via discharge conduits 21, 22 to associated pumps 123, 124. These pumps transport the lubricant via discharge conduits 7, 8 to the univer ⁇ sal joints 2, 3.
  • the pumps 123 and 124 are identical. A short de ⁇ scription will therefore be limited to pump 123, which can otherwise be of any suitable type.
  • a weight 25 is guided slidably in radial direction and can thus displace a sealing ball 26.
  • the force of gravity pulls the weight 25 downward and ball 26 is situated in its shown lowest position.
  • the force of gravity pulls the weight 25 to the position radially furthest to the outside, carrying with it the ball 26.
  • the ball 26 is again carried along by the weight 25 to the upper position shown in figure 2.
  • a second ball 27 co-acts with a seat 28 and is loaded by a pressure spring 29. This structure forms a non-return valve.
  • the balls 26, 27 which are arranged in a throughfeed conduit 30 form a one-way pump which can pump the lubricant out of the groove 19 via the medium discharge conduit 21 and throughfeed conduit 30 to discharge conduit 27.
  • the drawn embodiment makes use of the force of gravity to actuate the pumps 123, 124.
  • the sealing ball 26 can also be spring-loaded, if desired in combination with a weight, such that the pumping action is obtained when the rotation speed is varied, wherein at certain times the rotation speed is exceeded, wherein the total movable mass undergoes a centrifugal force such that it urges the ball to the position located furthest to the outside counter to the action of the associated spring means .
  • FIG. 3 shows a device 31 which, other than the device 11 according to figure 2, comprises three grooves 19, 20, 32.
  • the groove 32 co-acts with a pump 33 which transports lubricant via a discharge conduit 34 to a receiving station.
  • Figure 4 shows a device 35 according to the inven ⁇ tion in another embodiment.
  • the thro ⁇ ughfeed ring 36 which corresponds functionally with throughfeed ring 14 according to figure 2, carries rise cams 37, 38 which, on rotation of the shaft 1 and thus the annular block 12, actuate a radially outward directed displacement of a pin 39, which is urged radially inward by spring means (not drawn) , and thus the ball 26.
  • a forced control of ball 26 is realized in this manner.
  • the structure of the pumps 40, 41 according to figure 4 is otherwise the same as that of pumps 123, 124 according to figure 2.
  • Figure 5 shows a device 42, wherein a throughfeed ring 43 of fibrous material such as felt is applied. This is held in position by a self-tapping screw 44 supported by a support 45.
  • Figure 6 shows a device 46 which corresponds sub ⁇ stantially with the device 35 according to figure 4.
  • a throughfeed ring 47 serves to feed lubricant to the grooves 19, 20. It can be seen from figure 6 that the feed conduit 6 is placed relatively close to the dis ⁇ charge conduit 8. In the embodiment of figure 4 this distance is greater.
