Definitions
- Sealing system for gear pumps for highly viscous rubber, polymer materials and other products to be demanded.
- the invention relates to a sealing system according to the preamble of claim 1.
- Rolling bearings are known and used in feed pumps as well as in gear pumps, the feed medium generally also being used to lubricate the bearings, e.g. Hydraulic oils, process oils.
- Hydraulic oils e.g. Hydraulic oils, process oils.
- attempts are made to achieve a seal against the medium to be conveyed using elastic seals and other sealing systems.
- the object is thereby achieved the features of claim 1.
- the deflection is arranged by the roller bearing arrangement directly next to the gear body.
- a support bearing in the outer area of the housing counteracts the deflection.
- the product leakage current is discharged under the bearing inner ring, either straight or obliquely to the axis through grooves in the gear shaft, grooves in the bearing inner ring or through bores in the gear shaft so that the roller bearings do not come into contact with the medium to be conveyed.
- the side seals can have less play in order to minimize the leakage current.
- the service life of the roller bearings is many times longer than that of plain bearings. Since all pump parts can be made from metallic materials, you can also work with high media temperatures and the rolling bearing results in lower energy consumption compared to plain bearings.
- Figure 1 shows a gear pump in section through the middle of the housing
- Figure 2 shows a gear shaft with the holes for the leakage current removal
- Figure 3 shows a sealing washer for the leakage current in plan view - on the bearing side
- Figure 1 shows a schematic section through the middle of the pump housing 12 with the internal gears 1, 8, wherein the sealing washers 3 are arranged directly on the end flanks of the gears 1, 8 and are secured against rotation with a pin 11.
- the sealing disc 3 closes the side rolling bearing opening and presses the leakage current through the slots 2 under the bearings into the open.
- the Aufhahmbuchsen 5 for the roller bearing 4 close the opposite roller bearing opening, so that the product leakage current can not destroy the roller bearing 4.
- the support bearings 9 arranged in the housing cover plates 6 largely prevent the gear shafts 1, 8 from bending.
- FIG. 2 shows a gear shaft 1 with the bores 10 for the removal of the product leakage current through the center of the gear shaft 1.
- Figure 3 shows a plan view of the sealing washer 3 with the arrangement of the return thread 13 to the inner bearing ring 4a and the arrangement of the locking pin 11 against rotation. 4 list of reference symbols
