DE19511765A1 - Equipment to lubricate gear wheels using absorbent gear block - Google Patents

Abstract

The equipment has individual felt gear slicing (4), which have a gearing which matches that of a gear wheel (1) which is to be lubricated. They are aligned in a circumferential direction and are supported by discs (3), which are preferably at regular spacings, and are tensioned axially in order to form a gear block (2) which can absorb lubricant. The block has rotary bearings, and is mounted so that it engages with the gear wheel. The discs may have a gearing profile which is set back from that on the felt slicing. Both may be tensioned on a sleeve (8) which is mounted on an axle (15) which can be adjusted radially with respect to the gear wheel.

Description

The invention relates to a lubrication device for gears according to the Preamble of claim 1.

It is generally known to use machine parts in the operating state of a felt attached to them, soaked with a lubricant lubricate.

With gears, however, the effect that can be achieved in this way is single Lubricated tooth head and unlubricated tooth flanks for one trouble-free operation is not sufficient.

The invention has for its object a lubrication device according to the preamble of claim 1 to create that with relatively little Effort especially the lubrication of wide gears over a length maintenance-free period with the greatest possible avoidance of a functional Ensure overdosing and splashing of the lubricant continuous

The object is achieved by the characterizing features of claim 1 as well as the subclaims which form these.

The production of narrow felt gear blanks and their joining towards a width corresponding to the gear to be lubricated, sufficiently stiff gear block due to the interposed support washers can be implemented with little effort.

The composite felt body also has one for a longer war Sufficient storage capacity in connection with a positive fixation of the felt gear blanks by their vari axial pressure is still favored.  

The flexibility of the gear block in the area of the teeth is for everyone ge, intensive lubrication of the rolling surfaces of the teeth of the gear advantageous adherent, but also in this area thanks to the support washers Avoid permanent deformations that impair the lubrication process stiffness is guaranteed.

The gear block has due to the possibly variable bearing friction the driving gear one for the formation of the lubricating film adequate contact.

In conjunction with protection of a thin lubricating film The gear block becomes one that is cleaner for the environment, for others Lubrication processes can only be implemented with considerable additional effort Lubrication, in particular of individual, separately arranged gear wheels achieved.

The invention is explained in more detail below using an exemplary embodiment tert. In the accompanying drawing:

Fig. 1 shows a longitudinal section of a felt according to the invention of a plurality of gear blanks compounded gear block according to the cut AA of Figure 2.

FIG. 2 shows a cross-section of the gear block in accordance with the cut BB of Figure 1.

Fig. 2 shows a gear 1 to be lubricated gear block 2 which , with the interposition of somewhat set back support disks 3, is composed of individual felt gear blanks 4 ( FIG. 1), on the one hand with an axial stop 5 and on the other hand with a thread 6 for a clamping nut 7 equipped sleeve 8 via bore-side grooves 9 ( Fig. 2) with respect to keys 10 of the sleeve 8 are arranged fixed in the circumferential direction ( Fig. 1).

The sleeve 8 is on one at each end a radially to the gear 1 via a stud 11 pivotally attached to the frame 12 lever 13 ; 14 bearing axis 15 rotatably mounted on the next to the levers 13 ; 14, a gear 16 covering the gear block 2 , leaving its engagement area to the gear 1 , is fixed on all sides.

The additional arrangement of friction elements (not shown) with an adjustable contact force between the fixed axis 15 and the rotatable sleeve 8 allows the contact force of the gear block 2 and thus its wiping effect with respect to the gear 1 to be varied.
