Description

Lubricating device for coupling spindles, for example for roll stands With the coupling spindles in the roll stands z. B. is it a well-known phenomenon that the coupling sleeves are subject to severe wear s, inids. To the wear and tear to reduce the friction points from time to time, z. B. with With the help of grease presses, lubricants were supplied, but this measure did not work proved to be sufficient. As a result of the frictional wear, it can become so significant Clearances between: the flanks of the coupling pins of the Wglizien or comb rollers and .from that of the power transmission parts in the spindles that the Tapping the Walizigutessehr strong blows arise .. Such blows have dlan resulting in the upward bending of the gaibe.l, shaped spindle heads, thus a further increase the force of the blows, which can lead to breakage.

There are known devices in which the power transmission parts from the outside the spinideln and heads are sprayed with oil or emulsion. By centrifugal force However, if the lubricant is never driven outside the surrounding parts, so that the actual wear parts are not lubricated at all or only poorly lubricated will. This drawback is remedied by the invention.

The invention consists in that @ that in the, longitudinal direction of the spindles Channels for the supply of lubricants or coolants to serve on the spindle heads arranged lying power transmission points and the spindle heads under formation from Lubricant collecting tanks from cylindri-scheii support attachments, which are located on the brackets of the coupling pin., are enclosed.

The heads of the inclined spindles lead similarly when they rotate a pumping movement like a wobble piston. This will keep the lubricant in the the chamber surrounding the spindle heads is moved over and over again with the power transmission part brought into contact.

In the drawing, an embodiment of the invention is in use run a Duowa'.l (e.g. frame shown, in Fig: g. i in longitudinal section, in Fig. 2 in Cross section along line A-B in Fig. R. The diaphragm articulated spindles a are in the middle on a bearing bracket b with swivel brackets c and non-removable plain bearing blocks d stored. For the latter, the spindle parts are: n the Support surfaces for the consoles in the longitudinal direction beefy.

On both sides of the bearing rings is d pressure-tight manner to each spindle a respective Schmierrinig e via an annular groove f, fitted unverschieibbar urdrehbar and serving Längsrichtunig. From the f, a radial and a central bore g to the adjacent spindle head 1t, from the outer end of which radially arranged narrow channels i open into a recess in the spindle head; which the contact surfaces of the joint stones k finite. Coupling pin l on the one hand and the spiral head joint socket m on the other.

The spindle heads are each closely connected to the pin carrier L by one and at the same time serving as a spindle carrier cylindrical housing st under formation a lubricant chamber z well enclosed. The housing yt is mach outside by a ring disc o made of leather odi. Like. Sealing completed.

A common pressure pump p lubricating fluid (oil, emulsion or the like) is supplied to the lubricants via a pipe system q which is made movable (e.g. as a hose) to enable the height adjustment of the rollers. The chambers are filled with lubricating fluid, which, by virtue of the working pressure, forms a film of lubricant on the working surfaces of the gels, which considerably reduces the pressure between these working surfaces or, under certain circumstances, completely eliminates it, i.e. considerably reduces wear and tear. The side of the chambers z closed by the annular disk o: g: is practically pressureless due to the throttle losses between the spindle head and its support housing. Insofar as lubricant escapes from it, it is thrown by blades r on the spindle head eire spray hood s, in which it flows into the collecting tank t, which is covered with a sieve 24. This container serves as a suction container for the pump p in the lubricant circulation. The return takes place from the pressureless side of the chambers, z through drainage lines v, which can be provided with control valves w. To prevent this rotation of the lubricating rings e, the same can be provided, for example, with lugs x, which are located between stop cams y on the bearing bodies. d grab.
