Adjustable journal bearing.

The device shown on adjustable journal bearings is intended to enable the location of the to change the current wave with ease and speed and at the same time to examine the concentric position of this shaft by means of a special device.

The eccentric b is seated in the bore α of the bearing block, and an eccentric c is fitted into this, in whose bore the bearing sleeve d provided with a flange is arranged. The shaft e rests in the latter. Each of the two eccentrics is provided with an ear b ¹ c ¹ . A screw-threaded bolt f and f ^{l is} rotatably fastened to each of these ears, the lower end of which is inserted through an eye g which is rotatably fastened to the bearing seat and is held on the same by means of nuts h. By turning these nuts, the mutual position of the eccentrics b and c can be changed, the bearing sleeve d can be raised or lowered and the position of the shaft e can be changed as required.

The sleeve d is prevented from rotating with the shaft by the pin i, which is screwed into the bearing block. Unsolicited turning of the nuts h is prevented by the fact that these nuts, the eyes g and the ends of the bolts ff ¹ are enclosed by a housing k , the opening of which can only be accomplished after the padlock j has been removed.

The device for measuring or examining the position of the shaft in the bearing block is shown in FIGS. On the bearing block there is a flange a ¹ concentrically with the hole for the eccentric and with the shaft in its initial position. In order to be able to examine the position of the shaft with accuracy, a sliding sleeve m is used which fits onto the shaft e and is provided with a flange m ¹ . This Flantsch can either form a complete circle or a part of a circle corresponding to the Flantsch a ^l of the bearing chair.

When the shaft e is in such a position that the flange m ¹ fits exactly on the flange a ¹ , the shaft again assumes its correct, initial position which is concentric with the bearing.

So that one is not hindered during the examination by pulleys or other parts sitting on the shaft e , and so that these disks or other parts do not have to be removed, the sleeve is open, Fig. 7, so that it can be pushed onto the shaft from the side.

In order to lubricate the shaft, the eccentrics are provided with slots, which correspond to holes in the bearing bracket and in the bearing sleeve d , so that a channel 0 is created on the upper side of the shaft e , while a channel o ^{l is created} in the same way on the lower side for discharging the lubricant after the container p, Fig. 3 and 6, is formed. The latter can be emptied from time to time through the cock p ^l.

The slots in the eccentrics must be long enough so that they can be adjusted

without the channels ο ο ^{1 being} closed.

Claims (1)

Patent Claims: i. An adjustable journal bearing, consisting of a sleeve d carrying the shaft e , which is arranged in an eccentric c enclosed by the eccentric b , and both eccentrics can be rotated independently of the sleeve d , so that the latter is raised or lowered and the one mounted therein Wave e can be easily and quickly determined in a certain position. The on the wave e one in claim i. described adjustable journal bearing mounted sliding sleeve m in connection with the flange a ^{1 of} the bearing block, whereby the concentric setting of the shaft with the latter can be checked. For this purpose ι sheet of drawings.
