PL104262B1 - DEVICE FOR CENTERING WALOW IN LOZYSKI - Google Patents

Description

The subject of the invention is a price device keeping shafts in bearings, • in particular rollers with bracing themselves in plain bearings. Authorities ~ not it is also useful for assembly, tran¬ sports and shaft-building.

For centering horizontal and vertical shafts, eg shafts rotating in sliding bearings it is assumed that it is in the inner walls housing, at the places where the shaft exits, the centering rings are prompted. Such a ring centering slats are usually two-part i must be done specifically for each quantity dice in diameter. These rings are put in the ditch and fastened with a few screws to the housing you. Their production is expensive and their application to assembly and disassembly is very time consuming.

It is impossible to use these rings turning of shafts without additional tools and feed carriers. There is also the danger of ears damaging the shafts by a device rotating the shafts zygomatic knitting.

The object of the invention is to eliminate the known ones defects and the creation of a centering device, mon¬ tazu, transport, setting and at the same time the device precautionary measures that may be used simple measures without major operations machining and regardless of the diameter of the shaft and direction of rotation. This task is completed in such a way that the bearing housing has each ring-shaped on its front sides, open towards the center of the shaft and coaxial a roll in which a chain of drums is placed bay, having its treadmill in this roll and thus lifting the shaft.

Then the ladder chain is on the on-shaft secured against axial misalignment.

Ladder chains may be on the shaft diameter folded, with appropriate lengths, to the forehead sides of the housing. They could be otherwise used one-sided or two-sided and with single with single or multiple ladder chains dim.

Hardened ladder chains are available in the trade of chains with roll diameters they are larger than connecting links. These chains are installed in the grooves, in the housing from the side the forehead and with clamps or similar ments secured against shifting axial. The shaft is centered and lifted through the rollers. During the assembly of the bearings it can show the necessary rotation of shafts in bearings, for example when shafts are operated on cut It was possible to introduce individual elements to be cut insert into the housing through the holes. Turning the shaft bearings with an installed chain ladder can then take place without a meeting of chanical and hydraulic devices and without damage to the shaft or housing and no effort required with little force for a given occasion the fall of manual force. 104 262 104 262 When transporting the bearing with the shaft, the shaft is also lifted by a ladder chain, so that both the housing and the shaft engage safe during transport against damage to me. 5 When using the device on board ships, individual shafts may be for sale the entire sequence of shafts placed in the given positioned in bearings effortlessly and efficiently in this case without a turning device. After 10 the shafts, and before their final sale creasing, ladder chains must be replaced tented to relieve the front side of the housing the bearings.

The advantages of the device according to the invention lie in 15 mainly on their simple and economic performance niu and the possibility of each time, repeated using them, with the same effect.

The subject matter of the invention is illustrated in example I refer to the embodiments in the drawing in which Fig. 1 20 shows a ladder chain placed on the ground between the shaft and the bearing housing, Fig. 2 shows partial cross section of the bearing housing.

The bearing housing 1 has a face on its side 2 a groove 3 in the form of a ring which has a crimp (7) or the like. it is worth to the center of the shaft and to its forehead. In coaxial roll-on 3 is placed lan-, ladder chain 4, which on shaft 5 and on its roll 3 on surface 6 has its raceways, i which shaft 5 leads and carries. Ladder chain 4 is secured against axial shift before using clamp 7.

The ladder chain 4 is an access chain in trade, whose rollers have a diameter on 8th greater than the links connecting 9 and 10.

Claims (2)

Patent claims 1. Device for centering shafts in bearings and for securing them against damage during assembly and transport, characterized in that the bearing housing (1) has an open to the center of the shaft and a coaxial groove (3) in which a ladder chain (4) is located, which has its own raceway on this shaft and in the roll-on and this shaft vibrates. 2.
