Description

(54) Device for assembling and disassembling of thimble rings on shafts

The object of the invention is a device for mounting and dismounting of large and large numbering rings on shafts.

Up to now, and for the assembly and disassembly of larger ring sizes, the handheld uses a proportionally large force required to open or push the ring before assembly.

The disadvantage of the hitherto used cleats for the assembly and disassembly of large poetic rings is that they are very capricious, thus making them difficult to handle and difficult to handle. They also have the advantage of a simple tool in that some are provided with additional mechanisms to hold the initial ring in the upright position, without the need for a constant pressing of the handles.

The above-mentioned disadvantages are eliminated by the device for mounting and dismounting of the thrust rings on the shafts according to the invention, which is based on the fact that a sloping guide surface is formed on the right-hand legs and on the inside. In the noane teleae is stored the control acrut and rotatably mounted opening member. The spreading member is provided with actuating projections corresponding to and inclined guide surfaces. The other end of the control screw is provided with a key.

adap-fm for mounting and dismounting of the ring rings and even simple and easy assembly and disassembly, the device has relatively small dimensions. Another of his advantages is me

its versatility, because it allows the assembly and disassembly of the retaining rings on the shaft ’and its simple sound even into the hole.

A device for mounting and disassembling the retaining rings on the shaft is shown by way of example in the attached drawing.

The device for the assembly and disassembly of the retaining rings on the shaft X consists of a pivot of the boom arms J. pivoted by pins 2 on the noon body 2 · Inner sides of the working arms 1 are provided with inclined guide surfaces 8. χ. The rotating element 2 is mounted rotatable at the end of the roll 8 and sealed with a anti-falling ring 6. The other end of the roll 8 is provided with a key A0.

The function of the universal device for the assembly and disassembly of the initial rings on the shafts ´ is the same. The device for the assembly and disassembly of the initial rings on the shaft X and pushes the ends of the working arms 1 into the holes of the initial ring to be inserted into the groove on the shaft *. Turning the key 10 e turns the acre to weave from the nose body aa 2 and actuate the opening member 2, the opening member 2 pushes the inclined guide surfaces 8 to the inclined guide surfaces 8 and unwinds from the long working arms 1, thereby extending the opening ring for assembly. The initial ring aa thus stretched onto the shaft above the groove in which it is to be fitted. By turning the key 10 in the opposite direction, the acutrix 4, together with the opening member 2, releases the working arms 1, thereby sliding the a-ring into the groove on the shaft. When removing the initial ring from the shaft, the function of the device is opposite to that of the assembly.
