Изобретение относитс к области бурени нефт ных и газовых скважин, в частности к конструкци м опор буровых долот.The invention relates to the field of drilling oil and gas wells, in particular to the design of drill bit supports.
Известны опоры шарошечных долот, состо щие из цапфы с подшипниками качени и сколь кени п узла герметизации, включаюш .его опорную шайбу и манжету, выполпенпую из эластичного материала.Roller-bit supports are known, consisting of a pin with rolling bearings and a slide of the sealing assembly, including its bearing washer and cuff made of elastic material.
Предлагаема опора шарошечного долота позвол ет повысить стойкость опоры и долота в целом.The proposed support of the roller bit makes it possible to increase the stability of the support and the bit as a whole.
С этой целью мапжету изготавливают из ирессованной спиральной проволоки, пропитанной наполнителем, например синтетическим каучуком.For this purpose, the mappet is made of pressed spiral wire impregnated with a filler, for example, synthetic rubber.
На фиг. 1 изображено долото с предлагаемой опорой; па фиг. 2 - узел герметизации опоры.FIG. 1 shows a chisel with the proposed support; pas figs. 2 - site sealing support.
Корпус 1 долота с системой принудительной смазки имеет лапы 2 с цапфами 3. Цапфа сThe case of 1 bit with a system of forced lubrication has paws 2 with trunnions 3. A trunnion with
помощью подшипников скольжени 4 и качени 5 св зана с шарошкой 6. Между торцовыми поверхност ми шарошки и лапы наход тс манжета 7 и опорна шайба 8.using sliding bearings 4 and roller 5 is connected with the roller cutter 6. Between the end surfaces of the roller cutter and the paws are a cuff 7 and a support washer 8.
Манжета изготавливаетс из прессованной спиральной проволоки, котора пропитываетс наполнителем, имеющим свойства резины, нанример синтетическим каучуком.The cuff is made of extruded spiral wire, which is impregnated with a filler having rubber properties, such as synthetic rubber.
