Description
вижной 3 частей, св занных между собой подшипником 4, раму 5 подвески фрезы 1 и привод, передающий крут щий момент фрезы 1 через вал-шестерню 6. Внутреннее вращающеес кольцо 7 подшипника 4 соединено посредством крепежных элементов 8, с вертикальным листом 9 фрезы 1, жестко св занным с кольцевым ободом 10, на внутренней поверхности которого посредством выступа 11 установлено уплотнение 12, взаимодействующее с наружным кольцом 13 подшипника 4, в результате чего одно уплотнение исключено, а у второго уменьшен диаметр, по которому происходит его взаимодействие, так как уплотпение работает внутренней частью.3 parts, interconnected by bearing 4, frame 5 of suspension bracket 1 and drive, transmitting torque of cutter 1 via gear shaft 6. Internal rotating ring 7 of bearing 4 is connected by means of fastening elements 8, to vertical sheet 9 of cutter 1, rigidly connected to the annular rim 10, on the inner surface of which, by means of the protrusion 11, a seal 12 is installed, which interacts with the outer ring 13 of the bearing 4, as a result of which one seal is eliminated, and the second one has a reduced diameter the interaction, since the seal acts as an interior.
Работа рабочего органа осуществл етс следующим образом.The work of the working body is carried out as follows.
Крут щий момент от двигател через промежуточные передачи передаетс валушестерне 6 и, далее, через зубчатый венец внутреннего кольца 7 подшипника 4 подвил ной части 3 фрезы 1, котора вращаетс и взаимодействует уплотнением 12 с наружным кольцом 13 подшипника 4. При работе взаимодействие с уплотнением происходит по меньшему диаметру, что позвол ет по сравнению с сушествующим рабочим органом значительно уменьшить потери , а высвободившуюс мощность использовать на повышение производительности экскаватора в целом.The torque from the engine is transmitted through intermediate gears to the shaft gear 6 and, further, through the gear rim of the inner ring 7 of the bearing 4 of the base part 3 of the milling cutter 1, which rotates and interacts with the seal 12 with the outer ring 13 of the bearing 4. During operation, the interaction with the seal smaller diameter, which makes it possible to significantly reduce losses in comparison with the existing working body, and use the released power to increase the performance of the excavator as a whole.
