Abstract

The invention relates to preparatory work mechanization and is intended for use in roadheaders, drilling and boring machines and rifled combines. The goal is to increase productivity. The planetary executive body of the sinking combine includes a central shaft 1, a planetary gear with a sun wheel (K) 2, satellites (C) 3, a crown 4, carrier 5, mounted in housing 6 on bearings 7. 8 On the central shaft 1, solar K 2 and K 9 cylindrical gears are mounted. Another K 10 of the latter is mounted on shaft 11 with the possibility of interaction with K 9. Solar K 12 is fixed on the main shaft 11 of the planetary gear system With a crown 13, C 14 and drove 15 installed in the carrier 5 with maybe Spin on the main shaft 11 is fixed with a C 17 differential gear, the conical K 18 of which is mounted on the shafts 19 with the possibility of rotation in the carrier 15 and on which the cutting drums 20 with cutting disks 21 are rigidly fixed. The power flow from the engine through the central shaft 1 is branched on a solar K 2 into two streams A and B. As a result of this, three movements are summed up on the tool: 1 - rotation of tools around shafts 19 with a relative speed of W1, 2 - rotation of a tool around the main shaft 11s with a portable speed of Sh 2 per - 3 - rotation of the tool around the central shaft 1 together with the entire cutting mechanism with a portable speed ftfcnep The tool of the cutting disks 21, having made a relative and two portable movements, cuts off the entire bottom surface. 2 Il.

Description

The invention relates to the mechanization of preparatory work in the coal industry and is intended for use as executive bodies in tunneling machines, continuous drilling machines and rifled combines.

The aim of the invention is to increase productivity.

FIG. 1 shows a diagram of the planetary executive body of the tunneling machine; Fig, 2 - the same, front view.

The planetary executive body of the tunnel miner consists of a central shaft 1, an additional planetary gear with a sun wheel 2, satellites 3, a crown 4, an aodil 5, which is mounted in E housing 6 on bearings 7, 8. The sun shaft 2 and wheel 9 are fixed on the central shaft cylindrical gear, the other wheel 10 of which is installed on the main hall 11 with the ability to interact with the wheel 9. On the main shaft 11 is rigidly fixed the solar wheel 12 of the planetary gear with the crown 13, satellites 14 and carrier 15, installed in the carrier 5 rotatably on bearings 16. In addition, a differential transmission satellite 17 is fixed on the main shaft G /, the conical wheels 18 of which are mounted on shafts 19 are rotatable in the carrier 15 and on which the cutting drums 20 with cutting discs are rigidly fixed 21.

Fig. 2 shows the direction of rotation of the cutting discs 21 relative to off-gate 19 at a speed jMgn. The portable movement of the cutting discs 21 relative to the main shaft 11 is its speed a / znep; the second portable movement of the cutting disks 21 relative to the central shaft 1 at a speed (knotter.

The planetary executive body of the tunneling machine works as follows.

The powerful flow ™ from engine D through the central shaft 1 unwinds on the sun wheel 2 into two streams A and B. The stream A through satellite 3 and crown 4 goes to the rotation of the carrier 5 relative to the central shaft 1 and the planetary gear 12, 13, 14, as well as their drums 20 at a speed of GuS. The second power flow B is transmitted to the wheels 9, 10 and the main shaft 11. Further, the power flow B is split into two

current Bi and §2. The flow Bi, the passage through the main shaft 11, the satellite 17, the bevel gears, the 18 differentials and the shafts 19, goes to the rotation of the cutting discs 21 at a speed of # 1 lm. Power flow B2. the passage through the planetary gear 12, 13, 14 rotates the carrier 15 relative to the main shaft 11, forcing the cutting discs 21 to rotate at a portable angular velocity ftЈnep relative to the main shaft 11. In addition, on the driver 15, the power flow A is added to the power flow B2 .

As a result, the tool combines three movements: rotating the tool around the shafts 19 with a relative speed., Rotating the tool around the main shaft 11 at a portable speed. U2 per: rotating the tool around the central shaft along with the entire cutting mechanism with a moving speed.

Thus, the tool of the cutting discs 21, having made a relative and two portable movements, affects the entire surface of the pile with a flaking edge. Such an executive body does not have a logger to destroy the central part.
