Abstract

The invention relates to mining equipment used in the coal and mining industries. The goal is to increase the compactness and simplify the design of the executive body of the combine. The executive body includes cutting disks 1 and 2 mounted on the boom 5 and gearboxes (P) 3 and 4 of relative and portable movement, made in the form of planetary gears (PP) 8 and 9 with carrier 11, sun wheels 12, crowns 13. Rotation from the drive motor 10 is transmitted to PP 8 P 3, then from carrier 11 through gear coupling 14, to shaft 15 and through wheels 16 to cutting disks 1 and 2. Simultaneously from driver 11, rotation is transmitted to sun gear 12 P 4 and through PP 9 to the crown 13, which is mounted in the movable housing 6 of the boom 5 and rotates the cutting Discs 1 and 2 relative to the shaft 15. 1 Il.

The invention relates to the construction of planetary working bodies of a mining combine used in the coal and mining industries.

The purpose of the invention is to increase the compactness and simplify the design of the executive body of a mining combine. The drawing shows the kinematic scheme of the executive body.

The executive body of the mining combine contains cutting discs 1 and 2, gearbox Q relative 3 and portable 4 motion, boom 5 with movable 6 and fixed 7 bodies, planetary gears 8 and 9, drive motor 10. Drove 11 gear 3 relative motion kinematically with the sun gear 12 of the gearbox 4 5 that, in order to increase the compactness and portable movement, and the crown 13 of the gearbox simplifies the design of the actuator, the gearboxes of the portable and relative rotation are made in the form of planetary gears, wheels, water wheels and rims, are connected in series and arranged coaxially along the longitudinal axis of the actuator, while the carrier of the relative rotation gearbox is kinematically connected with the sun gear of the portable rotation gearbox, and then through the wheels 16 to the cutting distributor of the relative rotation gearbox ki 2 and 1. At the same time rotation from in-installed on the movable part of the body.

Dila 11 is transmitted to the solar jaw 12 of the gearbox 4 of the portable movement and by means of the aerial gear 9 to the crown 13, which is mounted on the movable body 6 of the boom 5 and rotates thus the cutting disks 1 and 2 relative to the shaft 15.

Claims (1)

Invention Formula The executive body of the mining combine, comprising a housing consisting of fixed and movable parts, cutting bodies attached thereto, portable and relative rotational gears, planetary gears characterized in that. A portable movement 4 is mounted on the movable body 6 of the boom 5. The executive body of the mining combine works as follows. The rotation from the drive motor 10 is transmitted to the planetary gear 8 of the reducer 3 relative motion, from the carrier 11 through the gear coupling 14 to the shaft 15 and yes20 Dila 11 is transmitted to the solar jaw 12 of the gearbox 4 of the portable movement and by means of the aerial gear 9 to the rim 13, which is mounted on the movable body 6 of the boom 5 and thus rotates the cutting disks 1 and 2 relative to the shaft 15. Invention Formula that, in order to increase the compactness and simplify the design of the actuator, the portable and relative rotation gearboxes are made in the form of planetary gears, with sun wheels, water wheels and rims, are connected in series and arranged coaxially along the longitudinal axis of the actuator body, while driving the gear box of relative rotation kinematically associated with the sun gear of the portable rotation gearbox, and the crown of the relative rotation gearbox is mounted on the movable part of the housing. The executive body of the mining combine, comprising a housing consisting of fixed and movable parts, cutting bodies attached thereto, portable and relative rotational gears, planetary gears characterized in that.
