Embodiment Construction

[0015] Such as figure 1 As shown, the present invention includes: a first bearing group 1, a bearing support 2, a first tooth seal 3, a labyrinth seal 4, an eccentric shaft 5, a second tooth seal 6, a second bearing group 7, a bearing seat 8, Gear 9, third bearing 10, reducer 11, pinion shaft 12, hydraulic motor 13, round nut 14 and stop washer 15. The soil-sand sealing method is as follows: between the bearing support 2 and the eccentric shaft 5, a double seal of a labyrinth seal 4 and a first toothed seal 3 is provided, and between the bearing seat 8 and the eccentric shaft 5, a labyrinth seal 4 and a second seal are provided. The double seal of the two-tooth seal 5 is connected in the following way: the hydraulic motor 13 of the driving device and the base of the reducer 11 are connected with one end of the bearing seat 8 with bolts, and the output pinion shaft 12 of the reducer 11 is externally meshed with the gear 9. The gear 9 is set in the eccentric shaft 5 and connect...

Abstract

The invention is a kind of cutter plate driving device for eccentric multi spindle development machine, which belongs to building mechanical field. The sealing way of sand in the invention is: there sets a double sealing of maze sealing and the first teeth sealing between the bearing bracket base and the eccentric spindle, there sets a double sealing of maze sealing and the second teeth sealing between the bearing base and the eccentric spindle. The driving device hydraulic motor and the decelerator base are connected with one end of the bearing base through bolt. The decelerator output small gear spindle engages with the gear, the gear is covered in the eccentric spindle and connected with flat key, the second bearing and the third bearing in the bearing base are set on the neck part of the eccentric spindle, the first bearing in the bearing base is supported on another neck part of the eccentric spindle, the two ends of the eccentric spindle are fixed through a round bolt and stopping cushion to limit the axial movement of eccentric spindle. The invention reduces the project cost greatly and shortens the constructing period.

Description

technical field [0001] The invention relates to a driving device, in particular to a cutterhead driving device of an eccentric multi-axis roadheader, belonging to the field of construction machinery. Background technique [0002] Most of the underground tunnels adopt the single-axis large cutter head type shield, and the turning center of the cutting cutter head is consistent with the center of the roadheader. From the quarterly magazine "Underground Engineering and Tunneling" with the serial number CN31-1591 (No. 3, 1991) published on page 7 entitled: Introduction to the φ5.64M Earth Pressure Balance Shield Tunneling Machine and the main assemblies and systems of the shield It is found in the structure: the description of the driving device is as follows: cutterhead: adopts the middle support type. A total of 12 sets of hydraulic drive devices are installed. The drive device uses GFA105K travel reducer, and the two-stage reducer adopts external gear type. The bull gear is...
