Abstract
The utility model relates to a supporting structure of a heading machine drive spindle. The supporting structure comprises a cutter head (1), a main seal (2), a front centering bearing (3), a soil cabin panel (4), a power box (5), a rear end cover (6), a rear centering bearing (7), a large gear (8), a thrust bearing (9) and a drive spindle (10). The supporting structure is characterized in that the front end of the drive spindle (10) is supported by an inner ring of the front centering bearing (3), the rear end is supported by an inner ring of the rear centering bearing (7), and the middle is supported by an inner ring of the thrust bearing (9); the outer rings of the three bearings are all fixed on the power box (5) which is fixedly connected with the shell panel (4); the large gear (8) fixed on the drive spindle (10) is positioned between the thrust bearing (9) and the rear centering bearing (7); and the main seal (2) is arranged in front of the front centering bearing (3). The supporting structure has the advantages of convenience in manufacturing, length reduction of the drive spindle, great reduction of the manufacturing cost, and the like.
Description
Technical field
The utility model relates to the development machine that a kind of jacking construction uses and uses the main shaft supporting form, specifically uses spindle support structure for development machine provides a kind of practical and effective development machine.
Background technique
Part city, the whole nation has exposed water supply, the serious backwardness of drainage pipeline networks and the incompatible phenomenon of high speed development in each city of since China's reform and opening because of heavy rain generation waterlogging.The non-excavating construction rock tunnel(ling) machine; Engineering constructions such as the drinking water pipeline net that can be used for laying in the municipal engineering, sewage and storm-water drainage pipeline, various oily conveyance conduit, electric power, communication engineering pipeline; And spindle support structure is directly confirmed the success or failure of tunneling construction in its stability, reliability, working life as the critical component of development machine.At present; The main shaft supporting form of development machine adopts thrust-bearing rear-mounted more; Be characterized in that the thrust-bearing inner ring is installed on the end of main shaft, the outer ring has been installed on the gear box cover, and gear box cover is connected with deceleration box through high-strength bolt; The axial force that main shaft bore has so mainly acted on gear box cover and the attachment bolt, and this is the main cause that gear box cover distortion and speed reducer leakage of oil often appear in present development machine.Therefore, press for provide a kind of more rationally, longer main shaft of boring machine support arrangement structure of life-span.
Summary of the invention
The technological scheme of the utility model can overcome above-mentioned deficiency and defective, and a kind of reasonable more, longer main shaft of boring machine support arrangement structure of life-span is provided.The technological scheme of the utility model is: a kind of supporting structure of development machine drive main spindle; Comprise cutterhead (1), primary seal (2), preceding alignment bearing (3), native storehouse panel (4), power box (5), rear end cover (6), back alignment bearing (7), gearwheel (8), thrust-bearing (9), drive main spindle (10); It is characterized in that of the inner ring supporting of the front end of drive main spindle (10) by preceding alignment bearing (3); The rear end is by the inner ring supporting of back alignment bearing (7); Middle inner ring supporting by thrust-bearing (9); The outer ring of these three bearings all is fixed on the power box (5) that is fixedly connected with case panel (4), and the gearwheel (8) that is fixed on the drive main spindle (10) is positioned between thrust-bearing (9) and the back alignment bearing (7), is provided with primary seal (2) in the front of preceding alignment bearing (3).
Description of drawings
Accompanying drawing 1 is the general structure schematic representation of the utility model.
Embodiment
The utility model is described further with embodiment below in conjunction with accompanying drawing 1.
Accompanying drawing 1 is a kind of embodiment of the utility model; Its technological scheme is: a kind of supporting structure of development machine drive main spindle; Comprise cutterhead 1, primary seal 2, preceding alignment bearing 3, native storehouse panel 4, power box 5, rear end cover 6, back alignment bearing 7, gearwheel 8, thrust-bearing 9, drive main spindle 10; The front end of drive main spindle 10 is by the inner ring supporting of preceding alignment bearing 3; The rear end is by the inner ring supporting of back alignment bearing 7, and middle inner ring by thrust-bearing 9 supports, and the outer ring of these three bearings all is fixed on the power box 5 that is fixedly connected with case panel 4; Be fixed on the drive main spindle 10 gearwheel 8 thrust-bearing 9 and the back alignment bearing 7 between, be provided with primary seal 2 in the front of preceding alignment bearing 3.
The axial force power transmission process of this structure is: be passed to drive main spindle 10 from cutterhead 1, be passed to thrust-bearing 9 again, be passed to power box 5 again, be passed to native storehouse panel 4 again, transmittance process obtains simplifying; Promptly optimized the force intensity that receives of rear end cover 6, made the designs simplification of rear end cover 6, reduced approximately about 60% with the material amount, shortened the axial length of rear end cover widely, 40% length of also corresponding shortening drive main spindle 10; Simultaneously, also optimized the force-bearing situation of power box 5,, installed from rear side and to change the front into and install, the requirement of construction bolt has been reduced greatly because power box 5 is installed on the position of native storehouse panel 4.Overall structure is more become rationally, and manufacture cost reduces greatly.
Claims (1)
1. the supporting structure of a development machine drive main spindle; Comprise cutterhead (1), primary seal (2), preceding alignment bearing (3), native storehouse panel (4), power box (5), rear end cover (6), back alignment bearing (7), gearwheel (8), thrust-bearing (9), drive main spindle (10); It is characterized in that of the inner ring supporting of the front end of drive main spindle (10) by preceding alignment bearing (3); The rear end is by the inner ring supporting of back alignment bearing (7); Middle inner ring supporting by thrust-bearing (9); The outer ring of these three bearings all is fixed on the power box (5) that is fixedly connected with case panel (4), and the gearwheel (8) that is fixed on the drive main spindle (10) is positioned between thrust-bearing (9) and the back alignment bearing (7), is provided with primary seal (2) in the front of preceding alignment bearing (3).
