Abstract
The utility model belongs to the improvement of a tunneller mechanism, which particularly relates to a cantilever device of a tunneller. The utility model is composed of a cutting head (1), a speed reducer casing (2) and a motor (3), wherein the motor (3) is transversely fixed in the speed reducer casing (2), a small column straight gear (7) is fixed on a motor shaft (4), a small column straight gear (6) and a large column straight gear (11) are fixed on a first shaft (5), a second shaft (8) is arranged between the first shaft (5) and the motor shaft (4), and a large column straight gear (9) engaged with the gear (7) of the motor shaft and a small column straight gear (10) engaged with the large column straight gear (11) of the first shaft are fixed on the second shaft (8). Because the motor is changed to a transverse arrangement, the shaft line of the cutting head is parallel to the shaft line of the motor, and a pair of cone gears is omitted, so the utility model has the advantages of low production cost, high bearing capacity, long service life, failure reduction and high productivity.
Description
Technical field
The utility model belongs to the improvement of development machine mechanism, particularly a kind of development machine cantilever arrangement.
Technical background
At present, the cutterhead axis of development machine is vertical with the axis of cut motor, so must adopt a pair of Bevel Gear Drive in the cut reducer, and partial-size tunneling machine belongs to heavy duty, high-power, the machinery equipment of mobile working under geological conditions occasion complicated and changeable, its load fluctuation, the machine shock and vibration are all very big, also often be in overload, use Bevel Gear Drive not only requirement on machining accuracy and cost of production height, and cantilever operating mechanism supporting capacity is low, the adjusting play difficulty, so serious wear, fault is many, reliability is low, it is fast to lose efficacy, and directly influences economic benefit and productivity ratio that development machine uses.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of development machine cantilever arrangement that improves machine supporting capacity and application life is provided.
The technical scheme that the utility model technical solution problem adopts is: the development machine cantilever arrangement is made up of cutterhead, reducer shell motor, be characterized in motor of crosswise fixed in reducer shell, on motor shaft, fixedly adorn a small column spur gear, on No. 1 axle, fixedly adorn a small column spur gear and a big column spur gear, between No. 1 axle and motor shaft, axle is housed No. 2, on No. 2 axles, fixedly adorn one with the big column spur gear of generator shaft gear engagement and the small column spur gear of No. 1 axle big column spur gear engagement.
The beneficial effects of the utility model are: because motor changes lateral arrangement into, make the axis of cutterhead parallel with the axis of motor, save a pair of conical gear, reduced cost of production, improve the supporting capacity and the application life of machine, reduced fault, improved productivity ratio.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows development machine cantilever arrangement schematic diagram.
Among the figure, the 1-cutterhead; The 2-reducer shell; The 3-motor; The 4-motor shaft; The 5-1 axle; 6-1 axle pinion; The 7-generator shaft gear; The 8-2 axle; 9-2 axle gear wheel; 10-2 axle pinion; 11-1 axle gear wheel
The specific embodiment
With reference to accompanying drawing 1, the development machine cantilever arrangement, it is made up of cutterhead 1, reducer shell 2 and motor 3.Motor 3 is arranged to the lateral attitude, motor 3 is parallel with the axis of cutterhead 1, on motor shaft 4, fixedly adorn a small column spur gear 7, on No. 1 axle 5, fixedly adorn a small column spur gear 6 and a big column spur gear 11, in reducer shell 2, adorn No. 2 axles 8 between motor shaft 4 and No. 1 axle, on No. 2 axles 8, fixedly be equipped with the big column spur gear 9 of generator shaft gear 7 engagement and with the small column spur gear 10 of No. 1 axle gear wheel 11 engagements.Adopt this cantilever arrangement stable drive, improve supporting capacity and application life, applicable to the occasion of various complexity.
Claims (1)
1, a kind of development machine cantilever arrangement, be by cutterhead (1), reducer shell (2), motor (3) is formed, it is characterized in that a motor of crosswise fixed (3) in reducer shell (2), upward fixedly adorn a small column spur gear (7) at motor shaft (4), upward fixedly adorn a small column spur gear (6) and a big column spur gear (11) at No. 1 axle (5), between No. 1 axle (5) and motor shaft (4), No. 2 axles (8) are housed, go up at No. 2 axles (8) and fixedly adorn a big column spur gear (9) that meshes with generator shaft gear (7) and the small column spur gear (10) that meshes with No. 1 axle big column spur gear (11).
