Description
Related application
The application is the co-pending U.S. Patent application No.12/475 that formerly submitted on May 29th, 2009, and 456 part continues.
Technical field
The utility model relates to a kind of machine, and this machine comprises gear-box compactness, high power density that is used for from driver to the driven member transmitting rotary power, and, more specifically, relate to the such gear-box that comprises improved cooling system.
Background technique
There is multiple different equipment, is used for from subsurface formations exploitation coal and other material.A kind of equipment that is widely used in the underground mining operation comprises the continuous miner device, and this mining device is applied in the situation of the extension of wishing productive formation or longwell.Described longwell depends on that earth formation can outreach 300-1200 foot.In such exploitation, the operation of standard is that the exploitation parallel roadways connects these tunnels to the stratum that will exploit and with one or more central core of circulation.This layout defines the longwell column that will exploit.During the exposure " face " of exploitation longwell column, the top of central core of circulation is supported with top support movably usually.
Traditional broadwall technology adopts a kind of mining device, and it is known to longwall shearer in industry.Longwall shearer generally has elongated movable frame, and this movable frame is supported on and is installed on the track on the ground, and this track is adjacent with production face and substantially parallel with production face.Rotation driven belt dental roller operationally is supported on the arm at each place, end of elongate frame, be used for when framework before production face back and forth by the time coal mining.Adopt material fall on the face conveyor, this face conveyor usually attaches to be installed on the ground track and with the longwell face and extends abreast.The face conveyor is discharged to material on other the conveying equipment and transports described material from this stratum.When production face retreated, conveyor and rail assembly advanced forward to make coal winning machine continue exploitation.
As shown in Figure 1, longwall shearer mining device 10 has elongated movable frame 12, and this framework is supported on the conveyor/orbital path 14 substantially parallel with longwell face 15 movably.The rotating drum 18 of horizontal expansion has a plurality of exploitation picks 19 that are attached to this rotating drum 18, and this rotating drum 18 is articulated on each end of described elongated movable frame 12 by corresponding rocking arm 16.The exploitation field that operates in of coal winning machine 10 is known, therefore will not discuss in detail here.Yet those of ordinary skills will appreciate that, coal winning machine 10 moves around at orbital path 14, so that the exploitation pick 19 on the rotating drum 18 can engage with production face 15, to remove from it material.When this face retreated, orbital path 14 and coal winning machine 10 advanced forward that towards described 15 recovery process is proceeded.
The gear-box that is applied to the rocking arm of longwall shearer needs very high specific power.This is because the output of the theory of mining device is proportional to its installed power, and that the operating range in mine need to encapsulate is as far as possible little.The heat that these powerful gear-boxes produce must be removed to improve long-term reliability continuously.
Longwall shearer rocker gear case is special-purpose in essence.Their need compact as far as possible simultaneously reliably transmitting rotary power to cutting roller of coal cutter.As the gear-box of many high power densities, from the loss of rolling element and the deviation energy Heat of Formation of oiling agent.In order to prevent that gear-box is overheated and damage oiling agent, Sealing and miscellaneous part, usually cool off the method for these unit in conjunction with some.
Further, the rocker gear case need to have specific shape, so that their long enoughs are to extend between input motor and output shaft.Because this feature, they have a plurality of individual gears usually, as known extension gear, (common 2 to 5) in a row are installed come spaced apart input shaft and output shaft.Quite major part when the heat in the generation gear-box when in the lubricant oil of these gears, stirring of each gear in these gears.In addition, the friction of their rolling unit supporting element further promotes the generation of heat.
Independent water-the cold heat exchanger that is installed in the fuel tank is used in traditional rocker gear case design, perhaps is installed in the interior heat exchanger of housing of gear-box.
These two kinds of methods all need on the gear-box size moderately large and increase manufacturing expense.In the both of these case, all there is risk that water that internal lubrication oil revealed in the heat exchanger pollutes or by because for the risk of water being sent into water and the dust from the environment that cause with the needed opening at housing of discharge unit and being entered pollution.
The model utility content
The utility model proposes and utilize the space of underusing in the gear-box: extend the gear installation shaft.These installation shaft be positioned at 2 to 5 extend gears each the center and be used for rigidly Support Gear.The diameter of these axles is enough large diameters, with suitable size of extending the required bearing of gear inside, and also enough is delivered to the power that then axle is delivered to housing to support reliably from gear by bearing greatly.
The gear installation shaft that the utility model relates in rocking arm increases boring.Then water transmits by these axles, removes the heat in very close source, and brings very little additional complexity.
Significance of the present utility model is that it is a kind ofly to remove heat and need not increase the effectively method cheaply of its size from gear-box for realizing.Usually, at enclosure interior or the outside heat exchanger that increases, they need whole encapsulation to increase.Because gear shaft is pre-existing in, can not increase its overall package size so increase cooling unit at the center.The center of these gear shafts is not utilized usually, thus for adapt to this feature in the gear-box not needs trade off.
This design utilizes in these axles each as independent heat exchanger.Each axle is holed to receive coolant flow.Removing of the heat in the very close source of this permission.The design's advantage is:
1. this cooling means does not need to increase the volume of gear-box.
2. it is very cheap giving these axle borings in the normal manufacture process of these axles.
3. because axle is that sealing material is made and water does not connect by the wall of gear box casing, so water does not flow into the chance in the lubricant oil.
4. because in the design of traditional rocking arm, axle is installed on the limit of tube seat, so do not need special the setting with the supply freezing mixture to axle.
5. be installed near the thermal source owing to them, so they are effective heat exchangers.
Therefore, the utility model provides the cooling system of the gear-box in a kind of rocking arm of longwall shearer, and this rocking arm is included in one or more gears in a row are installed in the elongated housing.Cooling system is included in the coolant injection system in each individual gears, and each coolant injection system is included in the one or more longitudinal openings in the gear shaft, and can comprise the coolant injection tube that is installed in the longitudinal opening.The diameter of coolant injection tube is less than the diameter of longitudinal opening.
