Abstract
The utility model relates to a colliery is lose -lose odd transmission for prebreaker in pit. Its characteristics are: include round bevel gear axle (1) and the dual output bevel gear axle (4) connected through bevel gear meshing and transmission, mutually perpendicular between this yuan of bevel gear axle (1) and the dual output bevel gear axle (4). The utility model discloses a lose -lose odd transmission has fully considered the operating mode environment in internal colliery, and its transmission structure is the bevel gear transmission, and the moment of torsion is big, small, light in weight, has fully considered the operating mode environment in internal colliery, and with reduction gear dual output transmission structure and broken axle integrated design in advance, mechanism structure is compact, high transmission efficiency, adapts to the colliery narrow and small operating mode environment in space in the pit first.
Description
Technical field
This utility model relates to a kind of underground coal mine prebreaker lose-lose and lifts one's head actuating device.
Background technology
The ature of coal in domestic colliery is different, and wherein the ature of coal of Part Coal Mine is harder, from drag conveyor
When being unloaded on stage loader, coal cinder is relatively big, is unfavorable for that stage loader transports, simultaneously because coal cinder
Excessive, cause the disintegrating machine of the most conventional configuration directly to crush relatively difficult, resistance coal phenomenon even occurs,
Have a strong impact on the coal mining efficiency in colliery.
It is difficult to broken gathering coal and the problem of resistance coal for existing disintegrating apparatus, fully studies coal mine user
Coal winning technology, analyze coal mine user operating mode, determine that precrushing equipment can solve current elevating conveyor
The problem of fortune coal.But there is no precrushing equipment both at home and abroad at present, be coal mining enterprise's high speed development in recent years
During the demand equipment that just occurs, and the core component of this one-level disintegrating apparatus to be exactly lose-lose lift one's head subtracts
Speed mechanism.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, transmission efficiency height, adapts to underground coal mine
Actuating device is lifted one's head in the underground coal mine prebreaker lose-lose of the work condition environment of narrow space.
Actuating device is lifted one's head in a kind of underground coal mine prebreaker lose-lose, and it is particular in that: include
The bevel pinion shaft engaged by bevel gear and be in transmission connection and dual output bevel gear shaft, this conical gear
It is mutually perpendicular between axle and dual output bevel gear shaft.
The most also include that casing, described bevel pinion shaft and dual output bevel gear shaft are pacified by bearing respectively
It is contained in this casing.
Outside wherein casing is stretched out in one end of bevel pinion shaft thus as power shaft, and dual output bevel gear
The two ends of axle are stretched out outside casing thus as two output shafts respectively.
Sealing member is wherein installed between power shaft and casing, and at least in two output shafts
Between individual and casing, sealing member is installed.
Wherein sealing member uses oil sealing.
Lose-lose of the present utility model is lifted one's head actuating device and has been taken into full account the work condition environment in domestic colliery, its
Drive mechanism is Bevel Gear Transmission, and moment of torsion is big, volume is little, lightweight, has taken into full account domestic colliery
Work condition environment, first by decelerator dual output drive mechanism and precrushing axle integrated design, mechanism
Compact conformation, transmission efficiency are high, adapt to the work condition environment of underground coal mine narrow space.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of underground coal mine prebreaker lose-lose lifts one's head biography
Dynamic device, including the bevel pinion shaft 1 engaged by bevel gear and be in transmission connection and dual output bevel gear
Axle 4, is mutually perpendicular between this bevel pinion shaft 1 and dual output bevel gear shaft 4.Also include casing 3,
Described bevel pinion shaft 1 and dual output bevel gear shaft 4 are arranged in this casing 3 by bearing 2 respectively.
Outside specifically casing 3 is stretched out in one end of bevel pinion shaft 1 thus as power shaft, and dual output cone tooth
The two ends of wheel shaft 4 are stretched out outside casing 3 thus as two output shafts respectively.At power shaft and casing 3
Between sealing member is installed, and be provided with close between at least one and the casing 3 in two output shafts
Sealing, this sealing member uses oil sealing 6.
Using method of the present utility model and operation principle be:
Its middle (center) bearing 2 refills on casing 3 after being contained on bevel pinion shaft 1, bearing 2 and bearing cap
5 and dual output bevel gear shaft 4 be assembled in one after integral installation enter casing 3.During work, circular cone tooth
Wheel shaft 1 input torque, the torque after the output of dual output bevel gear shaft 4 two ends is amplified drives broken shaft work
Make.
Two of which output shaft rotating speed is identical, and broken shaft and broken cutter tooth can be joined in two ends, power shaft with
Output shaft arrangement form in 90 °, one bevel gear of each self-retaining on two axles thus engage and transmit turn
Square, lose-lose lifts one's head into a word symmetrical structure, and actuating device of this lose-lose being lifted one's head during use is arranged on broken
Machine top, input connects driving motor, so that lose-lose is lifted one's head achieves integrated setting with broken shaft
Meter.
