Description

A kind of locomotive decelerator of branch mailbox independent lubricating
Technical field
The utility model relates to decelerator technical field, and the travelling gears at different levels that are specifically related to a kind of separate-box type are equalThe locomotive decelerator of energy independent lubricating.
Background technology
In railway, metallurgy and mine industry, the driving power of motor vehicle running wheel generally derives from motor(hydraulic motor) and decelerator, power increases after square by the deceleration of decelerator, is directly passed to and is contained in decelerationTwo running wheels on device output shaft, thus drive motor vehicle straight-line travelling on rail. Normally used subtractingSpeed device has cylinder gear speed reducer, conic reducer and planetary reducer etc., due to the length of motor vehiclePhase, in the high severe working environment of dense dust, high humidity and corrosivity, so just requires the tooth of deceleratorWheel transmission has good lubricated and sealing state. Conventionally the energy-efficient lubricating system of decelerator is the profit of splashingSliding, utilize the rotation of gears at different levels to drive lubricating oil in reduction case, to produce flowing of splash, fromAnd reach the effect of oilgear and bearing. Conventionally the gear drives at different levels of decelerator all concentrate on independent oneIn individual fuel tank, require the fuel head setting of lubricating oil very high, guarantee good gears lubricated at different levels and axleHold, produce very large pressure will inevitably to like this seal of decelerator, greatly reduce its sealing property, giveThe working service of decelerator is made troubles.
Utility model content
The purpose of this utility model is in order to make up the deficiencies in the prior art, and a kind of branch mailbox independent lubricating is providedLocomotive decelerator, the high-speed heavy loading locomotive being made up of Bevel Gear Drive and column gear transmission slows downDevice, because its gearratio is large, bearing capacity, therefore the structure of decelerator and volume are relatively large, for ensureingDecelerator has good self-lubricating and sealing property, has designed an independently grease-box, by two-stage toothWheel the lubricated of transmission separated, and reduces the whole height of gear reducer lube face, thereby guarantee deceleratorLubricate and sealing property.
In order to reach the purpose of this utility model, technical scheme is as follows:
A locomotive decelerator for branch mailbox independent lubricating, is characterized in that, comprises by upper box, lower box groupThe casing becoming and output axletree, output axletree is through whole lower box, output axletree two outsideSide is connected with running wheel; Output axletree is positioned at casing one side and is connected with output Cylinder Gear by flat keyWheel; In described upper box, be provided with input bevel pinion shaft, conical gear, Cylinder Gear wheel shaft, described circular coneOne end of gear shaft is connected with input adpting flange, the other end and is connected with a joggle with conical gear, conical gear andCylinder Gear wheel shaft is by spline joint, and Cylinder Gear wheel shaft and roller gear are connected with a joggle, and arrange one in upper boxIndependently the 3rd casing, the main inner chamber of the 3rd cabinets cavity and upper box, lower box is kept apart, roller gearOne end that axle is connected with conical gear is placed in small box, and it is another that Cylinder Gear wheel shaft engages with output roller gearOne end is placed in the outer upper box of the 3rd casing.
Preferably, at the boundary of the 3rd casing and upper box, Cylinder Gear wheel shaft is provided with the oil for isolatingStrip of paper used for sealing, separates the Bevel Gear Drive of decelerator and column gear transmission independent lubricating.
Preferably, in the 3rd casing and lower box, lubricating oil is housed, in lower box, the liquid level of lubricating oil is lowIn the downside height of output axletree; The center of lubricating oil liquid level height and Cylinder Gear wheel shaft in the 3rd casingLine height is identical.
The beneficial effect the utlity model has:
The power of motor (hydraulic motor) subtracts by the decelerator of conical gear and column gear transmission compositionSpeed increases after square, is directly passed to and is contained in two running wheels on decelerator output axletree, thereby drive motor-drivenCar is straight-line travelling on rail. Decelerator is high-speed overload gear drive, and its structural volume is larger, is slowing downThe main box inside of device arranges a small-sized additional casing, and its Bevel Gear Drive and roller gear gear are passedMoving separating, carries out independent lubricating, reduces the height of gear reducer lube face, also lowers lubricating oil simultaneouslyPressure when work, decelerator seal being produced, makes it in severe working environment, have good profitSlide and sealing property.
Lubricated and the good seal performance, safe and reliable of the utility model decelerator, driving torque is large, structure is tightGather, manufacturing cost is relatively low, transmission efficiency is high. Can effectively ensure that decelerator is at the working environment severeIn there is good lubricated and sealing property, reach the demand of automobile safety and efficient operation.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is notOnly be confined to embodiment.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of locomotive decelerator of branch mailbox independent lubricating, comprisesThe casing being made up of upper box 1, lower box 2 and output axletree 10, output axletree 10 passesWhole lower box 2, two outsides of output axletree 10 are connected with running wheel (not illustrating), running wheelBe positioned at the both sides of lower box 2. In output axletree 10 casings, a side is connected with output Cylinder Gear by flat keyWheel 9, a part for roller gear 9 is positioned at lower box 2, and another part is positioned at upper box 1.
In upper box 1, be provided with input bevel pinion shaft 4, conical gear 6, Cylinder Gear wheel shaft 7, circular cone toothOne end of wheel shaft 4 is connected with input adpting flange 3, the other end and conical gear 6 and is connected with a joggle, and input connectsActing flange 3 is inputs of outer power, connects power input mechanism. Conical gear 6 is logical with Cylinder Gear wheel shaft 7Cross spline and be fastenedly connected, Cylinder Gear wheel shaft 7 is connected with a joggle with roller gear 9. Bevel pinion shaft 4 is by defeatedEntering conical gear axle bearing 5 is connected on upper box 1. Upper box 1 is interior arranges the 3rd casing 12 independently,The main inner chamber of the 3rd casing 12 inner chambers and upper box, lower box is kept apart, Cylinder Gear wheel shaft 7 and circular cone toothOne end that wheel 6 connects is placed in the 3rd casing 12, and Cylinder Gear wheel shaft 7 engages with output roller gear 9The other end is placed in the outer upper box of the 3rd casing.
At the boundary of the 3rd casing 12 and upper box 1, Cylinder Gear wheel shaft 7 is provided with the oil for isolatingStrip of paper used for sealing, separates the Bevel Gear Drive of decelerator and column gear transmission independent lubricating.
