Abstract
The utility model relates to a speed changing box with an oil duct. The speed changing box comprises a box body, wherein a motor shaft hole, a transition wheel shaft seat and an output shaft hole are formed in the box body, and centers of the motor shaft hole, the transition wheel shaft seat and the output shaft hole are positioned on the same straight line. The motor shaft hole and the output shaft hole are respectively connected with the transition wheel shaft seat through oil guide grooves, the oil duct is formed in the lateral wall of the box body and corresponding to the oil guide grooves and communicated with the oil guide grooves, and the outlet in the outer end of the oil duct is positioned in the outer lateral surface of the box body. The oil duct is formed in one side of the box body of the speed changing box, can feed oil to a gear conveniently without disassembling the box body, and has a function of exhausting gas, therefore, the gear can be lubricated well, and service life of the speed changing box can be prolonged.
Description
Technical field
The utility model relates to a kind of gearbox, is specifically related to a kind of gearbox with oil duct.
Background technique
Gearbox needs to gear and bearing oiling in housing in the process of using, general oiling method is that gear box is taken apart, after adding oil to gear, again casing closure is fixed, but this method operation is very inconvenient, fragile casing, and in the process of closed casing, gear oil easily leaks, affect the lubrication effect of gear.Meanwhile, because gearbox is in sealing state, it can produce gas at work, and gas accumulates in casing and cannot discharge, and can shorten the working life of gearbox.
Model utility content
In order to address the above problem, the utility model proposes a kind of gearbox with oil duct, casing one side of this gearbox is provided with oil duct, this oil duct is convenient to refuel to gear in the situation that not taking casing apart, and can also play the effect of exhaust, better oilgear, extends working life of gearbox.
The utility model is achieved through the following technical solutions: a kind of gearbox with oil duct, comprise casing, and described casing is provided with motor shaft axis hole, excessive axle block and the output shaft axis hole that the center of circle is located along the same line; Motor shaft axis hole, output shaft axis hole are connected with oil guide slot respectively and between excessive axle block, and the corresponding oil guide slot of sidewall of described casing is provided with oil duct, and this oil duct is communicated with oil guide slot, and the outlet of the outer end of oil duct is positioned at casing outer side surface.
The corresponding output shaft axis hole of described oil duct and the excessively oil guide slot setting between axle block.
The oil duct junction of described oil duct is provided with internal thread, and oil duct blocking device can be rotatably connected.
Described oil duct blocking device comprises and is provided with externally threaded breathing pipe, and the unidirectional rubber exhaust valve that is connected in breathing pipe top.
The beneficial effects of the utility model are: a kind of gearbox with oil duct, casing one side of this gearbox is provided with oil duct, and this oil duct is convenient to refuel to gear in the situation that not taking casing apart, and can also play the effect of exhaust, better oilgear, extends working life of gearbox.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the structural representation with the gearbox of oil duct.
In figure, 1. casing, 2. output shaft axis hole, 3. excessively axle block, 4. motor shaft axis hole, 5. oil guide slot, 6. oil duct, 7. oil duct blocking device.
Embodiment
In the accompanying drawings, a kind of gearbox with oil duct, comprises casing 1, and described casing 1 is provided with motor shaft axis hole 4, excessive axle block 3 and the output shaft axis hole 2 that the center of circle is located along the same line; Respectively and between excessive axle block 3, be connected with oil guide slot 5, the corresponding oil guide slot 5 of sidewall of described casing 1 is provided with oil duct 6 for motor shaft axis hole 4, output shaft axis hole 2, and this oil duct is communicated with oil guide slot 5, and the outer end of oil duct 6 exports and is positioned at casing 1 outside.
The corresponding output shaft axis hole 2 of described oil duct 6 and the excessively oil guide slot between axle block 35 arrange.
The oil duct junction of described oil duct 6 is provided with internal thread, and oil duct blocking device 7 can be rotatably connected.
Described oil duct blocking device 7 comprises and is provided with externally threaded breathing pipe, and the unidirectional rubber exhaust valve that is connected in breathing pipe top.
During use, gearbox assembling is shaped and is connected with sedan-chair after car body, and the external port of assurance oil duct 6 upward, can prevent that the oil leakage in gearbox from going out; Oil duct blocking device 7 is connected with oil duct 6 simultaneously, can prevents that dust from entering in gearbox, do not affect again the exhaust effect of gearbox; When needs are when refueling in gearbox, oil duct blocking device 7 is screwed off, by oil duct 6, oil is injected in gearbox, now, lubricant oil can be along oil guide slot 5 flow direction motor axle axis holes 4, output shaft axis hole 2 and excessive axle block 3, and realization is oily to gear, and can not make oil leak outside.Oil duct blocking device 7 can prevent that dust from entering that casing 1 is interior affects speed changer work.
