Abstract
The invention relates to a speed changing box with an oil passage. The speed changing box comprises a box body, wherein the box body is provided with a motor shaft hole, a transitional wheel shaft seat and an output shaft hole, centers of which stay on the same straight line; an oil guiding passage is respectively arranged between the motor shaft hole and a transitional wheel shaft seat and between the output shaft hole and the transitional wheel shaft seat, the side wall of the box body is provided with an oil passage corresponding to the oil guiding groove, the oil passage is communicated with the oil guiding passage, an outlet on the outer end of the oil passage is arranged on the outer side surface of the box body, one side of the box body of the speed changing box is provided with an oil passage, the oil passage is convenient for oiling a gear under the situation that the box body is not disassembled, an exhaustion effect also can be realized, the gear can be well lubricated, and the service life of the speed changing box is prolonged.
Description
Technical field
The present invention relates to a kind of gearbox, be specifically related to a kind of gearbox with oil duct.
Background technique
Gearbox needs to gear and bearing oiling in housing in the process using, general oiling method is that gear box is taken apart, after adding oil to gear, fix closed casing again, 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.
Summary of the invention
In order to address the above problem, the present invention 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, the working life of prolongation gearbox.
The present invention is achieved by 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 oil guide slot setting excessively connecting 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 is connected in the unidirectional rubber exhaust valve on breathing pipe top.
The invention has the beneficial effects as follows: 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, the working life of prolongation gearbox.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Accompanying drawing 1 is the structural representation of the gearbox with oil duct.
In figure, 1. casing, 2. output shaft axis hole, 3. excessive 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 1 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 oil guide slot 5 excessively connecting between axle block 3 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 is connected in the unidirectional rubber exhaust valve on breathing pipe top.
When use, gearbox assembling is shaped and is connected with sedan-chair after car body, and the external port of guarantee 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.
