Embodiment
In order to make technical problem solved by the invention, technological scheme and beneficial effect clearly understand, below in conjunction with drawings and the embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1-Figure 3, the lubrication system of the speed changer of one embodiment of the present invention, described speed changer comprises housing, multiple parts to be lubricated and the rotatingshaft installed in the housing, the bottom of described housing fills lubricant oil, wherein, described lubrication system comprises: with the oil pump 1 of described rotatingshaft synchronous axial system and the lubrication runner to the parts fuel feeding to be lubricated in speed changer, described lubrication runner is provided with multiple oil outlet, each oil outlet is opened in the relevant position of each parts to be lubricated respectively and described lubricant oil can flow to each parts to be lubricated from described outlet, the described entrance of oil pump 1 and the lubricant oil of housing bottom pass through pipeline connection, outlet and the lubrication flow passage of described oil pump 1.
Parts to be lubricated typically refer to the parts such as gear, bearing, clutch in speed changer, but are not limited to these parts above-mentioned, have different parts to be lubricated in dissimilar speed changer, and in each speed changer, the quantity of parts to be lubricated is different.
As one preferred embodiment, described lubrication system also comprises the first one-way valve 2, and the outlet of described oil pump 1 is communicated with the entrance of the first one-way valve 2, outlet and the lubrication flow passage of the first one-way valve 2.The effect arranging the first one-way valve 2 is to prevent the oil return lubricated when oil pump 1 does not turn or reverses in runner.
One-way valve is a kind of parts of industrial frequent use, can only one-way conduction, one-way valve comprises an entrance and an outlet, one-way valve inside is provided with spring, the outside fluid with certain pressure flows to one-way valve from entrance, overcomes the resistance of spring, flows out from outlet, but reverse flow is then not all right, namely external fluid can not flow to one-way valve from outlet and flow out from entrance.
As one preferred embodiment, described lubrication system also comprises the second one-way valve 3, and the entrance of described second one-way valve 3 and the lubricant oil of housing bottom pass through pipeline connection, the described outlet of the second one-way valve 3 and the outlet of oil pump 1.During real work, described rotatingshaft may reverse (such as this speed changer is used on automobile, during back of automobile), due to oil pump 1 and described rotatingshaft synchronous axial system, therefore oil pump 1 also may reverse, due to the existence of the first one-way valve 2, can not oppositely oil suction when oil pump 1 reverses, if therefore there is no the second one-way valve 3, oil pump 1 dallies when reversing always, the damage of oil pump 1 or other associated components can be caused, by arranging the second one-way valve 3, when oil pump 1 reverses by the second one-way valve 3 from housing bottom oil suction, the lubricant oil drawn flows back to housing bottom by oil pump 1 again, the idle running avoiding oil pump 1 and the injury to other parts caused thus.
As one preferred embodiment, described lubrication system also comprises pressure regulator valve 4, described pressure regulator valve 4 comprises: entrance 402, first exports 403 and second and exports 404, the entrance 402 of pressure regulator valve 4 and the outlet of the first one-way valve 2, first outlet 403 passes through pipeline connection with lubrication flow passage, the second outlet 404 with the lubricant oil of housing bottom.
The working principle of pressure regulator valve 4 is as described below: when the pressure of the lubricant oil at entrance 402 place of pressure regulator valve 4 is less or without pressure, and described entrance 402 and first exports 403 and second and exports 404 not conductings, and namely pressure regulator valve 4 cuts out; When the pressure increase of the lubricant oil at entrance 402 place of pressure regulator valve 4 is to the first setting value, described entrance 402 and first exports 403 conductings; When the pressure increase of the lubricant oil at entrance 402 place of pressure regulator valve 4 is to the second setting value, described entrance 402 and first exports 403 and second and exports 404 all conductings.First setting value is less than the second setting value, and described first setting value is between 0.1MPa-0.3MPa, and described second setting value is between 0.6MPa-1MPa, and preferably, the first setting value is 0.2MPa, and the second setting value is 0.8MPa.Pressure regulator valve is existing product, and concrete structure no longer describes in detail.
The effect arranging pressure regulator valve 4 is to make the lubricant oil at lubrication runner place keep constant pressure, because when the pressure increase of the lubricant oil at entrance 402 place of pressure regulator valve 4 is to the second setting value, having parts of lubricating oil is back to housing bottom from the second outlet 404, the lubricant oil at the first outlet 403 place (namely lubricating runner place) is made to keep constant pressure with this, the pressure making the lubricant oil in lubrication runner keep constant, realizes stable lubrication.In real work, the rotating speed of described rotatingshaft is not constant, and therefore the working state of oil pump 1 is also unfixed, and the pressure of the lubricant oil in the first one-way valve 2 outlet port neither be constant, by arranging pressure regulator valve 4, make the working state that this lubrication system keeps stable.
Be communicated with because lubrication runner and first exports 403, and the outlet of lubrication runner and the first one-way valve 2, therefore lubricant oil both can flow directly to lubrication runner from the first one-way valve 2, also flow in lubrication runner by pressure regulator valve 4.
In order to make the lubricant oil entering into oil pump 1 comparatively clean, in the connecting pipeline between the entrance and the lubricant oil of housing bottom of oil pump 1, be provided with filter 15.
