Definitions
- the invention relates to a transmission arrangement according to the preamble of claim 1, a method according to claim 8 and a method according to claim 9.
- An oil circuit of a wind turbine gearbox usually has an internal and an external part.
- the external part is characterized by being outside of a gearbox housing.
- the internal part is located within the gearbox housing accordingly. Outside the transmission housing, that is, in the external part, components are arranged that must be accessible for maintenance purposes.
- Lubrication points of the gearbox such as bearings or toothing, are located inside the gearbox and are therefore part of the internal part of the oil circuit.
- the object of the invention is to prevent increased wear or damage occurring as a result of the infiltrated dirt.
- a gear assembly refers to an assembly that includes a gear.
- the arrangement also includes an oil circuit.
- This is an arrangement of one or more oil lines. These are connected to one another in an oil-conducting manner in such a way that the oil circulates in the oil circuit.
- the oil circuit preferably has a pump that conveys the oil through the oil circuit.
- At least one lubricating point is integrated into the oil circuit. This is lubricated by the oil circulating in the oil circuit.
- the lubrication point is preferably arranged inside a transmission housing.
- the lubrication point is, for example, a bearing or the toothing of a gear wheel.
- the transmission arrangement comprises at least one directional control valve with at least two switching positions and at least three connections, preferably with exactly two switching positions and/or exactly three connections. If the directional control valve is in a first switching position, it connects the first connection and the third connection to one another in an oil-conducting manner. In the first switching position, the second connection is separated from the first connection and the third connection. In the first switching position, there is neither an oil-conducting connection between the first connection and the second connection nor between the second connection and the third connection within the directional control valve
- the directional control valve connects the first connection and the second connection to one another in an oil-conducting manner.
- the third connection is separated from the first connection and the second connection.
- the lubricating point and the second connection are connected to one another in an oil-conducting manner.
- the lubrication point can be integrated into the oil circuit via the second connection. Oil that circulates through the oil circuit is routed from the second connection to the lubrication point via a corresponding oil-conducting connection.
- the lubrication point and the third connection are not connected to one another in an oil-conducting manner. This means that oil from the third connection cannot get to the lubrication point, but is routed past the lubrication point.
- a corresponding oil line referred to below as a bypass, which can be connected to the third connection in an oil-conducting manner, bypasses the lubrication point.
- the first switching position of the directional control valve corresponds to a flushing position.
- the second switching position corresponds to an operating position. If the directional control valve is placed in the flushing position, the oil in the oil circuit circulates via the bypass so that the lubrication point is bypassed. Possible impurities that are ZFwO 2023/016717än AG PCT/EP2022/069024 Friedrichshafen are in the oil circuit and cannot get into the lubrication point and damage it.
- the impurities can be removed from the oil circuit. It is then possible to switch to the operating position so that the lubricating point is integrated into the oil circuit and supplied with oil via the second connection.
- the same pump is preferably used as in the flushing position. This is advantageous because the assembly can be flushed with the transmission's operating pump. It is not necessary to integrate a separate pump into the oil circuit for flushing.
- the third connection is not only connected in an oil-conducting manner to the above-mentioned lubricating point, but also to no other lubricating point. This ensures that no lubrication point is damaged by contaminants when the directional control valve is in the flushing position.
- the transmission arrangement is preferably further developed with at least one component which is integrated into the oil circuit and is connected to the first connection in an oil-conducting manner.
- at least one oil-conducting connection connects the component and the first connection to one another in an oil-conducting manner.
- the oil circulating in the oil circuit then flows from the component to the first connection.
- the component is, for example, a pump, an oil filter, an oil cooler or a line pipe.
- the transmission arrangement is preferably further developed in such a way that the top component is arranged outside of the transmission housing. This makes the component easily accessible so that it can be easily repaired or replaced.
- An oil circuit preferably also includes an oil sump.
- This is an oil reservoir, that is, a container for collecting oil, from which the oil circuit is fed.
- the oil is preferably from a pump - such as the one mentioned at the beginning ZFwO 2023/016717än AG PCT/EP2022/069024 Friedrichshafen
- the third connection is connected to the oil sump in an oil-conducting manner.
- oil that emerges from the directional control valve via the third connection flows into the oil sump, bypassing the at least one lubrication point.
- the third connection is connected to a dirty oil container in an oil-conducting manner.
- the dirty oil tank is used to collect oil for disposal.
- the oil circuit is not fed from the dirty oil container.
- the dirty oil container is therefore different from the oil sump.
- the dirty oil container is preferably arranged outside of the transmission housing. This has the advantage that the dirty oil container can be easily removed to dispose of the oil in it.
- a method according to the invention serves to flush the transmission arrangement according to the invention or a preferred development.
- the method provides that the directional control valve is transferred to the first switching position. While the directional control valve is in the first switching position, oil circulates in the oil circuit. This is preferably done with the operating pump of the transmission. Any impurities present in the oil circuit are flushed out, bypassing the at least one lubricating point.
- the directional control valve is then switched to the second switching position.
- the oil circulating in the oil circuit then passes through the at least one lubricating point so that the transmission can be put into operation.
- Another method according to the invention serves to repair the transmission arrangement according to the invention or a preferred development.
- the component mentioned at the beginning is removed in order to then repair or replace it.
- the repaired or replaced additional component is ZFwO 2023/016717än AG PCT/EP2022/069024
- the gear assembly is now flushed using the method described above.
- the directional valve is thus transferred to the first switching position before oil circulates through the oil circuit.
- the directional control valve is then switched to the second switching position.
- FIG. 1 A preferred embodiment of the invention is shown in FIG. 1 in detail shows:
- the transmission arrangement 101 shown in Figure 1 comprises a transmission 103 and a lubricant supply device 105.
- Gears 109 are arranged in a housing 107 of the transmission 103 .
- Bearing 111 for supporting the gears 109 or shafts on which the gears 109 are arranged, and teeth of the gears 109 form lubrication points.
- the lubrication points are supplied with oil using the lubricant supply device 105 .
- the housing 107 forms an oil sump from which oil is introduced into the lubricant supply device 105 via an interface 113 .
- the lubricant supply device 105 has a pump 115 for conveying the oil.
- Filters 117 serve to filter out impurities from the oil.
- an oil cooler 119 is integrated into the lubricant supply device 105 .
- the lubricant supply device 105 is arranged outside of the housing 107 . As a result, the components of the lubricant supply device 105 are easily accessible for repair and maintenance work. ZFwO 2023/016717än AG PCT/EP2022/069024
- a switchable directional control valve 121 is provided to prevent damage to the lubrication points due to contamination. This has a first connection 121a, a second connection 121b and a third connection 121c.
- Oil from the lubricant supply device 105 enters the directional control valve 121 via the first connection 121a. Depending on the switching position of the directional control valve 121, the oil exits from the second connection 121b or from the third connection 121c.
- the directional control valve 121 is switched in such a way that the oil exits from the second connection 121b.
- the second connection 121b is connected to the lubricating points of the transmission 103 in an oil-conducting manner. The lubrication points are thus supplied with oil during normal operation via the second connection 121b.
- the directional control valve 121 is switched over in order to implement a rinsing operation.
- the oil then no longer exits via the second connection 121b, but via the third connection 121c.
- the oil emerging from the third connection 121c does not reach the lubricating points of the transmission 103, but flows around them.
- Corresponding bypasses 123a, 123b are shown in FIG. 1, which can be realized alternatively or in combination.
- a first bypass 123a runs inside the housing 107. Oil that is drained via the first bypass 123a flows directly into the oil sump. From here it reaches the lubricant supply device 105 and is filtered there. Because the oil is circulated via the lubricant supply device 105 and the first bypass 123a, the impurities can be filtered out.
- a second bypass 123b directs the oil into a container 125.
- the oil collected in container 125 can be removed and replaced with fresh oil.
