As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.
As described in the background art, the following problems exist in the prior art:
during the operation of the speed reducer, the gears inevitably have failure modes such as abrasion, pitting and the like. These problems occur in part due to the meshing load between the teeth and in part due to the quality of the oil. At present, a widely adopted lubricating mode is splash lubrication, because the lubricating oil contains impurities and small metal particles generated by mechanical abrasion, in the process of lubricating the gear, the impurities damage an oil film, so that the abrasion of the tooth surface of the gear is aggravated, the pitting of the tooth surface is formed, the joint surface is scratched, and the service life of the gear is reduced. The traditional impurity removing method is to add a purifying device, so that impurities in oil are reduced to a great extent, the quality of the oil is guaranteed, the cost is increased, and the working reliability of the speed reducer is reduced.
In order to solve the technical problems, the application provides the splash lubrication self-cleaning speed reducer oil tank, and the separator is added in the tank body on the basis of ensuring the original structure of the oil tank, so that impurities automatically leave a splash lubrication working area by utilizing the difference of oil and impurity density, and the purpose of self cleaning is achieved.
In one exemplary embodiment of the present application, as shown in fig. 1, the present application includes a vertical partition, an inclined partition, a connection floor, and a case; the upper part and the lower part of the box body are respectively provided with an oil inlet and an oil outlet, a plurality of vertical partition plates which are connected into a whole are arranged in the side wall of the box body, grooves are formed between the vertical partition plates and the side wall of the box body, gaps for connecting the thickness of the bottom plate are formed between the bottoms of the partition plates and the bottom of the box body, and the grooves are mutually communicated at the bottom of the box body; the inner side of the vertical partition plate is provided with a plurality of inclined partition plates inclined according to a set angle, and a labyrinth is formed among the inclined partition plates; a groove formed by inclined surfaces at the bottom of the box body;
lubricating oil is injected into the oil tank through the oil inlet hole 1, and the injected oil is immersed at a certain distance at the bottom of the oversized gear. For the original high-density impurities in the lubricating oil or the high-density impurities generated in the running process, the impurities can be guided to the bottom of the oil tank through the inclined baffle plate 6, the inclined angle between the inclined baffle plate 6 and the horizontal direction is 15-30 degrees, and the inclined baffle plate is soaked in the lubricating oil, so that the impurities in the lubricating oil can smoothly slide down the bottom of the oil tank along the inclined baffle plate 6, and the impurities which are sunk to the bottom of the oil tank can be prevented from being brought into an upper clean oil layer by vortex generated when the gear 4 rotates. And a sufficient distance is reserved between the first inclined partition plate and the gear, so that the partition plate is prevented from being sucked up by the suction force generated by the gear rotating at a high speed to cause accidents. The length of the first baffle plate must exceed the vertical plane of the meshing position of the gears by a certain distance, so that the baffle plate can better play a role.
The specific process is as follows:
in the oil tank filled with a certain amount of lubricating oil, for low-density impurities, the impurities tend to be thrown to the top surface of the oil tank by a gear in the splash lubrication process, fall into a groove between the vertical partition plates and the side wall of the tank along the inner wall, float on the top surface of the groove, and because the welding seams among the vertical partition plates are not leaked, the bottoms of the partition plates are communicated everywhere, and the impurities do not have the opportunity to participate in the lubrication of the speed reducer; for high-density impurities, the impurities can automatically fall to the bottom of the labyrinth along the inclined plane under the action of dead weight, and the impurities falling to the bottom of the labyrinth fall to the bottom of the oil tank in the splashing lubrication process, so that the impurities can not easily run out from the bottom of the labyrinth to participate in lubrication. The lubricating oil containing impurities, which stays at the bottom of the oil tank, can roll and slide to the oil drain plug along the inclined surface at the bottom, the oil drain plug is opened periodically, and the impurities are discharged, so that the lubricating oil which really participates in work is relatively clean lubricating oil.
The gap positions between the inclined partition plates inclined at a certain angle are alternately arranged at the middle position and the side surface position of the oil tank to form a labyrinth, so that high-density particles or impurities falling into the labyrinth are not opportune to participate in lubrication of the speed reducer; in fig. 1, taking three inclined partition plates as an example, a first inclined partition plate 6-1 is positioned on a left vertical partition plate wall, a second inclined partition plate 6-2 is positioned on a right vertical partition plate wall, the position of the second inclined partition plate 6-2 is slightly lower than that of the first inclined partition plate 6-1, and a gap is formed between the first inclined partition plate and the second inclined partition plate at the central line of the oil tank; the third inclined partition plate 6-3 is positioned on the left vertical partition plate wall, and a gap is formed between the third inclined partition plate 6-3 and the right vertical partition plate.
When the gear rotates at a high speed, low-density impurities at the top of the lubricating oil liquid level can be thrown to the top of the oil tank, slide into a gap groove between the vertical partition plate 5 and the wall of the oil tank along the inner wall, and the vertical partition plate is 50-120 mm higher than the lubricating oil liquid level, so that the splashed oil can smoothly enter the bottom of the oil tank. The distance between the vertical partition 5 added in the tank and the tank wall is 20-100 mm, and the excessive increase of the tank volume is not caused.
Because the groove 2 is formed by the inclined surface at the bottom, when the oil containing impurities reaches the bottom of the oil tank, the impurities can slide to the oil plug 3 along the groove under the action of dead weight, so that the oil plug 3 can be opened regularly to discharge the oil containing the impurities.
If the partition board in the oil tank is directly welded to the oil tank, impurities can be attached to the wall of the oil tank and the added partition board after the oil tank is used for a long time, and the traditional method can be difficult to clean. So can adopt the mode as shown in figure 3, weld oblique baffle, connection bottom plate and vertical baffle into a whole, then through the screw hole on the connection bottom plate with screw connection to the bottom of reduction gear oil tank, so not only easy to assemble, dismantle, it is also more convenient to wash.

The distance between the vertical partition plate and the wall of the oil tank is 20-100 mm, and the vertical partition plate is 50-120 mm higher than the liquid level of lubricating oil, so that splashed oil can smoothly enter a working area, excessive increase of the volume of the oil tank is avoided, low-density impurity oil which is splashed to the top of the oil tank through splash lubrication falls into a groove between the vertical partition plate and the side wall of the tank body along the inner wall of the oil tank, and because welding seams among the vertical partition plates are not leaked, the bottoms of the partition plates are communicated everywhere, the low-density impurity floats on the top surface of the groove, and no opportunity exists to flow into the splash area to participate in the lubrication of the speed reducer.
The included angle between the inclined partition boards and the horizontal plane direction is generally 15-30 degrees, and the gap positions between the inclined partition boards inclined at a certain angle are alternately arranged at the middle position and the side positions of the oil tank to form a labyrinth, so that impurities in lubricating oil can smoothly roll to the bottom of the oil tank along the inclined partition boards under the action of dead weight, and the impurities which are sunk to the bottom of the oil tank can be prevented from being brought into an upper clean oil layer by vortex generated when the gears rotate.
The bottom is the recess that the inclined plane formed, and when the oil that contains impurity reached the oil tank bottom, impurity can drop to the oil plug department along the recess, just so can open the oil plug regularly, emits the oil that contains impurity.
