Description

Technical Field

[0001] The present invention relates to the technical field of reducers, and in particular to a reducer with a lubrication function. Background Art

[0002] Reducers with lubrication function are usually called "self-lubricating reducers" or "lubricated reducers". This type of reducer design has a built-in lubrication system that can automatically maintain the flow of lubricating oil or grease to reduce friction and wear, improve operating efficiency and service life. Common lubricating reducers are splash lubrication reducers, which splash oil through the rotation of the gears and distribute it to the gear and bearing surfaces. They are suitable for high-speed reducers.

[0003] Patent publication number CN114811012A discloses a steering reducer with a lubrication function. Lubricating oil is injected into the housing, and the lubricating oil flows into the housing through the oil outlet pipe and soaks into the sponge sheet, so that the sponge sheet is in a full state. When the reducer body is working, the vibration of the mechanical movement shakes the full sponge sheet, causing the lubricating oil in the sponge sheet to continuously drip downward, and the oil is continuously replenished to the parts in the reducer body, so that the reducer body can achieve the effect of automatic lubrication inside.

[0004] The prior art has the following defects:

[0005] Unable to maintain uniform lubrication when the input shaft rotates clockwise or counterclockwise: During rotation in different directions, the lubricating oil will be biased to one side due to gravity, centrifugal force or other factors, resulting in uneven lubrication. In particular, when the internal structure design of the device is not suitable for bidirectional operation, the lubrication system will be unable to evenly distribute the lubricating oil in both rotation directions. Therefore, it is necessary to set a lubricating oil flow channel that can flow in both directions to accommodate the input shaft to maintain uniform lubrication when it rotates clockwise or counterclockwise.

[0006] Unable to ensure normal flow of lubricating oil according to the working condition tilt: In the fields of ships, aviation, mining machinery, etc., the equipment will run in a tilted state, resulting in uneven distribution of lubricating oil, increasing the risk of wear and failure. Therefore, it is necessary to set up a multi-angle lubrication system and gravity compensation system to ensure the normal flow of lubricating oil at any angle.

[0007] The loss caused by the large flow space of lubricating oil: Under high-speed operation or high-pressure environment, the loss caused by the large flow space of lubricating oil will lead to the inability of lubricating oil to effectively cover all parts that need lubrication, increasing friction and wear. Therefore, it is necessary to reduce the space for lubricating oil to flow, and then use dripping and spraying methods to reduce oil waste and ensure the lubrication effect. Summary of the invention

[0008] In view of the problems in the prior art, such as the inability to maintain uniform lubrication when the input shaft rotates clockwise or counterclockwise, the inability to ensure normal flow of lubricating oil according to the working conditions, and the excessive flow space of lubricating oil causing loss, a reducer with lubrication function is proposed.

[0014] By adopting the above scheme, the lubricating oil is splashed to the position where the gears rub and drips into the middle guide groove through the rotation of the input pinion and the output gear. The lubricating oil in the middle guide groove flows through the lubricating flow shell. When the input shaft rotates clockwise and the output shaft rotates counterclockwise, the lubricating oil flows out from the middle guide groove to the pinion oil storage tank and the gear oil storage tank, thereby achieving a lubrication cycle.

[0018] Furthermore, the inner walls of the first flow groove and the second flow groove are fixedly connected with a one-way adjustment groove.

[0019] By adopting the above scheme, the input pinion and the output gear rotate, and the input pinion and the output gear rotate accordingly, splashing the lubricating oil to the position where the gears rub and dripping into the middle guide groove.

Conversely, the lubricating oil is sprayed into the small gear oil storage tank through the output guide groove by the oil injection device in the direction of the output large gear for replenishment, thereby achieving lubrication circulation.

[0057] Through the rotation of the input pinion 45 and the output gear 47, the input pinion 45 and the output gear 47 rotate accordingly, splashing the lubricating oil to the position where the gears rub and dripping into the middle guide groove 421. The lubricating oil in the middle guide groove 421 reaches the combined flow groove 414 through the middle flow groove 411, and the adjustment state of the adjustment component 5 is different according to the different rotation directions, so that the lubricating oil flows out from the middle guide groove 421 to the pinion oil storage groove 46 and the gear oil storage groove 48, or flows out through the output guide groove 424 to the pinion oil storage groove 46 and the gear oil storage groove 48.

At the same time, when the input pinion 45 and the output large gear 47 rotate, a small amount of lubricating oil will enter the first guide groove 422 and the second guide groove 423, and then enter the combined flow groove 414 through the first flow groove 412 and the second flow groove 413 for replenishment under the help of the one-way adjustment wheel 55.

[0062] Example 2, reference Fig.10 - Fig.16 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: Fig.10 The inner wall of the lubrication guide inner shell 42 is provided with a plurality of offset grooves 58 , a center of gravity offset block 57 is slidably connected between the inner walls of two offset grooves 58 on the same horizontal line, and a plurality of oil injection devices 59 are fixedly connected to the outer wall of the lubrication guide inner shell 42 .

Under the action of gravity, the lubricating oil flows from the second guide groove 423 through the second flow groove 413 into the combined flow groove 414 with the help of the one-way adjustment wheel 55. At this time, when the input shaft 2 rotates clockwise and the output shaft 3 rotates counterclockwise, the input small gear 45 and the output large gear 47 rotate accordingly, and the center of gravity offset block 57 slides toward the offset groove 58 in the direction of the output large gear 47 under the action of gravity. , so that the lubricating oil first enters the small gear oil storage tank 46 through the middle guide groove 421 for replenishment, so as to achieve lubrication circulation; on the contrary, the lubricating oil is sprayed into the small gear oil storage tank 46 through the output guide groove 424 by the oil spraying device 59 in the direction of the output large gear 47 for replenishment, so as to achieve lubrication circulation. When the housing 1 tilts toward the input shaft 2 according to the working condition, the lubricating oil in the large gear oil storage tank 48 is less, and the lubricating oil in the small gear oil storage tank 46 is more. According to different rotation directions, the lubricating oil enters the large gear oil storage tank 48 through different guide grooves for replenishment, so as to achieve lubrication circulation. The rest of the structure is the same as that of embodiment 1.

[0065] Working principle of the present invention:

[0066] During operation, lubricating oil is added to the pinion oil storage tank 46 and the large gear oil storage tank 48, and the lubricating oil is splashed to the position where the gears rub against each other through the rotation of the input pinion 45 and the output large gear 47 for lubrication, and then the lubricating oil is internally circulated through the lubricating flow outer shell 41, the lubricating guide inner shell 42 and the adjusting component 5 to achieve a uniform lubrication effect.

[0067] When the input shaft 2 rotates clockwise and the output shaft 3 rotates counterclockwise, the input pinion 45 and the output gear 47 rotate accordingly, splashing the lubricating oil to the position where the gears rub and dripping into the middle guide groove 421. The lubricating oil in the middle guide groove 421 reaches the combined flow groove 414 through the middle flow groove 411. However, since the driving shaft 53, the driven gear 56, the transmission belt 52, the gear synchronization wheel 51 and the output gear 47 rotate counterclockwise synchronously, the lubricating oil is blocked outside the driving adjustment groove 415, so that the lubricating oil flows out from the middle guide groove 421 to the pinion oil storage groove 46 and the gear oil storage groove 48, thereby achieving a lubrication cycle.

[0068] When the input shaft 2 rotates counterclockwise and the output shaft 3 rotates clockwise, the input pinion 45 and the output gear 47 rotate accordingly. At this time, the driving adjustment wheel 54 rotates clockwise synchronously with the output gear 47, guiding the lubricating oil from the combined flow groove 414 to the output flow groove 416, and then sprayed out by the oil spraying device 59 through the output guide groove 424 to achieve lubrication circulation. At the same time, when the input pinion 45 and the output gear 47 rotate, a small amount of lubricating oil will enter the first guide groove 422 and the second guide groove 423, and then enter the combined flow groove 414 through the first flow groove 412 and the second flow groove 413 for replenishment under the help of the one-way adjustment wheel 55.

[0069] When the housing 1 tilts toward the output shaft 3 according to the working condition, there is more lubricating oil in the large gear oil storage tank 48 and less lubricating oil in the small gear oil storage tank 46. Under the action of gravity, the lubricating oil enters the combined flow groove 414 from the second guide groove 423 through the second flow groove 413 with the help of the one-way adjustment wheel 55. At this time, when the input shaft 2 rotates clockwise and the output shaft 3 rotates counterclockwise, the input pinion 45 and the output large gear 47 rotate accordingly, and the center of gravity offset block 57 slides toward the offset groove 58 in the direction of the output large gear 47 under the action of gravity, so that the lubricating oil enters the small gear oil storage tank 46 first through the middle guide groove 421 for replenishment, thereby achieving lubrication circulation; on the contrary, the lubricating oil is sprayed into the small gear oil storage tank 46 through the output guide groove 424 by the oil spraying device 59 in the direction of the output large gear 47 for replenishment, thereby achieving lubrication circulation.

[0070] When the housing 1 tilts toward the input shaft 2 according to the working condition, the lubricating oil in the large gear oil storage tank 48 is less, and the lubricating oil in the small gear oil storage tank 46 is more. According to different rotation directions, the lubricating oil passes through different guide grooves into the large gear oil storage tank 48 for replenishment to achieve lubrication circulation.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
