Description

Technical Field

[0001] The utility model belongs to the technical field of constant-position oil cups, and particularly relates to an adjustable constant-position oil cup. Background Art

[0002] Currently, most thin oil lubricated rotating equipment uses a constant level oil cup for oil replenishment to keep the lubricating oil in the rotating equipment within the designed range. It can also act as a window to determine whether lubricating oil needs to be added based on the oil level in the constant level oil cup.

[0003] During the operation of rotating equipment, the lubricating oil in the bearing chamber will be consumed. The drop in the oil level in the bearing chamber will cause the air pressure balance on the lubricating oil liquid surface in the constant-level oil cup to be destroyed. The lubricating oil stored in the constant-level oil cup will flow into the bearing chamber. After the oil level in the bearing chamber rises, the air pressure will eventually be balanced again. Therefore, the constant-level oil cup can automatically replenish oil after the oil level in the bearing chamber drops, so that the oil level in the bearing chamber is always maintained at the designed oil level.

[0004] Although the constant-level oil cup is suitable for most oil bath lubrication or splash lubrication equipment, it also has some disadvantages. For example, the design standard oil level of the constant-level oil cup (i.e., the oil filling level) is fixed and cannot be adjusted. In actual application scenarios, there are situations where the height position of the lubricated parts changes slightly after repair or maintenance. If the oil filling level is not adjusted, it will affect the effective lubrication of the lubricated parts.

[0005] Therefore, how to adjust the height of the designed standard oil level according to the position of the parts to be lubricated is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0041] The core of the utility model is to provide an adjustable constant-level oil cup so as to adjust the height of the designed standard oil level according to the position of the part to be lubricated.

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] After some parts of the rotating equipment that needs lubrication have been replaced or adjusted, there will be slight changes in the position of the parts to be lubricated (such as bearings), but the position of the rotating equipment for installing the constant-position oil cup cannot be adjusted. This results in the design standard oil level of the constant-position oil cup (i.e., the oil replenishment level) being fixed, so that the constant-position oil cup can no longer meet the designed oil replenishment requirements after a slight change in the position of the parts to be lubricated, which will cause the oil level in the rotating equipment to be too high or too low.

[0044] Based on the above problems, the utility model discloses an adjustable constant-position oil cup, which can adjust the oil filling level according to the actual situation to ensure that the oil level in the rotating equipment is kept within a suitable range, and avoid the problem that the oil level in the rotating equipment cannot meet the lubrication requirements after a slight change in the position of the lubricated parts. The adjustable constant-position oil cup includes an oil cup base 104, an oil cup body 101 and an adjustment bracket.

[0045] Among them, the oil cup base 104 is a cavity with an opening at the top, and the lower end of the oil cup base 104 is connected to a transverse branch pipe 108, which is used to connect to the equipment to be lubricated. Usually, an oil replenishing interface is provided at the corresponding position of the equipment to be lubricated, and the transverse branch pipe 108 is sealed and connected to the oil replenishing interface to realize the connection between the adjustable constant-level oil cup and the equipment to be lubricated, so as to realize oil replenishment as the oil level of the equipment to be lubricated drops, thereby ensuring that the oil level of the equipment to be lubricated is always maintained at the designed standard oil level.

[0046] The oil cup body 101 is used to store lubricating oil, and the lower end of the oil cup body 101 is connected to the lower branch pipe 103, and the bottom of the lower branch pipe 103 is a wedge-shaped opening 1031. The angle between the wedge-shaped opening 1031 and the axis of the lower branch pipe 103 can be designed to be 25°-40°, for example, 30°. Those skilled in the art can design the angle of the wedge-shaped opening 1031 according to needs, and the utility model is not limited to the above angle range.

[0047] The oil cup body 101 can be designed as a glass cover structure to facilitate observation of the oil level of the lubricating oil in the oil cup body 101 . Before installing the oil cup body 101 to the oil cup base 104 , the oil cup body 101 should be filled with lubricating oil, and then the oil cup body 101 should be installed to the oil cup base 104 .

[0048] The adjustment bracket is arranged in the oil cup base 104, and the adjustment bracket includes a support plate 109 which is adjustable in height, and the bottom of the lower branch pipe 103 is supported on the support plate 109. The setting height of the support plate 109 is adjustable, and when the oil cup body 101 is installed on the oil cup base 104, the bottom of the lower branch pipe 103 is supported on the support plate 109, so the height of the support plate 109 can affect the setting height of the lower branch pipe 103, that is, the height of the wedge-shaped opening 1031.

[0049] Those skilled in the art can understand that when the adjustable constant-level oil cup is installed on the equipment to be lubricated, the oil cup base 104 and the equipment to be lubricated are in a communicating vessel structure, that is, the oil level in the equipment to be lubricated is equal to the oil level in the oil cup base 104. When the oil cup body 101 filled with lubricating oil is installed on the oil cup base 104, the lubricating oil in the oil cup body 101 will flow into the oil cup base 104 through the lower branch pipe 103 under the action of gravity, so that the oil level in the equipment to be lubricated rises. When the oil level rises to the highest point of the wedge-shaped opening 1031 of the lower branch pipe 103 and is sealed by the oil level, the lubricating oil in the oil cup body 101 stops flowing downward.

[0050] Since part of the lubricating oil in the oil cup body 101 flows out, the pressure in the oil cup body 101 is lower than the external atmospheric pressure. Since the highest point of the wedge-shaped opening 1031 is also sealed by the oil level, the external air cannot enter the oil cup body 101 through the wedge-shaped opening 1031, so that the pressure in the oil cup body 101 is always lower than the external atmospheric pressure, and the oil level in the lubricating device is maintained at the designed standard oil level, that is, the oil level corresponding to the highest point of the wedge-shaped opening 1031. As the lubricating oil in the lubricated device is consumed, the oil level in the lubricated device drops to below the highest point of the wedge-shaped opening 1031, and the external air can enter the oil cup body 101 through the wedge-shaped opening 1031, so that the pressure in the oil cup body 101 is equal to the external atmospheric pressure, and the lubricating oil in the oil cup body 101 will flow into the lubricated device under the action of gravity, so that the oil level in the lubricated device continues to rise to the designed standard oil level, and the highest point of the wedge-shaped opening 1031 is sealed by the oil level, so that the oil level in the lubricating device can always be maintained at the designed standard oil level.

[0051] The designed standard oil level in the lubricated equipment, that is, the position of the highest point of the wedge-shaped opening 1031, can be adjusted by the setting height of the support plate 109. Specifically, when in use, the setting height of the support plate 109 needs to be adjusted to the corresponding position first, and then the adjustment bracket is installed in the oil cup base 104. The oil level adjustment scheme provided by the utility model is relatively convenient to adjust, and will not affect the external structure of the adjustable constant position oil cup. It only needs to build an adjustment bracket in the oil cup base 104. Therefore, there will be no problems of lubricating oil leakage and lubricating oil contamination due to the external setting of the adjustment part and the penetration into the oil cup base 104.

[0052] In a specific embodiment of the utility model, the support plate 109 is adjusted in the height direction by adjusting the adjusting member of the bracket. In this embodiment, the adjusting member includes an adjusting rod and an adjusting block sleeved on the adjusting rod, and the support plate 109 is connected to the adjusting block. The adjusting block is sleeved on the adjusting rod, and the adjusting block can be located at different heights of the adjusting rod, thereby adjusting the height of the support plate 109. The matching relationship between the adjusting block and the adjusting rod can be arbitrary, for example, it can be a thread matching relationship, or it can be a clearance matching relationship, and the height of the support plate 109 can be adjusted by the thickness of the adjusting block. The change in the thickness of the adjusting block can be obtained by stacking multiple sub-adjustment blocks, or by selecting an adjustment block with a corresponding thickness.

[0053] Taking the example of the adjustment block and the adjustment rod being threadedly matched, the adjustment member is a threaded adjustment member, the adjustment rod is the adjustment screw 105, and the adjustment block is an adjustment nut 107 threadedly matched with the adjustment screw 105. In this embodiment, the threaded adjustment member is used, so that the adjustment bracket is easier to obtain and manufacture, and the matching of the adjustment nut 107 and the adjustment screw 105 can achieve stepless height adjustment, so the adjustment screw 105 can be adjusted to any height, with a large adjustment range.

[0054] The support plate 109 is sleeved on the adjusting screw 105 and is located above the adjusting nut 107. The support plate 109 can be loosely matched with the adjusting screw 105, and only a hole that matches the adjusting screw 105 needs to be opened on the support plate 109. It should be noted that the hole on the support plate 109 needs to be smaller than the circumscribed circle of the adjusting nut 107 to avoid the adjusting nut 107 being unable to support the support plate 109.

[0055] The adjustment of the design standard oil level of the equipment to be lubricated can be understood as the adjustment of the height of the support plate 109. If the design standard oil level is adjusted upward, the height of the support plate 109 needs to be adjusted upward; correspondingly, if the design standard oil level is adjusted downward, the height of the support plate 109 needs to be adjusted downward. The height of the support plate 109 can be adjusted outside the oil cup base 104, and the adjustment nut 107 is rotated so that the adjustment nut 107 is located at the corresponding height, and then the support plate 109 is sleeved on the adjustment screw 105 to complete the adjustment.

[0056] In this embodiment, the support plate 109 and the adjusting nut 107 can be designed as a split structure, and the support plate 109 is supported on the adjusting nut 107, that is, the adjusting nut 107 and the support plate 109 are successively installed on the adjusting screw 105, and the support plate 109 is supported by the adjusting nut 107 to achieve the fixation of the support plate 109 at the corresponding height of the adjusting screw 105.

[0057] The support plate 109 and the adjusting nut 107 may also be connected together, for example, the support plate 109 may be fixed on the adjusting nut 107, or the support plate 109 and the adjusting nut 107 may be designed as an integrated structure. The support plate 109 and the adjusting nut 107 are connected in a fixed manner, specifically by welding or by fasteners. In the manner in which the support plate 109 and the adjusting nut 107 are connected together, when the adjusting nut 107 is rotated, the support plate 109 follows the adjusting nut 107 to perform a lifting action.

[0058] It should be noted that the support plate 109 can be arranged above the adjusting nut 107, or can be located on the outside or bottom of the adjusting nut 107. When the support plate 109 is arranged on the outside or bottom of the adjusting nut 107, the support plate 109 can be fixed on the adjusting nut 107 or designed as an integrated structure with the adjusting nut 107.

[0059] In another embodiment of the utility model, the adjustment rod can also be a light bar adjustment member, and the adjustment block is a plurality of gauge blocks with a preset thickness sleeved on the light bar adjustment member. By different numbers of gauge blocks sleeved on the light bar adjustment member, the height of the support plate 109 supported above the gauge block can be adjusted. It should be noted that the preset thickness of the gauge block can be different, for example, there are gauge blocks with a thickness of 5 mm and gauge blocks with a thickness of 1 mm. Those skilled in the art can make gauge blocks of corresponding thickness according to demand to increase the adjustment range.

[0060] In order to facilitate the installation of the adjustment bracket in the oil cup base 104, in this embodiment, the adjustment bracket further includes a bracket base 106, the bottom of the adjustment rod is fixed on the bracket base 106, and there is a gap between the bracket base 106 and the side wall of the oil cup base 104. It should be noted that in order to ensure that the adjustment rod is parallel to the axis of the oil cup base 104 after the adjustment bracket is installed, the adjustment rod can be designed to be perpendicular to the bracket base 106. There is a gap between the bracket base 106 and the side wall of the oil cup base 104, which can facilitate the installation between the adjustment and can also prevent the bracket base 106 from blocking part of the oil passage of the horizontal branch pipe 108.

[0061] It is understood by those skilled in the art that the support plate 109 needs to have a certain area in order to support the lower branch pipe 103. The presence of a larger support plate 109 will inevitably block the lubricating oil in the oil cup body 101 from flowing into the oil cup base 104 through the lower branch pipe 103. In order to reduce the blocking effect of the support plate 109 on the lubricating oil, in this embodiment, the support plate 109 is provided with a plurality of oil holes that penetrate the wall thickness, so that the lubricating oil above the support plate 109 can directly flow into the bottom of the support plate 109 through the oil holes, avoiding the situation that the lubricating oil can only flow to the bottom of the support plate 109 through the gap between the support plate 109 and the oil cup base 104.

[0062] In order to facilitate the connection between the horizontal branch pipe 108 and the equipment to be lubricated, the horizontal branch pipe 108 can be provided with a flexible joint, which is connected to the oil filling interface of the equipment to be lubricated through the flexible joint, which has the technical effect of convenient connection and easy sealing. The horizontal branch pipe 108 can be welded to the oil cup base 104 by plug welding.

[0063] The adjustment of the adjustment bracket needs to be tested repeatedly until the height of the support plate 109 meets the oil level adjustment requirements. For example, when the oil level of the equipment to be lubricated cannot meet the lubrication requirements of the rotating parts, the oil level needs to be raised, and the height of the support plate 109 can be adjusted upward. After adjusting one end distance according to experience, test whether the oil level of the equipment to be lubricated can meet the lubrication requirements, that is, the oil level is neither too high nor too low, and is within the standard range. Since the height of the support plate 109 is adjusted based on experience, it usually takes multiple adjustments to adjust the height of the support plate 109 to a suitable position.

[0064] Based on this, in this embodiment, an oil level adjustment scale mark is provided on the adjustment rod. It should be noted that the oil level adjustment scale mark can be used to indicate the height corresponding to the highest point of the wedge-shaped opening 1031. The scale position of the oil level adjustment scale mark corresponding to the support plate 109 is the target adjustment scale position, that is, the support plate 109 is equivalent to a pointer, and the scale position corresponding to the support plate 109 is the target adjustment scale position. In this embodiment, the scale position corresponding to the highest point of the wedge-shaped opening 1031 is not defined as the target adjustment scale position because the position corresponding to the highest point of the wedge-shaped opening 1031 and the oil level adjustment scale mark is not easy to read and is prone to reading errors. Therefore, the support plate 109 is selected as the indicating component to avoid adjustment errors caused by misreading.

[0065] The outer wall of the oil cup base 104 is provided with an oil level scale mark. The oil level indicated by the scale position that is the same as the target adjustment scale position is the design standard oil level. When the oil level in the equipment to be lubricated is lower than the design standard oil level, the adjustable constant-level oil cup adds oil to the equipment to be lubricated.

[0066] In this embodiment, an oil level scale mark is creatively provided on the outer wall of the oil cup base 104, and there is a corresponding relationship between the oil level scale mark and the oil level in the lubricated equipment. For example, when it is desired to adjust the oil level in the lubricated equipment to the height of the oil level a marked on the oil level scale mark through external observation, it is only necessary to adjust the support plate 109 to the oil level a marked on the oil level adjustment scale mark.

[0067] It should be noted that the oil level a indicated by the oil level adjustment scale on the adjustment rod is not at the same height as the oil level a indicated by the oil level adjustment scale on the oil cup base 104. When the support plate 109 is adjusted to the oil level a indicated by the oil level adjustment scale, the height of the highest point of the wedge-shaped opening 1031 is at the height of the oil level a indicated by the oil level adjustment scale on the oil cup base 104. This requires that when setting the oil level adjustment scale and the oil level scale, the scale position on the oil level adjustment scale needs to be lower than the same scale position on the oil level scale by a certain distance, and this distance is the height of the wedge-shaped opening 1031 along the axial direction of the lower branch pipe 103.

[0068] In this embodiment, by setting the oil level adjustment scale mark and the oil level scale mark, the oil level scale mark can be used to observe the desired adjusted oil level height, and then the support plate 109 can be adjusted to the scale position corresponding to the same oil level height to adjust the height of the highest point of the wedge-shaped mouth 1031 to the desired adjusted height position, and then the desired design standard oil level can be successfully adjusted at one time.

[0069] For easier observation, the oil level scale mark can be set as a zero oil level mark, and the height position of the zero oil level mark is the position corresponding to the highest point of the lumen of the horizontal branch pipe 108. The scale above the zero oil level mark can be marked in sequence according to positive numbers, and correspondingly, the scale below the zero oil level mark can be marked in sequence according to negative numbers.

[0070] The oil level adjustment scale mark has a zero oil level adjustment mark, and the height position of the zero oil level adjustment mark is the position corresponding to the highest point of the lumen of the transverse branch pipe 108. The scale above the zero oil level adjustment mark can be marked in sequence according to positive numbers, and correspondingly, the scale below the zero oil level adjustment mark can be marked in sequence according to negative numbers.

[0071] Since the position of the horizontal branch pipe 108 is the position of the oil filling port on the equipment to be lubricated, this position is specially set according to the lubrication conditions. Therefore, its position is close to the design standard oil level. In this embodiment, a zero oil level mark and a zero oil level adjustment mark are added to facilitate the operator to judge the oil level height to be adjusted, and how much higher or lower it is than the highest point of the tube cavity of the horizontal branch pipe 108.

[0072] In a specific embodiment of the utility model, an oil cup outer sleeve 102 is provided at the lower part of the oil cup body 101. The oil cup outer sleeve 102 is sleeved on the outer side of the lower branch pipe 103, and the lower branch pipe 103 extends outward from the outer side of the oil cup outer sleeve 102. The oil cup outer sleeve 102 is sleeved on the outer side of the oil cup base 104, and a ventilation gap is formed between the oil cup outer sleeve 102 and the oil cup base 104.

[0073] As the lubricating oil in the equipment to be lubricated is consumed, the oil level in the equipment to be lubricated drops to below the highest point of the wedge-shaped opening 1031 of the lower branch pipe 103. External air can enter the oil cup base 104 through the ventilation gap between the oil cup outer sleeve 102 and the oil cup base 104, and then enter the oil cup body 101 through the wedge-shaped opening 1031, so that the pressure in the oil cup body 101 is equal to the external atmospheric pressure. The lubricating oil in the oil cup body 101 will flow into the equipment to be lubricated under the action of gravity, so that the oil level in the equipment to be lubricated continues to rise to the designed standard oil level. The highest point of the wedge-shaped opening 1031 is sealed by the oil level, thereby ensuring that the oil level in the lubricating equipment always remains at the designed standard oil level.

[0074] The oil cup outer sleeve 102 is sleeved on the outside of the oil cup base 104, and there is a ventilation gap between the two; those skilled in the art can understand that, the larger the width of the ventilation gap, the easier it is for the oil cup outer sleeve 102 to be sleeved on the oil cup base 104 during installation, that is, the easier it is to complete the installation of the oil cup body 101, but the larger the width of the ventilation gap, the more unstable the oil cup body 101 will be after installation, causing the oil cup body 101 to shake.

[0075] In order to overcome the above contradiction, in this embodiment, at least one of the inner wall of the oil cup outer sleeve 102 and the outer wall of the oil cup base 104 is provided with a positioning convex strip, and when the oil cup outer sleeve 102 is sleeved on the oil cup base 104, the positioning convex strip is located between the inner wall of the oil cup outer sleeve 102 and the outer wall of the oil cup base 104. A plurality of positioning convex strips can be evenly provided, and the portion between the positioning convex strips can realize the entry of air.

[0076] When the positioning convex strip is set on the oil cup outer sleeve 102, the thickness of the positioning convex strip on the oil cup outer sleeve 102 gradually increases from bottom to top. In this way, the thickness of the lower end of the positioning convex strip on the oil cup outer sleeve 102 can be thinner, making it easier to complete the sleeve connection between the oil cup outer sleeve 102 and the oil cup base 104. As the oil cup outer sleeve 102 moves downward, the thicker part of the positioning convex strip on the oil cup outer sleeve 102 will gradually be inserted between the oil cup outer sleeve 102 and the oil cup base 104, so that the distance between the positioning convex strip and the outer wall of the oil cup base 104 is small, thereby improving the stability of the oil cup body 101 after installation.

[0077] When the positioning convex strip is set on the oil cup base 104, the thickness of the positioning convex strip on the oil cup base 104 gradually increases from top to bottom. In this way, the thickness of the upper end of the positioning convex strip on the oil cup base 104 can be thinner, making it easier to complete the sleeve connection between the oil cup outer sleeve 102 and the oil cup base 104. As the oil cup outer sleeve 102 moves downward, the thicker part of the positioning convex strip on the oil cup base 104 will gradually be inserted between the oil cup outer sleeve 102 and the oil cup base 104, so that the distance between the positioning convex strip and the inner wall of the oil cup outer sleeve 102 is small, thereby improving the stability of the oil cup body 101 after installation.
