Description

Technical Field

[0001] The utility model relates to the technical field of planetary carriers, and more specifically, to a planetary carrier with a lubricating function. Background Art

[0002] The planet carrier is used to install the planetary gear shaft and is one of the main components of the planetary gear transmission. Its structural design and manufacturing have a great impact on the load distribution between the planetary gears and the load-bearing capacity, noise and vibration of the transmission device. The planet carrier is usually equipped with oil ports to improve the lubrication effect between the planetary gear sets.

[0003] The Chinese invention patent with application number 202311609391.2 discloses a planetary carrier, a wind turbine gearbox and an oil supply method for a wind turbine gearbox, in which injection ports are provided on the inner and outer rings of the planetary carrier. The external oil supply system can continuously spray oil and lubricate the sun gear and the outer gear ring through the injection ports, thereby improving the lubrication effect. However, the planetary carrier is always in a rotating state during the operation of the planetary gear structure. The structure required for oil supply to the injection ports in the planetary carrier is relatively complex, which increases the overall volume of the planetary gear device. In addition, oil leakage or even detachment of the interface may occur during high-speed rotation, affecting the use of the device. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a planetary carrier with a lubrication function.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model is further configured as follows: the oil storage bag is made of elastic material.

[0008] The utility model is further configured as follows: a plurality of slide grooves are provided on the rear side plate and the front side plate, each of the two sides of the cavity is symmetrically connected with a slide groove, a pressure plate is slidably connected to the side of the cavity away from the one-way valve, the pressure plate cover is pressed on the oil storage bag, and slide grooves are extended from both sides of the pressure plate and are respectively connected with a float.

[0009] The utility model is further configured as follows: the one-way valve includes a connecting pipe, an end of the inner wall of the connecting pipe away from the oil storage bag is configured as a frustum opening, a spring is installed in the connecting pipe, the free end of the spring faces the side away from the oil storage bag, the free end of the spring is connected to a plug, and the plug is normally sealed and connected to the frustum opening of the connecting pipe.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0020] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually used in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually used in reference to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0021] See also Figure 1-4 , the utility model provides the following technical solutions:

[0022] A planetary carrier with lubrication function comprises a rear side plate 1 and a front side plate 2, support columns 3 are evenly spaced and connected between the rear side plate 1 and the front side plate 2, a plurality of support columns 3 are staggered with a plurality of preset planetary gears, a cavity 31 is provided in the support column 3, an oil storage bag 4 is installed in the cavity 31, the oil storage bag 4 is made of elastic material, a one-way valve 5 is installed between the outer wall of the oil storage bag 4 and the support column 3, the flow direction of the liquid at the one-way valve 5 is toward the oil storage bag 4, a plurality of injection pipes 9 are connected to the oil storage bag 4, the nozzles of the plurality of injection pipes 9 are respectively directed to the inner side and the outer side of the rear side plate 1, a plurality of slide grooves 32 are provided on the rear side plate 1 and the front side plate 2, each of the two sides of the cavity 31 is symmetrically connected with a slide groove 32, a pressure plate 6 is slidably connected to the side of the cavity 31 away from the one-way valve 5, the pressure plate 6 covers the oil storage bag 4, the slide grooves 32 are extended on both sides of the pressure plate 6, and a floating ball 7 is connected respectively;

[0023] When the support column 3 rotates to the oil pool, the floating balls 7 on both sides drive the pressure plate 6 to float upward under the action of buoyancy to overcome the centrifugal force, that is, the floating balls 7 drive the pressure plate 6 to move to one side of the axis, the top of the oil storage bag 4 is released, the oil storage bag 4 is restored, and the oil in the oil pool opens the one-way valve 5 and enters the oil storage bag 4, thereby replenishing the oil in the oil storage bag 4;

[0024] After the support column 3 continues to rotate out of the oil pool, the floats 7 on both sides lose buoyancy, and the floats 7 and the pressure plate 6 are thrown to the outside of the support column 3 under the action of centrifugal force, thereby squeezing the oil storage bag 4. The oil in the oil storage bag 4 is squeezed through the injection pipe 9 and continuously sprayed onto the sun gear and the outer ring gear, thereby improving the lubrication effect.

[0025] A plurality of oil outlet pipes 8 are provided in the outer wall of the support column 3, and the oil outlet pipes 8 are connected with the oil storage bag 4. The injection pipes 9 are provided on the rear side plate 1 and the front side plate 2, and the injection pipes 9 are correspondingly connected with the oil outlet pipes 8. The diameters of the oil outlet pipes 8 and the injection pipes 9 are smaller than the flow diameter of the one-way valve 5. The large-diameter one-way valve 5 is convenient for quickly replenishing the oil when the oil storage bag 4 is in the oil pool, and the small-diameter injection pipe 9 prolongs the continuous injection time of the oil and the time for replenishing lubrication. At the same time, when the oil storage bag 4 is restored, it is easier to replenish the oil through the large-diameter one-way valve 5 rather than inhaling gas through the small-diameter injection pipe 9, thereby ensuring the efficiency of oil replenishment.

[0026] The one-way valve 5 includes a connecting tube 51, and the end of the inner tube wall of the connecting tube 51 away from the oil storage bag 4 is set as a frustum opening. A spring 53 is installed in the connecting tube 51, and the free end of the spring 53 faces the side away from the oil storage bag 4. The free end of the spring 53 is connected to a plug 52, and the plug 52 is normally sealed and connected to the frustum opening of the connecting tube 51.

[0027] Specifically, an oil storage bag 4 is installed in each support column 3, and oil is supplied to the oil storage bag 4 through a one-way valve 5. A pressure plate 6 is pressed on the inner side of the oil storage bag 4, and both ends of the pressure plate 6 are connected to floats 7. When the support column 3 rotates to the oil pool, the float 7 overcomes the centrifugal force and moves toward the axis side under the action of buoyancy. When the oil storage bag 4 is restored, the one-way valve 5 opens to absorb oil inward. After the support column 3 is rotated out of the oil pool, the float 7 and the pressure plate 6 are thrown outward under the action of centrifugal force, and the pressure plate 5 squeezes the oil storage bag 4. The oil in the oil storage bag 4 is continuously sprayed onto the sun gear and the outer ring gear through the injection pipe 9, thereby improving the lubrication effect without the need for an external system and simplifying the overall structure.
