[0002] In the field of mechanical transmission, gear assemblies are core transmission components, and their lubrication directly affects the operating accuracy, transmission efficiency, and service life of equipment. To reduce frictional losses during gear meshing, lower noise, and prevent component corrosion, it is usually necessary to apply grease to key areas such as the tooth surfaces and shaft holes of the gear assembly.

[0003] Currently, the application of grease to gear assemblies is difficult to ensure even distribution of grease on the gear surface, which can easily lead to localized grease buildup or missed areas, thus affecting the assembly quality and performance of the gear assemblies. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a gear assembly grease leveling device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gear assembly grease leveling device includes: an operating table, on the upper surface of which is provided a positioning platform, a positioning groove, a bearing notch and a circumferential positioning groove on the upper peripheral wall of the positioning groove, a first bearing support surface at the bottom of the bearing notch, the bearing notch penetrating the peripheral wall of the positioning groove, and a second bearing surface at the bottom of the circumferential positioning groove; both the circumferential positioning groove and the bearing notch are used for inserting protrusions protruding from the peripheral wall of the gear assembly; and a rotary motor mounted on the operating table, with a rotating shaft extending into the positioning groove at its upper end, a slot on the upper surface of the rotating shaft for inserting a central shaft extending from the bottom of the gear assembly to achieve synchronous rotation of the rotating shaft and the central shaft.

[0007] Furthermore, the operating table is provided with an installation cavity, the bottom of the positioning slot is provided with a communication hole communicating with the installation cavity, the rotary motor is fixedly installed in the installation cavity, and the rotating shaft passes through the communication hole and extends into the positioning slot.

[0008] Furthermore, the upper edges of the positioning groove, the bearing notch, and the circumferential positioning groove are chamfered.

[0009] Furthermore, a circumferential positioning plate is provided within the bearing notch, and the circumferential positioning plate has a positioning opening groove with an upper opening for the corresponding protrusion to be inserted.

[0010] Furthermore, the upper end of the opening of the positioning slot is flared.

[0011] Furthermore, an installation plate is provided on the outer side of the bearing notch, and a pre-tightening block is elastically and movably installed on the installation plate, the pre-tightening block being used to contact the protrusion.

[0012] Furthermore, the mounting plate is provided with a through hole, and the pretensioning block is provided with a movable post that is movably inserted through the through hole.

[0036] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a gear assembly grease leveling device, which includes an operating table 100 and a rotary motor 200.

[0037] The upper surface of the operating table 100 is provided with a positioning platform 110, and the positioning platform 110 is provided with a positioning groove 120. The upper peripheral wall of the positioning groove 120 is provided with a bearing notch 130 and a circumferential positioning groove 140. The bearing notch 130 and the circumferential positioning groove 140 are circumferentially spaced apart. The bottom of the bearing notch 130 is provided with a first bearing support surface 131. The bearing notch 130 penetrates the peripheral wall of the positioning groove 120. The bottom of the circumferential positioning groove 140 is provided with a second bearing surface 141. Both the circumferential positioning groove 140 and the bearing notch 130 are used for the protrusions 102 protruding from the peripheral wall of the gear assembly 101 to be embedded. In this embodiment, the peripheral wall of the gear assembly 101 has three protrusions 102, one bearing notch 130, and two circumferential positioning grooves 140.

[0038] A rotary motor 200 is mounted on the operating table 100. The upper end of the rotary motor 200 has a rotating shaft 210 that extends into a positioning groove 120. The upper surface of the rotating shaft 210 has a slot 220 for inserting a central shaft 103 extending from the bottom of the gear assembly 101, thereby achieving synchronous rotation between the rotating shaft 210 and the central shaft 103. The slot 220 is a spline groove, and the portion of the central shaft 103 protruding from the gear assembly 101 at its lower end has matching spline teeth, thus achieving torque transmission.

[0039] This utility model provides a gear assembly grease leveling device. The positioning groove 120 on the positioning platform 110 provides basic positioning for the gear assembly 101. The bearing notch 130 and circumferential positioning groove 140 on the upper peripheral wall of the positioning groove 120 can adapt to the protruding portion 102 on the peripheral wall of the gear assembly 101, forming a circumferential limit. This ensures that when the gear inside the gear assembly 101 rotates, the outer shell of the gear assembly 101 does not rotate. The first bearing support surface 131 at the bottom of the bearing notch 130 and the second bearing surface 141 at the bottom of the circumferential positioning groove 140 can provide multi-point stable support for the protruding portion 102. This prevents the weight of the gear assembly 101 from being concentrated on the rotating shaft 210 of the rotary motor 200, distributing the weight of the gear assembly 101 to the positioning platform 110. This effectively reduces the load on the rotating shaft 210 of the rotary motor 200, lowers the risk of wear and deformation, and extends the equipment's lifespan. The bearing notch 130 penetrates the peripheral wall of the positioning groove 120, facilitating the operator's access to the gear assembly 101 and providing ample operating space for handling the gear assembly 101, thus improving operational convenience. The upper end face of the rotating shaft 210 of the rotary motor 200 has a slot 220 that precisely engages with the central shaft 103 extending from the bottom of the gear assembly 101, achieving synchronous rotation between the rotating shaft 210 and the central shaft 103. This ensures that the grease is evenly distributed along with the stable rotation of the gears. Simultaneously, it allows for testing to check for abnormal noises or jamming during gear rotation inside the gear assembly 101.

[0040] Reference Figure 4 In some embodiments of this utility model, the operating table 100 is provided with a mounting cavity 150, and the bottom of the positioning groove 120 is provided with a communicating hole 160 communicating with the mounting cavity 150. The rotary motor 200 is fixedly mounted in the mounting cavity 150, and the rotating shaft 210 extends into the positioning groove 120 through the communicating hole 160. The mounting cavity 150 in the operating table 100 provides an independent mounting space for the rotary motor 200, effectively isolating it from external dust corrosion and reducing the outward transmission of noise during motor operation. The communicating hole 160 at the bottom of the positioning groove 120 provides a channel for the rotating shaft 210 to pass through the positioning groove 120.

[0041] Reference Figure 3 In some embodiments of this utility model, the upper edges of the positioning groove 120, the bearing notch 130, and the circumferential positioning groove 140 are chamfered. By setting the chamfer, the ease of installation of the gear assembly 101 is improved. The chamfer structure can guide the gear assembly 101 to be quickly aligned and inserted, avoiding bumps and jamming during installation, reducing component wear, and at the same time reducing the difficulty of operation for operators and improving installation efficiency.

[0042] Reference Figures 5 to 7In some embodiments of this utility model, a circumferential positioning plate 170 is provided within the bearing notch 130. The circumferential positioning plate 170 has a positioning opening groove 171 with an upper opening for the corresponding protrusion 102 to be inserted. It is understood that when placing the gear assembly 101, it may be necessary to slightly rotate the gear assembly 101 to align the central shaft 103 and insert it into the slot 220. Therefore, the width of the bearing notch 130 and the circumferential positioning groove 140 is usually slightly larger than that of the protrusion 102, so that the protrusion 102 has a certain range of rotational movement to allow the gear assembly 101 to be initially placed and rotated and adjusted until the central shaft 103 is aligned and inserted into the slot 220. The circumferential positioning plate 170 and its positioning opening groove 171 further optimize the circumferential positioning accuracy of the gear assembly 101, so that after installation, the outer shell of the gear assembly 101 cannot rotate, only the gear set inside can rotate, thereby avoiding the outer shell from shaking or bumping due to rotation.

[0043] Reference Figures 5 to 7 In a further embodiment of this utility model, the upper end of the opening of the positioning slot 171 is flared. Flaring the upper end of the opening of the positioning slot 171 forms a guide flared structure. This allows for easier guidance of the protrusion 102 into the positioning slot 171 during gear assembly 101 installation, and provides the gear assembly 101 with a range of rotation when in the upper position of the positioning slot 171. This allows for position adjustment until the central shaft 103 is aligned and inserted into the slot 220. When the gear assembly 101 is fully lowered, the protrusion 102 slides into the bottom position of the positioning slot 171, and the width of the bottom of the positioning slot 171 matches the protrusion 102, thereby achieving circumferential fixation of the gear assembly 101.

[0044] Reference Figures 5 to 7 In a further embodiment of this utility model, a mounting plate 180 is provided on the outer side of the bearing notch 130, and a preload block 300 is elastically and movably mounted on the mounting plate 180. The preload block 300 is used to contact the protrusion 102. The preload block 300 can apply a continuous and moderate preload force to the protrusion 102 embedded in the bearing notch 130, ensuring that the housing of the gear assembly 101 remains stably positioned during rotation, except for loosening caused by gaps.

[0045] Reference Figures 5 to 7 In a further embodiment of this utility model, the mounting plate 180 is provided with a through hole 181, and the pretensioning block 300 is provided with a movable post 310 that movably passes through the through hole 181. A compression spring 320 is sleeved on the movable post 310, and the compression spring 320 is located between the pretensioning block 300 and the mounting plate 180. The movable post 310 passes through the through hole 181 of the mounting plate 180 to form a sliding guide, and the movable post 310 also provides a stable mounting position for the compression spring 320. The compression spring 320 provides a stable elastic pretensioning force for the pretensioning block 300.

[0046] Reference Figures 5 to 7 In a further embodiment of this utility model, the end of the movable column 310 facing away from the preload block 300 passes through the through hole 181 and is provided with a threaded column 330, on which a nut 340 is threadedly connected. By adjusting the position of the nut 340 on the threaded column 330, the compression amount of the compression spring 320 can be changed, thereby adjusting the magnitude of the preload force of the preload block 300 on the protrusion 102. Furthermore, the profile of the nut 340 is larger than that of the through hole 181, which can also prevent the movable column 310 from disengaging from the through hole and also achieve the initial positioning of the movable column 310.

[0047] Reference Figures 5 to 7 In a further embodiment of this utility model, the upper end of the preload block 300 on the side facing away from the movable column 310 is provided with a transition chamfer 350. By providing the transition chamfer 350 on the upper end of the preload block 300 on the side facing away from the movable column 310, during the installation of the gear assembly 101, the protrusion 102 can smoothly push the preload block 300 outward along the transition chamfer 350, reducing resistance and collisions during installation and making the installation process smoother and less strenuous. It can be understood that when the nut 340 abuts against the mounting plate 180, the preload block 300 reaches its furthest inward extension position. At this time, when the gear assembly 101 is placed, the protrusion 102 descends and contacts the transition chamfer 350, pushing the preload block 300 outward as it descends.

[0048] Reference Figures 5 to 7 In a further embodiment of this utility model, the pretension block 300 is provided with two movable columns 310, which can improve the movement stability of the pretension block 300. The double movable column structure can prevent the pretension block 300 from tilting or rotating during elastic expansion and contraction.

[0049] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
