Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a planetary carrier for mining trucks. Background Technology

[0002] In the production processes of modern large-scale coal mines, mines, steel mills, and ports, mining trucks play an increasingly important role and have become the main force in production. Mining trucks need to be equipped with a combined planetary carrier, which is one of the main components of the planetary gear transmission device. The planetary gear shafts or bearings are mounted on the planetary carrier. When the planetary gear is used as a basic component, it is the part that bears the largest external torque in the mechanism, and its main function is to reduce speed.

[0003] A search revealed application CN202322763179.3, entitled "A Mining Truck Planetary Carrier for Easy Assembly." This application addresses the problem that existing planetary carrier covers are mostly fixed by welding or bolts. When maintenance of the inner side of the planetary carrier is required, disassembling and assembling the limiting cover on the planetary carrier is inconvenient, affecting later maintenance efficiency. Furthermore, assembly requires tools, making operation cumbersome and resulting in poor performance. The application solves this problem by using a combination of springs, mounting grooves, limiting grooves, locking rods, and locking slots to facilitate the removal and assembly of the limiting cover, thus avoiding the problem of inconvenient disassembly and assembly leading to poor maintenance and replacement of planetary gears. The device is also simple to operate, has a stable connection, and is easy to install. This invention significantly improves maintenance efficiency and enhances the effectiveness of the device. Furthermore, the coordinated use of the delivery pipe, oil injection pipe, and other structures allows for lubrication of the planetary gear connections within the planetary carrier, extending the lifespan of the planetary gears. Operation can be completed without disassembling the cover plate. However, in actual use, the relatively fixed position of the oil injection pipe and the fixed oil injection location prevent even coverage of the planetary gear structure, resulting in reduced lubrication uniformity and coverage, affecting the comprehensiveness and efficiency of lubrication. Additionally, its limiting structure is complex, requiring operators to operate levers to unlock it, making it cumbersome to use. Further improvements are possible.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a planetary carrier for a mining truck according to an embodiment of the present invention includes a housing 1 and a cover plate 5.

Multiple sets of pinion 9 are arranged in a planetary configuration, which is a common structure in the art. A distributor pipe 3 is connected through the surface of the main shaft tube 2 above the sun gear 8, and an oil injector 4 is connected through the surface of the distributor pipe 3. An oil inlet pipe 15 is rotatably connected through the bottom surface of the main shaft tube 2 via a hydraulic rotary connector 14, and a drive gear 13 is fixedly sleeved on the surface of the main shaft tube 2 below the housing 1. An outlet pipe 15 is connected through the bottom surface of the housing 1. The oil pipe 16 is fixedly installed on the top surface of the housing 1, and a positioning post 7 is fixedly installed on the top surface of the magnetic ring 6. The top surface of the cover plate 5 is provided with a positioning hole 17 corresponding to the positioning post 7. The drive gear 13 meshes with the gear mechanism at the output end of the drive motor. The oil inlet pipe 15 is connected to the output end of the lubricating oil circulation pump. The oil outlet pipe 16 is connected to the input end of the lubricating oil circulation pump through a filter. The main shaft tube 2 drives the sun gear 8 to rotate, drives the pinion 9 to rotate, drives the gear ring 10 to rotate, drives the housing 1 and the cover plate 5 to rotate. The main shaft tube 2 drives the distributor pipe 3 to rotate, drives the oil injector 4 to rotate. The lubricating oil enters the main shaft tube 2 through the hydraulic rotary connector 14 and is sprayed out through the rotating oil injector 4, which sprays the sun gear 8, pinion 9 and gear ring 10 evenly, improving the uniformity of the lubricating oil spray, improving the lubrication efficiency, and thus improving the working efficiency.

[0028] In one embodiment, the spindle tube 2 is rotatably connected to the bottom surface of the housing 1 via a sealed bearing, and the spindle tube 2 is made of seamless steel pipe, with a wall thickness of not less than one-third of the radius of the spindle tube 2. The structural strength of the spindle tube 2 meets the usage requirements and avoids damage under stress.

[0029] In one embodiment, a rotating ring 12 is fixedly installed on the bottom surface of the housing 1, and a ring seat 11 is rotatably sleeved on the outer side of the rotating ring 12. The ring seat 11 is fixedly installed on the surface of the mining truck mounting frame, and the rotating ring 12 rotates inside the ring seat 11 to stabilize the rotation of the housing 1 and the cover plate 5.

[0030] In one embodiment, multiple sets of split pipes 3 are arranged, and the split pipes 3 are distributed at equal angles along the central axis of the main shaft pipe 2. Multiple sets of oil injectors 4 are arranged, and the oil outlet direction of the oil injectors 4 is directly facing the sun gear 8, pinion 9 and gear ring 10, thereby improving the lubricating oil spraying efficiency.

[0031] In one embodiment, multiple sets of positioning posts 7 and positioning holes 17 are arranged, and the height of the positioning posts 7 is less than the depth of the positioning holes 17 to prevent the positioning posts 7 from protruding from the positioning holes 17. The cover plate 5 is made of stainless steel, which facilitates magnetic fixation with the magnetic ring 6. The magnetic ring 6 is magnetically fixed to the cover plate 5 to prevent the cover plate 5 from moving up and down at will. The positioning posts 7 are inserted into the positioning holes 17 to prevent the cover plate 5 from sliding relative to the housing 1 when the housing 1 rotates, thereby improving the stability of rotation. The operator only needs to move the cover plate 5 up and down to install and remove the cover plate 5, making the installation more convenient and simple, and further improving the ease of use.

[0032] In one embodiment, the cover plate 5 has a through hole at its center for the spindle tube 2 to pass through, which is a common structure in the art and will not be described in detail here.

The oil inlet pipe 15 is connected to the output end of the lubricating oil circulation pump, and the oil outlet pipe 16 is connected to the input end of the lubricating oil circulation pump through a filter. The main shaft tube 2 drives the sun gear 8 to rotate, which in turn drives the pinion 9 to rotate, drives the gear ring 10 to rotate, and drives the housing 1 and cover plate 5 to rotate. The main shaft tube 2 drives the distributor pipe 3 to rotate, which in turn drives the oil injector 4 to rotate.

At the same time, the magnetic ring 6 is magnetically fixed to the cover plate 5 by magnetic force, preventing the cover plate 5 from moving up and down at will. The positioning pin 7 is inserted into the positioning hole 17 to prevent the cover plate 5 from sliding relative to the housing 1 when the housing 1 rotates, thus improving the stability of rotation. The operator only needs to move the cover plate 5 up and down to install and remove the cover plate 5, making the installation more convenient and simple, and further improving the ease of use.
