This invention provides a planetary gear reducer, belonging to the technical field of reducer technology. It solves the problem of unstable torque in existing technologies. This invention includes a front housing, a gear ring body, a rear housing, a planetary gear assembly, an input shaft, and an output splined shaft. The front housing, gear ring body, and rear housing are connected sequentially, and the planetary gear assembly is installed inside the front housing, gear ring body, and rear housing. The planetary gear assembly includes planetary gears, a sun gear, and a planet carrier. The planet carrier is a hollow annular sleeve with a mounting hole in the center and a connecting ring formed on the rear side. The planetary gears are fitted onto the planetary shafts and located in the mounting hole, meshing with the inner side of the gear ring body. The sun gear is located inside the planet carrier and meshes with the planetary gears. A keyway groove is formed on the inner side of the connecting ring groove on the rear side of the planet carrier, and the output splined shaft is connected to the rear side of the planet carrier through the keyway groove. This invention has the advantages of stable torque transmission and high precision.

By rotating upper jar body to let out operating space, avoid the inconvenience in traditional structure, clean dirt in jar body or overhaul structure in jar body through manhole;Height adjustment assembly flexible adaptation upper jar body and lower jar body structure dislocation, without the aid of external lifting equipment, it is convenient to rotate upper jar body, realize the purpose of quickly opening upper jar body.

This utility model discloses a rotating tray structure for a dining table, relating to the technical field of dining tables. It includes a rotating tray and a base. The rotating tray is movably fastened to the base, forming a mounting cavity. A rotating gear ring is provided within the mounting cavity. The inner side of the rotating gear ring has annular meshing teeth. A driving component is provided on the inner side of the rotating gear ring. The driving component engages with the annular meshing teeth for transmission. The rotating gear ring can drive the rotating tray to rotate. An upper anti-slip ring is provided between the rotating tray and the rotating gear ring, and a lower anti-slip ring is provided between the rotating tray and the base. Several movable rolling balls are fitted into both the upper and lower anti-slip rings. This utility model's rotating tray structure not only solves the inconvenience of manual rotation but also achieves efficient and stable rotation control through electrification, while maintaining a simple and modern style, meeting users' high requirements for aesthetics, stability, and convenience.

This invention relates to a measuring device and method for measuring the out-of-roundness of boiler pressure vessel cylinders, comprising a telescopic frame and a ranging device. The ends of the first, second, and third telescopic sections are extendable, so that the extension axes of the second and third telescopic sections coincide with the chord length of the boiler pressure vessel, which is equal in length and parallel to the chord length. This, in turn, causes the rotation axis of the ranging device to coincide with the axis of the boiler pressure vessel. The advantages are that by determining the center and then rotating to measure the full circumference diameter, the measurement results are highly accurate. Simultaneously, the rotational measurement method allows for rapid measurement in a short time, thus improving measurement efficiency. Since the telescopic frame can internally clamp the boiler pressure vessel, it has excellent adaptability to boiler pressure vessels with different inner diameters, thereby greatly improving the flexibility of the measuring device for the out-of-roundness of boiler pressure vessel cylinders.

The application relates to the technical field of lithium battery processing devices, and discloses a waste lithium battery recycling device for new energy vehicles, which comprises a crusher. The application uses a special-shaped feeding box as a waste lithium battery feeding channel; an adjusting handle is rotationally connected to the inner wall of a supporting shaft I; rotating the adjusting handle can drive the threaded rod at the bottom of the adjusting handle to rotate synchronously; one end of the threaded rod, which is away from the adjusting handle, is supported and limited by a supporting shaft II. Since the outer wall of the threaded rod is in threaded connection with a feeding adjusting plate, the threaded rod can drive the two feeding adjusting plates to move up and down when the threaded rod rotates; a limiting sliding block is slidably connected in two limiting sliding grooves symmetrically arranged on the surface of the feeding adjusting plate; the left side of the limiting sliding block is fixedly connected with a feeding limiting plate; and the feeding limiting plate is slidably connected to the inner walls of two guide sliding grooves symmetrically arranged on the crusher. When the feeding adjusting plate moves up and down, the feeding limiting plate is driven by the limiting sliding block to slide obliquely along the guide sliding groove, so that the distance between the two symmetrically-arranged feeding limiting plates is adjusted.

This invention provides a method for processing a tapered roller bearing cage. Step one: The sheet metal is cut, stretched, punched with window holes, edge-machined on the large end face, and then the bottom is cut to form a cage blank. Step two: The window beam is beveled to create a guide slope that contacts the rolling elements. The guide slope of the cage meets a first surface roughness requirement, while the remaining non-working surfaces of the cage only need to meet a second surface roughness requirement, which is higher than the first. Step three: A protective component is placed over the window holes of the cage blank, with the coverage area of ​​the protective component being larger than the beveled surface after finishing. Step four: The covered cage blank undergoes two shot blasting treatments. If the surface quality of the cage does not meet the requirements, the surface treatment process parameters need to be adjusted for a third shot blasting treatment. This method solves the problems of low efficiency and high cost associated with the existing all-around finishing process for bearing cages.
