Embodiment 1

[0040] Such as figure 1 As shown, a flexible bearing assembly method based on a full-ball design, while heating the inner and outer rings of a non-full-ball flexible bearing of a common design, put the flexible bearing horizontally into the upper part to form a "person" that can move up and down. ” font 1, the lower part is in the middle of a fixed cylindrical 2 mold, and an electromagnetic heating device 4 is arranged around the mold 2. The outside of the upper end of the outer ring is close to the lower end of the "herringbone"-shaped mold 1, and the inner side of the upper end of the inner ring is close to the upper end of the cylindrical mold 2. Continue to squeeze the "herringbone"-shaped mold 11 vertically from top to bottom, so that the The flexible bearing produces elastic deformation. At this time, the inner and outer rings at the left and right upper ends of the flexible bearing are opened, and steel balls are filled in here until they are full, completing the assemb...

Embodiment 2

[0044] Compared with Example 1 in Example 2, the N is 27-30.

[0045] The utility model relates to a flexible bearing based on a full-ball design, and the bearing is applied to a flexible bearing cam type wave generator of a harmonic reducer.

Abstract

The invention relates to a flexible bearing assembly method based on full-ball design. The flexible bearing assembly method based on the full-ball design is characterized in that when an inner ring and an outer ring of a commonly designed non-full-ball flexible bearing is heated, a flexible bearing is horizontally placed between an upper herringbone mould which can move up and down and a lower fixed cylindrical mould until the outer side of the upper end of the outer ring is tightly attached to the lower end of the herringbone mould and the inner side of the upper end of the inner ring is tightly attached to the upper end of the cylindrical mould, the herringbone mould continues to be extruded from top to bottom to enable the flexible bearing to generate elastic deformation, at the moment, the inner ring and the outer ring, at the upper left end and the upper right end, of the flexible bearing are open, steel balls are filled in the open position one after the other until the position is full, and the bearing assembly process is completed.

Description

technical field [0001] The invention relates to a flexible bearing based on a full-ball design, its application and an assembly method. Background technique [0002] Harmonic gear transmission technology was produced with the development of space science and aerospace cutting-edge technology in the late 1950s. Harmonic transmission is a device that uses elastic deformation waves of flexible components for motion or power transmission. Its advantages are: 1, simple structure, 2, large transmission ratio, wide range of transmission ratio, 3, high load capacity, stable transmission, high precision and low noise, 4, small backlash of transmission, can realize zero backlash transmission, 5 , high transmission efficiency. It has been widely used in space technology, radar communication, energy, machine tools, instrumentation, robots, automobiles, shipbuilding, textiles, metallurgy, conventional weapons, precision optical equipment, printing and packaging machinery, and medical eq...
