Embodiment 1
[0040] Such as figure 1 As shown, a flexible bearing assembly method based on the full-ball design, while heating the inner and outer rings of the non-full-ball flexible bearing, put the non-full-ball 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. until the outside of the upper end of the outer ring is close to the lower end of the "herringbone" 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" mold 11 vertically from top to bottom, so that the The non-full-ball flexible bearing produces elastic deformation. At this time, the inner and outer rings at the left and right upper ends of the non-full-ball flexible bearing are opened, and steel balls are filled in here until the ball is full, ...
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 a full-ball design, which is characterized in that while heating the inner and outer rings of the non-full-ball flexible bearing, horizontally put the non-full-ball flexible bearing into the upper part The "herringbone" shape that can move up and down, and the lower part is in the middle of the fixed cylindrical mold, until the upper end of the outer ring is close to the lower end of the "herringbone" mold, and the upper end of the inner ring is close to the upper end of the cylindrical mold, continue from Squeeze the "herringbone"-shaped mold upwards and downwards to cause elastic deformation of the non-full ball flexible bearing. Steel ball until full ball, complete the assembly process of the bearing.
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...
