Abstract
The utility model discloses a heald frame with roll balls. The heald frame comprises an upper cross beam and a lower cross beam, wherein left sheets and right sheets are fixedly connected with the left and right ends of the upper cross beam and the lower cross beam; a plurality of groups of roll ball bodies are inlaid in the upper cross beam and the lower cross beam; each group of roll ball bodies comprises two rows of roll balls, an upper support and a lower support; the roll balls are arranged between the upper support and the lower support. A roll ball vibration isolation system is adopted by the heald frame; as the roll ball bodies are inlaid in the cross beams of the heald frame, the energy dissipation is generated by virtue of rolling frictional resistance effect between each roll ball and the upper and lower support, vibration energy of a certain heald frame, transferred to an adjacent heald frame, is reduced so as to achieve the effect of vibration isolation between the adjacent heald frames; meanwhile, since the roll balls are higher than the surface of the cross beam, when the adjacent heald frames collide, the roll balls are in collision with the cross beams of the adjacent heald frame, the bending of the cross beams of the heald frame can be greatly reduced and the service life of the heald frame is prolonged.
