[0049] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.
[0050] The invention provides a needle bushing, such as Figure 5 to Figure 14 As shown, it includes multiple needle rollers 1 and two end retaining rings (2, 3); multiple needle rollers 1 are movably installed between the two end retaining rings.
[0051] The needle roller 1 includes a cylindrical needle roller body and hemispheres at both ends of the cylindrical needle roller body; the cylindrical needle roller body has a high cylindricity, which can basically reach the accuracy of the ball in the bearing; the two ends of the needle roller are hemispheres The body is used to reduce the friction with the end retaining ring; there is a...
