Specific embodiment
To describe technical scheme by the following examples in detail, below example is only exemplary, only
Can be used for explaining and illustrate technical scheme, and be not to be construed as the restriction to technical solution of the present invention.
The application provide one kind can bearing torque straight-line guidance assembly, as shown in Fig. 2 include the axis of guide 4, keeper 2, lining
Set 3 and needle roller 1.
The axis of guide 4 be polygon prism structure, in the present embodiment, the axis of guide be equilateral quadrangular structure, the application its
In its embodiment, the axis of guide can also be equilateral triangular prism, equilateral pentagonal prism or equilateral six prism structures；In order to prevent the axis of guide
Edges and corners be excessively sharp and two neighboring plane is unable to gentle transition, or even produce the problem of stress concentration, logical in the application
Cross the edges and corners to the axis of guide and do chamfered, in this application, you can also rounding to lead right angle.
The both ends of the axis of guide are cylindrical structural, to ensure the twisting action of the axis of guide.
