Abstract

A roller structure and a manufacturing method thereof are introduced. The roller structure includes a roller rotatable about an axial portion; a bush with an end disposed to an end of the axial portion and has a first stop portion positioned proximate to one side of the roller and another end having an engaging portion coupled to a load; and a second stop portion disposed to the other end of the axial portion and positioned proximate to the other side of the roller such that the roller rotates between the first stop portion and the second stop portion. Hence, the roller structure and the manufacturing method thereof provide a modularized roller structure for carrying a load, effectuate modularized assembly and production, enhance assembly efficiency, attain structural streamlining, and cut costs.

First claim

What is claimed is:

1 . A roller structure, comprising:
a roller rotatable about an axial portion, an end of a bush is disposed to an end of the axial portion, and another end of the bush having an engaging portion coupled to a load; and a second stop portion disposed at another end of the axial portion and positioned proximate to a side of the roller such that the roller rotates between the second stop portion and the engaging portion.

2 . The roller structure of claim 1 , wherein the bush has a first stop portion positioned proximate to another side of the roller.

3 . The roller structure of claim 1 , wherein the bush is formed integrally with or coupled to the axial portion.

4 . The roller structure of claim 3 , wherein the second stop portion is formed integrally with or coupled to the axial portion.

5 . The roller structure of claim 1 , wherein the second stop portion is formed by injection molding.

6 . The roller structure of claim 1 , wherein the second stop portion is in form of a stop component fitted around the axial portion, and the axial portion has a third stop portion for limiting movement of the stop component.

7 . The roller structure of claim 1 , further comprising a connection component coupled to the axial portion, wherein the second stop portion is in form of a stop component whose movement is limited by the connection component.

8 . The roller structure of claim 7 , wherein a receiving chamber concentric with the axial portion is disposed on one or two sides of the roller and adapted to receive one of the first stop portion, the second stop portion and the third stop portion.

9 . The roller structure of claim 7 , wherein the stop component is in form of a hollow-core component penetrable by the connection component.

10 . The roller structure of claim 1 , wherein a limiting portion is disposed on a side of the roller such that the second stop portion is confined to between the limiting portion and the roller.

11 . The roller structure of claim 1 , wherein the roller comprises one of an inner ring, a rolling component and a sliding component for fitting around the axial portion.

12 . The roller structure of claim 1 , wherein the second stop portion penetrates the axial portion, or the second stop portion penetrates the axial portion and the bush, or the axial portion penetrates the second stop portion.

13 . The roller structure of claim 12 , wherein the second stop portion penetrates the axial portion and is coupled to the axial portion by a riveting mechanism, an expansion mechanism, a welding mechanism, an engaging mechanism, a fastening mechanism, an adhesion mechanism or a magnetic attraction mechanism, or the second stop portion penetrates the axial portion and the bush and is coupled to the bush by a riveting mechanism, an expansion mechanism, a welding mechanism, an engaging mechanism, a fastening mechanism, an adhesion mechanism or a magnetic attraction mechanism.

14 . The roller structure of claim 1 , wherein the engaging portion of the bush is positioned proximate to a side of the load such that the bush and the load are coupled together by a connection component.

15 . The roller structure of claim 1 , further comprising a frame which the engaging portion of the bush and the load are coupled to.

16 . The roller structure of claim 1 , wherein the roller and the axial portion are coupled to the bush and the second stop portion to form a module and then the engaging portion of the bush is coupled to the load.

17 . The roller structure of claim 1 , wherein the roller and the axial portion are coupled to the second stop portion to form a module so as for the bush to be coupled to the load to form a module and eventually for the axial portion to be coupled to the bush.

18 . The roller structure of claim 1 , wherein the engaging portion of the bush has a feeding space which a material of the load is injected into via a die such that the engaging portion is coupled to the load; or the engaging portion of the bush is transformed via a die to have a feeding space, the feeding space receives a material of the load to couple the engaging portion to the load.

19 . The roller structure of claim 1 , wherein a diameter of the engaging portion is larger or smaller than a diameter of the roller.

20 . The roller structure of claim 18 , wherein the feeding space faces the roller or faces away from the roller.

21 . The roller structure of claim 1 , wherein the engaging portion coupled to the load via pressing the second stop portion, pressing the roller or pressing the engaging portion.

22 . The roller structure of claim 2 , wherein the engaging portion coupled to the load via pressing the second stop portion, pressing the roller, pressing the engaging portion or pressing the first stop portion.

23 . The roller structure of claim 15 , wherein the engaging portion coupled to the frame via pressing the second stop portion, pressing the roller or pressing the engaging portion.

24 . A manufacturing method of the roller structure of claim 1 , comprising the step of forming the second stop portion positioned proximate to a side of the roller by using a die in performing a pressing process on a pressed portion at another end of the axial portion.
