[0003] As shown in Figures 2 and 3, the production of the above-mentioned front roller 2 and rear roller 3 is to use the two ends of the roller to assemble the bearing 5, and then use the bearing 5 to assemble the bearing 6. The traditional bearing is generally a single Made of iron, the processing cost and materials are quite expensive
[0004] In addition, the bearing sleeve 5 processed by the solid round bar has the disadvantages of high cost and long processing time, and the processed bearing sleeve 5 is assembled on the roller 2, and there is also a problem of falling off due to force

Embodiment Construction

[0015] The invention provides a method and a structure for avoiding bearing sleeves for the front and rear rollers of an electric treadmill.

[0016] Such as Figure 4 Shown, this figure is the flowchart of manufacturing method of the present invention, and this manufacturing method comprises:

[0017] 1) Take the roller pipe material of the iron pipe 30 first, and use the super hardness mold 40 (shrinking mold) to shrink the ports 31 at both ends of the iron pipe 30;

[0018] 2) Extrude the preformed shape of the retaining edge, and then punch and extrude the inner concave bearing assembly space 32, and form the bearing retaining edge 33 at the same time;

[0019] 3) The processing machine finishes turning the bearing assembly space 32, and then assembles the bearing in the bearing assembly space 32, and the bearing is stopped and limited by the bearing edge 33.

[0020] Through the above steps, the bearing assembly of the bearing-free roller set is completed.

[0021] The ...

Abstract

The invention discloses a method and a structure of the front and back rollers of an electric runner that do not use paylean cases, particularly relating that the front and back positions of the running belt of a runner combination are provided with rollers. The combination paylean position of the two ends of the rollers need to go through pipe contraction and punching to be directly squeezed to form paylean combination space, and the paylean can be combined directly after machinery finishing in order to achieve the purposes that the cost is saved, the structure is simple, the material density is tighter after squeezing and does not fall off.

Description

technical field [0001] The invention relates to an electric treadmill, in particular to a method and a structure for the front and rear rollers of the electric treadmill without bearing sleeves. Background technique [0002] As shown in Fig. 1, the commonly known treadmill mainly comprises a treadmill 1, a front roller 2 is pivotally arranged at the front end of the treadmill 1, a rear roller 3 is pivotally arranged at the rear end, and the front and rear rollers 2 and 3 are provided with There is a running belt 4, so that the front roller 2 can drive the running belt 4 to rotate. [0003] As shown in Figures 2 and 3, the production of the above-mentioned front roller 2 and rear roller 3 is to use the two ends of the roller to assemble the bearing 5, and then use the bearing 5 to assemble the bearing 6. The traditional bearing is generally a single Made of iron, the processing cost and materials are quite expensive. [0004] In addition, the bearing sleeve 5 processed by t...
