Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cycling machine load device, and more particularly, to a cycling machine load device that has an effect of improving the noise problem of the cycling machine and extending the service life of the cycling machine.

[0002]

[Prior art]

 The structure of a permanent magnet load device of a known cycling machine is generally as shown in FIG. 1, which usually comprises a flywheel 20 erected on a support seat 10, one side of the flywheel 20. A transmission means 30 (for example, a multi-groove pulley) is fixed to the support sheet, and both the flywheel 20 and the transmission means 30 are coaxially pivoted on the same shaft rod 40, and the support sheet is further utilized by using the shaft rod 40. It is erected at 10. A small number of permanent magnets 201 and a coiled stator silicon steel piece 202 are provided equidistantly on the ring surface of the flywheel 20, whereby the flywheel 20 is rotated by the transmission of the transmission means 30. When the flywheel 20 rotates, an induced electric force is generated by the relative rotation between the permanent magnet 201 and the stator silicon steel piece 202, and the amount of current is controlled according to the speed change when the flywheel 20 rotates. The torque is controlled to create resistance when rowing the cycling machine and achieve a health-promoting effect that puts a load on exercise.

However, when a cycling machine was actually used, it was found that a known cycling machine often generates vibration and noise when stepping on it.

[0004] As a result of a deep study of the structure of the prior art, it was found that the above-mentioned problem of the prior art lies in the flywheel 20 of the load device. To smoothly rotate the flywheel 20 and the transmission means 30 on the shaft 40, it is necessary to install two sets of bearings 50 between the transmission means 30 and the shaft 40, as shown in FIG. In order to position the bearing 50, a known cycling machine uses a C-shaped snap ring 501 to lock the outside of the bearing 50. However, the C-shaped snap ring 501 has an error of 0.1 to 0.2 mm at the time of manufacturing and production. A play is formed so that when the transmission means 30 and the flywheel 20 rotate, the bearing 50 slides left and right on the shaft 40 and collides with the C-shaped snap ring 501 and other articles and reduces friction. The vibrations and noise of the cycling machine are thus formed. This collision situation causes breakage of the C-shaped snap ring 501 in a mild case, and affects the life of the bearing 50 in a heavy case. In addition, in the known structure, the outer diameter of the shaft 40 used is only 15 mm, and there is another problem that the loading force of the shaft 40 is insufficient.

【Example】

 As shown in FIG. 2, the load device of the present invention includes a flywheel 2 provided on a support sheet 1, and the flywheel 2 is directly mounted on the outside of a transmission means 3 (for example, a multi-groove pulley). Further, both the flywheel 2 and the transmission means 3 are coaxially pivoted on the same shaft 4, and are bridged on the support sheet 1 using the shaft 4. The outer diameter of the shaft rod 4 of the present invention is 17 to 25 mm, and is inserted into the transmission means 3 and a stop seat 6 is first installed between the two, and as shown in FIG. An annular receiving surface 61 is formed on the seat 6, and a first bearing 5, a spacer ring 7 and a second bearing 5 ′ that are combined with the diameter of the inner annular surface of the transmission means 3 are provided on one side of the annular receiving surface 61. The outside of the second bearing 5 'is formed as an annular seal piece 8 which is screwed to the inner ring surface of the transmission means 3 and directly presses the second bearing 5'.

With the above arrangement, the annular seal piece 8 is screwed onto the inner annular surface of the transmission means 3 and directly presses the outer surface of the second bearing 5 ′, thus exerting an axial thrust on the second bearing 5 ′. Is generated, and the second bearing 5 ′ is pressed against the spacer ring 7, and the spacer ring 7 and the first bearing 5 are pressed against the stop seat 6 so as to come into contact with each other. The seal member 8, the second bearing 5 ', the spacer ring 7, the first bearing 5, and the stop seat 6 form a tight contact and no gap as shown in FIGS. In this way, when the transmission means 3 drives and rotates the flywheel 2, the first and second bearings 5, 5 'have no gap on both sides and there is no phenomenon of left and right movement. It does not cause vibration and noise and prolongs the service life of the cycling machine. By selecting a shaft 4 with a relatively large outer diameter, the loading capacity of the shaft 4 is greatly increased. can do.
