Abstract

The present invention relates to a magnetic tension control weight training machine containing a base, large revolver wheel, belt disc, shaft set, bearing assembly, pulley assembly, magnetic resistance flywheel, pulling rope and a reposition device. A wheel spacer is welded to the center of the large revolver wheel within which there is a bearing assembly, on one side fixed with a small revolver wheel for reposition. The shaft set fits through the bearing assembly, one end welded with a shaft disc to fasten the belt disc that is connected with the magnetic resistance flywheel and the large revolver wheel by means of the belt. The size of the small revolver wheel and the active pulley makes the extension length of the flexible components quite short. The reposition device adjusts the reposition course through the active pulley and the adjustment bolt, allowing for the control of the force.

Claims

1. A magnetic tension control training machine comprising:

a base;

a large revolver wheel;

a belt disc;

a shaft set;

bearing assembly;

pulley assembly;

a magnetic resistance flywheel;

a first pulling rope; and

a reposition device, wherein said base has first and second braces, said large revolver wheel is connected to said first brace, and said magnetic resistance flywheel is connected to said second brace, said magnetic resistance flywheel is connected to said belt disc by a belt, said large revolver wheel is connected to said belt disc and drives said magnetic resistance flywheel, said belt disc, said bearing assembly, said shaft set and said pulley assembly are located on the first brace said pulley assembly for said first pulling rope is located above said large revolver wheel, the bearing assembly having a one-way bearing and two second bearings are located in a wheel spacer of said large revolver wheel, the shaft set is inserted through the wheel spacer and the bearing assembly, a shaft disc of the shaft set is connected to the belt disc, and a small revolver wheel is connected to said large revolver wheel, said reposition device is located on first and second flex fixtures and connected to said small revolver wheel, the first flex fixture has an adjustment bolt connected to a bracket and the second flex fixture has a plurality of flexible components connected to an active pulley, said bracket is connected to a first end of a second pulling rope, said second pulling rope extending through said active pulley and around a carriage pulley, and a second end of said second pulling rope is connected to said small revolver wheel;

when said first pulling rope is extended said large revolver wheel is rotated and said one-way bearing inside said large revolver wheel makes said small revolver wheel pull on said second pulling rope and extend the plurality of flexible components, when the first pulling rope is retracted, the plurality of flexible components pull on said second pulling rope to return said large revolver wheel back to an original position.

2. The magnetic tension control weight training machine of claim 1, wherein said shaft set has a snap ring to position said bearing assembly.

3. The magnetic tension control weight training machine of claim 1, further comprising two flanged housings, each of the two flanged housings connecting one of two opposing ends of said shaft set to said first brace.

4. The magnetic tension control weight training machine of claim 1, wherein said two second bearings are metallic bushings.
