Description
[technical field]
The utility model is the twin axle high-ratio gear about a kind of body-building apparatus.
[background technology]
In present various body building training device or the device, the device of its traction and transmission, its structure is mostly according to the characteristic of body building, and design various different structural form, and the complexity of its structure is also different with the purposes of training device, if during a multiduty mechanism, transmission device and whole volume be very huge mostly, and floor space must have the place of certain space to hold following, if not therefore in the family broadness of ten minutes be enough to hold, otherwise must be in specific health institution or club, therefore the user must drive to move to this specific place, not only time and effort consuming when using, and, increase the burden of user's consumer cost, and, the design of its transmission device, mostly be with single counter weight device, become the place of Excercise training apparatus traction drag, and the counterweight of this counter weight device keeps certain, it can't be different with the variation of stroke, be difficult to meet the variation in the athletic performance, so necessity of improvement is arranged.
And have the people all to design at simple function at the body-building apparatus institute development product of miniaturization, so the also simplification thereupon of its relative transmission device, but still must keep certain resistance or drag, for user's pulling motion; Therefore the installing inertia wheel disc in transmission device that has, forming an inertia strength, and very limited of this inertia strength, DeGrain, therefore there is the people to add the structure of magnetic resistance or other dampings again, but also very limited of resistance structure effect so, wherein, twine the form that the flying wheel friction produces resistance with ribbon, its ribbon is tightened inertial flywheel, and provides elastic damping with spring, so structure, following defective is arranged, such as:
1, damped elasticity can't keep certain: its elastic damping is the unitary elasticity damping function, and the strength of its spring can be loose gradually with the time of using, and the strength of damping just diminishes thereupon, loses the strength of damping gradually, so necessity of improvement is arranged.
2, damping distortion: the formation of its damping is to tighten ribbon with spring to reach, and it provides a frictional force, and promptly as brake, sensuously not nature very is different fully with the impression of actual motion for this frictional force, so be difficult to meet the demand in the motion.
Because very limited of the body-building equipment structure of miniaturization, the effect of its damping is difficult to meet consumer demand in fact; And the preferable general medium-and-large-sized exercycle of damping performance, its structure is comparatively complicated, the cost height, with the pedal body building vehicle is example, for the effect that makes damping more meets real sensation, on exercycle, use large-scale damping unit so that the process that exercycle is stepped on has more due inertia sense mostly, the exercycle that has also has the structure of magnetic resistance form, and this magnetoresistive structures not only makes integrally-built complexity increase, and volume heightens, and, still mostly only can provide the function of single foot-operated body-building, so necessity of improvement is arranged.
