According to the inertia flywheel speed control system of the fitness recovery equipment, a spindle which inputs moment of force drives an insert flywheel rotating around the spindle in manner of connection by a gear transmission mechanism. The inertia flywheel speed control system of the fitness recovery equipment mainly solves the technical problems that the existing inertia flywheel speed change system of the exercise bike has complex structure and takes up large space, and the drive belt is easy to skid, run away and fall off; the inertia flywheel speed control system can increase the labor efficiency during production and manufacturing, reduces the production cost and lowers the reject ratio of the product; simultaneously, the system has compact structure and takes up small space.
Description
Technical field
The utility model relates to speed change gear, particularly a kind of exercise rehabilitation equipment inertial flywheel speed variator system.
Background technique
The structure of the inertial flywheel speed variator system of traditional exercycle sees also Fig. 1.As shown in the figure: it comprises the inertial flywheel 108 that vehicle frame 101 that the inertial flywheel speed variator system is installed, the crank 102, big belt pulley 103, belt 104 and the small belt pulley that transmit extraneous torsion moment connect as one; The idler mechanism that comprises idle pulley 105, lever plate 106, spring 107 in addition in addition.When body-building or rehabilitation clients move; The sporter at first drives crank 102 rotations, and big belt plate wheel 103 rotates around crankshaft with unequal angular velocity because of being fixed on the crank 102, drives belt 104, inertial flywheel 108 like this and moves together; Because big belt pulley 103 is several times of diameters of small belt pulley (small belt pulley and inertial flywheel 108 are one); The angular velocity of rotation of inertial flywheel 108 is several times of crank 102 equally, and the rotating speed of inertial flywheel 108 is high more, and the effect of exercise or rehabilitation is just good more.Because the diameter difference of big small belt pulley, belt transmit the efficient of torsion will be not good enough, for high transmission efficiency is arranged; The idle pulley structure is just arranged in the speed variator system; Increase the wrap angle of small belt pulley, reduce belt slippage, thereby make body building person reach the purpose of body-building or rehabilitation preferably.
Yet,, the manufacturing and use are had a lot of inconvenience and trouble for for the big small belt pulley of use, belt, many wheel mechanisms exercise rehabilitation equipment.This inertial flywheel speed variator system has following drawback: the one, and mostly vehicle frame is to be welded when making; And the form and position tolerance of big small belt pulley need guarantee, will guarantee when welding and assembling that like this accuracy of manufacturing just needs to increase technological equipment, and check and correction repeatedly; Thereby increase labor intensity influences manufacturing efficiency.The 2nd, big small belt pulley adds idler mechanism, adds vehicle frame etc., is meeting under the situation of security regulations during design, is difficult to arrange their positions each other that the occupation space position is bigger through regular meeting; The 3rd, the speed changing structure of belt pulley, belt composition, belt adjustment tension ruptures easily when dispatching from the factory, and reduces working life; Belt was adjusted pine and can be skidded; Big small belt pulley position no adjustment alignment can produce race band even belt dropping; Add sporter's individual difference, make after sales service work quantitative change big; Particularly when gear ratio is big, can increase the requirement of idler mechanism, it is more complicated that the structure of idler mechanism also can become.
The model utility content
The purpose of the utility model is to provide a kind of exercise rehabilitation equipment inertial flywheel speed variator system; Mainly solve existing exercycle inertial flywheel speed variator system complex structure, take up room big; And the technical problem that drive belt skidded, ran band easily, comes off; The efficiency that it can improve the manufacturing has reduced cost of production, reduces the product reject ratio; Simultaneously this system architecture compact, occupy little space.
For realizing above-mentioned purpose, the utility model is to realize like this.
A kind of exercise rehabilitation equipment inertial flywheel speed variator system is characterized in that: it is to be connected through gear shift by the main shaft of input torque to drive an inertial flywheel around main axis rotation.
Described exercise rehabilitation equipment inertial flywheel speed variator system; It is characterized in that: the concrete composition structure of this system is; It comprises the main shaft of two ends connecting crank; Be arranged with bearing support and bearing on the fixing vehicle frame respectively with inboard, two crank joints on this main shaft; Bearing inboard on the main shaft is arranged with the central gear that includes little bearing, the then fixedly sleeved planetary carrier in another bearing inboard on the main shaft, this planetary carrier and with the internal gear that is fixed on the vehicle frame also is set between the side shaft holder; Through a connection planetary pinion, the sheathed inertial flywheel of this central gear outer fixing is then meshed with internal gear engagement, inboard in this planetary pinion outside with central gear in this planetary carrier.
Described exercise rehabilitation equipment inertial flywheel speed variator system is characterized in that: described planetary carrier and planetary pinion are to be linked together by three little axles, and little axle is fixed on the planetary carrier, and planetary pinion is installed on the little axle by planetary gear bearing.
Use the utility model device advantage compared with prior art to be.
The utility model system is made up of one group of epicyclic transmission, and the same main shaft of gear, inertial flywheel connect and constitute the inertial flywheel speed variator system, and the velocity ratio size of system is confirmed by intermeshing gear set specifications at different levels.Entire mechanism is around main axis rotation, and is installed in the inboard of inertial flywheel.This system has the characteristics such as easily manufactured, that the transmission speed ratio scope is big, transmission speed ratio is stablized, the position that takes up room is little of installing.
