Abstract
The utility model discloses an installation structure for an exercise cycle one-way flywheel. The installation structure comprises a connecting shaft. The flywheel is installed on the connecting shaft through a bearing A. A ratchet wheel is arranged between the flywheel and the connecting shaft. One side of the flywheel on the connecting shaft is provided with a belt wheel fixedly connected with the flywheel and installed on the connecting shaft through a bearing B. The flywheel on the connecting shaft and the outer side of the belt wheel are connected with a nut. A plastic shaft sleeve is further arranged between the flywheel and the nut. The bearing A and the ratchet wheel together support the flywheel, so structure is firm and service life of the bearing A and the ratchet wheel are respectively prolonged. In addition, the plastic shaft sleeve is arranged between the outer side of the flywheel and the nut, so noise caused by friction is lowered.
Description
Technical field
The utility model belongs to body-building apparatus component technology field, is specifically related to the unidirectional flywheel mounting structure of a kind of body-building vehicle.
Background technology
The unidirectional flywheel that is used for body-building vehicle of prior art generally is connected to ratchet between flywheel and the drive pulley, and not compactness of inconvenience and structure is installed.
Summary of the invention
The purpose of this utility model is: the deficiency for prior art exists provides a kind of compact conformation, the unidirectional flywheel mounting structure of body-building vehicle easy for installation.
For realizing the purpose of the utility model, be achieved by the following technical solutions: the unidirectional flywheel mounting structure of a kind of body-building vehicle, include adapter shaft, flywheel is installed on the adapter shaft by bearing A, and be provided with ratchet between flywheel and the adapter shaft, a side of flywheel is provided with the belt wheel of captiveing joint with flywheel on the adapter shaft, and belt wheel is installed on the adapter shaft by bearing B; The outside of flywheel and belt wheel is connected with nut on the described adapter shaft, also is provided with plastic sleeve between flywheel and the nut.
As preferred version: also be connected with the decorative pattern nut on the described adapter shaft.
Compared with prior art, the beneficial effects of the utility model are: owing to flywheel is installed on the adapter shaft by bearing A, and between flywheel and the adapter shaft ratchet is set, like this, the common support flying wheel of bearing A and ratchet, sound construction all obtains prolonging the service life of bearing A and ratchet; In addition, be provided with plastic sleeve between the flywheel outside and the nut, reduced fricative noise.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1, flywheel; 2, bearing A; 3, plastic sleeve; 4, nut; 5, belt wheel; 6, bearing B; 7, decorative pattern nut; 8, ratchet; 9, adapter shaft.
The specific embodiment
The below makes a detailed explanation the specific embodiment of the present utility model with reference to the accompanying drawings.
According to shown in Figure 1, the unidirectional flywheel mounting structure of the described a kind of body-building vehicle of present embodiment, include adapter shaft 9, flywheel 1 is installed on the adapter shaft 9 by bearing A2, and be provided with ratchet 8 between flywheel 1 and the adapter shaft 9, a side of flywheel 1 is provided with the belt wheel 5 of captiveing joint with flywheel 1 on the adapter shaft 9, and belt wheel 5 is installed on the adapter shaft 9 by bearing B6; The outside of flywheel 1 and belt wheel 5 is connected with nut 4 on the described adapter shaft 9, also is provided with plastic sleeve 3 between flywheel 1 and the nut 4.
Also be connected with decorative pattern nut 7 on the described adapter shaft 9.
Described flywheel 1 is installed on the adapter shaft 9 by two bearing A2, ratchet 8 between two bearing A2, bearing A2 and ratchet 8 common support flying wheels 1, sound construction all obtains prolonging the service life of bearing A2 and ratchet 8.
Plastic sleeve 3 is when flywheel 1 counter-rotating, and namely flywheel 1 has avoided nut and bearing A2 directly to produce friction and generation noise when adapter shaft 9 rotates.
