The synchronous lower end is provided with a synchronous tooth 101, the synchronous tooth 101 is meshed with a power gear of external power equipment, the synchronous belt 1 is driven to rotate through the power gear, and synchronous transmission is realized through the meshing of the synchronous tooth 101 and the gear. The side edge of the synchronous belt 1 is connected with a large strip, and the thickness of the conducting strip 2 is larger than that of the synchronous belt 1. The lower end face of the conducting bar 2 is not provided with the synchronous teeth 101, the conducting bar 2 is attached to guide wheels on external equipment such as a running machine, a plurality of guide wheels can be arranged along the length direction of the conducting bar 2, and the limiting and supporting effects are achieved through the cooperation of the conducting bar 2 and the guide wheels. The leading wheel can support the drive belt, can understand, among the treadmill work engineering, synchronous drive belt need bear the weight of sportsman, sets up leading wheel cooperation conducting bar 2 and plays the supporting role, guarantees the stationarity when the drive belt moves, reduces the tight power that rises that the drive belt received simultaneously and the noise in the motion process. The guide wheel is matched with the guide bar 2 to play a limiting role, so that the transmission belt moves along the length direction, derailment of the transmission belt is avoided, abrasion of the synchronous teeth 101 and the transmission gear on the synchronous belt 1 is reduced, and the service life of the transmission belt is prolonged.
Example 2
Referring to fig. 2, in this embodiment, on the basis of embodiment 1, the outer surfaces of the synchronous belt 1 and the guide bar 2 are covered with a reinforcing layer 4.
In this embodiment, the reinforcing layer 4 is made of rubber, and is used for increasing the connection strength of the driving belt, avoiding the safety accident caused by the breakage of the driving belt, and improving the safety of the synchronous belt 1.
Further, in some implementations of the present embodiment, a plurality of reinforcing cores 5 are disposed inside the reinforcing layer 4, and the reinforcing cores 5 are disposed in parallel.
The reinforced core 5 and the reinforced layer 4 are injection molded, and the reinforced rib can be made of high-strength polyester ropes and is arranged in the reinforced layer 4; the reinforcing core body 5 can reduce the extrusion of the outside, can also increase the strength of the transmission belt and prolong the service life.
Further, in some embodiments of the present embodiment, the timing belt 1 and the guide bar 2 are integrally formed.
The integral forming process is mainly used in the manufacturing industry, namely, a certain part is manufactured by one-time processing, secondary and more processing is not needed, and the manufacturing of the certain part is completed by one procedure in the whole process. The integrated forming and the non-integrated forming are two different manufacturing processes, and the manufactured product or part is an integral body without any connection, so that the quality is higher and the use is longer compared with the non-integrated forming.

The fixing holes 6 on the synchronous belt 1 are matched with the connecting studs to firmly fix the pedals on the transmission belt, so that safety accidents caused by slipping of the pedals are avoided. It can be understood that when a person moves rapidly on the running machine, the pedal falls off suddenly, which easily causes the person to throw out backwards, and causes great damage to the person.
Example 4
Referring to fig. 3, in this embodiment, on the basis of some of the above embodiments, the surfaces of the synchronous belt 1 and the guide bar 2 are covered with a wear-resistant layer 7.
The wear-resistant layer 7 is filled with wear-resistant mesh cloth, so that the friction resistance of the wear-resistant layer 7 is improved, and the wear resistance of the synchronous belt 1 and the guide bars 2 is improved. It will be appreciated that in this embodiment, during the movement of the timing belt, the timing teeth 101 and the guide bars 2 need to contact with the transmission gear and the guide wheel, and friction is inevitably generated during the contact process, so that the timing teeth 101 or the guide bars 2 are worn. The wear-resistant layer 7 is arranged to increase the strength of the synchronous teeth 101 and the guide bars 2, and further to increase the service life of the synchronous drive belt. The wear-resistant mesh cloth is formed by interweaving a plurality of longitudinal warps and a plurality of transverse wefts, and is integrated with the wear-resistant layer 7 in an injection molding mode. The wear-resistant mesh can increase the strength of the transmission belt, and even if the synchronous belt 1 or the guide bar 2 is broken, the wear-resistant mesh can play a role in connection, so that the whole transmission belt is prevented from being broken suddenly and completely, and the safety of the transmission belt is ensured.
Alternatively, in some implementations of this embodiment, the synchronizing teeth 101 are in a trapezoidal structure.
In the above embodiment, the synchronizing teeth 101 have a trapezoidal structure, and the side of the synchronizing teeth 101 contacting the synchronous belt 1 is wider and the side thereof distant from the synchronous belt 1 is narrower. The trapezoidal structured synchronizing teeth 101 are more easily engaged with the external gear to provide kinetic energy. In order to realize continuous transmission, the synchronous belt 1 and the guide bar 2 are connected end to form an annular transmission belt, and two ends of the annular transmission belt form an arc-shaped structure. The trapezoidal synchronous teeth 101 are matched with an arc-shaped transmission belt when in motion, so that the meshing degree of the synchronous teeth 101 and an external gear is improved, and the transmission effect is improved. It can be understood that the existing transmission gear is usually in a disc-shaped structure, and the synchronous teeth 101 with large upper part and small lower part are arranged to better engage with the transmission gear, so that the stability during transmission is improved, and the shake and noise are reduced.
