Treadmill resistance adjustment structure

This creative department is part of a treadmill creation, especially for the improvement of the adjustment structure of the belt tension of the treadmill motor and belt drive.

Press, when the treadmill uses the motor to drive the running belt to rotate, most of the belt and the pulley are used as the medium for transmitting power. At the same time, a pressure wheel is added next to the belt to hold the belt, mainly because the size of each pulley is different during transmission. However, the pulley has a different rotation speed, and the pulley having a smaller diameter has a higher rotation speed. In addition, the smaller pulley has a smaller contact area between the outer circumferential surface and the belt, and the frictional force is less likely to cause the belt to be fixed on the outer circumferential surface thereof. The belt is easily slipped off, causing the pulley to idle, resulting in waste of power during the transfer process.

In addition, when the treadmill's running board is angled to the climbing type, in order to increase the resistance of the user's climbing, in addition to increasing the resistance by increasing the belt tension of the belt drive, it can also be assisted by the motor. However, the use of pressure rollers for increasing the tension of the belt is inconvenient, the effect is limited, and the structure is complicated and not practical. The use of the motor power supply to increase the resistance of the running belt will adversely affect the motor for a long time, and is improved. Necessary.

In addition, as shown in the sixth figure, in order to reduce the rotation ratio of the motor to drive the running belt, there is a conventional creation of a medium wheel (244) between the motor (245) and the running belt before the drum (240), the medium wheel ( 244) having a larger first tread (2440) and a smaller second tread (2442), and further providing a first belt (246) between the first tread (2440) and the motor (245), A second belt (247) is disposed between the second tread (2442) and the front drum (240). Although this kind of custom creation can achieve the purpose of reducing the speed ratio However, the method of adjusting the tension of the belt can not be used to increase the resistance when the treadmill is used in the climbing state, and it is necessary to improve it.

In view of this, the creator has in-depth discussion on the above-mentioned practical creation issues, and actively seeks solutions through years of experience in R&D and manufacturing of related industries.
