Abstract: A belt-driven generator essentially comprises a stator and a rotor. The rotor exteriorly includes a driving annular surface. With the driving annular surface, the rotor can be directly connected to the belt and driven by the drive unit, thus reducing vibration and noise while extending the service life of the generator. In addition, the part cost, the assembly cost and the assembly space of the generator can be reduced.

Abstract: A bicycle generator mounting structure comprises: a base, an adjusting member, a connecting member, and a flexible member. The adjusting member is disposed on and adjustable in position with respect to the base mounted on a bicycle frame. The connecting member is disposed on the adjusting member. The generator is connected to the connecting member via the flexible member which is capable of returning to its original shape after deformation, hence, the flexible member can absorb the noise caused when the bicycle is running and keep the generator in optimal contact with the wheel.

Abstract: A shock-absorbing device for an exercycle dynamo comprises a bracket and a dynamo. The dynamo generates electricity for the exercycle, and the bracket is connected to the dynamo and the exercycle by plural elastic members, which can provide different shock-absorbing and buffering effects on different positions of the bracket. By such arrangements, better shock-absorbing and buffering effect can be provided to the dynamo.

Abstract: A power supply arrangement for body fitness machine is disclosed to include permanent magnets mounted on the flywheel of the body fitness machine, a rack mounted on the base frame of the body fitness machine to hold a stack of silicon steel plates, and windings mounted on the rack to act with the permanent magnets for inducing electric current for the working of the lighting circuit of the instrument panel of the body fitness machine.

Abstract: A pneumatic lubricating system for use in an exercising machine is disclosed to include an oil tank with an oil inlet, an air inlet and an oil outlet, an oil filling pipe connected to the oil inlet for the filling of a lubricating oil into the oil tank, an one-way valve installed in the oil inlet for letting an oil lubricating oil be filled into the oil tank, an air pipe connected to the air inlet, an oil distribution tube with nozzle holes for output of a lubricating oil, an oil pipe connected between the oil outlet and the oil distribution tube, and an air pump for pumping air through the air pipe into the oil tank via the air inlet to force storage lubricating oil out of the oil outlet into the oil distribution tube via the pipe for application.

Abstract: A power-supplying and shock-absorbing device for an exerciser consists of a bracket and a dynamo. The dynamo generates electricity for the exerciser, and the bracket is connected with the dynamo and the exerciser by plural elastic members, which can provide different shock-absorbing and buffering effects on different positions of the bracket. By such arrangements, better shock-absorbing and buffering effect can be provided to the dynamo.
