Abstract
The utility model provides a brand new motorized treadmill with a motor arranged in a roller and operating in a unique mode. The motorized treadmill comprises either an alternating current motor or a direct current motor, and is characterized in that a traditional external motor is arranged in a front roller of the motorized treadmill, the front roller of the treadmill is a supporting roller connected with a running belt as well as a motor rotor, an original axis becomes a motor stator incapable of rotating and also becomes a motor wire connection hidden hole, fixed rotation directions of the motor stator and the motor rotor of a traditional motorized treadmill are completely changed, and steel materials and copper materials are greatly saved. Functions of the motor and functions of a rolling shaft are combined, a multi-groove belt and multi-groove belt wheels are omitted, production cost is reduced, and installation space is emptied; material-saving and energy-saving effects are remarkable, installation and debugging are convenient to carry out, noise and vibration of the motor and the multi-groove belt of the roller during connection and transmission are eliminated, and the motorized treadmill with the motor arranged in the roller is an innovation in the field of motorized treadmills at home and abroad.
Description
Technical field
The utility model provides a kind of treadmill of cylinder built-in motor, belongs to body-building apparatus technical field.
Background technology
Existing treadmill employed both at home and abroad is all to adopt motor by polywedge bet, transmits polywedge bet power is delivered to blanket roller, and front-wheel roller drives treadmill belt to move, shortcoming is to use parts many, middle off-energy, and cost cost is high, take up room large, installation and debugging are loaded down with trivial details.
Utility model content
The object of this patent is to provide a kind of treadmill that can overcome above-mentioned shortcoming, reduce manufacturing cost, energy-conservation cylinder built-in motor.Its technical scheme is:
Comprise motor, back roll and treadmill belt, it is characterized in that: change original rotor, stator direction, inserts motor in cylinder, and the rotor of motor is front roll, and axle core is the stator of motor, and power supply lead wire is drawn by the dark hole of axle core.
The rotor exterior ring shape of described motor is coated with sound absorption shell, described sound absorption shell is cavity structure, on the outer surface of cavity structure, have multiple gaps or through hole, gap or through hole connect flexible hose, the degree of depth that the length of flexible hose is greater than cavity structure is placed in cavity structure in the shape of a spiral, one end that flexible hose is connected with gap or through hole is openend, and the other end is blind end, is freely placed in cavity structure.At outer surface coating one deck sound-absorbing material of cavity structure.
The surface of cavity structure can be also hard material of soft material, the preferably perforated plate of hard, and perforated plate has the hard plate in through hole or gap.The cavity structure of sealing has through hole or gap and flexible hose is set, and triplicity is got up, and further increases acoustic absorptivity and acoustic resistance, widens its sound sucting band simultaneously.Tube bank rearranges with the flexible hose of through hole or gap diameter identical elongated by some, the length of flexible tube bank is not subject to the dark restriction in cavity structure chamber (can be designed to different in size, with the acoustic absorptivity under resonance tuning frequency and change different frequency, reach modulation and widen the object of sound sucting band), it is dark that the length of each root flexible hose can be less than chamber, also can be greater than chamber dark.Because elongated pipe is arranged in enclosed cavity and embeds the surface of cavity structure, thereby increase acoustic absorptivity, in enhancing, effective absorption of low-frequency noise, improve high frequency acoustically effective simultaneously, widen sound sucting band.
The treadmill of described cylinder built-in motor, the end cap shutoff of the two ends of blanket roller, the sealing of axle core passes end cap, is evenly equipped with air-vent on end cap, and it is aeration-cooling that fan page is equipped with at the two ends of the interior axle core of end cap.
The treadmill of described cylinder built-in motor, the end part seal of blanket roller and metal tube is with rubber seal, and blanket roller, metal tube and rubber seal form Sealed sandwich, are marked with cold oil or liquid cooling in interlayer.
The utility model compared with prior art, tool has the following advantages: motor and blanket roller are united two into one, serve as blanket roller and drive the operation of treadmill belt by the rotor of motor, save the polywedge bet of transferring power, change motor---polywedge bet---the traditional structure form of multi-wedge belt pulley---roll shaft---treadmill belt that in the past used, simple and compact for structure, be convenient to install, reduce the features such as manufacturing cost is energy-saving and cost-reducing.

Detailed description of the invention
In the embodiment shown in Fig. 1,2: motor and blanket roller 1 are united two into one, the rotor of dc motor is front roll 1, axle core 5 is the stator of motor, power supply lead wire 4 is drawn by axle core 5, end cap 6 shutoff for the two ends of blanket roller 1,5 sealings of axle core pass end cap 6, are evenly equipped with air-vent 7 on end cap 6, and fan page 8 is equipped with at the two ends of the interior axle core 5 of end cap 6.In the time that blanket roller 1 turns round, air gives vent to anger to reach the object of heat radiation by one end air inlet, the other end.
In the embodiment shown in Fig. 1,3: motor and blanket roller 1 are united two into one, the rotor of motor is front roll 1, axle core 5 is the stator of motor, power supply lead wire 4 is drawn by axle core 5, the outside of blanket roller 1 is set with a metal tube 9, and blanket roller 3 is with the end part seal of metal tube 9 with rubber seal 10, and blanket roller 1,10 and rubber seal 9 form Sealed sandwich, in interlayer, be marked with cold oil, reach the object of cooling.
Cavity structure as shown in Figure 4, comprises that the cavity structure 11 of sealing has gap 13 and flexible hose 12 is set, and triplicity is got up, and further increases acoustic absorptivity and acoustic resistance, widens its sound sucting band simultaneously.Tube bank rearranges with the flexible hose 12 of gap 13 diameter identical elongated by some, the length of flexible tube bank is not subject to the dark restriction in cavity structure chamber (can be designed to different in size, with the acoustic absorptivity under resonance tuning frequency and change different frequency, reach modulation and widen the object of sound sucting band), it is dark that the length of each root flexible hose 12 is greater than chamber.Because elongated pipe is arranged in enclosed cavity and embeds the surface of cavity structure, thereby increase acoustic absorptivity, in enhancing, effective absorption of low-frequency noise, improve high frequency acoustically effective simultaneously, widen sound sucting band.
