Description

The improvement drive mechanism of treadmill

The utility model system is about a kind of improvement drive mechanism of treadmill, mainly be that motor with the band drive shaft members of running in order to transmission is altered to built-in group and establishes, cooperate relevant gear rotation fitting and axis body and constitute direct transmission mode, can replace the external belt transmission structure of known motor, not only can appropriateness simplify its structural complexity, more improve its dynamic horsepower and usefulness relatively.

Because the modern is because of being subject to the narrow and work in living space factor such as have much to do, cause generally lacking motion and cause " obesity " problem, so the dealer develops various exercise and fitness equipments, the equipment that can provide the user to select different start patterns is on demand implemented motion, to reach the purpose of sport and body-building.

And in numerous exercise and fitness equipments, motion and exercise in response to different parts, on its structural design, also be not quite similar, wherein " treadmill " is to reach simulation running action with the circulation that utilizes the band of running to be celebrated, can promote the coordination and reinforcement cardio-pulmonary function of whole-body muscle because of the running effect, exercise and fitness equipment compared to general privileged site, its applicable object is not subjected to restrictions such as age, build, become the most general a kind of sports equipment, the utility model promptly is the improvement design of being done at its transmission mechanism aspect.

The transmission mechanism of known treadmill, see also shown in Figure 1, it mainly is before treadmill pedestal 10, back-end location sets up a drive shaft members 11 and a driven shaft spare 12 separately, in two

parts

11,12 is to open to establish one and run and be with 13, and at the front end drive shaft members 11 coaxial belt pulleys 14 of establishing, it is fixing for a motor 16 that pedestal 10 positions of drive shaft members 11 belows are established a seat board 15 in addition, motor 16 axles borrow a belt 17 and belt pulley 14 cover groups to constitute continuous action relation again, when starter 16 runnings, via this drive shaft members 11 of belt 17 driving pulleys 14 gained interlocks, and then make this running be with 13 generation circulations to rotate, reach the function action of treadmill thus, and can run with 13 the speed that rotates by the controllable rotation speed system of adjusting motor 16, provide the simulation of user's friction speed to run.

With regard to above-mentioned treadmill structure, its transmission mechanism has following disappearance in design:

One: this drive shaft members of switching transmission that cooperates belt pulley because of its motor system via belt, the switching transmission of this kind indirect type not only can be lost part horsepower because of the parts conversion, more, its motor influences transmission smoothness and transmission efficiency, real nonideal design because of having the loose problem of wearing and tearing.

Its two: its motor and driving member are adopted separate design, members bindings such as belt and belt pulley must be joined again and the interlock state could be constituted, and cooperate the motor setting and need set up a fixing seat board in addition, cause its except the horsepower consume that faces in transmission and efficient are clear wait lack, more cause the difficulty and the cost problem of maintenance, assembly, be not inconsistent the industrial economy benefit because of the complexity of its structure.

That is, the drive mechanism of known treadmill is to the greatest extent desirable because of design, causes it also to have the disappearance of demanding urgently improving in practicality and industry utilization, and for this reason, people expect the kind of drive that can provide even more ideal, to promote its practicality and industrial utilization.

Because the disappearance that the indirect type transmission of known treadmill transmission mechanism is faced, the creator is based on the many years of experience of being engaged in relevant industries and technology, the spy sets about the research and development design, after design, trial-production and repeatedly testing, improve, finally grind and create improvement drive mechanism of the present utility model, be that its main purpose is the design of forming by drive shaft members and motor drive connection, the spy can appropriateness simplify its structural complexity and improve its transmission efficiency relatively, to meet economic benefit and the practicality that industry is utilized.

For reaching aforementioned purpose, the utility model is on structural design, mainly be that motor with the band drive shaft members of running in order to transmission is altered to built-in group and establishes, cooperate relevant gear rotation fitting and axis body and constitute direct transmission mode, so that replace the external belt transmission structure of known motor, not only can appropriateness simplify its structural complexity, more improve its dynamic horsepower and usefulness relatively.

The improvement drive mechanism of a kind of treadmill of the present utility model, before comprising the treadmill pedestal, back-end location sets up a drive shaft members and a driven shaft spare separately, between two parts, open and establish the running band that the do circulation that can control by the rotation of drive shaft members rotates, thereby constitute its basic functional architecture, the drive shaft members that is characterized in treadmill pedestal front end is done the design of hollow structure kenel, plug a motor in the drive shaft members inner space, the axis body of respectively being equipped with a part at the drive shaft members two ends is respectively plugged involution and is consolidated into one, the medial extremity of axis body rank is provided with an adaptor therein, obtain interlock via adaptor and motor spindle, simultaneously to be mat two pivot spares be mounted on treadmill pedestal front position with the axostylus axostyle of two ends axis body to drive shaft members, finish the movable pivot group kenel of drive shaft members and treadmill pedestal, utilize built-in mate gear adaptor of this motor and axis body assembly to constitute coaxial direct transmission, can appropriateness simplify its structural complexity, more can promote its dynamic horsepower and usefulness relatively; Described drive shaft members cover plug axis body and motor are obtained the adaptor of interlock, are a gear rotation fitting, utilize the gear of gear rotation fitting and motor spindle to obtain engagement, drive shaft body and drive shaft members in the lump when making motor running; The power supply wiring system of described drive shaft members built-in motor pulls out via the default path of another axis body, and links to each other the startup of controllable motor and rotating speed with power control; The outer rim cover of described drive shaft members built-in motor is covered with carbon brush holder, can obtain cover group location but unlikely rotation thereupon owing to the isolation of carbon brush holder makes motor and retainer.

The utility model will be helped to understand by following embodiment and description of drawings, but the utility model content can not be limited.
