Abstract
The utility model relates to a flexible wheel disc gear, which is suitable for various mining machines with a high speed and a heavy load, construction machines, and mechanical equipment which requests vibration and noise reduction. By using the technique, the entire steel gear is divided into a gear ring, a hub, and a flexible spoke plate. The flexible spoke plate is formed by special steel keys which are inserted into rubber. The gear ring and the hub are connected together by the flexible spoke plate. The utility model has simple structure and durability. The utility model can work under the condition of big modulus, high speed, and heavy load, which can reduce noises by more than 10 dB, high frequency noises by more than 15-20 db, vibrations by more than 50%, and tooth root stress by 15% in general. The flexible wheel disc gear can reduce the noise pollution of the environment and can improve labor conditions.
Description
The flexible web gear that the utility model relates to is particularly useful for the aspect such as mining machinery, building machinery of various high-speed overloads and the various machinery that needs vibration damping and noise reduction.
Gear is a transmission of power part the most frequently used in the machinery, also is simultaneously the main root that produces vibration and noise.According to 87 years collection of thesis volumes translated in the Chinese language of data " Inter-Noise " P71 page or leaf, provide a kind of mating face to bore several holes, garden at gear ring and wheel hub, rubber is inserted in the hole and mating face, noise reduction is preferably arranged during transmission, but in this structure, it is bigger that rubber bears shearing stress, under the situation of heavy duty and big modulus, rubber is sheared destruction very soon, is only applicable under the situation of little modulus, underloading, be not suitable for big modulus, at a high speed, down work of heavy duty.
In view of the problem that prior art exists, the purpose of this utility model is to design a kind of simple in structure, be applicable to big modulus, at a high speed, heavy duty work down, have vibration damping, noise reduction is flexible web gear efficiently.
Flexible web gear of the present utility model is divided into gear ring, wheel hub two-part to whole steel gear, and rubber is inserted on the mating face, it is characterized in that: form flexible web in the middle of embedding rubber with special steel key, by flexible web gear ring and wheel hub are combined as a whole.After wheel hub and gear ring process, embed special steel key and gum filler, form through hot-press vulcanization.During use, can be meshed, also can be meshed with two flexible web gears with single flexible web gear and other gear.
Flexible web gear of the present utility model, prior art corresponding to affiliated technical field, have rational in infrastructure, simply, be not subjected to shearing stress, be applicable to big modulus, at a high speed, work under the situation of heavy duty, when transferring power, its moment of torsion is mainly born by steel key and rubber, steel key bears shearing stress, and the rubber stress that only is squeezed is because rubber is a kind of widely used vibroisolating material, has better elastic and enough intensity, under various stress phases the distortion all bigger, under the alternating stress effect, be not prone to fatigue phenomenon, have very big internal friction, under the effect of power, can the absorption portion energy and very fast inhibition impact shock.This technology can reduce more than the noise 10dB after tested, and high-frequency noise can reduce more than 15～20dB; Vibration damping reaches more than 50%; Root stress generally can reduce about 15%.Reduce pollution from environmental noise the working life of energy prolonged mechanical equipment, improves working conditions.Be with a wide range of applications.

Fig. 2 is a flexible web gear side-looking sectional view.
1---gear ring; 2---rubber; 3---steel key; 4---wheel hub.
Below in conjunction with accompanying drawing an embodiment of the present utility model is described further:
Flexible web gear of the present utility model is by gear ring 1, and wheel hub 4 and flexible web are formed, and flexible web is made up of 4 special steel keys 3 and four butyronitrile rubbers.By flexible web gear ring 1 and wheel hub 4 are linked together.Flexible web is after wheel hub 4 and gear ring 1 process.Embed special steel key and gum filler, form through hot-press vulcanization.Can single flexible web gear and ordinary steel gear mating engagement during use, also can be meshed with two flexible web gears.
