Timing Belt can be divided into neoprene by material and add the textile rope Timing Belt, and polyurethane adds the steel wire Timing Belt, by toothed arrangement surface, can be divided into single cog Timing Belt and double cog synchronous belt again.Toothed belt transmission has velocity ratio accurately, without slippage, can obtain constant speed ratio, but precision drive, stable drive, the energy shock-absorbing, noise is little, and the transmission speed ratio scope is large, generally can reach 1: 10, allow linear velocity can reach 50m/s, transmission efficiency is high, generally can reach 98 ℅-99 ℅.Transmitted power is from several watts to hundreds of kilowatts.Compact structure is applicable multiaxis transmission also, and tension force is little, does not need to lubricate, pollution-free.During motion, be meshed with the teeth groove of belt wheel with tooth and transmit motion and power, be a kind of engagement driving, thereby there are the various characteristics of gear transmission, chain transmission and flat belt driving.Be widely used in the fields such as automobile, weaving, printing packaging equipment, needling equipment, office equipment, laser engraving equipment, tobacco, financial machine and tool, light of stage, communication food machinery, medical machinery, steel machinery, petrochemical industry, instrument and apparatus, various precision machine tools.Existing belt wheel is unreasonable because its structural design obtains, and causes vibrating greatly when work, and noise is large, affects the life-span.
Summary of the invention
The object of the invention is to overcome the vibration when work of existing synchronous pulley large, the problem that noise is large, designed a kind of synchronous pulley with low noise, low vibration function, this synchronous pulley simple in structure, principle is easy, by the arc gear wheel arranged, vibrate greatly the problem that noise is large in the time that work can being solved.
Purpose of the present invention is achieved through the following technical solutions: a kind of synchronous pulley with low noise, low vibration function, comprise the belt wheel body, evenly be provided with several band gear teeth on the outer wall of described belt wheel body, tooth top with the gear teeth is arc surface, and arc surface and form and be smoothly connected with the sidewall of the gear teeth; Be provided with positioning hole on one of them end face of described belt wheel body, and the dead in line of the axis of positioning hole and belt wheel body.
Further, the bottom surface indent of described positioning hole forms installs through hole, through hole is installed and is run through the belt wheel body, and the axis of through hole and the dead in line of positioning hole are installed, and the diameter that through hole is installed is less than the diameter of positioning hole.
Further, the inwall indent of described positioning hole forms several keyways, and the two ends of keyway are communicated with opening end and the bottom of positioning hole respectively, and the center line of keyway is parallel to each other.
Further, the inwall of described keyway is cambered surface.
Further, the quantity of described keyway is three.
Further, in described keyway wherein the inwall indent of two keyways form screw thread, the two ends of screw thread are connected with bottom with the opening end of positioning hole respectively.
In sum, the invention has the beneficial effects as follows: this synchronous pulley simple in structure, principle is easy, low cost of manufacture, by the arc gear wheel arranged, in the time of can solving work, vibration is large, the problem that noise is large, installation simultaneously is more stable, has extended the working life of synchronous pulley.
