Timing Belt Pulley Keep The Exact Gear Ratio

Timing Belt Pulley  belonging to the hub parts, generally relatively large size, manufacturing process generally to casting, forging the main. The general size of the larger design for the casting method, the material is generally cast iron (casting performance is better), rarely use cast steel (steel casting performance is poor); generally smaller size, can be designed for forging, materials For steel. Timing Belt Pulley s of the indicators and materials used to meet the requirements can be achieved under the premise of minimizing the raw materials, the process is feasible, the lowest cost of the principle of choice! Timing Belt Pulley s are mainly used for long-distance transmission of power occasions, such as small diesel engine power output, agricultural vehicles, tractors, cars, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging beds, some small horsepower motorcycle power Transmission, agricultural machinery power transmission, air compressor, reducer, reducer, generators, ginning machine and so on.

The Timing Belt Pulley  drive has the advantages of simple and easy adjustment of the belt Timing Belt Pulley  drive. The Timing Belt Pulley  drive is not suitable for the manufacture and installation of the Timing Belt Pulley  as the belt drive. The belt Timing Belt Pulley  drive is very smooth and low vibration and low vibration. With the function of overload protection; Timing Belt Pulley  drive two axis center distance adjustment range. The belt drive has the following advantages: the Timing Belt Pulley  drive has elastic sliding and slipping, the transmission efficiency is low and can not maintain the accurate transmission ratio; the Timing Belt Pulley  transmission passes the same large circular force when the contour dimension and the shaft pressure are larger than the meshing transmission; Of the shorter life expectancy. All kinds of mechanical equipment, such as the size of the Timing Belt Pulley  and other sizes are based on their own with the reduction ratio, according to the speed of work and motor speed design. Working speed / motor speed = drive wheel diameter / driven wheel diameter * 0.98 (sliding coefficient), such as the use of steel as the material Timing Belt Pulley , the required linear speed is not higher than 40m / s, such as the use of cast iron materials, 35m / s, motor speed and Timing Belt Pulley  diameter conversion ratio, speed ratio = output speed: input speed = load Timing Belt Pulley  pitch circle diameter: motor Timing Belt Pulley  pitch circle diameter. The diameter of the pitch circle is the same as the reference diameter, diameter is 2h = pitch circle diameter, h is the depth of the groove on the reference line, the V zone h of different models is different, YZABCDE, the groove depth on the baseline is h = 1.6 2 2.75 3.5 4.8 8.1 9.6. The Timing Belt Pulley  pitch circle diameter is the theoretical diameter of the Timing Belt Pulley  pitch position, somewhat like the indexing circle diameter of the gear, generally indicated by the PD, and the outer circle is generally denoted by OD. The different groove pitch circle is different from the outer circle conversion formula. SP2: OD = PD + 4; SPA: OD = PD + 5.5; SPB: OD = PD + 7; SPC: OD = PD + 9.6. SPB: OD = PD + A or SPA Timing Belt Pulley  with a minimum outer diameter of 80mm, such as less than the size, especially in the case of high speed, the belt prone to stratification and bottom cracks and other problems. SPZ belt, the ferry can not be less than 63mm. At the same time pay attention to the belt installation techniques and tension, too easy to slip, too easy to damage the belt and bearings.
