Product introduction: China famous brand-Weigao reducer ZDY series high-precision hard-toothed cylindrical gear reducer refers to JB/T8853-2001 "cylindrical gear reducer" standard production of external mesh involute helical gear reducer. ZDY (single stage) is suitable for transmissions in which the input shaft and the output shaft are arranged in parallel. The transmission ratio i is from 1.25--6.3, and the nominal power is up to 6666 kW. It can be widely used in metallurgy, mining, lifting, transportation, cement. In the mechanical transmission of plastics, construction, chemical, textile, energy, paper, printing and dyeing, pharmaceutical and other industries.
First, the characteristics
The gear parameters and structural parameters of the series reducer are optimized by computer. The gear material is made of high-quality high-strength low-carbon alloy steel. After carburizing and quenching, the hardness of the tooth surface is high. The hardness of the tooth surface is up to HRC58-62. The processing adopts the grinding process, the precision is 6 grades, the precision is high, the contact is good, and the root root shot peening is strengthened. The whole machine has the characteristics of small volume, light weight, large transmission power, stable operation, low noise, high transmission efficiency, single stage greater than 96.5%, high carrying capacity, long service life, easy to dismantle and easy to install.
This reducer can be used in both forward and reverse directions. The series of reducers are available with water circulation cooling, fan cooling and electric heating.
Second, the scope of use:
The maximum speed of the input shaft is generally not more than 1500r/min.
The circumferential speed of the gear is up to 20m/s
The working environment temperature is -40 to 45 °C. If it is lower than 0 °C, the lubricating oil should be preheated to above 0 °C before starting.
