As the blast furnace smelting equipment is becoming larger and larger, the sintering raw material equipment is correspondingly larger. In the case of a large number of sintering raw materials, the reduction gear is used, and the DBY/DCY series conical cylindrical gear reducer is used for the transmission device in which the input shaft and the output shaft are arranged in a vertical direction.
DBY/DCY series conical cylindrical gear reducer is mainly used in belt conveyors and various transportation machines, and can also be used in transmission mechanisms of other general machinery. The gear adopts carburizing, quenching and grinding, and has high bearing capacity and low noise.
Advantages: DBY/DCY series conical cylindrical gear reducer has compact structure, high transmission efficiency, stable operation, large transmission ratio, small size, convenient processing and long service life.
Therefore, with our rapid development, many units have designed and manufactured such DBY/DCY series conical cylindrical gear reducer, and have been increasingly used in defense, mining, metallurgy, chemical, textile, lifting and transportation, construction, food industry and In the mechanical equipment of industrial sectors such as instrument manufacturing, it will be more widely used in the future.
First, the design performance characteristics
(1) The main parameters such as center distance and nominal transmission ratio are optimized, and the main parts and components are interchangeable.
(2) The gears are made of high-quality alloy steel by carburizing and quenching, and the tooth surface hardness is 54-62HRC.
(3) Small size, light weight, high precision, large carrying capacity, high efficiency, long life, high reliability, stable transmission and low noise.
(4) Generally use oil pool lubrication, natural cooling, when the thermal power can not be met, you can use circulating oil lubrication or fan. The cooling coil is cooled.
Second, the scope of application
- The input speed is generally n1 ≤ 1500r/min.
- The peripheral speed of the gear drive is not more than 20m/s.
- Working environment -40-50 °C, if it is lower than O °C, the lubricating oil should be preheated to above 0 °C before starting, the reducer can be used for both positive and negative directions.
- Can be widely used in metallurgy, mining, chemical, building materials, lifting, transportation, textile. Industrial sectors such as paper, instruments, plastics, rubber, construction machinery, and energy.
