Product Description
This product is an external meshing involute helical cylindrical gear reducer produced in accordance with the national standard JB/T8853-1999. The product has been optimized and designed to the international advanced level. This product is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other departments.
Purpose, performance characteristics and model marking of the reducer
1. Purpose Conical cylindrical gear reducers are used for transmissions with the output shaft arranged in a vertical direction. It is mainly used in belt conveyors and various
transportation machinery, and can also be used in the transmission mechanism of various general machinery such as coal,metallurgy, chemical industry, building materials, light industry, and petroleum.
2. Performance characteristics High carrying capacity, low noise, small size, light weight, high efficiency and long service life
3.Parameter range DBY, DBYK, DBZ type reducers each have 12 specifications, the nominal center distance is: 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560mm; each specification has 5 kinds of transmission ratios (8, 10, 11.2, 12.5, 14) two There are 7 kinds of rotation directions and 7 kinds of assembly forms, which respectively form 240 kinds of reducers. DCY, DCYK, DCZ type reducers each have 15 specifications, the nominal center distance is: 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560, 630, 710, 800mm; 31.5, 35.5, 40, 45, 50) two rotation directions, 7 kinds of assembly forms, respectively constitute 660 kinds of reducers. This series of reducers can meet all power requirements of TD type and DX type belt conveyors and other conveyors and the working range of 0.8-6.5m/s belt speed.
4.Structure The first-stage transmission of the reducer is a Gleason spiral bevel gear, and the second and third-stage transmission is an involute cylindrical helical gear. Lubrication of the reducer: Generally, the gears and bearings of the reducer are lubricated by splashing oil in the oil pool and cooled naturally. Only when the working balance temperature of the reducer exceeds the specified value, or the load power exceeds the thermal power, the circulating lubrication or the oil pool lubrication with the cooling pipe shall be used.
5. Model and marking The model of the reducer consists of the form code, the nominal center distance a, the nominal transmission ratio, the assembly form code, and the input shaft rotation direction code. D belt conveyor type code, B-secondary transmission, c-third transmission, Y-hardened gear, Z-medium hardened gear, K-output shaft is hollow shaft
