Hard tooth surface gear transmission mainly include series of parallel axis and vertical axis series, parallel shaft gear reducer is according to the national standard (GBl9004-88) production, optimization design, the sankei shimbun has the international advanced level in the eighty s, it mainly includes ZDY (single stage), ZLY (grade two), ZSY (level 3) and ZFY (level 4) four series, vertical shaft reducer is according to the national standard (JB/T9002-1999) production, is used for the input shaft and output shaft is vertical arrangement of transmission device, it mainly includes DBY, DCY and DFY three series.
- Application Range
The Hard tooth surface gear transmission shall not be more than 20 m/s. Work environment - 40 ~ 50 ℃, if lower than 0 ℃, before the start of lubricating oil should be preheated to 0 ℃ above, the speed reducer can be used in positive and negative two directions. It can be widely used in metallurgy, mining, chemical industry, building materials, lifting, transportation, textiles, paper, instruments, plastics, rubber, construction machinery, energy and other industrial sectors.
The main parameters, such as center distance and nominal transmission ratio, have been optimized and designed. Hard tooth surface gear transmission are made of high quality alloy steel through carburizing, quenching, and, tooth surface hardness up to hrc54-62. Small size, light weight, high precision, large carrying capacity, high efficiency, long life, high reliability, smooth transmission, low noise. Generally use oil pool run, natural cooling, when the thermal power can not meet, can be used for circulating oil lubrication or fan, cooling coil cooling.
Z series Hard tooth surface gear transmission, small size, compact structure, high overload capacity, power up to about 132KW, machine efficiency up to about 97%, small vibration, low noise, high energy saving, selection of high-quality forged steel materials, steel cast iron box, gear surface after high-frequency heat treatment, gear pair after precision processing. Output speed :0.04--810r/min, output torque: up to 18000 N.m, motor power :0.12--132KW.
Oil level Hard tooth surface gear transmission usually uses oil teeth lubrication. Before use, it must be refueled to the specified position (press). When the new reducer is used for the first time, the new oil must be replaced after running-in period of 7 to 14 days (150 to 300 hours). The new oil must be replaced for the second time when it is used for three months. In the future use process, and regular inspection of oil quality, must be replaced at any time containing impurities, pollution, or decomposed, aging deteriorated oil.
The Hard tooth surface gear transmission is usually lubricated by oil pool and cooled naturally. When the working balance temperature of the reducer exceeds 90 C or the load-carrying power exceeds the thermal power PG1, circulating oil lubrication or oil-line lubrication with cooling pipe can be used. When the gear reducer starts after continuous shutdown for more than 24 hours, the gear and bearing should be fully lubricated before they can be loaded and rotated.
