Performance characteristics and application skills of hardened gear reducer

Hard tooth surface reducerIt is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing hard tooth surface reducer, pharmaceutical and other fields.

The hard-tooth surface reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the required number of revolutions and has a larger torque device.

Hard tooth surface reducer refers to the reducer whose internal gear hardness is> 350HBS, and the small and small gears have been quenched or carburized. Is a relatively refined For dense machinery, the purpose of using it is to reduce the speed and increase the torque. It is suitable for high-speed shafts where the speed is not more than 1500 rpm, the gear transmission peripheral speed is not more than 20 m/s, and the working environment temperature is -40℃—45℃ In the environment, the gears of the hard-tooth surface reducer are made of high-strength low-carbon alloy steel by carburizing and quenching. The tooth surface has high hardness. The gears adopt CNC grinding technology, which has high precision, good contact, high transmission efficiency and stable operation. , Low noise; small size, light weight, long service life, high carrying capacity; easy to disassemble and inspect, easy to install.

Its advantage is that the gear design is carried out from the two aspects of gear tooth surface pressure and tooth root strength, thereby greatly enhancing the hardness and precision of the gear, which can greatly reduce the weight of the reducer and make the reducer more compact In addition, the performance of the reducer has also been greatly improved, and the transmission efficiency has been improved by a level. On the other hand, the cost of user maintenance and repair is greatly reduced. With the continuous development of gear processing technology and the application of computer design, the development of world transmission technology tends to adopt hard-tooth gear transmission.

Four use skills of hardened gear reducer reducer:

1. During work, when the oil temperature rises above 80℃ or the oil pool temperature exceeds 100℃ and abnormal noise is found, stop using it, check the cause, remove the fault, and replace the lubricating oil before continuing to run .

2. When changing the oil, wait until the reducer has cooled down and there is no danger of burning, but it should still be kept warm, because after complete cooling, the viscosity of the oil will increase and it will be difficult to drain the oil. Note: Cut off the power supply of the drive unit to prevent accidental power-on.

3. After 200~300 hours of operation, the oil should be changed for the first time. In the future use, the quality of the oil should be checked regularly, and the oil mixed with impurities or deteriorated should be replaced in time. Under normal circumstances, for a long-term continuous work reducer, the oil should be changed after 5000 hours of operation or once a year, and the oil should be changed before the long-term deactivation of the reducer. The reducer should be added with the same oil as the original brand, and must not be mixed with oils of different brands. Oils with the same brand but different viscosity are allowed to be mixed.

Fourth, the user should have reasonable use and maintenance rules and regulations, and carefully record the operation of the reducer and the problems found during the inspection. The above regulations should be strictly implemented.
