Cylindrical gear reducer is a kind of gear reducer. According to the principle of gear reducer, it is a mechanical transmission device for reducing speed and increasing torque. It uses the speed converter of gear to reduce the rotation number of motor to the required rotation number and obtain large torque. Cylindrical gear reducer is a kind of precision machinery. Its purpose is to reduce speed and increase torque. It is commonly used in mining, port, aviation, construction, crane, mechanical equipment, automobile and other fields.
Structure of cylindrical gear reducer:
Cylindrical gear reducer is mainly composed of parallel shaft gear, cylindrical gear, sealing ring, transmission shaft and box. Its structural characteristics are divided into primary cylindrical gear reducer, secondary cylindrical gear reducer, tertiary cylindrical gear reducer and multistage gear reducer. Each level is composed of multiple large and small gears. When the transmission requirement is I > 10 (I represents the transmission ratio), secondary cylindrical gear reducer shall be adopted. The two-stage cylindrical gear reducer shall be used when I: 8-50 and the sum of high and low speed center distance is 250-400mm. The three-stage cylindrical gear reducer is used for large transmission demand. The above conclusions show that the more stages of cylindrical gear reducer, the greater the reduction ratio, the lower the output speed, the greater the torque, the greater the noise, and vice versa.
Performance characteristics of cylindrical gear reducer:
Small volume, light weight, high precision, large bearing capacity, high efficiency, long service life, high reliability, stable transmission and low noise. Generally, oil pool lubrication and natural cooling can be used. When the thermal power is not satisfied, circulating oil lubrication or fan can be used. Cooling coil cooling. The working environment can be - 40-50 ℃. If it is lower than 0 ℃, it can work normally in special environment. Cylindrical gear reducer can design and customize the power and performance of gear reducer according to the needs of practical application.
