Mine Use,scraper Conveyor Speed Reducer

The planetary reducer is installed in the head and tail of the conveyor to adjust the working speed of the sprocket shaft set and the carrying capacity of the scraper chain, so as to suit the working needs of different design power and rotating speed of the scraper conveyor. According to the different structural characteristics of the reducer, the use of different, its general classification is as follows: 1. According to the series of transmission, it is divided into single-stage reducer and multi-stage reducer 2. According to the type of transmission, it is divided into fixed-axis reducer and planetary reducer 3. According to the layout requirements of scraper conveyor, it can be divided into parallel layout type and vertical type Scraper reducer is mainly used for planetary reducer. Compared with fixed-shaft gear transmission, planetary gear transmission has more compact structure, more stable transmission, larger transmission ratio of the same series, and better performance in bearing capacity. But because this kind of decelerator usually has three or four planetary wheels in the planetary frame design, its structure is more complex, the parts processing precision request is higher. The main parts of scraper planetary reducer include one shaft assembly, two shaft assembly, three shaft assembly, output tie rod assembly, sun wheel, inner gear ring, box assembly, cooling device and lubrication system. Above is the scraper planetary reducer structure characteristics. Want to know more coal machine accessories, please continue to pay attention to us. Henan Shuangzhi Machinery Equipment Co., LTD.

Reducer has the characteristics of large bearing capacity, high transmission efficiency, generally used for input shaft and output shaft are arranged in a vertical direction of the transmission device. For the coal mine scraper reducer oil leakage of the reasons are usually only two points: sealing ring damage and the box body joint surface is not strict. Most of the oil leakage of the scraper reducer is caused by the damage of the sealing ring. After long-term operation and the influence of underground coal mine environment, the sealing ring will inevitably wear down, resulting in poor sealing effect and oil leakage. However, it can be well solved by simply replacing the sealing ring. For the box body joint surface lax than the former slightly less, this situation is mostly the upper and lower box body lax, the end pressure cap is not tight, may be caused by the assembly irregularities, may also be caused by the long-term operation of bolts loose, the solution is to tighten all parts of the bolts. Henan Shuangzhi machinery specializes in the production of all kinds of coal machine accessories: reducer 1 shaft assembly, 2 shaft assembly, 3 shaft assembly, 4 shaft assembly, etc., welcome to consult and cooperate!

Scraper reducer is a special reducer produced for the coal industry, with high reliability, large bearing capacity, strong safety and other characteristics, with the role of reducing speed and increasing torque. Double record coal machine can produce reduction gear and its accessories, such as reduction gear one axis assembly, reduction gear two axis assembly, reduction gear three axis assembly, reduction gear four axis assembly. Scraper reducer is mainly used for planetary reducer. Compared with fixed-shaft gear transmission, planetary gear transmission has more compact structure, more stable transmission, larger transmission ratio of the same series, and better performance in bearing capacity. But because this kind of decelerator usually has three or four planetary wheels in the planetary frame design, its structure is more complex, the parts processing precision request is higher.

Scraper speed reducer is mainly composed of upper box, lower box, one axis assembly, two axis assembly, three axis assembly, four axis assembly, bearing, gear, seals and so on. At present, the different parts of the scraper reducer are mainly lubricate by grease, oil immersion and splash. The main lubricants of plate scraper reducer are no. 150 extreme pressure gear oil or No. 22 hyperbolic gear oil and No. 2 sodium base grease. The bearings and gears on the second, third and fourth shafts of the scraper reducer are lubricated by splashing oil. Scraper reducer in the oil, follow the strict and accurate principle, can not be mixed with different grades of lubricating oil. Lubricating oil shall be loaded from the top viewing hole when the scraper reducer is being lubricated, and the amount of lubricating oil shall be kept at one third of the circle arc bevel gear. After the new reducer is put into use for 200 hours, the oil inside the reducer should be released, cleaned and changed. After the initial cleaning and oil change, wash and oil change every 1000 hours. When the reducer is working, it should be cleaned and changed for oil when the following conditions occur visually. Oil appears to deposit dirt, particulate sediments. The oil darkens, turns black, and even gives off an unpleasant smell. Brown gelatinous material appears on parts of reducer, corrosion marks appear on the surface of parts. Oil body flow difficulty. There are some situations need to be tested, in the reducer lubricating oil sundry content more than 2%, metal abrasive more than 0.5%, water content more than 2%, the need to clean oil change. In strict accordance with the requirements of the timely scraper reducer lubrication, cleaning and oil change can prolong the cycle of the reducer. Henan Shuangzhi Machinery Equipment Co., LTD. Production reducer, axle assembly, two axle assembly, three axle assembly, four axle assembly, arc bevel gear, if there is a need, you can telephone consultation, Shuangzhi machinery is looking forward to working with you.

Sprocket assembly is the key transmission part of scraper conveyor, and its running performance has become the condition to improve the performance of scraper conveyor. Sprocket assembly is centralized with oil tank storage thin oil lubrication, lubricating oil for N320 extreme pressure gear oil. The lubricating oil enters the sprocket assembly through the hose of the oil tank, making it more convenient for refueling and extending the service life of the shaft assembly. Among them, sprocket is forged by alloy steel. In order to enhance its strength and extend its service life, it adopts tempering and surface hardening treatment. Generally after being put into use, it is recommended to replace the sprocket installation direction and change its bearing surface to extend its service life when the bearing side tooth surface is badly worn. Check whether the sprocket assembly operates normally, whether there is oil leakage, oil temperature should not exceed 90â??, whether the auxiliary oil tank oil level is insufficient, etc. Let the scraper conveyer operate normally, Henan Shuanzhi welcomes you to inspect.
