Jiaxing bearing group co. , LTD. | factors affecting grinding machine Lord bearing temperature

There is rotational, have HRB bearing ( ) Jiaxing bearing group co. , LTD. | factors, which affect the grinding temperature of the main bearing of jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Grinding machine Lord high bearing temperature is a common phenomenon, requires the user to cool down in a timely manner. In the process of the use of the mill, what are the factors that affect the temperature of the main bearing? There are many influencing factors, jiaxing bearing below the author resolved one by one to you. 1, the influence of the friction heat hollow shaft and bush relative rotation, the friction heat production, strict, the oil film between the shear and heat, is bearing temperature increases, the value is relatively small. 2, the influence of grinding medium crushing material to generate heat when mill in operation, the work of grinding material accounts for only a small part of the total energy consumption, and most of the energy is transformed into heat and sound energy, therefore, material in get a lot of heat, flows through the hollow axis or slip ring, heat is passed to the bearing shell, can make the main bearing bushing temperature rise significantly, bearing shell temperature can reach 70 ~ 80 ℃ or higher. 3, the influence of mill type because mill type is different, the impact on the bearing temperature rise is different. Wet grinding materials in the slurry, grinding temperature is not high, the material of the main bearing the lowest greenhouse, cement mill discharge of main bearing tile is the highest; Dry raw materials mill wind swept coal mill to feed at the same time also painful hot air, if use preheater waste gas drying of material, inlet air temperature of 350 ℃; If use auxiliary stove, feed gas temperature can reach 450 ℃, the feed temperature of main bearing is the grinding machine. 4, the influence of grinding machine structure mill inlet and discharge screw barrel ( Taper sleeve) And the hollow shaft is equipped with thermal insulation layer between, in order to reduce the material of heat is passed on to the hollow shaft and bush. Some mill heat insulation layer is very thin, and some mill insulating layer is relatively thick. For cement mill discharging main bearing, hope to have the thickness of insulation layer to block the transfer of heat. 5, the influence of ambient temperature by grinding machine grinding machine ambient temperature also affect the temperature of the bearing shell, season, geographical location, for example, even to the degree of ventilation, the workshop will affect the bearing shell temperature. 6, jiaxing bearing main bearing cooling water temperature and the influence of the cooling water mill main bearing water includes two aspects, one is main shaft tile in the water, the second is the main bearing thin oil terminal water cooler water. The water temperature of cooling water meter of water on temperature influence is bigger, especially the water temperature. Because water is different, some plants in the river or lake, some plants with groundwater, so the water temperature of the cooling water is distinct. The water temperature is also influenced by season. 7, the influence of the peripheral thin oil terminal grinding machine Lord bearing thin oil terminal has two effects. A quantity of oil required for the supply to establish dynamic pressure oil film; 2 it is to take away the excess heat and cool the bearing shell. Usually, the main bearing formation pressure of oil film of oil around 6 ~ 10 l/min; 25 l/min is commonly used in our country, some even use the 45 l/min, it contains away heat required amount of lubricating oil. Through the above analysis, the factors leading to higher grinding machine Lord bearing temperature has a lot of, remind the user, in the process of equipment use, should be attention in many aspects, the reasonable control of the temperature of the main bearing.
