Large bearing

Using large bearing mechanical have? Large bearing is commonly used in machinery, has the following characteristics: one, its structure is larger, popular point is the mechanical volume will be larger. Because of bearing the equivalent of human joints, joint by the size of the large so people will be larger. Second, in the mechanical shaft speed, low speed overloading, because big bearing its most significant advantage is able to withstand a larger load. Three, general large bearings have to adapt to bad environment requirements. Because of bearing, for small dust particles and impurities, is not so easy to damage the bearing. Meet the above conditions are: crane, excavator, shield machine, rolling mill, converter, gear box, wind power, wind power spindle mill, crusher, cement, cement roller press and large low speed shaft gear box and so on. Large bearing with what heating large bearing installation method generally has two kinds: 1. Bearing inside diameter for the cylindrical hole, can use hot pack, such as electric induction heater or oil bath heating. Electromagnetic induction heater can use SKF, oil bath heating must pay attention to keep clean, pay attention to the purity of oil. 2. Bearing inside diameter for the cone hole, can use hydraulic installation method, with the hydraulic pump, hydraulic nut tool. Large bearing with what method remove? When the shaft and bearing in the process of removal of bearing damage, the general loss of time cost and material cost will happen. In addition, using the wrong tools and technology engaged in disassembly operations may also make the operator at risk, especially the risk caused by excessive force. Introduces the necessary preparation and the application of the cylinder and cone base removal methods. Methods including mechanical, heat and hydraulic technology.
