Induction analytic than surplus quantity coupling loading and unloading cases

Induction analytic excelled surplus quantity of coupling loading and unloading of case 1, surplus quantity coupling coupling as the main fittings of transmission device and the device is widely used in machinery and equipment. According to the work requirements of different equipment and part of the equipment of the coupling and the related components for greater than surplus quantity and collaboration between, like the tension roller in the metallurgical steel mill, its coupling all for surplus to cooperate, especially electricity galvanized, hot dip galvanized unit machine before and after the tension roll group, and its coupling are keyless connection, interference quantity is very large. To meet the requirements of production to the corresponding equipment, related equipment should be replaced periodically, so the corresponding coupling need to tear open outfit on a regular basis. 2, the major disassembling process in this paper, we describe the scene of the induction of maintenance than surplus quantity coupling disassembling. At the scene of the maintenance, the equipment and the space limit, can't be equipped with large special device. For greater than the removal of surplus quantity coupling, main is to reduce the interference between the coupling and cooperate with the axial surface, usually adopts high voltage open or flame heating way to get up, then use hydraulic ramallah extraction separation coupling and spindle; When installation, general of the coupling by flame or low frequency induction heating, make the coupling after heating with aperture is greater than the shaft diameter, easily after coupling sets into the main shaft position accordingly. 1 high pressure oil rose open removal process in metallurgical mills keyless greater than surplus quantity tension roller coupling as an example, the coupling set has used in the high pressure oil rose open oil, visible high pressure oil is rolling out a similar equipment dismantled the recommended process. As shown in figure 1, in the Settings are well versed in its inside and outside surface of the coupling oil, high pressure oil inlet is connected with the outer surface of the coupling, drive the oil supply device ( Generally for manual ultra-high pressure pump, such as SPAKD UHP2800, work pressure force can be up to 2, 800 bar) , super high pressure hydraulic oil through the coupling of the oil into the shaft coupling, and the spindle of the mating surface and to establish a strong tension, reduced the amount of its interference, and the matching surface lubrication, greatly reduces the drawing force of the disassembled, so as to facilitate removal of this coupling. But in the actual repair work, we are faced with the coupling of artifacts that have been linked to or instead of disassembling times, their mating surface scratches and as the growth of the life cycle has become even more so, make the super high pressure hydraulic oil will pass from mating surface scratches and cannot build up tension, so the technology can't meet repeatedly use greater than surplus quantity of shafts dismantling requirements, so use less at the scene of the maintenance. 2 flame heating disassembling process influenced by the scene actual situation, the induction field than surplus quantity coupling tear open outfit, often by flame heating. It has simple process principle, it is using flame ( Generally for oxyacetylene flame) To heat coupling, making thermal coupling, to meet the requirements of its demolition and installation to cooperate. Relatively slow due to the flame heating, the coupling is in the process of heating, fire baking heat of shafts at the same time, through heat transfer function, corresponding to the principal axes of 1262 also is heated, if coupling size is larger, or a flame heating power is insufficient, the heating time is too long, the spindle has been heated to high temperatures, the coupling and the amount of interference fit between the spindle will not reduce, so can't meet the requirements of the demolition; The flame heating usually by manual operation, on the other hand, a gun in the workpiece surface moves back and forth, it is difficult to even heat on the coupling area of the high temperature material softening, parts of low temperature is not up to par value, in the process of forced drawing easy to cooperate with the damage, eventually leading to failure drawing; On the other hand flame heating is similar to the non-standard heat treatment, the physical and chemical properties of the coupling is adverse, repeated heating will lead to coupling theory of the real life is much lower than life. 【 See who else in WTR bearing 】 : zhejiang hailiang CheJiaXing cement China wind power in China's hubei province is fitting click to see more customer case!
