Electrical network as the enterprise equipment system important transmission equipment, stepper motor reducer universality oil leakage problems to enterprise field management and safe production caused great influence, therefore, to find effective reduce the solution to the stepper motor speed reducer leakage has become an important problem in industry. (1)Oil added too much stepper motor reducer in the process of operation, the oil pool was badly agitation, lubricating oil and splatter everywhere inside the machine, if the amount is overmuch, make a lot of lubricating oil accumulation in the place such as shaft seal, in combination with surface, lead to leakage. (2)Stepper motor reducer oil pressure rises in a closed in the stepper motor reducer, each pair of gears meshing friction will send out quantity of heat, according to the Boyle trails by specific law, as the lengthen of time running, to gradually rise, slow down the temperature inside the case and the reduction volume inside the case, so the pressure increase, in the cabinet in the lubricating oil splash, sprinkled on the stepper motor reducer casing wall. Because the permeability of oil is strong, under the pressure in the cabinet, which a seal is lax and the oil bleeding out from where. (3)Improper maintenance technology in equipment maintenance, due to the combined surface dirt removal is not complete, or sealant improper selection, seal, not timely replacement seal way, etc. Can also cause oil leakage. (4)Stepper motor deceleration pattern to the unreasonable structural design oil such as the design of stepper motor reducer without ventilation hood, step motor reducer pressure cannot be achieved, due to the pressure in the cabinet more and more high, the spill occurs. For now the European and American countries use sauvy polymer repair materials technical effect is very good, for oil leakage repair more time saving, energy saving, good effect, high sex ratio. Sauvy polymer material has excellent adhesion, oil resistance, and 350% of the tensile strength, overcome the impact of vibration reducer, well solved for many years for the enterprise to solve the problem, save time and effort, the effect is immediate.
