Motor for a long time, repair personnel focus on electrical parts (Mainly winding)The mechanical parts of the process, ignore,Mainly rolling bearing)Device technology. In recent years, the rising number of defect rolling bearing on the market, resulting in failure of mechanical parts significantly more. Mechanical part of fault repair mainly rolling bearing replacement device. Traditional motor textbooks, this paper introduces struck iron bars with a hammer impact rolling bearing inner sleeve to device, in the actual operation, the process work, effort, very brief hurt repair personnel, often will be rolling bearing damage, damage. Due to the impact of the bearing inner sleeve was is uneven, the inner sleeve is often go broken or deformation, accelerate and coat between the ball and roller wear and premature bearing will damage, the electrical JiSao chamber, also often will be fully sealed, half sealing grease baffle ring hedge or deformation (The motor is given priority to with devices using fully sealed rolling bearing)。 Bearing on the job, grease was the effect of pressure, temperature, will spill over to the winding, especially in high speed, heavy, high temperature under the condition of the most significant, such as the hidden danger, eventually because he bore or winding is too dirty and burning motor, both affect yield, and can form economic losses. So the rolling bearing device should not be ignored, it is necessary to advance device technology of rolling bearing. Motor used in the rolling bearing points fully sealed type and seal type and seal type, mainly use full sealed bearing. On the electric tool motor, commonly used: 608, 629, 200, 201, 202, 203 and other types; On the household micromotor, commonly used: 608, 629, 200, 201, 202, 203, 204, 205 and other types; In car motor, are commonly used: 201, 202, 203, 204, 303, 304, such as type; In single and three phase on the small and medium-sized motor, commonly used: 203, 204, 205, 208, 303, 304, 305, 306, 308, 309 type, etc. The car system processing & otherBlunt cone bearing & throughout; (Special tools)Shape as shown in figure 1. Machining dimensions are shown in table 1. , bearing, the device can be set on the coated with a thin layer of grease, use the hammer hit bearing cylinder not open end, bearing blunt cone of end face and the bearing inner sleeve end surface contact area is large, uniform stress, save labor, this device to the operator and safe, will not damage, damage to the bearings. After several years of actual use, can advance work efficiency several times, to ensure that the service life of the bearings, motor. (FIG. 1)Bearing blunt cone (Special tools)Outline drawing (Table 1. )Bearing salt barrel processing scale summary: rolling bearing is the precision parts, as long as the correct device, the ability to ensure that the service life. Bearing salt barrel processing are briefly introduced in this paper, easy to use, can advance work efficiency several times, not only the right motor with rolling bearing device, also suitable to other devices using rolling bearing device. Friends at trial, and expensive mindset is put forward.
