At this time, the demand is to control the heating temperature; usually the bearing is heated to 80 ° C; up to 100 ° C. It is enough. Exceeding 120 °C will lead to the appearance of bearing tempering; resulting in a decrease in the hardness and accuracy of the ferrule.
First, the commonly used heating methods are:
1, electric heating plate heating method:
Place the bearing on a hot plate with a temperature of 100 °C for a few minutes; this method is the most succinct; if it is turned over several times, the bearing can be heated evenly; and the power is also high; the large-capacity bearing can use this method.
2, electric furnace heating method:
The bearing is placed in a closed active temperature control electric furnace for heating; uniform heating; precise temperature control; fast heating; suitable for a batch of heating many bearings.
3. Induction heating method:
The induction heater can quickly, securely and cleanly heat the bearing to the required temperature; this is uniquely suited to the case where the inner ring is tightly co-operated; because only the inner ring is heated; the outer ring is less heated; Easy to install on the shaft; also easy to fit into the seat hole.
4, bulb heating method:
Use a 50W bulb to heat the bearing; ensure that the heating temperature is around 100 °C; smaller bearings can be placed directly on the bulb; larger bearings can be placed in the cone of the bulb; the cone prevents heat loss from the bulb; Uniform heating. The cone cover can be adjusted up and down; in a certain scale, it can be used to heat the bearings of different sizes. If you choose a far-infrared bulb; pay attention to the direction of the bulb should be downward; avoid infrared rays is not conducive to human eyes. Imported pump A kind of bulb can save energy. The bulb heating method is suitable for occasions where the quantity is small and not often needed to heat the bearing; the ordinary bulb can also be used for lighting; in addition, no other equipment is required.
5, oil tank heating method:
This is a widely used traditional heating method; the oil trough is provided with a metal mesh at a distance of 50 to 70 mm from the bottom; the bearing is placed on the net; the large bearing is to be hung with a hook. The bearing should not be placed directly on the bottom of the groove; Part of the heat is too high; or the dirt deposited at the bottom of the tank enters the bearing. The key points of the oil tank heating method are as follows; mineral oil with good non-corrosive thermal stability should be used; the best is transformer oil; oil and container should be kept clean. The capacity of the oil tank should be determined by the size of the heated bearing and the amount of oil; if it is too containerized, the 诹 é‡ é‡ ç° ç° ç° æ¹ƒèƒ«å²¢ 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢 湃胫岢
Second, the key to the heating device method:
1 The heating temperature should be handled properly; if the temperature is too high, the bearing will be damaged; if the temperature is too low, the ferrule will be inflated in a large amount; the effect is not obvious. The heating temperature of 80~1000 °C will produce a large amount of thermal expansion of the inner ring inner diameter; For bearings with normal interference; it is already enough.
2 arrive at the required heating temperature; it is necessary to carry out the device as soon as possible; avoid the cooling and the device is difficult.
3 The bearing is also shortened in the width direction when cooling; therefore, the device must apply a certain pressure to press the inner ring to the shoulder; and after cooling, test with a very thin feeler gauge; can the inner ring end face and the shaft There is a gap between the shoulders. Totally; the butterfly is demanding, agile and precise.
