The summary put forward a kind of bearing to assemble add lukewarm new method, report imposes lukewarm standard, discussed report to increase the good point of lukewarm law. Distribution of keyword bearing outfit adds lukewarm acetylene oxygen to classify date TG95 　 to change the method with the commonnest bearing has two kinds: One kind is to use acetylene oxygen to be added directly to bearing lukewarm; Another kind is right small-sized bearing uses oily dip to add lukewarm, achieve heat to bilge, enlarge bearing internal diameter, so that assemble. These methods received wide application in long-term equipment maintenance, the bearing in be satisfied basically and solving equipment to maintain assembles a problem. But the temperature cost that these 2 kinds of methods increase acreage of the be heated in lukewarm process to making sure bearing is in is even, decide very hard. Heating because of traditional acetylene oxygen is mouth of fire of simple energy of life, and adding lukewarm process is only by experience, be added lukewarm bearing temperature is added to how many degrees appropriate master very hard. Temperature is exorbitant, can produce anneal to bearing, reduce the mechanical performance of bearing; Temperature is too low, heat expands the value is insufficient, be hard to assemble. Repair in equipment in, repairman sometimes because be added to bearing lukewarm insufficient, bearing outfit is less than correct locally, be forced to take reshipment act against one's will, increased labor strength thereby. For this, we put forward tradition of a kind of change to be added to bearing especially lukewarm the new method that assemble. 1.

Add with report lukewarm replace acetylene oxygen to add lukewarm. flat hot plate the design is made cylindrical electric stove, entitle bearing report is added lukewarm implement, if pursue,1 is shown. The bearing report that can design different power and norms according to different bearing internal diameter is added lukewarm implement (optimal suitable scope is in above of 300mm/ of φ of bearing internal diameter) . This kind adds lukewarm device to be like next advantages: Hot shoot even, stability, be added lukewarm bearing surface does not have soot, clean, clean, facilitate measure and control bearing temperature. 1.

Use infra-red measure Wen Yi surface of lukewarm to be being added bearing undertakes temperature monitor. Bearing assembles add lukewarm value to be controlled commonly in 100 ℃ ～ 120 ℃ are advisable. Inside this temperature value, heat of bearing rolled steel expands the value is the greatest, facilitating bearing is assembled, this temperature value won't change the mechanical property of bearing again, and reliability is high. The place on put together is narrated, bearing report is added lukewarm implement the acetylene oxygen of excel tradition is added lukewarm, it is to raise bearing to assemble the precision and work efficiency, effective method that reduces labor intensity.
