【摘要】：设计了一种轴承加热控制器,采用PIC单片机作为核心控制器件,为了实现理想的退磁效果,通过控制单向可控硅的导通角逐渐减小加热电路中的电流;同时设计两路热电偶检测电路,用于对大尺寸轴承加热时分别检测轴承的内环和外环温度,这样做的好处是可避免轴承因受热不均时造成的内外温差大,内外环膨胀不一致,滚珠挤压滚道,产生应力集中,引起轴承变形。另外,在外围电路的配合下,有效提高了控制器的精度和使用寿命。经过测试验证,该控制器加热温度准确,并有较好的退磁效果,达到了预期的效果。
[Abstract]:A kind of bearing heating controller is designed in which PIC single chip microcomputer is used as the core controller. In order to realize the ideal demagnetization effect, the current in the heating circuit is gradually reduced by controlling the conduction angle of the unidirectional thyristor. At the same time, two thermocouple detection circuits are designed to detect the temperature of the inner ring and the outer ring of the bearing respectively when the large size bearing is heated. The advantage of this method is to avoid the large temperature difference between the inner and outer rings caused by the uneven heating of the bearing. The inner and outer ring expansion is inconsistent, the ball extrudes the raceway, produces the stress concentration, causes the bearing deformation. In addition, under the peripheral circuit cooperation, effectively improves the controller precision and the service life. The controller has accurate heating temperature and good demagnetization effect.

【正文快照】： 0前言轴承是通过滚珠来实现机械支撑,承载摩擦的,它的损坏几率比普通机械零件要大的多。轴承在安装时,不可用力锤击,为避免造成轴承损坏,通常采用的办法是加热[1],加热到轴承能够容易安装时的温度。有经验的工作人员可根据经验设定合适温度值。通常将轴承加热到100℃~120℃范
