热双金属片温控开关涉及一种汽车上使用的控制发动机冷却风扇起动和关闭的温控开关.它由壳体、导向座、双金属片、挺杆和簧片与接线柱构成的开关组成,双金属片的形状是一个比圆形面积小的对称形状,如三角形、方形.这种形状的双金属片克服了圆形金属片上下转变温度差大的缺点
X线机遥控装置传动部分的改进是针对荧光屏移动和胃肠压迫器的传动而设计的,在荧光屏移动传动中,于机架上设计一长条状链条,随着电机转动带动荧光屏沿链条作相对移动；胃肠压迫器的摆动是靠电机带动凸轮,拨动两个半凹轮使其相互咬合,互相换位来实现.该装置因采用交流减速可逆电机不需要整流和减速,具有体积小,重量轻,力矩大等优点.此外,这种传动装置结构简单、移动稳定可靠,无噪音且使用寿命长.

The hot bimetal piece controls the switch to involve the control engine cooling ventilator starting which and the closure warm on one kind of automobile uses controls the switch warm. It the switch which by the shell, the guidance place, the bimetal piece, the tappet and the reed and the wiring column constitutes composes, the bimetal piece's shape is one compared to the circular area small symmetric figure, like triangle, square shape. This kind of shape's bimetal piece has overcome circular tinsel high and low transformation temperature difference big shortcoming
X machine remote monitor transmission part's improvement is aims at the fluorescent screen migration and the stomach and intestines compressor's transmission designs, in the fluorescent screen moves in the transmission, designs a strip-shaped chain link on the rack, drives the fluorescent screen along with the electrical machinery rotation along the chain conditional relative migration; Stomach and intestines compressor's swinging is leads the cam depending on the electrical machinery, moves two-and-a-half concave wheels to cause its mutual linking, the conversion realizes mutually. Because this equipment uses the exchange to decelerate the reversible electrical machinery not to need the rectification and the deceleration, has the volume to be small, the weight is light, moment of force big and so on merits. In addition, this transmission device structure is simple, migration stable reliable, does not have the noise, and the service life is long.
