Castor structure and the selection of medical equipment
Medical apparatus and instruments castor structure and use of castor parts including the bushing, double bearings, charged support components, rivets and the single theory in the middle. Details as follows: liner: liner is made of steel rolling parts, placed outside the shaft. Outside the axle, a steel of rolling piece to wheel bearing, so that the fixed scroll wheel to the scaffold. The sleeve has a rolling shaft. 2, rolling bearing: there are several different types of steering bearings, such as single bearing: large orbit is only a layer of steel ball, often referred to as single row ball bearing. Double bearing: also known as double row bearings, in two different orbit has a double ball. Economic bearing: composed by one supported by stamping on the flange of steel ball. Precision bearing: the standard industrial bearing manufacturing. 3. On-site support assembly: charged branch components by mobile scaffold, shaft and the nut. Do not include the wheel, wheel hub bearing and bushing. Among among 4, rivet, rivet is a component of the floor, for the rolling device of fixed bolts or rivets. Screw down the bolt type rivet to adjust loose caused by roll wear. Before buying, must understand the choice of the caster wheel bearing. Castor has a variety of bearings. Without it, castor will lose value. Therefore, we advocate the ambitions of the bearing should be suitable for their respective applications, and to ensure that the necessary safety margin left. In addition to the surface of the wheel, wheel diameter and rotating bearing, wheel bearing also determines the mobility of the caster and the quality of the caster. For different operating environment have different requirements: casters used in the factory the casters used in different commercial plant. Tool used in the caster and hospital bed using different light castor. Demand for shopping cart caster wheel must be with those who used to transport heavy objects in these factories castor is completely different. In general, there are four types of bearings: 1, Tel Ling bearing: Teling is a kind of special engineering plastics, suitable for humid and corrosive local, usually transformation, the sensitivity of the resistance is bigger. 2. Roller bearings: after heat treatment of roller bearings can bear heavier load and change the sensitivity. 3. Ball bearing: USES the high quality of bearing steel ball bearings can withstand overload, apply to the change of demand, the quiet places. 4, surface bearing: applicable to high, high load and high speed.
