Pag-aplikar sa kanunay nga puwersa sa tingpamulak sa kaugalingon nga timbang nga balanse nga mekanismo sa sampling device

tinubdan:Katukma sa Qianye panahon:2022-9-14

At present, various sample probes and reagent probes are used in medical laboratory equipment to suck samples, add samples, suck and test u, add reagents, measure and other operations. Most of the devices used in these action combinations are intelligent sampling devices, and the system used can automatically process data. Due to the full function and complex mechanism of the sampling device, the self weight of the system device is large, This brings higher and higher performance and power requirements to the driving motors of various sampling devices.

The self weight balance mechanism is set between the sampling device and the main structure and is composed of a lifting device and a kanunay nga pwersa sa tingpamulak. The lifting device is composed of gears, racks and linear guide rails. The gears are driven by the motor and fixed on the main structure with the motor. The rack and the gear mesh to move up and down. The rack is fixed on the linear guide rail and the sampling device is fixed on the rack, The lifting device can also be composed of gear combination roller chain or synchronous belt, ball screw or flexible rope.

The upper end of the kanunay nga pwersa sa tingpamulak is fixed on the main structure, and the lower end of the kanunay nga pwersa sa tingpamulak is wound on a roll shaft on the sampling device. The roll shaft can rotate with the rise and fall of the sampling device. According to the height of the rise and fall of the sampling device, the excess part of the kanunay nga pwersa sa tingpamulak can always be wound on the roll shaft. No matter how long the kanunay nga pwersa sa tingpamulak is stretched, its own force wound on the roll shaft is constant, and the tension of the kanunay nga pwersa sa tingpamulak is greater than or equal to the rack The sum of the gravity of the linear guide rail and the sampling device.

Kanunay nga pwersa sa tingpamulak is made of steel strip. When it is straightened by external force, the spring will naturally roll back and produce elastic force. The advantages of constant force spring over traditional wire spring are as follows:

1.High elastic output can be achieved in a very small device space.

2.Maintain a certain elasticity in all strokes. The preload stroke is short, that is, the required elasticity can be achieved through a short stroke. The original long-term is smaller than the line spring, and the stroke is unlimited.

When designing or specifying a kanunay nga pwersa sa tingpamulak, many basic engineering parameters need to be considered. Material, fatigue life, tensile load, torque and friction, speed and acceleration, installation, safety considerations and application environment are all key factors.
