胎面的選擇

PU輪 (聚胺酯輪)

醫療和工業輪等各式腳輪,胎皮表面多以聚胺酯 (PU) 製成。這是因為PU高強度耐磨的材質特性以及良好的承載能力。

為提供最滑順與靜音的輪子與使用者,聖佰堅持採用高品質的台灣生產PU原料,讓輪子在推行之時達到省力的目的、以及地板完全不會有摩擦的痕跡、並且耐重。在使用壽命上也比一般製造商的品質來的更耐久!

但PU不耐水性是其先天缺點,因此在受到潮溼環境以及醫院的化學清潔劑和高溫消毒作業等等,並不推薦。除此之外,PU輪的表面會隨著長時間曝露在低溫環境 (攝氏0度以下) 的影響,導致PU輪胎表面因逐漸硬化。

 

TPR輪 (塑性橡膠輪)

塑性橡膠 (TPR) 是另一種廣泛地使用在輪子表面的材質,包含醫療輪以及工業輪。TPR主要的優勢是它的高彈性特質,可以吸收移動時因碰撞而產生的震動。因此,TPR輪適合用於醫療設備上。

若本身的產品不常推動,並於高承載下,TPR胎面可能變形,會影響輪子推動的性能。

 

尼龍輪

尼龍是一種硬度很高的材質。因此,他的承載最佳,使用壽命也長,所以常常被拿來使用做工業腳輪。然而,也由於它的高硬度,導致當尼龍輪在移動時,會產生較大的噪音。因此多使用在工業環境。

 

導電輪

導電輪主要被使用在高階的醫療設備以及高科技工業。不論是PU或TPR導電輪,我們生產的皆符合國際標準的規定 (電阻小於104 Ω)。導電輪適用於需要經常移動的精密電子設備,例如醫療儀器,推車,或病床等等。主要的功效,在於可將電力自醫療儀器引導至地面,以確保病患以及設備的安全。

 

抗靜電輪

PU和TPR皆可製為導電輪,並符合國際標準的規定(電阻小於108 Ω)。一般而言,靜電主要是在乾燥的環境下移動所產生的。因此,地板上的灰塵與毛髮等等,都會因此而吸附在輪子的表面上,久了就會影響輪子運行的效能。然而抗靜電輪,正是解決此問題的最佳方案。

 

Bearing Selection


Roller bearings
Roller – raceway contact is theoretically linear.

Furthermore, there are several different types of rollers:


Ball bearings
Theoretically, ball – raceway contact is limited to occasional.
Ball bearings are the most widely used in industry because they feature the best performance / price ratio.
They are found in wheels, car transmissions, farming machinery, machine tool spindles, etc.

If the gap clearance is increased, angular contact is obtained; the bearing can now bear increased axial loads* and performance levels are enhanced.

Cylindrical
Cylindrical roller bearings are used in car gearboxes, on bearing block 4 of the Boeing and Airbus CFM56 engine, in the rail sector. The cylindrical bearing is almost always used with a ball bearing to support axial loads.


Taper
The advantage of the taper roller bearing is that it can withstand combined loads*, while it has a very small outside dimension footprint. It is notably used in car wheels, train sparkplugs etc.
However, the drawback is that it is difficult to manufacture and is therefore more expensive.


Spherical
Contact pressure between rolling bodies and raceway is distributed along a line in roller bearings. In ball bearings, it is concentrated on a single point. It is for this reason that, for comparable outside dimension footprint, roller bearings withstand higher loads* and lower limit speeds.
