第827章 铜轴承(1 / 2)

加入书签 | 推荐本书 | 问题反馈 |

近日,李泰与将作大匠研究轴承有重大突破。

几经试验,从玻璃轴承转型成铜铸轴承。其承重耐损程度用在打谷机上完全没问题。

不过却难以普及,价格太贵。

“偏心力有些大啊,铜珠精度还需打磨!”

临近黄昏时分,苏尘与李泰以及五名皇宫调来工金银器匠人,安装好打谷机测试刚研发出轴承。

铜铸轴承个头很大直径约寸半,重约七两耗费铜钱九十三文。

开元铜钱积十文一两,由此可见熔炼铜钱制作轴承火耗很大。

据李泰所言,目前用来铸造轴承的铜钱已达六千枚。

内环、外圈由将作监大匠以型砂铸造一体成型,外表无焊接缝滚道细致打磨平滑。

偏心力大,打谷机滚桶稍见上下跳动现象,原因在于轴承铜珠不达标。

制作过程中,匠人们发现越小的铜珠更难掌握成圆,事后打磨亦是不好下手。

与以往制作金银器物、首饰完全不同。

五名将作大匠听得苏尘感叹之言,立即作揖赔礼致歉。“侯爷见谅,我等技艺不精,有负侯爷与殿下所望!”

“各位大师言重了!”苏尘站直身体,跟着作揖一礼:“时间不足一个月,各位师傅能将轴承做到这般程度,实为难得!”

匠人再次对苏尘、李泰一礼,“多谢侯爷体谅!请侯爷与殿下放心,我等定将悔思前车之鉴力求轴承铜珠大小合一!”

“哈哈哈,各位师傅手艺精湛肯定能做的!”苏尘哈哈一笑,继而提醒道:“不用担心浪费铜钱,现在我们主要是掌握和熟悉轴承的制作方法。

铜做的轴承不耐磨损,将来轴承是用材质更为坚硬的钢铁制成。”

五人再次向苏尘拜道:“我等谨记侯爷之言!”

“呵呵!”苏尘拱手回礼,转身走向一旁炭火炉上酒坛一半大小的坩埚。

坩埚,用来熔炼金银铜化汁的耐火器皿,后来称为坩锅。

“参见公主殿下!”

前来寻找苏尘的长乐公主点头回应,径直走向苏尘与李泰。

苏尘整个下午不曾回到庄园大殿,在村子里待了一个多小时,与村民说了一直明天皇帝要来犁地。

又去了玻璃作坊和军工厂,之后便是李德謇负责的温室大棚,最后来到李泰这边。

“敢问公主殿下来此有何贵干?”听到长乐公主靠近的脚步声,苏尘拱手问道。

眼睛却没有看向长乐公主。

长乐公主双手分别搭在苏尘与李泰肩膀上,“酉时一刻,侯爷该用膳了!”

“哦!”苏尘看了一下手表,走到几位金银器匠人跟前,拱手一礼,“各位师傅,时间已不早今天先这样吧!”

“我先回去了哈!”

五名匠人面带微笑,拱手相送。

夕阳下,苏尘三人并肩走向庄园主殿。

长乐公主走在两人中间,时不时给两人后背来一下,李泰几次欲先行离开却被长乐公主拽住。

苏尘向李泰使一眼色,后者会意一笑。

“啊~!”

“大胆,速速放开本小姐!”

苏尘与李泰一人架着长乐公主一只胳膊,将她双脚离地提着往前走。

任由长乐公主双脚乱蹬,两人皆不搭理架着她继续前行。

“两位好汉行行好,放过本小姐吧!”威胁不成,长乐公主可怜兮兮求饶。

苏尘与李泰相视一眼,将长乐公主放下。

长乐公主甩了甩胳膊,就要向两人后背招呼,“好哇!敢如何对待本小姐,看招!”
