On the basis of this result further study is made on thermal elastic deformation resulted from bulk temperatures changing and transmission load of the spurs gear in the direction of tooth and axle.
在应用边界元方法计算直齿圆柱齿轮的本体温度场的基础上,进一步研究了直齿轮在齿厚方向和沿其轴向由其本体温度的改变和传动载荷而引起的热弹性变形。
Sometimes lower die temperatures can create a cool layer of resin on the inner surface of the die that creeps slowly to the die exit and then separates from the bulk flow, causing buildup.
有时,较低的口模温度会在口模内表面上生成一个冷却的树脂层,这个树脂层慢慢地移出到口模出口,然后与本体料流分离,从而引起积料。
The effects of different temperatures on compressive strength and bulk density were studied.
