1.对已经淬火的钢件再次加热的热处理叫做退火。 2.滚动轴承的寿命与额定动载荷成正比,与轴承的计算载荷成反比。 3.润滑油的倾点比凝点高。 4.斜齿轮的缺点是有轴向力。 5.过盈是按照过盈配合孔的最大极限尺寸与最小极限尺寸计算的。 6.以30m/min的速度提升1t重的物体,所需的电动机功率约5kW。
1. The quenched steel is heated again after the heat treatment is called annealing. 2. Rolling bearing life is proportional to the rated dynamic load, and the bearing load is inversely proportional to the calculation. 3. The pour point of lubricating oil is higher than freezing point. 4. The disadvantage of helical gear is the axial force. 5. The interference is calculated in accordance with the maximum limit of interference fit hole size and the minimum limit size. 6. The 1t heavy object is lifted at a speed of 30m / min, and the required motor power is about 5kW.
