齿轮传动是应用极为广泛和特别重要的一种机械传动形式,它可以用来在空间的任意轴之间传递运动和动力,目前齿轮传动装置正逐步向小型化,高速化,低噪声,高可靠性和硬齿面技术方向发展,齿轮传动具有传动平稳可靠,传动效率高(一般可以达到94%以上,精度较高的圆柱齿轮副可以达到99%),传递功率范围广(可以从仪表中齿轮微小功率的传动到大型动力机械几万千瓦功率的传动)速度范围广(齿轮的圆周速度可以从0.1m/s到200m/s或更高,转速可以从1r/min到20000r/min或更高),结构紧凑,维护方便等优点.因此,它在各种机械设备和仪器仪表中被广泛使用.本文设计的就是一种典型的一级圆柱直齿轮减速器的传动装置.其中小齿轮材料为40Cr(调质),硬度约为280HBS,大齿轮材料为45钢(调质),硬度约为240HBS,齿轮精度等级为8级.轴、轴承、键均选用钢质材料.

Gear transmission is widely used and particularly important a mechanical transmission form,it can be used in the space between the arbitrary and power transmission shaft,gear transmission device is gradually to miniaturization,high-speed,low noise,high reliability and hard-toothed surface technology development direction,gear transmission with high efficiency,stable and reliable (usually can reach 94%,precision of cylindrical gears can be reached 99%),transmission power range from the meter (in small power transmission gears to large-scale dynamic mechanical power transmission) tens of thousands kw (gear speed range from 0.1 circumference speed m/s to 200msps or higher,speed can be from Grimm 20000r/min/min to or higher),compact structure,convenient maintenance,etc.Therefore,it is in various mechanical equipment and instrument is widely used.This design is a kind of typical level spur gear reducer transmission device.One small gear materials for 40Cr (conditioning),hardness is about 280HBS,big gear materials for 45 steel (conditioning),hardness and precision of 240HBS approximately 8 rating for the gear.Axial bearing steel materials are chosen and key.
