机械类 (中译英): 蜗杆减速机使用前应注入N220~N320(环境温度-30℃~40℃)或N320~N460(环境温度40℃~65℃)润滑油至油标中心点之上,并取掉通气器上之小锥塞。首次使用100小时后,洗净内部换上新油,以后每2500小时换油一次。 设备是利用电热能对产品进行加热。设备内部为高温状态,设备表面局部温度较高。请务必带手套,着长袖作业服进行操作,否则有烫伤的危险。
优点:主要应用于轧机及重型机械里的传动部分; 由一非常结实的夹布橡胶制夹紧部和一与其紧密结台在一起的橡胶密封唇部组成; 拉伸弹簧增加密封唇口对旋转轴的径向压紧力; SR2型应用于需要提供额外润滑的场合,这时,密封圈需背靠背安装,通过 密封槽同边的环行槽及密封圈上的径向槽,把润滑剂加在两密封圈之间。

Part 1: Translate Chinese into English For worm reducer, before it will be used, the lubricating oil, such as N220~N230(for environment temperature between 30 Celsius degree below zero and 40 Celsius degree) or N320~N 460(for environment temperature between 40 Celsius degree and 65 Celsius degree), should be poured up to the center point of the oil level gauge, and the small cone-shaped plug upon the air door (on the top of the reducer cover) should be removed. The inner part of the reducer should be washed and cleaned, and the lubricating oil mentioned above should be replaced when the reducer has been worked for the first 100 hours, and then the lubricating oil will be replaced for each another 2 500 hours of work. This equipment heats the production by means of electric power. The interior of this facility is in high temperature, and the local temperature on the outer surface is quite high. The glove, work clothes with long sleeves must be equipped when the workers want to operate the machine, otherwise it will be dangerous, and scald hurt will be happened.
Advantages: It is mainly used as the transmission of rolling machine and heavy machineries; It consists of a clamp which is made of rubber with cloth in and a rubber airproof lip which is closed connected with the clamp; The pull spring enhances the radial press force between the airproof lip and the rotary shaft; Type of SR2 will be used in the case where the extra lubricating is required, here the airproof ring will be installed back to back, and the lubricating oil will flow along the round groove which is in the same side with the airproof groove and the radial groove of airproof ring, and it will be filled into the inner space between the two airproof rings.
