    齿条加工对原材料的硬度有什么要求?

    来源:http://www.jnzkjx.cn/ 日期:2020-05-21 发布人:kaizejixie
      过加工,首要要对钢材款式进行分析,应为非标齿条根部受应力会集,所以淬火的后查看齿根基地,该处也要到达请求。齿条齿部外表进行查验,不能有过烧呈现,看齿部是否有裂纹,关于小批量的应悉数查看,大批量的应依照规则依照必定的比例进行查看;还要查看齿条外表硬度,通常请求硬度为45~50HRC,承载才能较大的齿条硬度应为50~55HRC。关于齿条的有用硬化层深度,要用维氏硬度计,在齿宽中部齿的截面上,自表至里检查硬度,硬化层硬度值依照以下规则,临界硬度(HVHL)=0.80*规划规则的外表硬度。
      After processing, the steel style should be analyzed first. It should be the stress concentration at the root of non-standard rack, so after quenching, check the root base, which should also reach the request. The appearance of the rack tooth shall be checked to see if there is any over burning. The small batch shall be checked to see if there is any crack. The large batch shall be checked according to the rules in accordance with a certain proportion. The hardness of the rack appearance shall also be checked. Generally, the hardness of the rack shall be 45~50HRC, and the hardness of the rack with large bearing capacity shall be 50~55HRC. As for the useful hardened layer depth of rack, the Vickers hardness tester shall be used to check the hardness from the surface to the inside on the section of the middle part of the tooth width. The key hardness value of hardened layer shall be in accordance with the following rules, and the critical hardness (hvhl) = 0.80 * the minimum surface hardness of planning rules.
      加工啥商品,质量很主要,要想质量好就要有好的原料,非标齿条加工也不破例,齿轮加工对原料硬度有什么具体要求?
      What kind of products are processed, the quality is very important. If you want to have good quality, you need good raw materials. There is no exception for non-standard rack processing. What are the specific requirements for the hardness of raw materials for gear processing?

      1、硬齿面齿轮350HB而言。共轭齿轮的硬度合作同软齿面齿轮一样;
      1. For 350hb hardened gear. The hardness cooperation of conjugate gear is the same as that of soft tooth surface gear;
      2、直齿轮中小齿轮的更小硬度应比共轭大齿轮的硬度高20一25HB就斜齿或人字齿轮而言,软齿面齿轮。非标齿条小齿轮的更小硬度应比共轭大齿轮的硬度高40-50HB;
      2. The minimum hardness of spur gears is 20-25hb higher than that of conjugate gears. For helical or herringbone gears, soft tooth surface gears. The minimum hardness of non-standard rack and pinion should be 40-50hb higher than that of conjugate big gear;
      3、假如非标齿条小齿轮选用表面淬火处理,3软—硬齿面合作而言。则大齿轮能够来用渗氮、渗碳等处理,以汽轮机减速器为例,自动齿轮轴的硬度为285320HB被动齿轮的硬度为245285HB。
      3. If the non-standard rack and pinion is treated by surface quenching, the 3 soft hard surfaces should be used together. For example, the hardness of the automatic gear shaft is 285320hb, and that of the passive gear is 245285hb.
