如何正确选择滚珠丝杆支撑座呢?

来源:http://www.jngongrun.com/ 日期:2020-10-15 发布人:admin

伴随着工业改革机制,自动化机械手厂家越来越多,则需要丝杆支撑座部件的也就越多,目前市场上的型号各式各样,千奇百态,有研磨、有冷轧,如何区分,选择合适自己的呢? 我们来听一下技术人员的分析,那么如何正确选择滚珠丝杆支撑座呢?

With the industrial reform mechanism, there are more and more automatic manipulator manufacturers, and more and more screw rod support seat components are needed. At present, there are various types of models on the market, including grinding and cold rolling. How to distinguish and choose the appropriate one? Let's listen to the technical personnel's analysis, then how to correctly select the ball screw support seat?
一、我们要清楚标准型滚珠丝杆支撑座的规格定义,通常丝杆轴承座产品代号,可分为固定座AK、BK、EK、FK,支撑座AF、BF、EF、FF等八种型式。
1、 We should make clear the specification and definition of the standard ball screw support seat. Generally, the product code of screw rod bearing seat can be divided into eight types: fixed seat AK, BK, EK, FK, and support seat AF, BF, EF, FF.
轴承座公称轴径,为固定端轴承座的内径,为两码数字,单位为mm,例如30为内径30mm;35为内径35mm;支撑端轴承座的公称轴径是指相对应固定端轴承的公称轴径,支撑端轴承座的轴承内径等于或小于公称轴径。
The nominal shaft diameter of the bearing block is the inner diameter of the fixed end bearing block, which is a two yard number, and the unit is mm. For example, 30 is the inner diameter of 30mm; 35 is the inner diameter of 35mm; the nominal shaft diameter of the support end bearing block refers to the nominal shaft diameter of the corresponding fixed end bearing, and the bearing inner diameter of the bearing support end is equal to or less than the nominal shaft diameter.

二、轴承形式,空白表示为标准规格,一般系使用30°接触角轴承(A型),但公称轴径35及40的规格因为较高轴向负荷需求,特别使用40°接触角轴承;B为40°接触角轴承;但只有公称轴径20mm(含)以上的规格才有40°接触角轴承的设计。
2、 Bearing form, blank is expressed as standard specification. Generally, 30 ° contact angle bearing (type A) is used, but 40 ° contact angle bearing is specially used for specifications with nominal shaft diameter of 35 and 40 due to higher axial load demand; B is 40 ° contact angle bearing; however, 40 ° contact angle bearing is only designed for specifications with nominal shaft diameter of more than 20 mm (including).
三、C3:轴承座等级,分为C3、C5、C7三种级数。建议C3级丝杆选用C级轴承座,C5级丝杆选用C5级或C3级轴承座,以使轴承座的精度可以和丝杆的精度匹配;而C7级丝杆建议只需选用C7级轴承座即可。
3、 C3: bearing pedestal grade, divided into C3, C5 and C7. It is suggested that grade C bearing block should be used for C3 screw rod, C5 or C3 bearing seat should be selected for C5 screw rod, so that the accuracy of bearing seat can match with that of screw rod; and C7 screw rod only needs C7 bearing seat.
四、表面处理,分为染黑和表面镀镍两种,标准品为染黑处理,不标记表面处理符号;而表面镀镍处理者,表面处理符号标记为N,但表面镀镍者无库存,采取2订单式生产。
4、 The surface treatment is divided into two types: black staining and nickel plating. The standard product is dyed black, and the surface treatment symbol is not marked; while for the surface nickel plating treatment, the surface treatment symbol is marked as N, but the surface nickel plating person has no stock, and adopts 2-order production.
听了上述我们工程师的分析,相信各位在对丝杆轴承座选型的时候,都知道该怎么区分和对应了,当然在实际运作中,有哪些不清楚的地方,可以关注公司网站:http://www.jngongrun.com
After listening to the above analysis of our engineers, I believe that you all know how to distinguish and correspond when selecting the type of screw rod bearing pedestal. Of course, in actual operation, if there are any unclear points, please pay attention to the company's website: http://www.jngongrun.com 。
