怎么样可以提高滚珠丝杆的性能?

永利总站/ 日期:2019-01-18 发布人:admin

机床中比较重要的零件就是滚珠丝杆了,直接影响到机床的功用。而现在又是一个考究一个高效率的年代,对机床就有更高的要求。想要机床功用更好,就需要有功用更好的滚珠丝杆,那要怎样才干前进滚珠丝杆的功用?

Ball screw is one of the most important parts in machine tools, which directly affects the function of machine tools. Now it is an era of high efficiency, and there are higher requirements for machine tools. If you want the machine tool to function better, you need a ball screw with better function. How can you advance the function of ball screw?
1.恰当加大螺杆的转速,导程和螺纹头数
1. Increase properly the speed, lead and number of threaded heads of the screw
现在常用大导程滚珠丝杆名义直径与导程的匹配为:40*20,50*25等,其进给速度均可达到60m/min以上。为前进滚珠丝杆的刚度和承载才干,大导程滚珠丝杆一般选用双头螺纹,以前进滚珠的有用承载圈数。
Nowadays, the matching of nominal diameter and lead of ball screw with large lead is 40*20, 50*25 and so on. Its feed speed can reach more than 60 m/min. In order to improve the stiffness and carrying capacity of the forward ball screw, the large lead ball screw usually adopts double thread, and the number of useful bearing circles of the forward ball screw.
2.改进结构,前进滚珠运动的流畅性
2. Improving the structure and smoothness of forward ball movement
改进滚珠循环反向设备,优化回珠槽的曲线参数,选用三维造型的滚珠管和回珠器,实在做到沿着内螺纹的导程角方向将滚珠引进螺母体内,使滚珠运动的方向与滚道相切而不是相交。这样可把冲击损耗和噪声减至较小。
Improve the reverse equipment of ball circulation, optimize the curve parameters of ball return groove, and select three-dimensional modeling ball tube and ball return device, so that the ball can be introduced into the nut body along the guide angle direction of the internal thread, so that the direction of ball movement is tangent to the raceway rather than intersecting. In this way, the impact loss and noise can be minimized.
3.选用“空心强冷”技术
3. Selection of "Hollow Strong Cooling" Technology
高速滚珠丝杆在运行时由于冲突发作高温,构成螺杆的热变形,直接影响高速机床的加工精度。选用“空心强冷”技术,就是将恒温切削液通入空心丝杠的孔中,对滚珠丝杆进行强制冷却,坚持滚珠副温度的稳定。这个办法是前进中,大型滚珠丝杆高速功用和作业精度的有用途径。
The thermal deformation of high-speed ball screw, which is caused by high temperature due to conflict, directly affects the processing accuracy of high-speed machine tools. Choosing "hollow strong cooling" technology is to put constant temperature cutting fluid into hollow screw holes, force cooling the ball screw, and adhere to the stability of the temperature of the ball pair. This method is a useful way to advance the high speed function and operation accuracy of large ball screw.
4.滚珠丝杆支撑轴承的选择
4. Selection of ball screw bearing
关于滚珠丝杆轴承的选择至关重要,它直接影响到雕刻机等机床设备或主轴的寿数和功用。
The selection of ball screw bearings is very important, which directly affects the life and function of machine tools such as engraving machines or spindles.
