丝杠预紧的目的是为了什么?

What is the purpose of lead screw preloading?
用油脂润滑时,是非常易粘附在螺旋滚道外表,坚持的润滑情况。让其在作业的时分,可以有用减少运动部件的磨损及解决噪音问题,具有的抗磨抗压才华及高低温功用安稳。虽然留意滚珠丝杠副保涂层中不会出现碎屑和空位,但要小现已证明空位对系统功用没有影响。
When lubricating with grease, it is very easy to adhere to the surface of the spiral raceway and adhere to the lubrication. During operation, it can effectively reduce the wear of moving parts and solve the noise problem. It has the ability of anti-wear and compression and the function of high and low temperature. Although it is noted that there will be no debris and vacancy in the protective coating of the ball screw pair, it should be small. It has been proved that the vacancy has no effect on the function of the system.
转移只要螺母,滚珠丝杠螺母就可以在整个组件的运用寿数期间继续运转定期穿过涂层区域。滑剂,虽然是固体,在流体剂中也具有一些“扩散”才华。涂层螺丝供应大度的自滑,不该额定滑或在或许存在油或其他润滑剂污染的环境中运用。钢制螺丝由合金钢制成,通过热处理后具有很高的抗拉强度。
As long as the nut is transferred, the ball screw nut can continue to operate throughout the service life of the assembly and pass through the coating area regularly. Slip agent, although solid, also has some "diffusion" talent in fluid agent. Coated screws provide generous self slip and should not be rated for slip or used in environments that may be contaminated with oil or other lubricants. Steel screws are made of alloy steel and have high tensile strength after heat treatment.

不锈钢内六角螺钉一般由302或304制成,不进行热处理。螺钉有多种类型。这些螺钉的规划材料和螺纹类型根据其用途和预期联接在一同的材料而有所不同。机器螺钉是常见和通用类型的螺钉,规划有直的,非锥形的柄和钝端。钣金螺钉,也称为自攻螺钉,用于功用和规划。根据金属的需求,它们的头部可所以扁平,椭圆形或六角形。
Stainless steel hexagon socket screws are generally made of 302 or 304 without heat treatment. There are many types of screws. The planned material and thread type of these screws vary according to their purpose and the material expected to be connected together. Machine screw is a common and universal type of screw with straight, non conical shank and blunt end. Sheet metal screws, also known as self tapping screws, are used for function and planning. According to the demand of metal, their heads can be flat, oval or hexagonal.

可是如何在不牺行程长度的情况下减少滚珠丝杠的无支撑长度?长途旅行与高速:你可以有两者滚珠丝杠支撑可以处理这种长度速度的窘境。这些浮动支撑(一般用于2,4或6组)位于滚珠螺母的一侧,并以容许它们在滚珠丝杠螺母的一侧延伸到持平间隔的办法联接,如螺母沿相反方向移动,按比例减小无支撑长度。
But how to reduce the unsupported length of the ball screw without sacrificing the stroke length? Long distance travel and high speed: you can have two ball screw supports to deal with the dilemma of length and speed. These floating supports (generally used for groups 2, 4 or 6) are located on one side of the ball nut and connected by allowing them to extend to a flat interval on one side of the ball screw nut. If the nut moves in the opposite direction, the unsupported length is reduced proportionally.
在滚珠螺母跋涉的方向上,支撑件在螺钉的结尾堆叠以供应对行程的小搅扰。根据临界速度方程,添加一组滚珠丝杠支撑(滚珠螺母两边各一个支撑)将使螺杆的临界速高四!金属制造和木匠中的切开,布线和其他操作是常见的运用用于滚珠丝杠支撑,由于它们需求高推力和的定位精度,一同速移动长间隔。
In the direction of travel of the ball nut, the supports are stacked at the end of the screw to provide small disturbance to the stroke. According to the critical speed equation, adding a set of ball screw supports (one support on both sides of the ball nut) will increase the critical speed of the screw by four! Cutting, wiring and other operations are common in metal manufacturing and carpentry. They are used for ball screw support. Because they require high thrust and positioning accuracy, they move at the same speed for long intervals.
除了自润滑缩醛螺母材料,供应种定制复合Ke复合聚合物。聚合物是一种高材料系列,具有色的磨性和本钱通过注塑成型供应规划势。聚合物供应种各样的机械,热和电功用,并与许多化学品兼容环境条件。合聚合物是大多数螺母的选择导轨和轴衬套,的标准材料衬套和端部支撑
In addition to self-lubricating acetal nut materials, a custom composite Ke composite polymer is supplied. Polymer is a kind of high material series with color abrasiveness and cost. It is supplied through injection molding. Polymers supply a wide variety of mechanical, thermal and electrical functions and are compatible with many chemicals and environmental conditions. Synthetic polymer is the choice for most nuts, guide rail and shaft bushing, standard material bushing and end support
