Abstract
The utility model discloses a helix insertion pipe for a rolling linear guide rail pair. The helix insertion pipe comprises a pipe body manufactured by compounding engineering plastic, wherein the section of the pipe body is circular; and a helix groove is formed on an inner hole wall of the pipe body. The helix insertion pipe is preliminarily formed by an injection molding process, and a finished product is obtained by performing cold machining on a helix. The insertion pipe in the conventional rolling guide rail pair in the market is innovated, so that a rolling body can stably run along the own axis when running at high speed due to the action of gyroscopic moment, and the usability of the rolling guide rail pair is ensured. The helix insertion pipe has a simple structure and a comprehensive effect, is low in cost, reduces the vibration of the rolling body of the rolling guide rail pair and noise, and is high in dynamic noise.
Description
Technical field
The utility model relates to the linear rolling guide parts, specifically is a kind of intubate that is used in linear rolling guide slide block and the back device.
Background technique
Linear rolling guide generally is made up of guide rail, slide block, rolling element, back device etc.; Circulating rolling is realized the straight line motion of rolling guide-rail pairs in the raceway that between guide rail and slide block, forms through rolling element; Be accurate rolling function parts, be widely used in the numerical control machine tool industry.Because the approximate straight line of the track of linear rolling guide in load path; And turning in the path in two end cap; Rolling element need have very big moving direction to change, and when movement locus produced the change on the curvature, the speed of rolling element had slightly and changes; Speed difference between each rolling element causes between adjacent rolling element and pushes.Existing rolling linear guide, the material multiselect metal species of its rolling element, when the rolling element rapid change, rolling element bumps and pushes friction, the noise and the vibration that produce linear rolling guide each other.In addition, when rolling element rolled in load path, because the moving direction of adjacent rolling element on point of contact is different, stressed each other and friction also can cause the increase of noise and frictional resistance.Though have preferable material (for example ceramics material) to be used in recent years, the quality of its rolling element is less, collision energy is lower; And hardness is high; Advantages such as the good and damping property of wear resistance performance is good, however prices are rather stiff, and the rolling guide that general industry is used can not be accepted its fancy price.For reducing noise, people have expected in rolling guide-rail pairs, increasing plastic cannula, but when the rolling guide-rail pairs high speed operation, the irregular collision of rolling element in stream ball hole still can produce bigger vibrations and noise.
The model utility content
The purpose of utility model patent is: provide a kind of when the rolling guide-rail pairs high speed operation, make the helix intubate of rolling physical efficiency along self axis stable operation, the vibrations and the noise that produce when effectively reducing the irregular collision of rolling element.
The technological scheme that the utility model adopts is: a kind of linear rolling guide is used the helix intubate, comprises the body of being processed by engineering plastics, and the body cross section is circular, and the inner hole wall of body has helix groove.
The beneficial effect of the utility model is: the body of intubate is selected engineering plastics for use, and pliability is good, realizes difform rolling element tracks such as arc, straight line easily, and the orbital position degree guarantees that easily dimensional accuracy improves.The inner hole wall of helix intubate has helix groove, when the rolling element high speed operation, because the effect of gyrostatic moment; Make of the axis stable operation of rolling physical efficiency along self; Thereby the irregular collision between the minimizing rolling element reduces the vibrations of rolling element, effectively reduces the noise that rolling element produces.The utility model is installed in the slide block and back device of rolling guide-rail pairs, and inwall has adopted unique helix groove structure, plays the General of slide block damping, whole noise reduction.

Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Wherein: 1, body; 2, inner hole wall; 3, helix groove.
Embodiment
Below, in conjunction with embodiment, the utility model is further described.
With reference to Fig. 1, a kind of linear rolling guide is used the helix intubate, comprises that the body cross section is circular by the compounded body 1 of engineering plastics, and the inner hole wall 2 of body has helix groove 3.The helix intubate is through the Shooting Technique preliminarily forming, and cold again machining helix is to obtain final finished.The utility model patent is innovated to the intubate in the existing rolling guide-rail pairs in the market; When the rolling element high speed operation; Because the effect of gyrostatic moment, make the rolling physical efficiency along self axis stable operation, to guarantee the usability of rolling guide-rail pairs.The utility model is simple in structure, and is with low cost, and the General that can play is a kind of good technological scheme of moving noise that the shake of rolling guide rolling element reduces noise that reduces.
