Abstract

The utility model discloses a self-lubricating damping and noise-reducing intubation tube used for a rolling linear guide rail pair. The self-lubricating damping and noise-reducing intubation tube comprises an inner layer and an outer layer, wherein the inner layer is manufactured by porous natural fiber containing lubricating oil; the outer layer is manufactured by engineering plastics or by compounding the engineering plastics and glass fiber; the cross sections of the inner layer and the outer layer are respectively in a round ring shape; the inner layer and the outer layer are compounded into a whole; a outer pipe manufactured by the engineering plastics is formed by an injection process; a porous layer formed by a rolling process is adopted in an inner pipe manufactured by the natural fiber; the inner pipe is used matched with the outer pipe manufactured by the engineering plastics; and the porous layer contains the lubricating oil which is low-noise lubricating oil. The self-lubricating damping and noise-reducing intubation tube is used matched with a slider in the rolling linear guide rail pair and is placed in a flow ball hole in the slider. The utility model provides new innovation for the traditional control manner of lubricating, damping and noise reducing; the self-lubricating damping and noise-reducing intubation tube is added into the slider of the rolling linear guide rail pair, thereby playing the comprehensive effects of lubricating rolling bodies, damping the slider and entirely reducing the noise.

Description

A kind of selflubricating damping noise reduction intubate that is used for linear rolling guide

Technical field

The utility model relates to linear rolling guide, specifically is a kind of selflubricating damping noise reduction intubate that is used in linear rolling guide slide block and the back device.

Background technique

Linear rolling guide generally is made up of the straight line motion of circulating rolling realization rolling guide-rail pairs in the raceway that between guide rail and slide block, forms through rolling element guide rail, slide block, rolling element, back device etc.; Be accurate rolling function parts, be widely used in numerical control bed 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; Then 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 each other, and the noise and the vibration that produce linear rolling guide.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.

Summary of the invention

The purpose of the utility model is: provide a kind of cost performance high rolling guide-rail pairs intubate, comprehensively solve lubricated, the vibrations of rolling guide by-product, the problem of three aspects of noise.

The technological scheme that the utility model adopts is: a kind of selflubricating damping noise reduction intubate that is used for linear rolling guide; Comprise body; The internal layer that body is processed by the porous natural fibre that contains the lubricant oil hole and form by engineering plastics or engineering plastics and the compounded skin of glass fibre; Internal layer, outer layer cross section are ring, and internal layer is compound with skin to be one.

As preferably, the outer field material of intubate also can select for use 70% ABS engineering plastics and 30% glass fibre to form; The porous natural fibre of the internal layer of intubate can adopt that length of staple is long, the natural fibre of good toughness such as sisal hemp, abaca, ramie or flax; The lubricant oil of internal layer can be with the noise reduction sound lubricating grease of being processed by thickening agent multiviscosisty artificial oil.

The beneficial effect of the utility model is: the skin of intubate is selected engineering plastics or engineering plastics and glassfiber composite 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 intubate internal layer is made up of the natural fibre of porous, and is more obvious when having formed the buffer layer, particularly rolling element of comparing the softer buffering rolling element momentum of metal material track and need in the back device, change moving direction; The rolling element exposure phase is to softer internal layer, and its irregular collision and shock energy are weakened, thereby have reduced noise; The internal layer porous fibre contains lubricant oil, and after rolling element contacted, intubate internal friction coefficient significantly reduced.The utility model is installed in the slide block and back device of rolling guide-rail pairs, and the mode of traditional oily maintenance rolling element of forgoing has adopted unique double layer construction, and plays the General of self oiling, slide block damping, whole noise reduction.

Embodiment

Below, in conjunction with embodiment, the utility model is further described.

With reference to accompanying drawing; The utility model comprises the internal layer 2 processed by the porous natural fibre that contains lubricant oil hole 3 and by engineering plastics or engineering plastics and glass fibre compounded outer 1; Internal layer 2, outer 1 cross section are ring, internal layer 2 with outer 1 compound be one.The engineering plastics outer tube adopts Shooting Technique to be shaped; Pipe in the natural fibre, the porous layer that adopts rolling technology to be shaped is used with the engineering plastics outer tube; Porous layer comprises lubricant oil, and lubricant oil is used quiet lubricant oil.Slide block in the utility model and the linear rolling guide is used, and is placed in the stream ball hole of slide block, can play that rolling element is lubricated, the effect of slide block damping, whole noise reduction.The utility model has proposed new innovation to the control mode of conventional lubrication, damping, noise reduction.In the slide block of linear rolling guide, add selflubricating damping noise reduction intubate, play that rolling element is lubricated, the General of slide block damping, whole noise reduction.
