Abstract
The invention discloses a kind of lubricating fitting and lubricating method of ball screw pair, relate to ball screw pair lubrication technical field.This lubricating method adopts grease lubrication, but grease is not be painted in nut rolling way, but grease is joined in the box body linked together with the nut of leading screw, in guide screw movement process, grease is dynamically applied to the raceway face of leading screw, reaches good lubrication effect.Advantage is: this method avoid the shortcoming that drop lubrication can not set up effective elastohydrodynamic lubrication film, overcoming again traditional grease lubrication mode is painted in nut rolling way by lubricating grease, ball high-speed motion shears the problem of temperature rise that lubricating grease causes, namely ensure lubrication effect, unlikelyly again cause large temperature rise.
Description
Technical field
The present invention relates to ball screw pair lubrication technical field, specifically a kind of ball screw pair lubricating fitting and
Lubricating method.
Background technique
Precise ball screw pair is the key feature of numerical control machine tool, and frictional behaviour is one of its important performance indexes.Friction can cause the wearing and tearing of lead screw pair raceway, affects the working life of lead screw pair, at high speeds, can cause thermal stretching and affect the positioning precision of leading screw by fricative temperature rise, and reasonably lubrication effectively can improve the frictional behaviour of lead screw pair.The domestic lubrication problem research specially for ball screw pair is less, normally the lubrication of reference bearing takes corresponding lubricating system, general employing grease lubrication and drop lubrication two kinds of modes at present, the former is generally used for the lubrication of low speed leading screw, and high-speed ball screw pair selects the mode of the latter and drop lubrication usually.Research shows, under current level of processing and drop lubrication mode, for ball and leading screw and nut rolling way Contact Pair, belong to boundary lubrication condition, be difficult to set up complete elastohydrodynamic lubrication oil film, lubrication state is comparatively severe, and this is also that to result in domestic lead screw pair high speed performance poor, the major reason that the life-span is shorter.Under comparable operating conditions, lubricating grease more easily sets up stable lubricant film compared with lubricant oil, has better lubrication effect.The conventional grease lubrication mode of lead screw pair is painted into by lubricating grease in feed screw nut raceway, and the lubricated fat of ball surrounded.But the shortcoming of lubricating grease is poor fluidity, and cooling effect is bad, and the fibrous structure of lubricating grease repeatedly sheared by ball in high speed motions, stirs loss comparatively greatly, cause the temperature rise of leading screw, the positioning precision of the influence of thermal deformation leading screw that temperature rise causes.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of ball screw pair lubricating fitting and
Lubricating method, is dynamically applied to lubricating grease above leading screw raceway and plays lubrication.
The present invention realizes with following technological scheme: a kind of ball screw pair lubricating fitting, the leading screw of ball screw pair is set with a box body, is respectively equipped with spring sheet and silk screen, is provided with lubricating grease between spring sheet and silk screen in the box body of leading screw both sides; Box body is provided with the adjustment screw of adjustment spring pressure, nut surface of contact in box body and ball screw pair is provided with grease adding mouth, box body and nut, between spring sheet and silk screen, are fixed together through grease adding mouth by sealing screw by grease adding mouth.
A kind of ball screw pair lubricating method, adopts above-mentioned lubricating fitting, lubricating grease is dynamically applied to leading screw raceway face; Concrete steps are as follows: by grease adding mouth, box body is filled lubricating grease, tighten sealing screw, adjust spring pressure by adjusting screw, then box body is installed on leading screw, through grease adding mouth, box body and nut are fixed together by sealing screw, in lead screw pair working procedure, under the pressure effect of spring sheet, lubricating grease, through the mesh of silk screen, is dynamically applied in leading screw raceway face, form stable lubrication adipose membrane in leading screw raceway face, play good lubrication.
The invention has the beneficial effects as follows: pass through box body, lubricating grease is dynamically applied in leading screw raceway face, overcome the temperature rise phenomenon produced due to the lubricating grease in ball high speed repeatedly shearing nut when drop lubrication can not form the shortcoming of elastohydrodynamic lubrication oil film and conventional grease lubrication, good lubrication effect can be played, the problem of temperature rise of leading screw can be avoided again.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
In figure: 1, leading screw, 2, nut, 3, box body, 4, lubricating grease, 5, spring sheet, 6, adjustment screw, 7, grease adding mouth, 8, silk screen.
Embodiment
As shown in Figure 1, a kind of ball screw pair lubricating fitting, the leading screw 1 of ball screw pair is set with a box body 3, is respectively equipped with spring sheet 5 and silk screen 8, is provided with lubricating grease 4 between spring sheet 5 and silk screen 8 in the box body 3 of leading screw both sides; Box body is provided with the adjustment screw 6 of adjustment spring sheet 5 pressure, nut 2 surface of contact in box body and ball screw pair is provided with grease adding mouth 7, box body 3 and nut, between spring sheet 5 and silk screen 8, are fixed together through grease adding mouth by sealing screw by grease adding mouth.The nut of device and ball screw pair is linked together, axially moves along leading screw with nut.This device is symmetrical, has only drawn the side of leading screw, eliminate opposite side in Fig. 1.
Adopt above-mentioned lubricating fitting, lubricating grease is dynamically applied to leading screw 1 raceway face; Concrete steps are as follows: by grease adding mouth, box body is filled lubricating grease, tighten sealing screw, adjust spring pressure by adjusting screw, then box body is installed on leading screw, through grease adding mouth, box body and nut are fixed together by sealing screw, in lead screw pair working procedure, under the pressure effect of spring sheet, lubricating grease, through the mesh of silk screen, is dynamically applied in leading screw raceway face, form stable lubrication adipose membrane in leading screw raceway face, play good lubrication.
