Abstract
The utility model discloses a kind of ball screw of tool dust guard, comprise: a screw rod, the outer edge surface of this screw rod is provided with spiral helicine sliding channel; One nut, the perforation that this nut tool one wears for screw rod; Two dust guard, be located at the perforation two ends of nut respectively, this dust guard has a through hole, the inner edge surface of this through hole is provided with the lip towards sliding channel projection, the surface contact of this lip and this sliding channel, and this lip is provided with at least one recess towards the direction of boring a hole, and this recess and this sliding channel keep a gap, the structure characteristic in a gap is kept by the recess set by this dust guard and sliding channel, to reduce the area of contact of this lip and sliding channel, the relative frictional force reduced between the two, and allow ball screw run smooth degree lifting.
Description
Technical field
The utility model relates to a kind of ball screw, refers to a kind of ball screw of tool dust guard especially.
Background technique
Because the continuous research and development of accurate feeding system improve, Linear transmission technology and products thereof becomes most important part in many accurate facility, linear mechanism product miscellaneous has entered within human lives, processing factory and high technology equipment widely, such as: linear slide rail, ball screw etc.; Although the development of linear mechanism technology is very rapid, but consumption user still needs technology constantly to promote, therefore many still problems leaved for development are also produced, and correlation technique industry is also all in positive research and development, effectively can improve the various new creation of linear mechanism, new invention, particularly manyly needing comparatively to stablize, on quiet high-accuracy manufacturing industry facility (such as: wafer processing, CNC equipment etc.), therefore the some techno peasant's point poles of linear mechanism treat that personage adds research and development again and improves at present.
General used ball screw on the market as shown in Figure 5, dust guard 30 is all provided with in nut 10 end of screw rod 20, dust guard 30 mainly uses lip 301 prevent foreign body intrusion and avoid bleeding of lubricant, but the lip 301 of traditional dust guard 30 coordinates with the sliding channel 201 of screw rod 20 because area of contact is excessive, therefore cause frictional force between the two to increase, when nut is run, resistance increases and becomes and have some setbacks, and historical facts or anecdotes has the necessity improveing and progress greatly.
Model utility content
The purpose of this utility model is that providing a kind of can maintain the lip configurations intensity of dust guard and the ball screw of the tool dust guard of the area of contact between reduction with the sliding channel of screw rod.
In order to reach above-mentioned purpose, solution of the present utility model is:
A ball screw for tool dust guard, comprises: a screw rod, and it is strip structure, and the outer edge surface of this screw rod is provided with spiral helicine sliding channel; One nut, the perforation that its tool one wears for screw rod, the inner edge surface of this perforation is provided with the rolling groove of relative sliding channel; Multiple roll piece, is arranged between sliding channel and rolling groove; Two dust guard, be located at the two ends of the perforation of nut respectively, this dust guard has a through hole, the inner edge surface of this through hole is provided with the lip towards sliding channel projection, the surface contact of this lip and this sliding channel, and this lip is provided with at least one recess towards the direction of this perforation, this recess and sliding channel keep a gap.
Preferably, the perforation two ends of described nut are respectively equipped with a containing groove arranged for described dust guard.
Preferably, the external form profile of described recess is arcuation.
Preferably, the external form profile of described recess is ㄩ or U-shaped.
After adopting said structure, the ball screw of the utility model tool dust guard keeps the structure characteristic in a gap by the recess set by dust guard and sliding channel, to reduce the area of contact of this lip and sliding channel, the relative frictional force reduced between the two, and allow ball screw run smooth degree lifting.
