Description

Direct Action Type guide

Technical field

This utility model relates to Direct Action Type guide, and it is equipped with the lubricant supply part containing lubricant.

Background technology

In recent years, for proposing following problem from the grease nipple supply lubricant Direct Action Type guide that rolling element is lubricated being arranged on slide block, namely when hot environment uses, it has to repeat to feed in short-term.

In first technology, there is the technology shown in Japanese Unexamined Patent Publication 6-346919 as what this part was improved.This technology is formed as, by the rubber containing lubricant or lubricant supply part, the seal member being arranged on the slide block of Direct Action Type guide.The lubricant oozed out continuously between long-term from this seal member can automatically supply to the rolling element closed circuit of slide block.

Utility model content

The purpose of this utility model is in that, it is provided that a kind of Direct Action Type guide, and this Direct Action Type guide is provided with gap between lubricant supply part and the guide rail containing lubricant, it is possible to reduce the abrasion of sealing device, additionally it is possible to maintain sealing in long period.

In order to solve above-mentioned problem, this utility model adopts such a way.

Namely, a kind of Direct Action Type guide, it is fitted together in unoccupied place, guide rail upstream slide block, this guide rail has rolling element rolling groove on side and axially extends, this slide block has by the load rolling element rolling groove relative with the rolling element rolling groove of described guide rail, and via bending the rolling element circulation road of the rolling element return road composition that the both ends with this load rolling element rolling groove, the road link, circulate in road at this rolling element and be filled with the multiple rolling elements making described slide block along described guide rail relative movement, and, the both ends of the surface of described slide block have the sealing device sealed by the opening in the gap between slide block and guide rail, described Direct Action Type guide is characterised by,

End face side at described slide block, by close to described sealing device with the lip of described guide rail contact in the way of be equipped with the lubricant supply part containing lubricant, the lower surface of the described lubricant supply part containing lubricant does not have the upper surface with described guide rail, the side of the described lubricant supply part containing lubricant and the contacts side surfaces of described guide rail.

Utility model effect

According to Direct Action Type guide of the present utility model, between lubricant supply part and the guide rail containing lubricant, it is provided with gap, it is possible to reduce the abrasion of sealing device, additionally it is possible to maintain sealing in long period.

Detailed description of the invention

In FIG, on square guide rail 1, set up, in the mode that can move axially relatively, the slide block 2 that shape of cross section is substantially U-shaped.At the axial both ends of the main body 2A of slide block 2, end cap 2B can be installed removably.In this case, in upper surface 1a and the side 1b ridge line section intersected of guide rail 1, it is formed with the rolling element rolling groove 13 being made up of the axial notch of cross section substantially 1/4 circular shape, further, the centre position of the side 1b of guide rail is formed with another rolling element rolling groove 3 that cross section is substantially semi-circular.

Side seal 40 is to have the parts of polyurethane rubber or by the parts of NBR rubber with steel plate bonding with the state welding containing grease on the steel plate with the substantially U-shaped shape of the form fit of end cap 2B, and the face of the inner side of its U-shaped shape can be configured to the upper surface 1a with guide rail 1 and the shape of side 1b sliding contact ordinatedly by the cross sectional shape of the gap sealed mode between slide block 2 and guide rail 1 Yu this guide rail 1.Strengthening part 42 is also the steel plate of the substantially U-shaped shape of the form fit with end cap 2B.But, this strengthening part 42 does not contact with guide rail 1.And, being clipped between these side seals 40 and strengthening part 42 is also the parts of substantially U-shaped shape of form fit with end cap 2B containing lubricant and the lubricant supply part 41 that is made up of polymer, the face of the inner side of its U-shaped shape, in the same manner as the inner surface of side seal 40, becomes the upper surface 1a with guide rail 1 and side 1b noncontact or at least partially can the shape of sliding contact ordinatedly with the cross sectional shape of guide rail 1.

Lubricant supply part 41 arranges in the mode close to the lip of side seal 40 (that is, the inner surface contacted with guide rail 1 of side seal 40).

It addition, strengthening part 42 is also the steel plate of the substantially U-shaped shape of the form fit with end cap 2B.But, this strengthening part 42 does not contact with guide rail 1.And, as shown in Figure 2, it is clipped in the lubricant supply part 41 containing lubricant between these side seals 40 and strengthening part 42 to positively be sealed in the gap (contactless state) between the upper surface 1a of guide rail 1, and making the lower surface 41a of lubricant supply part 41 become following size, this size makes U-shaped shape less with the upper surface 1a of guide rail 1 size contacted somewhat (about 0.1～0.2mm) than it.

Thereby, it is possible to the abrasion in the lower surface 41a of the lubricant supply part 41 upper surface 1a with guide rail 1 are suppressed as Min..

Now, the side 41b of lubricant supply part 41 contacts with the side 1b of guide rail 1.

Thus, there is the effect that foreign body can be suppressed to internal intrusion of Direct Action Type guide to seek the autologous long lifetime of Direct Action Type guide.

Further, since be formed with oil film 43 between the lower surface 41a and the upper surface 1a of guide rail 1 of lubricant supply part 41, it is possible to suppress foreign body to invade to Direct Action Type guide is internal further.
