The general introduction of the linear slide rail Components Shape in twice working life more than can be improved for the present invention; Then, then by usage operation of the present invention and effect describe in detail as Hou ︰
See Fig. 9, when guide rail 40 is at first time configuration slide block 50, the convex roller 61 of convex roller means 60 is placed in top roller groove 42, in 53, the matrix roller 71 of matrix roller means 70 is placed in below roller groove 42, in 53, the now middle contact position 611 of convex roller 61 and top roller groove 42, the first contact trace face 421 of 53, 531 contact, and keep and the second contact trace face 422, 532 at non-contact condition, and the contact position 712 of matrix roller 71 and below roller groove 42, the second contact trace face 422 of 53, 532 contact, and keep and the first contact trace face 421, 531 at non-contact condition, so this slide block 50 is by convex roller 61, under the rolling circulation of matrix roller 71, normally successfully can carry out Linear-moving along guide rail 40.
See Figure 10, after linear slide rail uses a period of time, roller groove 42, 53 with convex roller 61, the wall that matrix roller 71 contacts has wearing and tearing situation and occurs, now user can carry out the action of second time configuration slide block 50 to guide rail 40, by top roller groove 42, 53 all convex rollers 61 renew totally and make matrix roller 71 into inserts, and below roller groove 42, 53 all matrix rollers 71 renew totally and make convex roller 61 into and insert, matrix roller 71 after so renewing can in unworn second contact trace face 422, 532 contacts, convex roller 61 after renewing can in unworn first contact trace face 421, 531 contacts, make slide block 50 and guide rail 40 can continue normal use, reach the effect improving twice working life whereby.
Certainly, user also can go around, when guide rail 40 first time configuration slide block 50, matrix roller 71 can be installed in top roller groove 42, in 53, convex roller 61 is installed in below roller groove 42, in 53, as shown in Figure 10, by the time when guide rail 40 will carry out second time configuration slide block 50, original convex roller 61 and matrix roller 71 renew totally, the convex roller 61 after renewing is allowed to be installed in top roller groove 42, in 53, matrix roller 71 after renewing is installed in below roller groove 42, in 53, as shown in Figure 9, the effect increased the service life can be reached equally.
See Figure 11, the present invention is when first time configuration slide block 50, two roller grooves 42,53 up and down of guide rail 40 and slide block 50 can select the convex roller 61 installing same types simultaneously, when by the time will carry out second time configuration slide block 50 operation, can change in upper and lower two roller grooves 42,53 adopts matrix roller 71 to insert simultaneously, as shown in figure 12, certain user also can adopt replacing means contrary to the above, equally also can reach the effect improving twice working life.
It is worth mentioning that, if user thinks that the operation that changes that convex roller 61, matrix roller 71 will remove from slide block 50 inside bothers, user also can select whole slide block 50 all to renew together with all convex rollers 61, whole group of matrix roller 71.
In sum, the linear slide rail that the present invention can improve twice working life is mainly in order to improve shorter disappearance in linear slide rail in the past working life, the main technological means of the present invention is convex roller 61 and the matrix roller 71 of use two kinds of different types specifications, convex roller 61 periphery is provided with the middle contact position 611 and non-contact position 612 that diameter varies in size, matrix roller 71 periphery is provided with the middle non-contact position 711 that arrange contrary to convex roller 61 and contact position 712, the roller groove 42 of this guide rail 40 and slide block 50, 53 walls define the first contact trace face 421, 531 and the second contact trace face 422, 532.When selecting to insert roller groove 42,53 with convex roller 61, convex roller 61 can contact with the first contact trace face 421,531 and keep with the second contact trace face 422,532 at non-contact condition, when selecting to insert roller groove 42,53 with matrix roller 71, matrix roller 71 can contact with the second contact trace face 422,532 and keep with the first contact trace face 421,531 at non-contact condition.Utilize described roller 61, the structural characteristics of 71, use wherein one group of roller means 60 (70) and wherein a contact trace face 421 first, 531 (422, 532) contact, so this slide block 50 can successfully normally movement on guide rail 40, when this contact trace face 421, 531 (422, 532) after producing wearing and tearing, adopt another group roller means 70 (60) to another contact trace face 422 as long as change, 532 (421, 531) contact, another group roller means 70 (60) can avoid contact trace face in damaged condition, and roll on completely newly complete contact trace face, reach the effect doubling to increase the service life whereby.By described technological means, linear slide rail of the present invention and linear slide rail in the past do one and compare, the present invention allows linear slide rail can improve the working life of twice, especially linear slide rail is widely used in aerospace industry, automotive industry, on metalworking machine and other industrial machines, the present invention makes the service life of these machineries more permanent, extremely great help is had for mechanic's industry, and guide rail 40 of the present invention is under the state having wearing and tearing, only need change the roller 61 (71) of inserting different types, do not need as linear slide rail needed whole remove replacing and again correct in the past, therefore replacing operation of the present invention is more quick simple and convenient, and effectively can save the cost of guide rail steel.
