ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a method for mounting a linear sliding device.
A conventional linear sliding device is composed of a shaft and an outer sleeve fitted around the shaft and sliding in a linear manner relative to the shaft. The outer sleeve is moved in the linear manner relative to the shaft by rolling balls in a ball endless loop formed in the interior of the outer sleeve.
In order to mount and fix the outer sleeve of such a linear sliding device onto a housing, conventionally, a flange portion is provided on an outer circumferential portion of the outer sleeve, and the outer sleeve is mounted and fixed onto the housing by using a mounting hole formed in the flange portion. Alternatively, a key groove is formed along an axial direction of the outer sleeve on the outer circumferential surface of the outer sleeve and a key groove is also formed on the housing. A key is disposed in both key grooves to thereby mount and fix the outer sleeve onto the housing.
However, in the former mounting and fixing method, since the flange portion is formed integrally with the outer sleeve, that is, since the outer sleeve and the flange portion are simultaneously formed by cutting predetermined material, it takes a very long time for the work and at the same time, a weight of the outer sleeve is increased corresponding to the flanged portion.
Also, in the latter mounting and fixing method, it is necessary to machine the key grooves with high precision. A cost for machining the key grooves is very high. Furthermore, it is necessary to effect a slotter work to the inner diameter portion of the housing. It is very difficult to effect the slotter work to increase the working cost. In particular, in the case where the outer diameter of the outer sleeve is small, it is very difficult to work a key groove in the outer sleeve and further difficult to effect the slotter work of the housing, further increasing a manufacture cost.
Also, in addition to the above-described two mounting methods, there is a method in which a hole passing up to a mounting hole into which the outer sleeve is inserted is provided and a bolt or the like is threadedly fitted into this hole to fasten and fix the outer sleeve disposed in the mounting hole. However, this method suffers from a problem that the outer sleeve is deformed because the outer circumferential surface of the outer sleeve is depressed by the bolt or the like.
SUMMARY OF THE INVENTION
In order to overcome the above-noted defects inherent in the prior art, an object of the present invention is to provide a method for mounting a linear sliding device, by which the mounting of the outer sleeve onto the housing is facilitated with high precision and in low cost.
In order to attain this and other objects, according to a first aspect of the present invention, there is provided a method for mounting on a housing an outer sleeve of a linear sliding apparatus having a shaft, the outer sleeve being fitted around the shaft and slidable in a linear manner relative to the shaft, comprising the steps of: engaging any desired position of an outer circumference of the outer sleeve with a stationary member in a convex and concave engagement; and fixing the stationary member to the housing by a fastening member, thereby mounting the outer sleeve on the housing.
Also, according to a second aspect of the present invention, there is provided a method for mounting on a housing a cylindrical outer sleeve of a linear sliding apparatus having a shaft, by inserting the outer sleeve into a mounting hole of the housing, the outer sleeve being fitted around the shaft and slidable in a linear manner relative to the shaft, comprising the steps of: inserting the outer sleeve into the mounting hole; inserting a stationary member in abutment with a recess of an outer circumference of the outer sleeve; and fixing the stationary member around the mounting hole to the housing by a suitable means, thereby mounting the outer sleeve onto the housing.
Also, according to a third aspect of the present invention, there is provided a method for mounting on a housing a cylindrical outer sleeve of a linear sliding apparatus having a shaft, by inserting the outer sleeve into a mounting hole of the housing, the outer sleeve being fitted around the shaft and slidable in a linear manner relative to the shaft, comprising the steps of: inserting the outer sleeve into the mounting hole; inserting a stationary plate with its edge portion being in abutment with an outer circumference of the outer sleeve and a recess having a predetermined length and formed in a direction perpendicular to an axial direction of the outer sleeve; and fixing the stationary member around the mounting hole to the housing by a suitable means, thereby mounting the outer sleeve onto the housing.
Also, according to a fourth aspect of the invention, in the second aspect of the invention, another recess is formed on the outer circumference of the outer sleeve to face with the first-mentioned recess, and the stationary members are inserted into the respective recesses.
Also, according to a fifth aspect of the invention, in the second aspect of the invention, another recess is formed on the outer circumference of the outer sleeve to face with the first-mentioned recess, and the stationary members are inserted into the respective recesses.
Also, according to a sixth aspect of the invention, in the third aspect of the invention, an edge portion to be inserted onto one of an inner surface of the recess and a recess of the stationary member is formed into a taper surface.
Also, according to a seventh aspect of the invention, in the fourth aspect of the invention, an edge portion to be inserted onto one of an inner surface of the recess and a recess of the stationary member is formed into a taper surface.
Also, according to an eighth aspect of the invention, in the fifth aspect of the invention, an edge portion to be inserted onto one of an inner surface of the recess and a recess of the stationary member is formed into a taper surface.
Also, according to a ninth aspect of the invention, in any one of the first through eighth aspects of the invention, a planar stationary plate formed into a substantially L-shape is used as the stationary member.
Also, according to a tenth aspect of the invention, in the ninth aspect of the invention, a recess groove is formed on a side surface of the housing for retaining the side surface of the stationary plate, the stationary plate is provided on the recess groove, and the stationary plate is fixed to the housing at the recess groove by the fastening member, thereby mounting the outer sleeve onto the housing.
Also, according to an eleventh aspect of the present invention, there is provided a method for mounting on a housing an outer sleeve of a linear sliding apparatus having a shaft, the outer sleeve being fitted around the shaft and slidable in a linear manner relative to the shaft, comprising the steps of: providing a plurality of mounting holes in the housing so that a plurality of outer sleeves may be inserted into the plurality mounting holes; inserting the plurality of outer sleeves into the plurality of mounting holes; fitting planar stationary members between the plurality of outer sleeves in abutment with recesses formed in a direction perpendicular to an axial direction of the outer sleeves; retaining the outer sleeves to the housing by the stationary members inserted on both sides of each outer sleeve; and mounting the stationary members onto the housing by a suitable means, thereby mounting and fixing the outer sleeves onto the housing.
Also, according to a twelfth aspect of the present invention, there is provided a method for mounting on a housing an outer sleeve of a linear sliding apparatus having a shaft, the outer sleeve being fitted around the shaft and slidable in a linear manner relative to the shaft, comprising the steps of: providing a plurality of mounting holes in the housing so that a plurality of outer sleeves may be inserted into the plurality mo
