Description

Sized cross roller bearings with introns

Technical field

The present invention relates to a kind of bearing, particularly relates to a kind of sized cross roller bearings with introns.

Background technology

Just as, the introns of sized cross roller bearings disclosed by No. 4440366 patent of JP publication, it can be learnt by the 3rd figure of the patent, introns are located in the track of a rectangle, and keep certain interval with track, and it can be learnt by the 4th figure, two adjacent rollers are to intersect the both sides that pattern is arranged in an introns, but, bearing is in actual moving process, because roller can impose a pushing force to introns, and the wall of introns toward track is caused to move, so that introns produce interference with track, cause to have some setbacks during bearing operation, stuck phenomenon even occurs, therefore how to avoid because roller pushes the introns as one of this area Research Emphasis.

The content of the invention

It is an object of the invention to provide a kind of sized cross roller bearings with introns, its introns can absorb the pushing force of roller.

Another object of the present invention is to provide a kind of sized cross roller bearings with introns, its introns can be convenient to assemble introns to bearing load path when, whether the angles for recognizing introns correct.

In order to reach above-mentioned purpose, solution of the invention is：

A kind of sized cross roller bearings with introns, comprising：One outer shroud, it has the outside track of a ring-type；One inner ring, it has the inner orbit of a ring-type, and the inner ring is arranged on the inside of the outer shroud, and the outside track forms a load path with inner orbit；One scrolling module, it is made up of multiple rollers with introns, an introns are provided between two adjacent rollers, two adjacent rollers are in cross arrangement, the two sides of each introns respectively have the maintaining part of a relative roller, each maintaining part and the roller-contact, and each introns have the cambered surface and two planes being provided adjacent to two maintaining parts, the cambered surface is connected with two planes, the cambered surface is provided with a spring groove, and the spring groove both sides are defined as elastic portion, and the elastic portion deforms because roller imposes strength, two planes are to be positioned at an angle setting, and the angle is between 80 degree ~ 100 degree.

Further, the thickness of the cambered surface is more than the thickness of two planes.

Further, the maintaining part is a curved surface, and its radius curve is equal to or more than the radius curve of roller.

After said structure, when roller, which imposes a pushing force, gives introns, the sized cross roller bearings that the present invention has introns can absorb the pushing force of roller by the elastic portion of the spring groove, and avoid introns displacement and touch the wall of load path.And the design of two planes can corresponding inner ring inner orbit surface, therefore when assemble the introns, by vision judge two planes whether to should the surface of inner orbit can be determined whether that assembling is correct, the time-histories assembled with saving.

Embodiment

In order to which technical scheme is explained further, below by specific embodiment, the present invention will be described in detail.

Refer to shown in Fig. 1 to Fig. 6, be a preferred embodiment of the present invention, the present embodiment has the sized cross roller bearings of introns, is to include：One outer shroud（1）, it has the outside track of a ring-type（11）；One inner ring（2）, it has the inner orbit of a ring-type（21）, the inner ring（2）It is arranged at the outer shroud（1）Inner side, the outside track（11）With inner orbit（21）Form a load path；One scrolling module, it is by multiple rollers（3）With introns（4）Form, two adjacent rollers（3）Between be provided with an introns（4）, the adjacent roller of two-phase（3）In cross arrangement, the introns（4）Two sides respectively there is the relative roller（3）Maintaining part（41）, the maintaining part（41）With roller（3）Contact, maintaining part（41）For a curved surface, its radius curve is equal to or more than roller（3）Radius curve, and the introns（4）With with two maintaining parts（41）The cambered surface being provided adjacent to（42）And two plane（44）, the cambered surface（42）With two planes（44）Connection, the cambered surface（42）Provided with a spring groove（421）, the spring groove（421）In the circumferential angle of the cambered surface（P）For 90 ~ 180 degree, and the spring groove（421）Both sides are defined as elastic portion, and each elastic portion system can be because of the roller（3）Impose strength and deform, two planes（44）Between be positioned at an angle（Q）Set, the angle（Q）Between 90 degree ~ 135 degree, the cambered surface（42）Thickness（S）More than two planes（44）Thickness（T）.

Furthermore it is by the outer shroud when scrolling module is loaded in load path（1）Set filling hole（12）The load path is inserted, and after filling up load path, then by a filling member（5）Fill in the filling hole（12）, and by a pin（6）It is inserted in the outer shroud（1）The first pin-and-hole set（13）The filling member is passed through afterwards（5）The second pin-and-hole（51）It is arranged in the outer shroud again afterwards（1）The other end the first pin-and-hole（13）, and in the assembling introns（4）When can by visual type differentiate two planes（44）Whether set towards default direction, for example whether towards outside track（11）Or inner orbit（21）Surface set.

Comprehensive institute is above-mentioned, and practicality of the invention should undoubtedly, in addition, in the feature technology gone out disclosed by this case embodiment, all publications are not seen before application and, be not also disclosed use, the fact that not only promote with effect as described above, with more additional benefit that can not be indiscreet and negligent, therefore, novelty of the invention and creativeness have all met patent statute, and whence proposes the application of patent of invention in accordance with the law, request to give and examine and grant quasi patent early, true feeling moral is just.
