Abstract
The utility model provides an improved rolling component retainer, wherein a plurality of distance pieces are arranged on a retainer in parallel; tensile straps are arranged in the distance pieces on both sides of the retainer and the distance pieces which are arranged row by row; the distance pieces on the retainer are in an aspherical shape, and spaces which can contain rolling elements are arranged among the distance pieces to prevent the rolling elements from dropping out. The retainer of the utility model belongs to flexible bending; the rolling elements are contained in a linear slide rail unit when the retainer acts and turns circularly, which can avoid the unsmooth performance because of the extruding interference generated between the rolling elements and the distance pieces; as groove devices are arranged on the distance pieces, greasing substance can be remained, and the smooth performance can be increased when the retainer cyclically acts; owing to large tensile strap area and bearing stretching resistance, the service life of the retainer can be prolonged.
Description
Technical field
The utility model provides a kind of improved rolling element retainer.
Background technology
Distance piece D on the rolling element retainer A of general linear slide rail adopts single-row mode to arrange (as shown in Figure 1), and when slide block C cocycle action is turned (as shown in Figure 3), distance piece D and rolling element B can interfere extruding, cause circulation to have some setbacks (as shown in Figure 2); Because of distance piece D adopts single-row mode to arrange, the tension band E of its retainer A only can be arranged at both sides (as shown in Figure 1) again, so the stretching resistance that retainer A can bear is little, easily makes its fracture, and influences the life-span of linear slide rail.
Content of the present utility model
Therefore, how above-mentioned shortcoming is forgone, be the place of the technical difficulties of inventor institute desire solution.In view of this, the inventor is professional attainment and the technical concept that is possessed with itself and itself is engaged in this work experience for many years, through studying and improveing repeatedly, the utility model is born.
It is a kind of improved rolling element retainer of the utility model, formed by rolling element retainer and rolling element, it is characterized in that: this rolling element retainer is provided with a plurality of distance pieces, and arrange in mode arranged side by side, its rolling element distance piece is to be an aspherical surface shape, and the edge is provided with groove, and is to be provided with the tension band with both sides between each distance piece row, forms three tension bands.
The utility model is further characterized in that: this rolling element is meant spherical or the column rolling body.
Prevent the ccontaining rolling element greasing substance of being detained when turning and on the groove that interferes of distance piece.
Provide a kind of improved rolling element retainer by technique scheme the utility model, wherein this retainer is provided with a plurality of distance pieces of arranging according to mode arranged side by side, is provided with the tension band in the distance piece between both sides and row and the row; Distance piece on the retainer is the aspherical surface shape, and be provided with between distance piece and the distance piece can ccontaining rolling element the space, drop to prevent rolling element.Retainer of the present utility model is to belong to the pliability bending, and when the ccontaining rolling element of retainer cycle event in the linear slide rail group is turned, can avoid rolling element and distance piece to interfere the having some setbacks property that extruding causes, and because of distance piece is provided with groove arrangement, the greasing substance of can being detained, the smoothness in the time of more can increasing its cycle event; Because of the tension zone face of retainer is long-pending big, the stretching resistance that can bear is big more, so can improve the service life of retainer again.
Be convenient and understand content of the present utility model, and the effect that can realize, conjunction with figs. is enumerated a specific embodiment now, detailed introduction is described as follows:

Specific implementation
At first seeing also shown in Figure 4ly, is to be schematic perspective view of the present utility model.Improved rolling element retainer of the present utility model, formed by a bendable crooked retainer 1 and rolling element 2, wherein retainer 1 is provided with a plurality of distance pieces of arranging according to mode arranged side by side 11, be provided with tension band 13 between both sides and distance piece 11 row, and distance piece 11 is to be an aspherical surface shape, and being provided with groove 12, it can be ccontaining for rolling element 2.
See also Fig. 4,5 and shown in Figure 6 again, when retainer 1 is placed on the slide block 3, when it is turned in circulation, retainer 1 is provided with groove 12 because of distance piece 11, make 2 of its distance piece 11 and rolling elements be unlikely to interfere, push, because of between distance piece 11 row and both sides are provided with tension band 13 (representing with a, b), it is big because of tension band 13 formed areas again, and the pulling force that can bear is also big more.
Seeing also shown in Figure 6ly at last, is to be another embodiment of the present utility model.The rolling element of this roller retainer 5 is to adopt roller rolling element 4, and its roller retainer 5 is by rolling formula rolling element 4 with mode permutation and combination arranged side by side, and hands over it fixing at interval by distance piece 11, and its main purpose is; This roller retainer 5 is with mode permutation and combination arranged side by side by roller rolling element 4.
Rolling element retainer of the present utility model is when the circulation turning action, because of the distance piece on the retainer is provided with groove, make and be unlikely to the phenomenon that interferes, push between its distance piece and rolling element, and the rolling element of this retainer is to arrange in mode arranged side by side, driven rolling element arranged side by side simultaneously when rolling, it is more smooth and easy to make it to roll; Be provided with tension band a and b between the both sides of this retainer and distance piece row again, the formed area of its tension band is big, therefore the stretching resistance that can bear big more (known approximately steel ball retainer 3 to 5 times), therefore be difficult for taking place the situation of disconnected row, also increase relatively its service life, and the assembling of rolling element and retainer is also more easy.
For making the utility model more show its progressive and practicality, hereby with to be commonly used for a comparative analysis as follows:
1, when circulation was turned, distance piece and rolling element interfered easily, and caused the circulation of rolling Have some setbacks.
2, the stretching resistance of tension band is little, and disconnected row situation easily takes place, and service life is short.
The utility model advantage:
1, retainer is when circulation is turned, and distance piece and rolling element do not interfere, and it is smooth and easy to circulate. (advantage of aspheric surface shape space and groove)
2, tension band area is big, and the stretching resistance height is difficult for taking place the disconnected situation that is listed as.
3, long service life.
4, assembling easily.
5, the value on tool commercial and industrial circles and the industrial community.
In sum, the utility model is being broken through under the previous technical pattern, has reached the effect that institute's desire is promoted really, and also non-be familiar with this skill person institute easily full of beard reach; Moreover not open before the utility model application, the progressive of its tool, practicality show the application important document that has met novel patent, propose novel application in accordance with the law.
