Description
Technical field
The utility model relates to mechanical, particularly a kind of mute type linear slide rail chain belt structural improvement.
Background technology
As accompanying drawing 1 to shown in the accompanying drawing 6, retainer structural representation for common linear slide rail, wherein, the tension band E inflexibility section F length of this retainer C can't reach the longizationest greater than flexible section G length or flexible section G length, and the sectional area that this linking belt D and tension band E link is excessive, cause the inflexibility section F length of tension band E long, and make retainer C produce big friction impedance at circulation tow-away zone H; The sectional area of this linking belt D and tension band E binding is too little again, easily make retainer C in circulating motion, rupture in this junction, this distance piece A covers rolling element B with ball bread again, in circulating motion, can produce big friction drag, and in the H of circulation tow-away zone, can form a pinching effect nidus N, and produce the shortcoming of big pinching effect, and for example shown in accompanying drawing 5 and the accompanying drawing 6, retainer structural representation for the common linear slide rail of another kind, wherein the cross section of this tension band M is square, the sectional area of this guide channel I also is square, therefore the friction drag in circulating motion is big, and fluted L device among this distance piece K though can reduce friction drag in the circulating motion, also has the pinching effect to take place in the circulation tow-away zone, and can't make the contact point of rolling element J and distance piece K maintain the center position of rolling element J, and the shortcoming that the friction drag in the tow-away zone that causes circulating increases; Moreover, fluted L device in the middle of this distance piece K, when penetrating the demoulding neither easily, and easily cause the shortcoming of size distortion after the demoulding; In sum, the retainer of common linear slide rail is anxious needs to wait to improve.
The utility model content
According to the purpose of this utility model, there are many shortcomings at the retainer of above-mentioned common linear slide rail, a kind of mute type linear slide rail chain belt structural improvement is provided, its conception plans is that the tension band adopts circular section design, the resistance of reducing friction; Linking belt adopts the sectional area of vertical arbitrary position to be all 2 times optimum design value of tension band sectional area; Distance piece is provided with the unfilled corner device, and can not produce big friction drag and pinching effect in circulating motion: the contact point that can be designed to rolling element and distance piece maintains the center position of rolling element, to reduce the friction drag in the circulation tow-away zone; Its concrete structure is made of half clad type storage tank, tension band, linking belt, distance piece and rolling element, wherein, be respectively equipped with a linking belt in the distance piece both sides, link by this linking belt and tension band, and form half clad type storage tank between this distance piece and the distance piece, can insert in this half clad type storage tank for rolling element; The tension band of this tension band and opposite side can be non-rectilinear formula departure distance again, to make things convenient for the position configuration of tension band guide channel; And the tension band only may contact with guide channel with the line friction mode in the whole circulation path, and wherein the equivalent load value that converts static load to of the dynamical load under the minim gap space is about 2 times dynamical load value; Therefore, the sectional area of this linking belt and tension band and distance piece binding is 2 times a tension band sectional area; This distance piece is the arc varied cross section that an end is thick and the other end is thin again, and cooperate the linking belt down either side to be provided with the unfilled corner device, when benefiting shaping and demoulding, convenient effect of taking out, and this unfilled corner device can increase distance piece in the ability of bearing pinching effect of rolling element when circulation is turned, to avoid rolling element that the pinching effect of rolling element takes place when circulation is turned, and keep the contact point of rolling element and distance piece to be in the center, simultaneously, take out usefulness when helping shaping and demoulding, to reach practical purpose.

The specific embodiment
As accompanying drawing 7 to shown in the accompanying drawing 12, the utility model is made up of half clad type storage tank 2, tension band 3, linking belt 6, distance piece 4 and rolling element 5, wherein, these distance piece 4 both sides are respectively equipped with linking belt 6, link by this linking belt 6 and tension band 3, and form half clad type storage tank 2 between this distance piece 4 and the distance piece, can insert in this half clad type storage tank 2 for rolling element 5; This tension band 3 can be non-rectilinear formula departure distance 10 with the tension band of opposite side again, to make things convenient for the position configuration of tension band guide channel, and tension band 3 only may contact with guide channel 9 with the line friction mode in the whole circulation path, and wherein the equivalent load value that converts static load to of the dynamical load under the minim gap space is about 2 times dynamical load value; Therefore, the sectional area that this linking belt 6 and tension band 3 and distance piece 4 link is 2 times tension band 3 sectional areas, this distance piece 4 is the arc varied cross section that an end is thick and the other end is thin, as shown in Figure 11, and cooperate linking belt 6 down either side to be provided with unfilled corner device 7, when benefiting shaping and demoulding, the effect of convenient taking-up; Unfilled corner device 7 can increase distance piece 4 in the ability of bearing pinching effect of rolling element 5 when circulation is turned, to avoid rolling element that the pinching effect of rolling element 5 takes place when circulation is turned, and keep the contact point of rolling element 5 and distance piece 4 to be in the center, simultaneously, taking-up usefulness when helping shaping and demoulding is to reach practical purpose;
Shown in accompanying drawing 12 and accompanying drawing 13, when driving retainer 1 in rolling element 5, tension band 3 makes circulation time, tension band 3 contacts with guide channel 9 with the line friction mode in the whole circulation path, and be the arc varied cross section that an end is thick and the other end is thin by this distance piece 4, to avoid rolling element 5 when circulation is turned, the pinching effect of rolling element 5 takes place, and can keep the contact point of rolling element 5 and distance piece 4 to be in the center, and be provided with unfilled corner device 7 in linking belt 6 down either side, when benefiting shaping and demoulding, convenient effect of taking out, this tension band 3 and linking belt 6 are connected the thickness at place less than the external diameter of tension band 3 sectional areas again, thereby improve stretching resistance; Change the tension band 11 that is made as discontinuous as tension band 3, when rolling element 5 is turned in circulating, also can reach and rotate effect smoothly retainer 1.
