Embodiment
Below in conjunction with the drawings and the specific embodiments the present invention is described in further detail.
At first, consult Fig. 3, Fig. 4 and shown in Figure 15, the present invention has the linear slide rail of synchronous connector, comprises: a slide rail 1, and both sides respectively are provided with groove 11; One slide block 2 is a ㄇ font body and is sheathed on this slide rail 1, and makes linear reciprocating motion with slide rail 1, is provided with the rolling groove 21 to groove 11 that should slide rail 1 in the inboard, and is provided with axial through hole 22 in both sides; Some rolling assemblies (being ball A or roller P); Two end cap 3 respectively is installed in these slide block 2 two ends and is provided with backflow road 31.
This backflow road 31 is connected formation one circulation loop (as shown in Figure 4) with this groove 11 and this rolling groove 21 with this through hole 22, be provided with rolling assembly A (or P) in this circulation loop, and this rolling assembly A (or P) is placed on the connector 5 (or 6), the ring bodies 52 (or 62) that this connector 5 (or 6) comprises two or more different radial thicknesss constitutes with a junction 51 (or 61), this joint 51 (or 61) is a strip body, and in the outside of rolling assembly A (or P), in order to connect each ring bodies 52 (or 62); This ring bodies 52 (or 62) correspondence forms between the two adjacent rolling assembly A (or P), and this ring bodies 52 (or 62) therefore can avoid adjacent rolling assembly A (or P) to produce collision, the reduction collision noise with line way of contact maintenance rolling assembly A (or P); But rolling assembly A (or P) to be producing relative movement between rolling friction mode and roller surface (being the surface of groove 11, rolling groove 21), so rolling assembly A (or P) will inevitably produce friction noise with roller surface, and it is as follows to calculate its fricative frequency noise:
1. rolling assembly A (or P) center of circle is by the time of adjacent rolling assembly A (or P) spacing,
2. rolling assembly A (or P) is by frequency (the friction noise frequency of adjacent rolling assembly A (or P) spacing; Frequency is the inverse of time),
So from the above, when distance between each rolling assembly A (or P) equates that not exclusively (during d1 ≠ d2) (as shown in figure 15), then the frequency noise that produced of each rolling assembly A (or P) just not exclusively equates (f1 ≠ f2);
By this, connector 5 of the present invention (or 6) comprises the ring bodies 52 (or 62) of two or more different radial thicknesss, and the thickness of this ring bodies 52 (or 62) can gradually be as thin as the other end by an end of connector 5 (or 6), also can gradually be as thin as two ends by the centre of connector 5 (or 6), make that the distance between each rolling assembly A (or P) is not exclusively equal, so the friction noise that rolling assembly A (or P) and roller surface relative movement are produced can be distributed in each frequency and (see also shown in Figure 17, this figure is that the noise of not equidistant rolling assembly measures signal, with the noise of the equidistant rolling assembly of Figure 16 measure signal can obviously find out after relatively friction noise comparatively average be dispensed to each frequency), and then reduced the acoustic pressure that linear slide rail and toolroom machine are empathized.
