Embodiment
The present invention will be further described below in conjunction with drawings and Examples:
Toroidal groove water lubricating rubbor alloy bearing involved in the present invention is made up of metal or non-metal shell 1 and specific rubber alloy lining cover 2 as shown in Figure 2.Overlap on 2 lubricating structures at the specific rubber alloy lining as shown in Figure 1, designed become in the circumference even distribution with at the distribution Straight Line and Arc groove 3 that axially is in line; Straight Line and Arc groove 3 is to be made of circular arc camber 6, and the radius size of circular arc camber 6 is R 4Have peripheral annular groove 4 on the circumference of neck bush 2, this peripheral annular groove 4 becomes evenly to distribute vertically; Peripheral annular groove 4 has the certain width and the degree of depth; The working surface of adjacent straight line arc groove 3 by 5 three of circular arc camber 7, circular arc camber 8 and circular arc cambers mutually tangent surface form; Working surface is making progress into even distribution week.In Fig. 3, can see the position size of circular arc annular groove 4 on circumference.
The neck bush lubricating structure working principle of design of toroidal groove water lubricating rubbor alloy bearing: adopt by 5 three of circular arc camber 7, circular arc camber 8 and the circular arc cambers working curved surface formed of tangent surface mutually, on the one hand, the easier formation elastic hydrodynamic lubrication of such curved surface forms the moisture film supporting between transmission shaft and bearing; On the other hand, silt and impurity enter into the axle and bearing between surface of contact circular arc camber 5 time, because of the curved surface that connects between this section working curved surface and the groove is respectively circular arc camber 8 and circular arc camber 7, then silt and impurity are easier is excreted in the Straight Line and Arc groove by such curved surface.The Straight Line and Arc groove 3 of circular arc is easier to excrete out silt and impurity.The more favourable drainage silt and the impurity of water channel groove lubricating structure of Straight Line and Arc groove axle 3 and 4 combinations of peripheral annular groove.Uniform in the axial direction peripheral annular groove 4 lubricating structures can block silt and impurity is grown moving of distance at working surface along axial direction, it is excreted in the peripheral annular groove 4, be excreted to outside the bearing by Straight Line and Arc groove 3 again, thereby reduced the Wear Friction of bearing.
The invention process the toroidal groove water lubricating rubbor alloy bearing of multiclass dimension series, wherein toroidal groove water lubricating rubbor alloy bearing internal diameter A, external diameter B, length C, circular arc camber 7 radius Rs 1, circular arc camber 8 radius Rs 2, circular arc camber 5 radius Rs 3, circular arc camber 6 radius Rs 4, parameter situation such as Straight Line and Arc groove 3 numbers, ring groove 4 numbers and ring groove 4 width w, see Table as follows:
