Description

Rolling isolation device

The invention relates to a rolling isolation device; in particular to a device for preventing vibration or vibration of a general building structure and a shock absorber for mechanical engineering components. The complex array roller is disposed between the upper and lower two sets of vertically staggered rolling surfaces, and the vertical load is received by the rolling behavior of the roller on the rolling surface, and the vibration is separated, and the complex array roller is driven by the roller. The spacer or the roller retainer is connected to improve the load-bearing capacity of the rolling isolation device and ensure the stability during actuation without overturning.

As shown in Fig. 1, a single ball (02) is placed between the upper and lower circular curved panels (01), and the rolling behavior between the circular curved panels (01) by the balls (02) is achieved. The effect of isolation.

The ball isolation support uses a combination of balls and a circular curved panel. However, because the contact area between the ball and the curved surface is too small, it is almost a point-like contact, which tends to cause excessive stress at the contact point, and the surface is prone to depression or the surface of the ball is liable to be damaged. It situation. In addition, the single-group ball-isolated bearing can be overturned when used alone, and it is more unstable when it is actuated. Therefore, multiple sets of ball-isolated bearings must be used together to ensure the stability when carrying the load.

In order to improve the load capacity of the isolation device, to ensure the stability of the mechanism of the single isolation device and to avoid the risk of overturning of the vibration isolation device, the present invention uses a multi-array roller with a complex array of rolling surfaces to increase the load. The stability of the ability and mechanism actuation, the fixed array of rollers is fixedly connected into a rolling table by a roller spacer or a roller cage, so that the rolling isolation device of the present invention has high bearing capacity and stability during operation. .

As shown in Fig. 2, Fig. 3, and the rolling isolation device shown in Fig. 4, a set of two-way plates (11), a base plate (10), are arranged between the two sets of base plates (10) arranged up and down. A set of rolling tables (30) is separately arranged between the two-way board (11), and the base board (10) is provided with a complex array rolling surface (12), and the upper part and the lower part of the two-way board (11) are individually provided with a complex array. The rolling surface (12), and the upper rolling surface and the lower rolling surface are arranged perpendicularly to each other; the rolling table (30) is composed of a plurality of array rollers (20), and one set of rolling surfaces is arranged with one set of rolling tables, that is, one set The rolling surface is configured with a plurality of array rollers; the roller and the rolling surface are in contact with each other, and the roller can roll back and forth on the rolling surface; the base plate of the upper part of the rolling isolation device can reverse the relative movement of the lower base plate in any direction .

The plurality of array rollers (20) of the rolling table (30) are connected by a roller positioner (301) or a roller holder (302) to form a rolling table (30). In order to make the rolling table (30) on different rolling surfaces consistent, a rolling table locator (304) is provided to connect the complex array rolling table (30), so that the rolling isolation device can greatly enhance the carrying capacity and the mechanism. stability.

The rolling isolation device shown in Fig. 5 is a two-way plate (11) hingedly connecting the rolling table (30), and the rolling surface of the roller (20) on the rolling table (30) on the base plate (10) (12) The way of rolling.

Fig. 6 is a schematic view showing a preferred manner in which the rolling isolation device is disposed on the structure (40).
