Abstract

The invention relates to the field of bridge supports, and discloses a rolling ball support, which includes an upper support body and a lower support body, and a support member is arranged between the upper support body and the lower support body, and the support member includes: steel balls The middle part of the bottom surface of the upper support body is a convex surface, the middle part of the top surface of the lower support body is a concave surface, several steel balls are placed on the concave surface of the lower support body, and the upper support body is placed on the steel balls. A ball bearing provided by the present invention, steel balls are arranged between the upper bearing body and the lower bearing body, which can not only realize the vertical support function of the bearing, but also make the upper bearing body can be opposite to the lower bearing body Displacement in any direction can also realize functions such as horizontal displacement and torsional displacement of the support. Due to the use of rolling contact conditions by using steel balls, the earthquake adaptable frequency range of the support is greatly improved, and at the same time it has good energy dissipation capacity, thus effectively improving the shock absorption and isolation effect.

Description

technical field [0001] The invention relates to the field of bridge supports, in particular to a rolling ball support. Background technique [0002] The bridge bearing is one of the important components of the bridge structure. Commonly used bridge bearings include plate rubber bearings, pot rubber bearings and spherical bearings. Among them, spherical bearings are widely used because of their large bearing capacity, large translational capacity, large rotational capacity, and excellent durability. [0003] Bridge spherical bearings are divided into two-way sliding spherical bearings, one-way sliding spherical bearings and fixed spherical bearings according to whether sliding is allowed. A two-way sliding ball bearing refers to a ball bearing that can slide freely in two horizontal directions; a one-way sliding ball bearing refers to a ball that can slide freely in one horizontal direction and is not allowed to slide in the other horizontal direction. Type bearing; fixed ...
