Plastic bearing with good anti-seismic property

Abstract

The invention belongs to the technical field of bearings, and particularly relates to a plastic bearing with a good anti-seismic property. Aiming at the shortcoming and problem that an existing plastic bearing is prone to being abraded and shaking during movement, the following scheme is provided. The plastic bearing comprises a bearing inner ring; the outer ring of the bearing inner ring is movably sleeved and connected with a bearing outer ring; the two ends of the bearing inner ring are movably sleeved and connected with inner ring damping mechanisms in sliding sleeving connection with thebearing inner ring; the two ends of the bearing outer ring are provided with first sliding grooves in sliding sleeving connection with the inner ring damping mechanisms; first containing grooves are formed in the outer ring of the bearing inner ring in the axis direction in an array mode; and second containing grooves corresponding to the first containing grooves are formed in the inner ring of the bearing outer ring in the axis direction in an array mode. The plastic bearing can effectively ensure the effect that intervals between parts of the bearing inner ring and the bearing outer ring areconsistent, reduces friction force between the bearing inner ring and the bearing outer ring during movement, effectively avoids the influence of bounce of a rotary shaft during rotation on the bearing inner ring, and improves the anti-seismic property of the bearing inner ring.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a plastic bearing with good shock resistance. Background technique [0002] The plastic bearings currently used can generally be divided into plastic rolling bearings and plastic sliding bearings; the working principles of plastic rolling bearings and plastic sliding bearings can be distinguished by their names. The friction that occurs when plastic rolling bearings work is rolling friction, while plastic sliding bearings work Sliding friction occurs at the time; the magnitude of rolling friction mainly depends on the manufacturing accuracy; while the friction of plastic sliding bearings mainly depends on the material of the bearing sliding surface; [0003] When the plastic bearing is in use, the eccentric movement of the internal shaft will easily cause friction inside the bearing. In severe cases, the bearing will vibrate during motion, affecting the performance of the bearin...
