Description

Technical Field

[0001] The utility model relates to the technical field of pot-type rubber bearings, in particular to a pot-type rubber bearing with excellent durability. Background Art

[0002] The pot-type rubber bearing is a new type of bridge bearing composed of steel components and rubber. Compared with other similar pot-type bearings and cast steel roller bearings, it has the advantages of large bearing capacity, large horizontal displacement, and flexible rotation. The pot-type rubber bearing is composed of an upper seat plate, a sealing ring, a rubber plate, a bottom pot and anchor bolts. The working principle of the pot-type rubber bearing is to use the elastic rubber block in the semi-enclosed steel pot cavity, which has the properties of a fluid under a three-dimensional force state, to realize the rotation of the upper structure; at the same time, the low friction coefficient between the polytetrafluoroethylene plate on the middle steel plate and the stainless steel plate on the upper seat plate is relied on to realize the horizontal displacement of the upper structure. The pot-type rubber bearing is disclosed in patent: CN 104343081 B, including: a top support plate, a steel pot and a rubber plate that can be fastened between the top support plate and the steel pot, the side edge of the steel pot is higher than the top surface of the rubber plate; a seal is provided at the contact between the rubber plate and the steel pot.

[0003] However, the existing pot-type rubber bearings on the market have a relatively simple structure. The lower and upper seat plates on the pot-type rubber bearings do not have the ability to flexibly cushion shocks. The sealing ring in the bottom pot is difficult to ensure long-term sealing. In addition, the polytetrafluoroethylene plate on the rubber bearing is easily damaged by moisture, which affects the durability of the pot-type rubber bearing. Therefore, we have made improvements to this and proposed a pot-type rubber bearing with excellent durability. Utility Model Content
