A rubber bearing

Abstract

The invention discloses a rubber bearing and relates to the technical field of installation tooling. The rubber bearing includes an outer bushing and an inner bushing. The outer bushing is arranged coaxially outside the inner bushing. Both the outer bushing and the inner bushing are ring-shaped. The outer diameter of the outer bushing matches the inner diameter of the steel pipe. The inner diameter of the outer shaft sleeve matches the outer diameter of the inner shaft sleeve, and the inner diameter of the inner shaft sleeve matches the outer diameter of the long shaft, so the rubber bearing can be arranged between the long shaft and the steel pipe. And the outer shaft sleeve is made of fluororubber material, the outer shaft sleeve can firmly fix the long shaft in the specified position in the steel pipe through its own tension force, preventing the long shaft from deflecting when it rotates, so as to contact the steel pipe and cause vibration , produce noise and wear steel pipe. The inner shaft sleeve is made of engineering plastics and graphite material, which has good wear resistance. Therefore, the rubber bearing can realize the supporting and vibration-absorbing effect on the long shaft, and improves the safety and reliability during power transmission.

Description

technical field [0001] The invention relates to the technical field of installation tooling, in particular to a rubber bearing. Background technique [0002] The power transmission mode of the long-axis deep well pump is long-axis power transmission. Usually, the motor arranged on the deck surface transmits the power to the long-axis deep well pump arranged in the liquid cargo tank, that is, the motor and the long-axis deep well pump pass through the long-axis deep well pump. Shaft drive connection. A steel pipe for protecting the long shaft is usually sheathed outside the long shaft. [0003] Since the distance from the deck to the long-axis deep well pump is relatively long, generally 7-30 meters, the long axis is easily deflected during rotation, causing vibration and noise, which reduces the safety and reliability of power transmission. Contents of the invention [0004] The embodiment of the present invention provides a rubber bearing, which can improve the safety a...
