High temperature resistant self-lubricating deep groove ball bearing

Abstract

The invention provides a heat resisting self-lubricating deep groove ball bearing, which comprises an outer ring and an inner ring of a bearing and steel balls arranged between the inner ring and the outer ring. The heat resisting self-lubricating deep groove ball bearing is characterized in that an inner ring rolling groove for clamping the steel balls is arranged in the middle of an outer circular wall surface of the inner ring, an outer ring rolling groove for clamping the steel balls is arranged in the middle of the inner circle wall surface of the outer ring, graphite blocks are clamped among the steel balls, and an anti-dust cover is arranged on the inner circle of the outer ring. The graphite blocks among the bearing steel balls have a self-lubricating function, and can largely increase the rotating flexibility and load bearing capacity, the inner ring and the outer ring can not be locked under high temperature, the steel balls roll in the inner and outer ring rolling grooves of the bearing, and the steel balls can not drop outside the rings when being heated, the bearing is equipped with the anti-dust cover which not only can prevent dusts and soiling solution, but also has strong guiding function, and prevents the graphite blocks being deviated and locked. The metal surface of the bearing goes through high temperature non-rust chemical treatment, which not only enables the bearing to resist heavy loading, impact, wear, oxidation and corrosion, but also to resist high temperature above 500 DEG C.

Description

technical field [0001] The invention relates to a bearing, especially a high temperature resistant self-lubricating deep groove ball bearing. Background technique [0002] Ordinary bearings are basically unusable or have a very short service life under the condition of external heating or spontaneous high heat, which not only delays production, but also causes economic losses. Contents of the invention [0003] The object of the present invention is to provide a self-lubricating deep groove ball bearing that can withstand high temperatures above 500°C in order to overcome the deficiencies of the prior art. It is not only resistant to heavy loads, impacts, high temperatures, wear, but also anti-oxidation and corrosion. [0004] The object of the invention is achieved through the following technical solutions: [0005] The invention includes the outer ring of the bearing, the inner ring and the steel balls between the inner and outer rings. There is a steel ball rolling g...
