High-bearing gear bearing

Abstract

The invention relates to a high-bearing gear bearing. The gear bearing comprises an outer ball rail, an inner ball rail and ceramic rolling parts. The ceramic rolling parts are located between a rolling way of the outer ball rail and a rolling way of the inner ball rail. Two annular oil seals are further included between the outer ball rail and the inner ball rail and are located on the two sidesof the multiple ceramic rolling parts correspondingly. The high-bearing gear bearing is characterized in that the rolling ways between the outer ball rail and the inner ball rail are of a dual rollingway structure, and the two rolling ways are spaced by 30 mm to 50 mm; and a gear portion is further arranged on the outer side face of the outer ball rail. According to the high-bearing gear bearing,the bearing and a gear are integrally designed, that is, the gear and the outer ring of the gear are designed into an integrated structure, the number of parts is effectively reduced, the mass is reduced, and meanwhile stability of power transmission can be improved. Meanwhile, the dual rolling way structure is adopted by the high-bearing gear bearing, the bearing performance of the bearing is greatly improved under the condition that the boundary dimension of the bearing is not increased, and the operating requirement of a wind power variable pitch bearing is met better.

Description

technical field [0001] The invention relates to a bearing, in particular to a high-load gear bearing. Background technique [0002] Bearings are more commonly used fixed parts in construction machinery. With the rapid development of social economy, the market demand for bearings is increasing, and the requirements are getting higher and higher.
