Wind power generation speed-increasing gearbox planet carrier cylindrical roller bearing with stop groove

Abstract

The invention provides a wind power generation speed-increasing gearbox planet carrier cylindrical roller bearing with a stop groove, and relates to the technical field of bearings, wherein the wind power generation speed-increasing gearbox planet carrier cylindrical roller bearing comprises an inner ring body, an outer ring body, an inner space ring and a sealing ring body; the inner ring body comprises an inner ring and cylindrical rollers A, an outer ring of the inner ring is provided with an outer concave ring groove, and ten groups of cylindrical rollers A are rotatably mounted in the outer concave ring groove; the outer ring body comprises two groups of semicircular plates and cylindrical rollers B, inner rings of the semicircular plates are respectively provided with inner grooves, and five groups of cylindrical rollers B are rotatably arranged in the inner grooves respectively; and the two semicircular plates are in butt joint and are connected in the mode that bolt rods penetrate through threaded through holes to form an outer ring, the cylindrical rollers A are opposite to the cylindrical rollers B, and the inner space ring is further inserted between the cylindrical rollers A and the cylindrical rollers B. When a group of cylindrical rollers or a circle of cylindrical rollers are damaged, the use of the bearing is not influenced, and a better sealing effect can be achieved. The problem that the use of the bearing is affected due to the damage of a group of internal cylindrical rollers is solved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a cylindrical roller bearing for a planet carrier of a wind power generation gearbox with a stop groove. Background technique [0002] The wind power gearbox is the core component of the wind power generator. Its function is to increase the lower speed transmitted by the rotating blades to the rated speed of the generator. in the gearbox. At present, the wind power planetary carrier bearing generally adopts the cylindrical roller bearing structure. With the continuous increase of the design power of the fan, the bearing is one of the weakest links of the gearbox. Due to the complex and very harsh working environment of the fan, under the condition of compound load , the existing bearing wears seriously during use and has a low service life. [0003] However, in current bearings, a group of cylindrical rollers inside are damaged, which affects the use of the bearing, and the lu...

AI Technical Summary

Problems solved by technology

At present, the wind power planetary carrier bearing generally adopts the cylindrical roller bearing structure. With the continuous increase of the design power of the wind turbine, the bearing is one of the weakest links of the gearbox. Due to the complex and very harsh working environment of the wind turbine, under the condition of compound load , the existing bearings are severely worn during use and have a low service life

[0003] However, in the current bearing, a group of cylindrical rollers inside is damaged, which affects the use of the bearing, and the lubricating oil inside is easily thrown out, which easily causes the bearing to be damaged due to lack of lubrication.
