For achieving the above object, the utility model proposes the rolling bearing of a kind of easy lubrication, including bearing inner race, roller, retainer, upper back-up ring, lower back-up ring, bearing outer ring, described bearing inner race outer wall is provided with some roller slots, the two ends of bearing inner race are provided with card division, bearing inner race is provided with some lubricating oil outlets, described retainer is looped around outside bearing inner race, retainer is provided with some roller mounting grooves, the cooperation of described roller is arranged on retainer, the periphery of roller is provided with some oil-ways, described upper back-up ring and lower back-up ring are positioned at the both sides of retainer, upper back-up ring and lower back-up ring are all arranged between bearing inner race and bearing outer ring, described bearing outer ring is provided with lubricating oil inlet, the inwall of bearing outer ring is provided with some ball grooves。
As preferably, described card division card is lived in back-up ring and the outside of lower back-up ring, described upper back-up ring and lower back-up ring and is installed symmetrically。
As preferably, when described roller is installed and the position of roller slot is mutually corresponding, and roller and roller mounting groove are connected, and described roller mounting groove is evenly distributed on retainer。
As preferably, the diameter of described lubricating oil inlet is more than the diameter of lubricating oil outlet, and the quantity of described lubricating oil outlet is 4 and is evenly distributed on bearing inner race。
As preferably, described roller periphery is provided with 2 symmetrical oil-ways。
The beneficial effects of the utility model: this utility model by being provided with lubricating oil inlet by bearing outer ring, bearing inner race is provided with lubricating oil outlet, roller is provided with oil-way, lubricating oil is made can uniformly and quickly to lubricate bearing, unnecessary lubricating oil can discharge bearing in time, it is ensured that the lubrication of bearing improves the life-span of bearing；Retainer both sides are provided with upper back-up ring and lower back-up ring, and card division card lives in back-up ring and lower back-up ring, and bearing inner race and bearing outer ring are provided with roller slot so that bearing has a steady good working environment, and retainer is not easily disconnected from。
Feature of the present utility model and advantage will be described in detail in conjunction with accompanying drawing by embodiment。
