Abstract

The invention relates to the field of bearings, in particular to a combined sealed bearing. The combined sealed bearing comprises at least one bearing unit and seal rings arranged on the bearing units. Each bearing unit comprises a bearing inner ring, a bearing outer ring and a roller, wherein the roller is clamped between the outer surface of the bearing inner ring and the inner surface of the bearing outer ring, the outer surface of the bearing inner ring and the inner surface of the bearing outer ring are provided with concave areas at the position of the roller, the side walls of the two sides of the bearing outer ring are both provided with clamping protrusions and clamping guide rails, and the clamping protrusions and the clamping guide rails are alternately distributed and located on the same circumference. When the combined sealed bearing is used, according to the dimension of a needed bearing, a certain number of bearing units are selected for adaption, every two adjacent bearing units are connected through the clamping protrusions and the clamping guide rails on the surface of one side, the demand for bearings of different dimensions is met, and the seal performance of the bearing is improved.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a combined sealed bearing. Background technique [0002] At present, the sealed double-row cylindrical roller bearings produced on the market are usually single-layer sealed bearings, that is, a sealing ring is installed on each end of the bearing; the contact between the sealing lip and the sealing groove on the high-speed rotating inner ring is very easy to wear. Bearings are used in lawnmowers and harvesters in harsh external environments, and harmful substances such as dust, moisture, and foreign matter continuously invade the interior of the bearings. Dust, moisture, and foreign matter cause the grease to form sludge in the bearing, which greatly reduces the lubrication performance of the bearing and reduces the service life of the bearing; especially for some occasions where the working conditions are relatively harsh and the bearing needs to be well sealed and lubricated, the exist...
