The invention discloses a high-load dustproof double-column angular contact ball bearing for a water pump. The high-load dustproof double-column angular contact ball bearing for the water pump comprises an outer ring, a bearing shaft, a holder, rolling bodies and sealing rings; the outer ring and the bearing shaft are connected in cooperation through the rolling bodies; the rolling bodies are installed on the portion, arranged between the outer ring and the bearing shaft, of the holder; and the sealing rings are arranged between the two ends of the outer ring and the bearing shaft. According to the high-load dustproof double-column angular contact ball bearing for the water pump, the dual-rollway-nest inner integral ball bearing is simplified, one end of the bearing shaft is connected witha flange, a certain force moment can be transmitted, the bearing shaft is provided with involute outer splines, the bearing shaft is connected with a water pump belt wheel through the involute outersplines, the pump body structure is more compact, installing is more convenient, and the centering precision is high; a double-column angular contact ball bearing structure is adopted for the interior, the axial clearance is more reasonable, and the axial load bearing capacity is improved; and due to the arrangement of the sealing rings, a work area of the bearing can be thoroughly isolated from the outside world, it is effectively prevented that outside world dust invades the interior of the bearing, and the service life of the bearing is prolonged.
Description
【Technical field】 [0001] The invention relates to the technical field of bearings, in particular to a high-load dustproof double-row angular contact ball bearing for a water pump. 【Background technique】 [0002] Double row angular contact ball bearings can bear radial load and axial load at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Precision angular contact ball bearings are widely used in key parts of equipment such as machine tool spindles, and their precision directly affects the machining accuracy of the equipment. In particular, the light and narrow series are the most widely used. Due to the high precision and thin wall thickness of this series of bearings, it is easy to deform during the processing and the processing is difficult. Under normal...
