The following will further explain a waterproof bearing of the present invention with reference to the accompanying drawings.
A waterproof bearing is mainly used for waterproofing a bearing, and the waterproof capability of the waterproof bearing is limited only by splashing of water. For example, when the bearing is applied to a wheel, muddy water can be prevented from entering the bearing, and the bearing is prevented from being worn too fast.
As shown in fig. 1, the waterproof bearing includes an outer ring 1, an inner ring 2, and rolling elements 3 disposed between the outer ring 1 and the inner ring 2, a retainer is further disposed between the outer ring 1 and the inner ring 2 for uniformly distributing the rolling elements 3 between the outer ring 1 and the inner ring 2, and raceways matched with the rolling elements 3 are disposed on both the outer ring 1 and the inner ring 2.
As shown in fig. 1, a water blocking member is further disposed between the outer ring 1 and the inner ring 2, the water blocking member includes an inner baffle 5 fixed on the inner ring 2 and an outer baffle 4 fixed on the outer ring 1, the outer baffle 4 is located on a side of the inner baffle 5 away from the rolling element 3, the inner baffle 5 is provided with at least one circle of protruding ribs 6, and the outer baffle 4 is provided with a groove 7 for accommodating the at least one circle of protruding ribs 6. Outer baffle 4 and interior baffle 5 are direct contact not, have certain clearance between outer baffle 4 and the interior baffle 5, and the setting of bead 6 and recess 7 forms labyrinth waterproof construction, plays waterproof purpose. The clearance between the outer baffle 4 and the inner baffle 5 ensures that the friction coefficient of the bearing cannot be increased when the inner ring 2 rotates relative to the outer ring 1, and the performance of the bearing is optimized.
As shown in fig. 1, a water collecting groove 8 is provided on the outer baffle 4, the water collecting groove 8 is located in the extending direction of the inner baffle 5, a drain hole 9 communicated with the water collecting groove 8 is further provided on the outer baffle 4, a water baffle 10 for shielding the drain hole 9 is provided on the outer baffle 4, and a gap for draining water drained from the drain hole 9 to the outside is provided between the water baffle 10 and the outer baffle 4.
The water collecting groove 8 can be formed by bending the outer baffle 4 or directly forming the outer baffle 4. In actual operation, splashed water may enter between the outer baffle 4 and the inner baffle 5 for various reasons, and the water collecting groove 8 is mainly used for collecting the water entering between the outer baffle 4 and the inner baffle 5 and discharging the collected water through the water discharging hole 9 so as to optimize the waterproof performance of the bearing.
The inner baffle 5 can be fixed to the inner ring 2 by: the inner baffle 5 is fixed on the inner ring 2 through a first connecting piece 11, one side of the first connecting piece 11 is bonded on the inner baffle 5, and the other side of the first connecting piece 11 is bonded on the inner ring 2.
