Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-4, an automatic aligning double-row deep groove ball bearing comprises an internal ring 1, a heat dissipation baffle 3 is fixedly installed on the upper surface of the internal ring 1 near the edge, an external cover 2 is fixedly installed on the upper surface of the heat dissipation baffle 3, a lubrication pipe 4 is fixedly installed on the inner surface of the internal ring 1 near the middle, and a limiting block 5 is fixedly installed on the outer surface of the internal ring 1 behind the heat dissipation baffle 3;

an oil adding hole 101 is formed in the other outer surface of the built-in ring 1, the position, close to the middle, of the inner surface of the oil adding hole 101 is fixedly provided with an oil adding pipe 102, the position, close to the upper side, of the inner surface of the oil adding pipe 102 is provided with a forward fixed thread 103, a fixed cover 104 is movably mounted on the upper surface of the oil adding pipe 102, the position, close to the middle, of the upper surface of the oil adding pipe 102, and a reverse fixed thread 105 is fixed on the lower surface of the fixed cover 104, the position, close to the middle, of the lower surface of the fixed cover 104; the number of the heat dissipation baffles 3 is two, and the two sides of the heat dissipation baffles 3 are fixedly provided with fixing blocks 301 at the inner surfaces of the internal ring 1 and the external cover 2; the number of the lubricating pipes 4 is two, and a lubricating spray head 401 is fixedly arranged on the outer surface of one side of each lubricating pipe 4, which is positioned on the outer surface of the built-in ring 1; the inner surface of the limiting block 5 is movably provided with balls 501 at positions close to the two sides.

It should be noted that, the utility model relates to an automatic aligning double-row deep groove ball bearing, when using, need to rotate the fixed cover 104 so that reverse fixed thread 105 and forward fixed thread 103 separate and take away fixed cover 104, need to pour lubricating oil into the lubricating pipe 4 through installing the oil adding pipe 102 on the oil adding hole 101 at this moment, then fix the fixed cover 104 on adding the oil pipe 102 fixedly, can install fixed object in the built-in ring 1 at this moment and install the external cover 2 surface on the object that needs to rotate, then can use this product, when the external cover 2 of this product rotates at a high speed, just can drive the ball 501 installed on the stopper 5 to rotate, lubricating sprinkler 401 will paint lubricating oil on ball 501 when ball 501 rotates, thereby prevent that built-in ball 501 can't obtain the replenishment of lubricating oil in time and lead to the efficiency of ball 501 to reduce by a wide margin, common double row deep groove ball bearing installs the baffle but the existence of baffle also directly leads to the unable discharge of heat that ball 501 produced when high-speed motion in order to prevent that external filth from contacting ball 501 on, so this finished product replaces heat baffle 3 with the baffle and also can be for ball 501 heat dissipation when preventing that external filth from contacting ball 501.
