Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a lightweight bearing. Background Art

[0002] A bearing is a mechanical element that supports and enables a rotating part to rotate on a fixed shaft. A bearing is usually composed of an inner ring, an outer ring, rolling elements, and a cage. The function of bearings is to reduce friction between mechanical parts, thereby reducing energy loss and extending the service life of mechanical parts. They are widely used in various mechanical equipment. Bearings are usually used in conjunction with bearing seats.

[0003] A lightweight bearing is a specially designed bearing that aims to reduce its weight and size while maintaining adequate load-bearing capacity and performance. To achieve lightweighting, manufacturers may use advanced materials, design and manufacturing processes, and optimize the structure to achieve lightweighting.

[0004] However, if the lightweight bearing needs to run continuously for a long time or bear high load, the lightweight bearing will accumulate a lot of heat. The lightweight bearing itself is made of light materials, which makes it easy to deform or damage, thus affecting its normal load-bearing capacity and life. To this end, we propose a lightweight bearing. Utility Model Content

[0019] See also Figure 1-Figure 4A lightweight bearing shown in the figure comprises an outer ring 2, an inner ring 4, an annular groove 12 provided on the inner ring surface of the outer ring 2, and two protective pads 3 installed between the outer ring 2 and the inner ring 4. The outer ring 2 is hollowed out inside, and a plurality of heat sinks 9 are fixedly connected to the inner wall of the outer ring 2. A water cooling pipe 8 and a water cooling pipe 11 are fixedly penetrated through the inner walls of the plurality of heat sinks 9. An arc-shaped pipe 6 is connected between the outer walls of the water cooling pipe 8 and the water cooling pipe 11. The outer walls of the water cooling pipe 8 and the water cooling pipe 11 are respectively connected with a water outlet pipe 7 and a water inlet pipe 5. The water outlet pipe 7 and the water inlet pipe 5 are respectively fixedly penetrated through the two side walls of the outer ring 2, and a protective piece is provided at one end of the water outlet pipe 7 and the water inlet pipe 5 located at the outer ring 2.

[0020] See also Figure 1 , Figure 2 and Figure 4 In the figure, the protective member includes two pipe covers 1, and the two pipe covers 1 are respectively threadedly sleeved on one end of the water outlet pipe 7 and the water inlet pipe 5 located at the outer circle 2.

[0021] See also Figure 4 In the figure, a plurality of anti-skid grooves 14 are provided on the outer wall of the tube cover 1. The plurality of anti-skid grooves 14 are provided on the outer wall of the tube cover 1 in a central annular array around the tube cover 1. By providing the anti-skid grooves 14, an anti-skid effect can be achieved when the tube cover 1 is rotated.

[0022] See also Figure 2 and Figure 4 In the figure, multiple heat sinks 9 are arranged in a circular array around the center of the outer ring 2; the multiple heat sinks 9 are evenly distributed, which not only improves the heat dissipation effect, but also improves the overall structural strength of the outer ring 2.

[0023] See also Figure 2 and Figure 4 In the figure, multiple heat sinks 9 are provided with arc grooves 10 at the center end corresponding to the outer ring 2, and the inner wall of the arc groove 10 is in contact with the arched surface inside the outer ring 2; the arched surface inside the outer ring 2 is mainly caused by the annular groove 12 on the inner ring surface of the outer ring 2, and the annular groove 12 is mainly used for the rolling of the ball on the inner ring surface of the outer ring 2. The setting of the arc groove 10 can increase the contact area between the heat sink 9 and the inner wall of the outer ring 2, and further improve the heat dissipation effect.

[0024] See also Figure 3 In the figure, both side walls of the outer ring 2 are provided with holes 13, and the outlet pipe 7 and the inlet pipe 5 are respectively matched with the shapes of the two holes 13; by providing the holes 13, it is convenient for the outlet pipe 7 and the inlet pipe 5 to pass through the outer ring 2.

[0025] Working principle: After the outer ring 2 is installed on the inner side of the bearing seat, the two pipe covers 1 are rotated outward in turn, and then the water supply pipelines of the water circulation system are connected to the water outlet pipe 7 and the water inlet pipe 5 respectively (the water circulation system is a well-known existing technology, mainly composed of a water pump, a water tank and several water supply pipelines). When the water circulation system is operating, the cooling water can enter the interior of the water-cooling tube 2 11 along the water inlet pipe 5, and then enter the interior of the water-cooling tube 1 8 along the arc tube 6, and finally be discharged along the water outlet pipe 7, forming a circulation flow of cooling water in the water-cooling tube 2 11, the arc tube 6, the water-cooling tube 1 8 and the water outlet pipe 7.

[0026] When the lightweight bearing needs to operate continuously for a long time or bear high load, the heat generated by the lightweight bearing can be taken away by the circulating flow of cooling water. At the same time, the multiple heat sinks 9 can also absorb the heat of the lightweight bearing and transfer the heat to the water-cooling pipe 1 8 and the water-cooling pipe 2 11. The heat can be taken away by the cooling water again, which can have a good heat dissipation effect on the lightweight bearing, avoid deformation or damage of the lightweight bearing due to high temperature, and extend its normal load-bearing capacity and life.
