Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pump products in which a motor adopts internal circulation of coolant for heat dissipation, and in particular to a bearing seat that is easy to dissipate heat. Background Art
[0002] In pump products with a coolant internal circulation structure, the motor is surrounded by coolant, and the circulation of coolant can achieve heat exchange in the motor, thus achieving the purpose of heat dissipation in the motor. The motor bearing seat is also inevitably surrounded by coolant, so how to achieve efficient heat dissipation of the bearing is also an inevitable issue.
[0003] like Figure 1 and Figure 2 As shown, the lower connecting plate and the upper connecting plate of the conventional bearing seat are connected as a whole, and the bearing mounting body is surrounded by the lower connecting plate. When dissipating heat, the coolant inside the motor cannot contact the bearing mounting body, and the heat dissipation of the bearing inside the bearing seat can only be achieved by the air inside the motor cavity. However, when the motor adopts a coolant internal circulation structure, the motor is surrounded by coolant and it is difficult to achieve heat exchange with the air, and the heat dissipation capacity is limited. When the bearing runs continuously for a long time, it is easy to have problems such as overheating, accelerated loss of lubricating grease, and shortened bearing life. Utility Model Content
[0004] The utility model aims to remedy the defects of the prior art and provide a bearing seat that is easy to dissipate heat.
[0005] The utility model is realized by the following technical solutions:
[0006] A bearing seat that is easy to dissipate heat, includes a bearing mounting body, an axial bearing mounting hole is opened on the bearing mounting body, an upper connecting plate is connected to the upper part of the outer wall of the bearing mounting body, and a lower connecting plate is connected to the bottom end of the outer wall of the bearing mounting body. The upper connecting plate and the lower connecting plate are both circular plates, and the outer diameter of the upper connecting plate is larger than the outer diameter of the lower connecting plate. A plurality of heat dissipation ribs are evenly distributed between the lower side surface of the upper connecting plate, the lower outer wall of the bearing mounting body and the upper side surface of the lower connecting plate, and an inclined guide plate is fixed to the outer end of each of the heat dissipation ribs.
[0007] The bearing mounting body is a cylinder, and the bearing mounting hole is a stepped hole.
[0008] The upper end of the guide plate is connected to the outer end surface of the upper connecting plate, and the lower end of the guide plate is connected to the outer end surface of the lower connecting plate.
[0009] A plurality of supporting ribs are evenly distributed between the upper side surface of the upper connecting plate and the upper outer side surface of the bearing mounting body.
[0010] The advantages of the utility model are as follows: the utility model adds a heat dissipation rib plate between the lower connecting plate and the upper connecting plate of the bearing seat, and when the coolant in the motor cavity flows, it will enter the cavity between the two adjacent heat dissipation rib plates, so that the lower part of the bearing mounting body is directly in contact with the coolant, the heat of the bearing is transferred to the bearing seat, and the flow of the coolant takes away the heat of the bearing seat, thereby increasing the contact area with the coolant, improving the cooling effect, and achieving the effect of fast heat dissipation of the bearing;
[0011] The utility model is provided with a guide plate on the outer wall of the bearing seat, which improves the heat dissipation effect of the bearing and the bearing seat without changing the flow form of the motor coolant and affecting the heat dissipation effect of the motor;
[0012] The utility model realizes efficient heat dissipation of the bearing and the bearing seat without changing the heat dissipation mode of the motor, has a simple structure, does not increase other parts, is convenient for assembling the water pump, and has low cost.

[0018] like Figure 3 As shown, a bearing seat that is easy to dissipate heat includes a bearing mounting body 6, an axial bearing mounting hole 7 is opened on the bearing mounting body 6, an upper connecting plate 8 is connected to the upper part of the outer wall of the bearing mounting body 6, and a lower connecting plate 9 is connected to the bottom end of the outer wall of the bearing mounting body 6. The upper connecting plate 8 and the lower connecting plate 9 are both circular plates, and the outer diameter of the upper connecting plate 8 is larger than the outer diameter of the lower connecting plate 9. A plurality of heat dissipation ribs 10 are evenly distributed between the lower side surface of the upper connecting plate 8, the lower outer wall of the bearing mounting body 6 and the upper side surface of the lower connecting plate 9, and an inclined guide plate 11 is fixed to the outer end of each of the heat dissipation ribs 10. There is a cavity between adjacent heat dissipation ribs 10. When the coolant in the inner cavity of the motor flows, the coolant can enter the cavity to drive the heat of the bearing seat. The guide plate achieves the effect of guiding flow, so that the flow direction of the coolant in the inner cavity of the motor remains unchanged, and will not affect the heat dissipation of the motor.
[0019] The bearing mounting body 6 is a cylinder, and the bearing mounting hole 7 is a stepped hole.
[0020] The upper end of the guide plate 11 is connected to the outer end surface of the upper connecting plate 8 , and the lower end of the guide plate 11 is connected to the outer end surface of the lower connecting plate 9 .
[0021] A plurality of supporting ribs 12 are evenly distributed between the upper side surface of the upper connecting plate 8 and the upper outer side surface of the bearing mounting body 6 to play a supporting role.
[0022] In pump products with a coolant internal circulation structure for the motor, the motor is surrounded by coolant on the outside, and has an outer sleeve 1 and a water distribution barrel 2 on the outside. The coolant circulates through the circulating impeller 3 at the bottom. When the liquid flows through the surface of the casing 4, it takes away the heat from the motor, thereby achieving the purpose of cooling the motor.
[0023] The utility model redesigns the outer wall of the bearing seat 5 so that the outer wall of the bearing seat 5 is in direct contact with the coolant. When the coolant flows, it takes away the heat of the bearing, thereby achieving heat dissipation of the bearing.
[0024] The heat dissipation rib plate 10 is designed to allow the bearing seat 5 to have a larger contact area with the coolant, thereby increasing the heat dissipation area and achieving rapid heat dissipation;
[0025] The guide plate 11 is designed so that the flow pattern of the coolant will not affect the cooling effect of the motor due to the change of the structure.
