Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and more specifically, to a drive shaft bearing housing with heat dissipation channels. Background Technology

[0002] Bearing housings are key components in mechanical transmissions that support bearings, fix shaft components, and bear loads. They are widely used in equipment such as motors, fans, machine tools, and automobiles.

[0003] Currently, drive shaft bearing housings typically employ an integral structure, relying primarily on natural convection and the housing's own metal conduction for heat dissipation. However, during actual operation, the high-speed rotation of the drive shaft generates significant frictional heat between the bearing and journal, and between the rolling elements and raceways within the bearing. Coupled with the complex and variable working environment, the low heat dissipation efficiency of traditional bearing housings becomes increasingly apparent. This continuous accumulation of heat leads to a sharp increase in the operating temperature of the bearing housing and the bearing itself, causing a decrease in lubricating oil viscosity and deterioration in lubrication performance. This, in turn, accelerates bearing wear, reduces bearing lifespan, and in severe cases, can even cause serious malfunctions such as bearing seizure and drive shaft breakage, affecting the stable operation of the entire mechanical system. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drive shaft bearing housing with heat dissipation channels.

A fan is fixedly installed at the end of the output shaft of the motor.

[0007] As a preferred embodiment of this utility model, two first connecting blocks are fixedly installed on the lower base, and two second connecting blocks are fixedly installed on the upper base, with the tops of the two first connecting blocks abutting against the bottoms of the opposite second connecting blocks.

[0008] As a preferred embodiment of the present invention, a first fixing screw is provided through between the first connecting block and the opposite second connecting block, and a nut is threaded onto the first fixing screw, the top of the nut abutting against the bottom of the first connecting block.

[0009] As a preferred technical solution of this utility model, the lower base is threaded with a plurality of second fixing screws, and the plurality of second fixing screws all penetrate the arc-shaped iron sheet and fix it.

[0010] As a preferred embodiment of this utility model, a baffle is fixedly installed on the top of the mounting plate, and the baffle is located directly above the motor and the fan.

[0021] Please see Figure 1-4 Structural diagram; the present invention provides the following technical solution:

[0022] Specifically, it refers to a drive shaft bearing housing with a heat dissipation channel, including a lower base 1 and an upper base 2. The lower base 1 is provided with two reinforcing ribs 7. A mounting plate 10 is fixedly installed on the lower base 1. Two mounting holes 8 are opened through the lower base 1. A heat dissipation mechanism is provided between the lower base 1 and the mounting plate 10. The heat dissipation mechanism includes an arc-shaped iron plate 15 provided on the lower base 1. Multiple heat dissipation fins 16 are fixedly installed on the arc-shaped iron plate 15. A mounting seat 12 is fixedly installed on the top of the mounting plate 10. A motor 13 is fixedly installed on the top of the mounting seat 12. A fan 14 is fixedly installed at the end of the output shaft of the motor 13. A baffle 11 is fixedly installed on the top of the mounting plate 10. The baffle 11 is located directly above the motor 13 and the fan 14. Multiple second fixing screws 17 are threadedly connected to the lower base 1. The multiple second fixing screws 17 all pass through the arc-shaped iron plate 15 and fix it.

[0023] This invention, through the design of a heat dissipation mechanism, can improve the heat dissipation effect of the bearing and rotating shaft during operation, thereby extending the service life of the bearing.

[0024] Two first connecting blocks 3 are fixedly installed on the lower base 1, and two second connecting blocks 4 are fixedly installed on the upper base 2. The tops of the two first connecting blocks 3 abut against the bottoms of the opposite second connecting blocks 4. A first fixing screw 5 is provided through between the first connecting blocks 3 and the opposite second connecting blocks 4. A nut 6 is threadedly connected to the first fixing screw 5, and the top of the nut 6 abuts against the bottom of the first connecting block 3.

[0025] The arrangement of the first connecting block 3, the second connecting block 4, the first fixing screw 5, and the nut 6 allows the operator to easily remove the upper base 2 from the lower base 1, thereby facilitating the operator to disassemble and replace the bearing installed between the lower base 1 and the upper base 2.

[0026] Multiple heat dissipation holes 9 are evenly arranged on the upper base 2.

[0027] This invention improves the heat dissipation of the bearing by setting multiple heat dissipation holes 9 on the upper base 2, so that it can maintain a low temperature during operation.

[0028] The working principle of the drive shaft bearing housing with heat dissipation channel provided by this utility model is as follows:

[0029] Working principle:

[0030] Equipment operation process

[0031] When the drive shaft is working, the motor 13 is turned on first, and the fan 14 starts to rotate, generating forced airflow. The airflow is guided by the baffle 11 and flows through the bearing area near the mounting plate 10, carrying away the heat generated by friction. The heat is transferred to the heat sink 16 through the arc-shaped iron plate 15, and further dissipated through air convection. The heat dissipation holes 9 of the upper base 2 accelerate the discharge of internal hot air, forming a heat dissipation channel.

[0032] Drive shaft operation

[0033] When the drive shaft rotates at high speed, the bearing supports the shaft system and bears the load. The heat generated by friction is dissipated through the following path: bearing → arc-shaped iron plate 15 → heat sink 16 → air convection.

[0034] Hot air inside the bearing cavity → heat dissipation hole 9 → external environment.

[0035] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
