Description
Technical Field
[0001] The utility model belongs to the technical field of guide plates, and in particular relates to a guide plate installed on a front end cover of a motor. Background Art
[0002] As the ambient temperature rises in summer, the temperature of motor bearings also generally rises. The temperature of some motor front bearings can reach over 80 degrees. Long-term high-temperature operation of motor bearings can easily lead to aging of lubricating oil and affect the life of bearings. At present, the heat dissipation of motor front bearings is only achieved through the contact between the front cover and the air, which is difficult to meet the cooling requirements of bearings. For this reason, we propose a guide plate installed on the front cover of the motor to solve this problem. Utility Model Content

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a motor front end cover is installed with a guide plate, comprising a motor body and an outer guide cover plate, the front end of the motor body is provided with a front bearing oil cup cover, the outer guide cover plate is penetrated with screw holes and through holes, the front end cover and the front bearing oil cup cover of the motor body are screwed to the screw holes on the outer guide cover plate through bolts, a connecting rod is provided inside the outer guide cover plate, one end of the connecting rod is welded to the inner guide cover plate, and a wind hole is penetrated in the middle position of the inner guide cover plate.
[0005] The beneficial effects of the utility model are as follows: when the motor is running, a part of the airflow blown by the fan in the wind cover is blown out from the gap between the front end of the wind cover and the heat sink, and flows straight forward. This part of the airflow first enters the inner side of the inner guide cover plate, and flows and gathers toward the position of the wind hole. By utilizing this part of the airflow, the airflow volume on the outside of the front end cover and the front bearing oil cup cover is increased, thereby improving the convection heat exchange efficiency and the heat dissipation air volume between the air and the front end cover and the front bearing oil cup cover, thereby effectively reducing the temperature of the front end bearing, effectively avoiding overheating of the motor bearing and rapid aging of the bearing oil, extending the bearing oil replacement cycle, and increasing the service life of the bearing.
[0006] To provide air flow for cooling of the front bearing:
[0007] As a further improvement of the above technical solution: a wind shield is provided at the rear end of the motor body.
[0008] The beneficial effect of this improvement is that a cooling fan is installed inside the wind cover. When the motor is running, part of the airflow blown out by the fan in the wind cover is blown out from the gap between the front end of the wind cover and the heat sink, flowing straight forward to provide airflow for cooling the front bearing.
[0009] To assist in cooling the motor body:
[0010] As a further improvement of the above technical solution: a heat sink is provided on the outer side of the motor body.
[0011] The beneficial effect of this improvement is that the heat sink is used to assist in heat dissipation of the motor body.
[0012] In order to improve the structural strength of the outer fairing:
[0013] As a further improvement of the above technical solution: a reinforcing ring plate is provided on the outer side of the outer air guide cover plate, and reinforcing ribs are welded between the reinforcing ring plate and the outer air guide cover plate.
[0014] The beneficial effect of this improvement is that a reinforcing ring plate is provided on the outer side of the outer air guide cover plate, and reinforcing ribs are welded between the reinforcing ring plate and the outer air guide cover plate, thereby greatly improving the structural strength of the outer air guide cover plate and reducing its vibration amplitude during motor operation, thereby reducing noise.
[0015] To direct the airflow:
[0016] As a further improvement of the above technical solution: an arc-shaped ring plate is provided at one end of the inner air guide plate.
[0017] The beneficial effects of this improvement are as follows: the setting of the arc-shaped ring plate, on the one hand, plays the role of gathering the airflow blown out of the wind hood to the inner side of the inner guide cover plate; on the other hand, after the airflow enters the space between the outer guide cover plate and the inner guide cover plate through the wind holes, it first flows upward and then backward, and finally flows out to the surroundings under the guidance of the arc-shaped ring plate, without affecting the airflow blown out of the wind hood.

The front end cover of the motor body 1 and the front bearing oil cup cover 4 are screwed with the screw holes 12 on the outer guide cover plate 5 through bolts 13. A connecting rod 8 is provided inside the outer guide cover plate 5, and one end of the connecting rod 8 is welded to the inner guide cover plate 9. The middle position of the inner guide cover plate 9 is penetrated with a wind hole 10.
[0027] When the motor is running, part of the airflow blown out by the fan in the wind cover 2 is blown out from the gap between the front end of the wind cover 2 and the heat sink 3, and flows straight forward. This part of the airflow first enters the inner side of the inner guide cover plate 9, and flows and gathers toward the position of the wind hole 10.

[0028] A wind shield 2 is provided at the rear end of the motor body 1 .
[0029] A cooling fan is installed inside the wind cover 2. When the motor is running, part of the airflow blown by the fan in the wind cover 2 is blown out from the gap between the front end of the wind cover 2 and the heat sink 3, flowing straight forward to provide airflow for cooling the front bearing.
[0030] A heat sink 3 is disposed on the outer side of the motor body 1 .
[0031] The heat sink 3 is used to assist the motor body 1 in dissipating heat.

[0033] A reinforcing ring plate 6 is provided on the outer side of the outer air guide plate 5, and reinforcing ribs 7 are welded between the reinforcing ring plate 6 and the outer air guide plate 5, thereby greatly improving the structural strength of the outer air guide plate 5 and reducing its vibration amplitude during the operation of the motor, thereby reducing noise.
[0034] An arc-shaped ring plate 11 is provided at one end of the inner air guide plate 9 .
[0035] The setting of the arc-shaped ring plate 11, on the one hand, plays the role of gathering the airflow blown out of the wind hood 2 to the inner side of the inner guide cover plate 9; on the other hand, after the airflow enters the space between the outer guide cover plate 5 and the inner guide cover plate 9 through the air hole 10, it first flows upward and then backward, and finally flows out to the surroundings under the guidance of the arc-shaped ring plate 11, without affecting the airflow blown out of the wind hood 2.
[0036] Working principle and use process of the utility model: For conventional motors, the front bearing oil cup cover 4 at the front end is usually directly connected to the front end cover of the motor by bolts.
