According to the scheme, the air flow blown to the front end bearing of the motor from the rear end of the motor can be guided to the front end bearing of the motor by adding the air guide cover, the front end bearing is cooled, the existing structure of the motor is not required to be changed, the front end bearing of the motor can be cooled, and the structure is simple and convenient to install.

Description

Motor front axle cooling device

Technical Field

The utility model relates to a motor field specifically is a motor front axle cooling device.

Background

In many industrial environments, motors can be used, and front and rear bearings of the motors are easy to generate heat when the motors run, so that the service lives of the motors are influenced, and the motors are easy to overheat and damage.

At present, only the fan is arranged at the rear bearing of the motor due to the structural reason of the motor, and the fan cannot be arranged at the front bearing. And the motor front bearing is generally opposite to the equipment driven by the motor lock, and if the temperature of the equipment is higher, the motor front bearing opposite to the equipment is more easily damaged by overheating.

In the prior art, a fan is arranged at the rear end of the motor and blows air flow from the rear end to the front end of the motor along the gap between the radiating fins on the motor shell. However, the air flow can only pass through the periphery of the motor shell and can not reach the front end bearing of the motor, so that heat at the front end bearing of the motor is easy to accumulate to cause overheating damage of the front end bearing of the motor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a carry out radiating motor front axle cooling device to motor front end bearing under the condition that does not change the structure of motor itself.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a motor front axle cooling device, is the motor rear end fan from motor rear end to motor front end including the direction of blowing, and the motor rear end fan is enclosed to the fan housing behind the motor, and the air outlet of fan housing links up in the tip of motor fin behind the motor, and the motor front end is provided with the guide wind scooper that the direction of guide air current made it blow to motor front end bearing.

According to the scheme, the air flow blown to the front end bearing of the motor from the rear end of the motor can be guided to the front end bearing of the motor by adding the air guide cover, the front end bearing is cooled, the existing structure of the motor is not required to be changed, the front end bearing of the motor can be cooled, and the structure is simple and convenient to install.

Detailed Description

The utility model provides a motor front axle cooling device, is the motor rear end fan from motor rear end to motor front end including the direction of blowing, and motor rear end fan is enclosed to fan housing 10 behind the motor, and the air outlet of fan housing 10 links up in the tip of motor fin 1 behind the motor, and the motor front end is provided with guide wind scooper 20 that the direction of guide air current made its blow to motor front end bearing.

In the scheme, the fan at the rear end of the motor forms airflow from the rear end of the motor to the front end of the motor, the airflow blows in the gap between the radiating fins 1 of the motor and blows towards the front end of the motor along the gap due to the blocking of the rear end of the motor and the rear fan cover 10 of the motor, the airflow blows in the wind scooper 20 from the end gap of the radiating fins 1, and is guided by the wind scooper 20 to finally blow towards and dissipate heat of the bearing at the front end of the motor.

The wind scooper 20 comprises a front plate 21 with a plate surface perpendicular to the axial core of the motor rotating shaft 2, and the outer edge of the front plate is connected with an arc-shaped coaming 22 with a plate surface parallel to the axial core of the motor rotating shaft 2. The air guiding cover 20 changes the direction of the air flow from horizontal to vertical so as to blow the air flow to the front end bearing of the motor.

The wind scooper 20 is located above the front end of the motor, the front plate 21 is semi-circular, and the rear end of the arc coaming 22 is enclosed at the upper edge of the front end of the radiating fin 1 to form the wind inlet of the wind scooper 20. The inner circle of the semi-circular front plate 21 avoids the motor rotating shaft 2, the outer circle of the semi-circular front plate conforms to the circumferential profile of the motor, so that the wind scooper 20 is more attached to the appearance of the motor, other parts are not easily interfered while the installation is convenient, the motor base below the motor blocks the wind scooper 20 not to be easily installed, the wind scooper 20 is installed above the motor, the installation is convenient, the state of the wind scooper 20 can be directly observed, and once the wind scooper 20 is damaged or inclined, the wind scooper 20 can be timely found and processed.

The shroud 22 is bolted to the motor housing. The motor shell is provided with corresponding bolt holes, the wind scooper 20 is low in weight and low in fastening requirement, and therefore the coaming 22 and the motor shell are connected through bolts, and the wind scooper is convenient and quick to disassemble and assemble.
