Abstract
The utility model discloses a bearing heat abstractor for an air guide sleeve type electric motor, which aims to solve the problem that the initial electric motor cannot radiate the heat of a bearing on the other side of a fan. The bearing heat abstractor is characterized in that: a pedestal 2 is arranged on the electric motor 1; and the electric motor 1 is equipped with a fan 3. A fan guard 4 is arranged outside the fan 3. The fan 3 is driven to rotate when the electric motor 1 rotates; the fan 3 sucks the air from the outer side of the fan guard; the fan guard 4 blows the air via a radiating plate 5, thereby firstly radiating the heat of the electric motor. The air is re-collected by an air guide sleeve 6 after passing through the radiating plate 5; and the collected air passes though a bearing 7 so as to radiate the heat of the bearing 7 on the other side of the bearing. The bearing heat abstractor for the air guide sleeve type electric motor is simple and reliable to manufacture, highly low-cost, convenient for use, and easy to be popularized.
Description
Technical field
The utility model relates to a kind of device that the bearing of electrical motor fan opposite side is dispelled the heat with kuppe.
Background technology
For a long time, the radiator structure of motor all is that the fan that carries with motor dispels the heat.The fan that is driven self by the rotation of motor itself sucks cold wind, through fan guard cold air is blown over by fin then, takes away the heat that motor itself is produced.But this mode has following defective: promptly can only dispel the heat to motor itself and fan side bearing, because there is circulation of air in these places, but can not carry out active heat removal to the bearing of fan opposite side, cause the bearing temperature of fan opposite side to raise.And the rising of the temperature of bearing causes bearing internal lubrication oil thinning, the lubricant effect variation, and the speed that the lubricant effect variation can cause bearing temperature to raise is faster.If it is high-order that temperature keeps for a long time, will cause damage of bearings and motor reel to become curved.And both of these case all can cause the friction of the stator and the rotor of motor, makes the rapid rising of local temperature of motor stator and causes coil burnout, thereby motor is damaged.
Summary of the invention:
The goal of the invention of the utility model mainly is that the technical scheme through the following stated is achieved.At the electrical motor fan opposite side kuppe is installed, kuppe is concentrated the wind that passes through blade that fan produces again, passes through the bearing of fan opposite side then.Wherein porose on the kuppe, concentrate the cooling air of blowing over fan opposite side bearing to discharge through kuppe, thereby make the bearing of opposite side also can carry out heat radiation initiatively from the hole in the middle of the kuppe.Therefore the utility model has following advantage:
1, the bearing that has solved the electrical motor fan opposite side can not carry out active heat removal, and causes the high problem of this split bearing temperature.
2, because the bearing of fan opposite side can carry out active heat removal through the circulation of air, make the life-span of bearing prolong, prevent the damage of bearing, thereby prevent the stator and the friction rotor of motor.
Description of drawings
Accompanying drawing provides the structural representation and the operation principle of the water conservancy diversion bell-type bearing of motor heat abstractor of the utility model.
Embodiment
Through embodiment and combine accompanying drawing, the structure of the utility model is done further to describe below.
Embodiment: base 2 is arranged on motor 1, fan 3 is installed on motor, there is fan guard 4 fan 3 outsides.When motor rotates, drive fan and rotate.Fan sucks the cold air of outside; Discharge through fan guard 4; Fin 5 through motor dispels the heat to motor itself earlier; When air that fan is discharged from the heat radiator fins of motor through being regrouped by kuppe 6 again later, discharge in the hole in the middle of the kuppe then through bearing 7, thereby the bearing of accomplishing the fan opposite side dispels the heat.The arrow of drawing in the accompanying drawing refers to the path of air flow.Thereby make the utility model reach the purpose of aforementioned invention effectively.
Claims (2)
1. flow-guiding type bearing of motor heat abstractor, it includes motor (1), and fan (3) and fan guard (4) are arranged on the motor (1), it is characterized in that being equipped with on the motor (1) kuppe (6).
2. bearing of motor heat abstractor according to claim 1; It is characterized in that: kuppe (6) is installed in the opposite side of electrical motor fan, and drive fan (3) rotates and discharges through bearing (7) after the air that blows out via fan guard (4) regroups in the time of will being rotated by motor.
