Abstract
The invention discloses a motor end cap, and particularly relates to an oil-filling end cap with oil filling holes and sector cavities. The oil-filling end cap comprises a motor end cap body fixed onto a motor body and connected with a motor bearing block, circular oil-filling holes are formed on a ring surface of the motor end cap body, cylindrical oil-filling cavities are formed below the oil-filling holes and communicated with the same, and the sector cavities communicated with the oil-filling cavities are arranged at the joint between the inner end surface of the motor end cap body and the motor bearing block. The oil-filling end cap has the advantages that by the aid of the sector cavities communicated with the oil-filling cavities, the contact area between the sector cavities and the bearing block is larger, filled lubricating oil is distributed uniformly, good lubricating effect is achieved, and safety running and late maintenance of motors are facilitated.
Description
Technical field
The present invention relates to a kind of electric motor end cap, specifically, relate to a kind of fan-shaped chamber oiling end cap with oil filler point.
Background technology
Usually, electric motor end cap also plays the effect of fixed electrical machinery bearing not only for the protection of motor.During the motor long-time running, the lubricating oil meeting slow consumption on the motor bearings until losing lubrication, therefore needs regularly carry out oil injecting lubricating to the motor internal motor bearings, guarantees that motor can safe operation.
For making things convenient for the regular oiling of motor bearings, electric motor end cap generally all has oil filler point, by oil filler point connection shaft bearing and end cap, play the effect of intermittent oiling bearing maintenance motor, but the oil filler point of prior motor end cap mostly is cylindrical, during oiling, lubricating oil flows into bearing pedestal straight from the electric motor end cap oil filler point, lubricating oil distributes very inhomogeneous, and lubricant effect is not good enough, is unfavorable for safe operation and the later maintenance work of motor.
Summary of the invention
The present invention is directed to the shortcoming of existing motor oiling inequality, provide a kind of simple in structure, the fan-shaped chamber oiling of the uniform motor of oiling end cap.
Technical scheme of the present invention is: the fan-shaped chamber oiling of a kind of motor end cap, it is characterized in that: comprise the electric motor end cap that is fixed in the motor body and links to each other with the motor shaft bearing, described electric motor end cap anchor ring is provided with circular oil filler point, the oil filler point bottom is and the cylindrical oiling chamber of its perforation that described electric motor end cap inner face and motor shaft bearing junction are provided with the fan-shaped chamber that connects with the oiling chamber.
Preferably, described oil filler point has two.
Preferably, described oil filler point is provided with seal cover, and seal cover is connected by engage thread with oil filler point.
Preferably, described electric motor end cap is provided with the screw fixing with body.
The present invention's beneficial effect compared with prior art is:
The fan-shaped chamber oiling of motor of the present invention end cap adopts the fan-shaped chamber device that connects with the oiling chamber, flowing into bearing pedestal with previous lubricating oil straight from the electric motor end cap oil filler point compares, the contact area of fan-shaped chamber and bearing pedestal is bigger, injection lubricating oil is evenly distributed, good lubricant effect be can reach, safe operation and the later maintenance work of motor are conducive to.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 1-electric motor end cap, 2-oil filler point, 3-oiling chamber, 4-fan-shaped chamber, 5-screw
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention:
Referring to Fig. 1, the fan-shaped chamber oiling of a kind of motor end cap, comprise the electric motor end cap 1 that is fixed in the motor body and links to each other with the motor shaft bearing, electric motor end cap 1 anchor ring is provided with two circular oil filler points 2, oil filler point 2 bottoms are and the cylindrical oiling chamber 3 of its perforation, and electric motor end cap 1 inner face and motor shaft bearing junction are provided with the fan-shaped chamber 4 that connects with oiling chamber 3, and oil filler point 2 is provided with seal cover, seal cover and oil filler point 2 are connected by engage thread, and electric motor end cap 1 is provided with the screw 5 fixing with body.
During oiling, lubricating oil flows into oiling chamber 3 and the fan-shaped chamber 4 successively from oil filler point 2, along with fan-shaped chamber face flow into the motor shaft bearing, the running that does not stop because of motor, the lubricating oil that injects will spread upon uniformly rotation motor bearings on, fan-shaped chamber 4 designs that electric motor end cap 1 adopts the oiling chamber to connect, fan-shaped chamber 4 is bigger with the contact area of motor shaft bearing, injecting lubricating oil can be evenly distributed with the motor bearings rotation, the lubricant effect ideal is for safe operation and the later maintenance work of motor provides safeguard.
