Description
Technical field
The utility model relates to a kind of end cap, and more particularly, it relates to a kind of electric motor end cap.
Background technology
Conventional motors end cap adopts the metals such as cast iron to make, lid is made up of the base plate of integrative-structure and annular side plate, side plate offers louvre, base plate is also provided with louvre, base plate and side plate are all nonocclusive, so dust or other foreign material are made to enter motor, impact is had on the bearing at two on motor shaft, stators and rotators is caused to grind heating mutually after bearing is bad, and then burn out coil, affect the useful life of motor, and electric motor end cap is without radiating ribs, motor temperature in the situation of working long hours is very high, only rely on the radiating ribs on motor housing, the heat of motor internal is not easy to distribute, the part long-term work of motor internal in high temperature environments, useful life can shorten the machine operation time greatly.
At present, the application number on market be 201320663010.4 Chinese patent disclose a kind of electric motor end cap, its outer face is provided with radiating ribs and reinforcement.Although this electric motor end cap can reinforcement heat radiation to a certain degree and blocks dust or other foreign material can enter motor, stuffy in shell, can not effectively heat be distributed.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of good heat dissipation effect, dust-proof electric motor end cap.
For achieving the above object, the utility model provides following technical scheme:
A kind of electric motor end cap, comprise the lid of base plate and annular side plate composition, described base plate medial center is provided with dead eye, described base plate is circumferentially evenly provided with louvre, radiating ribs is provided with between described adjacent heat radiation hole, described louvre is provided with venting ring, and the sidewall that described venting ring is adjacent with louvre is provided with ventilation hole.
Preferably, filter screen is provided with in described venting ring.
Preferably, described radiating ribs is connected with annular side plate with dead eye, and described base plate, annular side plate, radiating ribs and venting ring are formed in one.
Preferably, described venting ring is arranged with dead eye is concentric.
Compared with prior art, the utility model has the advantage of: on the base plate of end cap, be circumferentially evenly provided with louvre, hot gas in shell and outside air can circulate by louvre, greatly strengthen the radiating effect of motor, radiating ribs is provided with between described adjacent heat radiation hole, radiating ribs not only increases overall construction intensity, and there is certain radiating effect, described louvre is provided with venting ring, the sidewall that described venting ring is adjacent with louvre is provided with ventilation hole, described louvre is connected with ventilation hole, in shell, hot gas all first enters in venting ring by ventilation hole, and venting ring is connected with radiating ribs, in venting ring, a heat part is absorbed by radiating ribs and outwardly exhales, in venting ring, hot gas is dispersed into the external world by louvre again, and ventilation hole is arranged on the sidewall adjacent with louvre, add contacting of air-flow and base plate and venting ring, and extraneous dust and foreign material are when entering in motor from louvre, stopped by venting ring, the utility model has good radiating effect, and extraneous dust and foreign material can be stoped to enter in motor.
