Description
Technical field
The invention belongs to electrical equipment manufacturing technology field, be specifically related to a kind of flabellum mounting structure and there is the ceiling fan of this flabellum mounting structure.
Background technique
Ceiling fan comprises flange, motor shaft, motor, flabellum, and wherein motor, flabellum are installed on motor shaft, and motor shaft utilizes flange to be connected Yu Diao Wu, thus are fixedly installed on ceiling board.In traditional ceiling fan, flabellum is directly installed on housing, which results in following shortcoming: because the quantity of different client to flabellum has different requirements (such as say and require four flabellums or five flabellums), and the housing of motor cannot meet the requirement of installing different flabellum simultaneously, therefore can only could assembling shell and flabellum after receiving concrete order, and motor is when not holder housing, dependence test cannot be carried out, that is, to only have etc. after receiving concrete order and just can carry out last assembling and the dependence test of motor, and the test of motor needs the longer time, delaying of production waiting will be caused like this, client is difficult to satisfied.
Summary of the invention
The object of the invention is to propose that a kind of compatibility is strong, the flabellum mounting structure that can arrange production flexibly and the ceiling fan with this flabellum mounting structure.
Flabellum mounting structure of the present invention comprises the lower end cap of flabellum, leaf fork and motor, and described leaf forked cover is removably installed on lower end cap, and described flabellum is fixedly connected with leaf forked cover.
Ceiling fan of the present invention comprises motor shaft, motor, flabellum and flange, described motor is arranged on motor shaft, described flabellum is installed on motor, described motor shaft and Flange joint are fixed, it is characterized in that described motor is made up of upper end cap, lower end cap, leaf forked cover, stator and permanent magnet, described upper end cap and lower end cap fasten and form housing, and described stator is positioned at housing, and be fixedly connected with motor shaft, described permanent magnet is fixed in housing; Described leaf forked cover is removably installed on lower end cap, and described flabellum is fixedly connected with leaf forked cover.
Above-mentioned housing and permanent magnet constitute can the rotor of motor shaft and stator rotation relatively.Owing to have employed above-mentioned flabellum mounting structure (namely having increased demountable leaf forked cover newly), motor can assemble and test by people in advance, after receiving concrete order, only need according to the requirement of order, suitable leaf forked cover to be assembled on lower end cap, refill and join flabellum, namely when last assembling, without the need to carrying out assembling and the test of motor again, so just greatly save the time, improve working efficiency.People can design quantity installed by different leaf forks requirement with satisfied different flabellum, improve compatibility.
Further, described leaf forked cover is provided with the bolt hole for fixing flabellum, and the position of the bolt hole of the corresponding leaf forked cover of described lower end cap is closed.In traditional flabellum assembly process, employ long bolt because of careless sometimes, with the component contact such as the stator of motor in the housing that bolt will be caused like this to stretch to motor, cause motor damage.The Position Design of the bolt hole of corresponding for end cap leaf forked cover is closed by the present invention, thoroughly avoids bolt and stretches to problem in electric machine casing, improve Security.
Further, described lower end cap and leaf forked cover are provided with the buckle cooperatively interacted.Above-mentioned buckle assists the construction bolt of leaf forked cover to define protection to leaf forked cover, can prevent leaf forked cover from rotating relative to lower end cap, avoid the problem that leaf forked cover comes off from lower end cap.
Specifically, described buckle is made up of the flanging protruding from lower end cap bottom surface and the nib that is positioned at leaf forked cover edge, and the direction of above-mentioned flanging can toward the center of lower end cap, also can be tangent with the circumferencial direction of lower end cap.When installing leaf forked cover, the nib at leaf forked cover edge snaps in the gap between flanging and lower end cap bottom surface, thus is formed fixing.
Further, described flange comprises flange body, and described flange body is provided with screw and a through hole, and described through hole has part to be communicated with screw; Described through hole is installed with fixing pin, and the sidepiece of described fixing pin is provided with resistance and turns plane, and the resistance of described fixing pin turns plane towards screw direction has part to be positioned at screw; The top of described motor shaft is provided with outside thread, and the sidepiece on described motor shaft top is provided with fixed pan, and it is relative that the fixed pan of described motor shaft and the resistance of fixing pin turn plane.
Traditional motor shaft utilizes screw-thread fit and flange to fix, for preventing in electric fan working procedure, motor shaft rotates relative to flange and causes motor shaft solid failure, people have installed fixing pin in the side of flange, by fixing pin through flange but the front end of fixing pin is pressed on motor shaft, the pressure utilizing fixing pin to put on motor shaft side rotates to stop motor shaft.But in use, above-mentioned fixed structure is still difficult to avoid motor shaft to rotate relative to flange.In the present invention, under the prerequisite of not installing fixing pin, first by motor shaft and Flange joint, and regulate motor shaft to screw in the degree of depth of flange screw, make it meet the requirement of specific product; And then fixing pin inserted and is fixed in the through hole of flange, because the fixed pan of motor shaft and the resistance of fixing pin turn plane, therefore after installing, the resistance that motor shaft will be subject to fixing pin when flange rotates turns the stop of plane, motor shaft cannot be rotated relative to flange, ensure the reliably fixing of motor shaft and flange.
Further, described through hole is orthogonal with screw, and the sidewall of described screw is provided with auxiliary fixing threaded hole, is provided with auxiliary set screw in described auxiliary fixing threaded hole.Like this can when fixing pin and motor shaft size to be fixed, the surface of contact making the resistance of fixing pin turn the fixed pan of plane and motor shaft connects larger, and resistance turns better effects if.In addition, auxiliary set screw can clamping motor axle, the further rotation of prevention motor shaft.
Further, described through hole is arranged at the bottom of flange body, and fixing pin can be made like this closer to the upper end of motor shaft, even if the degree of depth that motor shaft screws in flange screw is less, also can prevent motor shaft from rotating relative to flange.
Further, described permanent magnet is fixed on the inwall of housing, described housing internal fixtion has the magnetic receiver of annular, and described magnetic receiver is provided with several fixing frames extended along coupling shaft axial direction, and permanent magnet compresses and is fixed on the inwall of housing by described fixing frame.In traditional ceiling fan, permanent magnet all utilizes glue to be fixed in inner walls, after a long time use, easily causes permanent magnet to come off because glue lost efficacy.The present invention utilizes magnetic receiver to be fixed permanent magnet, improves reliability.
Further, for ease of assembling, described magnetic receiver has two, and the fixing frame of described two magnetic receivers is relative.When assembling, first what a magnetic receiver being installed, and then permanent magnet being stuck in the fixing frame place of magnetic receiver, finally another magnetic receiver being installed again, all being formed fixing to the two ends up and down of permanent magnet.
Ceiling fan of the present invention fixes flabellum by setting up a dismountable leaf forked cover, instead of is directly fixed on the lower end cap of motor by flabellum, can optimize the production procedure of ceiling fan, enhance productivity and reliability, thus improves the market competitiveness.
