Abstract
The utility model relates to motor fan convenient to disassemble and assemble. The motor fan comprises a fan body and fan blades integrated with the fan body; the fan body is connected with a motor rotating shaft through a key connection piece; a screw hole A is arranged at the non-driving end of the central shaft of the fan body, and a screw hole B is arranged at the end part, corresponding to the screw hole A, of the motor rotating shaft; the diameter of the screw hole A is larger than that of the screw hole B; and the motor rotating shaft and the motor fan can be fixed in a manner that a bolt passes through the screw hole A to be matched with the screw hole B. The fan can be disassembled and assembled easily through the bolt, so that time and effect are saved, the efficiency is high, and the maintenance is convenient.
Description
Technical field
The utility model belongs to motor air exhausting device technical field, is specifically related to a kind of conveniently detachable motor ventilating fan.
Background technique
Traditional motor uses fan mostly to be the open type structure, its have fan body and with the flabellum of its one.Fan and machine shaft Placement are as shown in Figure 1, and machine shaft 1 is fixed through being located at the key link 5 of fan body one with fan 2, and is symmetrical set two back-up rings 3 in the fan body end, comes effectively to prevent that fan 2 from coming off from rotating shaft 1.So,, need use special dismounting frock to utilize two removal holes 4 on the fan to dismantle when dismantling, remove cumbersome like this though fan is fixed.
The model utility content
To the problem that existing technology exists, the utility model purpose is to provide a kind of conveniently detachable motor ventilating fan.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of motor ventilating fan of easy disassembly; It has fan body and with the flabellum of fan body one, fan body is connected with machine shaft through the key link, wherein; Anti-drive end at the fan body central shaft is provided with screw A; Be provided with screw B with the corresponding machine shaft of this screw end, the diameter of said screw A is greater than screw B, utilizes bolt to pass behind the screw A to cooperate with screw B to realize the fixing of machine shaft and motor ventilating fan.
Concrete, the set screw A of the anti-drive end of fan body central shaft model can be M10, and the set screw Type B of machine shaft end number can be M8.
In actual production, motor ventilating fan can adopt the integral molded plastic moulding, can simplify manufacturing procedure like this,
The utility model is provided with screw A through the anti-drive end at motor ventilating fan fan body central shaft, realizes and being fixedly connected of machine shaft.The screw B diameter of machine shaft end is less than the set screw A of fan body central shaft anti-drive end; Tentatively fixing through the key link earlier when installing like this; Utilize again with cooperating with screw B after bolt that machine shaft end screw B is complementary passes screw A to be screwed on the machine shaft, make machine shaft and motor ventilating fan fixed.Earlier former construction bolt is back-outed during dismounting, used instead the bolt that matees with fan body central shaft screw A again, fan is slowly ejected.This fan utilizes bolt can easily realize the dismounting of fan, saving of work and time, and efficient is high and easy to maintenance.
Description of drawingsFig. 1 is the schematic representation that is fixedly connected of used machine shaft of existing technology and fan;
Fig. 2 is the structural representation of the said motor ventilating fan of the utility model;
Fig. 3 is the said motor ventilating fan of Fig. 2 and the machine shaft view with bolt.
Embodiment
Below in conjunction with accompanying drawing the utility model is explained further details, but the protection domain of the utility model is not limited thereto.
Shown in Fig. 2 and 3; A kind of motor ventilating fan 2 of easy disassembly, it have fan body and with the flabellum of fan body one, be provided with key link 5 with the fan body one at fan body central shaft hole place; Fan body is connected with machine shaft 1 through key link 5; Wherein, be provided with M10 screw A 7, be provided with M8 screw B 6 with M10 screw A 7 corresponding machine shafts 1 end at the anti-drive end of fan body central shaft.
During installation; Machine shaft 1 is tentatively fixing through key link 5 earlier with motor ventilating fan 2, utilizes to pass screw A 7 backs with the bolt 8 (being the M8 bolt) of M8 screw B 6 couplings and cooperate with screw B 6 to be screwed in and make machine shaft 1 and motor ventilating fan 2 fixed on the machine shaft 1 again.Earlier the M8 bolt of former installation is back-outed during dismounting, used instead the bolt (being the M10 bolt) that matees with fan body central shaft M10 screw A 7 again and be screwed among the screw A 7 and can simultaneously motor ventilating fan 2 be slowly ejected, make motor ventilating fan 2 be able to separate with machine shaft 1.This motor ventilating fan utilizes bolt can easily realize the dismounting of fan, saving of work and time, and efficient is high and easy to maintenance.
Claims (2)
1. the motor ventilating fan of an easy disassembly; It has fan body and with the flabellum of fan body one, fan body is connected with machine shaft through the key link, it is characterized in that; Anti-drive end at the fan body central shaft is provided with screw A; Be provided with screw B with the corresponding machine shaft of this screw end, the diameter of said screw A is greater than screw B, utilizes bolt to pass behind the screw A to cooperate with screw B to realize the fixing of machine shaft and motor ventilating fan.
2. the motor ventilating fan of easy disassembly according to claim 1 is characterized in that the set screw A of the anti-drive end of fan body central shaft model M10, the set screw Type B of machine shaft end M8.
