Abstract
The utility model relates to a self-clamping motor fan, having a fan body and a fan blade integrated with the fan body. The fan is mainly characterized in that: a key connecting piece and an elastic clamping piece which are integrated with the fan body into a whole are arranged in a central shaft hole of the fan body. The fan has the advantages of labor economization, time economization, low manufacturing cost, high production efficiency, convenient disassembly, assembly and maintenance, etc.
Description
Technical field
The utility model belongs to the electric motor fan technical field, is specially adapted to the self-clamping type electric motor fan of middle and small motor.
Background technology
In technique known, being used for the structure that the external fan of fire-proof motor usually adopts is: in the metal collar of fan axis hole embedded with metal lining, metallic bond piece and the axle head configuration of injected plastics material, because this fan is the assembly of many parts, in order to guarantee the stationarity of high speed rotating, fan needs to carry out one by one the verification balance on static balance equipment, after reaching standard balance numerical value, just can become qualified finished product.The weak point that the fan of this kind structure exists is: fan installs on the motor shaft extension, dismantle and bother, and processing and assembling procedure are numerous and diverse, take a lot of work, time-consuming, the consumption metal material is many, efficient is low, the manufacturing cost height.
The utility model content
The purpose of this utility model provides a kind of no metalwork, and collection key connector, shackle member are one, and manufacture craft is simple, self-clamping type electric motor fan easy for assembly, disassembly and maintenance.
Realize that the technical scheme that the purpose of this utility model is taked is: this fan have fan body and with the flabellum of its one, in the central shaft hole of fan body, be provided with key connector and resilient clamp member with the fan body one.
Described resilient clamp member is arranged symmetrically on the inwall of fan body central shaft hole, and is provided with the clamping inner convex platform at the clamping free end of this part.
Described fan body, flabellum, key connector and resilient clamp member adopt the moulding of engineering plastics integral molded plastic.
Self-clamping type electric motor fan according to such scheme is made adopts the integral molded plastic moulding, has not only simplified manufacturing procedure, and has cancelled static balance verification operation and static balance equipment, also saves a large amount of metal materials simultaneously.Advantage such as compared with prior art, this fan has the saving of labor, saves time, low cost of manufacture, production efficiency height, dismounting are easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, self-clamping type electric motor fan of the present utility model, form by fan body 1 with flabellum 2, key connector 4, the resilient clamp member 3 of its one, wherein fan body 1 is a lid-like, flabellum 2 symmetries are laid on the end face of fan body, and key connector 4 and resilient clamp member 3 all are located on the central shaft hole inwall of fan body 1.For the concentricity and the spin balancing that guarantee the assembling of fan and motor shaft are stablized, resilient clamp member 3 is provided with more than two, and be on the inwall that is arranged symmetrically in the fan body central shaft hole, the clamping free end of this part is provided with the clamping inner convex platform, cooperate by the annular slot of clamping inner convex platform during assembling, can prevent the axial endplay in the fan use with the motor shaft end position.Only need during the assembling of this fan fan directly is sleeved on the motor shaft and get final product, very convenient.In when maintenance dismounting, only need resilient clamp member is levered up gently, make the annular slot disengaging at clamping inner convex platform and motor shaft end position on the resilient clamp member 3, by the effect of extracting tool on the removal hole 5, fan can be unloaded down easily, very simple and efficient.This fan adopts the moulding of engineering plastics integral molded plastic, can reduce many troubles such as many member processing, assembling smoothing weighing apparatus on the one hand, can save a large amount of metal materials on the other hand, avoids the waste of metal material in the prior art, greatly reduces manufacturing cost.
Claims (2)
1, a kind of self-clamping type electric motor fan, it have fan body and with the flabellum of its one, it is characterized in that: in the central shaft hole of fan body, be provided with key connector and resilient clamp member with the fan body one.
2, self-clamping type electric motor fan according to claim 1, it is characterized in that: described resilient clamp member is arranged symmetrically on the inwall of fan body central shaft hole, and is provided with the clamping inner convex platform at the clamping free end of this part.
