Abstract
The utility model discloses a gear box cover of a fan motor. Screw holes used to be connected with a gear box seat is arranged in a cover body. The gear box cover of the fan motor is characterized in that the surface of the gear box cover is provided with a T-shaped groove used to install a capacitor. When the gear box cover of the fan motor is used, an inverted-T-shaped groove which can be connected with the T-shaped groove on the surface of the cover body in embedded mode is arranged on the capacitor of a fan, and the capacitor is inserted on the gear box cover through direct utilization of the fit of the T-shaped groove and the inverted-T-shaped groove. According to the gear box cover of the fan motor, the T-shaped groove structure is used to enable the gear box cover to be matched with the capacitor, a cambered surface with salient points is added on the gear box cover, the groove is added on the capacitor, and the capacitor is fixed on the gear box cover through matching of a concave face and a convex face, and therefore fixing screws for the capacitor are omitted, not only is cost saved, but also the procedure of screwing screws through an air screw driver and a screwdriver is omitted, and installation efficiency is high.
Description
Technical field
The utility model relates to fan electromotor, especially a kind of tooth case lid of fan electromotor.
Background technique
The main working principle of tooth case of fan electromotor is a speed reducer, and the major function of tooth case lid then is sealing tooth block, makes inner tooth class component by the separately fixing motion of track, by screw electric capacity is fixed on the tooth case lid in addition, guarantees the electric capacity normal operation.The tooth case lid of at present industry employing is not of uniform size, and shape is different, but function is all the same.On the tooth case of existing fan electromotor, electric capacity is fixed by screws on the tooth case lid, needs so one by one mounting screw, uses pneumatic screwdriver and screw-driver operation inconvenience, and working efficiency is not high; Existing fan rear casing need to be fixed on around the motor by the metallic interconnect symmetry, and cost is higher.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of saving cost to be provided, save the operation that pneumatic screwdriver and screw-driver are played screw, the tooth case lid of the fan electromotor that installation efficiency is high.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of tooth case lid of fan electromotor is provided with screw for the connection teeth block at lid, it is characterized in that, the surface of described tooth case lid is provided with for the T-shaped groove that electric capacity is installed.During use, fan electric capacity arrange can with the inverted T shape groove of the T-shaped groove tabling of top surface, directly utilize T-shaped groove and cooperating of inverted T shape groove that electric capacity is inserted on the tooth case lid.
In order to make the installation of electric capacity on the tooth case lid more firm, be provided with the salient point cambered surface at described T-shaped groove.During use, corresponding therewith, in the inverted T shape groove of need installation electric capacity, a groove is set, cooperate by male and fomale(M﹠F) electric capacity firmly is fixed on the tooth case lid.
For replacing motor head line wire clamp in the prior art, save element, be provided with crotch at tooth case lid top, the opening of crotch exports towards motor head line.Can block the head line by the crotch intrados like this, and need not to arrange motor head line wire clamp, save element, save cost.
End face at above-mentioned tooth case lid is provided with fan rear casing fixing threaded hole, and described fan rear casing fixing threaded hole is positioned on the tooth case lid cambered surface position, and being centered close on the fan rear casing screw hole center line of screw.This fan rear casing fixing threaded hole replaces metallic interconnect of the prior art, by screw fan rear casing symmetry is fixed on around the motor.
Above-mentioned lid is provided with peripheral flange, and also is provided with stiffening rib on the lid, and described stiffening rib is symmetricly set in tooth case lid Central Symmetry position, on connect the top crotch, the T-shaped groove structure of lower company.Intensity for increasing top crotch and T-shaped groove structure.
The beneficial effects of the utility model are, by T-shaped groove structure tooth case lid and electric capacity are cooperatively interacted, and increase by a salient point cambered surface at the tooth case lid, electric capacity increases by a groove, by the male and fomale(M﹠F) cooperation electric capacity is fixed on the tooth case lid, has removed the electric capacity set screw from, both provided cost savings, save again pneumatic screwdriver and screw-driver and beat the operation of screw, installation efficiency is high; Simultaneously, increase by a screw hole at tooth case lid end face, changing metallic interconnect is plastics, greatly reduces the input of cost of material.
