Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motors, in particular to an end cover of a fan coil motor and a coil motor with the end cover. Background Art
[0002] The end cover of the coil motor used in an AC fan is conventionally made of steel or aluminum alloy. On the inner side of the end cover facing the motor housing, the surface is flat, and there is a bearing hole for installing a bearing at the center position. In view of this, the surface treatment and processing of the motor end cover are required, which makes the processing cost of the product relatively high. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides an end cover of a fan coil motor and a coil motor thereof that can effectively reduce the processing cost.
[0004] An end cover of a fan coil motor, comprising an end cover body. The end cover body is integrally formed by an injection molding process. The inner side surface of the end cover body has a circular convex platform, and the outer side surface of the end cover body has a conical convex platform. A reinforcing rib is connected between the outer peripheral edge of the circular convex platform and the middle part of the end cover body. The center of the circular convex platform has a bearing hole, and a metal bushing is arranged in the bearing hole. The metal bushing is integrally formed with the bearing hole when the end cover body is injection molded.
[0005] To better improve the overall strength of the end cover, eight reinforcing ribs are circumferentially and evenly distributed between the middle part of the end cover body and the outer peripheral edge of the circular convex platform, so as to increase the thickness at the bearing hole on the inner side of the end cover body and improve the support strength.
[0006] To facilitate the docking and cooperation with external components, a ring sleeve is provided on the front end surface of the conical convex platform.
[0007] An axial hole is provided in the ring sleeve, and a tapered hole is provided between the axial hole and the bearing hole to better meet the installation requirements of the motor shaft.
[0008] A fan coil motor, which has the end cover described in any one of the above items.
[0009] The beneficial effect of the utility model is: the utility model is used for a fan coil motor, and is integrally formed by an injection molding method using BMC plastic resin material. By installing a metal bushing in the bearing hole to match with the bearing, the bearing hole can be machined or not machined, and the surface treatment of the end cover appearance can be omitted, effectively reducing the production cost. Using non-metallic materials and insulating materials instead of metal materials can shorten the creepage distance of the end cover. Description of the Drawings
[0010] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Now, the present utility model will be further described in detail in conjunction with the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.
[0015] Such as Figure 1 , Figure 2 As shown, a fan coil motor end cover includes an end cover body 1. The end cover body 1 is integrally formed by an injection molding process. The inner side surface of the end cover body 1 has a circular boss 2, and the outer side surface of the end cover body 1 has a conical boss 3. Among them, the front end surface of the conical boss 3 also has a ring sleeve 7.
[0016] The ring sleeve 7 has a shaft hole 8 inside. The center of the circular boss 2 has a bearing hole 5. A taper hole 9 is provided between the shaft hole 8 and the bearing hole 5. The small end of the taper hole 9 is connected to the shaft hole 8. A metal bushing 6 is provided in the bearing hole 5. The metal bushing 6 is integrally formed with the bearing hole 5 when the end cover body 1 is injection molded.
[0017] Eight reinforcing ribs 4 are connected between the outer periphery of the circular boss 2 and the middle part of the end cover body 1. The eight reinforcing ribs 4 are evenly distributed circumferentially along the outer periphery of the circular boss 2. In this way, relying on the action of the reinforcing ribs 4, the thickness of the bearing hole 5 on the inner side of the end cover body 1 is increased, and the support strength at this place is improved.
[0018] Based on the fan coil motor end cover provided by the above embodiments, a coil motor is provided. The coil motor includes the end cover described in any one of the above embodiments.
[0019] The present utility model is used for a fan coil motor, and is integrally formed by an injection molding method using BMC type plastic resin material. A metal bushing 6 is installed in the bearing hole 5 to match with the bearing. In this way, the bearing hole 5 can be machined or not machined, the surface treatment of the end cover appearance can be omitted, and the production cost can be effectively reduced. Using non-metallic materials and insulating materials instead of metal materials can shorten the creepage distance of the end cover.
[0020] Taking the above-described ideal embodiments of the present utility model as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
