DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 7 As shown: A new type of quick-disassembly motor includes a housing 1 and a rotor 2 installed inside the housing 1. The housing 1 is composed of a sleeve 101, an end plate 102 and a rear seat 103. The front side of the housing 1 has a reduction mechanism 4 that cooperates with the rotor 2. The rotor 2 can be decelerated and output outward through the reduction mechanism 4.

[0023] Furthermore, the above-mentioned end plate 102 and rear seat 103 are correspondingly formed with annular end plate convex ribs 112 and rear seat convex ribs 113, and the sleeve 101 with a hollow structure is sleeved on the outer periphery of the end plate convex ribs 112 and rear seat convex ribs 113, so as to be located between the end plate 102 and the rear seat 103. When the rear seat 103 is locked with the end plate 102 by means of a long bolt 123 passing through the sleeve 101, the pressing convex edge 133 formed thereby can press the sleeve 101, so that the sleeve 101 and the end plate 102 are pressed against each other. At this time, the sleeve 101, the end plate 102 and the rear seat 103 are combined together to form the housing 1 for mounting the rotor 2.

[0024] Furthermore, in order to improve the heat dissipation function of the motor, the rear side of the housing 1 also has a heat dissipation cavity; Figure 1-Figure 2 、 Figure 6 As shown, a rear cover 3 cooperates with the positioning buckle 143 of the rear seat 103 through its own U-shaped positioning groove 301. When the two are positioned with each other, the rear cover 3 will be locked to the rear side of the rear seat 103 by screws. At this time, the area between the rear cover 3 and the rear seat 103 is the heat dissipation cavity. The impeller 202 installed at the end of the rotating shaft 201 of the rotor 2 is located in the heat dissipation cavity. The heat of the motor will be dissipated outward through a number of heat dissipation holes formed in the heat dissipation cavity.

[0025] Furthermore, the above-mentioned reduction mechanism 4 is structurally similar to the traditional design, and includes a ring gear 401, a sun gear 402 and planetary gears 403; wherein the ring gear 401 is fixed to the front side of the housing 1, and the sun gear 402 is combined with the rotor 2 shaft 201 passing through the end plate 102, and the three planetary gears 403 are arranged around the periphery of the sun gear 403 and mesh with the sun gear 403 and the ring gear 401. A planetary carrier 404 with an outer shaft 414 combines the three planetary gears 403 into one. When the rotor 2 drives the sun gear 403 to rotate, the planetary gears 403 will drive the outer shaft 414 of the planetary carrier 404 to reduce the output.

[0026] Specifically, the end plate 102 of the above-mentioned shell 1 is surrounded by limiting columns 122 with internal threads. The area enclosed by the limiting columns 122 matches the outline of the ring gear 401. When the ring gear 401 is placed in this area, it will not be able to swing left and right because it is supported by the limiting columns 122. After the sun gear 402, planetary gears 403 and planetary carrier 404 are installed in the ring gear 401 in sequence, a front cover 5 will be installed on the front side of the ring gear 401. A number of bolts 501 are combined with the threaded combination of the limiting columns 122, so that the front cover 5 can press and fix the ring gear 401.

[0027] The installation method of this design is as follows: First, combine the rotor and the housing to form the main part of the motor; second, install the impeller at the end of the rotor shaft, and fix the back cover behind the housing to form a heat dissipation structure; then, install the ring gear, sun gear, planetary gears and planetary carrier in the front of the housing to form a reduction mechanism; finally, install the front cover and lock it to complete the assembly of the motor.

[0028] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
