Embodiment 1

[0027] Embodiment 1: Horizontal base with integral structure with rear end cover

[0028] Figure 9 It is a schematic diagram of the assembly structure of a horizontal machine base integrated with the rear end cover. The tensile shell 1 combined with the rear end cover is connected with the base 10 formed by cold pressing of ordinary steel plates to form the whole of the horizontal machine base; the front end cover can be fixed with through-hole bolts as required, or can be screwed through one of the through holes and Another threaded fastening; Windshield 12 ( Figure 11 ) is generally larger than the outer diameter of the shell, and 3-6 inner grooves 13 similar to keyway shapes and equivalent to the outer diameter of the shell are evenly distributed along the periphery, and are socketed and screwed to the rear side of the shell 1 (see Figure 10 ).

Embodiment 2

[0029] Embodiment 2: Vertical frame connected by flange

[0030] The base connection of the first embodiment is removed, and the flange of the front cover is enlarged to the required size of the flange diameter to become a vertical base with flange connection.

Embodiment 3

[0031] Embodiment 3: Vertical base with separated rear end cover

[0032] Figure 12 It is a vertical machine base with separate casing and rear end cover. The front end of the shell is a circumscribed square larger than the diameter of the circular flange (the actual process is to stretch the square after blanking), which is equivalent to the original circular flange part slightly recessed, and the front end remains the same after being installed in the front cover. Some planes. Separated rear end cover ( Figure 7 ) diameter is equal to or slightly smaller than that of the housing 1, the positioning ring 7 cooperates with the bottom plane of the housing to locate the radial position of the bearing chamber, and the hole 5 is matched with the prefabricated screw hole corresponding to the bottom plane of the housing.

Abstract

The invention relates to a cutting-free motor casing, which is molded by a direct stretch process of a sheet metal instead of a heavy pollution metal casting technology molding process. The stretch-molded casting and a rear end cover are combined into one piece and form a motor casing assembly together with a front end cover and a specially designed wind cover. The casting can also be stretched to an ordinary bump strip form. A casting body can be formed by replacing stretch-molding with a metal pipe in order to reduce the equipment tonnage. The motor casing assembly consists of stretch-molded mated end covers and the like.

Description

[0001] The invention relates to a metal casting technology forming process that eliminates heavy pollution, and uses metal plates instead, especially iron plates that are directly formed by stretching process, basically avoiding metal cutting. Background technique: [0002] Except for some low-power micro-motors or special-purpose motors such as explosion-proof motors, the basic structure of various motors commonly used in modern production practice is generally that the stator assembly is embedded in the body shell of metal materials; The reserved lead holes are connected to the connecting terminals attached to the shell of the machine body; the rotor assembly is supported on the center of the end covers at both ends of the machine body through bearings, and a cooling fan is installed at one end of the main shaft of the rotor. cover). [0003] According to industry practice, the main body of the body shell is generally called the machine base, the end cover with the fan end i...
