Abstract

The utility model discloses a motor shell, which relates to the field of motors and adopts the technical scheme that the motor shell comprises a main body shell, wherein a front end cover and a rear end cover are respectively arranged at two ends of the main body shell, two supporting legs are fixedly connected to the main body shell, an upper radiating fin and a lower radiating fin are arranged on the peripheral wall of the main body shell, a cavity is formed on the rear end cover and the peripheral wall of the main body shell, and the lower radiating fin comprises a main section positioned between the two supporting legs and an extension section positioned in the cavity. The heat dissipation effect of this position is emphasized through increasing the density of lower radiating fin in this position, increases the length of whole radiating fin through setting up the extension to the distance between two adjacent sections extension is bigger, thereby makes on the main section come not the heat that gives off can conduct the extension and give off, has guaranteed the holistic radiating effect of motor housing.

Description

Motor shell Technical Field The utility model relates to the field of motors, in particular to a motor shell. Background An electric motor is a device that converts electrical energy into mechanical energy and generates a force in an electromagnetic field by an electric current to drive rotation or other forms of movement. The motor casing comprises a main body casing, a front end cover, a rear end cover and supporting feet, wherein the supporting feet are fixedly connected to the main body casing, the number of the supporting feet on the main body casing is generally two, the two supporting feet are connected with other platforms through bolts, the front end cover and the rear end cover are respectively positioned at two ends of the motor casing for guaranteeing the overall stability of the motor, a plurality of radiating fins are fixedly connected to the peripheral wall of the main body casing for guaranteeing the overall radiating effect of the motor, and the radiating fins can improve the overall radiating speed of the motor. But the radiating fins are generally distributed on the peripheral wall of the motor shell in an annular uniform array, and the radiating effect of the radiating fins above the supporting legs is relatively good, because the radiating fins are provided with a larger space for radiating heat, but the space between the two supporting legs is relatively narrow, and the supporting legs also influence the heat radiation below the motor shell, so that the motor is positioned between the two supporting legs, and the radiating effect of the motor is relatively poor. New solutions are therefore required to address this problem. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a motor shell. The motor shell comprises a main body shell, wherein a front end cover and a rear end cover are respectively arranged at two ends of the main body shell, two supporting feet are fixedly connected to the main body shell, an upper radiating fin and a lower radiating fin are arranged on the peripheral wall of the main body shell, the upper radiating fin is positioned between the front end cover and the rear end cover, a cavity is formed on the peripheral wall of the rear end cover and the main body shell, the lower radiating fin comprises a main section positioned between the two supporting feet and an extension section positioned in the cavity, the distance between two adjacent main sections is smaller than the distance between two adjacent upper radiating fins, the distance between two adjacent extension sections is larger than the distance between two adjacent main sections, and a radiating hole communicated with the cavity is formed on the peripheral wall of the rear end cover. The utility model is further arranged that a through hole is further formed on one side of the rear end cover, which is back to the front end cover. The rear end cover further comprises a cast iron part and a copper part, wherein the copper part is arranged above the extension section, and all the radiating holes are arranged on the copper part. The utility model is further characterized in that the copper part and the cast iron part are detachable, and the cast iron part is fixedly connected to the main body shell through bolts. The utility model is further characterized in that the copper part is provided with a mounting hole, the cast iron part is provided with a threaded hole, and the copper part and the cast iron part are connected together through a screw positioned in the mounting hole. The utility model is further arranged that an inclined section positioned outside the cavity is also arranged between the main section and the extension section. In summary, the utility model has the following beneficial effects: The heat dissipation effect of this position is emphasized through increasing the density of lower radiating fin in this position, increase the length of whole radiating fin through setting up the extension section, and the distance between two adjacent sections extension sections is bigger, thereby make on the main section come not the heat that gives off can conduct the extension section and give off, the extension section is arranged in the cavity between rear end cover and the main part casing, the distribution density of louvre seting up on the rear end cover is big, make the outside air can be direct get into in the cavity through the louvre on the rear end cover, thereby scatter and disappear the heat on the extension section, can improve the holistic heat dissipation area of lower radiating fin through setting up the extension section, thereby guaranteed the heat dissipation of this part.
