Description of the Invention: [Technical Field] The present invention relates to a heat-dissipating housing for a motor, and more particularly to an air-cooled motor housing. [Prior Art] ^The existing motor is equipped with a rotor and a mechanical structure such as a main shaft in the outer casing: because it generates high heat when the motor operates, so in order to solve the overheated D distortion, there are multiple dispersions around the outer casing of the motor. The fins expand the eve of the moon ',,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, , ^ "交佳的热交 The above-mentioned existing motor is equipped with a heat-dissipating Korean film to expand the heat-dissipating surface = the active air blowing due to the lack of airflow around the motor, so it is still difficult to quickly motor The heat generated by the operation is brought out, so the efficiency of the heat dissipation of the helmet is easy to cause the horse. ... loss of text, reducing the life of the motor. SUMMARY OF THE INVENTION = There is a heat dissipation effect of the heat dissipation structure of the motor casing, so the capacity == damage. For this reason, the present invention has a space in which the airflow of the motor casing 6 has an air flow, and the air inlet device provided at the rear end of the s housing is forced to intake air to achieve a relatively high heat dissipation effect of the motor. In order to achieve the above objectives, the present invention includes: χ月耠 for an air-cooled motor casing, - a heat-dissipating shell, with a round of internal steam - the same as the '8 Xuan inner cylinder extending in the front and rear directions 'In the outer n-plane of the inner cylinder, a plurality of 201246757 months, one s each of the heat-dissipating fins are protruded outward in the manner of each winding, and the fins extending in the front and rear directions are arranged in the outer tube. a sleeve-outer cylinder, the outer cylinder is a circle S' extending in the front 'rear direction', and a plurality of circumferentially spaced spacers are joined between the inner cylinder and the outer cylinder. The spacers extend in the front and rear directions. The front body surface and the rear end surface of each of the spacers respectively have a front screw hole and a rear screw. The plurality of spacers divide the space between the inner tube and the outer tube into a plurality of heat dissipation. a ventilating passage; a cymbal, a circular cover body and a previous bolt passing through each of the front screw holes of the heat dissipation housing, the front cover closing the front end of the inner cylinder and not closing the front end of each of the heat dissipation vents The middle of the front cover is pierced by a front shaft hole, and the rear side of the front shaft hole has a larger diameter and is embedded therein a front bearing; a rear cover, which is a circular cover body and a later bolt passing through each of the rear screw holes of the heat dissipation case, the rear cover closing the rear end of the inner cylinder and not closing the heat dissipation air passages a rear axle, a rear axle hole is formed in the middle of the rear cover, the front side of the rear axle hole has a larger diameter and a rear bearing is embedded therein, and a plurality of wire holes are pierced around the rear cover; An air inlet device is provided with a wind hood, and the hood cover is coupled to the rear end of the outer tube of the heat dissipation case and is coupled to the air blower around the wind hood. Further, the front cover of the present invention is provided with a front cover plate in front of the heat dissipation case, the front cover plate is a circular plate body having the same diameter as the outer tube, and the front shaft hole is bored in the front In the middle of the seesaw, corresponding to the front end surface of the inner cylinder and the position of each front screw hole, a front connecting ring is extended rearward of the front cover, with the rear end of the front connecting ring abutting The front end surface of the inner cylinder and the front end of each front screw hole correspond to the positions of the respective front screw holes, and a front locking hole is respectively penetrated from the front side of the front cover plate toward the rear, and the front bolt passes through each front lock s 4 201246757 The hole screw is positioned at each of the front screw holes; the rear cover is provided with a seesaw having the same diameter as the inner tube behind the heat dissipation case, the rear cover plate is a circular plate body and is covered by the inner tube a rear end surface, the rear shaft hole is bored in the middle of the rear cover plate, and the wire hole is pierced around the rear cover plate, and corresponds to the rear surface of each of the spacers, on the circumferential surface of the sill plate A rear bump is respectively arranged outwardly, corresponding to the position of each rear screw hole, and a rear locking hole is respectively disposed on the inner side of each rear bump After each of the bolt insertion through the keyhole screwed in the screw holes positioned. Further, the present invention extends obliquely toward the outer half of the lower half of the front surface of the front cover plate, and a front bracket is provided, and a front, σ pupil is bored at the outer end of the front bracket. The lower half of the peripheral surface of the rear sill is opposite to the other side of the front bracket and extends obliquely downward--the rear bracket, and the outer end of the rear bracket is provided with a rear-joining hole. After the leading edge is recessed, the rear recess is sleeved around the rear bracket; a hanging hole is connected between the top of the outer circumferential surface of the inner cylinder and the top of the inner circumferential surface of the outer cylinder, The position of the hanging hole is set in the block, and the front and rear positions of the top surface of the outer peripheral surface of the outer tube are respectively inserted inwardly - the hanging screw holes are respectively screwed to each of the hanging screw holes. Further, the present invention has a front socket protruding from the bottom of the front cover toward the τ.
