Abstract
A motor casing comprises a casing body and a base for supporting the casing body. A front end cover and a rear end cover are arranged on the casing body. The motor casing is characterized in that the casing body and the rear end cover are molded integrally through stretching, a cavity is formed inside the casing body, and an opening end is stretched outwards to form a flange, and the flange is fixedly connected with the front end cover through a connecting piece. By stretching the casing body directly, a casting casing wall is even in thickness, and the surface of the casting casing is smooth. The motor casing has the advantage of being simple in machining, installing and detaching, low in production cost, environment-friendly and not prone to rust. The inner space of the casing body is increased, the motor is relatively balanced during work, noise and vibration are reduced, service life of the motor is prolonged, concentricity of bearing installing is high, and practicality is good.
Description
Technical field
The utility model relates to a kind of electric machine casing, relates in particular to a kind of end cap of electric machine casing.
Background technology
Chinese patent literature CN201910687U disclosed a kind of electric machine casing on 74 27th, 2011, and it comprises end cap and cylindrical shell, it is characterized in that described end cap is connected on described cylindrical shell with welding manner, made end cap be connected with the cylindrical shell split.The electric machine casing that it is said this structure has been avoided the damage of adopting iron and steel to stretch and cause, makes simply simultaneously, and manufacturing speed is fast, provides cost savings; But, the end cap of this structure and cylindrical shell split arrange, cause the radial dimension of electric machine casing must be consistent with end cap, otherwise when interting bearing, the concentricity inaccuracy can appear, motor can not worked, accurate design and higher manufacturing process so just must be arranged, and lid is arranged so that the production cost raising with the cylindrical shell split, consumptive material is more.Therefore, be necessary further improvement.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, production cost is low, concentricity is high, process and load and unload simple electric machine casing, to overcome weak point of the prior art.
A kind of electric machine casing by this purpose design, comprise casing and the base that is used for support machine casing, be provided with front end housing and rear end cap on casing, it is characterized in that casing and rear end cap one drawing and forming, form cavity in inside, and pull outward in openend and stretch out flange, flange is fixedly connected with front end housing by connector.
Described casing is the shell shape, and front end housing and rear end cap go out front end housing flange and rear end cap flange toward the cavity in-draw respectively, and front end housing flange and rear end cap flange stretch into respectively cavity and be formed with bearing chamber.
Be fixed with front bearing retainer and rear bearing cover by connector respectively on described forward and backward end cap flange, be provided with through hole on front bearing retainer and stretching has bulge loop, stretching on rear bearing cover has protuberance.
The corresponding front bearing retainer of described front end housing is provided with recess, and two all are fixed by connector.
Described front bearing retainer is arranged on front end housing, and is placed in outside cavity, the rightabout that is oriented bearing chamber of its bulge loop; Rear bearing cover is arranged on rear end cap, the rightabout that is oriented bearing chamber of its protuberance.
Described connector is screw or rivet joint.
Stretching place of described each parts is arc transition.
The utility model is by directly stretching to casing, make that foundry goods housing wall thickness is even, surfacing is smooth, not only has advantages of processing and loading and unloading are simple, production cost is low, environmental protection, be difficult for getting rusty, and in casing, the space increases, relative equilibrium, minimizing noise and vibration when making machine operation, increased the useful life of motor, and concentricity is high when bearing is installed, practicality is wide.It has simple and reasonable, production cost is low, concentricity is high, process and load and unload the characteristics such as simple.
