Abstract
The utility model discloses a flange connector used for connecting a water cooler flange of an electric motor, wherein the minimum diameter of the pitch circle of connection screw holes formed on the end surface of a cooler flange of the electric motor is d; four or eight screw holes are distributed uniformly; the maximum diameter of connecting bolts is M; the flange connector comprises a connecting pipe and a flange plate; and the flange plate is connected with one end of the connecting pipe. Eight elongated slots are uniformly formed on the end surface of the flange plate from the pitch circle with the diameter of d to the peripheral surface of the flange plate in the radial direction; the inner ends of the elongated slots are in the shape of closed semicircles, and the outer ends of the elongated slots are opened; the semidiameter of each inner end of each semicircle is R, wherein R equals to M/2 plus 1; and the width of each elongated slot is 2R. The flange connector used for connecting the water cooler flange of the electric motor has simple structure and strong universality, is flexible to use and convenient to install; and the flange connector is suitable for the flange for inflow and outflow water in a cooler, wherein the diameter of the pitch circle of the screw holes ranges from 140 to 210mm, four or eight screw holes are uniformed formed on the flange, and the maximum diameter of the connecting bolts is M20mm.
Description
Technical field
The utility model relates to a kind of flange-interface that is used to connect the water cooler flange of motor.
Background technique
At present, cooler is all leaned in big capacity, the cooling of high performance motor ventilation basically.Motor with water cooler needs the water flowing cooling when general assembly is tested.But because motor size is different, the flange size of water cooler water inlet and outlet also has all size, therefore when motor test, need be equipped with the flange-interface of a large amount of all sizes, bring difficulty for field management, the tool management of test site, and bring pressure to frock manufacturing production, also will take production capital.The water cooler of this same hole of flange-interface need upper water-out pipeline, water return pipeline, motor etc. is used.Usually the key dimension of the water cooler flange of motor is: screw pitch circle 140～210mm, four or eight screws are uniform, the maximum M20mm of connecting bolt.In the prior art, corresponding different screw pitch circles, the flange-interface that screwhole diameter needs different size, screw pitch diameter as the water cooler flange is 140mm, 4-Φ 12 screws are uniform, the size of doing the frock flange-interface of butt joint so will accomplish into: screw pitch circle 140mm, 4-Φ 12 screws are uniform.As long as changing, the screw pitch circle of water cooler flange or screwhole diameter do new flange-interface again again.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of flange-interface that is used to connect the water cooler flange of motor is provided, it simple in structure, use flexible, easy for installation, its highly versatile is applicable to that the screw pitch diameter is 140～210mm, four or eight the water cooler flanges that screw is uniform, connecting bolt is M20mm to the maximum.
The technological scheme that realizes above-mentioned purpose is: a kind of flange-interface that is used to connect the water cooler flange of motor, the minimum diameter of the connection screw pitch circle on the end face of the water cooler flange of described motor is d, screw is evenly equipped with four or eight, the maximum diameter of connecting bolt is M, described flange-interface comprises that an adapter and is connected the flange plate of one of adapter, wherein, on the end face of described flange plate radial equipartition ground from a diameter be d pitch circle to the outer circumferential face of flange plate offer eight the inners for the sealing semicircle, the elongated slot of outer end opening, the radius of this semicircle the inner is R, this R=M/2+1, the width of described elongated slot are 2R.
The above-mentioned flange-interface that is used to connect the water cooler flange of motor wherein, is offered a bayonet slot on the tube wall of the other end of described adapter.
The above-mentioned flange-interface that is used to connect the water cooler flange of motor wherein, is offered an annular groove on the ear end face of described flange plate, set an O RunddichtringO in this annular groove.
The technological scheme of the flange-interface of the water cooler flange that is used to connect motor of the present utility model, its highly versatile is applicable to that the screw pitch diameter is 140～210mm, four or eight water cooler flanges that screw is uniform, connecting bolt is M20mm to the maximum.It simple in structure, use flexibly, easy for installation, can bear 0.5MPa hydraulic pressure and can not leak.
