Abstract

The utility model discloses a kind of air-cooler end-cap assembly, form the stator comprising end cap and coordinate with end cap, end cap comprises end cap body, bearing chamber is outwardly provided with in the middle part of the end face of described end cap body, be provided with centre bore in the middle part of bearing chamber, the sidewall of end cap body be evenly provided with bending edges outstanding to the inside; Described stator comprises the square shaped stator body that middle part is provided with circular hole in hollow, in hollow, the radial direction of circular hole is evenly provided with multiple punching groove, four angles of square shaped stator body are provided with arc transition limit, and the arc transition limit of described stator body is fixed on the bending edges of end cap body.The utility model not only increases the degree of protection of motor, and improves the utilance of material, decreases installing hole everywhere simultaneously and, on the impact of motor-field, reduces the supplementary load loss of motor; Also improve moment of torsion and the efficiency of motor to a certain extent.

Description

A kind of air-cooler end-cap assembly
Technical field
The utility model relates to a kind of air-cooler end-cap assembly, particularly a kind of air-cooler end cap and stator Interference Fitted Assemblies.
Background technology
Electric motor end cap is a kind of accessory installed with motor case, is used for fixing the critical piece of the stators and rotators of motor.The conventional annoying mounting means of end cap is 4 installing holes and the stator surface installing hole on upper four limits of circle fasten, then adopt screw to run through installation.Such mode can make stator exposed outside end cap, and the degree of protection of motor is on the low side, and has four installing holes due to stator, can reduce the utilance of material, also can affect motor-field, increases the additional energy consumption of motor, affects result of use.
Utility model content
The purpose of this utility model is, provides a kind of air-cooler end-cap assembly.The utility model not only increases the degree of protection of motor, and improves the utilance of material, decrease simultaneously installing hole everywhere on motor-field impact, reduce the supplementary load loss of motor; Also improve moment of torsion and the efficiency of motor to a certain extent.
The technical solution of the utility model: a kind of air-cooler end-cap assembly, it is characterized in that: the stator comprising end cap and coordinate with end cap, end cap comprises end cap body, bearing chamber is outwardly provided with in the middle part of the end face of described end cap body, be provided with centre bore in the middle part of bearing chamber, the sidewall of end cap body be evenly provided with bending edges outstanding to the inside; Described stator comprises the square shaped stator body that middle part is provided with circular hole in hollow, in hollow, the radial direction of circular hole is evenly provided with multiple punching groove, four angles of square shaped stator body are provided with arc transition limit, and the arc transition limit of described stator body is fixed on the bending edges of end cap body.
In aforesaid air-cooler end-cap assembly, described bending edges is 13mm to the port distance of end cap body.
In aforesaid air-cooler end-cap assembly, the projecting height of described bending edges is 2mm.
Compared with prior art, mounting means of the present utility model is for beat in end cap by stator, bending edges fixes end cap corner (four arcs transition limit), it is made to keep flat with end cap, stator can be made like this to be wrapped in completely in end cap, be unlikely to surface exposure in atmosphere, improve the degree of protection of motor; And given up original four installing holes due to stator, employing coordinates with end cap assembles, and is directly installed on the bending edges of sidewall, not only increases the utilance of material, decrease simultaneously installing hole everywhere on motor-field impact, reduce the supplementary load loss of motor; Also improve moment of torsion and the efficiency of motor to a certain extent.Enforcement structure of the present utility model is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of stator.
Being labeled as in accompanying drawing: 1-end cap, 2-centre bore, 3-bearing chamber, 4-end cap body, 5-bending edges, 6-stator, 7-square shaped stator body, 8-punching groove, 9-arc transition limit, circular hole in 10-hollow.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.A kind of air-cooler end-cap assembly, form as illustrated in fig. 1 and 2, the stator 6 comprising end cap 1 and coordinate with end cap 1, end cap 1 comprises end cap body 4, bearing chamber 3 is outwardly provided with in the middle part of the end face of described end cap body 4, be provided with centre bore 2 in the middle part of bearing chamber 3, the sidewall of end cap body 4 be evenly provided with bending edges 5 outstanding to the inside; Described stator 6 comprises the square shaped stator body 7 that middle part is provided with circular hole 10 in hollow, in hollow, the radial direction of circular hole 10 is evenly provided with multiple punching groove 8, four angles of square shaped stator body 7 are provided with arc transition limit 9, and the arc transition limit 9 of described stator body 7 is fixed on the bending edges 5 of end cap body 4.
Preferably, the port distance L of described bending edges 5 to end cap body 4 is 13mm.More optimizedly the projecting height of described bending edges 5 is 2mm.
The bending point of described bending edges 5 is positioned at the inner side of bent end.
Mounting means of the present utility model is for beat in end cap by stator, bending edges fixes end cap corner (four arcs transition limit), makes it keep flat with end cap, stator can be made like this to be wrapped in completely in end cap, be unlikely to surface exposure in atmosphere, improve the degree of protection of motor; And given up original four installing holes due to stator, employing coordinates with end cap assembles, and is directly installed on the bending edges of sidewall, not only increases the utilance of material, decrease simultaneously installing hole everywhere on motor-field impact, reduce the supplementary load loss of motor; Also improve moment of torsion and the efficiency of motor to a certain extent.Enforcement structure of the present utility model is simple, easy to use.
