Summary of the invention
The purpose of this utility model provides a kind of electric machine casing that can be fastenedly connected bolt at random, and this electric machine casing can guarantee the machine operation fail safe, can improve the efficiency of assembling of motor again.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electric machine casing, housing is connected and composed by first, second end cap of staving shape, the end face of first, second end cap open-position-side is fitted each other, it is characterized in that: the peripheral region of described first, second end cap open-position-side end face is along circumferentially evenly arranging three connecting holes that connect both.
Described connecting hole comprises first connecting hole that is positioned on first end cap and second connecting hole that is positioned on second end cap, the peripheral region of first, second end cap open-position-side end face radially is outward extended with first, second flange respectively, and first, second connecting hole is arranged on first, second flange.
The peripheral region of the described second end cap open-position-side end face is along the installing hole that circumferentially evenly is provided for fixed electrical machinery, and installing hole and second connecting hole are in upwards dislocation layout of the week of second end cap.
The periphery of the uncovered end face of described second end cap has extended radially outward the 3rd flange (221), and described installing hole is arranged on the 3rd flange.
Described the 3rd flange is evenly arranged four on the periphery of the uncovered end face of second end cap, wherein the centre position of two adjacent the 3rd flanges is provided with second flange, two other the 3rd flange constitutes conjoined structure with other two second flanges respectively, and the central angle that the two installing hole positions that arrange on the flange of described conjoined structure constitute is positioned within the central angle scope of two second connecting hole positions formation.
Offer be used to the wiring hole that is connected ground wire on one conjoined structure of described the 3rd flange and second flange.
Owing to adopt above technical scheme, the week of described first, second end cap is upwards evenly arranged three connecting holes that connect both, that is to say that first, second end cap is to adopt three bolts to carry out both being fastenedly connected, like this in assembling process, operating personnel not only can select connecting hole to carry out the bolt connection at random, need not to follow the fastening technological requirement in diagonal angle, but also be convenient to adjust the position of end cap, to guarantee sealing and the water resistance of motor.Compared with prior art, the utility model had both improved the efficiency of assembling of motor, saved the cost cost of motor again.

Embodiment
A kind of electric machine casing, housing is connected and composed by first and second end caps 10,20 of staving shape, the end face of first and second end caps 10,20 open-position-sides is fitted each other, three connecting holes that connect both are circumferentially evenly arranged on the peripheral region edge of first and second end caps 10,20 open-position-side end faces, and described connecting hole comprises first connecting hole 11 and second connecting hole 21 that is positioned on second end cap 20 that is positioned on first end cap 10.First and second end caps 10,20 adopt three connecting holes to carry out both being fastenedly connected, like this in the assembling process of motor, the connection order indistinction of three connecting holes, operating personnel can select connecting hole to carry out the bolt connection at random, when second bolt is installed, can be finely tuned the position of end cap, so that the accurate applying of first and second end caps 10,20 open-position-side end faces, so both allowed the 3rd bolt install smoothly, the junction that has reduced both again produces the possibility in slit, guarantees sealing and the water resistance of motor.Simultaneously, compared with prior art, first and second end caps 10 of the present utility model, 20 adopt three bolts to connect, and product of every processing like this just can be saved a bolt and a nut, reduce the cost cost of motor, improved efficiency of assembling simultaneously again.
As further preferred version: as shown in Figure 1, 2, the peripheral region of first and second end caps 10,20 open-position-side end faces is outward extended with first and second flanges 111,211 respectively along the radial direction of end face, first and second connecting holes 11,21 are arranged on first and second flanges 111,211, so both save rapidoprint, alleviated the weight of product again.
Further, the peripheral region of described second end cap, 20 open-position-side end faces is along the installing hole 22 that circumferentially evenly is provided for fixed electrical machinery.In order to make installing and fixing of motor possess necessary space, can extend radially outward the 3rd flange 221 at the periphery of second end cap, 20 open-position-side end faces, installing hole 22 is arranged on the 3rd flange 221.As shown in Figure 1, installing hole 22 and second connecting hole 21 are in upwards dislocation layout of the week of second end cap 20, and the Kong Xin of installing hole 22 will be away from the axis of second end cap 20 than the hole core of second connecting hole 21, so both make things convenient for the assembling of motor self, and can realize the installation of other frames such as motor and air-conditioning again.
Further, described the 3rd flange 221 is evenly arranged four on the periphery of second end cap, 20 uncovered end faces, and so both economical with materials can realize the firm installation of motor again.As shown in Figure 1, wherein the centre position of two adjacent the 3rd flanges 221 is provided with second flange 211, two other the 3rd flange 221 constitutes conjoined structure with other two second flanges 211 respectively, the central angle that two installing holes, 22 positions that arrange on the flange of described conjoined structure constitute is positioned within the central angle scope of two second connecting holes, 21 positions formation, adopt the conjoined structure both can economical with materials, alleviate product weight, can improve the bulk strength of connecting portion again.Preferably, can also increase the size of one of them conjoined structure, and offer for the wiring hole 23 that connects ground wire at this conjoined structure, when motor assembles like this, can realize the welding of ground wire or be spirally connected by wiring hole 23.
