Abstract
The present invention relates to a kind of frame of sheet metal housing, particularly a kind of electric rotating machine with ribbing, bending rib is arranged on the housing, this rib adopts the axial clearance pad that bending rib is connected together on the boundary on the shell inner surface.Purpose of the present invention is accelerated manufacturing speed for cutting down the consumption of energy and reducing machining period, and can continuous batch production.The objective of the invention is the sweep of bending rib to be connected together and realize by axial clearance pad on the boundary of rib on the shell inner surface.
Description
The present invention relates to a kind of frame of sheet metal housing, particularly a kind of electric rotating machine with ribbing, its periphery has some cooling fins, is formed through the pressurization bending by said sheet metal.
Common this cooling fin wall links together with mechanical means or with welding method more commonly used, purpose of connecting is to increase mechanical strength, rigidity and heat conductivility, but adopt the arc welding meeting of continuous weld to consume considerable energy, its power consumption equals even surpasses the required energy consumption of cast casing.Because this shortcoming, its practicality is just lost in the making of sheet metal casing.Other shortcoming also has the difficulty on the manufacturing process, the weld easy deformation of sheet metal, and this distortion becomes " V " font bifurcated from weld.In order to be very difficult for this to happen, the weld shell just must have a kind of very complicated structure.Must adopt complicated clamping apparatus that it is fixed, only these problems just make the expensive waste in man-hour of manufacturing cost for this reason.Also there is sizable internal stress in the shell that welding is good.In order to reduce this stress, to adopt two-way welding sometimes.Adopt this method, the stress of generation has been by low having disappeared mutually, but but the waste of energy consumption produced.Because the gap between rib and the rib is very little, need to change continually the very fast welding rod that has melted again and can only the wall of rib be interlinked together in the bottom of rib, the wall of rib is carried out spot welding or fillet welding is very difficult.Want that difficulty that mechanical link mode with fourth shape rib solves electric welding also is suitable trouble.The essential wall that changes rib stamps out some projections and corresponding to the hole of projection on wall.The result has weakened the elasticity and the rigidity thereof of whole casing.Can make vibration and noise increase also can make the heat conductivility variation of the yoke of stator laminated core again to the sweep of shell.
The object of the invention is intended to overcome partially or entirely above-mentioned shortcoming.
The present invention adopts vertical intermittent weld point that the knee of bending part is connected together on the boundary of the rib on the inner surface of housing.
Compare with the housing or the cast housing that adopt vertical continuous welding to make, the energy consumption of making housing of the present invention has reduced widely.Therefore, make sheet metal housing of the present invention its practical value is arranged again.Weld on the shell inner surface also and can improve mechanical strength and rigidity, each welding portion preferably is arranged on the plane vertical with the longitudinal axis of rib.Further reduce man-hour, boost productivity, also can weld abreast on the housing both sides.Make quantity-produced bigger in batches.Owing to reduced the stress of housing, needn't adopt complicated clamping apparatus.In addition, the heat conduction between shell and the stator laminated core is also very good.
Accompanying drawing has shown most preferred embodiment of sheet metal housing with ribbing of the present invention.Figure 1 shows that the warp-wise partial view of a rib on the electric rotating machine shell, Figure 2 shows that the partial graph of a kind of modified model shell with ribbing of electric rotating machine.Shown in Fig. 1 radial component view, the rib (2) of shell (6) is formed through the pressure bending by sheet metal (1), and two inwalls (3) of this rib are contacted with each other.Adopt vertical intermittent weld (5) that the wall in last two knees of rib (2) is connected together again, welding does not exceed the inner surface of shell (6) diametrically.
Fig. 2 is the part of modified model sheet metal casing (6) shown in the internal view of housing (6).Vertical intermittent weld (5) that the bending edge of sheet metal (1) is opened by 4 sections longitudinal subdivisions connects together, and weld seam (5) is at the inner face of shell (6), and each part tangent plane of following longitudinal seam (5) of each rib aligns mutually.
Clearly, the length between the various piece of the vertical intermittent weld (5) below shell (6) inner face rib (2) and number can be with shown in Figure 2 different.At first, its length and number depend on the size of shell (6), the design of shell (6) and desired rigidity.Vertically every segment length of intermittent weld (5) is preferably between 5 millimeters to 10 millimeters between 1 millimeter to 50 millimeters.Spacing distance between the weld seam (5) of two vicinities is preferably between 50 millimeters to 70 millimeters between 1 millimeter to 200 millimeters.
The present invention's sheet metal housing with ribbing can also be used in the place except that electric rotating machine.Can be applied in and require the rigidity strong component, and its surface needs to adopt the structure of cooling fin to increase its surface area, and improve its heat dispersion, the inner surface of housing with ribbing can be flat or other shape, perhaps on the spot curved cylindrical shape mutually, to spend on the stator laminated core that for example is pressed in electric rotating machine, vertically the each several part of intermittent weld (5) is all tangentially aimed at, perhaps on the plane of one or more longitudinal axis perpendicular to rib, this can improve sheet metal housing rigidity with ribbing.
By vertically the placing in the warp-wise plane on shell (6) edge of intermittent weld (5), can make the marginal portion of shell (6) have required rigidity.
