Iron-shell motor has a housing, and housing comprises the end cap being positioned at motor two ends, and the end cap of existing part iron-shell motor is the end cap stretching and formed.Be respectively installed with damping washer outside two end caps, to reduce vibrations when motor runs, guarantee the stable operation of motor.
As shown in Figure 1, bearing chamber 102 is formed in bottom 101 intermediate recess of stretching end cap, the groove 103 that Formation cross-section is roughly tapered on the bottom 101 of bearing chamber 102 periphery, stretching end cap, the equally roughly tapered installation portion in cross section 202 is down extended in the bottom of damping washer 201, relies on installation portion 202 to be nested in outside bearing chamber 102 to realize the installation of damping washer 201.But the mounting means of this kind of damping washer comparatively bothers, and damping washer easily gets loose in running, cause damping effect to decline, motor is shaken in running and along with noise.
Utility model content
Main purpose of the present utility model is to provide a kind of stretching end cover structure, and this structure is simple, damping washer easy for installation, and solid and reliable, and damping effect is desirable, guarantees the stable operation of motor.
Above-mentioned purpose is achieved by the following technical solution:
A kind of stretching end cover structure, the cylindrical portion comprising bottom and axially extend from bottom outside edge, and on the end of cylindrical portion, extend turn-up portion toward outside, through hole is offered in the middle of bottom, the end face of bottom is provided with base plate, base plate close off described through hole, and countershaft extends bearing chamber outside yearning in the soleplate, is arranged with damping washer outside bearing chamber.
Described above is provided with stepped down part at the internal perisporium of through hole, and the outer ledge of base plate is provided with the portion of topping bar, and the portion of topping bar to be bearing on described stepped down part and to make the end face of base plate concordant with the end face of bottom.
The described above waterproof gasket being provided with annular between the portion of topping bar and stepped down part.
Described above to top bar between portion with stepped down part by together with rivet.
Base plate described above and bearing chamber are formed by sheet iron punching stretch.
The utility model compared with prior art tool has the following advantages:
1) in the middle of bottom, through hole is offered, the end face of bottom is provided with base plate, and base plate close off described through hole, and countershaft extends bearing chamber outside yearning in the soleplate, damping washer is arranged with outside bearing chamber, this structure is simple, damping washer easy for installation, and contact area between damping washer and bearing chamber is larger, adhesion is larger, damping washer solid and reliable, damping effect is desirable, guarantees the stable operation of motor, avoids motor to occur to shake the noise supervened.
2) internal perisporium of through hole is provided with stepped down part, the outer ledge of base plate is provided with the portion of topping bar, the portion of topping bar is bearing on described stepped down part, the location and installation of base plate is simple, convenient, and the end face of base plate is concordant with the end face of bottom, facilitate the installation that stretching end cap is follow-up, avoid the end face due to base plate to protrude from the end face of bottom, cause scratch in some cases.
3) between the portion of topping bar and stepped down part, be provided with the waterproof gasket of annular, effectively ensure sealing and the water proofing property of stretching end cap entirety, avoid because impurity or water enter into the damage that motor internal causes motor, reliability effectively improves.
4) top bar by together with rivet between portion with stepped down part, the advantage of lower cost of rivet, and the mounting means of riveted joint is simple, firmly, design object according to the invention.
