The utility model content
The utility model provides a kind of footing flange the helical cut gear speed motor is installed, and it mainly is to solve the existing in prior technology reducing motor all gears all are installed in box house, makes assembling comparatively complicated, and maintenance is the technical problem of inconvenience etc. comparatively also.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of footing flange of the utility model is installed the helical cut gear speed motor, comprises casing, and casing one end is fixed with the footing ring flange; Cross-under has output shaft on the described footing ring flange; Output shaft is fixed with first helical gear, and first helical gear is engaged with gear shaft, and gear shaft is fixed with second helical gear; Second helical gear connects motor gear, and motor gear is fixed on the motor through motor shaft.First helical gear is installed on the ring flange through output shaft, makes that installation is comparatively simple, can directly dismantle ring flange and can keep in repair or change parts such as first helical gear.Behind the electric motor starting, outputting power is to motor gear, and motor gear is given gear shaft through second helical gear with transmission of power, and gear shaft outputs power through first helical gear, output shaft again.
As preferably, the middle part of described casing is provided with dividing plate, and the inner of output shaft and the middle part of gear shaft all are connected on the dividing plate.Dividing plate can be processed one with casing, and output shaft, gear shaft are more firm above being erected at like this.
As preferably, between described output shaft middle part and the casing, all be provided with bearing between output shaft the inner and the dividing plate.Bearing can guarantee that output shaft is more smooth and easy rotatably, prevents that it from blocking in use.
As preferably, between described gear shaft two ends and the casing, all be provided with bearing between gear shaft middle part and the dividing plate.Bearing can guarantee that gear shaft is more smooth and easy rotatably, prevents that it from blocking in use.
As preferably, be provided with oil sealing between described footing ring flange and the output shaft, can prevent that dust from entering into reducing motor inside.
Therefore, the utility model is installed to power shaft, helical gear in the casing through the footing ring flange, assembles comparatively simply, and it is also comparatively convenient, simple and reasonable for structure to repair.
