Abstract
The utility model discloses a tubular motor helical tooth planetary reduction gearbox which comprises a coupling, an internal tooth sleeve cover, an internal tooth sleeve, an internal tooth sleeve seat, a primary sun gear, a primary support, a primary planetary gear, a secondary support, a secondary planetary gear, a three-level planetary gear and a third-level support, wherein the primary support is provided with a secondary sun gear, and the second support is provided with a third-level sun gear; and the tubular motor helical tooth planetary reduction gearbox is characterized in that the primary sun gear and the primary planetary gear are helical gears, one end of the internal tooth sleeve has helical teeth and the other end has straight teeth. For the tubular motor helical tooth planetary reduction gearbox, as the primary planetary reduction part running at high speed adopts a helical tooth structure with larger coupling coefficient, the running stability is increased, and the noise reduction is facilitated during the running of the motor. The tubular motor helical tooth planetary reduction gearbox has the characteristics of simple structure and no noise.
Description
Technical field
The utility model relates to a kind of speed reducer structure of motor, specifically is meant a kind of tube shaped electric machine helical teeth planetary reduction box that is applicable to tube shaped electric machine.
Background technique
Tube shaped electric machine is elongated tubulose, the multistage planetary reduction box of the general employing of the speed reducer of tube shaped electric machine, and the tube shaped electric machine planetary reduction box of prior art adopts straight-tooth, and the gear engagement coefficient is less, and the noise of motor operation is bigger.
Summary of the invention
The utility model is at the problems referred to above, proposes the little tube shaped electric machine helical teeth planetary reduction box of a kind of running noises.
The purpose of this utility model is achieved in that a kind of tube shaped electric machine helical teeth planetary reduction box of the present utility model, it comprises coupling, internal tooth upper shield, internal tooth casing, internal tooth block set, one-level sun gear, one-level support, primary planet pinion, secondary support, secondary planetary gear, third-level planetary gear, three grades of supports, on the above-mentioned one-level support secondary sun gear is arranged, three grades of sun gears are arranged on the secondary support, it is characterized in that one-level sun gear, primary planet pinion are helical gears, one end of internal tooth casing is a helical teeth, and the other end is a straight-tooth.
Tube shaped electric machine helical teeth planetary reduction box of the present utility model owing to partly adopt the bigger helical teeth structure of contact ratio at the one-level planetary reduction gear that runs up, has increased the stationarity of running, the noise when helping reducing the motor operation.Tube shaped electric machine helical teeth planetary reduction box of the present utility model has simple in structure, quiet characteristics.
