Abstract
The utility model discloses a herringbone gear planet gear speed reducer, which comprises a planet gear speed reducer. Teeth on a primary sun gear, a secondary sun gear, a tertiary sun gear, a primary planet gear, a secondary planet gear and a tertiary planet gear are all herringbone gears; the primary sun gear, the secondary sun gear and the tertiary sun gear are positioned on an output shaft of the planet speed reducer; and the primary planet gear, the secondary planet gear and the tertiary planet gear are positioned on a box body and are respectively matched with the primary sun gear, the secondary sun gear and the tertiary sun gear. Through the improvement, the meshing strength between each two reduction gears is improved greatly; not only is the transmitted torque increased, but also the noise is decreased; simultaneously, the overall structure is also compact; the volume is reduced; and the cost is decreased.
Description
Technical field:
The utility model relates to gear drive, particularly a kind of low double helical tooth planetary speed reducer of compact structure, stable drive, noise that is applicable to that the big speed ratio gear reduction unit uses.
Background technique:
Existing planetary speed reducer, the tooth on its driving gear all are straight-tooth or helical teeth.The shortcoming that this structure exists is, uses that gear is many, volume is big, cost is high, and the noise of Chan Shenging is big at work, and driving torque is little.
Summary of the invention:
The purpose of this utility model provides the double helical tooth planetary speed reducer that a kind of volume is little, cost is low, moment of torsion is big, noise is little.
The technical solution of the utility model is finished as follows, it includes a planetary speed reducer, it is characterized in that: the tooth on the primary planet pinion that matches with them respectively on the one-level sun gear on the planetary speed reducer output shaft, secondary sun gear, three grades of sun gears and the casing, secondary planetary gear, the three-wheel planet wheel is herringbone gear.The utility model greatly improves the engagement dynamics between each reduction gear through above-mentioned improvement, has not only increased the moment of torsion of transmission, and noise is reduced, and also makes compact overall structure simultaneously, reduces volume, reduces cost.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Further describe embodiment in conjunction with the accompanying drawings.The utility model is improvements over the prior art.Its improvement is that existing herringbone tooth gear is applied on the existing planetary speed reducer, primary planet pinion 5, secondary planetary gear 6, third-level planetary gear 7 cooperatively interacting with them respectively on the one-level sun gear 2 on its output shaft 1, secondary sun gear 3, three grades of sun gears 4 and the casing 8 are mounted to herringbone gear.
