Abstract
The utility model relates to a double-helical-teeth planetary speed reducer, which is characterized in that an input shaft is connected with a front machine body, an inner tooth sleeve and a sun wheel; the inner tooth clamp is connected with the sun wheel which is connected with a planetary wheel; a planetary frame is connected with the planetary wheel, a left inner tooth ring and a right inner tooth ring; and the left inner tooth ring and the right inner tooth ring are connected with a spring pin in a middle machine body. The double-helical-teeth planetary speed reducer has the advantages that the sun wheel, the left inner tooth ring and the right inner tooth ring are respectively designed to be floated, so as to meet the requirement for uniform contact of tooth surfaces in the operation of double helical teeth and enhances the stability of motion; the inner tooth ring is divided into two bodies, the axial force is born by high-strength bolts so as to be convenient for assembly of the double helical teeth (herringbone teeth); and the left inner tooth ring and the right inner tooth ring are connected with the spring pin in the middle machine body, the spring pin not only can transmit torque, but also can have tiny deformation so as to realize self alignment of the inner tooth ring.
Description
Technical field
The utility model relates to the Gear Planet Transmission speed reducer field in the mechanical transmission, relates to a kind of diclinic tooth (herringbone tooth) planetary speed reducer concretely.
Background technique
Speed reducer is a kind of mechanism of power transmission, and it utilizes the velocity transducer of gear, and the winding number of motor is decelerated to desired winding number, and obtains the mechanism of big torque.At present, the planetary speed reducer that mechanical transmission fields is used generally all is spur gear or helical gear, and under high-speed overload, it is not enough that the stationarity of the strength of gear teeth and motion just seems.
Summary of the invention
Defective in view of the prior art existence, the purpose of this utility model provides a kind of with diclinic tooth (herringbone tooth) replacement straight-tooth or monocline tooth, improve the bearing capacity of planetary speed reducer, improve gear-driven overlap coefficient, make transmission more steady, reduce diclinic tooth (herringbone tooth) planetary speed reducer of noise simultaneously.
For achieving the above object, the technical solution that the utility model adopted mainly comprises: input shaft, preceding body, internal tooth casing, sun gear, planet carrier, planet wheel, left ring gear, right ring gear, high-strength bolt, middle body, spring pin.
A kind of diclinic tooth planetary speed reducer is characterized in that: input shaft is connected with preceding body, internal tooth casing, sun gear, internal tooth casing is connected with sun gear, sun gear is connected with planet wheel, planet carrier is connected with planet wheel, left ring gear, right ring gear, and spring pin links to each other between left ring gear, right ring gear and middle body.
The advantage of described a kind of diclinic tooth planetary speed reducer is: sun gear and left ring gear, right ring gear all are designed to float, and have satisfied that flank of tooth contact evenly strengthens the stationarity of motion in diclinic tooth (herringbone tooth) running; Ring gear is divided into two bodies, and its axial force is born by high-strength bolt, and being convenient to diclinic tooth (herringbone tooth) can assemble; Spring pin links to each other between a left side ring gear, right ring gear and middle body, but both transmitting torque of spring pin can have small distortion again, the self-alignment of realization ring gear.
