Technical field
The present invention relates to decelerator technical field, be specifically related to a kind of integration for being arranged on back axle and subtract
Speed device.
Background technology
Decelerator mostly is split-type structural, and dimensions is relatively big, installs complexity, for some narrow space
For occasion (such as back axle position), traditional split-type structural, either manufacture, design and installation the most non-
Often trouble.Meanwhile, traditional decelerator is all with power shaft, jackshaft and differential mechanism, and power shaft is by driving
The motor shaft of dynamic motor drives, and structure is the most more complicated.
Summary of the invention
It is desirable to provide the integral type decelerator that a kind of volume is little, easy for installation, narrow space can be met
Occasion install, the especially installation of back axle position, and eliminate power shaft, by the motor shaft driving motor
Use as power shaft.
To this end, the technical solution adopted in the present invention is: a kind of integration deceleration being applicable to back axle installation
Device, including reducer shell, jackshaft and differential mechanism, described jackshaft is provided with idler gear, in
Between differential gear engaged transmission on gear and differential mechanism, extend about described jackshaft, differential mechanism is positioned at
The underface of jackshaft, described reducer shell uses integrally casting shaping, reducing gearbox intracoelomic cavity upper
Portion is provided with the installing space for driving motor shaft to stretch into and for supporting the bearing driving motor shaft, subtracts
The left or right side of speed device housing is provided with driving motor shaft insertion hole, arranges around driving motor shaft insertion hole
There is motor mounting flange, the lower open of reducer shell, back axle peace it is provided with around uncovered position
Dress ring flange, described differential mechanism local is exposed to open wide outside position and forms semi-packing type decelerator.
Preferred as such scheme, described back axle mounting flange is circular discs, reducer shell bottom
The left and right sides be downwardly extending semicircular installation journal stirrup, each installation journal stirrup is equipped with a semicircle
Ring, what the two ends, left and right of described differential mechanism were respectively placed in correspondence installs in the circular hole that journal stirrup and semicircular ring surround,
Journal stirrup is installed with corresponding semicircular ring by screw lock together.Optimize differential mechanism on reducer shell
Installation, it is ensured that install reliable.
Further, described motor mounting flange is rectangular disk, and rectangular disk is provided with four rectangular cloth
The motor installing hole put, motor installing hole is connected by reinforcement with driving motor shaft insertion hole, improves electricity
The intensity of machine mounting flange.
Beneficial effects of the present invention: using integrated casing, volume is little, easy for installation, can meet space
Narrow and small occasion is installed, and especially the installation of back axle position, eliminates power shaft, by the electricity driving motor
Arbor uses as power shaft, directly drives the idler gear on jackshaft to rotate.
