Specific embodiment
Below in conjunction with attached drawing, the present invention is further described:
Please refer to Fig. 1 and Fig. 2, a kind of speed reducer based on split type shell, including main shaft 1, planetary gear 13, crankshaft 3, pendulum
Spool holds 15, shell and cycloidal-pin wheel 5；Shell is hollow assembling structure, and main shaft 1 is co-axially located at the geometric center of shell；Three
A crankshaft 3 is parallel to the radians such as main shaft 1 and is arranged on the circle centered on main shaft 1；The upper end of each crankshaft 3 is fixedly installed
Planetary gear 13, the upper end of main shaft 1 are fixedly installed gear, and gear is engaged with all planetary gears 13；Fixation is arranged on each crankshaft 3
There are two cycloid bearing 15, it is arranged that there are two cycloidal-pin wheels 5 on main shaft 1, there are hole, crankshaft in the position that cycloidal-pin wheel 5 is located at crankshaft
It is arranged across hole, and two cycloid bearings 15 on each crankshaft are respectively positioned in the hole of cycloidal-pin wheel 5；It is arranged on case inside wall
There are the internal tooth being meshed with 5 edge of cycloidal-pin wheel, cycloidal-pin wheel and interior tooth engagement；Shell include five annulus, five annulus according to
Secondary coaxial threaded is fixedly connected to form shell.
Two cycloidal-pin wheels 5 on main shaft 1 form cycloidal-pin wheel group, and the upper and lower side of cycloidal-pin wheel group is respectively provided on crankshaft 3
There is spring bearing 4.
Shell is provided with ball bearing 6, the outer ring of ball bearing 6 and shell end inner sidewall far from the opening of planetary gear one end
