Description
Technical field
The present invention relates to speed reducer fields, and in particular to a kind of wobble ring few teeth difference deceleration device.
Background technique
Speed reducer is widely used in mine, metallurgy, cement mixing, squeezes sugar, lifting transport, power station and navigation boat at present
Etc. each field, especially steel industry, require that transmission ratio is big, output torque is big, reliable for operation, shock resistance, overload capacity
Strong retarding device.Current general speed reducer, such as hard-tooth surface speed reducer, structure is: with output shaft and input shaft
Cabinet, the roller gear of double reduction is equipped in cabinet between output shaft and input shaft, the transmission ratio of this speed reducer compares
It is small and be also easy to produce fatigue damage phenomenon, it cannot meet the requirements；Cycloid speed reducer can realize biggish transmission ratio, but output torque is full
Foot does not require.
Summary of the invention
The purpose of the present invention is to provide it is a kind of it is compact-sized, output torque is big, a kind of big wobble ring of ratio coverage lacks tooth
Subtractive speed variator.
To achieve the above objectives, the technical scheme adopted by the invention is as follows:
A kind of wobble ring few teeth difference deceleration device, including shell, left end cap, right end cap, input shaft and output shaft, right end cap and shell
Right side between baffle is installed, be serially connected with two wobble rings on the input shaft, wobble ring includes centre bore, is distributed on the outside of centre bore
Axis hole and cycloid tooth positioned at outer ring, capacity eccentric bearing is installed in the centre bore of the wobble ring, capacity eccentric bearing is serially connected with defeated
Enter axis, there is crankshaft in the street wobble ring axis hole Nei Chuan, pin wheel housing, the external tooth of the internal tooth of the pin wheel housing and two wobble rings are cased on the outside of wobble ring
The left side of interval engaged transmission, wobble ring is equipped with planet carrier, and planet carrier is supported in the bearing hole of shell right side through bearing, needle tooth
The right side of shell is fixedly mounted through screw and planet carrier, and the crankshaft right end is supported on baffle, the left end warp beam of crankshaft through bearing
It holds and is supported on planet carrier, bearing is socketed on crankshaft, bearing is installed in the axis hole of wobble ring；The center of the planet carrier is equipped with interior
Gear ring, the right end of output shaft are connected with sun gear, and the sun gear is engaged with ring gear；The right end of input shaft is supported on through bearing
Right end cap, the left end of input shaft are supported on the inner hole of sun gear through bearing, and the left end of output shaft is supported on left end cap through bearing.
Further, the capacity eccentric bearing phase difference in two wobble ring centre bores is 180 degree.
After taking above technical scheme, the invention has the benefit that passing through two few teeth differences between wobble ring and pin wheel housing
Transmission after pin wheel housing and planet carrier are fixed, then by planet carrier driving sun gear realization output, reaches structure to increase reduction ratio
Compact and big output torque effect.
