Abstract
The present invention relates to a pendulum Central reducer. Its characteristics are: center hole in which input axle and output axle fixed is installed in the headend and tail end of box, and less tooth gear is installed between output axle and input axle. The gear makes two eccentric axle fixed in two side of output and input axle. The tail end of eccentric axle have a 180 degree angle of the eccentric Journal, the importated ring plate translating around input axes is installed in the end of eccentric axle and the two front-end of eccentric axle through the eccentric cover and bearing, on the output ring plate annular gear is made, and cylindrical gear joggled two annular gear at the same time in the end of output axle, This will be maed the four-bar linkage and meshing gears to a integration achieve the meshing tooth difference less to reduce the volume and weight, and increased mutual engagement of the teeth, thereby greatly increasing the intensity of contact, reducing the occurrence of fatigue failure phenomenon, thus the transmission speed ratio (one ninety nine), the transmission torque has been increased by 5 -8 times .Also the invention also has small size, light weight, smooth rotation.
Description
Technical field
The invention belongs to a kind of speed reducer, particularly relate to a kind of swinging-ring speed reducer.
Background technique
Speed reducer is widely used in mine, metallurgy, cement stirring, presses each field such as sugar, lifting transportation, water power plant and navigation boat at present, especially steel industry needs all that velocity ratio is big, output torque is big, reliable, shock resistance, retarding device that overload capacity is strong.Present general speed reducer, such as hard-tooth surface speed reducer, its structure is: have the casing of output shaft and input shaft, the cylindrical gears of double reduction is installed between output shaft and the input shaft in the casing, the velocity ratio of this speed reducer is smaller and easily produce the fatigue damage phenomenon, can not meet the demands; Cycloid speed reducer can be realized bigger velocity ratio, but output torque does not satisfy requirement.
Summary of the invention
The present invention provides the swinging-ring speed reducer that a kind of transmission speed ratio is big, output torque is big for solving the technical problem that exists in the known technology.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of swinging-ring speed reducer, comprise that front-end and back-end have the casing of center hole, be installed in input shaft and output shaft in the center hole of casing front-end and back-end, and the gearing with small teeth differenc with input shaft is connected with output shaft that is installed in the casing is formed, described gearing with small teeth differenc is that input shaft and output shaft bilateral symmetry are installed two eccentric shafts, the rear end of each eccentric shaft is shaped on two sections eccentric journals that are 180 ° of corners mutually, at input shaft inner and two eccentric shaft front ends by one of eccentric bushing and Bearing Installation around the input ring flat-plate of importing the axle center translation, on the eccentric journal of two eccentric shaft rear ends, two output ring flat-plates around output axle center translation are arranged by Bearing Installation, be equipped with ring gear on the output ring flat-plate, be equipped with in output shaft the inner simultaneously and export the cylindrical gearss that the ring flat-plate ring gears mesh with two.
Advantage and good effect that the present invention has are: owing to be shaped on two sections eccentric shafts that are the eccentric journal of 180 ° of corners mutually at input shaft and two rear ends of output shaft bilateral symmetry installation, at input shaft inner and two eccentric shaft front ends by one of eccentric bushing and Bearing Installation around input axle center translation and drive the input ring flat-plate of two eccentric shafts rotations, two output ring flat-plates around output axle center translation are installed on the eccentric journal of two eccentric shaft rear ends, be shaped on the ring gear that drives output shaft gear on the output ring flat-plate, like this quadratic crank mechanism and inside engaged gear are combined together, the cylindrical gears outer gearing changed in few tooth difference mesh, volume and weight is reduced, and the intermeshing number of teeth increases, improved contact strength greatly, reduced the generation of fatigue ruption phenomenon, thereby transmission speed ratio big (1: 99), the moment of torsion of transmission has also improved 5～8 times: also to have a volume little in the present invention in addition, in light weight, the advantage of stability of rotation.

Embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the front-end and back-end of casing 1 are shaped on center hole, input shaft 4 and output shaft 13 are installed in the center hole of casing front-end and back-end, the gearing with small teeth differenc that is connected with output shaft with input shaft is installed in casing, this transmission device is in the bilateral symmetry of input shaft and output shaft two eccentric shafts 2 and 6 to be installed, and the rear end of each eccentric shaft is shaped on two sections eccentric journal 2-1,2-2 and 6-1,6-2 of being 180 ° of corners mutually respectively.By eccentric bushing 5-1,8-1,17-1 and bearing 5,8,17 an input ring flat-plate 3 around input axle center translation is installed in input shaft the inner and two eccentric shaft front ends, the input ring flat-plate can drive two eccentric shafts and rotate under the bearing drive of input shaft off-centre.On the eccentric journal of two eccentric shaft rear ends, two output ring flat-plates 7,11 around output axle center translation are installed by bearing 9,10,15,16, each is exported and is shaped on ring gear on the ring flat-plate, by key 12 while and two cylindrical gearss 14 of exporting the engagement of ring flat-plate ring gears is installed in output shaft the inner.Like this quadratic crank mechanism and inside engaged gear are combined together, realize engagement in few tooth difference, volume and weight is reduced, and the intermeshing number of teeth increases, improved contact strength greatly, reduced the generation of fatigue ruption phenomenon, thereby transmission speed ratio big (1: 99), the moment of torsion of transmission has also improved 5～8 times; The present invention has also that volume is little, in light weight, the advantage of stability of rotation in addition.
