Abstract
The invention discloses a dual-input power dividing differential planetary reducer. Power enters an input end gear pair from double input shafts, is divided by a differential inner gear ring and an input end driven gear and is output from an output flange at a reduced speed by resultant motion of a differential planetary gear pair; smaller size and larger transmission ratio of the planetary reducer can be achieved under the conditions of the same strength, so that the machine has a more compact structure; the machine is made into a suspension type one and directly connected with a mill cylinder by the output flange for the application occasion such as a cement grinding mill and the like, so that a transmission shaft is saved, and only a torque stand on a machine shell is in contact with the ground to balance the rotating torque of a mill, avoid the influence of the vibration and displacement generated during operation of the mill on the gear and a bearing and ensure reliable operation of the machine; and thus the arrangement size is reduced and the investment on the infrastructure such as factory buildings and the like is reduced.

Technical solution of the present invention is: this speed reducer constitutes by input end driving gear, input end driven gear, input shaft, differential ring gear, planet wheel shaft, sun gear, planet wheel, planet carrier and output flange are installed in the housing; Housing is a deciliter face structure; End in housing is installed two input shafts through bearing of input shaft respectively; The input end driving gear is installed on the input shaft; Differential ring gear through divided bearing and output terminal Bearing Installation in housing, in housing between two input shafts through sun gear bearing installation sun gear, the input end driven gear is installed on the sun gear; Input end driving gear and input end driven gear are " one " font and arrange; The input end driving gear simultaneously and input end driven gear and the engagement of differential ring gear input end, the planet carrier Bearing Installation of planet carrier through two ends on differential ring gear, planet wheel through planet wheel shaft and planet axis Bearing Installation in planet carrier; At least three planet wheel circular array are distributed between differential ring gear and the sun gear, connect output flange on the planet carrier; It is secondary that the driving and driven gear of differential ring gear input end and input end is formed input end gear; It is secondary that differential ring gear output terminal and planet wheel and sun gear are formed the output terminal differential planet gear.
Wherein, described each gear pair all adopts the hard flank of tooth of involute and middle hard gear-face profile of tooth.
Wherein, between sun gear and planet carrier, be provided for the anti-wear gasket of axial limiting.
Wherein, torque stand is installed on housing, speed reducer connects with ground through torque stand.
During work; Dual input shaft drives the input end driving gear simultaneously and rotates; The input end driving gear meshes input end driven gear and differential ring gear input end simultaneously, thereby sun gear rotates with the input end driven gear, and the output terminal of differential ring gear and the resultant motion of sun gear drive planet wheel and revolve round the sun along sun gear; Planet wheel drives the planet carrier gearing down, outputs power through output flange.
Can reach following effect according to above solution: 1. speed reducer adopts the double input form to satisfy the requirement of the high-power input of machine; 2. only just reach the velocity ratio output of common multi-stage planetary gear transmission, satisfy in the market usage requirement the speed reducer big speed ratio with the transmission of single-stage differential planet gear; 3. the differential planet gear transmission can make power on ring gear and sun gear, shunt, and machine can obtain littler volume and weight under the equality strength condition, and machine construction is compact more; 4. vibration that underslung torque stand produces in the time of can absorbing mill running and displacement reduce floor space simultaneously to the adverse effect of machine, shorten the infrastructure construction cycle, reduce cost.
