Abstract
The utility model discloses a double-stage variable-speed reducer, which at least comprises input-stage and output-stage sun gears, input-stage and output-stage planet gears and input-stage and output-stage planet carriers. The input-stage sun gear is meshed with the input-stage planet gear, the input-stage planet gear is fixed on the input-stage planet carrier, the output-stage sun gear is meshed with the output-stage planet gear, the output-stage planet gear is fixed on the output-stage planet carrier, the output-stage sun gear is engaged with the input-stage sun gear via splines, semi-teeth or full-teeth, and the output-stage sun gear is engaged with the input-stage planet carrier via splines, semi-teeth or full-teeth. The double-stage variable-speed reducer is further provided with a connecting rod, the output-stage sun gear is integrally connected with the connecting rod through a fixing part, and the connecting rod drives the output-stage sun gear to be separated from or connected to the input-stage planet carrier under action of external force. The double-stage variable-speed reducer can automatically adjust speed ratio, obtains two different speed ratio output and two different output torques, can control single reduction ratio in a range of 3-64:1, and can reduce production cost.
Description
Technical field
The utility model relates to a kind of retarder, relates in particular to a kind of retarder of realizing the twin-stage speed change.
Background technique
For a long time, it is unalterable that the structure of planetary reducer and even profile adopt traditional mode always.The output operating mode that retarder transmits a kind of speed ratio or regulates retarder by the adjusting actuator.Traditional retarder is provided with the multilayer retarder when needing multi-stage speed-reducing, the structure heaviness can not be adjusted speed ratio voluntarily.
Summary of the invention
Be to solve the above-mentioned problems in the prior art, the utility model provides a kind of twin-stage variable moderator, the output stage sun gear can be axially inwards or outside mobile L, input stage sun gear and output stage sun gear flexibly connect by connecting rod.Masterpiece is used for connecting rod outside, and connecting rod drives the output stage sun gear and breaks away from or connect the input stage planet carrier.Implement the conversion of retarder twin-stage speed change, thereby change the specified output torque and the rotating speed of retarder.
The technological scheme that its technical problem that solves the utility model adopts is as follows: this twin-stage variable moderator comprises input stage and output stage sun gear at least, input stage and output stage planet wheel and input stage and output stage planet carrier, input stage sun gear and the engagement of input stage planet wheel, the input stage planet wheel is fixed in the input stage planet carrier, output stage sun gear and the engagement of output stage planet wheel, the output stage planet wheel is fixed in the output stage planet carrier, between output stage sun gear and the input stage sun gear, all pass through spline between output stage sun gear and the input stage planet carrier, half tooth or full-depth tooth cooperate, also be provided with connecting rod, it is in aggregates that output stage sun gear and connecting rod are connected by fixed block, and the output stage sun gear can move axially.
Axially movable distance (L) is the length of output stage the sun gear spline, half tooth or the full-depth tooth that cooperate with the input stage planet carrier.
Described fixed block is a nut.
The internal spline of the planet carrier of described input stage sun gear and input stage, the length of half tooth or full-depth tooth all should be more than or equal to the length of sun gear external splines, half tooth or the full-depth tooth of output stage.
The twin-stage variable moderator that adopts the utility model to provide can be adjusted speed ratio voluntarily, obtain two kinds of different speed ratio output output torques different with two kinds, and unit reduction speed ratio scope can be controlled in 3～64: 1, can reduce production costs.
