Description
Technical field
The utility model relates to speed reducer technical field, particularly relates to a kind of cycloid speed reducer.
Background technique
Cycloidal planetary gear speed reducer is a kind of applying row planetary transmission principle, adopts the novel transmission device of cycloidal pin teeth engagement.The whole transmission device of cycloidal planetary gear speed reducer can be divided into three parts: input part, deceleration part, output.It mainly forms: two eccentric bushings that a dislocation 180 ° is housed on input shaft, eccentric bushing is equipped with the roller bearing that two are called pivoted arm, the center hole of formation H mechanism, two cycloid wheel is the raceway of rotary arm bearing on eccentric bushing, and be meshed with the pin tooth of one group of annular array on pin gear by cycloid wheel, to form the internal messing reducing gear that tooth difference is a tooth, (in order to reduce friction, in the speed reducer that speed ratio is little, with pin gear sleeve on pin tooth).Its working principle is: when input shaft rotates one week with eccentric bushing, due to the feature of tooth curve in cycloid wheel and by the event of pin gear upper pin gear restriction, the motion of cycloid wheel becomes the plane motion that existing revolution has again rotation, when the positive turn-week of input shaft, eccentric bushing also rotates one week, and cycloid wheel turns over a tooth in opposite direction thus slowed down, relend and help W output mechanism, by the low speed spinning motion of cycloid wheel by bearing pin, pass to output shaft, thus obtain lower output speed.
Speed reducer of the prior art when mounted, if install unreasonable, there will be resonance phenomenon, and input shaft and output shaft can produce mechanicalness noise in rotation process simultaneously.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cycloid speed reducer.
The utility model is achieved through the following technical solutions:
A kind of cycloid speed reducer, comprise upper shell, lower shell body, the lower end of described lower shell body is provided with base, stiffening rib is provided with between base and lower shell body, be installed together by bolt between described upper shell and lower shell body, and the side of lower shell body is provided with oil scale, input device is equipped with in the housing of described upper shell and lower shell body composition, speed reducer and output unit, input device includes input shaft, input shaft is provided with eccentric bushing, eccentric bushing is equipped with roller bearing, speed reducer includes the pin gear sleeve with internal tooth and the cycloid wheel with external tooth, cycloid wheel is provided with the raceway suitable with the roller bearing that is equipped with on eccentric bushing, cycloid wheel is provided with the cycloid wheel pin-and-hole of circumference uniform distribution, the pin gear sleeve with internal tooth and the cycloid wheel with external tooth form few teeth difference engagement, the arranged outside of described pin gear sleeve has the first sound-insulating cover, the arranged outside of described cycloid wheel has the second sound-insulating cover.
As optimal technical scheme of the present utility model, in the housing of described upper shell and lower shell body composition, buffer stopper is installed, and described buffer stopper is rubber material makes.
As optimal technical scheme of the present utility model, described output unit comprises a circular support dish, the axis of described circular support dish side is provided with output shaft, the opposite side of circular support dish is evenly distributed in the supporting disk pin-and-hole matched with the cycloid wheel pin-and-hole of circumference uniform distribution in cycloid wheel, passes through pinned connection between cycloid wheel pin-and-hole and supporting disk pin-and-hole.
