Abstract
The utility model discloses a cycloidal speed reducer, which comprises a casing. An input device, a speed reducing device and an output device are assembled in the casing. The input device comprises an input shaft, an eccentric sleeve is sleeved on the input shaft, and a roller bearing is mounted on the eccentric shaft. The speed reducing device comprises a pin gear sleeve with inner teeth and a cycloidal wheel with outer teeth, a raceway matched with the roller bearing mounted on the eccentric shaft is arranged on the cycloidal wheel, cycloidal wheel pin holes which are distributed uniformly are arranged on the cycloidal wheel, and the pin gear sleeve with inner teeth and the cycloidal wheel with outer teeth mesh with each other with small tooth difference. The output device comprises a circular supporting plate, an output shaft is arranged on the axis of one side of the circular supporting disc, supporting disc pin holes which are matched with the cycloidal wheel pin holes uniformly distributed on the cycloidal wheel circumferentially are uniformly distributed on the other side of the circular supporting disc circumferentially, and the cycloidal wheel pin holes and the supporting disc pin holes are connected via pins. The cycloidal speed reducer has the advantages of evident speed reduction, higher efficiency, compact structure and stability in operation.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of cycloid speed reducer.
Background technique
Cycloid speed reducer includes housing, is equipped with input device, speed reducer and three parts of output unit in the housing, but the common structure of existing cycloid speed reducer is complicated, and volume is big and efficient is lower.
Summary of the invention
At the deficiencies in the prior art, the utility model provides that a kind of reduction speed ratio is big, efficient is high, running is steady, the cycloid speed reducer of compact structure.
For achieving the above object, the utility model provides a kind of cycloid speed reducer, include housing, be equipped with input device in the housing, speed reducer and output unit, input device includes input shaft, be arranged with eccentric bushing on the input shaft, roller bearing is housed on the eccentric bushing, speed reducer includes pin gear sleeve with internal tooth and the cycloid wheel with external tooth, cycloid wheel be provided with eccentric bushing on the suitable raceway of roller bearing that is equipped with, cycloid wheel is provided with the cycloid wheel pin-and-hole of circumference uniform distribution, pin gear sleeve with internal tooth constitutes few tooth difference engagement with the cycloid wheel with external tooth, output unit comprises a circular support dish, the axis of described circular support dish one side is provided with output shaft, the opposite side of circular support dish is evenly distributed in the supporting disk pin-and-hole that matches with the cycloid wheel pin-and-hole of circumference uniform distribution on the cycloid wheel, is connected by bearing pin between cycloid wheel pin-and-hole and the supporting disk pin-and-hole.
The beneficial effects of the utility model are: adopt said structure, because cycloid wheel and pin gear sleeve are formed few tooth difference engagement, when the input shaft band the eccentric bushing rotation during one week, the existing revolution of cycloid wheel has spinning motion again, when input shaft just circles, eccentric bushing also just circles, the angle of a few tooth difference of reverse rotation when the cycloid wheel public affairs circle, thereby obtain slowing down, relend and help the hole-pin output mechanism, the low speed spinning motion of cycloid wheel is passed to output shaft, thereby obtain lower output speed, so compare existing cycloid speed reducer, cycloid speed reducer provided by the utility model, its reduction speed ratio is bigger, efficient is higher, compact structure and running are steadily.
The utility model can further be set to the central axis of described input shaft and output shaft on same straight line.
The utility model also can further be set to be provided with pin sleeve between cycloid wheel pin-and-hole and the bearing pin.
The utility model also can further be set to described housing and be set firmly by bolt by support and flange plate and constitute.
