Abstract
The utility model relates to a large-torque planet cycloidal gear speed reducer, which is characterized in that a shell body with a pin gear is arranged on the end face of a motor; an eccentric bearing is arranged on an output shaft of the motor; a cycloidal gear meshed with the pin gear is arranged on the eccentric bearing; the eccentric bearing is connected with an output shaft of the cycloidal gear through a pin shaft the cycloidal gear; a shell body matched with the output shaft of the cycloidal gear is arranged on the end face of the shell body with the pin gear; a gear ring is arranged at the front end of the shell body of the output shaft of the cycloidal gear; a sun gear is arranged at the end of the output shaft of the cycloidal gear; a planet gear and a planet bracket of the planet gear are arranged between the sun gear and the gear ring, the planet gear is meshed with the sun gear and the gear ring; an output shaft of the planet gear is arranged on the planet bracket; and a shell body which is matched with the output shaft of the planet gear is arranged on the end face of the ring gear. Under the condition of the same machine type, the output torque of the output shaft of the large-torque planet cycloidal gear speed reducer is more than over 2.5 times of that of a twin-stage cycloidal pin gear speed reducer, so as to solve the problem of insufficiency of the output torque of the twin-stage cycloidal pin gear speed reducer.
Description
Technical field
The utility model relates to a kind of big planetary torque cycloidal gear speed reducer.
Background technique
Along with the development of modern industrial technology, all trades and professions are more and more higher to the requirement of speed reducer, especially to large speed ratio, bear the speed reducer type of big torque, and the index request of aspect such as volume is little is strict more.Can reach only 2 grades of transmissions of speed ratio 282(at present) just have only cycloidal planetary gear speed reducer.Present known cycloid pin tooth speed reducer structure is: the housing that has the pin tooth is installed at the motor end face, capacity eccentric bearing is installed on motor output shaft, cycloid wheel with the engagement of pin tooth is installed on capacity eccentric bearing, by the cycloid wheel output shaft that bearing pin is connected with cycloid wheel, the housing of cycloid wheel output shaft is installed at pin wheel housing body end face.Though the speed reducer of this structure has bigger speed ratio, shortcoming is that the output torque is little, can not satisfy the equipment of the big torque of some needs.
Summary of the invention
The utility model provides a kind of compact structure, big planetary torque cycloidal gear speed reducer that bearing capacity is strong for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of big planetary torque cycloidal gear speed reducer, comprise motor, be installed in the housing that has the pin tooth of motor end face, be installed in the capacity eccentric bearing on the motor output shaft, be installed on the capacity eccentric bearing and cycloid wheel pin tooth engagement, the cycloid wheel output shaft that is connected with cycloid wheel by bearing pin, that be installed in pin wheel housing body end face and housing cycloid wheel output shaft coupling, described cycloid wheel output shaft housing front end is equipped with gear ring, cycloid wheel output axle head is shaped on spline, on the spline of cycloid wheel output shaft, spline housing is installed, the sun gear of band coupling spline is installed in the spline housing, planet wheel intermeshing with it and planet carrier thereof are installed between sun gear and gear ring, spline housing is installed on planet carrier, the planet wheel output shaft of band coupling spline is installed in the spline housing, the housing with planet wheel output shaft coupling is installed on the gear ring end face.
Advantage and the good effect that the utlity model has are:
Owing to gear ring is installed at cycloid wheel output shaft housing front end, on the cycloid wheel output shaft sun gear is installed, planet wheel intermeshing with it and planet carrier thereof are installed between sun gear and gear ring, the planet wheel output shaft is installed on planet carrier, the housing of planet wheel output shaft is installed on the gear ring end face, like this under the situation of type of the same race, the output torque of its output shaft can increase more than 2.5 times than twin-stage cycloidal planetary gear speed reducer, has solved the problem of the output torque deficiency of twin-stage cycloidal planetary gear speed reducer.
