Description
Technical field
The present invention relates to a kind of speed reducer for servo motor structure.
Background technique
Retarder is a kind of gear transmission by being enclosed in stiff case, worm drive, the individual components that pinion-endless screw transmission forms, be commonly used for the speed reduction gearing between driving link and working machine, coupling rotating speed and transmitting torque is played between prime mover and working machine or actuator, apply very extensive in modern mechanical, speed reducer is generally used for the transmission device of low rotation speed large torque, motor, internal-combustion engine or other power run up reach the object of deceleration by the gearwheel on the few gears meshing output shaft of the number of teeth on the input shaft of speed reducer, common speed reducer also has and severally reaches desirable slowing effect to same principle gear, the ratio of the number of teeth of large small gear, it is exactly velocity ratio.
Servo-system MANUFACTURER does not produce speed reducer on the market at present.Therefore the speed reducer of actuating motor and configuration is all arrange in pairs or groups that other produce the speed reducer of family as required, this speed reducer is speed reducer supporting to actuating motor specially, the Placement of speed reducer and actuating motor is divided into two kinds on the market: 1) hold mode tightly---and the output shaft of actuating motor stretches into inside speed reducer, and actuating motor and speed reducer pass through Flange joint.Have a deformable anchor ear in speed reducer, the locking nut on operation speed reducer, just can allow anchor ear that the axle of actuating motor is held tightly; 2) keyway Placement---the output shaft of actuating motor and transmission input shaft, by concentric fit axle, adopt keyway edge key positioning transmission.
But existing vibrational power flow has the deficiency of following two kinds of Placements: mode of 1) holding tightly is because of by limited space, and it is all very little that lock screw is joined by institute, therefore extremely easy to slip teeth when locking; 2) the keyway integrating error connected because processing objective reality cause the two ends decentraction of connection.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of actuating motor deceleration integrated mechanism, there is novel combination type structure, overcome the deficiency of existing structure simultaneously, and having good improvement to operation noise, working life is also longer, configuration aspects: assemble simple and convenient, compact structure, reduced space, part simplifies, and cost is lower.
For solving the problem, the present invention adopts following technological scheme:
A kind of actuating motor deceleration integrated mechanism, comprise servo motor output shaft, planetary pinion, planet wheel disc, upper cover of speed changing box and gearbox lower cover, one end of described servo motor output shaft is provided with shaft end gear, described shaft end gear and servo motor output shaft as a whole, operationally center line is made to be same straight line, error very little, described shaft end gear engages with planetary pinion, described planetary centre is provided with through hole, described planetary pinion coordinates with planet wheel fixing pin, described planet wheel fixing pin is fixed on planet wheel disc through through hole, the other end of described planet wheel disc is output shaft, described output shaft is provided with output shaft bearing, described gearbox lower cover is provided with a through hole, described output shaft is through through hole, described through hole is provided with output shaft oil sealing, described planetary pinion outer installment has ring gear, described ring gear engages with planetary pinion, input end bearing is equipped with inside described upper cover of speed changing box, described ring gear is fixed on gearbox lower cover inwall by locating stud, described upper cover of speed changing box is fixedly connected with by king-bolt with gearbox lower cover.
As preferably, described servo motor output shaft is arranged on actuating motor, and the power of actuating motor spreads out of by servo motor output shaft.
