Harmonic reducer with lubricating function

Abstract

The invention relates to a harmonic reducer with a lubricating function. The harmonic reducer with the lubricating function comprises a rigid wheel. A flexible wheel is connected into the rigid wheel in a transmission mode. A harmonic generator is connected into the flexible wheel in a transmission mode. The harmonic generator is fixedly connected with a power output shaft of a servo motor. The rigid wheel comprises a motor installation base. An elastic connecting device is arranged between one side of the motor installation base and the servo motor and comprises an annular connecting part fixedly connected with the servo motor. An elastic connecting part is arranged between the annular connecting part and the motor installation base. The annular connecting part is coaxial with the elastic connecting part, the inner diameter of the annular connecting part is the same as the inner diameter of the elastic connecting part, and the outer diameter of the elastic connecting part is smaller than the outer diameter of the annular connecting part. Oil storage grooves are formed in the two side edges of the surface of the inner side of the rigid wheel, and the section of each oil storage groove is in the shape of a circle with notches. The effect that a rotary shaft of the motor is kept being coaxial with the harmonic generator is guaranteed through the elastic connecting device, and the contact surfaces of the flexible wheel and the rigid wheel are lubricated through the oil storage grooves, so that the normal engagement and the linkage effect of the flexible wheel and the rigid wheel are guaranteed, and the service life of the harmonic reducer is prolonged.

Description

technical field [0001] The invention relates to a harmonic reducer with lubricating function. Background technique [0002] Harmonic gear transmission reducer is mainly composed of three basic components: harmonic generator, flexible gear and rigid gear. A gear transmission in which gears mesh to transmit motion and power. Harmonic gear transmission reducer is a new type of reducer developed by using the principle of planetary gear transmission. When the harmonic generator is installed in the flexspline, the section of the flexspline is forced to change from the original circle to an ellipse, and its long axis The teeth near both ends are fully meshed with the teeth of the rigid wheel, while the teeth near the ends of the short shaft are completely disengaged from the rigid wheel. The teeth in other segments on the perimeter are in the transitional state of meshing and disengagement. When the harmonic generator rotates continuously, the deformation of the flexible spline c...

Problems solved by technology

The current harmonic reducer has been installed. To ensure the coaxiality of the servo motor and the harmonic generator during assembly, it is often necessary to frequently adjust the position of the servo motor. At the same time, it is very difficult to detect the tightness after assembly. The lubrication effect between the rigid wheel and the flexible wheel of the wave reducer is not good, and it is easy to cause the flexible wheel to wear during the transmission process
