Problems solved by technology

However, this conventional structure can only overcome the radial unbalanced moment, and can only achieve the effect of static balance, but cannot overcome the unbalanced moment caused by eccentricity in the axial direction, so as to achieve the effect of dynamic balance.
Undoubtedly, this kind of structure can only achieve static balance but cannot achieve dynamic balance. The torque generated by the eccentricity of the high-speed rotating input shaft cannot be completely overcome.
This causes severe vibration of the machinery, making it impossible to work
Especially when the shaft speed of the input shaft exceeds 1500r / m, the structure cannot work normally

Embodiment approach

[0012] Referring to Fig. 1, Fig. 2 and Fig. 3, the balance member of the planetary transmission drive mechanism in the mechanical transmission system includes a cylindrical shaft with two 180° arranged key grooves (1 ), four pieces of round through holes with keyways, the same shape and size including eccentricity, eccentric piece (2), and two pieces of flat key (3), installed on the cylindrical shaft in the following order: outside the two eccentric pieces The center line of the circle is installed on the same side of the center line of the cylindrical shaft in the same direction, and the other two eccentric parts are respectively attached to the left and right end faces of the two installed eccentric parts at 180° opposite directions, and the center line of the outer circle is installed on the cylindrical shaft The opposite side of the centerline.

[0013] With reference to Fig. 2, the balance member of the planetary transmission driving mechanism in the mechanical transmiss...

Abstract

The invention comprises an input shaft structure, which has a cylindrical shaft member with two 180 deg arranged key slots and four eccentric members. The eccentric members are mounted on the cylindrical shaft via the connecting keys on them in the following order: the eccentric centre line; the eccentric centre lines of the other two eccentric members are separately close to left and right end faces of the mounted two eccentric members and are mounted in a 180 deg reverse direction on the back side of the cylindrical shaft centre line.

Description

technical field [0001] The invention relates to a balance member of a planetary drive mechanism in a mechanical transmission system, specifically a dynamic balance drive mechanism of a planetary drive with a small tooth difference, that is to say a dynamic balance drive mechanism of a planetary drive with a small tooth difference The structure of the eccentric input shaft. Background technique [0002] In the prior art, people use a conventional single eccentric plus a balanced eccentric input shaft structure or two double eccentric input shaft structures in order to achieve high-speed rotating input shafts. The unbalanced torque generated by eccentricity in the radial direction causes mechanical state of vibration. However, this conventional structure can only overcome the radial unbalanced moment and achieve the effect of static balance, but cannot overcome the unbalanced moment generated in the axial direction due to eccentricity to achieve the effect of dynamic balance....
