Abstract
The utility model relates to a supporting and sealing device capable of regulating the lengths of rotating arms for planetary motion output shafts, which belongs to the technical field of mechanical driving devices. The utility model is characterized in that a sliding block and a bearing are arranged on a cambered sliding way in a planetary motion device which is composed of an inner gear, and a planet frame and an outer gear, an eccentric disk and a sealing element are arranged on a box body. A regulating device can be utilized to regulate the position of the sliding block in the cambered sliding way to regulate the length of rotating arms of the gears to ensure that the regulation of the eccentric amount at the supporting position of a planetary motion output shaft can be automatically adapted, so that the purpose of supporting and sealing the output shaft is achieved. The utility model has the advantages of simple structure and low cost and automatically adapts the regulation of the eccentric amount at the supporting position of the planetary motion output shaft according to the regulating requirements of the rotating arms from zero to a plurality of millimeters, so that the purpose of supporting and sealing the output shaft is achieved.
Description
One, technical field
The utility model relates to a kind of supporting and seal arrangement of planetary motion output shaft of adjustable pivoted arm length, belongs to the mechanical transmission technical field.
Two, background technique
On numerical control milling bed, in processing and the grinding flute profile cam, aperture when circle or rubbing down plane, often need the very little high speed planetary motion of center cutter offset.Existing all kinds of planet wheel driving mechanism, though planetary pinion is arranged, the concentric dead axle that its input output are central gear or pivoted arm rotates.Therefore at the planetary gear mechanism of designing adjustable pivoted arm length, but it is found that there are some problems in this type of technology, the supporting and the sealing problem that just will solve the adjustable planetary motion output shaft of offset do not solve, so that this gear drive adopts bath lubrication.
Three, model utility content
The utility model be for the planetary gear mechanism that solves existing adjustable pivoted arm length at casing upper support and poorly sealed and propose a kind of new technological scheme.
The utility model is achieved like this: a kind of supporting and seal arrangement of planetary motion output shaft of adjustable pivoted arm length, it is to be provided with two and the intermeshing external gear of internal gear by planet carrier in internal gear, on planet carrier, be provided with cambered way, the center of circle of cambered way overlaps with external gear axle center A, being provided with on cambered way can be along the arc shaped slider of slideway adjusted position, the central shaft B of external gear is bearing on the slide block by bearing, between casing that links to each other with internal gear and external gear output shaft, be provided with bearing, eccentric disc and Sealing, the endoporus of described eccentric disc matches with the axle of external gear, so that realize the rotation of external gear axis, cylindrical then matches with the endoporus of eccentric disc, its cylindrical then matches with the case lid hole, so that realize the revolution of external tooth wheel shaft, can the position of adjusting slider in cambered way by controlling device, so that adjust the pivoted arm length OB of external gear, set eccentric disc and the eccentric disc of output terminal rotates around the center of circle separately simultaneously, regulate with automatic adaptation planetary motion output shaft supporting place offset, thereby realized supporting output shaft; After pivoted arm length OB regulates, this device in the running, do not relatively rotate between the eccentric disc, therefore available " O " shape seal ring seals, use felt ring seal between eccentric disc and the case lid, adopt the lip-type packing sealing between the output shaft of external gear and the eccentric disc, thereby realized the sealing of whole box body.Eccentric disc is to match by bearing and the case lid that is located on the external gear central shaft with eccentric disc, so that realize supporting and regulate pivoted arm length, Sealing is realized the sealing between them.
The utility model has the advantages that: simple in structure, with low cost, can require to adapt to automatically the adjusting of planetary motion output shaft supporting place offset according to the adjusting of pivoted arm between zero to several millimeters, thereby realized supporting and sealing, satisfied on different milling machines the needs on circle in processing and grinding flute profile cam, the aperture or rubbing down plane output shaft.
