Abstract
The invention belongs to a novel planetary transmission technology for common machines. A planetary gear transmission device is mainly formed by arranging and combining circular arc-shaped internal (or intermediate) and external gear rings, a planet gear tooth rack and a shockwave device. The advantages and disadvantages of staggered teeth transmission are played and eliminated due to the characteristic of equal tooth pitches and pitch circles of two nested and meshed gears, so as to ensure that complete pure rolling force transmission is realized among force transmission elements, break through limitations at the aspects such as the conventional bearing capacity (shock resistance), return difference precision, torque density (rigidity) and number integrity of meshed (fitted) teeth, relatively ideally realize the working condition of full meshing of nesting and meshing with equal tooth pitches unboundedly in various uses and powers in the whole gear industry. Therefore, popularization and application with lower costs are realized in a large range in the aspects such as hard tooth surface and infinitely variable speed.
Description
Technical fieldthe present application belongs to bearing type gear industry, is the intermediate gearing from prime mover to working machine on the chain drive, is the stronger versatility component of key general character, is used for subtracting (increase, become) speed and correspondingly increases moment of torsion.
Background technique the application is that explanation is unintelligible complete, also jejune CN102072284, ZL2008100964495, ZL2009201549468 mending-leakage application, and omission mutually exists together.
Technical problem how to solve in (expiring) nibble the problem that the involutory off-centre of two-wheeled makes zero in the medial axis? problem Deng tooth pitch transmissions such as pitch circles?
A kind of planetary gear transmission comprises following three parts
Shock wave device is by having double crank shaft or the eccentric wheel of involutory two inclined to one side 180 ° of a amount around the medial axis, and rotary arm bearing and shock wave dish and the gear teeth that involve multiple higher pair power transmission (magnetic, the liquid) body that rolls is formed and nibbled complementation mutually, closes the shock wave that makes zero partially.
Planet carrier by
Two ends, the left and right sides
Mutually the dead axle that makes zero of inclined to one side 180 ° of a amount and moving axis support body pivoted arm each form the planet support body more than two, not only rotation but also moving axis pivoted arm frame (rotating shaft) axle journal that revolves round the sun were bearing on the output disc; Dead axle pivoted arm frame (rotating shaft) axle journal that rotation is not revolved round the sun is bearing on the housing, on this arm axle frame by the stake of the single shock wave dish cover dead axle firm tooth gear that tradition makes zero at axis that is transformed.
Close the beat wheel and close inclined to one side engagement by pitch circle and work (wheel, a pin) tooth depth pair with gear teeth, total number of teeth in engagement is that strange (zero) number equates, each eccentric element that has involutory inclined to one side 180 ° of a amount on this central gear at two ends, the left and right sides, three axis of (making zero on the medial axis) axis assemble the wheel partially that is meshed overlappingly by closing partially.Its velocity ratio i=odd number.
The pivoted arm gear teeth three act on A, will have the single single shock wave dish of two extensions now, by positive and negative inclined to one side rigidity (or nibbling mutually) disjunctor that closes on the wheel of a center (tooth), has the two-way complementation in two ends, the left and right sides, producing moment of torsion when offsetting off-centre rotates, can the envelope curver of flank profil close partially for pure rolling special straight line---circle, be designed to tool rotating center stably, oscillating tooth just divides that to have commentariess on classics (line) fast identical, the rotation that angular phasing is different and revolution.The engaging-in of B, tooth top and tooth paddy goes out by closing deflection to change into rising, descend, and rotation half cycle and the tooth pitch that revolved round the sun half has changed the engagement situation has improved force transferring structure, is the power transmission of full engagement pure rolling.The engagement of C, permanent tooth and oscillating tooth all changes into involutory capacity eccentric bearing
The rolling of outer ring cooperates, and gear rotation is turned to the bearing manufacturing.
The application is characterised in that because having the bearing that the positive and negative two shock wave dishes that close inclined to one side giving young employees remedial-courses in general knowledge and vocational skills are dish disjunctors, be the pure power transmission of rolling fully between each force transmission element, the medial axis of central gear outer (tooth) circle and (every layer of mutual eccentric element) the pairing eccentric axis on it, it is the axis that has three complete coincidences with the involutory eccentric axis formation that input shaft medial axis and its are gone up double-crank, be the off-centre of the extreme ripple of closing of linking of arm axle cover rigidity disk center wheel, close the pitch circle tooth pitch of nibbling two-wheeled and the adjacent contact points of oscillating tooth partially and respective change angle and be and change equate pure and roll transmission.Each gear teeth of complete cycle are to become flexible suit in (or interior) toothed ring gear outside.Addendum=tooth paddy is dark=the wheel tooth diameter of offset=20%～24%, or the flank profil arc diameter.Constitute and to have that to close closing of nibbling that two-wheeled strange (or zero) number of teeth equates eccentric with apart from the higher pair engagement with pendulum, also be convertible into a pairing eccentric drive on the central gear.Other all is solid (awl) gear of the double pendulum close with " side set " transmission, with steel ball, awl, pin, pin, the pivoted arm gear teeth or permanent tooth, reach and shock wave device, planet carrier fixing one circle arbitrarily, come to go out by the purposes permutation and combination structure of various purposes, nibble " waiting tooth pitch " replacement " side set distance " and the hard flank of tooth transmission of part with closing partially.
Beneficial effect both rotation do not revolve round the sun close the pendulum firm tooth gear, be to nibble the pivoted arm gear teeth mutually, in " side set " have loose bowels eccentric rotation and the translation situation of mixing having been distinguished, namely eliminated the error of micro-slippage accumulation; Be of value to elimination " side set " Deng tooth pitches such as pitch circles; undesirable elements such as caused frictional force, bearing capacity, efficient, return difference, kinematic accuracy, vibration; can adopt general circular cutlery, the mold tooling of standard series, scale is low-cost produces in batches, accomplishes the penetration and promotion application.The part number is few, and is simple in structure, and rigidity is big, close beat, gear range is big, convenient realizes differential drive.Be applied to the transmission of large and small power, improved again and closed matter (number) amount of nibbling, moment of torsion close (just) degree can extensively have been given play to beneficial effect in the dual-purpose extremely wide chain drive of military and civilian, and saving can (money) source.
