Deceleration member in the past is gear, worm gear etc., and its component volume space all exists for the problem of strengthening flank profil intensity and not being fully used, so the raising of bearing capacity is restricted.
The present invention utilizes " planetary gear train " transmission principle, and causing adjacent each monodentate engagement to pay has constant phase angle difference, and the realization transmission is carried out continuously.
This transmission device has can transmit advantages such as the slow-speed of revolution, heavy duty, large speed ratio, no backlash, compact structure, life-span be long, easy to manufacture, is applicable to industries such as mine, machinery, metallurgy, building.
Description
A kind of one way, heavy-duty decelerator with large single tooth of the present invention belongs to the transmission device of mechanical common engineering.
The existing mechanical speed reducer, its main Force transmission parts is gear, worm gear etc.Because this Force transmission parts is in the course of the work, the flank profil that the contact segment of power transmission is just local, and the overwhelming majority is in not power transmission state, so the volumetric spaces of Force transmission parts can not be fully used for improving flank profil intensity.As a result, the speed reducer of given volume, the raising of its bearing capacity is restricted.
Task of the present invention provides a kind of heavy duty, the transmission slow-speed of revolution, unidirectional speed reducer that makes full use of the Force transmission parts volumetric spaces.
Task of the present invention is achieved in that the transmission principle of utilization " planetary gear train ", and by the selection to profile of tooth, the number of teeth, number of components, causing adjacent each monodentate engagement to pay has constant phase angle difference, and the realization transmission is carried out continuously.
Concrete member of the present invention, structure and transmission process are provided by following embodiment and accompanying drawing thereof.
Accompanying drawing 1 is the structure principle chart of the specific embodiment of the invention 1.
Accompanying drawing 2 is transmission principle figure of the present invention.
Accompanying drawing 3 is transmission working state figures of specific embodiments of the invention 1.
Getting driving lever body (5) number of packages n in the accompanying drawing 1 is 4, and it is 17 that inner ratchet tooth ring (17) ratchet is counted Z.Input shaft (11) is connected mutually with input shaft large single tooth (9), and output shaft (2) is connected mutually with output shaft garden dish (3), and driving lever ring support (7) pine is enclosed within on the casing (6), and is fixed with output shaft garden dish (3) by bolt (10).The two ends of 4 driving lever bodies (5) are enclosed within input shaft garden dish (3) and driving lever ring support (7) each 4 along in the driving lever body rotary shaft hole of garden Zhou Junbu by its driving lever body rotating shaft (4,8) pine.4 movable driving levers (12) insert in 4 corresponding driving lever bodies (5) sliding-groove, and movable driving lever (12) one ends contact with the ratchet of inner ratchet tooth ring (17), and the other end contacts with pressing spring (13).Draw spring seat (15) to draw spring (14) fixing by being installed in 4 of driving lever body (5), 4 rollers (16) that are assembled in 4 driving lever body (5) one sides are remained with input shaft large single tooth (9) contact 4.
See from accompanying drawing 1,2, its transmission process is: input shaft (11) rotation drives input shaft large single tooth (9) rotation that is connected with it, input shaft large single tooth (9) is stirred roller (16) with its loaded work piece section, at this moment, movable driving lever (12) rod end embeds the ratchet face of inner ratchet tooth ring (17), because of inner ratchet tooth ring (17) and casing (6) are connected, the driving lever body (5) that the result only does to swing is by passing to motion on the output shaft garden dish (3) that is connected mutually with output shaft (2) with its driving lever body rotating shaft (4,8) that is connected.Because input shaft large single tooth (9) loaded work piece section has the profile of Archimedes spiral and contact ratio greater than 1 profile length; Driving lever body (5) number of packages n(n is the positive integer greater than 2, and present embodiment 1 is got n=4); Inner ratchet tooth ring (17) ratchet is counted Z=(nm+1), (m is the positive integer greater than 3, present embodiment 1 is got m=4), just make each monodentate engagement that the adjacent ratchet face that is assembled in roller (16) on each driving lever body (5) and movable driving lever (12) and input shaft large single tooth (9) and inner ratchet tooth ring (17) constitutes pair constant phase angle difference be arranged, make the transmission of motion can be evenly successive.Each Force transmission parts has guaranteed no backlash operation all the time to be close to the mode power transmission.
Embodiment 2: n driving lever body (5) arranged, and inner ratchet tooth ring (17) has (nm+1) individual ratchet, and ratchet circular pitch arc length is the one way, heavy-duty decelerator with large single tooth of t, and how the profile of tooth, the number of teeth, the number of components that the following describes it are selected.
Input shaft large single tooth (9): its profile divides loaded work piece section and unloaded carry section.The loaded work piece section has the Archimedes spiral profile, and its profile initial point radius vector, is made by the residing position of roller (16) behind the flat embedding of promptly movable driving lever (12) pole face inner ratchet tooth ring (17) ratchet face according to initial state with graphing method.When the profile Changing Pattern should guarantee that input shaft large single tooth (9) turns over ((360 °)/(n)-(360 °)/((nm+1)) 1/ (n)), movable driving lever (12) rod end was by initial state forward swing (t)/(n) arc length.For making contact ratio greater than 1, the radius vector angle of loaded work piece section desirable { ((360 °)/(n)-(360 °)/(nm+1) 1/ (n))+20 ° }.Remaining part is unloaded carry section, its head, not two ends just the loaded work piece section not, first two ends.Unloaded carry section is the radius vector length of (360 °)/(n) locate from loaded work piece section initial point radius vector angle, and the residing position of roller (16) is determined during from initial state backswing (2t)/(n) arc length by movable driving lever (12) rod end.Three points that the method for using is made are done a garden, then the profile of unloaded carry section.
The number of packages n of driving lever body (5), n are the positive integer greater than 2, and after n was selected, the ratchet tooth number Z of inner ratchet tooth ring (17) must be chosen as: Z=(nm+1), for slowing down, m was the positive integer greater than 3, at this moment can get velocity ratio: i=mn.
Movable driving lever (12) is a rectangular cross section, and rod end is that the plane connects garden arc structure.
Inner ratchet tooth ring (17) is an inner ratchet tooth ring of design routinely.
Accompanying drawing 3 is transmission working state figures of the specific embodiment of the invention 1.Wherein a is an initial state; B is input shaft large single tooth (9) working state when turning over ((360 °)/4-(360 °)/17 1/4) 1/2 angle; C, d, e, f are input shaft large single tooth (9) revolution working state when crossing the the 1, the 2nd, the 3rd, the 4th ((360 °)/4-(360 °)/17 1/4) angle.
The embodiment of the invention 3: driving lever body (5) number of packages n=4, inner ratchet tooth ring (17) ratchet is counted Z=33, and the one way, heavy-duty decelerator with large single tooth of velocity ratio i=32 and JZQ1000-III compare:
One way, heavy-duty decelerator with large single tooth of the present invention has can transmit the advantages such as the slow-speed of revolution, heavy duty, large speed ratio, no backlash, compact conformation, life-span be long, easy to manufacture, is adapted to the industries such as mine, machinery, metallurgy, building.
