Description

The eccentric cycloid reducer of a kind of dead axle
One, technical field: the present invention relates to a kind of mechanical transmission speed reducer, the eccentric cycloid reducer of especially a kind of dead axle.
Two, background technique:
Though existing common cylinder gear reducer mechanism is simple, low cost of manufacture, speed ratio is very little; Though the plane table thermoconductivity meter speed ratio is very big,, mechanism's complexity, intensity difference, manufacture cost height, wherein, also there are the big problem of noise in involute less tooth difference and three-ring speed reducer; Though worm type of reduction gearing mechanism is simple, speed ratio is also big, and efficient is low, and input and output shaft can only intercross arrangement, and using scope is restricted.
Three, summary of the invention: the objective of the invention is at the deficiencies in the prior art, a kind of simple in structure, speed ratio is big, intensity good, efficient is high retarder is provided.
The eccentric cycloid reducer of a kind of dead axle, comprise driving wheel and follower, driving wheel and follower are installed in parallel on the casing by input shaft and output shaft and bearing respectively, it is characterized in that, described driving wheel has 3 eccentric wheels at least, 3 eccentric wheels are installed on the same input shaft and 120 ° each other of eccentric directions, perhaps eccentric being installed in respectively in the same way on 3 input shafts of radial equipartition; The follower that is installed on the output shaft is eccentric cycloid wheel; When at least 3 eccentric wheels were installed on 3 input shafts, cycloid wheel was at least 1; When at least 3 eccentric wheels were installed on the same input shaft, cycloid wheel was at least 3, the teeth directional of 3 cycloid wheel certain angle that staggers mutually; Described eccentric cycloid wheel when making pure rolling for eccentric wheel and cycloid wheel two pitch circles, is got point and is done the center of circle on the epicycloid track of selected arbitrarily eccentric point, be that radius is made the formed envelope of series circle with eccentric radius of a circle, that is, and and eccentric conjugate line.Described eccentric wheel is provided with sliding sleeve; Described input shaft also can be by a motor by a central shaft and outer cylindrical gear wheel set synchronous drive by the motor direct-drive of respective numbers.This retarder has following structural feature:
1, this reducer structure is similar to the common cylinder gear reducer, has only driving wheel and follower, and ordinary transmission, so mechanism is simple, volume is little, in light weight;
2, driving wheel is an eccentric wheel, is equivalent to single-tooth gear, thereby its speed ratio equals the number of teeth of follower, so speed ratio is big, wide ranges.Any natural number of its value desirable from 1 to 100;
3, driving wheel and follower can make the hard flank of tooth, improve precision, so, operating steadily, noise is low;
4, driving wheel and follower are the engagement of rolling, and power transfer path is short, so, the transmission efficiency height;
5, the flank of tooth is the concave arc contact, and composite curve radius is big, and the number of teeth is few, tooth proportions is big.So, contact, flexural strength height, bearing capacity is strong.
6, can parallel axes or same shaft drive, so, applied widely.
In sum, plurality of advantages such as this retarder has the structure letter, volume is little, in light weight, speed ratio is big, efficient is high, intensity is good, noise is low, motion is steady, easy to manufacture, cost saving can be used as the mechanical reduction or the multiplying gear of every profession and trade.
Four, Figure of description
Figure (1) is embodiment's 1 plan view; Figure (2) is embodiment's side view; Figure (3) is embodiment 1 theory of engagement figure.Figure (4) embodiment 2 plan views.
Five, embodiment:
In order to help understanding the intent of the present invention, below the invention intention is described further, but the invention intention is not subjected to embodiment's restriction by three embodiments.
Embodiment 1:
The transmission mechanism that present embodiment is based on three-ring speed reducer and cycloidal-pin wheel retarder designs, in the three-ring speed reducer structure, double-crank drives internal tooth ring plate and does circumferential translation, in the movement process, each tooth of internal tooth ring plate is also done circumferential translation around an immovable point in fixing scope, when the gear teeth enter the meshing zone, just with the corresponding gear teeth meshing of central gear, drive the central gear rotating certain angle, when the gear teeth leave the meshing zone, just withdraw from engagement, this shows, each tooth of internal tooth ring plate is equal to only tooth driving wheel of a dead axle motion, therefore, can substitute the whole gear teeth of internal tooth ring plate with only gear of equal number; In addition, in the same time, always have only one of them tooth or several gear and central gear engagement driving, other gear teeth then are to make no load movement, therefore, keeping under the prerequisite of continuous engagement driving, can internal tooth ring plate the number of teeth significantly reduce.In the cycloidal-pin wheel reducer structure, cycloid wheel integrates eccentric motion and rotatablely moves, and pinwheel maintains static, and motion morphology is unbalanced, so, can and rotatablely move eccentric motion and bear by pinwheel and cycloid wheel respectively.
According to last analysis, present embodiment adopts at least 3 eccentric wheels to substitute internal tooth ring plate, that is to say with 3 cranks directly to drive and the cycloid wheel of eccentric wheel conjugation, that is, and central gear.Concrete structure as illustrated in fig. 1 and 2,3 eccentric wheels (2) are fixed in respectively on 3 input shafts (1) that rotate synchronously, cycloid wheel (3) is fixedly connected on the output shaft (4), input shaft (1) and output shaft (4) are installed in parallel on the casing (5) by bearing, and 3 input shafts (1) are distributed in and are positioned on the peripheral circumference of cycloid wheel (3).Its theory of engagement as shown in Figure 3, O 1, O 2Be respectively the center of circle of driven wheel; E is an eccentric circle; B is a cycloid; M, n are respectively the pitch circle of driven wheel; P is a node; K is a contact points; G is a common normal line; Q is the throw of eccentric circle.Two pitch circle m, when n does pure rolling, the track of the last a certain immovable point of q is an epicycloid, on this epicycloid, get point and do the center of circle, be that radius is made the series circle with the eccentric circle radius, envelopes of these series circles are eccentric conjugate line.3 eccentric off-centre contact in position not with cycloid wheel in the same way, when rotating a circle synchronously, successively drive tooth of cycloid wheel rotation jointly.
Embodiment 2:
On the fixedly connected input shafts of 3 eccentric wheels (2) (1) of present embodiment, 3 cycloid wheel (3) are fixedly connected on the output shaft (4), the gear teeth of 3 cycloid wheel certain angle that staggers mutually, input shaft (1) and output shaft (4) are installed in parallel on the casing (5) by bearing.Embodiment 2 the theory of engagement is identical with embodiment 1, just changes eccentric radial arrangement into circumferential arrangement.3 eccentric input shafts are housed also can many to be distributed in and to be positioned on the peripheral circumference of cycloid wheel (3).
