The invention will be further described below in conjunction with drawings and Examples.
This composite worm wheel and worm rod pair driving mechanism as shown in the figure, it can form two kinds of structural types under the unified design: one is the driving mechanism that a kind of worm couple and Procedure for Spiroid Gearing are composited; Its two, be the driving mechanism that a kind of worm couple and end face transmission worm gear pair are composited.
Wherein, the driving mechanism that described worm couple and Procedure for Spiroid Gearing are composited (seeing Fig. 1, Fig. 2) is composited by worm couple and Procedure for Spiroid Gearing; This driving mechanism by central shaft 1, first order transmission worm screw 2, first order transmission worm gear 3,3 ' and second level transmission worm screw 4,4 ', second level transmission worm gear 6 constitutes, be located on the central shaft on 1 first order transmission worm screw 2 by with the one-level transmission of one group of first order transmission worm gear 3, the 3 ' formation driving mechanism of its pole face tooth engagement; And the first order transmission worm gear 3,3 in this one-level driving mechanism ' by driving second level transmission spiroid gear 6 with its engagement with the second level transmission worm screw 4,4 of its coaxial rotation ' go; First order transmission worm gear 3,3 ' and second level transmission worm screw 4,4 ' coaxial is done the space planetary motion around first order transmission worm screw 2; Form composite driving mechanism thus with second-stage worm gear worm gear pair form.
Wherein, the driving mechanism (seeing Fig. 3, Fig. 4) that worm couple and end face transmission worm gear pair are composited, this driving mechanism by central shaft 11, first order transmission worm screw 12, first order transmission worm gear 13,13 ' and second level transmission worm screw 14,14 ', second level transmission worm gear 16 constitutes, be located on the central shaft on 11 first order transmission worm screw 12 by with the one-level transmission of one group of first order transmission worm gear 13, the 13 ' formation driving mechanism of its pole face tooth engagement; And the first order transmission worm gear 13,13 in this one-level driving mechanism ' by driving second level transmission spiroid gear 16 with its engagement with the second level transmission worm screw 14,14 of its coaxial rotation ' go; Second level transmission worm screw 14,14 in this scheme ' be the plane worm screw, first order transmission worm gear 13,13 ' and second level transmission worm screw 14,14 ' coaxial is done the space planetary motion around first order transmission worm screw 12; Form composite driving mechanism thus with second-stage worm gear worm gear pair form.
The transmission principle of above-mentioned these two kinds of composite worm wheel and worm rod pair driving mechanisms is as follows:
In a mechanism that is composited by worm couple and Procedure for Spiroid Gearing, worm couple can be thought first order transmission, and Procedure for Spiroid Gearing can be thought second level transmission.Worm couple promptly is the worm gear and the worm drive of common indication, and worm screw can be the plane worm screw, also can be toroid helicoids worm.Usually, make worm screw as motion and power input, the transmission by first order worm couple tentatively underspeeds, and improves moment of torsion.Make the output of first order transmission then, promptly the output of worm gear is as the input of second level transmission.Here, worm gear that can be by making first order transmission is realized with the coaxial setting of taper worm screw of second level transmission.Then, motion and power just can pass through second level transmission, and promptly Procedure for Spiroid Gearing continues to transmit, and speed is further reduced, and moment of torsion is further promoted.
The final result of motion is will be rotated around the worm screw of first order transmission synchronously by the worm gear of first order transmission and the coaxial mechanism that constitutes of spiroid of second level transmission, as the planet wheel in the planet wheel transmission.But different with the transmission of planar row star-wheel is the rotation axis of the in-line gears here and the revolution axis normal that revolves round the sun around worm screw.Spiroid gear in the transmission of the second level will around with first order transmission in the rotation of the same axle center of worm screw.Generally, can be with the support that connects each planetary gear set as final output shaft, also can be with the spiroid gear in the transmission of the second level as finally exporting.
In order to improve bearing capacity, can arrange another set of coaxial worm gear and worm screw in circumference 180 degree directions, also can be according to structure and above coaxial worm gear and the worm screw of uniform in a circumferential direction 2 covers of designing requirement.But it should be noted that in the Procedure for Spiroid Gearing that according to the Hand of spiral of the gear teeth, the spiroid in several covering devices should be selected same rotation direction, and opposite with the spiroid gear rotation direction.
The result of this device transmission is, can realize coaxial input output, and spatial arrangement is convenient, compact structure, and volume is less, gear range big (can up to 10000).And because the Procedure for Spiroid Gearing contact ratio is bigger, so bearing capacity is strong.
In a mechanism that is composited by worm couple and end face transmission worm gear pair, worm couple can be thought first order transmission, and end face transmission worm gear pair can be thought second level transmission.Worm couple promptly is the worm gear and the worm drive of common indication, and worm screw can be the plane worm screw, also can be toroid helicoids worm.The end face transmission worm gear pair here can be thought a kind of special Procedure for Spiroid Gearing, the type of belt drive when promptly reference cone angle trends towards zero.The mechanism that is composited with worm couple and Procedure for Spiroid Gearing compares, and except the spiroid of second level transmission and spiroid gear were substituted by the second level end face transmission worm and worm wheel here, other transmission principle was identical.
In Fig. 1, Fig. 2, the engagement driving of carrying out between worm screw 2 and the worm gear 3 belongs to first order transmission; Engagement driving between spiroid 4 and the spiroid gear 6 belongs to second level transmission.
Central shaft 1 belongs to the key Placement here with worm screw 2, in actual the enforcement, also can be made of one the formula structure to central shaft 1 and worm screw 2.Worm screw 2 here is the plane worm screw.Power and move through central shaft 1 input because the effect that key connects, passes to the worm screw 2 of first order transmission.Because the engagement of worm screw 2 and worm gear 3 makes worm gear 3 become the output of first order transmission, and device speed is reduced, moment of torsion increases.The worm gear 3 of first order transmission is coaxial with the spiroid 4 of second level transmission.They can be linked and packed on the planet wheel shaft 5 by key, also can be and axle 5 disjunctors.Spiroid 4 by with the engagement of spiroid gear 6, will move and power hands on again, speed is further reduced, moment of torsion is further promoted.Planetary carrier 7 can constitute motion and power output by connecting each planet wheel shaft 5.Spiroid gear 6 also can be considered as the output of whole transmission device.Planetary carrier 7 and spiroid gear 6 support on the central shaft 1 by bearing 8 and 9.For the consideration of structural configuration and fit on, the placement positioning block 10 between bearing 8,9 and worm screw 2 end faces of being everlasting.
The first order and second level transmission all belong to the staggered vertical shaft transmission in space, so whole transmission device belongs to the space transmission.In-line gears 3 here and 4 rotation axis and the revolution axis normal that revolves round the sun around worm screw 2.Spiroid gear in the transmission of the second level will around with first order transmission in the rotation of the same axle center of worm screw, though promptly planetary carrier 7 still spiroid gear 6 as the output terminal of transmission, the output axial direction all with import axial direction and overlap.
In order to improve bearing capacity, can arrange another set of coaxial worm gear 3 ' and spiroid 4 ' in 180 degree directions radially.Spiroid 4 is identical with 4 ' rotation direction, and opposite with spiroid gear 6 rotation directions.
The embodiment here just schematically, the structure of real practical application also should comprise end cap and shell and support accordingly and fixture such as location.
In Fig. 3, Fig. 4, the engagement driving of carrying out between worm screw 12 and the worm gear 13 belongs to first order transmission; Engagement driving between worm screw 14 and the worm gear 16 belongs to second level transmission.Second level transmission belongs to end face transmission worm gear pair, is a kind of special Procedure for Spiroid Gearing, the type of belt drive when promptly reference cone angle trends towards zero, and therefore, transmission principle and Fig. 1 are basic identical.
The first order and second level transmission all belong to the staggered vertical shaft transmission in space, so whole transmission device belongs to the space transmission.In-line gears 13 here and 14 rotation axis and the revolution axis normal that revolves round the sun around worm screw 12.Spiroid gear in the transmission of the second level will around with first order transmission in the rotation of the same axle center of worm screw, though promptly planetary carrier 17 still worm gear 16 as the output terminal of transmission, the output axial direction all with import axial direction and overlap.
In order to improve bearing capacity, can arrange another set of coaxial worm gear 13 ' and worm screw 14 ' in 180 degree directions radially.Worm screw 14 is identical with 14 ' rotation direction, and opposite with worm gear 16 rotation directions.
Equally, the embodiment here also just schematically, the structure of real practical application also should comprise end cap and shell and support accordingly and fixture such as location.
Space transmission device involved in the present invention, be to have than the worm and gear transmission of big speed ratio to have carried out suitable compound and stack, simultaneously because the big characteristics of Procedure for Spiroid Gearing contact ratio, the result makes this transmission device have coaxial input output, compact structure, and gear range is big, stable drive, advantages such as bearing capacity is strong, and is little to assembly error receptance, and lubrication property is good.Can be used for fields such as military affairs, communication, space flight and aviation, heavy machinery.
