Abstract
The present invention relates to a screw transmission mode and a screw transmission device. The screw transmission mode comprises: a driving wheel drives a screw shaft ring to rotate, the screw shaft ring drives a driven wheel to rotate, and a roller in the driven wheel rotates along the screw surface of the screw shaft ring, so that the driven wheel rotates by using the screw shaft ring as the axis. The present invention has the characteristics of favorable self-lock performance, great transmission torsion, high transmission efficiency, stable transmission, large interval of the transmission shafts, etc. The present invention can be used in various mechanical equipment appliances requiring the characteristics.
Description
The present invention relates to transmission device, specifically is a kind of helicoidal gear.
The transmission device of prior art mainly contains: forms such as worm and gear transmission, gear transmission, belt transmission, power screw, and in above-mentioned each transmission device, gear-driven efficiency is higher, but self-locking property is poor; Worm and gear transmission self-locking property is good, but transmission efficiency is relatively low; Belt Transmission Efficiency is not high, but it adapts to the bigger occasion of distance between shafts; Power screw are more steady, and velocity ratio is big, existing are used for straight-line occasion mostly, for transmitting than high pulling torque, and require self-locking property good, and distance between shafts is relatively large, and the device that transmission efficiency is higher is the problem that people's idea solves always.
It is good to the purpose of this invention is to provide a kind of self-locking property, can transmit high-power moment of torsion, and the transmission efficiency height, and distance between shafts is relatively large, the stable transmission helicoidal gear.
The present invention is achieved by the following technical solutions:
It is a kind of helicoidal gear, comprise main shaft (2) and be installed in driving wheel (1) on the main shaft (2), driving wheel (1) drives the spiral axle collar (3) and rotates, the spiral axle collar (3) is by follower (5), it is characterized in that the spiral axle collar (3) ring-type in the shape of a spiral, driving wheel (1) is meshed with tooth on the spiral axle collar (3), roller (4) is installed in the follower (5), roller (4) is linear with each side of the spiral axle collar (3) and contacts, the both sides mounting bracket (7) of follower (5), two of the installed inside of support (7) are with upper roller (6), and roller (6) contacts with the bi-side of follower (5).
Have groove in the above-mentioned spiral axle collar (3), be fixed with tooth in the groove, and tooth is meshed with the tooth of driving wheel (1), the shape of cross section of the spiral axle collar (3) can be triangle, quadrilateral, pentagon, Hexagon and polygonal, the roller of installing in follower (5) (4) can be more than 3 or 3, and each roller (4) all contacts with each side of the spiral axle collar (3); Supporting wheel (8) more than 3 or 3 is installed on the frame (9), and supporting wheel (8) contacts with the internal surface of the spiral axle collar (3).
Helicoidal gear of the present invention is simple in structure, installation is easy for installation, and processing ease, and stable drive can be used for multiple place, can transmit than high pulling torque, have self-locking property preferably, the transmission efficiency height.
The present invention is further described below in conjunction with accompanying drawing:
Fig. 1: structural representation of the present invention.
Fig. 2: A-A sectional view of the present invention.
Fig. 3 is a side view of the present invention.
Among the figure, 1 driving wheel, 2 main shafts, the 3 spiral axle collars, 4 rollers, 5 followers, 6 rollers, 7 supports, 8 supporting frames, 9 frames.
When driving wheel 1 drives 3 rotations of the spiral axle collar, because in the follower 5 a plurality of rollers 4 being installed contacts with each helicoid of the spiral axle collar 3, when support 7 limited the position of followers 5, follower 5 will be under the effect of roller 4, served as that axle rotates along the helicoid of the spiral axle collar 3 with the spiral axle collar.
The supporting wheel of fixing on the frame 98 is provided with respectively more than 3 or 3 according to the size of strength, is equilateral triangle or regular polygon and distributes in the spiral axle collar 3.The inboard fixing rollers 6 of support 7 are for reducing follower 5 when rotating and the surface friction drag of 7 on support.Can be in the inboard setting in pairs of support.
Embodiment 1:
When main shaft 2 drives driving wheels 1 and rotates, driving wheel 1 by with the spiral axle collar 3 in groove in the tooth engagement, drive the spiral axle collar 3 and rotate.The cross section of the spiral axle collar 3 is regular hexagon, and the spiral axle collar 3 is regular hexagon 6 rollers 4 are installed by follower 5 in the follower 5, contact with each helicoid of the spiral axle collar 3 respectively.There are four supporting wheels that are square 3 on frame of being fixed on 9 to support in the spiral axle collar 3.Because follower 5 is stopped by support 7, so axially the spiral axle collar is static relatively for it, along in the helicoid revolution of the spiral axle collar, drive follower 5 rotates around the spiral axle collar 3 at six rollers 4, thereby reaches the purpose of carry-over moment.When driving wheel 1 is static,,, can not make the spiral axle collar 3 backward rotation so act on the reactive torque on the follower 5 because six rollers in the follower 5 according to inclined plane principle, have self-lock ability perpendicular to six helicoids of the spiral axle collar 3.
Embodiment 2:
When main shaft 2 drives driving wheels 1 and rotates, driving wheel 1 by with the spiral axle collar 3 in groove in the tooth engagement, drive the spiral axle collar 3 and rotate.The cross section of the spiral axle collar 3 is regular hexagon, is Octagon in the follower 5, and (Yi Bian can four rolling be installed altogether every a roller is installed) installs 8 rollers 4, contacts with each helicoid of the spiral axle collar 3 respectively.There are five supporting wheels 8 that are regular pentagon on frame of being fixed on 9 to support in the spiral axle collar 3.Because the spiral axle collar 3 rotates, the roller in the follower 5 drives follower and rotates around the spiral axle collar along the helicoid revolution of the spiral axle collar.Thereby reach the purpose of carry-over moment.When driving wheel 1 is static,,, can not make the spiral axle collar 3 backward rotation so act on the reactive torque on the follower 5 because six rollers in the follower 5 according to inclined plane principle, have self-lock ability perpendicular to six helicoids of the spiral axle collar 3.
Embodiment 3:
The cross section of the spiral axle collar 3 is a triangle, and it is corresponding with it that 3 rollers are installed in the follower 5, and all the other are with embodiment 1.Transmission of torque between long wheelbase.Because the roller in the follower is line with the helicoid of the spiral axle collar and contacts, so be fit to transmit than high pulling torque.
