Abstract
The utility model relates to a co-axial two-way lows-speed input and co-axial one-way high-speed output speed increaser, which is applicable to the equipment that input power at time intervals in positive and negative directions and output power at a high speed in single direction. The utility model has the advantages of high rotation efficiency, large carrying capacity, short transmission path, simple production technique, low cost and variation ratio of 30 to 90.
Description
No matter a kind of wheel for inputting of technical field is rotated in the forward, or counterrotating, all turns output wheel, and make the speed increaser that output wheel can only be rotated in the forward.Here Ding Yi forward, promptly identical with output wheel turns to.Otherwise, then be defined as oppositely.
The speed increaser that background technique is general all is unidirectional input, and the speed increaser of unidirectional output can't satisfy special needs, and some equipment needs the forward and reverse input of low speed spaced reciprocally high speed output and exports with input coaxial.And this patent just in time satisfies this special needs.It is the special device of generating usefulness at present.
The wheel for inputting of general K-H type crank-type speed increaser is an out-of-alignment with taking turns out wheel, and this patent has realized that wheel for inputting and output wheel are coaxial.Advantages such as in speed increaser, K-H type crank-type speed increaser has higher transmission efficiency, and axial dimension is little, and drive path is short, and bearing capacity is big, and overload capacity is strong.(see Beijing coloured Zhi Jin design and research institute write mechanical design handbook table 14-6-17).This patent has the advantage of K-H type crank-type speed increaser.The gearbox majority of general speed increaser is a horizonally split, and the gearbox of this patent is an integrated type, thereby can improve precision, reduces production costs.Its velocity ratio is between 30 to 90.
But no matter providing a kind of wheel for inputting, the goal of the invention of this patent rotates all transmission output wheel single direction ground rotations forward or backwards, while wheel for inputting and the coaxial installation of output wheel, and mutual again reversing drive between two wheel for inputting at output wheel two ends.
The object of the present invention is achieved like this:
Because of the two ends of dead axle are fixedly mounted on the frame, its middle part vertical fixing is installed an idler shaft.The inertia cone gear that is slidingly installed on the idler shaft, the left part of stationary axle and the right part bevel pinion shaft that is slidingly installed respectively.The two ends of bevel pinion shaft fixedly mount a cone gear and a wheel for inputting respectively, overrunning clutch of its middle part fixed installation, the outer shroud of overrunning clutch with key respectively with the fixed installation of the endoporus of central gear, and make that turning to of two overrunning clutchs is identical.
Central gear is outer installs two, three or four internal gear ring plate (or being called internal gear) abbreviation ring flat-plate, the middle part of (referring to controlling the k-H type crank-type schematic diagram of mechanism that mechanical design handbook the 3rd certificate 14-381 to the 14-382 page or leaf that total institute writes is studied carefully in gold design by Beijing is coloured) ring flat-plate is an internal gear, opposite transmission with central gear, the two ends of ring flat-plate are bearing holes, and a bent axle is slidingly installed respectively in the bearing hole.Two bent axles are installed in respectively in the bearing hole of two end faces of gearbox.
The two ends of connecting rod and middle part all are bearing holes.The two ends of connecting rod are installed in the end of two bent axles respectively.The middle part of connecting rod is installed on the eccentric eccentric shaft.Eccentric central shaft hole uses Bearing Installation on the axle of transmission main shaft hole.Transmission main shaft hole axle and frame are fixedly installed togather.Eccentric central shaft is fixedly installed togather with the sealing cover of defeated wheel.
The wheel for inputting at two ends can be by the cone gear and the middle mutual backward rotation of inertia cone gear on both sides.During the wheel for inputting backward rotation of one end, can be by the direct transmission central gear of the overrunning clutch backward rotation of this end.At this moment overrunning clutch be in counter-rotational coupled condition; Overrunning clutch when the forward rotation wheel for inputting is in disengaged position, and at this moment the wheel for inputting of the other end is in the backward rotation state, so the direct reversing drive central gear backward rotation of the overrunning clutch of the other end.
The backward rotation of central gear can be passed through ring flat-plate driving crank forward rotation.The forward rotation of two bent axles can be rotated by connecting rod transmission eccentric wheel.Eccentric rotation makes output wheel rotate together.
Therefore, no matter import and become a full member, or backward rotation to rotation, but transmission output wheel forward rotation all.
The schematic diagram of description of drawings embodiments of the invention as shown in Figure 1, it is by forming with lower member: frame 1, stationary axle 2, wheel for inputting 3, eccentric wheel 4, sealing cover 5, output wheel 6, overrunning clutch 7, idle pulley 8, idler shaft 9, central gear 10, cone gear 11, gearbox 12, connecting rod 13, bent axle 14, ring are anti-15, transmission main shaft hole axle 16, bevel pinion shaft 17,
The two ends of embodiment stationary axle 2 are fixedly mounted on the frame 1, and its middle part is vertical installs an idler shaft 9, on the idler shaft 9 with the bearing idle pulley 8 that is slidingly installed.The left part of stationary axle 2 and right part are used Bearing Installation one bevel pinion shaft 17 respectively, the end fixed installation cone gear 11 of bevel pinion shaft 17, the other end fixed installation wheel for inputting 3, middle part interior ring fixed installation strong and overrunning clutch 7.The outer shroud of two single clutch 7 fixedly mounts with the endoporus that turns to identical mode and central gear 10 with key.
Bent axle 14 is slidingly mounted in the bearing hole of two end faces of gearbox 12.Respectively there is a bearing hole at the two ends of connecting rod 13, are installed in the end of two bent axles 14 respectively.Be installed together with the eccentric shaft of eccentric wheel 4 respectively with bearing in the bearing hole at the middle part of connecting rod 13.On transmission main shaft hole axle 16, an end of transmission main shaft hole axle 16 and gearbox 13 fixedly mount the center hole of eccentric wheel 4 with Bearing Installation, and the other end and frame 1 are fixedly installed togather.Eccentric wheel 4 and sealing cover 5 fixed installations, sealing cover 5 and output wheel 6 fixed installations.
The wheel for inputting 3 at two ends is by two cone gears 11 and idle pulley 8 reversing drive mutually.That is to say that when the cone gear bearing of an end is rotated in the forward it is by the bevel pinion shaft counterrotating of the idle pulley transmission the other end; When the bevel pinion shaft counterrotating of an end.The cone gear counterrotating of this end, and by 10 rotations of overrunning clutch backward rotation central gear.Counter-rotational central gear 10 rotates by the internal gear driving crank on the ring flat-plate 15 14, and two connecting rods of bent axle 14 transmissions 13 rotate.(referring to the three-ring speed reducer patent No. 85106692.5)
Two bent axles 14 are by connecting rod 13 transmission eccentric wheels 4 forward rotation.Because eccentric wheel 4, sealing cover 5 is fixedly installed togather with output wheel 6.Therefore, the rotation of eccentric wheel 4 promptly is the rotation of output wheel.As the number of gears Z1 of center gear 10, when the number of teeth of the internal gear of ring flat-plate was Z2, its velocity ratio was: I=-ZI/Z2-Z1. sealing cover (5) seals transmission main shaft hole axle (16) between eccentric wheel (4) and the output opinion (6).Bevel pinion shaft (17) is with sealing between bevel pinion shaft (17) and the stationary axle (2).
