Specific implementation mode：

In order to clarify the technical characteristics of the invention, below by specific implementation mode, and its attached drawing is combined, to this reality It is described in detail with novel.

As shown in Figs 1-4, a kind of rigid stepless speed change device, including a setting are connected in gearbox with input shaft 1 The output panel 4 for the setting that is connected with output shaft 3, input disc 2 and output panel 4 is arranged in gearbox in the input disc 2 and one of setting Concentric setting is respectively symmetrically equipped with several sliding slots 5 along the setting of its even circumferential, each on input disc 2 and output panel 4 Sliding slot 5 is arranged respectively along the radial direction on input disc 2 and output panel 4, and movable sleeve is distinguished outside input shaft 1 and output shaft 3 Disk 6 is fixed equipped with one, a gear lever 7 is respectively equipped in each sliding slot 5 of output panel 2, the inner end of every gear lever 7 is outside It is pierced by the sliding slot 5 of output panel 4, and is connected on the fixation disk 6 of 3 side of output shaft, and the circumferencial direction for being fixed along it disk 6 is uniform Arrangement setting, the outer end of every gear lever 7 is pierced by 2 sliding slot 5 of input disc being oppositely arranged with 4 sliding slot 5 of output panel outward, and supports The circumferencial direction for being connected on the fixation disk 6 of 1 side of input shaft, and being fixed along it disk 6 is uniformly arranged setting, the gear lever 7 Setting, and V-shaped setting are gathered in middle part to the central axial direction of output shaft 3, and the position that 7 middle part of the gear lever is gathered is located at Between input disc 2 and output panel 4.

The position that 7 middle part of the gear lever is gathered is not in contact with each other.

Gather at 7 middle part of gear lever and is fixed with a connection ring 8 on position.The setting of connection ring 8 can increase gear lever Whole stability, effectively avoids gear lever 7 from being deformed upon in rotation process, improves the service life of gear lever 7.

It is respectively symmetrically connected with a connecting shaft 9, two companies in the opposite side medium position of input disc 2 and output panel 4 Spindle 9 and input disc 2,4 concentric setting of output panel, the free end of two connecting shafts 9 passes through bearing 10 and a fixed block respectively 11 are connected, and fixed block 11 and connecting shaft 9 are not in contact with gear lever 7.The gap for gathering position among gear lever 7 is respectively greater than The corresponding cross-sectional sizes of connecting shaft 9 and fixed block 11, during the work time, the centre of gear lever 7, which gathers position, smoothly to wear Connecting shaft 9 and fixed block 11 are crossed, input disc 2 drives 9 turns of the connecting shaft of 11 both sides of fixed block with output panel 4 in rotation process Dynamic, connecting shaft 9 can play the role of stable connection to input disc 2 and output panel 4, and input disc 2 is made to be rotated with output panel 4 Position offset, safety and stability are not susceptible in journey.

It is arranged with a wear-resisting ring 12 respectively on the position that two fixed disks 6 are in contact with input shaft 1, output shaft 3.In work During work, friction is will produce between fixed disk 6 and input shaft 1, output shaft 3, all to input shaft 1, output shaft 3 and fixed disk 6 Abrasion is will produce, wear-resisting ring 12 can effectively reduce wear problem, improve the service life of parts.

In use, when original state, the gear lever 7 between two fixed disks 6 is located at attached position shown in Fig. 3, input disc 2 The center for the positional distance input disc 2 being in contact with gear lever 7 in sliding slot 5 is nearest, connects with gear lever 7 in 4 sliding slot 5 of output panel The center of tactile positional distance output panel 4 is farthest, and the small diameter of input disc 2 drives the larger diameter rotation of output panel 4, output Axis 3 be in the slow-speed of revolution, high power output state；In accelerator, 7 position of gear lever in attached drawing 3 is gradually from right to left Mobile, the position being in contact with gear lever 7 in 2 sliding slot 5 of input disc is gradually distance from the center of input disc 2,4 sliding slot of output panel The position being in contact with gear lever 7 in 5 is gradually drawn close to the center of output panel 4, and the gear lever 7 in 2 sliding slot 5 of input disc rotates directly Diameter gradually increases, and the gear lever 7 in 4 sliding slot 5 of output panel rotates diameter and is gradually reduced, and the rotating speed of output shaft 3 increases therewith.When turn When speed reaches highest, gear lever 7 is located at attached position shown in FIG. 1, the position being in contact with gear lever 7 in 2 sliding slot 5 of input disc 2 center of distance input disk is farthest, and 4 center of positional distance output panel being in contact with gear lever 7 in 4 sliding slot 5 of output panel is nearest, defeated The larger diameter for entering disk 2 drives the small diameter rotation of output panel 4, output shaft 3 to be in high-speed state.

During the work time, position is gathered in the centre of gear lever 7 can pass through connecting shaft 9 and fixed block 11, fixed Block 11 and connecting shaft 9 are not in contact with each other with gear lever 7 respectively；Be arranged gear lever 7 gather connection ring 8 at position also not with connect Axis 9, fixed block 11 contact, and can ensure the smooth movement of the gear lever 7 in work process.Input disc 2 is being rotated with output panel 4 The connecting shaft 9 of 11 both sides of fixed block is driven to rotate in the process, connecting shaft 9 can play stable connection to input disc 2 and output panel 4 Effect, so that input disc 2 and output panel 4 is not susceptible to position offset, safety and stability in rotation process.During the work time, Friction is will produce between fixed disk 6 and input shaft 1, output shaft 3, mill can all be generated to input shaft 1, output shaft 3 and fixed disk 6 Damage, wear-resisting ring 12 can effectively reduce wear problem, improve the service life of parts.

This technology reasonable design is securely and reliably totally different from traditional gear drive and steel band type electrodeless variable-speed technology, Many complicated parts are not needed, the gear of gearbox after additions, need not increase a large amount of parts, it is only necessary to will The radius of gyration of gear lever 7, input disc 2, output panel 4 in this technology increases therewith, without increasing part, overcomes skill Problem in art and cost, and it is greatly saved cost, and also the steel being different from steel band type electrodeless variable-speed technology rub It wipes and is driven, the contact area between the parts that gear is related in this technology greatly reduces, and will be generated in transmission process Frictional force be effectively controlled in zone of reasonableness, can realize continuously smooth speed change.

Above-mentioned specific implementation mode cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.

Place is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
