Abstract
The utility model discloses a high-precision transmission steering structure which comprises a main shaft, an output wheel and two sets of driving devices. A bearing seat is fixedly arranged in the middle of the main shaft, and the two sets of driving devices are arranged at the two ends of the main shaft respectively. Each set of driving device comprises a driven gear and a driving element, each driving element is meshed with each driven gear, a shaft sleeve arranged on the main shaft in rotating and sleeved modes is arranged on the end face, facing the bearing seat, of each driven gear in a protruding and stretching mode, and each shaft sleeve extends to the position of the bearing seat and is connected with the bearing seat through a unilateral bearing. According to the high-precision transmission steering structure, unilateral transmission is achieved through the unilateral bearings, multistage reduction transmission is achieved through the driving elements, the driven gears, the main shaft and the output wheel, when the driven gears rotate clockwise or anticlockwise respectively, the main shaft always rotates towards one direction, driving in turns is achieved through the two sets of driving devices, and power can be supplied continuously. The high-precision transmission steering structure simplifies the transmission structure, reduces the size, and is stable and reliable in transmission.
Description
Technical field
The utility model relates to the transmission device technical field, refers in particular to the high precision transmission turning structure.
Background technology
Kickboard Scooter is the novel product form of the another skateboarding after conventional skateboard.existing bi-pedal Kickboard Scooter comprises vehicle frame, rotation is arranged on the handlebar of vehicle frame front end, be arranged on the handle on handlebar, the rear end of vehicle frame is rotatably connected to the rear wheel device, the lower end of handlebar is rotatably connected to front-wheel, the vehicle frame rear end is provided with two and drives pedal, drive pedal front end and vehicle frame hinged, drive pedal and drive the connection rear-wheel device by the high precision transmission turning structure, realize that the unidirectional drive trailing wheel rotates, during use, whole people stands on vehicle frame, bipod is placed on respectively two and drives on pedal, depress the driving pedal with bipod respectively and just can drive the trailing wheel rotation by the high precision transmission turning structure.The high precision transmission turning structure design of existing pedal scooter is unreasonable, and complex structure takies volume large, and transmission is not steady, and safety factor is low.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of simplification drive mechanism, minimizing volume, stable drive failure-free high precision transmission turning structure for the deficiency of prior art existence.
For effectively addressing the above problem, the technical scheme that the utility model is taked is as follows:
The high precision transmission turning structure includes main shaft, is arranged on the output wheel on main shaft, two groups of actuating devices, and the middle part of main shaft is fixed with bearing seat, and two groups of actuating devices are separately positioned on the two ends of main shaft; Every group of actuating device includes turning set and is located at driven gear on main shaft, driven by external force and drive the driver element that driven gear rotates, driver element and driven gear engagement, driven gear protrudes out turning set towards the end face of bearing seat and is located at axle sleeve on main shaft, and axle sleeve extends to the bearing seat place and is connected with bearing seat by unilateral bearing.
Especially, described output wheel is fixed by socket on bearing seat.
Especially, described output wheel is sprocket wheel or gear.
Especially, the two ends towards two groups of actuating devices of described bearing seat offer respectively circular groove, and axle sleeve extends in circular groove.
Especially, the two ends of the described main shaft limited location nut that is threaded respectively.
Especially, described driver element is gear or tooth bar.
the beneficial effects of the utility model: the high precision transmission turning structure that the utility model provides, include main shaft, be arranged on the output wheel on main shaft, two groups of actuating devices, the middle part of main shaft is fixed with bearing seat, and two groups of actuating devices are separately positioned on the two ends of main shaft, every group of actuating device includes turning set and is located at driven gear on main shaft, driven by external force and drive the driver element that driven gear rotates, driver element and driven gear engagement, driven gear protrudes out turning set towards the end face of bearing seat and is located at axle sleeve on main shaft, axle sleeve extends to the bearing seat place and is connected with bearing seat by unilateral bearing, the utility model is realized single-direction transmission by unilateral bearing, and pass through driver element, driven gear, main shaft and output wheel are realized the multi-stage speed-reducing transmission, when driven gear clockwise rotates respectively or rotates counterclockwise, main shaft all always only rotates to a direction, drive in turn by two groups of actuating devices, can sustainable supply power, the utility model is simplified drive mechanism, reduce volume, stable drive is reliable.
Below in conjunction with accompanying drawing, the utility model is elaborated.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further described, as shown in Figure 1, high precision transmission turning structure of the present utility model, include main shaft 1, be arranged on the output wheel 2 on main shaft 1, two groups of actuating devices 4, the middle part of main shaft 1 is fixed with the two ends that 3, two groups of actuating devices 4 of bearing seat are symmetricly set on main shaft 1; Every group of actuating device 4 includes turning set and is located at driven gear 41 on main shaft 1, driven by external force and drive the driver element 42 that driven gear 41 rotates, driver element 42 and driven gear 41 engagements, driven gear 41 protrudes out turning set towards the end face of bearing seat 3 and is located at axle sleeve 43 on main shaft 1, and axle sleeve 43 extends to bearing seat 3 places and is connected with bearing seat 3 by unilateral bearing 5.
The utility model is realized single-direction transmission by unilateral bearing 5, and realize the multi-stage speed-reducing transmission by driver element 42, driven gear 41, main shaft 1 and output wheel 2, when driven gear 41 clockwise rotates respectively or rotates counterclockwise, main shaft 1 all always only rotates to a direction, drive in turn by two groups of actuating devices 4, can sustainable supply power, the utility model is simplified drive mechanism, is reduced volume, stable drive is reliable.
The utility model is not limited to above-mentioned embodiment, and all employings and the utility model analog structure are realized all modes of the utility model purpose, all within protection domain of the present utility model.
