Abstract
The utility model relates to a sheet type mechanical speed-changing deviator which primarily solves the problems that the existing speed-changing deviators have complicated structure, heavy weight and difficulty in being fabricated to be sheets. The mechanical speed-changing deviator is characterized in that a driving wheel is disk type, the upper part of the driving wheel is provided with a layer of internal gear teeth and a layer of external gear teeth that are concentrical and adjacent, and the driving wheel can be respectively engaged with the internal and the external gear teeth through a control mechanism so as to achieve speed changing and direction deviating. The utility model has the characteristics of simple structure, portability and sheet type, which is difficult for the existing speed-changing deviators to realize.
Description
The utility model belongs to the adjustable device of speed and direction changing of machine driven system.
The speed and direction changing device of existing mechanical transmission system, as automotive transmission, comprise that two axles that are provided with a plurality of gears cooperatively interact, reach the purpose of speed and direction changing, its deficiency is: structure is single and complicated, heavy, can not make chip, and in use make troubles, using scope also is restricted, as is not suitable for bicycle etc.
The purpose of this utility model be exactly provide at above-mentioned deficiency a kind of simple in structure, volume is little, in light weight, the speed and direction changing device that can be made into chip.
Technical solution of the present utility model is: a kind of mechanical speed change diverter, it is characterized in that: the driving wheel that comprises a band axis, this driving wheel is provided with external tooth teeth and one deck larger-diameter internal tooth teeth of one deck than minor diameter with one heart, and the internal tooth teeth are adjacent with the external tooth teeth.The driving wheel and the control mechanism thereof that can cooperate with the inside and outside teeth of this driving wheel respectively.
Driving wheel in the utility model technical solution is the disk that is provided with circular groove, is respectively equipped with internal tooth teeth and external tooth teeth on the bi-side of this circular groove.
Driving wheel in the utility model technical solution can also be to comprise a hollow external tooth gear and the larger-diameter hollow internal-gear than minor diameter, and this external tooth gear and internal-gear are connected propping up of band axis with one heart and add.
Control mechanism in the utility model technical solution can be to be made of eccentric shaft, swing arm.
Control mechanism in the utility model technical solution can also be to be made of L shaped axle, tuning knob.
Control mechanism in the utility model technical solution can also be to be made of axle, spring and tuning knob.
Control mechanism in the utility model technical solution can also be to be made of axle, gliding mass.
The utility model is owing to adopt the disc type driving wheel, and is provided with two-layer concentric, adjacent inside and outside teeth on this driving wheel, control mechanism can adjust make driving wheel respectively with this inside and outside teeth engagement, make driving wheel obtain different rotating speeds and turn to.When the engagement of the less external tooth of diameter on driving wheel and the driving wheel, driving wheel obtains less rotating speed, and with the switched in opposite of driving wheel; When the engagement of diameter is bigger on driving wheel and the driving wheel internal tooth, driving wheel obtains bigger rotating speed, and identical with turning to of driving wheel.Because the utility model integral body can be made into chip, compare with existing speed and direction changing device, have that volume is little, in light weight, simple in structure, the characteristics of applied range.Be specially adapted to bicycle.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model embodiment 1 a structure sectional view, and book extract accompanying drawing as an illustration;
Fig. 2 is the utility model embodiment 2 a structure sectional view;
Fig. 3 is the structure sectional view of tuning knob among Fig. 2;
