The friction circular plate type gear shifting mechanism comprises a frame and also comprises a driving shaft, a driven shaft and a lead screw; the driven shaft is parallel to the driving shaft; the lead screw is arranged between the driving shaft and the driven shaft; one end of the driving shaft is provided with a detachable first circular plate; one end of the driven shaft is provided with a detachable second circular plate; the first circular plate and the second circular plate are arranged in a parallel eccentric mode; concave pits are distributed in the first circular plate and the second circular plate densely; the lead screw is provided with a transmission wheel which is connected with the lead screw through a sleeve; the sleeve is driven by the transmission wheel to rotate; the sleeve can move along the lead screw; the transmission wheel is connected with the first circular plate and the second circular plate; the transmission wheel can move between the first circular plate and the second circular plate; the outer edge of the transmission wheel is provided with non-slip texture. According to the friction circular plate type gear shifting mechanism, the structure is simple and the continuously variable transmission can be achieved.
Description
Technical field
The present invention relates to transmission technology field, be specifically related to a kind of dot location gear.
Background technique
In lathe, commonly use driving mechanism, what driving mechanism was conventional is gear transmission, but gear transmission because the gear number of teeth is fixed, velocity ratio is fixed, and can not realize electrodeless variable-speed or even multiple variable speed.
Summary of the invention
The invention is intended to provide a kind of dot location gear, to solve the problem that the transmission of prior art middle gear can not electrodeless variable-speed.
Dot location gear in this programme, comprise frame, also comprise driving shaft, the driven shaft parallel with driving shaft and be located at driving shaft, screw mandrel between driven shaft, driving shaft one end is provided with dismountable the first plectane, driven shaft one end is provided with dismountable the second plectane, the first plectane and the parallel eccentric setting of the second plectane, on the first plectane and the second plectane, be all densely covered with pit, screw mandrel is provided with drive wheel, drive wheel is connected by sleeve with screw mandrel, drive wheel sleeve rotates, sleeve can move along screw mandrel, drive wheel connects the first plectane, the second plectane, drive wheel can move between the first plectane and the second plectane, drive wheel outer most edge is provided with anti-skidding lines.
Compared with prior art, advantage of the present invention is: driving shaft drives the first plectane to rotate, the first plectane and drive wheel friction also drive drive wheel to rotate, thereby drive wheel and the second plectane friction drive the second plectane, driven shaft rotates, because drive wheel is connected with sleeve, sleeve can move along screw mandrel again, and first plectane and the parallel eccentric setting of the second plectane, the first plectane is parallel with the second plectane but not on same axis, when drive wheel moves between the first plectane and the second plectane, due to the plectane radius linear velocity difference that do not exist together, also just cause drive wheel speed constantly to change, thereby driven shaft speed is changed, realize stepless change, in addition, on described the first plectane and the second plectane, be all densely covered with pit, not only can increase the first plectane, frictional force between the second plectane and drive wheel, and reduced the kinetic energy rejection of the first plectane and the second plectane, stable and energy-conservation.
Further, between drive wheel and sleeve, be provided with bearing, strengthen mechanism's stability.
