Description
Technical field
The utility model relates to a kind of speed change gear of dynamic power machine, relates in particular to a kind of electrodeless variable-speed case.
Background technique
The electrodeless variable-speed case adopts driving belt and the variable driven wheel of the working diameter incompatible transferring power that matches, and can realize continuously changing of velocity ratio, thus the optimum Match of the power train of obtaining and engine operating condition.Common stepless speed variator has hydraulic mechanical type stepless speed variator and metal band type stepless speed variator, being applied in the speed change gear of various machinery and transmission of power at present, is the gear type structure mostly, and running is meshing with each other during work done, exist complex structure, noise is big, the defective that working life is short.
The model utility content
The purpose of this utility model provides a kind of electrodeless variable-speed case, and is simple in structure, use easy to operate, low noise, long service life, economic security.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of electrodeless variable-speed case, comprise housing, the two ends of described housing are respectively equipped with initiatively splined shaft and drive splines axle, initiatively the middle part of splined shaft is equipped with initiatively transmission pulley, the middle part of drive splines axle is provided with the branch belt pulley body, against tension spring, divides belt pulley body to be connected with the active transmission pulley by the vee belt between branch belt pulley body and the housing, the middle part of vee belt is provided with Idle wheel, and Idle wheel is connected with regulating handle by driving mechanism.
The beneficial effects of the utility model are: simple in structure, use easy to operate, low noise, long service life, economic security.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the internal structure schematic representation of the described a kind of electrodeless variable-speed case of the utility model embodiment.
Among the figure:
1, housing; 2, active splined shaft; 3, drive splines axle; 4, active transmission pulley; 5, divide belt pulley body; 6, vee belt; 7, tension spring; 8, Idle wheel; 9, regulating handle.
Embodiment
As shown in Figure 1, the described a kind of electrodeless variable-speed case of the utility model embodiment, comprise housing 1, the two ends of described housing 1 are respectively equipped with initiatively splined shaft 2 and drive splines axle 3, initiatively the middle part of splined shaft 2 is equipped with initiatively transmission pulley 4, the middle part of drive splines axle 3 is provided with branch belt pulley body 5, divide between belt pulley body 5 and the housing 1 against tension spring 7, divide belt pulley body 5 to be connected with active transmission pulley 4 by vee belt 6, the middle part of vee belt 6 is provided with Idle wheel 8, and Idle wheel 8 is connected with regulating handle 9 by driving mechanism.
During concrete the use, initiatively transmission pulley 4 passes to branch belt pulley body 5 with power by vee belt 6, divide belt pulley body 5 to come closer at the pressure of tension spring 7, pull regulating handle 9 and move Idle wheel 8, adjust the elasticity of vee belt 6, change the friction radius of vee belt 6 on minute belt pulley body 5 wheel rims, i.e. the may command rotational velocity.
