Abstract
The utility model provides a crankshaft driving device, comprising a rotary shaft 3, a bearing used for supporting the rotary shaft 3, and a bearing seat 4, wherein, one end of the rotary shaft 3 is connected with a piston rod 1 through a connecting rod 2. The utility model is characterized in that the rotary shaft 3 is composed of a main shaft 3 and an auxiliary shaft 8 with different axes, and the main shaft 3 and the auxiliary axis 8 are connected by sliding parts. In the operating process, the main and the auxiliary arms are mutually the long and the short arms; thereby, when a piston applies work, the output torque is increased. The work efficiency can be improved, the energy consumption is reduced, and the interval combustion engine performance is improved. The utility model is suitable for intermittent internal combustion engines of a car, a motorcycle, etc. A plurality of groups of the utility model can be connected for using, and in addition, when the utility model is used for a bicycle, the labor can be greatly saved.
Description
The utility model relates to a kind of transmission device, especially a kind of crankshaft gear that can increase moment of torsion.
Because piston gear can make linear reciprocating motion be transformed into and rotatablely move, and simple in structure, superior performance, cost is low, therefore, is widely used on the internal-combustion engine of automobile, motorcycle.And existing transmission device is coaxial output, can not change its output torque, changes output torque and then will rely on gear-box, but must be the change that exchanges moment of torsion with the change of rotating speed for.
It is a kind of with the crankshaft gear that can improve output torque under the speed conditions that the purpose of this utility model is to provide.
Concrete scheme of the present utility model is: it comprises rotatingshaft 3, supports the bearing and the bearing support 4 of rotatingshaft 3, wherein an end of rotatingshaft 3 links to each other with piston rod 1 by connecting rod 2, it is characterized in that rotatingshaft 3 is made of the main shaft 3 and the countershaft 8 of two different shaft axiss, and be connected by slider between main shaft 3 and the countershaft 8.Described slider comprises the principal arm 5 that links to each other with main shaft 3, with the auxiliary 7 that links to each other with countershaft 8, and the slide block 6 that connects two arms.Wherein an end of slide block 6 is located at by bearing 10 on the minor axis 11 that links to each other with auxiliary, and the other end is that the collar 12 directly is placed on the principal arm 3, so that in rotation process, principal arm is slided in slide block.
Its working procedure is: when piston 1 acting, driving main shaft 3 by connecting rod 2 rotates, the principal arm 5 that links to each other with main shaft 3 also rotates thereupon, because the desaxe of main shaft and countershaft, cause principal arm 5 shorter than auxiliary 7, and half cycle before driving auxiliarys 7 and countershaft 8 and rotate by slide block 6 by principal arm 5, output torque is increased; When piston carries out other stroke, when just main shaft turns over non-acting angle, because the desaxe of main shaft and countershaft, cause principal arm 5 longer than auxiliary 7, under the inertial force effect, drive principal arm 5 and main shaft 3 rotation second half by auxiliary 7 by slide block 6, thereby form an operation cycle.
Advantage of the present utility model is: owing to be provided with the major and minor arm that is slidingly matched between two eccentric shafts, make it length arm each other in the course of the work, thereby the moment of torsion of output is increased, help increasing work efficiency, cut down the consumption of energy, improve engine performance.The utility model is applicable to intermittent type internal-combustion engines such as automobile, motorcycle, and can organize to connect more and use, and its effect is obvious.Other is used on the bicycle very laborsaving.
Fig. 1 is the structural representation of the utility model:
Fig. 2 is another structural representation of the utility model;
Fig. 3 is the slide block structure schematic representation of the utility model.
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is piston rod, and the one end links to each other with piston, the other end links to each other with connecting rod 2, and 2 is connecting rod, links to each other with main shaft 3,3 is main shaft, 4 is bearing and bearing support, and being used for supports main shaft 3,5 is principal arm, be connected with main shaft 3,6 is slide block, and the one end is cylindrical, in be provided with bearing 10, place on the minor axis 11 by this bearing 10, the other end of slide block is the collar 12, and main shaft 3 is located in this collar 12, and 7 is auxiliary, be connected with an end of countershaft 8, the middle part of auxiliary 7 is fixed with minor axis 11, and the other end of countershaft 8 is connected with retarder, and supports by bearing and bearing support 9.
Claims (3)
1, a kind of crankshaft gear, the bearing and the bearing support 4 that comprise rotatingshaft 3, support rotatingshaft 3, wherein an end of rotatingshaft 3 links to each other with piston rod 1 by connecting rod 2, it is characterized in that rotatingshaft 3 is made of the main shaft 3 and the countershaft 8 of two different shaft axiss, and be connected by slider between main shaft 3 and the countershaft 8.
2, transmission device according to claim 1 is characterized in that described slider comprises the principal arm 5 that links to each other with main shaft 3, with the auxiliary 7 that links to each other with countershaft 8, and the slide block 6 that connects two arms.
