Abstract
The utility model relates to a transmission device for an oil pump of a two-stroke engine. Crucially, the transmission device comprises a driving wheel (2) arranged on a left crank case (8) of an engine and connected with a crankshaft (1) of the engine, and a driven wheel (4) arranged on the left crank case (8) of the engine and connected with an oil pump mandrel (3) of the engine, wherein the driving wheel (2) is connected with the driven wheel (4) through a belt (5). The transmission device for the oil pump has the advantages of small abrasion, small working noise, stable transmission and long service life.
Description
Technical field
The utility model relates to a kind of transmission device of oil pump.
Background technique
Existing two stroke engine generally adopts chain-driven or gear transmission to come the power of transfer machine oil pump, though such structure can satisfy general usability, but when using separated type lubricated, the lubricating condition of this transmission device is just relatively more abominable, therefore chain or gear ratio are easier to be worn, thereby produce the big shortcoming of noise, and transmission is not steady yet, working life is also shorter.
The model utility content
The purpose of this utility model is to provide a kind of two stroke engine oil pump transmission device that weares and teares little.
The purpose of this utility model is achieved through the following technical solutions: a kind of two stroke engine oil pump transmission device is characterized in that: this transmission device comprises on the left crankcase that is arranged on motor and the driving wheel that is connected with the bent axle of motor; Be arranged on the left crankcase of motor and the follower that is connected with the oil pump mandrel of motor; Described driving wheel is connected by belt with described follower.
Described driving wheel can be connected by spline with described bent axle.
Described follower can be connected with described oil pump mandrel by square hole.
For further improving the efficient and the stationarity of transmission, the outer surface of described driving wheel and described follower is provided with tooth; Described belt is a synchronous belt.
The beneficial effects of the utility model are: because driving wheel and follower adopt the bel-drivenn mode, even therefore under the condition that separated type is lubricated, the wearing and tearing of oil pump transmission device are also smaller, thereby reduced the operating noise of motor; Further, because the outer surface of driving wheel and follower is provided with tooth, belt is a synchronous belt, so stable drive, and long service life.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation.
Embodiment
Embodiment 1: as shown in Figure 1, and the driving wheel 2 that a kind of two stroke engine oil pump transmission device, this transmission device comprise on the left crankcase 8 that is arranged on motor and be connected by spline 6 with the bent axle 1 of motor; The follower 4 that is arranged on the left crankcase 8 of motor and is connected by square hole 7 with the oil pump mandrel 3 of motor; Described driving wheel 2 is connected by belt 5 with described follower 4; The outer surface of described driving wheel 2 and described follower 4 is provided with tooth; Described belt 5 is a synchronous belt.
Bent axle 1 passes through spline 6 transferring power with driving wheel 2, driving wheel 2 is given follower by synchronous belt 5 with transmission of power, follower 4 is connected transmission by square hole 7 and rotates with oil pump mandrel 3, reach the effect of oil pump with the engine crankshaft interlock, and promptly the oil pump rotating speed is directly proportional with speed of crankshaft.
The utility model includes but not limited to above embodiment; as long as two stroke engine oil pump transmission device; comprise the driving wheel that is connected with bent axle; the follower that is connected with the oil pump mandrel; described driving wheel is connected by belt with described follower, all drops in the protection domain of the present utility model.
Claims (4)
1, a kind of two stroke engine oil pump transmission device is characterized in that: this transmission device comprises the driving wheel (2) that the left crankcase (8) that is arranged on motor is last and be connected with the bent axle (1) of motor; Be arranged on the follower (4) that the left crankcase (8) of motor is gone up and is connected with the oil pump mandrel (3) of motor; Described driving wheel (2) is connected by belt (5) with described follower (4).
2, two stroke engine oil pump transmission device as claimed in claim 1 is characterized in that: described driving wheel (2) is connected by spline (6) with described bent axle (1).
3, two stroke engine oil pump transmission device as claimed in claim 1 is characterized in that: described follower is connected with described oil pump mandrel (3) by square hole (7).
