Abstract

The utility model discloses a dual engine which comprises two engines. The utility model is characterized in that a crank shaft (3) of one engine (1) is connected with a crank shaft (12) of the other engine (2) into a whole through a shaft connector, and the two engines (1 and 2) connected in series are fixed on a support seat (14). The utility model is formed by using the existing two single-cylinder four-stroke engines, having the advantages of increasing the output power of the engine, reducing the production cost compared with a high power engine of the same power and protecting the economic interests of manufacturers and users.

Description

The twin motor

Technical field

The utility model relates to a kind of motor, particularly a kind of twin motor that is used for high-power gasoline engine generator group.

Background technique

Along with the development that domestic industry is produced, power supply in short supply become an insurmountable in a short time difficult problem, and high-power gasoline engine generator group is ready-made to be hot product.And common 10KW gasoline engine generator group mostly is imported product on the present Domestic market, and its manufacture cost is too high, costs an arm and a leg, and has increased user's economic burden, thereby a kind of power of market demand is big, the motor of economical and practical again gasoline engine generator group.

Summary of the invention

The purpose of this utility model provides a kind of twin motor, and it is combined by two single-cylinder four-stroke engines of low cost of manufacture, and the power of motor is greatly improved.

The purpose of this utility model is achieved in that and comprises two motors, and the bent axle of a motor connects as one by the bent axle of coupling and another motor, and two motors of polyphone are fixed on the bearing.

Owing to adopted such scheme, two motors are fixedly connected on the bearing, the bent axle concentric of the bent axle of a motor by coupling and another motor is rigidly connected and is one, one of them bent axle is with respect to 360 ° of another crankshaft rotating, make continuous two to start function to finish synchronous intersection work done, increase the output power of motor.On coupling, be fixedly connected with fan, solved the heat dissipation problem of motor and the installation question of two machines polyphone aft-fan simultaneously, guaranteed the compact structure of motor.

The utility model utilizes existing two single-cylinder four-stroke engines to form, and has both made the output power of motor obtain increasing, and the cost of production than the high power engine of equal-wattage is low again, and manufacturer and user's economic benefits are protected.The utility model effect is seen following laboratory data:

With two 188F engine tests is example

Can find that by above data the utility model twin engine power can reach more than the 14KW.By connecting generator useful horsepower is 70% calculating, can drive the 10KW motor.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structure diagram of joint of the present utility model.

Embodiment

Referring to Fig. 1, Fig. 2, single-cylinder four-stroke engine 1, the 2 usefulness bolton of two polyphones are provided with beam between motor 1,2 and the bearing 14 on a bearing 14.The left bent axle of motor 1 is fixedly connected with fan 15, and the right bent axle 3 of motor 1 is circumferentially fixedlyed connected with flanged pin half-coupling 4 by flat key 5; The left bent axle 12 of motor 2 with respect to 360 ° of right bent axle 3 rotations of motor 1 after, circumferentially fixedly connected with flanged pin half-coupling 10 by flat key 11, flat key 5,11 is positioned on the same axis.Two half-couplings 4,10 are fitted, and fan 7 is clipped between two half-couplings 4,10, are used for the forced air cooling heat radiation.The flange of two half-couplings 4,10 connects the location with locating stud 8, locating stud 8 is provided with axle center hole, and bolt 9 passes locating stud 8, and is fastening with nut 6, the other end of two half-coupling 4,10 flanges is fastening with bolt 13, bent axle 3,12 concentrics of two motors is rigidly connected is one.The end that the right bent axle 3 of motor 1, the left bent axle 12 of motor 2 and half-coupling 4,10 connect is consistent cylindrical of diameter, so that processing and assembling.

During engine operation, two 1,2 while of motor ignition triggers, the output power of motor 1 is through the bent axle output of motor 2, because the bent axle of two motors rotates synchronously, but work cycle is intersected, so form intersection work done synchronously, makes output power obtain increasing.
