Abstract

The utility model discloses a new engine which is composed of cylinders 1, pistons 2, a spiral shaft 3, a guide slot 4, a rotor gear 5, an intake valve 6, an exhaust valve 7, an oil spraying valve 8, etc. Two cylinders are oppositely arranged, and two pistons are respectively arranged in the cylinders. The two pistons alternately apply work to drive the rotor gear 5 to transmit power outwards. The engine has the advantages of small size, high mechanical efficiency, etc.

Description

The helical rotor motor

The utility model is a kind of mechanical device, promptly a kind of helical rotor motor.

At present, reciprocating engine is used commonplace.This motor is by piston to-and-fro motion in cylinder body, but compression ignite fuel vapor and work done.It is air-breathing that but this motor needs to carry out more, compression, and work done, strokes such as exhaust, wherein the stroke of work done only accounts for 1/4, therefore needs a plurality of cylinder body interoperations, like this, has both increased the volume of motor, has increased friction again, has reduced mechanical efficiency.

The purpose of this utility model is that a kind of volume of development is less, and expansion space stroke is more, the motor that mechanical efficiency is higher.

Above-mentioned purpose is realized by following technological scheme: this motor also is made up of cylinder, piston and air feed oil supplying device, different is, there are two along same shaft axis cylinder staggered relatively, a piston is arranged in each cylinder, the screw axis that is connected between the two-piston has a center to be provided with spiral hole between two cylinders, is enclosed within the exteranl gear on the screw axis, piston reciprocatingly slides along cylinder, and screw axis promptly drives exteranl gear and back and forth rotates.

Each is meshed said exteranl gear both sides with a secondary gear, establishes circular hole and unidirectional ratchet in the secondary gear, is provided with single direction ratchet in the circular hole, is fixed with transmission shaft on the single direction ratchet, the transmission shaft end power output gear that is connected.

The motor that adopts such scheme to make, when the reciprocating motion of the pistons in the cylinder, each stroke all can drive the exteranl gear work done.Thereby it is little, simple in structure to have a volume, and energy loss is few, the advantage that mechanical efficiency is high.

Introduce a kind of embodiment below in conjunction with accompanying drawing.

Fig. 1 is the plan view of present embodiment.

Fig. 2 is a present embodiment gearing plan view, and Fig. 3 is its left view, and Fig. 4 is its plan view.

Have among the figure: cylinder 1, piston 2, screw axis 3, guiding groove 4, exteranl gear 5, intake valve 6, exhaust valve 7, oil spout door 8, secondary gear 9, couple axle 10, power output gear 11, ratchet 12, ratchet 13, frame 14 etc.

As seen from the figure, this motor has two cylinders 1, a piston 2 is arranged in each cylinder, a screw axis 3 is connected between the two-piston, screw axis is provided with guiding groove 4, between two cylinders, an exteranl gear 5 is arranged, the endoporus of exteranl gear 5 is the spiral hole that match with screw axis, behind piston compression ignite oil gas, the beginning expansion space stroke, and another piston begins compression stroke, when last piston expansion space stroke finishes, the intake valve 6 and the exhaust valve 7 of this cylinder are opened, enter fresh air, scavenge, close then.At this moment, the piston of another cylinder is compression ignite oil gas, the beginning expansion space stroke, and like this, two pistons replace work done, and under the effect of screw axis 3, exteranl gear 5 back and forth rotates, output power.

As seen from Figure 2,, respectively there is a gear 9 under the drive of exteranl gear 5, back and forth to rotate, is called secondary gear in the exteranl gear both sides.The endoporus of secondary gear engages by ratchet 13 and single direction ratchet 12, and single direction ratchet 12 links to each other with power output gear by transmission shaft 10.Secondary gear has the rotation of a direction to pass to power output gear by single direction ratchet in back and forth rotating, and a pair of secondary gear replaces transmission, can make two power output gears that are meshed do directed the rotation, thereby outwards transmit power.

In said apparatus, working principle such as the air inlet of cylinder, exhaust, oil spout and parts are prior art, do not draw among the figure.

In the time of necessary, can the motor more than two groups be grouped together, be designed to bigger type.
