Description

rotary cylinder engine

The utility model relates to an engine, in particular to a cylinder rotary engine.

The traditional tandem cylinder engine has several cylinder devices arranged in tandem on different cross-sections of the main shaft, and the crank-link mechanism is used to change the reciprocating motion of the piston into the rotary motion of the crankshaft. On the one hand, the effective utilization rate of the external volume of the engine is relatively low; Increasing the engine speed will increase the inertial force of the reciprocating parts, thereby increasing the load on the crankshaft bearing and other parts and affecting the service life. At the same time, the normal operation of the valve mechanism will also be damaged. Compact, and the second is that it is difficult to further speed up.

The purpose of this utility model is to overcome above-mentioned defect, provide a kind of not only compact in structure, but also can increase speed than prior art rotary cylinder engine.

The purpose of this utility model is achieved in that:

A rotary cylinder engine, including an engine block, a main shaft, a gas distribution device, a cylinder and its piston, a connecting rod, and a crank, is characterized in that several cylinders are arranged side by side on different circumferential surfaces perpendicular to the main shaft of the engine Crank connecting rod group, cylinder crank connecting rod group is composed of more than two sets of cylinders and connecting rods arranged on the circumferential surface or fan surface; one end of the connecting rod is connected with the piston, and the other end is connected with a ring bracket integrated with the crank. One of the main connecting rods is fixedly connected with the ring bracket, and the rest are movable hinges. The arrangement position of the connecting rods on the ring bracket is corresponding to the arrangement of the cylinders on the circumferential surface, and the crank is fixedly connected with the main shaft.

Another improvement of the utility model is that all the connecting rods are hinged with the ring bracket, and a one-way rotating guide device composed of a sliding sleeve and a sleeve rod is arranged between a pair of cylinders and connecting rods. The rod passes through the sliding sleeve, and any one of the sliding sleeve and the sleeve rod is fixed on the cylinder body, and the other is fixed on the annular bracket, and the two are slidably matched.

Cylinders and connecting rods are distributed at equal angles on the circumferential surface or in one of its sectors.

The further improvement of the utility model is that the valve mechanism corresponding to the number of cylinders contained in the gas distribution device is a plunger type valve mechanism.

Due to the adoption of the above structure, multiple cylinders and crank-connecting rod groups can be arranged on a circumferential surface or a circular sector, and several cylinders, crank-connecting rod groups can be arranged on multiple circumferences parallel to the main axis. The volume of the engine gallery is more compact. Under the same conditions, the length of the engine is shorter, the crankshaft is also shortened accordingly, the inertial force is reduced, and the inertial couple can be better balanced, and the torsional vibration is lighter, which makes the engine run more smoothly. smooth.

The utility model is described in more detail below in conjunction with accompanying drawings 1 to 5 and embodiments.

Fig. 1 is a schematic diagram of the block arrangement of a rotary cylinder engine with four cylinders on one circumference.

Fig. 2 is a schematic diagram of the rotary engine arranged in a single row in Fig. 1 .

Fig. 3 is a schematic diagram of the axial arrangement of the cylinder crank-connecting rod groups 2 of the twin-row parallel cylinder engine (the lower part of the cylinder block is omitted).

Fig. 4 is a schematic diagram of a cylinder block arrangement structure of a rotary cylinder engine with two cylinders arranged in a V shape on a circular sector.

Fig. 5 is a schematic diagram of the structure of the plunger valve.

Example 1:

A kind of rotary cylinder engine (see Fig. 1, Fig. 2) arranged in a single row, in the cylinder block 1, on the circumferential surface centered on the engine main shaft 10, four sets of cylinders 2 and connecting Rod 4, cylinder 2 is fixedly connected with cylinder block 1, piston 3 in cylinder 2 is hinged with one end of connecting rod 4, and the other end of three of them is connected with ring bracket 6 hingedly, and the other connecting rod 4 The corresponding end of the connecting rod 7 is fixedly connected with the ring bracket 6 as the main connecting rod 7, and it has a one-way rotation guiding effect like a common engine. Mode is corresponding, and the connection of crank 5 and main shaft is promptly fixed as a whole with common motor, and 20 is the flywheel that links to each other with motor among Fig. 2.

Example 2:

Described tandem cylinder engine (referring to Fig. 3) is on the basis of embodiment 1, is provided with a cylinder crank-connecting rod group 12 side by side on another circumferential surface parallel to parallel on the same main shaft, i.e. two concentric Four sets of cylinders 2, connecting rods 4, annular brackets 6 and cranks 5 are respectively quartered on the circumferential surface of the cylinder, which is equivalent to two rotary engines in embodiment 1 arranged in tandem along the main shaft.

Embodiment 4: a rotary cylinder engine with two cylinders arranged in a V shape on a circular sector.

The difference from the above embodiment is that all the connecting rods 4 are hinged with the annular bracket 6, another sliding sleeve 8 is fixedly connected with the annular bracket 6, the sleeve rod 9 is hinged with the cylinder body 1, and the sleeve rod 9 passes through the sleeve Inside the pipe 8, the effect of the sleeve rod 9 and the sleeve pipe 8 is to replace the main connecting rod 7 fixedly connected with the annular bracket 6, and play a role of one-way rotation guiding, and the advantage is that the stroke lengths of each piston are consistent.

The steam valve is an important part of the engine cylinder gas distribution device 11, but the steam valves in the existing engines are generally bell-shaped hard seals. It is not good for increasing the engine speed. Another improvement of the utility model is to change the horn-type steam valve used throughout the existing gas distribution device 11 into a plunger-type valve shown in Figure 5, which consists of a piston 13, an air inlet 14, an air outlet 15, a rocker Arm 16, rocker shaft 17 and general-purpose cam type valve tappet 18 etc., the advantage of such improvement is to make sealing softer to be beneficial to adapt to engine speed and improve.

The gas distribution process in the above embodiment is similar to the gas distribution process of the prior art tandem engine and the tandem V-type engine. Generally, those skilled in the art should be able to analogize it, and only need to make an adaptive adjustment according to the specific structure That is, in addition, around the piston on the cylinder body is provided with a cooling water jacket 19 as a general engine.
