Description

Technical Field

[0001] The present invention belongs to the field of engine rotors, and particularly relates to a support structure for a rotary engine. Background Art

[0002] A rotary engine is a type of engine, and a triangular rotor is connected to its engine shaft. Since the triangular rotor and the output shaft of the engine are eccentrically arranged, vibrations will be generated during operation, which will have a certain negative impact on the working life of the engine. Therefore, we urgently need a support structure for a rotary engine to solve the above problems. Summary of the Invention

[0003] In view of this, the present invention aims to provide a support structure for a rotary engine to solve the problem of vibrations generated during the operation of the engine, which shortens the working life of the engine.

[0004] To achieve the above object, the technical solution of the present invention is realized as follows:

[0005] A support structure for a rotary engine includes a fixing rod, a rubber ring, a bearing bush, and a fixing plate. One end of the fixing rod is fixedly connected to the engine body, and the other end is detachably connected to the fixing plate. A bearing bush is fixedly installed in the middle of the fixing plate. The bearing bush is slidably sleeved on the output shaft of the engine body, and the output shaft and the fixing plate are limitedly connected; a rubber ring is sleeved outside the fixing rod, and a fixing hole is provided on the fixing plate. The rubber ring is embedded and fixed in the fixing hole to form a flexible connection.

[0006] Further, the number of the fixing rods is three, and the three fixing rods are evenly arranged around the side surface of the output shaft.

[0007] Further, an annular bracket is installed on one side of the fixing plate. The annular bracket is threadedly connected with a locking screw, and an outer ring is installed below the locking screw. By rotating the locking screw, the locking screw drives the outer ring to rotate. A groove is provided on the output shaft, and the groove is used for clamping a ball, and the position of the ball is opposite to that of the outer ring. When the locking screw drives the outer ring to rotate, the outer ring clamps the ball into the groove to prevent the fixing plate from sliding in the axial direction of the output shaft.

[0008] Further, the head of the fixing rod is threadedly connected with a fixing nut, and the surfaces of the fixing nut and the fixing plate are in close contact.

[0009] Further, the head of the fixing rod is embedded with a connecting head, and the rubber ring is slidably sleeved outside the connecting head. The rubber ring is used for inserting into the fixing hole.

[0010] Compared with the prior art, the support structure for a rotary engine according to the present invention has the following advantages:

[0011] (1) The rotor engine support structure described in the present invention supports the rotation of the output shaft through the setting of the bearing bush, fixes the fixing plate through the setting of the fixing rod, plays a role in buffering and vibration reduction by setting a rubber ring between the fixing holes of the fixing rod and the fixing plate, and after installing the fixing plate through the setting of the balls, slides the outer ring to make the balls snap into the groove to prevent the fixing plate from sliding in the axial direction of the output shaft, playing a role in limiting the position.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0021] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0022] A rotor engine support structure, as Figures 1 to 3 shown, includes a fixed rod 3, a rubber ring 4, a connector 6, a bearing shell 7, a fixing plate 8, a fixing nut 9, a locking screw 10, an outer ring 11, a ball 12, a groove 13, and an annular bracket 14. One end of the fixed rod 3 is fixedly connected to the engine body 1, and the other end is detachably connected to the fixing plate 8. A bearing shell 7 is fixedly installed in the middle of the fixing plate 8. The bearing shell 7 is slidably sleeved on the output shaft 2 of the engine body 1, and the output shaft 2 and the fixing plate 8 are limitedly connected; a rubber ring 4 is sleeved outside the fixed rod 3, and a fixing hole 5 is provided on the fixing plate 8. The rubber ring 4 is embedded and fixed in the fixing hole 5 to form a flexible connection.

[0023] In the present invention, through the arrangement of the bearing shell 7, the rotation of the output shaft 2 is supported. Through the arrangement of the fixed rod 3, the fixing plate 8 is fixed. By arranging the rubber ring 4 between the fixed rod 3 and the fixing hole 5, a buffering and vibration damping effect is achieved.

[0024] In one or more embodiments, the number of the fixed rods 3 is three, and the three fixed rods 3 are evenly arranged around the side surface of the output shaft 2.

[0025] In one or more embodiments, an annular bracket 14 is mounted on one side of a fixing plate 8. The annular bracket 14 is threadedly connected with a locking screw 10. An outer ring 11 is mounted below the locking screw 10. By rotating the locking screw 10, the locking screw 10 drives the outer ring 11 to rotate. A groove 13 is provided on the output shaft 2, and a ball 12 is adapted to be snapped into the groove 13, and the position of the ball 12 is opposite to that of the outer ring 11. When the locking screw 10 drives the outer ring 11 to rotate, the outer ring 11 snaps the ball into the groove 13, preventing the fixing plate 8 from sliding in the axial direction of the output shaft 2, thus playing a role in limiting.

[0026] The head of the fixing rod 3 is threadedly connected with a fixing nut 9, and the surfaces of the fixing nut 9 and the fixing plate 8 are in close contact.

[0027] The head of the fixing rod 3 is embedded with a connector 6. A rubber ring 4 is slidably sleeved outside the connector 6. The diameter of the rubber ring 4 is the same as the inner diameter of the fixing hole 5. When installing the fixing plate 8, first put the rubber ring 4 on the connector 6 at the head of the fixing rod 3, and then insert the rubber ring 4 together with the connector 6 into the fixing hole 5, so that the rubber ring 4 is connected between the fixing plate 8 and the fixing rod 3, realizing a flexible connection.

[0028] The working principle of a rotor engine support structure is as follows:

[0029] In the present invention, through the provision of the bearing shell 7, the rotation of the output shaft 2 is supported; through the provision of the fixing rod 3, the fixing plate 8 is fixed; by providing a rubber ring 4 between the fixing hole 5 of the fixing rod 3 and the fixing plate 8, a buffering and vibration damping effect is achieved; through the provision of the ball 12, after the fixing plate 8 is installed, the outer ring 11 is slid so that the ball 12 is snapped into the groove 13, preventing the fixing plate 8 from sliding in the axial direction of the output shaft 2, thus playing a role in limiting.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
