Description

Technical Field

[0001] The present invention relates to the field of transmission structures, and in particular to a transmission component and a transmission device. Background Art

[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. At present, the conversion of linear motion to circular motion is mainly achieved through the crankshaft. However, when the piston pushes the crankshaft connecting rod to reciprocate in the cylinder, the lateral force acts on the cylinder wall, and the high-frequency left and right shaking makes it difficult to seal and causes serious eccentric wear.

[0003] In the prior art, when the crankshaft connecting rod is pushed by the piston to reciprocate in the cylinder, the lateral force acts on the cylinder wall, and the eccentric wear causes the piston to be damaged and the sealing is low; therefore, it is necessary to improve the prior art and propose a more reasonable technical solution to solve the problems existing in the prior art. Summary of the invention

[0004] The invention provides a transmission component and a transmission device, which are used to solve the technical problems in the prior art that when the piston pushes the crankshaft connecting rod to reciprocate in the cylinder, the lateral force acts on the cylinder wall, the eccentric wear causes the piston to be damaged, and the sealing is low.

[0005] In a first aspect, an embodiment of the present invention provides a transmission component, comprising: a limit assembly, an input gear, a transmission assembly and an output assembly; wherein:

[0006] The limiting assembly is provided with a limiting groove, in which an input bearing and an inner gear ring are arranged;

[0007] The transmission assembly includes a transmission shaft, an eccentric disk and a transmission gear matched with an inner gear ring. The input gear is provided with an input eccentric hole, and the transmission shaft is arranged in the input eccentric hole. The transmission shaft is connected to the outer periphery of the axis of the eccentric disk, and the distance between the hole center of the input eccentric hole and the axis center of the input gear is equal to the distance between the axis center of the transmission shaft and the axis center of the eccentric disk. The transmission gear is sleeved on the transmission shaft, and the transmission gear meshes with the inner gear ring and has the same modulus, and the number of teeth of the inner gear ring is twice the number of teeth of the transmission gear. Under the action of the transmission shaft, the transmission gear revolves around a circular orbit at half the radius of the pitch circle of the inner gear ring.

[0008] The output assembly includes an output connecting rod and an output bearing sleeved on the outer periphery of the eccentric disk. The input gear is rotatably connected to the limit assembly through the input bearing. The limit assembly is provided with a limit piece. The output connecting rod is restricted by the limit piece and driven by the transmission assembly to reciprocate along the central axis direction of the output assembly.

[0009] The crankshaft is the most important component in the engine. It mainly converts the force transmitted from the connecting rod into torque to drive other accessories on the engine. At present, the conversion of linear motion to circular motion is mainly achieved through the crankshaft. However, when the piston pushes the crankshaft connecting rod to move back and forth in the cylinder, the force of the piston acts vertically on the connecting rod except for the vertex. At other times, there is an angle, resulting in limited strength of the connecting rod's lateral force structure. The lateral force acts on the cylinder wall, and the high-frequency left and right shaking makes it difficult to seal, causing severe eccentric wear and a short service life. In order to increase the service life of the piston, it is ensured that when the piston pushes the crankshaft connecting rod to move back and forth in the cylinder, the lateral force of the piston on the cylinder wall should be reduced, and the friction between the piston and the piston wall when the piston swings left and right should be reduced or eliminated.

[0010] The limiting assembly provided in the embodiment of the present invention is provided with a limiting groove, and the input bearing arranged in the limiting groove limits the input gear to rotate only by itself, so as to prevent the input gear from deflecting under the action of external force. The input gear is provided with an input eccentric hole, and the transmission shaft is arranged in the input eccentric hole; wherein the transmission shaft is arranged in the input eccentric hole and is rotatably connected with the input gear; for example, the transmission shaft is rotatably arranged in the input eccentric hole through a bearing. At the same time, the transmission shaft is connected to the outer periphery of the axis of the eccentric disk, and the distance between the hole center of the input eccentric hole and the axis center of the input gear is equal to the distance between the axis center of the transmission shaft and the axis center of the eccentric disk. The output assembly includes an output connecting rod and an output bearing sleeved on the outer periphery of the eccentric disk, the output bearing is sleeved on the outer periphery of the eccentric disk, and the eccentric disk is connected to the output connecting rod through the output bearing. When the input gear is driven by external power, the transmission gear, under the action of the transmission shaft, revolves around a circular orbit at half the radius of the inner gear ring pitch circle. The motion trajectory of the transmission gear is exactly the same as that of the transmission shaft. The vertical motion trajectory of the center of the eccentric disk integrally formed with the transmission shaft is the central axis of the output connecting rod. The eccentric disk drives the output bearing and the output connecting rod to move back and forth vertically.

[0011] The input gear is connected to the limit assembly through the input bearing to prevent the input gear from squeezing the limit assembly and reduce friction. That is, the power of the input gear rotation is converted into the power of the output connecting rod moving upward and downward, that is, in the vertical direction.

[0012] By providing an output bearing, the friction between the eccentric disk and the output connecting rod is reduced, thereby improving the adaptation effect of the transmission components and reducing mechanical losses.

[0013] The limit assembly includes a limit groove, in which an inner gear ring and an input bearing are arranged; the transmission assembly includes a transmission shaft, an eccentric disk and a transmission gear matched with the inner gear ring, the transmission shaft is arranged in the input eccentric hole, the transmission gear is sleeved on the transmission shaft, and the transmission gear is meshed with the inner gear ring. In order to ensure the stability of the output assembly when it moves back and forth along the central axis of the output connecting rod through the limit of the limit member, in addition to ensuring the stability of the input gear's rotation, it is also necessary to ensure the stability of the transmission gear's revolution; at the same time, the friction of the output assembly on the limit member can be reduced. By setting the limit groove, the transmission shaft matches the inner gear ring through the transmission bearing, which ensures the stability of the transmission gear's revolution, and then ensures the stability of the eccentric disk.

[0014] Similarly, the output connecting rod is rigidly connected to the piston. When the piston reciprocates in the cylinder, it drives the output connecting rod to reciprocate along the central axis of the output assembly through the limiter. When the output connecting rod reciprocates, the eccentric plate drives the transmission gear to revolve around the axis of the input gear to drive the input gear to rotate. The reciprocating linear motion of the output connecting rod is converted into the rotation of the input gear to drive other accessories. When the piston reciprocates in the cylinder, no lateral force is generated on the cylinder wall, eliminating the friction between the piston and the piston when it swings left and right. This solves the technical problems in the prior art that when the piston pushes the crankshaft connecting rod to reciprocate in the cylinder, the lateral force acts on the cylinder wall, the eccentric wear causes the piston to be damaged, and the sealing is low.

[0015] Preferably, the input gear comprises an outer gear and a first inner sleeve, the first inner sleeve is connected to the outer gear and formed integrally, the first inner sleeve is arranged in the limiting groove through the input bearing, and the outer gear is located outside the limiting assembly.

[0016] In order to ensure the stability of the output assembly when it moves back and forth along the central axis of the output connecting rod under the restriction of the limiter, the stability of the input gear's rotation should be ensured, and the friction of the limiter assembly due to the extrusion of the transmission assembly should be reduced; the first inner sleeve is arranged in the limiter groove through the input bearing; at the same time, an external gear is arranged to facilitate connection with the external power input end or output end.

[0017] Preferably, a gasket is further provided in the limiting groove, and the gasket is provided between the input bearing and the inner gear ring.

[0018] The gasket is provided to prevent the first inner sleeve of the input gear from scraping the inner gear ring and the transmission gear when the input gear rotates.

[0019] Preferably, the limiting member includes limiting holes formed at both ends of the limiting assembly, and the output connecting rod extends outward through the limiting holes.

[0020] The limit member can adopt a variety of structures to limit the vertical reciprocating motion of the output connecting rod; in this embodiment, the limit member is a limit hole opened at both ends of the limit assembly; of course, the limit hole can also be a limit hole opened at one end of the limit assembly, and the output connecting rod extends outward through the limit hole to perform work or is subjected to the reverse action of external force and performs work externally through the input gear.

[0021] Preferably, the limiting assembly comprises a top box, a bottom box and a fixing bolt assembly, the top box and the bottom box are fixed by the fixing bolt assembly and the limiting groove is arranged between the top box and the bottom box.

[0022] By setting up a top box and a bottom box and connecting them through a fixing bolt assembly, it is convenient to inspect and repair the transmission parts. At the same time, the length of the output connecting rod and the number of limit holes can be selected according to needs.

[0023] Preferably, the transmission assembly further comprises a fixing nut, and a mounting head matching the nut is arranged on one side of the transmission shaft close to the input gear, and the mounting head passes through the input eccentric hole and is connected to the fixing nut.

[0024] A fixing nut is provided, and a mounting head matching the fixing nut is provided on the side of the transmission shaft close to the input gear, which can prevent the input gear from falling off under the action of external force and ensure the connection strength between the transmission shaft and the input gear.

[0025] Preferably, the external gear is provided with a nut hole, and the fixing nut is arranged in the nut hole.

[0026] A nut hole is provided on the outer wheel to prevent the fixing nut from protruding outward when connected to the transmission shaft, so as to facilitate external force to act directly on the input gear, which is changed into the output connecting rod running up and down through the transmission component to perform external work.

[0027] Preferably, the transmission component further comprises an auxiliary input wheel, which is mirror-symmetrical to the input gear via an eccentric disk.

[0043] See also Figures 1 to 5 The embodiment of the present invention provides a transmission component 1, comprising: a limit assembly 10, an input gear 11, a transmission assembly 12 and an output assembly 13; wherein,

[0044] The limiting assembly 10 is provided with a limiting groove 101, and an input bearing 14 and an inner gear ring 15 are arranged in the limiting groove 101;

The input gear 11 is provided with an input eccentric hole 111, and the transmission shaft 121 is arranged in the input eccentric hole 111; the transmission shaft 121 is connected to the outer periphery of the axis of the eccentric disk 122, and the distance between the hole center of the input eccentric hole 111 and the axis center of the input gear 11 is equal to the distance between the axis center of the transmission shaft 121 and the axis center of the eccentric disk 122; the transmission gear 123 is sleeved on the transmission shaft 121, the transmission gear 123 is meshed with the inner gear ring 15 and the modulus is equal, and the number of teeth of the inner gear ring 15 is twice the number of teeth of the transmission gear 123; under the action of the transmission shaft 121, the transmission gear 123 revolves around a circular orbit at half the radius of the pitch circle of the inner gear ring 15;

[0046] The output assembly 13 includes an output connecting rod 131 and an output bearing 132 sleeved on the outer periphery of the eccentric disk 122. The input gear 11 is rotatably connected to the limit assembly 10 through the input bearing 14. The limit assembly 10 is provided with a limit member 102. The output connecting rod 131 is restricted by the limit member 102 and driven by the transmission assembly 12 to reciprocate along the central axis direction of the output assembly 13.

[0047] The crankshaft is the most important component in the engine. It mainly converts the force transmitted from the connecting rod into torque to drive other accessories on the engine. At present, the conversion of linear motion to circular motion is mainly achieved through the crankshaft. However, when the piston pushes the crankshaft connecting rod to move back and forth in the cylinder, the force of the piston acts vertically on the connecting rod except for the vertex. At other times, there is an angle, resulting in limited strength of the connecting rod's lateral force structure. The lateral force acts on the cylinder wall, and the high-frequency left and right shaking makes it difficult to seal, causing severe eccentric wear and a short service life. In order to increase the service life of the piston, it is ensured that when the piston pushes the crankshaft connecting rod to move back and forth in the cylinder, the lateral force of the piston on the cylinder wall should be reduced, and the friction between the piston and the piston wall when the piston swings left and right should be reduced or eliminated.

[0048] The limiting assembly 10 provided in the embodiment of the present invention is provided with a limiting groove 101, and the input bearing 14 provided in the limiting groove 101 limits the input gear 11 to rotate only by itself, so as to prevent the input gear 11 from deflecting under the action of external force. The input gear 11 is provided with an input eccentric hole 111, and a transmission shaft 121 is provided in the input eccentric hole 111; wherein the transmission shaft 121 is provided in the input eccentric hole 111 and is rotatably connected with the input gear 11; for example, the transmission shaft 121 is rotatably provided in the input eccentric hole 111 through a bearing. At the same time, the transmission shaft 121 is connected to the outer periphery of the axis of the eccentric disk 122, and the distance between the hole center of the input eccentric hole 111 and the axis center of the input gear 11 is equal to the distance between the axis center of the transmission shaft 121 and the axis center of the eccentric disk 122. The output assembly 13 includes an output connecting rod 131 and an output bearing 132 sleeved on the outer periphery of the eccentric disk 122. The output bearing 132 is sleeved on the outer periphery of the eccentric disk 122, and the eccentric disk 122 is connected to the output connecting rod 131 through the output bearing 132. When the input gear 11 is driven by external power, the transmission gear 123, under the action of the transmission shaft 121, revolves around a circular orbit at half the radius of the pitch circle of the inner gear ring 15, and the motion trajectory of the transmission gear 123 is exactly the same as that of the transmission shaft 121; the eccentric disk 122 integrally formed with the transmission shaft 121 moves vertically to the center of the circle, and the motion trajectory is the central axis of the output connecting rod 131, and the eccentric disk 122 drives the output bearing 132 and the output connecting rod 131 to move vertically back and forth.

[0049] The input gear 11 is connected to the stopper assembly 10 via the input bearing 14 to prevent the input gear 11 from squeezing the stopper assembly 10 and reduce friction, that is, the power of the rotation of the input gear 11 is converted into the power of the output connecting rod 131 moving upward and downward, that is, in the vertical direction.

[0050] By providing the output bearing 132 , the friction between the eccentric disk 122 and the output connecting rod 131 is reduced, thereby improving the adaptation effect of the transmission component 1 and reducing the mechanical loss of the transmission component 1 .

[0051] The limiting assembly 10 includes a limiting groove 101, in which an inner gear ring 15 and an input bearing 14 are arranged; the transmission assembly 12 includes a transmission shaft 121, an eccentric disk 122 and a transmission gear 123 matched with the inner gear ring 15, the transmission shaft 121 is arranged in the input eccentric hole 111, the transmission gear 123 is sleeved on the transmission shaft 121, and the transmission gear 123 is meshed with the inner gear ring 15. In order to ensure the stability of the output assembly 13 when it moves back and forth along the central axis direction of the output connecting rod 131 through the limiting member 102, in addition to ensuring the stability of the rotation of the input gear 11, it is also necessary to ensure the stability of the revolution of the transmission gear 123; at the same time, the friction of the output assembly 13 on the limiting member 102 can be reduced. By setting the limiting groove 101, the transmission shaft 121 matches the inner gear ring 15 through the transmission shaft 121 bearing, which ensures the stability of the revolution of the transmission gear 123, and further ensures the stability of the eccentric disk 122.

[0052] Similarly, the output connecting rod 131 is rigidly connected to the piston. When the piston reciprocates in the cylinder, it drives the output connecting rod 131 to reciprocate along the central axis of the output assembly 13 through the stopper 102. When the output connecting rod 131 reciprocates, it drives the transmission gear 123 to revolve around the axis of the input gear 11 through the eccentric disk 122, so as to drive the input gear 11 to rotate. The reciprocating linear motion of the output connecting rod 131 is converted into the rotation of the input gear 11 to drive other accessories to work. When the piston reciprocates in the cylinder, no lateral force is generated on the cylinder wall, and the friction between the piston and the piston when the piston swings left and right is eliminated. In this way, the technical problems in the prior art that when the piston drives the crankshaft connecting rod to reciprocate in the cylinder, the lateral force acts on the cylinder wall, the eccentric wear causes the piston to be damaged, and the sealing is low are solved.
