Description

Technical Field

[0001] The utility model relates to the technical field of vehicle mechanical technology, in particular to a lubrication structure of a motorcycle camshaft. Background Art

[0002] The motorcycle camshaft is the core component of the valve train, responsible for controlling the opening and closing of the valves. The camshaft plays a vital role in the four-stroke engine, opening and closing the intake and exhaust valves of the cylinder by rotating. Depending on the design requirements, the configuration of the camshaft is also different. It is usually forged from high-quality carbon steel or alloy steel, and may also be cast using alloy cast iron or ductile iron. In order to improve durability and reduce wear, the journal and working surface of the camshaft will be heat treated and polished.

[0003] The design and selection of the camshaft depends on the specific application and performance requirements of the engine. In the field of motorcycles, both single and dual camshafts have their specific application scenarios and advantages and disadvantages. If the motorcycle camshaft is worn, it may cause inaccurate valve opening, abnormal valve working sound, difficulty in accelerating and reduced power performance. This is because the worn camshaft cannot effectively control the full opening and closing of the valve, resulting in insufficient inflation and incomplete exhaust gas emissions. Therefore, the lubrication effect of the camshaft needs to be considered during the use of the camshaft. While ensuring the smooth opening and closing of the camshaft valve, the wear of the camshaft is minimized. Therefore, a lubrication structure for a motorcycle camshaft is proposed. During the rotation of the camshaft, an oil pipe is connected to supply oil for lubrication, which reduces the possibility of camshaft wear and increases the service life of the camshaft. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a lubrication structure for a motorcycle camshaft, which has the advantages of good practicality and high reliability, and solves the problem that the camshaft may be worn due to insufficient lubrication during operation and cannot effectively control the full opening and closing of the valve.

[0005] In order to achieve the above-mentioned purpose of good practicality and high reliability, the utility model provides the following technical solutions: a lubrication structure for a motorcycle camshaft, comprising a driving gear, a connecting shaft arranged on the top of the driving gear, a lubrication assembly arranged on the outside of the connecting shaft, and an axle assembly arranged on the outside of the connecting shaft; the lubrication assembly comprises an oil delivery pipe groove opened inside the connecting shaft, a plurality of guide holes opened on the side of the connecting shaft, and a spiral groove opened on the side of the connecting shaft.

[0006] Furthermore, the wheel axle assembly includes a first bearing fixedly mounted on the outside of the connecting shaft, a plurality of camshafts arranged on the outside of the connecting shaft, a positioning shaft fixedly mounted on the outside of the connecting shaft, and a second bearing fixedly mounted on the top of the side of the connecting shaft.

[0007] Furthermore, a through hole is provided inside the driving gear, a fixing seat is fixedly installed inside the through hole, and the bottom of the connecting shaft is embedded in the fixing seat and fixedly installed with the fixing seat.

[0008] Furthermore, the oil delivery pipe groove vertically penetrates the connecting shaft and the fixing seat and reaches the top of the connecting shaft and the bottom of the fixing seat respectively.

[0009] Furthermore, the guide hole transversely penetrates both sides of the connecting shaft and the inner center thereof is communicated with the interior of the oil delivery pipe groove.

[0010] Furthermore, the spiral groove is spirally arranged on the entire side surface of the connecting shaft to the upper and lower ends of the side surface of the connecting shaft, and the edge of the spiral groove is arc-shaped and smoothly transitions to the surface of the connecting shaft.

[0011] Furthermore, the spiral groove forms a hole groove on the side of the connecting shaft respectively with the inner side wall of the first bearing, the camshaft, the positioning shaft and the second bearing.

[0012] Furthermore, the inner side wall of the camshaft and the connecting shaft are fixedly installed, and the protruding parts of the two camshafts form an angle.

[0013] Compared with the prior art, the utility model provides a lubrication structure for a motorcycle camshaft, which has the following beneficial effects:

[0014] 1. The lubrication structure of the motorcycle camshaft is characterized in that the first bearing and the second bearing are used to position the overall structure, and then a driving gear is added to the driving device to drive the structure. The rotation of the driving gear drives the fixing seat and the connecting shaft to rotate inside the first bearing and the second bearing. The rotation of the connecting shaft drives the camshaft block to rotate. The rotation of the camshaft block opens and closes the valve, so that the engine can be smoothly inflated and deflated.

[0015] 2. The lubrication structure of the motorcycle camshaft is achieved by filling the oil delivery pipe groove with lubricating oil and the like, and connecting the guide hole and the oil delivery pipe groove inside the connecting shaft. In this way, the connecting shaft will continuously sprinkle the lubricating oil and other materials inside the guide hole on various positions on the surface of the connecting shaft during high-speed rotation, so that the lubricating oil can smoothly enter the camshaft structure after sealing. During the rotation, the spiral grooves on the surface of the connecting shaft will continuously guide the lubricating oil remaining on the surface of the connecting shaft to both ends, so that it will spread on the surface of the connecting shaft, thereby adding oil to the inside of the camshaft. The purpose of lubrication is achieved by adding oil, which solves the problem that the camshaft may be worn due to insufficient lubrication during operation and cannot effectively control the full opening and closing of the valve.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a lubrication structure of a motorcycle camshaft includes a driving gear 1, a connecting shaft 2 arranged on the top of the driving gear 1, a lubrication component 3 arranged on the outside of the connecting shaft 2, and an axle component 4 arranged on the outside of the connecting shaft 2; the lubrication component 3 includes an oil delivery pipe groove 31 opened inside the connecting shaft 2, a plurality of guide holes 32 opened on the side of the connecting shaft 2, and a spiral groove 33 opened on the side of the connecting shaft 2.

[0022] The driving gear 1 is added to the driving device to drive the structure, thereby driving the rotation of the connecting shaft 2. The rotation of the connecting shaft 2 drives the wheel axle assembly 4 to rotate, thereby realizing the opening and closing of the driving valve. The lubrication assembly 3 is connected to the external oil delivery component to lubricate the internal oil supply of the device.

[0023] In this embodiment, the axle assembly 4 includes a first bearing 41 fixedly mounted on the outside of the connecting shaft 2, a plurality of camshaft blocks 42 arranged on the outside of the connecting shaft 2, a positioning shaft 43 fixedly mounted on the outside of the connecting shaft 2, and a second bearing 44 fixedly mounted on the top of the side of the connecting shaft 2.

[0024] The overall structure is positioned by being arranged on the first bearing 41 and the second bearing 44 , and the camshaft block 42 drives the opening and closing of the valve when the connecting shaft 2 rotates.

[0025] In this embodiment, a through hole is opened inside the driving gear 1 , a fixing seat 11 is fixedly installed inside the through hole, and the bottom of the connecting shaft 2 is embedded in the fixing seat 11 and fixedly installed with the fixing seat 11 .

[0026] The fixing seat 11 is arranged inside the driving gear 1 to facilitate the disassembly, cleaning and maintenance of the connecting shaft 2 at a later time.

[0027] In this embodiment, the oil delivery pipe groove 31 vertically penetrates the connecting shaft 2 and the fixing seat 11 and reaches the top of the connecting shaft 2 and the bottom of the fixing seat 11 respectively.

[0028] By filling the oil delivery groove 31 with lubricating oil or the like, the lubricating oil is introduced into the sealed camshaft structure.

[0029] In this embodiment, the guide hole 32 transversely penetrates both sides of the connecting shaft 2 and the inner center thereof is communicated with the interior of the oil delivery pipe groove 31 .

[0030] The guide hole 32 is connected to the oil pipe groove 31 inside the connecting shaft 2 , so that the connecting shaft 2 can continuously sprinkle the lubricating oil and other materials inside the guide hole 32 to various positions on the surface of the connecting shaft 2 during high-speed rotation.

[0031] In this embodiment, the spiral groove 33 is spirally arranged on the entire side surface of the connecting shaft 2 to the upper and lower ends of the side surface of the connecting shaft 2 , and the edge of the spiral groove 33 is arc-shaped and smoothly transitions to the surface of the connecting shaft 2 .

[0032] By providing the spiral groove 33 on the surface of the connecting shaft 2 , the lubricating oil remaining on the surface of the connecting shaft 2 will be continuously directed to both ends, thereby spreading on the surface of the connecting shaft 2 .

[0033] In this embodiment, the spiral groove 33 forms a hole groove with the inner side wall of the first bearing 41, the camshaft block 42, the locking shaft 43 and the second bearing 44 on the side of the connecting shaft 2 respectively.

[0034] The spiral groove 33 forms an arc groove on the surface of the connecting shaft 2 and a hole groove at the same time, so that the lubricating oil attached to the surface of the connecting shaft 2 can flow on the surface.

[0035] In this embodiment, the inner side wall of the camshaft block 42 and the connecting shaft 2 are fixedly installed, and the protruding parts of the two camshaft blocks 42 form an angle.

[0036] By providing different numbers of camshaft blocks 42 , different camshaft blocks 42 form different angles, thereby forming different camshafts.

[0037] The working principle of the above embodiment is:

[0038] The first bearing 41 and the second bearing 44 are used to position and place the entire structure, and then the driving gear 1 is added to the driving device to drive the structure. The rotation of the driving gear 1 drives the fixed seat 11 and the connecting shaft 2 to rotate inside the first bearing 41 and the second bearing 44. The rotation of the connecting shaft 2 drives the camshaft block 42 to rotate. The rotation of the camshaft block 42 opens and closes the valve, allowing smooth inflation and deflation in the engine.

[0039] In addition, by filling the oil delivery pipe groove 31 with lubricating oil, the guide hole 32 and the oil delivery pipe groove 31 inside the connecting shaft 2 are connected, so that the connecting shaft 2 will continuously sprinkle the lubricating oil and other materials inside the guide hole 32 on various positions on the surface of the connecting shaft 2 during high-speed rotation, so that the lubricating oil can smoothly enter the camshaft structure after sealing. During the rotation, the spiral groove 33 on the surface of the connecting shaft 2 will continuously guide the lubricating oil remaining on the surface of the connecting shaft 2 to both ends, thereby expanding on the surface of the connecting shaft 2, thereby adding oil to the inside of the camshaft. The purpose of lubrication is achieved by adding oil, which solves the problem that the camshaft may be worn due to insufficient lubrication during operation and cannot effectively control the full opening and closing of the valve.
