Description

Technical Field

[0001] The utility model belongs to the technical field of engines, and in particular relates to a novel camshaft column. Background Art

[0002] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Since the movement of the valves is related to the power and operating characteristics of an engine, the camshaft design plays a very important role in the design of the engine. Traditional camshafts must be replaced after the shaft is damaged due to long-term work. The cost of use is high and cannot meet people's needs. When rotating at high speed, a large amount of heat will be generated, and the gear plate will suffer greater damage. The structural strength is easily reduced due to high temperature. Therefore, how to improve the heat dissipation effect and improve the structural strength is a current problem. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the specific technical scheme of a new type of camshaft column of the utility model is as follows:

[0005] A new type of camshaft column, including a first shaft body, a second shaft body and a circular wheel disc, the right end of the first shaft body is fixedly connected to a T-block, the left end of the second shaft body is fixedly connected to a mounting sleeve, the T-block is connected to the inside of the mounting sleeve, the circular wheel disc is arranged at both ends of the camshaft column, and the upper and lower ends of the mounting sleeve are respectively provided with resistance devices, the resistance device includes a trapezoidal block, a threaded column arranged at the top of the trapezoidal block, a spring sleeved on the outer surface of the threaded column and a screw sleeve device sleeved on the top of the threaded column, the screw sleeve device includes a nut and handles arranged on both sides of the nut.

[0006] Furthermore, the T-shaped block includes a vertical block and a horizontal block, and the horizontal block is vertically connected to the vertical block.

[0007] Furthermore, the length of the vertical block is greater than the distance between the two trapezoidal blocks.

[0008] Furthermore, the circular wheel disc includes a disc body and an axial hole arranged on the disc body and adapted to the shaft body, the disc body is provided with reinforcing ribs, the reinforcing ribs are arranged in a ring shape on the disc body, and a fan-shaped area is formed between adjacent reinforcing ribs, and a plurality of first air holes and second air holes are opened on the fan-shaped area.

[0009] Furthermore, the aperture of the first ventilation hole is larger than the aperture of the second ventilation hole.

[0010] A new type of camshaft column of the utility model has the following advantages:

[0011] 1. Through the setting of T-blocks, trapezoidal blocks, threaded columns, springs, nuts and handles, the processing difficulty is reduced and the assembly and disassembly of the two shafts are convenient. At the same time, when the shaft is damaged, only some parts need to be replaced, reducing maintenance costs.

[0012] 2. The arrangement of the disc body, the shaft hole, the reinforcing ribs, the first vent hole and the second air hole solves the problem of high temperature and heat dissipation when the circular disc rotates at high speed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to better understand the purpose, structure and function of the utility model, a new type of camshaft column of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-3As shown, the utility model patent provides a new type of camshaft column, including a first shaft body 1, a second shaft body 2 and a round wheel disc 4, the right end of the first shaft body 1 is fixedly connected with a T-block 6, the left end of the second shaft body 2 is fixedly connected with a mounting sleeve 3, the T-block 6 is located inside the mounting sleeve 3, the round wheel disc 4 is arranged at both ends of the camshaft column, the upper and lower ends of the mounting sleeve 3 are respectively provided with a resistance device 8, the resistance device 8 includes a trapezoidal block 9, a threaded column 10 arranged at the top of the trapezoidal block 9, a spring 11 sleeved on the outer surface of the threaded column 10 and a screw sleeve device 5 sleeved on the top of the threaded column 10, the threaded column 10 is away from the trapezoidal block 9. One end of the trapezoidal block 9 extends to the outside of the mounting sleeve 3 and is fixedly connected to a screw sleeve device 5. The screw sleeve device 5 includes a nut 12 and handles 13 arranged on both sides of the nut 12 to facilitate the disassembly of the two shafts. One end of the spring 11 is fixedly connected to the top of the trapezoidal block 9, and the other end of the spring 11 is fixedly connected to the threaded column 10. The elastic force of the spring 11 blocks the T-block 6 behind the resistance device 8. The T-block 6 includes a vertical block 7 and a horizontal block 18 fixedly connected to the vertical block 7. The horizontal block 18 is perpendicular to the vertical block 7. The length of the vertical block 7 is greater than the spacing between the two trapezoidal blocks 9.

[0020] When in use, the T-block 6 of the first shaft body 1 is connected to the mounting sleeve 3 of the second shaft body 2. The first shaft body 1 applies thrust to the T-block 6, so that the vertical block 7 squeezes the two trapezoidal blocks 9, causing the spring 11 to be compressed and the threaded column 10 to move upward. Finally, the vertical block 7 is stuck behind the trapezoidal block 9 to achieve the installation connection of the two shaft bodies. When the two shaft bodies need to be separated, just hold the handle 13 and rotate it to make the threaded column 10 move upward and the spring be compressed, and then pull out the first shaft body 1. The whole process is easy to operate.

[0021] like Figure 4 As shown, the circular wheel 4 includes a disk body 19 and an axial hole 15 arranged on the disk body 19 and adapted to the shaft body, a plurality of reinforcing ribs 14 are arranged on the disk body 19 in an annular shape, and the strength of the structure is improved by adopting the above-mentioned structural arrangement; a fan-shaped area is formed between every two adjacent reinforcing ribs 14, and a plurality of first air holes 16 and second air holes 17 are opened on the fan-shaped area, and the aperture of the first air hole 16 is larger than the aperture of the second air hole 17. When the disk body rotates, the first air hole 16 and the second air hole 17 have different apertures, so that different air flow differences are formed around them, thereby improving the fluidity of the air flow and improving the heat dissipation effect.
