Description

Technical Field

[0001] This application relates to the field of transportation facilities, and more specifically, to an integrated gear shaft. Background Technology

[0002] The gear train, gear housing, and gear housing cover are important components of the engine. The gears inside the gear housing mainly include the crankshaft timing main drive gear, the fuel injection pump idler gear, the fuel injection pump timing gear, the camshaft timing gear, the oil pump drive gear, and the hydraulic pump idler gear. Since the gear shafts require oil lubrication, lubrication channels must be provided.

[0003] Currently, the installation of gears and gear chamber covers on engines requires a large number of specialized parts. To ensure lubrication after gear installation, many specialized parts need to be designed, which undoubtedly increases the cost of the engine. Summary of the Invention

[0004] To overcome the shortcomings of the existing system, this application provides an integrated gear shaft that solves the problem that when installing gears and gear chamber covers on an engine, a large number of special parts are required for installation. In order to ensure lubrication after gear installation, many special parts need to be designed, which undoubtedly increases the cost of the engine.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] An integrated gear shaft includes a connecting component and a fixing component.

[0007] The connecting assembly includes a gear shaft and a gear plate. The gear shaft has a lubricating oil hole and is fixedly connected to the gear plate. A mounting hole is provided on one side of the gear shaft, and an oil guide hole is provided through the mounting hole. An oil storage groove is provided at the outer end of the oil guide hole.

[0009] In one specific implementation, a thrust surface is provided on one side of the gear shaft, and the transmission gear abuts against the thrust surface.

[0010] In the above implementation process, a thrust surface is set to limit the position of the transmission gear and bearing, ensuring accurate and stable positioning.

[0011] In one specific implementation, a fixing surface is provided on one side of the gear shaft, and the gear pressure plate abuts against the fixing surface.

[0012] In the above implementation process, a fixed surface is set to limit the installation position of the gear pressure plate and prevent the gear pressure plate from being over-pressed.

[0014] In the above implementation process, by setting an external threaded pipe, an open pipe and a hexagonal head, and the outer diameter of the open pipe is smaller than that of the external threaded pipe, it is beneficial to ensure that the oil can flow smoothly out of the radial hole on the open pipe after entering from the external threaded pipe, and to avoid the outer wall of the open pipe being too close to the inner wall of the mounting hole.

[0015] In one specific implementation, a mounting flange is provided on the circumferential side of the gear shaft, and a reserved hole is provided on the gear plate, the reserved hole being aligned with the mounting flange.

[0016] In the above implementation process, a mounting flange and a reserved hole are provided for bolts to be tightened through the mounting flange and the reserved hole for connection and fixation.

[0017] In one specific implementation, the gear plate has an opening through which one side of the gear shaft passes.

[0018] In one specific implementation, a plurality of fixing bolt holes are provided on the outer side of the gear shaft.

[0019] In the above implementation process, fixing bolt holes are set for mounting the wheel system bracket at these locations, or reserved for vehicle manufacturers to install related vehicle components.

[0020] In one specific implementation, the lubricating oil hole, the mounting hole, the oil passage bolt, the oil guide hole, and the oil reservoir are interconnected.

[0021] In the above process, the connected lubricating oil channels ensure that lubricant is delivered smoothly to the interior for lubrication.

[0022] The advantages of this embodiment are: by setting up a gear shaft, lubricating oil hole, mounting hole, oil guide hole, oil reservoir, gear plate, transmission gear, gear pressure plate and oil passage bolt, and utilizing the various holes and oil passage bolts integrated on the gear shaft, the smooth flow of lubricating oil after installation is ensured. At the same time, the transmission gear, gear pressure plate and oil passage bolt serve as mounting bases. The integrated design greatly improves the function of the gear shaft, reduces the design and development of other special parts, and thus reduces the cost of the engine. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0029] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0030] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0031] Please see Figures 1-4 This application provides an integrated gear shaft including a connecting component 100 and a fixing component 200.

[0032] Please see Figure 1 , 2 3. The connecting assembly 100 includes a gear shaft 110 and a gear plate 120. The gear shaft 110 has a lubricating oil hole 111 and is fixedly connected to the gear plate 120. A mounting hole 112 is provided on one side of the gear shaft 110. The mounting hole 112 is connected to an oil guide hole 113. An oil reservoir 114 is provided at the outer end of the oil guide hole 113. The oil reservoir 114 can prevent poor lubrication.

[0033] The gear shaft 110 is provided with a mounting flange 130 around its periphery, and the gear plate 120 is provided with a reserved hole 121. The reserved hole 121 and the mounting flange 130 are aligned. The mounting flange 130 and the reserved hole 121 are provided to cooperate with bolts to be tightened through the mounting flange 130 and the reserved hole 121 for connection and fixation.

[0034] Specifically, the gear plate 120 has an opening 122 through which one side of the gear shaft 110 passes. The gear shaft 110 has a fixing bolt hole 140 on its outer side. Multiple fixing bolt holes 140 are arranged. The fixing bolt holes 140 are used to install the bracket of the wheel system or to reserve space for the vehicle manufacturer to install related parts of the vehicle.

[0035] Please see Figure 1 , 2 3 and 4, the fixing component 200 includes a transmission gear 210, a gear pressure plate 220 and an oil-passing bolt 230. The transmission gear 210 is sleeved on one side of the gear shaft 110, the oil-passing bolt 230 is threaded to the mounting hole 112, the gear pressure plate 220 is disposed between the transmission gear 210 and the oil-passing bolt 230, and the oil-passing bolt 230 slides through the gear pressure plate 220.

[0036] Among them, a thrust surface 115 is provided on one side of the gear shaft 110, and the transmission gear 210 abuts against the thrust surface 115. By providing the thrust surface 115, the position of the transmission gear 210 and the bearing bush is restricted, so as to ensure accurate and stable positioning.

[0037] Specifically, a fixing surface 116 is provided on one side of the gear shaft 110, and the gear pressure plate 220 abuts against the fixing surface 116. By providing the fixing surface 116, the installation position of the gear pressure plate 220 is restricted, so as to avoid the gear pressure plate 220 being over-pressed.

[0038] In this embodiment, the oil-passing bolt 230 includes an externally threaded tube 231, a perforated tube 232, and a hexagonal head 233. The externally threaded tube 231, the perforated tube 232, and the hexagonal head 233 are integrally formed, and the outer diameter of the perforated tube 232 is smaller than that of the externally threaded tube 231. By setting the externally threaded tube 231, the perforated tube 232, and the hexagonal head 233, and the outer diameter of the perforated tube 232 being smaller than that of the externally threaded tube 231, it is beneficial to ensure that after the oil enters from the externally threaded tube 231, it can flow smoothly out from the radial hole on the perforated tube 232, and avoid the outer wall of the perforated tube 232 being too close to the inner wall of the mounting hole 112.

[0039] In one specific implementation, the lubricating oil hole 111, mounting hole 112, oil passage bolt 230, oil guide hole 113 and oil reservoir 114 are interconnected, and the interconnected lubricating oil channels ensure that lubricant is smoothly delivered to the interior for lubrication.

[0040] The working principle of this integrated gear shaft is as follows: In use, the mounting flange 130 on the gear shaft 110 is first aligned with the reserved hole 121 on the gear plate 120, and then bolts are tightened through to connect. At the same time, the transmission gear 210 is fitted onto the gear shaft 110 through the opening 122 on one side of the gear shaft 110. The oil passage bolt 230 passes through the gear pressure plate 220, and then the oil passage bolt 230 is rotated and screwed into the mounting hole 112. After tightening, the lubricating oil hole 111, mounting hole 112, oil passage bolt 230, oil guide hole 113 and oil reservoir 114 are connected in sequence, so that the lubricating oil can smoothly enter the oil reservoir 114 and the gear chamber for lubrication. The integrated design greatly improves the function of the gear shaft 110, reduces the design and development of other special parts, and thus reduces the cost of the engine.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
