Description

Technical Field

[0001] This utility model relates to the field of gear transmission technology, and more specifically, to a silent straight bevel gear transmission assembly. Background Technology

[0002] Bevel gears, also known as conical gears, are used for transmission between intersecting shafts. Compared to cylindrical gears, they can change the direction of transmission.

[0003] Traditional bevel gears can experience misalignment and loosening between meshing teeth during transmission. This affects transmission and causes noise due to collisions when re-engaging. Furthermore, it makes it difficult to buffer and dampen the gear transmission components, and the vibration makes the gears more prone to loosening, thus affecting their service life. Utility Model Content

[0004] The purpose of this invention is to provide a silent straight bevel gear transmission assembly to solve the problems of misalignment and loosening between meshing teeth, as well as the inconvenience of buffering and damping the gear transmission assembly.

[0005] To achieve the above objectives, a silent straight bevel gear transmission assembly is provided, comprising a base, with grooves on both sides of the top surface of the base, a fixing rod fixedly disposed inside the grooves, a buffer mechanism slidably disposed on both sides of the surface of the fixing rod, a buffer rod rotatably disposed on the top of the buffer mechanism, a mounting block rotatably disposed on the top of the buffer rod, a support plate fixedly disposed on the top surface of the mounting block, a limit gear mechanism rotatably disposed on the top surface of the support plate, a connecting rod fixedly disposed on one side of the top surface of the limit gear mechanism, a straight bevel gear fixedly disposed on the top of the connecting rod, a limit mechanism rotatably disposed on the other side of the top surface of the limit gear mechanism, a drive shaft rotatably disposed inside the limit mechanism, a transmission bevel gear fixedly disposed at one end of the drive shaft, and a damping hydraulic rod fixedly disposed in the middle of the top surface of the base.

[0006] As a further improvement to this technical solution, the buffer mechanism includes sliding blocks slidably disposed on both sides of the surface of the fixed rod, and a buffer spring is fixedly disposed on one side of the sliding block, the buffer spring being used to buffer the sliding block.

[0007] As a further improvement to this technical solution, the end of the buffer spring away from the sliding block is fixedly connected to the groove, and the sliding block is slidably disposed inside the groove, which facilitates the sliding of the sliding block.

[0008] As a further improvement to this technical solution, the limiting gear mechanism includes a left gear rotatably disposed on the top surface of the support plate, a right gear meshing with one side edge of the left gear, and the bottom surface of the right gear rotatably connected to the support plate, the support plate being used to support the limiting gear mechanism.

[0009] As a further improvement to this technical solution, the limiting mechanism includes a limiting rod rotatably disposed on the top surface of the right gear, and a limiting collar is fixedly disposed on the top of the limiting rod, the limiting collar being used to limit the power shaft.

[0010] As a further improvement to this technical solution, a drive shaft is fixedly provided on the top surface of the straight bevel gear, and the drive bevel gear meshes with the straight bevel gear, with the drive shaft used for transmission.

[0011] As a further improvement to this technical solution, the top surface of the base is provided with a rectangular array of fixing screw holes around its perimeter. The internal threads of the fixing screw holes are threaded through the fixing screws, which are used to fix the base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this silent straight bevel gear transmission assembly, through the setting of the limiting gear mechanism and the limiting mechanism, when the transmission bevel gear drives the straight bevel gear to rotate, the left and right gears at the bottom rotate accordingly. The left and right gears mesh and rotate, which can limit the lateral movement of the straight bevel gear and the transmission bevel gear. The limiting rod and the limiting collar limit the longitudinal movement of the power shaft and the transmission bevel gear, so that the straight bevel gear and the transmission bevel gear can fit tightly together and avoid displacement and separation.

[0014] 2. In this silent straight bevel gear transmission assembly, through the setting of buffer mechanism and damping hydraulic rod, when the gear is subjected to vibration during operation, the support plate vibrates, which drives the buffer rod to rotate, so that the sliding block squeezes the buffer spring to absorb the vibration force. At this time, the damping hydraulic rod extends and retracts accordingly, consuming the stored energy of the buffer spring, thus achieving the effect of buffering and shock absorption of the gear and reducing transmission noise.

[0024] Please see Figures 1-5 As shown, the purpose of this embodiment is to provide a silent straight bevel gear transmission assembly, including a base 1. Grooves are provided on both sides of the top surface of the base 1. A fixing rod 2 is fixedly installed inside the groove. A buffer mechanism 3 is slidably installed on both sides of the surface of the fixing rod 2. With the buffer mechanism 3 and the damping hydraulic rod 14, when the gear is subjected to vibration during operation, the support plate 6 vibrates, which drives the buffer rod 4 to rotate. This causes the sliding block 301 to compress the buffer spring 302 to absorb the vibration force. At this time, the damping hydraulic rod 14 extends and retracts accordingly, consuming the energy stored in the buffer spring 302, thereby achieving the effect of buffering and shock absorption of the gear and reducing the noise of the transmission.

[0025] A buffer rod 4 is rotatably mounted on the top of the buffer mechanism 3. A mounting block 5 is rotatably mounted on the top of the buffer rod 4. A support plate 6 is fixedly mounted on the top surface of the mounting block 5. A limit gear mechanism 7 is rotatably mounted on the top surface of the support plate 6. A connecting rod 8 is fixedly mounted on one side of the top surface of the limit gear mechanism 7. A straight bevel gear 9 is fixedly mounted on the top of the connecting rod 8. A limit mechanism 10 is rotatably mounted on the other side of the top surface of the limit gear mechanism 7. Through the setting of the limit gear mechanism 7 and the limit mechanism 10, when the transmission bevel gear 12 drives the straight bevel gear 9 to rotate, the left gear 701 and the right gear 701 at the bottom... Gear 702 rotates as the gear rotates, and left gear 701 and right gear 702 mesh and rotate, which can limit the lateral movement of straight bevel gear 9 and transmission bevel gear 12. Meanwhile, limit rod 1001 and limit collar 1002 limit the longitudinal movement of power shaft 11 and transmission bevel gear 12, so that straight bevel gear 9 and transmission bevel gear 12 can fit tightly together and avoid displacement or separation. The limit mechanism 10 has a rotating power shaft 11 inside, and a transmission bevel gear 12 is fixedly installed at one end of the power shaft 11. A damping hydraulic rod 14 is fixedly installed in the middle of the top surface of the base 1.

[0026] Please see Figure 3 The buffer mechanism 3 includes a sliding block 301 that is slidably disposed on both sides of the surface of the fixed rod 2, and a buffer spring 302 is fixedly disposed on one side of the sliding block 301.

[0027] The buffer mechanism 3 serves to buffer and dampen the gears.

[0028] Please see Figure 2 The end of the buffer spring 302 away from the sliding block 301 is fixedly connected to the groove, and the sliding block 301 is slidably disposed inside the groove.

[0029] The groove is designed to facilitate the sliding of the sliding block 301.

[0030] Please see Figure 4 The limiting gear mechanism 7 includes a left gear 701 rotatably disposed on the top surface of the support plate 6, a right gear 702 meshing with one side edge of the left gear 701, and the bottom surface of the right gear 702 rotatably connected to the support plate 6.

[0031] The limiting gear mechanism 7 serves to limit the movement of the straight bevel gear 9 and the transmission bevel gear 12.

[0032] Please see Figure 4 The limiting mechanism 10 includes a limiting rod 1001 rotatably disposed on the top surface of the right gear 702, and a limiting collar 1002 is fixedly disposed on the top of the limiting rod 1001.

[0033] The limiting mechanism 10 serves to limit the movement of the power shaft 11 and the transmission bevel gear 12.

[0034] Please see Figure 5 A drive shaft 13 is fixedly installed on the top surface of the straight bevel gear 9, and the drive bevel gear 12 meshes with the straight bevel gear 9.

[0035] The drive shaft 13 serves to transmit power.

[0036] Please see Figure 2 The base 1 has a rectangular array of fixing screw holes around its top surface, and fixing screws are inserted through the internal threads of the fixing screw holes.

[0037] The fixing screws serve to fix the base 1.

[0038] Working steps: When the transmission bevel gear 12 drives the straight bevel gear 9 to rotate, the left gear 701 and right gear 702 at the bottom rotate accordingly. The left gear 701 and right gear 702 mesh and rotate, which can limit the lateral movement of the straight bevel gear 9 and the transmission bevel gear 12.

[0039] The limiting rod 1001 and the limiting collar 1002 limit the longitudinal movement of the power shaft 11 and the transmission bevel gear 12, so that the straight bevel gear 9 and the transmission bevel gear 12 can fit tightly together and avoid displacement or separation.

[0040] When the gear is subjected to vibration, the support plate 6 vibrates, causing the buffer rod 4 to rotate. This causes the sliding block 301 to compress the buffer spring 302 and absorb the vibration force. At this time, the damping hydraulic rod 14 extends and retracts accordingly, consuming the stored energy of the buffer spring 302, thus buffering and damping the gear and reducing transmission noise.
