Description
Technical Field
[0001] The utility model relates to the technical field of transmission shafts, in particular to a transmission shaft hanger with good shock absorbing effect. Background Art
[0002] The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial. Generally, the drive shaft must undergo a dynamic balance test and be adjusted on a balancing machine before leaving the factory. For front-engine, rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can be composed of several sections, and the sections can be connected by universal joints.
[0003] For example, the utility model with announcement number CN214450286U discloses a transmission shaft hanger with good shock-absorbing effect, including a hanger, a bearing seat and a bearing. A shock-absorbing mechanism is arranged between the inner wall of the hanger and the outer wall of the bearing seat. The shock-absorbing mechanism is composed of a first shock-absorbing layer, a second shock-absorbing layer and a plurality of shock-absorbing monomers. The shock-absorbing monomers include a shock-absorbing ball and a shock-absorbing column. The shock-absorbing ball is fixed on the first shock-absorbing layer, and the shock-absorbing column is fixed on the second shock-absorbing layer. The shock-absorbing column is provided with an accommodating port for accommodating the shock-absorbing ball. A plurality of first annular shock-absorbing rings are evenly arranged on the outer wall of the shock-absorbing column along its axial direction. A shock-absorbing sleeve is also arranged on the second shock-absorbing layer and is sleeved outside the shock-absorbing column. The shock-absorbing sleeve is consistent with the central axis of the shock-absorbing column. A plurality of second annular shock-absorbing rings are evenly arranged on the inner wall of the shock-absorbing sleeve along its axial direction. The second annular shock-absorbing rings are located between the first annular shock-absorbing rings adjacent to each other on the shock-absorbing column. The structure is novel and reasonable. The shock-absorbing mechanism is compressed and deformed to generate a reaction force that offsets the impact force, thereby achieving a good shock-absorbing effect.
[0004] In the process of implementing this application, it was found that the technology has the following problems: most of the existing drive shaft hangers with good shock absorbing effects achieve good shock absorbing effects by compressing and deforming the shock absorbing mechanism to generate reaction force and offset the impact force, but most shock absorbing mechanisms are attached to the outer surface of the bearing seat during use, which makes it easy for the bearing seat to rub against the outer surface of the shock absorbing mechanism during vibration, which makes the bearing seat and the shock absorbing mechanism easy to be damaged by friction after long-term use, thereby reducing the practicality of the equipment.
[0005] Therefore, a transmission shaft hanger with good shock absorbing effect is proposed. Utility Model Content
[0006] The purpose of the utility model is to solve the problem that most shock-absorbing mechanisms are fitted to the outer surface of the bearing seat during use, which makes the bearing seat easily rub against the outer surface of the shock-absorbing mechanism during vibration, thereby causing the bearing seat and the shock-absorbing mechanism to be easily damaged by friction after long-term use.

[0026] like Figures 1 to 4 As shown, a transmission shaft hanger with good shock-absorbing effect includes a U-shaped fixing frame 1, a transmission shaft 4 and a bearing seat 5. A plurality of support plates 2 are installed on the inner wall of the U-shaped fixing frame 1, and the transmission shaft 4 is installed inside the bearing seat 5. A shock-absorbing mechanism 3 for limiting the moving range of the bearing seat 5 is installed on the side of the plurality of support plates 2 away from the U-shaped fixing frame 1. A card slot is provided on the front and rear sides of the shock-absorbing mechanism 3, and a limiting mechanism 6 is installed inside the card slots on the front and rear sides of the shock-absorbing mechanism 3. A driving mechanism 8 is arranged inside the two sets of limiting mechanisms 6; specifically, the shock-absorbing mechanism 3 is connected to the outer surface of the bearing seat 5 by card slotting, so that the shock-absorbing mechanism 3 moves synchronously during the vibration of the transmission shaft 4, thereby avoiding as much as possible the friction between the outer surface of the bearing seat 5 and the outer surface of the shock-absorbing structure during the vibration of the bearing seat 5 driven by the transmission shaft 4, which may cause damage to the bearing seat 5 or the shock-absorbing structure after long-term use, thereby improving the practicability of the device.
[0027] like Figure 1 and Figure 2 As shown, the shock absorbing mechanism 3 includes a fixed sleeve 301, and the inner wall of the fixed sleeve 301 is provided with five groups of slots, and the inside of the five groups of slots of the fixed sleeve 301 are all slidably connected with sliders 303, and the side of the five groups of sliders 303 away from the fixed sleeve 301 is installed with spring telescopic rods 304, and the ends of the five groups of spring telescopic rods 304 away from the fixed sleeve 301 are all installed with connecting sleeves 302, and the five groups of connecting sleeves 302 are all clamped on the outer end of the bearing seat 5, and the adjacent sides of the five groups of connecting sleeves 302 are in contact with each other;
[0028] Specifically, the five sets of spring telescopic rods 304 are deformed during the vibration of the transmission shaft 4, and a large part of the pressure generated by the transmission shaft 4 is absorbed for contraction deformation, so that the five sets of spring telescopic rods 304 buffer the transmission shaft 4 and the bearing seat 5 during the vibration, and then the five sets of connecting sleeves 302 are clamped on the outer end of the bearing seat 5, so that the five sets of connecting sleeves 302 are moved synchronously during the vibration of the transmission shaft 4, so as to avoid the friction between the outer surface of the bearing seat 5 and the outer surface of the shock-absorbing structure during the vibration of the bearing seat 5 driven by the transmission shaft 4, which may cause damage to the bearing seat 5 or the shock-absorbing structure after long-term use, thereby improving the practicality of the device.
[0029] like Figure 1 and Figure 2 As shown, the two groups of limiting mechanisms 6 include connecting rods 601, and the front and rear sides of the fixed sleeve 301 are provided with card slots. The two groups of connecting rods 601 are respectively connected to the front and rear card slots of the fixed sleeve 301. The two groups of connecting rods 601 are respectively connected to the front and rear card slots of the fixed sleeve 301. The two groups of connecting rods 601 are respectively connected to the opposite sides of the two groups of fixing rings 602. The adjacent sides of the two groups of fixing rings 602 are respectively attached to the opposite sides of the front and rear sliders 303. Specifically, after the five groups of sliders 303 are respectively installed in the five groups of card slots of the fixed sleeve 301, the two groups of connecting rods 601 are connected by moving the two groups of fixing rings 602. 601 are respectively inserted into the front and rear side slots of the fixed sleeve 301, and then by pushing the two groups of fixed rings 602, the adjacent sides of the two groups of fixed rings 602 are respectively attached to the opposite sides of the front and rear groups of sliders 303, so that the two groups of limiting mechanisms 6 can limit the moving position of the five groups of sliders 303 in the five groups of slots of the fixed sleeve 301 during use, so as to avoid the five groups of sliders 303 from moving out of the five groups of slots of the fixed sleeve 301 during the vibration of the transmission shaft 4, thereby improving the stability of the shock absorbing mechanism 3 during use.
[0030] like Figure 2As shown, grooves are provided on the front and rear sides of the fixed sleeve 301, and magnetic blocks 7 are arranged inside the two groups of grooves of the fixed sleeve 301, and the opposite sides of the two groups of magnetic blocks 7 are respectively adsorbed on the adjacent sides of the two groups of fixed rings 602; specifically, when the adjacent sides of the two groups of fixed rings 602 are respectively attached to the front and rear sides of the two groups of fixed sleeves 301, the positions of the two groups of magnetic blocks 7 are respectively arranged on the front and rear sides of the fixed sleeve 301, so that the opposite sides of the two groups of magnetic blocks 7 are respectively adsorbed on the adjacent sides of the two groups of fixed rings 602, and then the two groups of magnetic blocks 7 perform secondary restrictions on the positions of the two groups of fixed rings 602 on the front and rear sides of the fixed sleeve 301, so as to avoid the movement of the two groups of limiting mechanisms 6 during use as much as possible, thereby improving the stability of the limiting mechanism 6 during use.
[0031] like Figure 1 and Figure 2 As shown, a plurality of groups of diamond-shaped material-reducing holes 9 are opened inside the front of the U-shaped fixing frame 1; specifically, by opening a plurality of groups of diamond-shaped material-reducing holes 9 inside the U-shaped fixing frame 1, the mass of the U-shaped fixing frame 1 is reduced, thereby reducing the time and labor consumed by subsequent staff when installing and disassembling the device, thereby improving the practicality of the device.
[0032] like Figure 2 and Figure 3 As shown, the two groups of driving mechanisms 8 both include a fixing rod 802, and a slot is provided on the opposite side of the two groups of fixing rings 602, and a through hole is provided on the top of the inner wall of the slot of the two groups of fixing rings 602, and the two groups of fixing rods 802 are respectively rotatably connected to the two groups of through holes of the fixing rings 602, and the outer surfaces of the two groups of fixing rods 802 are installed with L-shaped handles 801, and the two groups of L-shaped handles 801 are respectively clamped in the slots of the two groups of fixing rings 602; specifically, before the staff disassembles the movable limiting mechanism 6, the staff pushes the L-shaped handle 801 to drive the fixing rod 802 to rotate inside the through hole of the fixing ring 602, so that one end of the L-shaped handle 801 moves out of the slot of the fixing ring 602 during the rotation of the fixing rod 802, and then the fixing ring 602 is moved by pulling the L-shaped handle 801, so that the staff does not need to take tools during the process of disassembling the movable limiting mechanism 6, thereby shortening the time spent by the subsequent staff when disassembling the movable limiting mechanism 6.
[0033] In summary, the five sets of spring telescopic rods 304 are deformed during the vibration of the transmission shaft 4, and a large part of the pressure generated by the transmission shaft 4 is absorbed for shrinkage deformation, so that the five sets of spring telescopic rods 304 buffer the transmission shaft 4 and the bearing seat 5 during the vibration, and then the five sets of connecting sleeves 302 are clamped on the outer end of the bearing seat 5, so that the five sets of connecting sleeves 302 are synchronously moved during the vibration of the transmission shaft 4, so as to avoid the outer surface of the bearing seat 5 and the outer surface of the shock-absorbing structure from rubbing against each other during the vibration of the bearing seat 5 driven by the transmission shaft 4, which may cause the bearing seat 5 or the shock-absorbing structure to vibrate. Damage occurs after long-term use; by moving the two sets of fixed rings 602, the two sets of connecting rods 601 are respectively inserted into the front and rear side grooves of the fixed sleeve 301, and then by pushing the two sets of fixed rings 602, the adjacent sides of the two sets of fixed rings 602 are respectively attached to the opposite sides of the front and rear sets of sliders 303, so that the two sets of limiting mechanisms 6 can limit the moving position of the five sets of sliders 303 in the five sets of slots of the fixed sleeve 301 during use, so as to avoid the five sets of sliders 303 from moving out of the five sets of slots of the fixed sleeve 301 during the vibration of the transmission shaft 4.
[0034] At the same time, by pushing the L-shaped handle 801, the fixing rod 802 is driven to rotate inside the through hole of the fixing ring 602, so that one end of the L-shaped handle 801 moves out of the slot of the fixing ring 602 during the rotation of the fixing rod 802, and then the fixing ring 602 is moved by pulling the L-shaped handle 801, so that the staff does not need to take tools during the process of disassembling the movable limiting mechanism 6, thereby shortening the time spent by subsequent staff in disassembling the movable limiting mechanism 6.
