Description

Technical Field

[0001] The utility model relates to the technical field of transmission boxes, in particular to a multi-purpose forward and reverse transmission box. Background Art

[0002] The transmission box can realize the functions of acceleration and deceleration, which is why it is called a variable speed gearbox. Through the different combinations of the size and number of gears, the transmission box can increase or decrease the output speed while keeping the input speed unchanged, thus meeting the different speed requirements of various mechanical equipment.

[0003] In existing transmission box designs, such as the utility model with patent number CN216271327U, the friction device at the output end is usually neglected. If the output end is suddenly stuck due to an accident, the internal mechanical parts will be subjected to huge pressure and impact due to the sudden stop. In this case, if there is no appropriate friction device to reduce the impact, these parts may be damaged due to the sudden huge pressure, and may even cause the failure of the entire transmission system. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-purpose forward and reverse transmission box to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-purpose forward and reverse transmission box, comprising a shell, wherein a plurality of telescopic rods arranged in a ring shape are arranged in the shell, a spring is sleeved on the outside of each telescopic rod, a friction plate is fitted with the spring and the end of the telescopic rod away from the shell, the side of the friction plate away from the telescopic rod is fitted with the same friction plate, and the same spring, telescopic rod and shell are arranged on opposite sides of the two friction plates, an oil pipeline arranged in the same ring shape is arranged between the springs, the end of the oil pipeline away from the center of the ring is close to the side of the spring, and the end close to the center of the circle is connected to the side of the connecting box, an oil inlet pipe is connected to the connecting box, the oil inlet pipe passes through an opening provided in the shell, and a refueling port is connected at its end, a buckle is fixed on the side of the shell, a connecting ring is buckled on the outside of the buckle, the connecting ring connects the plurality of shells together through the buckle, and the plurality of friction plates are pushed to fit together by the spring, and the spring pushes the friction plate to fit the friction plates on both sides tightly together.

[0006] Preferably, a groove is provided on one side of the friction plates that are in contact with each other, and the grooves on both sides are meshed with each other, so that when the friction plate on one side of the groove is stuck, sliding friction is generated between each other.

[0007] Preferably, a side of the housing away from the spring is provided with a plurality of connecting bolts arranged in a ring shape for connecting the power output end and the power input end.

[0008] Preferably, one side of the housing is connected to a transmission box via connecting bolts to provide power.

[0009] Preferably, the inner side wall of the shell is provided with a plurality of sliding grooves matched with the slider, so that the slider can drive the friction plate to slide inside the shell.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model achieves the purpose of preventing damage to the transmission box caused by accidental jamming through the friction plates, the housing and the springs. The friction plates on both sides are tightly fitted together. These springs ensure that the pressure between the two friction plates can ensure effective friction force without damaging the friction plates themselves due to overtightening.

[0012] When the system is operating normally, this design can ensure the efficient operation of the mechanical structure and reduce energy consumption. If the friction plate on one side is accidentally stuck, the stuck friction plate will immediately change the dynamic balance between the friction plates on both sides. In this special case, sliding friction will occur between the friction plates that originally matched perfectly. It can prevent the entire mechanical structure from suffering more serious damage due to one side being stuck. Through sliding friction, those mechanical parts that are still operating normally are protected, thus ensuring the stability and safety of the entire system. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting box 11 is connected to an oil inlet pipe 12. The oil inlet pipe 12 passes through an opening 14 opened on the outer shell 3 and is connected to a refueling port 5 at its end. A buckle 13 is fixed to the side of the outer shell 3, and a connecting ring 2 is buckled on the outer side of the buckle 13. The connecting ring 2 connects several outer shells 3 together through the buckle 13, and pushes several friction plates 8 to fit together through the spring 6, and the spring 6 pushes the friction plate 8 to fit the friction plates 8 on both sides tightly together.

[0023] Furthermore, a groove is provided on one side of the friction plate 8 that is in contact with each other, and the grooves on both sides are meshed with each other. When the friction plate 8 on one side of the groove is stuck, sliding friction is generated between the grooves.

[0024] Furthermore, a side of the housing 3 away from the spring 6 is provided with a plurality of connecting bolts 4 arranged in a ring shape for connecting the power output end and the power input end.

[0025] Furthermore, one side of the housing 3 is connected to a transmission box 1 via a connecting bolt 4 for providing power.

[0026] Furthermore, the inner wall of the housing 3 is provided with a plurality of sliding grooves matched with the slider 7 , so that the slider 7 can drive the friction plate 8 to slide inside the housing 3 .

[0027] Working principle: Its design includes a housing 3, and a plurality of telescopic rods 9 arranged in a ring are arranged inside. Each telescopic rod 9 is provided with a spring 6 on the outside, and a friction plate 8 is connected to the spring 6 and the end of the telescopic rod 9 away from the housing 3. The other side of the friction plate 8 is also fitted with the same friction plate 8, and the opposite side of the two friction plates 8 is provided with the same spring 6, telescopic rod 9 and housing 3 structure. In addition, an oil delivery pipe 10 arranged in the same ring is installed between the springs 6, and the end of the oil delivery pipe 10 away from the center of the circle is close to the side of the spring 6, and the end close to the center of the circle is connected to the side of the connecting box 11. The connecting box 11 is further connected to the oil inlet pipe 12, which extends through the opening 14 on the housing 3 and is provided with a refueling port 5 at the end, and the lubricating oil is squeezed into the refueling port 5, and is transported to the connecting box 11 through the oil inlet pipe 12, and then the lubricating oil is transported to the oil delivery pipe 10 through the connecting box 11, and finally sent to the spring 6 and the telescopic rod 9 through the oil delivery pipe 10 to provide lubrication for them.

[0028] A buckle ring 13 is fixed on the side of the housing 3, and the buckle ring 13 is buckled with a connecting ring 2, which is used to connect multiple housings 3, and the friction plate 8 inside the housing 3 is tightly fitted by the push of the spring 6, so as to provide the required friction force.

Not only does it improve the stability of the overall structure, but it also drives the friction plate 8 to rotate together.

[0029] When the friction plate 8 on one side stops rotating due to a mechanical failure, the friction plates 8 on both sides are transformed from static friction to sliding friction. As the grooves of the friction plates 8 are continuously misaligned, the slider 7 is driven to move, and the spring 6 ensures that the friction plates 8 on both sides remain in contact, ensuring that the equipment runs smoothly and efficiently.
