Description

Technical Field

[0001] The utility model specifically relates to the technical field of anti-reversal gears, in particular to a gear with an anti-reversal structure. Background Art

[0002] Gear transmission is the most widely used form of mechanical transmission. It has relatively accurate transmission, high efficiency, compact structure, reliable operation and long service life.

[0003] However, when the transmission gears are transmitting, they are driven by the rotating shaft to rotate, so as to achieve effective meshing with the matching gears, thereby achieving the transmission effect. However, in special working environments, the gears need to have an anti-reverse effect, so that when the gears are transmitting, they can only be transmitted in the same direction to prevent reversal between the gears, which will cause damage to the traditional structure inside the equipment.

[0004] After searching, Chinese patent publication number CN202021120929.5 discloses an anti-reverse double gear; including a rotating shaft, a gear one is sleeved on the rotating shaft, a gear two is also sleeved on the rotating shaft, the gear two rotates with the rotating shaft, and the gear two has an interference fit with the rotating shaft, the pitch circle diameter of the gear two is the same as that of the gear one, and the number of teeth of the gear two is different from that of the gear one;

[0005] When the transmission gear actively rotates, the structure in the above patent meshes with gear one and gear two to achieve meshing rotation of gear one and gear two. However, the rotation speed of gear one and the rotation speed of gear two in the above patent cannot be effectively rotated in the coaxial arrangement. Therefore, when the transmission is performed, the shaft cannot drive the device to rotate, and the transmission force cannot be transmitted.

[0006] In view of the above situation, we provide a gear with an anti-reversal structure. In this device, a ring is installed on the bearing, and the bearing is driven to rotate by the rotating shaft, so that the ring drives the anti-reversal plate on the edge to rotate. The anti-reversal plate is movably installed in the groove on the edge of the ring. In this way, when the anti-reversal plate rotates, it can only move from the deep end to the shallow end of the groove. In this way, the matching teeth on the anti-reversal plate are effectively meshed with the inner teeth, and the gear ring drives the outer teeth to rotate, effectively realizing the effect of external transmission. When the anti-reversal plate rotates from the shallow end to the deep end of the groove, the blocking body between the two adjacent grooves on the edge of the ring effectively prevents the anti-reversal plate from rotating, and effectively prevents the gear ring from driving the outer teeth to rotate in reverse, so that the effective one-way transmission equipment is not easy to be damaged. Utility Model Content

[0007] The purpose of the utility model is to provide a gear with an anti-reversal structure. In this device, the matching teeth on the anti-reversal plate movably installed on the ring can only achieve clockwise meshing with the inner teeth. In this way, when transmitting, the gear ring drives the outer teeth to rotate clockwise at the same time. When the anti-reversal plate rotates counterclockwise, the anti-reversal plate is effectively blocked by a blocking body between two adjacent grooves in the edge of the ring, effectively ensuring that the gear ring will not generate a counterclockwise transmission force, and effectively avoiding the counterclockwise rotation of the outer teeth; so as to solve the problems of the above-mentioned background technology.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A gear with an anti-reverse structure comprises a gear ring; the outer side of the gear ring is integrally provided with external teeth; the inner side of the gear ring is provided with internal teeth; the internal teeth are arranged at intervals; the internal teeth mesh with matching teeth;

[0010] As a further technical solution of the utility model, the mating teeth are integrally arranged at the edge of the anti-reversal plate; the anti-reversal plate is arranged in a fan shape; the side of the anti-reversal plate away from the mating teeth is connected to the ring through a connecting shaft; and a groove is provided on the edge of the ring.

[0011] As a further technical solution of the utility model, the grooves provided on the edge of the ferrule are arranged from deep to shallow; and circular holes are provided on both sides of the deep end of the grooves.

[0012] As a further technical solution of the utility model, a bearing is fixedly installed inside the ring, and a keyway matching the shaft is opened on the inner wall of the bearing.

[0013] As a further technical solution of the utility model, the anti-reversal sheet has a groove whose deep end moves horizontally toward the shallow end.

[0014] As a further technical solution of the utility model, symmetrical sealing plates are fixedly installed on both sides of the gear ring by bolts.

[0015] As a further technical solution of the utility model, the gear ring is coaxially arranged with the ferrule and the bearing; the thickness of the anti-reversal sheet is half of the thickness of the ferrule.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. In the utility model, when in use, the ferrule is installed outside the bearing, and the sleeve is effectively driven by the cooperation between the bearing and the rotating shaft. When the sleeve rotates, the anti-reversal plate movably installed on the edge of the sleeve realizes the translation of the deep end with the groove to the shallow end under the cooperation of the connecting shaft and the groove. When the anti-reversal plate moves, the cooperation between the matching teeth and the inner teeth is realized, and the gear ring drives the outer teeth to rotate and transmit;

[0018] 2. In the utility model, when the shaft drives the gear to rotate counterclockwise, the ferrule rotates in the opposite direction. At this time, the anti-reversal plate cannot rotate counterclockwise due to the obstruction of the blocking body between the two adjacent grooves on the edge of the ferrule. In this way, the matching teeth at the end of the anti-reversal plate cannot drive the inner teeth to rotate, which effectively prevents the gear ring from driving the outer teeth to rotate counterclockwise. This effectively ensures that the inside of the one-way transmission device is not easily damaged and ensures safe use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7In the embodiment of the utility model, a gear with an anti-reversal structure includes a gear ring 4; the outer side of the gear ring 4 is integrally provided with an external tooth 1; the inner side thereof is provided with an internal tooth 5; the internal tooth 5 is spaced apart from the internal tooth 5; the internal tooth 5 is meshed with the mating tooth 8;

[0029] The mating teeth 8 are integrally arranged at the edge of the anti-reversal plate 6; the anti-reversal plate 6 is arranged in a fan shape; the side of the anti-reversal plate 6 away from the mating teeth 8 is connected to the ring 7 through a connecting shaft; the edge of the ring 7 is provided with a groove 9.

[0030] Specifically, the groove 9 provided on the edge of the ferrule 7 is arranged from deep to shallow; round holes 10 are provided on both sides of the deep end of the groove 9;

[0031] The bearing 3 is fixedly installed inside the ferrule 7, and a keyway matching the shaft is provided on the inner wall of the bearing 3.

[0032] By adopting the above technical solution, when in use, the ferrule 7 is installed outside the bearing 3, and the sleeve 7 is effectively driven by the cooperation between the bearing 3 and the rotating shaft. When the sleeve 7 rotates, the anti-reversal plate 6 movably installed on the edge of the sleeve 7 is coordinated with the connecting shaft and the groove 9 to achieve translation from the deep end of the groove 9 to the shallow end. When the anti-reversal plate 6 moves, the coordination between the matching teeth 8 and the inner teeth 5 is achieved, so that the gear ring 4 drives the outer teeth 1 to rotate and transmit;

[0033] The anti-reversal sheet 6 has a groove 9 with the deep end shifted toward the shallow end.

[0034] In this embodiment, symmetrical sealing plates 2 are fixedly installed on both sides of the gear ring 4 by bolts;

[0035] The gear ring 4 is coaxially arranged with the ferrule 7 and the bearing 3 ; the thickness of the anti-reversal sheet 6 is half of the thickness of the ferrule 7 .

[0036] By adopting the above technical solution, when the shaft drives the gear to rotate counterclockwise, the ring 7 rotates in the opposite direction. At this time, the anti-reversal plate 6 cannot rotate counterclockwise due to the obstruction of the blocking body between the two adjacent grooves 9 on the edge of the ring 7. In this way, the matching teeth 8 at the end of the anti-reversal plate 6 cannot drive the inner teeth 5 to rotate, effectively preventing the gear ring 4 from driving the outer teeth 1 to rotate counterclockwise, thereby effectively ensuring that the inside of the one-way transmission device is not easily damaged and ensuring safe use.

[0037] The working principle of the utility model is as follows: when in use, the ferrule 7 is installed outside the bearing 3, and the sleeve 7 is effectively driven by the cooperation between the bearing 3 and the rotating shaft. When the sleeve 7 rotates, the anti-reversal piece 6 movably installed on the edge of the sleeve 7 is cooperated with the connecting shaft and the groove 9 to achieve the translation of the deep end of the groove 9 to the shallow end. When the anti-reversal piece 6 moves, the cooperation between the matching teeth 8 and the inner teeth 5 is achieved, so that the gear ring 4 drives the outer teeth 1 to rotate and transmit;

[0038] When the shaft drives the gear to rotate counterclockwise, the ring 7 rotates in the opposite direction. At this time, the anti-reversal plate 6 cannot rotate counterclockwise due to the obstruction of the blocking body between the two adjacent grooves 9 on the edge of the ring 7. In this way, the matching teeth 8 at the end of the anti-reversal plate 6 cannot drive the inner teeth 5 to rotate, effectively preventing the gear ring 4 from driving the outer teeth 1 to rotate counterclockwise, thereby effectively ensuring that the internal part of the one-way transmission device is not easily damaged and ensuring safe use.
