In order to achieve effective power transmission, the connection structure of the transmission shaft is crucial. In traditional belt drive systems, the belt connection is usually connected through a simple plane surface connection or fixed to the shaft with a buckle. This connection method has some problems: easy slippage and low transmission efficiency.

[0003] In order to improve transmission efficiency and reliability, a connection structure of a transmission shaft is proposed. Utility Model Content

[0010] A further improvement of the technical solution of the utility model is that the outer surface of the rubber wheel is drivingly connected to the outer surface of the transmission belt.

[0011] A further improvement of the technical solution of the utility model is that: a passive tooth is fixedly installed on the outer surface of the transmission shaft, and an output tooth is fixedly installed after the right end of the passive tooth penetrates the machine body.

[0012] A further improvement of the technical solution of the utility model is that: the transmission shaft is rotatably installed in the machine body.

[0013] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0014] 1. The utility model provides a connection structure of a transmission shaft, in which a transmission belt is driven to rotate by a driving assembly, and cooperates with an output assembly to form a circulating power output mechanism, and the driving teeth are driven to rotate by the power output end, thereby driving the transmission belt, and the output assembly in the right end of the transmission belt is driven to rotate to output power, and a roller is rotatably mounted on a base block through a first bearing, and the outer surface of the roller is rollingly connected to the inner wall of the transmission belt, and the roller has two rows, upper and lower, and is in contact with the top inner wall and the bottom inner wall of the transmission belt, and plays a role of stable support and limiting when the transmission belt transmits cyclic power, preventing the transmission belt from deviating, and being in a taut state, so that the power transmission is more stable.

[0015] 2. The utility model provides a connection structure of a transmission shaft, in which the outer surfaces of both ends of the transmission belt are transmission-connected with a resistance-increasing mechanism, and the two ends of the transmission belt are clamped between the resistance-increasing mechanism and the driving teeth of the driving component. When the driving force required at the output component end increases, that is, when the resistance at the power output end of the connection structure of the transmission shaft becomes larger, the traditional belt connection mainly transmits torque and power through friction and tension, and the torque and power are fixed values, that is, after exceeding a certain value, it will cause the belt and the driving component to slip. Insufficient friction leads to a small driving force and instability. The connection structure of the transmission shaft pushes the rotating shaft through the hydraulic cylinder, thereby pushing the rubber wheel on the outer surface of the second bearing to push the two ends of the transmission belt, which can further clamp the two ends of the transmission belt between the resistance-increasing mechanism and the driving teeth of the driving component, so that when the driving force increases, the friction between the two ends of the transmission belt and the resistance-increasing mechanism and the driving component increases, and no slipping occurs. When not in use in daily life, the resistance-increasing mechanism is retracted by the hydraulic cylinder to reduce friction.

The utility model provides a connection structure of a transmission shaft, in which a passive tooth is rotatably installed in the right end of a base through the transmission shaft, and the outer surface of the passive tooth is in contact with the inner wall of a transmission belt for transmission connection. When the transmission belt rotates, the transmission shaft is driven to rotate through the passive tooth, and the output tooth at one end of the transmission shaft is meshed with an external driven component to transmit power. The connection structure of the transmission shaft maintains the tension and friction of the belt through a resistance increasing mechanism, thereby realizing power transmission.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] like Figure 1-5 As shown, the utility model provides a connection structure of a transmission shaft, including a body 1, a support assembly 6 is arranged inside the body 1, the outer surface of the support assembly 6 is transmission-connected with a transmission belt 2, the left end of the transmission belt 2 is sleeved with a drive assembly 4, the right end of the transmission belt 2 is sleeved with an output assembly 5, and the outer surfaces of both ends of the transmission belt 2 are transmission-connected with a resistance-increasing mechanism 3.

[0025] like Figure 2 As shown, the utility model provides a technical solution: preferably, the driving component 4 includes a power output end 41, one end of the power output end 41 is driven and installed with a driving tooth 42, and the outer surface of the driving tooth 42 engages with the transmission belt 2.

[0026] In this embodiment, the transmission belt 2 is driven to rotate by the driving component 4, and cooperates with the output component 5 to form a circulating power output mechanism. The driving tooth 42 is driven to rotate through the power output end 41, thereby driving the transmission belt 2 to transmit. The transmission belt 2 drives the output component 5 in the right end to rotate for power transmission output.

[0027] like Figure 3 As shown, the utility model provides a technical solution: preferably, the support assembly 6 includes a base block 63, a first bearing 61 is fixedly installed inside the base block 63, rollers 62 are rotatably inserted at both ends of the first bearing 61, and the outer surface of the roller 62 is rollingly connected to the inner wall of the transmission belt 2.

[0028] In this embodiment, the roller 62 is rotatably mounted on the base block 63 through the first bearing 61, and the outer surface of the roller 62 is rollingly connected to the inner wall of the transmission belt 2. The roller 62 has two rows, upper and lower, and is in contact and connected with the top inner wall and the bottom inner wall of the transmission belt 2. When the transmission belt 2 circulates power, it plays a role of stable support and limitation, preventing the transmission belt 2 from deviating, and is in a taut state, making the power transmission more stable.

[0029] like Figure 4 As shown, the utility model provides a technical solution: preferably, the resistance increasing mechanism 3 includes a hydraulic cylinder 31, a rotating shaft 34 is fixedly installed at one end of the hydraulic cylinder 31, a second bearing 33 is rotatably installed in the middle of the rotating shaft 34, and the outer surface of the second bearing 33 is sleeved with a rubber wheel 32, and the outer surface of the rubber wheel 32 is transmission-connected to the outer surface of the transmission belt 2.

[0030] In this embodiment, the outer surfaces of both ends of the transmission belt 2 are transmission-connected with a resistance-increasing mechanism 3, and the two ends of the transmission belt 2 are clamped between the resistance-increasing mechanism 3 and the driving teeth 42 of the driving component 4. When the driving force required at the output component 5 end increases, that is, when the resistance at the power output end of the connecting structure of the transmission shaft increases, the traditional belt connection mainly transmits torque and power through friction and tension, and the torque and power are fixed values, that is, after exceeding a certain value, the belt and the driving component 4 will slip. Insufficient friction leads to a small driving force and instability. The connecting structure of the transmission shaft pushes the rotating shaft 34 through the hydraulic cylinder 31, thereby pushing the rubber wheel 32 on the outer surface of the second bearing 33 to push the two ends of the transmission belt 2. The two ends of the transmission belt 2 can be further clamped between the resistance-increasing mechanism 3 and the driving teeth 42 of the driving component 4, so that when the driving force increases, the friction between the two ends of the transmission belt 2 and the resistance-increasing mechanism 3 and the driving component 4 increases, and no slipping occurs. When not in use in daily life, the resistance-increasing mechanism 3 is retracted by the hydraulic cylinder 31 to reduce friction.

[0031] like Figure 5 As shown, the utility model provides a technical solution: preferably, the output component 5 includes a transmission shaft 51, a passive tooth 53 is fixedly installed on the outer surface of the transmission shaft 51, the right end of the passive tooth 53 passes through the body 1 and is fixedly installed with an output tooth 52, and the transmission shaft 51 is rotatably installed in the body 1.

[0032] In this embodiment, the passive tooth 53 is rotatably installed in the right end of the base 1 through the transmission shaft 51. The outer surface of the passive tooth 53 is in contact with the inner wall of the transmission belt 2 for transmission connection. When the transmission belt 2 rotates, the transmission shaft 51 is driven to rotate through the passive tooth 53. The output tooth 52 at one end of the transmission shaft 51 is meshed and connected with the external driven component, thereby transmitting power. The connection structure of the transmission shaft maintains the tension and friction of the belt through the resistance increasing mechanism 3, thereby realizing power transmission.

[0033] The working principle of the connection structure of the transmission shaft is described in detail below.

[0034] like Figure 1-5 As shown, the transmission belt 2 is driven to rotate by the driving component 4, and cooperates with the output component 5 to form a circulating power output mechanism. The driving tooth 42 is driven to rotate by the power output end 41, thereby driving the transmission belt 2 to transmit. The output component 5 in the right end of the transmission belt 2 drives the transmission to rotate for power transmission output. The roller 62 is rotatably installed on the base block 63 through the first bearing 61, and the outer surface of the roller 62 is rollingly connected with the inner wall of the transmission belt 2. The roller 62 has two rows, upper and lower, and is in contact with the top inner wall and the bottom inner wall of the transmission belt 2. It plays a stable support and limiting role when the transmission belt 2 is cyclically transmitted, preventing the transmission belt 2 from running off, and is in a taut state, making the power transmission more stable. The outer surfaces of both ends of the transmission belt 2 are transmission-connected with the resistance-increasing mechanism 3, and the two ends of the transmission belt 2 are clamped between the resistance-increasing mechanism 3 and the driving tooth 42 of the driving component 4. When the driving force required by the output component 5 end increases, that is, when the resistance of the power output end of the connecting structure of the transmission shaft becomes larger, the traditional belt connection mainly transmits torque and power through friction and tension, and the torque and power are fixed values, that is, When it exceeds a certain value, it will cause the belt and the driving component 4 to slip. The insufficient friction force leads to a small driving force and is not stable enough. The connecting structure of the transmission shaft pushes the rotating shaft 34 through the hydraulic cylinder 31, thereby pushing the rubber wheel 32 on the outer surface of the second bearing 33 to push the two ends of the transmission belt 2. The two ends of the transmission belt 2 can be further clamped between the resistance increasing mechanism 3 and the driving teeth 42 of the driving component 4, so that when the driving force increases, the friction between the two ends of the transmission belt 2 and the resistance increasing mechanism 3 and the driving component 4 increases, and no slipping occurs. When not in use, the resistance increasing mechanism 3 is retracted by the hydraulic cylinder 31 to reduce the friction force. The passive tooth 53 is rotatably installed in the right end of the base 1 through the transmission shaft 51. The outer surface of the passive tooth 53 is in contact with the inner wall of the transmission belt 2 for transmission connection. When the transmission belt 2 rotates, the transmission shaft 51 is driven to rotate through the passive tooth 53. The output tooth 52 at one end of the transmission shaft 51 is meshed and connected with the external driven component, thereby transmitting power. The connecting structure of the transmission shaft maintains the tension and friction of the belt through the resistance increasing mechanism 3, thereby realizing the transmission of power.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
