Description

Technical Field

[0001] This utility model belongs to the field of mechanical transmission, and specifically relates to a device that reduces the transmission angle of a rotating shaft to enable the transmission shaft to transmit power smoothly. Background Technology

[0002] The development of automatic mechanical transmission angle adjustment devices is crucial for the industrial sector. By optimizing the angle of transmission components in real time, it can significantly reduce vibration, wear, and energy loss caused by angular deviations, thus extending equipment lifespan. Simultaneously, it improves transmission accuracy and system stability, adapting to complex operating conditions. This technology is key to driving the intelligent and energy-efficient upgrading of high-end equipment and has strategic value for performance breakthroughs and cost optimization in industries such as automotive, aerospace, and precision manufacturing.

[0003] Traditional transmission systems cannot automatically adapt their angles to working conditions, resulting in low precision and poor efficiency. Under dynamic working conditions, changes in the relative position of the working parts cause angle deviations, affecting system stability. In various scenarios, they need to adapt to different angles and offsets, which traditional devices cannot meet.

[0004] Excessive drive shaft angle can lead to the following problems: 1) Increased vibration and noise due to dynamic imbalance caused by angular deviation; 2) Accelerated wear of bearings and seals, with additional radial loads reducing component lifespan; 3) Reduced transmission efficiency due to energy dissipation under asymmetrical forces; 4) Increased coupling load, potentially causing fatigue fracture; 5) In extreme cases, it can lead to drive shaft bending, deformation, or breakage, endangering safe equipment operation. Strict control of installation angle tolerances is necessary to ensure system stability.

[0005] Therefore, there is an urgent need for a new technical solution to address this problem. Utility Model Content

[0023] As shown in the figure, a mechanical transmission angle automatic adjustment device is characterized by: including an angle swing support 6, an angle swing shaft 7 and an angle swing device bracket 8.

[0024] The angle swing device bracket 8 is mounted on the frame of the working machine; the angle swing device bracket 8 has mounting holes symmetrically arranged on both sides, and a bushing 1 is provided in the mounting hole. An angle swing shaft 7 is provided on the angle swing support 6. The angle swing shaft 7 cooperates with the bushing 1 to enable the angle swing support 6 to be mounted on the angle swing device bracket 8.

[0025] The angle swing support 6 is equipped with a gearbox 2 and a motor 3; the output end of the gearbox 2 is equipped with a power output shaft 4, and the power output shaft 4 is sequentially connected to the transmission shaft 11 and the load connecting shaft 10, and the connection method is through a universal joint 2.

[0026] The number of mounting holes is two; a bushing 1 is provided in the mounting hole, and the bushing 1 is connected to the angle swing shaft 7. When the machine swings during operation, the angle swing support 6 will swing through the angle swing shaft 7, so that the power output shaft 4 of the gearbox 2 can be connected to the transmission shaft 11 and the load connection shaft 10.

[0027] The bushing 1 and the angle swing shaft 7 cooperate with each other, and the angle swing support 6 can swing within the angle swing device bracket 8.

[0028] The bushing 1 is a copper-tin alloy bushing.

[0029] The device described in this application can automatically adjust the angle in real time according to the actual situation on site through a mechanical swing device, so as to minimize the transmission angle, improve transmission efficiency, and enhance transmission stability; it ensures the accuracy and reliability of steering, reduces energy consumption and wear, thereby comprehensively improving the vehicle's steering performance and driving experience, and meeting the market's urgent demand for flexible steering performance.

[0030] Specific structure: Motor 3 is fixedly installed on gearbox 2; gearbox 2 is fixedly installed on angle swing support 6 by bolt connection; angle swing support 6 has angle swing shafts 7 at both ends, angle swing shafts 7 are connected to angle swing device support 8 through bushing 1, angle swing support 6 can swing within angle swing device support 8 with bushing 1 as the axis; angle swing device bracket 8 is fixedly installed on the frame of tractor (working machine).

[0031] Working process: When the axis of the load connecting shaft 10 is on the same axis as the transmission shaft 11 and the power output shaft 4, the angle between the axis of the load connecting shaft 10 and the axis of the transmission shaft 11 and the power output shaft 4 is 180°, which is a straight line. The transmission resistance is small, the transmission is relatively smooth, and the mechanical transmission efficiency is high.

[0032] It is impossible to guarantee that the axis of the load connecting shaft 10 will be 180° with the axes of the drive shaft 11 and the power output shaft 4 during operation. Generally, the height of the working equipment is lowered during operation and raised during travel, which creates an angle between the axis of the load connecting shaft 10 and the drive shaft 11, and an angle between the drive shaft 11 and the power output shaft 4. Figure 5 As shown, the smaller these included angles are, the greater the transmission resistance, the greater the vibration, and the lower the mechanical transmission efficiency.

[0033] With the adoption of an automatic angle adjustment device, when lowering the height of the working equipment or raising the height of the working equipment during operation, the automatic angle adjustment device 13 swings accordingly within the angle swing device bracket 8. This increases the angle between the axis of the load connecting shaft 10 and the transmission shaft 11, and also increases the angle between the transmission shaft 11 and the power output shaft 4. Figure 6 As shown, as these included angles increase, the transmission resistance decreases, the vibration decreases, and the mechanical transmission efficiency is greatly improved.
