Description

Technical Field

[0001] The utility model relates to the technical field of couplings, and particularly relates to an elastic coupling for a power take-off of a mining truck. Background Art

[0002] A coupling is an important device in mechanical engineering. It is mainly used to connect two shafts or a shaft and a rotating part, and rotates together during the transmission of motion and power. Some couplings also have a certain overload protection ability to prevent the connected components from being damaged due to excessive torque.

[0003] A mining truck refers to a large truck used in the mining industry. A power take-off is an important component on a mining truck, also known as a power output device. The coupling installed on the power take-off of a mining truck bears a large torque and absorbs the impact load generated by the engine vibration at the same time.

[0004] When the coupling is impacted, it will affect the entire shafting equipment such as bearings and gears, causing noise during the operation of these components and reducing the service life of these components. Content of the Utility Model

[0005] The purpose of the utility model is to provide an elastic coupling for a power take-off of a mining truck. Through the combined action of a high-elastic coupling elastomer, a flexible vibration damping partition, a flexible vibration damping sleeve and a vibration damping spring, the shafting equipment such as a universal coupling is prevented from being damaged, and the service life of the shafting equipment is improved.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an elastic coupling for a power take-off of a mining truck, including an engine connection flange and a universal coupling connection hub. The universal coupling connection hub is arranged on the front side of the engine connection flange. The engine connection flange is the input end of power, and the universal coupling connection hub is the output end of power. A high-elastic coupling elastomer is sleeved on the outer end of the universal coupling connection hub;

[0007] A plurality of flange axial connection screws arranged horizontally are provided on the high-elastic coupling elastomer. The high-elastic coupling elastomer is connected to the engine connection flange through the flange axial connection screws. A plurality of hub radial connection screws arranged longitudinally are provided on the high-elastic coupling elastomer. The high-elastic coupling elastomer is connected to the universal coupling connection hub through the hub radial connection screws. The high-elastic coupling elastomer is used to connect the engine connection flange and the universal coupling connection hub. The engine connection flange drives the universal coupling connection hub to rotate through the high-elastic coupling elastomer. Since the high-elastic coupling elastomer has elasticity, it has a buffering effect during operation, absorbs the impact load, and plays a role in protecting the universal coupling.

[0008] Further, a plurality of flange mounting holes penetrating the engine coupling flange are provided on the engine coupling flange. The engine coupling flange is connected to the engine through the flange mounting holes. A plurality of universal coupling connection threaded holes are provided on the front side of the universal coupling connection hub. The universal coupling connection hub is connected to the universal coupling through the universal coupling connection threaded holes. Therefore, the engine and the universal coupling are connected through this coupling.

[0009] Further, a spring chamber is provided on the front side of the engine coupling flange. The spring chamber is located inside the universal coupling connection hub. A damping spring for buffering is provided inside the spring chamber. A damping adjustment bolt for adjusting the damping spring is provided on the universal coupling connection hub. The rear end of the damping adjustment bolt extends into the spring chamber and is connected to the damping spring. The damping spring uses its own elastic force to buffer during the operation of this coupling, and the rotation of the damping adjustment bolt can adjust the telescopic length of the damping spring, thereby adjusting the strength of the buffering ability of the damping spring.

[0010] Further, a flexible damping sleeve is sleeved on the outer end of the spring chamber. The flexible damping sleeve is clamped between the universal coupling connection hub and the spring chamber. A flexible damping partition is provided at the rear end of the flexible damping sleeve. The flexible damping partition is clamped between the engine coupling flange and the universal coupling connection hub. Both the flexible damping partition and the flexible damping sleeve are elastic and can further play a buffering role.

[0011] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0012] 1. Under the combined action of the high-elastic coupling elastomer, the flexible damping partition, the flexible damping sleeve and the damping spring, the vibration and load impact during the operation of this coupling are absorbed and buffered, thereby reducing noise, avoiding damage to shafting equipment such as universal couplings, and improving the service life of the shafting equipment;

[0013] 2. Rotating the damping adjustment bolt can drive the damping spring to expand and contract, adjust the original length of the damping spring, and then adjust the strength of the buffering ability of the damping spring, so as to adapt to different usage scenarios and improve the applicable range of this coupling.

Detailed implementation manners

[0022] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0023] The present utility model provides a Figures 1-5 mining truck power take-off elastic coupling as shown, which includes an engine connection flange 1 and a universal coupling connection hub 6. The universal coupling connection hub 6 is arranged on the front side of the engine connection flange 1. The engine connection flange 1 is the power input end, and the universal coupling connection hub 6 is the power output end. A high-elastic coupling elastomer 2 is sleeved on the outer end of the universal coupling connection hub 6;

[0024] A plurality of horizontally arranged flange axial connection screws 3 are provided on the high-elastic coupling elastomer 2. The high-elastic coupling elastomer 2 is connected to the engine connection flange 1 through the flange axial connection screws 3. A plurality of longitudinally arranged hub radial connection screws 10 are provided on the high-elastic coupling elastomer 2. The high-elastic coupling elastomer 2 is connected to the universal coupling connection hub 6 through the hub radial connection screws 10. The high-elastic coupling elastomer 2 is used to connect the engine connection flange 1 and the universal coupling connection hub 6. The engine connection flange 1 drives the universal coupling connection hub 6 to rotate through the high-elastic coupling elastomer 2. Since the high-elastic coupling elastomer 2 has elasticity, it has a buffering effect during operation, absorbs impact loads, and plays a role in protecting the universal coupling.

[0025] A plurality of flange mounting holes 101 penetrating the engine coupling flange 1 are provided on the engine coupling flange 1. The engine coupling flange 1 is connected to the engine through the flange mounting holes 101. A plurality of universal coupling coupling threaded holes 11 are provided on the front side of the universal coupling coupling hub 6. The universal coupling coupling hub 6 is connected to the universal coupling through the universal coupling coupling threaded holes 11. Therefore, the engine and the universal coupling are connected by this coupling.

[0026] One end of this coupling is the engine coupling flange 1. The engine coupling flange 1 is connected to the engine through the flange mounting holes 101. The other end is the universal coupling coupling hub 6, which is connected to the universal coupling through the universal coupling coupling threaded holes 11. In this way, the engine and the universal coupling are connected by this coupling. The engine can transmit torque through this coupling, thereby driving the universal coupling. And between the engine coupling flange 1 and the universal coupling coupling hub 6 is a highly elastic coupling elastomer 2 with elasticity. Therefore, during operation, the highly elastic coupling elastomer 2 can well absorb impact loads, compensate for axial, radial, and angular deviations, and play a good protective role for the universal coupling, avoiding the risk of fracture due to long-term operation.

[0027] To improve the scope of application, as Figures 1-3 shown, a spring chamber 7 is provided on the front side of the engine coupling flange 1. The spring chamber 7 is located inside the universal coupling coupling hub 6. A damping spring 8 for buffering is provided inside the spring chamber 7. A damping adjustment bolt 9 for adjusting the damping spring 8 is provided on the universal coupling coupling hub 6. The rear end of the damping adjustment bolt 9 extends into the spring chamber 7 and is connected to the damping spring 8. The damping spring 8 uses its own elastic force to play a buffering role during the operation of this coupling. And the rotation of the damping adjustment bolt 9 can adjust the telescopic length of the damping spring 8, thereby adjusting the strength of the buffering ability of the damping spring 8.

[0028] By providing the damping spring 8, the damping spring 8 can stretch and has elasticity. Its elasticity can buffer the load during the operation of this coupling. And rotating the damping adjustment bolt 9 can drive the damping spring 8 to stretch, adjust the original length of the damping spring 8, and thereby adjust the strength of the buffering ability of the damping spring 8, so as to adapt to different usage scenarios and improve the scope of application of this coupling.

[0029] To further improve the buffering ability, as Figure 3 、 4As shown, a flexible damping sleeve 5 is sleeved on the outer end of the spring chamber 7. The flexible damping sleeve 5 is clamped between the universal coupling joint shaft hub 6 and the spring chamber 7. A flexible damping partition 4 is provided at the rear end of the flexible damping sleeve 5. The flexible damping partition 4 is clamped between the engine connection flange 1 and the universal coupling joint shaft hub 6. Both the flexible damping partition 4 and the flexible damping sleeve 5 are elastic and can further play a buffering role.

[0030] A flexible damping partition 4 and a flexible damping sleeve 5 are provided at the outer end of the universal coupling joint shaft hub 6. Both of them are soft in texture and can further buffer the load and vibration impact during the operation of the coupling on the basis of the high-elastic coupling elastomer 2. Under the combined action of the high-elastic coupling elastomer 2, the flexible damping partition 4, the flexible damping sleeve 5 and the damping spring 8, the risk of vibration propagating along the shafting and gradually amplifying is avoided, the noise is reduced, the shafting equipment such as seals, bearings, gears, etc. are protected from the impact, the service life is prolonged, and the safety and comfort of the vehicle are enhanced.

[0031] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
