Problems solved by technology

Rail vehicles currently widely use the traditional coupling-drum gear coupling. Although this type of coupling can meet the use requirements of rail vehicles to a certain extent, in the long-term use process, the drum gear coupling is easy to There are disadvantages such as oil leakage, electric corrosion, and expensive maintenance (lubricating oil and grease need to be added frequently, and disassembly is inconvenient). In addition, the crown gear coupling cannot effectively attenuate the peak torque of the motor due to the absence of elastic elements. Affect the service life of the motor and gearbox

Abstract

The invention provides a coupling, which belongs to vehicle parts, and includes a driving shaft, on which a driving shaft flange is arranged; a driven shaft, on which a driven shaft flange is arranged; an elastic The elastic body includes a first elastic body arranged on the driving shaft flange and a second elastic body arranged on the driven shaft flange with the same structure; wherein, the first elastic body and the second elastic body The elastic bodies are connected through connecting flange components. The elastic body in the present invention has elasticity, can compensate displacement, and provide suitable flexibility in the torsional direction, eliminate torsional vibration transmitted by the shafting, and ensure smooth and low-noise operation of the vehicle.

Description

technical field [0001] The invention relates to a shaft coupling, which belongs to an input shaft coupling device for rail vehicles (such as subways and EMUs). Background technique [0002] In a mechanical system, different mechanical transmission devices require certain components to be connected to transmit motion and torque to the rear. Couplings have good displacement compensation performance and the ability to reduce vibration and noise in mechanical systems, so they are often used in the connection of mechanical transmission equipment widely used in vehicles, ships, lifting, chemical, logistics and other industries. In the field of rail transportation, the requirements for the transmission system of rail vehicles are extremely high, and the size of the transmission space is strictly limited. As a key component of the transmission system, the locomotive coupling is required to improve and optimize the axial vibration frequency and reduce the vibration amplitude. Axial ...
