Abstract
A kind of elastic coupling, including pin, nut, left half-coupling and right half-coupling pass through pin attaching nut fixing joint, resilient sleeve is mounted on pin, retaining ring pad is equipped between left half-coupling and right half-coupling, resilient sleeve is single rubber sleeve, in use, motor torque is directly transmitted by the elastic coupling connecting with electric machine main shaft, also subject to the gravity of motor itself while transmitting motor traction force.When work, when side knock occurs, independent resilient sleeve is squeezed, or it banking squeezes, the deformation that not will drive resilient sleeve on other pins enables driving motor to generate biggish axially opposing displacement, to realize wheel to the elastomeric isolation of the high-frequency vibration between motor.Also there is certain vibration damping and absorbing effect, operate machine driving steadily, while also there is two axis relative displacements of compensation, buffering and vibration damping and function of safety protection.
Description
Technical field
The invention belongs to Clutch Technology fields, and in particular to a kind of elastic coupling.
Background technique
Current electric locomotive is all based on greatly the power drive system of induction machine and retarder, shaft coupling (also known as shaft coupling
Section) be driving system of locomotive bogie important component, traction electric machine axis and gear train assembly are linked together by it,
The torque of traction electric machine is transmitted to wheel by being driven linking portion to realize.The basic work of shaft coupling in drive system
With first is that between centers torque transmitting with one heart；Second is that adapt to the shaft shoulder between radially, axially and drift angle three-dimensional displacement；Three are to provide driving
The necessary elasticity of shafting, to reduce rotational noise.Shaft coupling between driving motor and train wheel hub is transmitted by intermediate pull ring
The tractive force of motor, shaft coupling only transmit power, are not subject to the gravity of motor itself.The deficiency of traditional machine driving mode
It is in not having vibration damping and absorbing effect, machine driving operating is not stable enough；Shaft coupling does not have the relative displacement of two axis
Compensating action, buffering and vibration-damping function are relatively weak；But also presence such as system noise is big, frictional dissipation is high, energy loss
Greatly, mechanical clearance or flexible deformation etc. influence system accuracy, drive system speed can not improve, system maintenance cost of upkeep is high,
The deficiencies of lifetime of system is short.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a kind of elastic coupling, elasticity connection
Joint has two axis relative displacements of compensation, buffering, vibration damping and function of safety protection.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of elastic coupling, including pin, nut, left half-coupling and right half-coupling join by the way that pin attaching nut is fixed
It closes, resilient sleeve is mounted on pin, and retaining ring pad is equipped between left half-coupling and right half-coupling, and resilient sleeve is single rubber
Set.
The through-hole of the pin is designed using counterbore, is distributed in homogeneous angular.
The left half-coupling and right half-coupling are equipped with keyway, convenient for the cooperation between connecting shaft.
The beneficial effects of the present invention are:
Traditional defect intrinsic with gearbox drive system is overcome, the mechanical clearance or machine of machine driving link are avoided
Tool flexible deformation etc. influences, and improves system control precision；Transmission efficiency is high, improves 20%-60%, energy conservation than legacy system efficiency
Effect is obvious；Small in size, light-weight, noise is low, and easy to maintain and maintenance cost is lower.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention is further discussed below below in conjunction with attached drawing.
As shown in Figure 1, a kind of elastic coupling, including pin 2, nut 6, left half-coupling 1 pass through with right half-coupling 4
2 attaching nut of pin, 6 fixing joint, resilient sleeve 3 are mounted on pin 2, are equipped between left half-coupling 1 and right half-coupling 4
Retaining ring pad 5, resilient sleeve 3 are single rubber sleeve.
The through-hole of the pin 2 is designed using counterbore, is distributed in homogeneous angular.
The left half-coupling is equipped with keyway 8 convenient for the cooperation between connecting shaft.
The right half-coupling is equipped with keyway 9 convenient for the cooperation between connecting shaft.
The working principle of the invention is:
In use, motor torque is directly transmitted by the elastic coupling connecting with electric machine main shaft, and the elasticity of the present embodiment
Shaft coupling is while transmitting motor traction force also subject to the gravity of motor itself.It is independent when side knock occurs when work
Resilient sleeve squeeze, or banking squeeze, not will drive the deformation of resilient sleeve on other pins, so that driving motor
Biggish axially opposing displacement can be generated, to realize wheel to the elastomeric isolation of the high-frequency vibration between motor.This implementation
The elastic coupling of example also has certain vibration damping and absorbing effect, operates machine driving steadily, while also having compensation two
Axis relative displacement, buffering and vibration damping and function of safety protection.
