Description
Technical field
A kind of shaft coupling category city rail vehicle component assembly technical field, relate generally to a kind of city rail vehicle running-in experiment connection
Axle device.
Background technology
City rail vehicle wheel is to simulate Special test platform of the wheel to working order to engaging experimental bench, can be to light before entrucking
Rail, iron tyre pair（There is axle box, without axle box）Running-in is carried out, i.e., in different rotating speeds and different rotary direction, by detecting gear
Judgement gear is analyzed in case, the temperature change of gearbox output shaft bearing and vibration severity change and the change of gear-box oil temperature
The adaptation state and performance of each part of case.So as to prevent because of Production of bearing and assembling quality problem, and the wheel triggered is early to operation
Hot axle, the hot box accident of phase, the further perfect detection to Production of bearing and assembling quality, transported for the safety of city rail vehicle
Row have it is important, shaft coupling be running-in experiment an important device, shaft coupling of the prior art due in structure not
Rationally, it is inaccurate to there is centering, in extraneous load-bearing or temperature suddenly change, the connective stability of shaft coupling declines, and influences reality
The normal operation tested or the deviation for causing experimental result.
The content of the invention
In order to solve the above problems, the invention discloses a kind of city rail vehicle running-in experiment shaft coupling, not only structure letter
It is single reasonable, and stability is high.
The object of the present invention is achieved like this：
A kind of city rail vehicle running-in experiment shaft coupling, including the first abutment shaft, the second abutment shaft and butt plate, set on butt plate
There is the first screwed hole circumferentially, butt plate is set in the outside of the second abutment shaft, the first abutment shaft and the second abutment shaft pair
Connect, the joint of first abutment shaft and butt plate is provided with the second screwed hole circumferentially, the first abutment shaft and butt plate
It is fixedly connected by the screw for sequentially passing through the second screwed hole and the first screwed hole, the center of butt plate is provided with annular slot, the
Two abutment shafts are provided with annular boss, annular boss and annular slot card and are connected, the transverse width of the annular slot for pair
The half of disk center's thickness is connect, the inwall of second fixing axle is provided with along the flat of the second abutment shaft length direction extension
Key.
Circular counter bore groove, the outside size matching pair of the abutment shaft of size first of counterbore groove are provided with the docking disk center
Should, the intercalation of the first docking shaft portion is in counterbore groove.
The ratio between the depth of the counterbore groove and the thickness of butt plate are 2:25, it is ensured that Stability Analysis of Structures, while strict centering.
The butt plate is provided with along the circumferentially uniform mounting hole of butt plate, the mounting hole and the distance for docking disk center
First screwed hole and the distance for docking disk center.
The number of the mounting hole is eight.
The present invention has the advantages that the present invention is simple and reasonable, passes through Self-locking sealing antitheft box compared with prior art
It is connected with screw thread installation, not only realizes strict structure centering, while during mechanical movement, by the external world
Carrying change or temperature change influence when, can to shaft coupling occur minor shifts compensate, increase shaft coupling
Connective stability, not only may insure being smoothed out for running-in experiment, while can test running-in and accurately be tested
As a result, experimental error is reduced.
