Background technology
Low speed shaft brake efficiency test platform be inertia load dynamic test stand, mainly have motor, rotary encoder,
Main shaft, inertia disc, reductor, spring bearing, brake hard disk, inertia disk control system, braking couple and brake couple
More changing device forms.For low speed shaft brake because braking moment is especially big, brake force is also big, and is braking couple single shoe brake,
During dynamic test, for braking moment sometimes up to 400000Nm, some is even more big, thus braking couple cannot cantilever installation,
To avoid huge brake force from causing, the amplitude of main shaft is excessive and bearing impact is excessive.Therefore it is also provided with the outside of braking couple
One bearing so that braking couple has bearings in main shaft both sides, and inertia impact load is reduced during experiment to examination
Test the destruction of platform.
Slow-speed shaft brake model multi-size, center height is different, braking width of jaw is different, is needed when so testing
Coordinate the braking couple (brake disc) adaptable with brake center height and braking width of jaw.And brake the axle on the outside of couple
The replacing for hindering braking couple is held, the bearing and its bearing block volume and weight are larger, more preferable in order to improve braking couple
Efficiency, bearing and bearing block are not dismantled, it is necessary to which overall remove bearing and bearing block, to change braking couple.
Utility model content

Brake couple more changing device, so as to substantially increase using flexible, it is convenient to change braking couple, improve functional reliability and
Convenience.
Technical scheme is as follows used by the utility model：
A kind of braking couple more changing device of low speed shaft brake efficiency test platform, brake the structure of couple more changing device
For：It is fixed with support on the base, the support is provided with cabinet, is gear mechanism in the cabinet, and the one of the cabinet
End connection handwheel, the handwheel are connected by rocking bar with gear mechanism, the other end connection pull bar of the cabinet, the push-and-pull
Bar is connected with the bearing block of spindle nose bearing, and end bearing fixed bolt hole and shifting bolt are provided with the bearing block
Hole, the bottom of the bearing block are provided with rail plate.
The beneficial effects of the utility model are as follows：
The utility model is compact-sized, reasonable, easy to operate, and low speed can be conveniently accomplished by the utility model device
The experiment of shaft brake efficiency test, there is provided braking couple more changing device, in that context it may be convenient to braking couple is dismantled and changes, with
Adapt to different centre-heights and brake the brake experiment of width of jaw.Whole work is flexible, and functional reliability is good, work
Efficiency high.
Bearing and bearing block integrally can be removed and reduced together by the utility model, axle when avoiding replacing braking couple
Hold and the disintegration of bearing block and reinstall, improve the efficiency that braking couple is changed.
