1. rotary braking
When fixed seat is maintained static, it is necessary to be carried out to revolving bed in the case that revolving bed has certain mass and rotating speed
Braking.Hydraulic jacking device jacking, makes the friction plate at the top of hydraulic jacking device be contacted with the friction passage of revolving bed bottom, and produce
The certain pressure of life, produces braking friction, realizes by moving quiet braking procedure.
2. revolution locking
When fixed seat and revolving bed are in inactive state, due to the working condition of whole mechanism, revolving bed is caused to be subject to
Certain external force influence, forms the relative movement tendency for turning, and now needs to lock revolving bed.Hydraulic jacking device jacking, makes
Friction plate at the top of hydraulic jacking device is contacted with the friction passage of revolving bed bottom, and produces certain pressure, produces braking to rub
Power is wiped, makes fixed seat to realize relatively rotating with revolving bed.
After revolution locking, the stress of whole mechanism is by pivoting support and jacking apparatus shared.And relative to revolution
Supporting raceway diameter, multiple jacking apparatus are uniformly distributed circumferentially in the entirety on bigger circumference, being conducive to improving mechanism surely
It is qualitative.
In sum, the present invention is a kind of rotary braking dress that dynamic brake and static locking can be realized to slew gear
Put, and with simple structure, easy to maintenance, mechanical stability is high, the features such as low cost of manufacture.
