Flexible type energy storage device, and the flexible type power supply device between the flexible type energy storage device and gland.
The flexible type energy storage device includes assisting formula, ripple tub or corrugated plate type elastic energy storage located at the shoe cream room
Part, the flexible type power supply device include the elasticity energy supply diaphragm or silver located at the shoe cream room.
Its lubricating system of this engineering roller bit is not only simple in structure, rationally, and making easy to process；Particularly this reality
It can implement automatically to carry out the bearing arrangement during rock bit use certainly to a certain extent with new lubricating system
Adaptive make-up oil is moved, the continuous consumption to lubricating oil during use carries out continuous automatic pressure and adaptively supplemented, with
Ensure that bit cone, bearing arrangement part etc. are sufficiently lubricated from beginning to end；And then its safe running performance can be improved
And reliability, extend the service life of rock bit；Meanwhile its gear wheel and corresponding bearing（Axle journal）Seal have it is more preferable
Ground anti-wear performance and sealing property；Also, due to its attachment structure and the simple and reasonability of corresponding connected mode method, its
The base of drill bit is connected to by way of welding in corresponding brill chimb, and not only stable connection is reliable, when gear wheel occurs
Problem or service life have arrived, it is only necessary to pass through fastener（That is bolt or stud）Can fast and easy dismounting and change tooth from drilling pipe
Take turns drill bit；The maintenance and repair of rock bit can be increased substantially and change installation rate and efficiency, simplify its installation operation process,
Improve installation effectiveness.
