The adaptive self-operated type accumulator of the shoe cream room includes the flexible type storage on the inside of the gland of the shoe cream room
Energy 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 hair
Bright lubricating system can be implemented to carry out the bearing arrangement during rock bit use automatically automatically certainly to a certain extent
Make-up oil is adapted to, the continuous consumption to lubricating oil during use carries out continuous automatic pressure and adaptively supplemented, to ensure
Bit cone, bearing arrangement part etc. are sufficiently lubricated from beginning to end；And then its safe running performance and can be improved
By property, extend the service life of rock bit；Meanwhile its gear wheel and corresponding bearing（Axle journal）Seal have it is preferably resistance to
Grind performance and sealing property；Also, due to its attachment structure and the simple and reasonability of corresponding connected mode method, its drill bit
Base be connected to by way of welding it is corresponding bore in chimb, not only stable connection is reliable, when gear wheel goes wrong
Or service life has arrived, it is only necessary to passes through fastener（That is bolt or stud）Can fast and easy dismounting and change rotary drill from drilling pipe
Head；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.
