Description
Technical field
The utility model relates to a kind of novel hydraulic speed-regulating case.
Background technique
Domestic petroleum rig transmission at present has two kinds of forms, and the one, adopt gear reduction box, the 2nd, adopt hydraulic coupler-speed regulation.Adopt speed reducer to slow down, can not speed governing, make rig under any power situation, rotating speed is constant, has wasted the energy.Simple hydraulic coupler-speed regulation case is because speed adjustable range is bigger, and the fluid coupling heating is serious, so rate of fault is higher, greatly influenced the normal operation of rig, need often stop to bore maintenance, drilling cost and cost are increased, working efficiency is also had a strong impact on.
Summary of the invention
The technical problem that the utility model solves: design a kind of novel hydraulic speed-regulating case, the mode that adopts fluid coupling and speed reducer to unite two into one realizes stepless change and deceleration.The one, the mechanical property of raising oil-well rig that can be bigger reduces power loss, and energy saving is increased economic efficiency.The 2nd, the speed adjustable range of fluid coupling is dwindled greatly, make fluid coupling in certain operating range, carry out stepless time adjustment, thereby avoided the coupler heating, guaranteed the normal operation of rig, reduce drilling cost and cost, improved the rig working efficiency.
Technical solution of the present utility model: a kind of novel hydraulic speed-regulating case, comprise casing (1), casing (1) is separated into two-part by dividing plate (10), left part in the casing (1) is fluid coupling (2), right part in the casing (1) is gear reduction box (5), the input shaft (3) of fluid coupling (2) links to each other with the main shaft of power engine, the output shaft (4) of fluid coupling (2) connects with the input shaft (6) of gear reduction box (5), and the output shaft (7) of gear reduction box (5) links to each other with working machine.
Be fixed with small gear (8) on the output shaft (4) of fluid coupling (2), be fixed with gearwheel (9) on the output shaft (7) of gear reduction box (5), small gear (8) is meshed with gearwheel (9), and small gear (8) all is positioned at gear reduction box (5) with gearwheel (9).
Advantage that the utility model compared with prior art has and effect:
1, the utility model mode of adopting fluid coupling and speed reducer to unite two into one realizes stepless change and deceleration, adapted to coupling with high-power slow-speed of revolution working machine, be installed between oil-well rig power engine and the working machine, can be along with watt level in the drill drilling process is regulated the rotating speed speed, to satisfy the requirement of different capacity to rotating speed, realize stepless time adjustment, reach optimum working efficiency, reduce the waste that the rig power loss causes, realized the raising of oil-well rig mechanical property and the saving of the energy preferably.
2, the utility model combines fluid coupling and gear reduction box, and the one, realized the soft start (No Load Start) when rig starts, guarantee that the rig mechanical part is not damaged, and can control the oil mass size and quicken or slow down.The 2nd, adopt gear reduction box at output terminal, the speed adjustable range of fluid coupling is dwindled greatly, make fluid coupling in certain operating range, carry out stepless time adjustment, thereby avoided the coupler heating, improved the reliability of coupler rotor, guarantee the normal operation of rig, reduced drilling cost and cost, improved the rig working efficiency.Reduce expenses about 1,000,000 yuan every year through calculating every bench drill machine.

Embodiment
1,2,3 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of novel hydraulic speed-regulating case, its casing (1) is separated into two-part by dividing plate (10), left part in the casing (1) is fluid coupling (2), right part in the casing (1) is gear reduction box (5), the input shaft (3) of fluid coupling (2) links to each other with the main shaft of power engine, be fixed with small gear (8) on the output shaft (4) of fluid coupling (2), be fixed with gearwheel (9) on the output shaft (7) of gear reduction box (5), small gear (8) is meshed with gearwheel (9), and small gear (8) all is positioned at gear reduction box (5) with gearwheel (9), and the output shaft (7) of gear reduction box (5) links to each other with working machine.
Speed control principle: during the fluid coupling running, the major cycle oil pump sucks the working oil in the coupler fuel tank, enters active chamber through the pump impeller oiler, and simultaneously, the fluid in the active chamber leaks into shell (scoop tube chamber) from pump impeller draining hole, has formed a circulation oil ring.Like this, just can utilize the oil mass in arrangements for speed regulation (electric actuator and rod member) the manipulation scoop tube radial expansion change active chamber, realize step-less adjustment output speed.The oil that conduit is discharged is got back to fuel tank by the oil extraction device.When active chamber is empty, empty load of motor starting/working machine lowest speed, when active chamber partly is full of, motor sub load/working machine speed governing, when active chamber was full of entirely, motor full load/working machine was at full speed.
The deceleration principle: the fluid coupling output terminal adopts gear reduction box to slow down, input speed can be reduced to output speed in a big way, make the fluid coupling output speed adjust reduction of speed within the specific limits, solved the excessive heating phenomenon that causes of coupler reduction of speed scope effectively, improve the reliability of coupler rotor, thereby adapted to the coupling with high-power slow-speed of revolution working machine.
